CA Wily Introscope for Monitoring SAP CC 4.0

To enable application analysis (including performance monitoring and root cause analysis), CA Wily Introscope (IS) is integrated into SAP Solution Manager Diagnostics (SMD). SAP provides CA Wily IS instrumentation for SAP CC 4.0 in combination with SAP Solution Manager 7.0 EhP1 SP23.

CA Wily IS is an application management solution for Java applications. It offers dashboards for performance and stability analysis. In addition, IS Investigator provides a detailed view on all applications and environment metrics reported by the IS agent to the IS Enterprise Manager, which is the CA Wily IS server and part of SAP Solution Manager.

To enable IS for SAP CC 4.0, you can install and configure the IS Java agent on the SAP CC hosts with the SAPInst of SAP Convergent Charging. Metrics, which are known as tracers in Probe Builder Directives (.pbd) files, define the information that collected at runtime. The IS Java agent collects this information from the applications and JVM. The IS Enterprise Manager stores metrics reported for further analysis. You can view performance metrics using the IS Workstation client or the WebViewer application.

You can set up Solution Manager Diagnostics after you set up your SAP CC system landscape. For information about setting up Solution Manager System Landscape and Diagnostics, see SAP Note .

The SAP Management Console (SAP MC) provides a common framework for centralized system management. It allows you to monitor and perform basic administration tasks on the SAP system centrally, thus simplifying system administration. Using the SAP MC you can:

Monitor and control (start, stop, or restart) the SAP systems, ABAP and Java instances with a single tool.

Display SAP system log and trace files, start profiles, instance parameters, the system environment, SAP environment, and so on.

Display and control Java and ABAP processes. Monitor system alerts. Save the current console configuration in a file to reuse it later or to forward it to other users. Start third-party tools (such as Telnet), if available, to manage an application server.

The SAP Management Console in the SAP NetWeaver AS is available in two modes:

SAP Management Console

The SAP MC is a Java applet that can be run from any Web browser supporting Java. Thus, you can administer remote systems without needing a local installation.

Standalone SAP Microsoft Management Console

SAP has developed the SAP Systems Manager snap-in which allows you to monitor, start or stop the SAP system centrally from the SAP Microsoft Management Console (SAP MMC.) The SAP MMC is available for Windows only. More information:

Monitoring works as an early warning system that monitors and displays the status of multiple systems and independent business components.

Monitoring of SAP Technology is an essential task during solution operation of SAP Technology. Deploying a monitoring architecture enables system administrators to get an overview of the system infrastructure at a glance and provides an infrastructure to gather and manage system information. The main features of the monitoring architecture are:

User-definable alert monitors for critical system events Method assignments to analyze alerts and react to them automatically Performance system to display recent performance data graphically

In your SAP CC 4.0 project, use SAP Solution Manager 7.0 EhP1 to:

Define your Application Landscape Define the Monitors and Thresholds for SAP CC 4.0

Installation Considerations Listed below are a few installation requirements:

Connect each SAP CC 4.0 system landscape to the SAP Solution Manager system. This is required, so that in the event of a support-relevant incident within your SAP system landscape, SAP Support Team can remotely access the SAP Solution Manager that hosts the affected system landscape.

Model and configure System Monitoring for SAP CC 4.0 based on SAP Solution Manager’s Computing Center Management System (CCMS).

CAUTION

Do not install SAP Solution Manager as a central component, if you want to reduce the risk of unavailability. Instead, operate a two-system landscape with test and production environment of SAP Solution Manager, especially if you are using time-critical functions such as Support Desk.

If you develop your own content, we recommend that you set up a three-system landscape with development, test, and production environment.

The monitor will present its status and alerts according to the presence and severity of log entries in the SAP Convergent Charging log files. If errors occur in a log file, they are displayed in transaction CCMS (RZ20) via "Open Alerts".

Operating System Monitoring The server machines hosting the SAP Convergent Charging application are monitored for resource consumption. Operating system metrics like overall CPU and memory consumption are reported. In addition, the Operating System processes java.exe are monitored for resource consumption. You can customize the thresholds for alert triggering to suit our individual needs.

