Conventions used in this guideAll probe guides use standard conventions for operating system-dependentenvironment variables and directory paths.

Operating system-dependent variables and paths

All probe guides use standard conventions for specifying environment variablesand describing directory paths, depending on what operating systems the probe issupported on.

For probes supported on UNIX and Linux operating systems, probe guides use thestandard UNIX conventions such as $variable for environment variables andforward slashes (/) in directory paths. For example:

$OMNIHOME/probes

For probes supported only on Windows operating systems, probe guides use thestandard Windows conventions such as %variable% for environment variables andbackward slashes (\) in directory paths. For example:

%OMNIHOME%\probes

For probes supported on UNIX, Linux, and Windows operating systems, probeguides use the standard UNIX conventions for specifying environment variablesand describing directory paths. When using the Windows command line withthese probes, replace the UNIX conventions used in the guide with Windowsconventions. If you are using the bash shell on a Windows system, you can use theUNIX conventions.

Note: The names of environment variables are not always the same in Windowsand UNIX environments. For example, %TEMP% in Windows environments isequivalent to $TMPDIR in UNIX and Linux environments. Where such variables aredescribed in the guide, both the UNIX and Windows conventions will be used.

Operating system-specific directory names

Where Tivoli Netcool/OMNIbus files are identified as located within an archdirectory under NCHOME or OMNIHOME, arch is a variable that represents youroperating system directory. For example:

$OMNIHOME/probes/arch

The following table lists the directory names used for each operating system.

Note: This probe may not support all of the operating systems specified in thetable.

3. Configuring the probe.This guide contains details of the essential configuration required to run thisprobe. It combines topics that are common to all probes and topics that arepeculiar to this probe. For details about additional configuration that iscommon to all probes, see the IBM Tivoli Netcool/OMNIbus Probe and GatewayGuide.

Firewall considerationsWhen using CORBA probes in conjunction with a firewall, the firewall must beconfigured so that the probe can connect to the target system.

Most CORBA probes can act as both a server (listening for connections from thetarget system) and a client (connecting to the port on the target system to whichthe system writes events). If you are using the probe in conjunction with a firewall,you must add the appropriate firewall rules to enable this dual behavior.

There are three possible firewall protection scenarios, for which you mustdetermine port numbers before adding firewall rules:1. If the host on which the probe is running is behind a firewall, you must

determine what remote host and port number the probe will connect to.2. If the host on which the target system is running is behind a firewall, you must

determine the incoming port on which the probe will listen and to which thetarget system will connect.

3. If each host is secured with its own firewall, you must determine the followingfour ports:a. The outgoing port (or port range) for the probe.b. The hostname and port of the target system.c. The outgoing port on which the target system sends events if the probe is

running as a client.d. The incoming port on which the probe listens for incoming events.

Note: Most, but not all, CORBA probes listen on the port specified by theORBLocalPort property. The default value for this property is 0, which means thatan available port is selected at random. If the probe is behind a firewall, the valueof the ORBLocalPort property must be specified as a fixed port number.

CORBA probes that use EventManager or NotificationManager objects may usedifferent hosts and ports from those that use NamingService and EntryPointobjects. If the probe is configured to get object references from a NamingService orEntryPoint object, you must obtain the host and port information from the systemadministrator of the target system. When you have this information, you can addthe appropriate firewall rules.

Data acquisitionEach probe uses a different method to acquire data. Which method the probe usesdepends on the target system from which it receives data.

The probe gathers alarms from Nokia-Siemens NetAct using a CORBA 3GPPinterface.

Data acquisition is described in the following topics:v “Connecting to the CORBA interface”v “IRP Agent status” on page 5v “Filtering notifications and alarms” on page 5v “Lookup table” on page 7v “Command line interface” on page 8v “Peer-to-peer failover functionality” on page 9

Connecting to the CORBA interfaceThe probe acts as an Integration Reference Point (IRP) Manager and connects tothe Nokia-Siemens NetAct system using a CORBA 3GPP interface.

The AlarmIRPOperation and NotificationIRPOperation points form a part of theIRP Agent to which the probe connects.

The probe uses one of the following methods to make a connection:v Interoperable Object Reference (IOR) filesv Naming Service

Using IOR files

When using IOR files, the probe gets the object reference of the AlarmIrpName andNotificationIrpName objects from the Interoperable Object Reference (IOR) filesspecified in the AlarmIrpFile and NotificationIrpFile properties.

Set the AlarmIrpName property to the name used to resolve the Alarm IRP in theNaming Service and set the NotificationIrpName property to the name used toresolve the Notification IRP in the Naming Service.

Using a Naming Service

If the AlarmIrpFile and NotificationIrpFile properties are not specified, theprobe gets the object references of the AlarmIRPOperation andNotificationIRPOperation points from the Naming Service.