Recommendation by SAP Install and use CCMS-based System Monitoring for SAP CC 4.0. Follow the setup procedure outlined in SAP Note .



Offline Charging Scenario Variant

Use the to monitor the business operations performed by the SAP CC BART Server system:

Offline acquisition of service consumption information from mediation system

You can monitor the acquisition sessions collecting the Consumption Detail Records (CDRs) that relate to customer service usage

Offline charging

You can monitor the batch rating and charging sessions running or scheduled in the systems.

NOTES

For each SAP CC server system, there is a specific log file for containing console error messages. In the following, the <HOME> directory refers to the path: /usr/sap/<SID>/<INSTANCE_NAME>/

where <SID> is specified at installation (and is the unique ID of the SAP system) and <INSTANCE_NAME> is automatically assigned to an instance by SAPInst and is composed of three characters and two digit that represent the instance number Note that <INSTANCE_NB> is different from <INSTANCE_ID>. Consult the SAP CC Installation Guide for more details.

The <WORKING_DIRECTORY> is a particular shared repository defined at the installation time. See the SAP CC Installation Guide for more details.

SQL failure files

When a SQL failure occurs during a batch rating and charging session, the BART Server system securely stops all on-going processes, saves the list of CDRs being charged to files and shuts down to prevent any other failure.

The lists of pending CDRs in process are saved to sql failures files.

The sql failure files are reloaded when the BART Server system restarts and the content is then committed to the running database.

The function prevents the system from triggering faulty batch charging sessions which may lead to inconsistencies in price computation.

Configuration Files

All the components of SAP CC 4.0 use some configuration files located in the <HOME>/config/ installation folder. Templates are also provided (*.sk extension) for facilitating the management of these configuration files.

Core Server The SAP CC Core Server system uses mostly configurations stored in SAP CC Core Database in the following database tables:

INSTANCE_CONFIGURATION CONFIGURATION CERT_STORE INSTANCE_CERT_STORE

You can use the and the to view or change the system settings relating to system processes or business processes.

BART Server The SAP CC BART Server system uses a single configuration file (bart.config) in read/write access. Its file format uses the ISO 8859-1 character encoding.

Some settings are stored in SAP CC BART Database in the CERT_STORE and INSTANCE_CERT_STORE database tables. You can use the to view or change the security certificates

Recommendation by SAP AG For taking into account the parameter changes, the server systems must be restarted. In a production environment, schedule always these operations during a specific low traffic period: A downtime is necessary and this process can temporarily decrease the performances of SAP CC. Consult the “High Availability” section in this document [page ].

You need to back up your system landscape regularly to ensure that you can restore and recover it in case of failure.

Backup and Restore Strategy

The backup and restore strategy for SAP CC 4.0 consists of two parts:

Backup and restore coverage for each component (see table below) Cross-system data dependencies and handling

The backup and restore strategy for your system landscape should not only consider SAP systems but should also be embedded in overall business requirements and incorporate your company’s entire process flow.




http://help.sap.com/saphelp_cc40/helpdata/en/e4/core_paramref

In addition, the backup and restore strategy must cover disaster recovery processes, such as the loss of a data center through fire. It is most important in this context that you ensure that backup devices are not lost together with normal data storage (separation of storage locations).

Based on the type of application data a component holds, we have used a categorization scheme that can be used to analyze the backup requirements of any system component and to easily determine an appropriate backup method for this component.

The following table contains the component list of SAP CC 4.0 and the appropriate categories:


Category Data for Backup and Restore Backup Method for Application Data

General Recommendations

You must regularly test your backup and restore strategy. A single test is insufficient, since the SAP CC 4.0 system landscape is likely to change and render a given strategy redundant. System administrators need an up-to-date backup and recovery strategy to restore failed systems.

SAP recommends that you perform a backup:

After the initial installation and configuration of the SAP CC 4.0 system landscape After specific changes, such as changes to the configuration, software update of individual

components, or replacement of components made to the system landscape. This of course depends on the frequency of such changes.

When you decide which components or which parts of the components to back up, consider the following factors:

Time required for a complete reinstallation Time required for additional configuration Effects of the expected downtime of one or more infrastructure components with regard to the

overall availability of the landscape

A backup process must ensure:

Logical consistency Restore the SAP CC 4.0 system landscape (cross-system data consistency) to a consistent status: The restoration applies at document level at the time of the backup. This includes the successful rollback of all open business transactions with respect to the exchange of data.

Physical consistency Restore individual SAP CC 4.0 components to a consistent state, followed by a successful startup of the restored components, and a successful reconnection to other components. Physical consistency provides a working runtime environment in which newly created business data can be exchanged. This is required to develop a transactional conduct on user level to react to broken workflows and outdated documents appearing after the restoration.

Detailed Backup and Restore

When you plan a backup and restore strategy for application data, software and configuration files, you must consider the following elements:

Operating system Database data files Database software SAP software and file systems Log files (SAP and others) Software of other system components (file systems and configuration files)

A component that has application data (a database, for example) usually comprises application software and configuration files (runtime infrastructure) that need a backup as well. A component,

which contains no application data, may comprise configuration files and software that require a backup.

The following table lists various elements of components and details the necessary data that needs backup or needs to be restored in each category.

The following sections describe specific information about the various elements you must consider, such as, the operating system used, the database software, and so on, when you plan a backup and restore strategy for application, software, and configuration files.

Operating System, Software and Configuration Data

Apart from business-critical application data (generally held in databases), you can also back up the system and application software (including configuration files). If you do this, you do not have to reinstall the system and application software if the software becomes damaged.

It is always possible to reinstall the operating system, software, and configuration data. However, reinstallation and configuration can take a long time. Therefore, if a backup of the software and configuration is available, you can reduce the time needed to restore your system after a system failure.

Online Backup The data contained in the database can be backed up online; however, it is not possible to do the same for the runtime infrastructure. An online backup refers to the system landscape and not the databases that contain the business-critical application, or the infrastructure components.

If you perform a backup while the server is running, open files may not be backed up.

File System Backup versus Full System Backup A file system backup only applies to specific files or files systems, whereas a full system backup applies to all files and file systems, including the operating system.

After installation of new software components, certain entries in the configuration files of the operating system cannot be found in the file systems in which the software installation occurred.

SAP therefore recommends that you perform a full system backup after installation, and that you back up the file systems of the installed software and the operating system on a regular basis.

For more information concerning possible backup scenarios, see on SAP Service Marketplace at: Advanced Technology Group Backup & Restore Documentation .

Database for SAP CC 4.0

SAP recommends that you run the database in archive mode.

This means that all actions on the database that modify data are recorded by the database and written to a transaction log. With regular full backups of your database (either offline or online), as well as a complete set of transaction logs since the last backup, it is possible to restore a crashed database to any point in time before the database crashed.

Backing up a Database

To ensure recoverability of your system, it is recommended to regularly backup the Core and BART databases. When using Oracle or Microsoft SQL Server RDBMS, refer to the normal database procedures. When using a Sybase ASE database, refer to the SAP Notes and , which describes how to setup automatic backups of data and log files.

For SAP Convergent Charging, we recommend to dump transaction logs at least every hour to ensure that the logs do not fill up the devices.

Restoring a Database Restore the Core Database or the BART Database using the normal database procedures. See the database documentation for details.

To have valid data for the invoicing and billing processes, SAP CC must compute all the relevant periodic fees. This computation must be compliant with the billing process and potential billing cycles.

An external scheduler can be plugged by the implementation project team to regularly trigger the activation of periodic fees for provider contracts or subscriptions. Refer to the relevant documentation.

SAP CC provides an internal scheduler to trigger the automated activation of periodic and one-off fees (see recurring rates and one-shot rates) of subscriptions for end customers. This scheduler does not take into account the provider contracts. Refer to the System Parameter Reference about the configuration of the ACTIVATION_SCHEDULER_ENABLED parameter and other related parameters.

Required Manual Periodic Tasks

This chapter describes all manual tasks required to run periodically in order to keep the application running smoothly over time. A manual task needs a person to for each execute in opposite to the scheduled tasks listed above which can be automated using a task scheduler program. Such tasks may be required on component level and are therefore relevant in each scenario that uses the component.

It is important that you monitor the successful execution of these tasks on a regular basis.

CAUTION

The periodic tasks are defined by a frequency or must be triggered by an event. For example, a manual task can be necessary after certain executions of a job.

Detailed Periodic Tasks

Oracle Database Periodic Optimization After some time of using SAP CC 4.0, it becomes possible and necessary to analyze and optimize the Oracle database tables/indexes of the specific users reserved for SAP CC. To ensure high level of performance with SAP CC, SAP AG recommends that you optimize the Oracle database usage by regularly launching the commands below.

They can be applied with the Core Database system and the BART Database system. Use the following requests to analyze and optimize the tables by estimating the statistics for a database schema:

CONNECT system/manager

EXEC dbms_stats.gather_schema_stats(ownname => '<schema name in

uppercase>', cascade => true, estimate_percent => 10, degree => 8);

ALTER SYTEM flush shared_pool;

The estimate_percent and degree parameters can be changed according to the accuracy of the estimation required and the degree of parallelism required, ideally set to twice the number of CPUs of the host.

Note that this estimation is only useful when the database has a considerable volume of data stored.

NOTE

The above procedure can be automated so that it is performed periodically (for example: monthly or weekly) during a specific low traffic period: This process will temporarily decrease the performances of the database and SAP CC 4.0.

Time Zones

SAP CC 4.0 does not manage time zones but it uses the local time of the host machines. All the hosts of the SAP CC landscape must have the same operating system time zone.

CAUTION

Once installed, do never change the OS time zone of the machines that host the components of SAP Convergent Charging.

Daylight Saving Time (DST) Updates

SAP CC 4.0 manages the DST (also called summertime) by using data provided by the SAP JVM. When DST rules are modified or created, you must update your landscape by updating all the JVM installations.

The SAP JVM includes both rules for daylight saving times and descriptions of global time zones in a unique container. For updating the DST rules, you have to update your landscape by applying the procedure outlined in SAP Note .

EXAMPLE

By default, SAPInst stores the SAP JVM for SAP CC in the folder:

<DRIVE>:\usr\sap\<SID>\SYS\exe\jvm\NTI386\sapjvm_6.1.010\ or /usr/sap/<SID>/SYS/exe/jvm/<OS_PLATFORM>/sapjvm_6.1.010/

Note that SAP Convergent Charging does not use the data related to descriptions of time zones as it does not manage time zones and uses only the local time of the hosts.

CAUTION

Changing the time zone of the host is not a possible workaround for a lake of DST rules. Contact first your SAP Support Team.

Allowances Purge Mechanism

When using the Allowances Management feature, it is necessary to regularly purge allowances from the back-end database in order to avoid latency and ensure the global performance of the system.

This purge mechanism can be executed:

Manually, using the start_purge_allowances command of the Admin+ user interface and specifying the following parameters:


A reference date, which is used to determine the list of expired allowances to remove

A maximum throughput, which corresponds to the maximum number of provider contracts per second that each Rater can consider during allowances purge operations, and thus control the impact of these operations on the global performance of the system

For further information about this command, refer to the SAP CC User Interfaces documentation

Automatically, using a dedicated scheduler which must be configured as described in the SAP

CC 4.0 Configuration Guide documentation

Both manual and scheduled executions of the purge operations log the following information when starting and stopping:

The number of provider contracts whose allowances have been successfully purged The number of provider contracts containing allowances which could not be purged The number of allowances successfully purged in contracts

NOTE

In addition to the log information, the following indicators are available to get the reference dates of the last manual or scheduled purge operation:

ALLOWANCES_PURGE_LAST_TRIGGER ALLOWANCES_PURGE_SCHEDULER_LAST_TRIGGER

For further information about these indicators, refer to the SAP CC 4.0 System Parameter

Reference documentation.

Setup Change

Core Server If the initial business traffic increased a lot, you may need to add some rater instances of the Core Server to your production landscape. You have to follow the sizing guidelines to determine the instances you need to add. When installing a new instance on an existing or new host, the traffic for rating and charging services will be automatically reorganized with all the running rater instances.

You can also add other types of instances of the Core Server: Taxer, Guider, and Dispatcher.

Troubleshooting

In case of difficulties with the business traffic, you can explore two solutions:

Fine tune the existing platform Add instances and hosts to your landscape

Generated temporary technical data can be regularly removed if not needed anymore. The tasks to be performed for this purpose are listed in the above chapter , see page [ ].

Potential Outdated Technical Data

SAP CC System Description

Core Server The SAP CC Core Server System generates technical data files as output results of the business processes (rating, charging, rerating and refilling).

Core Server: Standard Landscape

SAP CC System Description Location

Core Server

Rater instances

The rater instances of the Core Server System generate voluminous charged item files and refill record files that must be transmitted to a third-party billing system.

Depending on the integration between the SAP CC Core Server system and this external system, these files can become outdated.

In a scenario with such an external system, you can consult the system configuration of the Core Server to determine if these files are automatically removed by SAP CC or if they should be regularly archived.

In the repository <WORKING_DIRECTORY>, the files are temporarily stored in the subfolders:

/CC_POSTPAID/

/CC_PREPAID/

The <WORKING_DIRECTORY> is a particular shared central repository defined at the installation time. See the Installation Guide for more details.

NOTES

The current system configuration may be different than the default configuration. Check the configurations of the rater instances of the SAP CC Core Server system.

Some voluminous error files may exist in these folders. Do not remove them. See the section, page [ ] for details about problems with charged item files or refill

record files.

Log Files

The log files produced by the SAP CC 4.0 Server Systems are not considered as outdated technical data. Their volume must be checked or monitored.

High availability applications allow you to maximize downtime security and minimize downtimes. You can achieve this objective controlling the growth of redundant data and by implementing suitable logic to control redundant systems.

At SAP AG, the focus on high availability (HA) is always directed at business applications and their related components. SAP relies on the high availability applications of partner products with regard to the components such as, the operating system, database, and hardware, which are mandatory for implementing the infrastructure.

NOTE

For more information, see on SAP Service Marketplace at: .

To gain competitive advantage, you must think of a collaborative business. This means integrating existing heterogeneous system landscapes to include business partners, customers, and suppliers. The responsibilities concerning the use of a high availability application should be divided between customers, partners, and SAP as described below:

Customer

Decision for and against high availability applications Operation of a high availability environment

Partner

Provisions for hardware, infrastructure, and high availability applications Implementation of a high availability application at customer using their own

technology or SAP technology

SAP

Supports and provides technologies to enable the implementation of partner high availability applications

No certification of high availability applications of individual partners

NOTE

For more information, see on SAP Service Marketplace at: .

The trend is towards open system architectures in which end-to-end business processes combined with Web services run on multiple distributed application components. Such environments demand high availability not only for single components, but also for entire scenarios.

NOTE

SAP AG, along with partners, has developed a range of high availability applications, which many customers have already in use. The applications you choose will vary according to your system landscape. Ensure that you discuss your plans with your SAP consultant and hardware partner before implementation.

https://service.sap.com/partners

Downtimes

Downtime defines the time during which you cannot use a system or a resource productively. Irrespective of how the SAP system landscape is defined (with or without a high availability application); a breakdown of one or several components always requires action. To cope with these exceptional situations, it is imperative to ensure that the necessary resources are available in the event of malfunctions, problems, queries, such as an SAP specialist or a network administrator.

There are two types of downtimes described in the following chapters:

Planned Downtimes Unplanned Downtimes

Planned Downtimes

Planned downtime is the time for scheduled maintenance and upgrade during which a system cannot be used for normal productive operations. This time is used for a variety of purposes so that a system can function optimally and reliably. Some of the possible causes of planned downtime are as follows:

Parameter change Update to Support Packages (SPs) or patches Hardware maintenance Landscape reorganization by adding/removing an instance (to the Core Server system) Upgrades to new releases of SAP application components, database or operating system Database reorganization Database backup Archiving of business data objects

Preparation You must:

Agree upon a planned downtime in close cooperation between the IT department and the respective departments. This is the only way of defining the timeframe for the necessary downtimes, without restrictions being placed on the way the application works. A low traffic period is preferable.

Inform all those involved in advance about the upcoming system downtime Keep the downtime as brief as possible

Possible Maintenance Actions The following table lists the possible changes in SAP systems and the downtimes, which can be planned in each case to rectify the problem:

.

Upgrade of SAP CC 3.0 to 4.0

Mandatory Mandatory You must plan a downtime period.

Unplanned Downtimes

Unplanned downtime is the time during which a system cannot be used for normal productive operations due to unforeseen failure in hardware or software components, or operator mistakes.

Unplanned downtime can be extremely costly to an organization. The source of unplanned downtime can be in any of the layers that make up the complete software and hardware environment:

Front-end and middleware services for connection to the web, including the Internet Transaction Server (ITS), the SAP Web Application Server (SAP Web AS), and the SAP Enterprise Portal.

SAP system services of the individual application components of the SAP Business Suite – such as the Business Warehouse (BW), Business-to-Business Procurement (BBP) – and the SAP kernel.

Underlying hardware and software services, such as the database services, network and operating system services, and various hardware services, including servers, disks, memory, and uninterruptible power supply (UPS).

The risk of unplanned downtimes occurring can be minimized by avoiding single point of failures (SPOFs) in a complex system landscape. For the different components in a complex system landscape, there are several ways of avoiding these SPOFs.

Single Point of Failure

No measures for avoiding unplanned downtimes specified in the following list are a safeguard against logical errors. You can only protect against logical errors by implementing the appropriate backup and recovery measures.

The following table provides a list of SAP CC components, their SPOFs, and their corresponding high availability setup.

HA Setup Change


Core Server It is possible to add some instances of the Core Server system to improve the high availability.

You have to determine the new instances to be added to the production landscape according to the sizing guidelines and just install and start these new instances:

Guider instances Rater instances Taxer instances


Data purging and archiving allows you to:

Transfer data from the database to a file system, in order to later move this data in another consistent and secure storage system

Possibly definitively delete this source data, to decrease the global database size and increase the performance of the system

CAUTION

The purge and archive functionalities are only available for Sybase ASE, Oracle, and MS SQL Server. They are not available for IBM DB2.

Core Server and Core Database

To keep a constant volume size for the database or to control its maximum size, it is necessary to purge some data. This purge can be periodical or not, automated or manual. A database that is too large can dramatically decrease the global performances of SAP CC.

You may want to define purge and/or archiving for:

Audit data

SAP CC stores audit information when the audit mode is on. No archiving mechanism is provided, but two commands of the Admin+ user interface give the possibility to purge the different data related to the Data Auditing feature. For further information about this purging mechanism, please refer below.

Allowances data

When the Allowances Management feature is used, SAP CC stores different information related to allowances. No archiving mechanism is provided, but it is possible to purge this data manually (using the Admin+ user interface) or automatically (using a dedicated scheduler). For further information about this purging mechanism, please refer below.

Idempotency management data

SAP CC stores information to ensure safe operation of either refilling services invocation or Web Services consumption. This data must be regularly purged to warranty high performances of the SAP CC system. Refer to the Periodic Tasks section in this guide. The old data is stored in the WS_IDEMPOTENCY table of the Core Database.

Technical data relating to job operations

SAP CC stores information about the execution of job operations performed via Web Services, such as the job status. This data is stored in the WS_JOB table of the Core Database, and must be regularly purged to ensure the global performance of the SAP CC system. For further information, refer to the Periodic Tasks section in this guide.

BART Server and BART Database

The following procedures enable the DBA to purge and archive outdated data (Consumption Detail Records). It is also explained how to reuse archived data. The purge can be periodical or not, automated or manual. The old data to be purged is stored in the CDR table of the database.

The archive period cannot be less than the retention period configured at installation time (see PARTITION_DAYS on the PARTITION_PURGE table). Consult the SAP CC Configuration Guide for more information.

Legal and local policy may also apply.

NOTES

Refer to the purge and archive tables in the database schema to know the current configuration of the purge and archive process.

You must be connected as DBA to your RDBMS to use the following procedures.

Sybase ASE The following table describes the procedures to use for configuring data purge and archive:

Procedure overview Description

MANAGE_ARCHIVE Use this procedure to copy the data to be purged into data files in a given directory.

NOTES

The archived partitions are removed from the database This procedure can also be used to remove data without archiving

them into data files (using the “purgeWithNoArchive” argument described below)

CAUTION

Do not use this procedure if the archived database is not stored on a safe storage system (SAN or local RAID1-5 drive)

The following arguments are required for the MANAGE_ARCHIVE procedure:






archiveDBName (varchar)

The following arguments are required for the IMPORT_ARCHIVE procedure:

fromDate (varchar) toDate (varchar) archiveDBName (varchar)

Depending on the configuration of your SAP CC systems, the volume of the logs can increase. You have to monitor their sizes and determine a policy for archiving all the logs produced.

Consult the section for details about the locations of these files; see [page ].

The Data Auditing feature gives the possibility to track the operations which are performed by users, and to record the before and/or after versions of the different master data impacted by these operations. Audit data are created according to the configuration of the AUDIT_ACTIVATION and AUDIT_OBJECT_ACTIVATION parameters, and all this data is stored in the following tables of the Core database:

USER_OPERATION OBJECT_CHANGE_LOG OBJECT_SNAPSHOT

As the activation of the Data Auditing feature can lead to a large number of recorded audit data, it may significantly impact the performance of the whole SAP CC system. As a consequence, we highly recommend to execute purging operations, using the following commands of the Admin+ program:

purge_user_operations, which gives the possibility to purge the data related to the execution of user operations, stored in the USER_OPERATION table

purge_object_change_logs, which gives the possibility to purge the data related to both the object change logs and their associated object snapshots, stored in the OBJECT_CHANGE_LOG and OBJECT_SNAPSHOT tables

NOTES

For further information about these commands, refer to the command-line help of the Admin+

user interface, or refer to the User Interfaces online documentation For further information about the Data Auditing feature, refer to the Application Help

documentation

Advanced Troubleshooting: Tracing

Using tracing assumes that a problem is already noticed by a log message, by a complaining user or by non-functioning services or functions of the SAP CC systems or by connected applications and systems. Tracing is an exceptional procedure performed or supervised by a support specialist.

A support specialist can use the information provided by the trace messages. These voluminous messages include information about the location of the failure inside the system.

You can increase temporarily the volume of trace messages and log messages recorded by the SAP system by changing online the trace severity threshold to PATH and the log severity thresholds to INFO.

CAUTION

Do not perform this procedure in a production system landscape without the supervision of SAP Support Team.

Preparations Determine the severity threshold for trace messages that is relevant for your issue: INFO or PATH Determine if additional tracing domains are expected to facilitate the investigations and the

troubleshooting. By default, you must deactivate these domains.

To check communication via the Web Services technical interfaces, you use the WS additional tracing domain.

To check data cache function or data lock function, you use the CACHE or LOCK additional tracing domain.

To check communication via the Web Services technical interfaces, you use the WS additional tracing domain.

Determine if you need traces from all the instances of the SAP CC system or just from certain types (rater, dispatcher, …)

Determine when to perform the procedure: Determine the period or the cause event that is relevant.

Refer to the System Parameter Reference documentation for more information.



Procedure Launch the and log on Retrieve and write down the current configuration information:

GUI and Other Tools

Errors and Exceptions

Core Server There are three types of errors or exceptions that can be generated when the SAP CC Core Server system encounters a problem, they can be signaled in three possible ways.

Problem Returned as an Exception to the Client Application

Saved in Server Logs

Client application side failure Never Never

The client application has to manage the generation of logs.

Business errors Always returned Nested exceptions and error messages give more information about the precise nature of the error/problem

Depends on API error type and on log settings.

The INFORM log level shows all errors.

Core Server side failure Always returned Depends on API error type and on log settings.

The INFORM log level shows all errors.

Exceptions are generated when an error occurs. An exception contains a description of the overall possible reason for the error. The exception can contain nested exceptions giving further details about the possible cause(s) of the error. Exceptions are described in the API Reference documentation (the ‘JavaDoc’).

NOTE

The Core Tool user interface and the BART Server system are client applications regarding to the Core Server system. They catch the errors and exceptions signaled by the Core Server system.

Core Tool The Core Tool user interface catches the exceptions signaled by the Core Server system and warns the power user.

Error Reason Codes

Core Server Error Reason Codes (for Non-Business Errors) The SAP CC Core Server system signals the non-business errors with one single class of error message: serverFailureException.

The INFORM log level is used when you are using SAP CC in production. This allows best performance speed (fewer log lines written) and only signals serious errors, potential bugs or malfunctions. If you

encounter errors or problems with your system, you can increase the log level to DEBUG, however this configuration reduces performance.

The table below details reason codes and their possible cause:

Reason Code Description

ACCESS_COMPATIBILITY_FAILURE Reason code for old use of access (in subscription).

CACHE_INVALIDATION_FAILURE Reason code when the updater did not succeed to update in a synchronous way, the caches belonging to rating instances.

CANNOT_LOCK_RESOURCE Reason code when the Core Server cannot lock resources into the database after having tried SQLHELPER_MAX_REDO attempts.

DATABASE_FAILOVER Reason code when the Core Server is failing over due to a database failure.

DATABASE_FAILURE Reason code when a failure occurred with the database.

HCI_CONCURRENCY_OPERATION Reason code relative to a service invocation on HCI APIs which is in concurrency with another.

HCI_SERVICE_VIOLATION_PROTOCOL Reason code when XML stream received by the HCI servers (updater and dispatcher) is not conformed to the HCI protocol.

HCI_UNSUPPORTED_SERVICE Reason code relative to a service invocation on HCI APIs which is not supported.

INCOMPATIBLE_CONFIGURATION Reason code when the Core Server cannot load its configuration due to out of rank parameter values or missing parameter values.

INTER_INSTANCE_COMMUNICATION_FAILURE Reason code for networking/communication issues between rater or updater instances of the Core Server.

IO_FAILURE Reason code when the Core Server encountered some IO failure.

MESSAGE_QUEUE_FULL Reason code relative to fulfilling of queues implemented by message protocol.

MESSAGE_UNSUPPORTED_SERVICE Reason code relative to a service invocation on message APIs which is not supported.

OFFER_CACHE_BUSY_WHILE_REFRESHING Reason code when the subscription cannot be charged because its related offer is temporary inaccessible due to cache refreshing process.

SERVER_SHUTTING_DOWN Reason code when the Core Server is shutting down.

Reason Code Description

SERVER_TIMEOUT_OCCURED Reason code when the Core Server cannot execute the API with the required timeout.

SERVER_TO_CLIENT_COMMUNICATION_FAILURE The server encountered communication or network issues while trying to reply to the client.

SLEEPING_BULK_LOADER Reason code when the backup rejects a rating request due to the restarting of the original rater regarding the partition ID.

STATEFUL_SERVICE_VIOLATION_PROTOCOL The message sent to the stateful API is not conformed to the stateful protocol.

STATELESS_SERVICE_VIOLATION_PROTOCOL The message sent to the stateless API is not conformed to the stateless protocol.

SWITCH_BACK_TO_RATER Reason code when the backup rejects a rating request due to the restarting of the original rater regarding the partition ID.

TAX_CACHE_BUSY_WHILE_REFRESHING Reason code when the subscription cannot be charged because taxes are temporary inaccessible due to cache refreshing process.

UNSUPPORTED_FAILURE Reason code when the Core Server failure is unknown or not supported.

UNSUPPORTED_JAVA_FAILURE Reason code when the Core Server failure is a Java error and is not supported.

When a non-business error occurs in the server system, consult the serverFailureException in the API Reference for an up-to-date list and an indication of the possible cause(s). You can find this reference from the SDK of SAP CC or in SAP Help Portal at the following location:

Charged Item Files Partially or Not Loaded in SAP ERP/FI-CA

Description

Symptom There are some data files with the file extensions ‘.err.zip’ or ‘.err.csv’ remaining in the folders of the bulkloader instances of the SAP CC Core Server system.

Possible reason

They include charged items that have not been converted in billable items and then loaded in the SAP ERP/FI-CA System for the billing and invoicing functions.

Description

Possible resolution

The error messages are loaded into corresponding control files. Open these control files and try to solve the problems (connection lost with SAP ERP System, invalid billable items).

When the problems are solved, it is necessary to change manually the file extension to ‘.arc.zip’ or ‘.arc.csv’. The Core Server will automatically try to load again the files into SAP ERP.