The probe gets the Naming Service IOR file from the server specified by theNetActServerName property (using the port specified by the NetActServerPortproperty and the command specified by the NamingServiceIorRequest property).

The Naming Service uses the values specified by the AlarmIrpName andNotificationIrpName properties to resolve the Alarm IRP and Notification IRPpoints.

Page 15: IBM Tivoli Netcool/OMNIbus Probe for Nokia-Siemens NetAct ... · PDF fileIBM ®Tivoli Netcool/OMNIbus Probe for Nokia-Siemens NetAct 3GPPV4 (CORBA) Version 10.0 Reference Guide March

IRP Agent statusThe probe checks the status of the IRP Agent every 60 seconds.

You can use the Agentheartbeat property to change the frequency with which theprobe checks the status of the IRP Agent.

Filtering notifications and alarmsThis topic contains information about how to enable the retrieval of notificationsand alarms from the target system.

The NotificationFilter and AlarmFilter properties allow you to specify thenotifications and alarms that the probe receives from the target device.

When you use these properties, you must use the actual token names. Forexample, the token h represents the element NV_PERCEIVED_SEVERITY. So to specifythat the probe is only sent notifications with a perceived severity of 3, set theNotificationFilter property to $h == 3.

You can specify more complex filters using AND, OR, and NOT statements. Forexample, to specify that the probe is sent notifications with a perceived severity of3 or 4, set the NotificationFilter property to the following value:

($h == 3) OR ($h == 4)

The following table lists the token/element mappings available for the AlarmFilterand NotificationFilter properties:

3. (alarmType < ENVIRONMENTAL_ALARM)

Lookup tableThe probe is supplied with a lookup table that contains details of the various typesof alarms that Nokia-Siemens NetAct generates.

At installation, the Corba_3gpp_V430.lookup file supplied with the probeinstallation package is installed to the following location:

$OMNIHOME/probes/includes/

The following line in the rules file references the lookup file:

include "../includes/Corba_3gpp_V430.lookup"

Note: The include command assumes that the probe is run from the standard$OMNIHOME/probes/ directory. If you are running the probe from a differentdirectory, replace “..” with the absolute directory path to the lookup file. Do notuse the $OMNIHOME environment variable in this directory path.

In this section of the rules file, you must also specify which version ofNokia-Siemens Operations Support System (OSS) the probe is running against:v For OSS4, specify $Version = "OSS4"

v For OSS3 and all previous versions, specify $Version = "OSS3"

Command line interfaceThe probe is supplied with a Command Line Interface (CLI). This interface enablesyou to execute commands to acknowledge and unacknowledge alarms.

To use the CLI, you must use the CommandPort property to specify a port throughwhich commands will be sent. The default port is 6970. When you want to issuecommands, use Telnet to connect through this port. You can use theCommandPortLimit property to limit the number of Telnet connections that theprobe can make at one time.

The following table lists the commands that you can use with the CLI:

Table 7. CLI commands

Command Description

acknowledge_alarm alarm_id This command allows you to acknowledge analarm in the 3GPP interface.

This command takes the NV_ALARM_ID identifier asa parameter. Only one alarm can beacknowledged at a time.

Before using this command, you must specify avalue for the AckSystemId property.

exit/quit This command closes the connection.

help This command displays online help about theCLI.

unacknowledge_alarm This command allows you to unacknowledge analarm in the 3GPP interface.

Note: This command is not currently supportedby Nokia-Siemens NetAct.

userid_acknowledge_alarm alarm_iduser_id

Use this command to acknowledge an alarm inthe CORBA interface by specifying the alarm ID(NV_ALARM_ID) and the user ID (NV_ACK_USER_ID)of the user acknowledging the alarm.

Before using this command, you must specify avalue for the AckSystemId and AckUserIdproperties.

userid_unacknowledge_alarm alarm_iduser_id

Use this command to unacknowledge an alarm inthe CORBA interface by specifying the alarm ID(NV_ALARM_ID) and the user ID (NV_ACK_USER_ID)of the user acknowledging the alarm.

Before using this command, you must specify avalue for the AckSystemId and AckUserIdproperties.

version This command displays the version of the probe.

CLI scripts

Because the CLI uses Telnet connections, you can connect to the probe fromanywhere by creating a desktop tool to open a Telnet connection, send a command,and then close the connection. This means that simple scripts can be set up toallow users to acknowledge selected events from the IBM Tivoli Netcool/OMNIbus

event list.

Peer-to-peer failover functionalityThe probe supports failover configurations where two probes run simultaneously.One probe acts as the master probe, sending events to the ObjectServer; the otheracts as the slave probe on standby. If the master probe fails, the slave probeactivates.

While the slave probe receives heartbeats from the master probe, it does notforward events to the ObjectServer. If the master shuts down, the slave probe stopsreceiving heartbeats from the master and any events it receives thereafter areforwarded to the ObjectServer on behalf of the master probe. When the master isrunning again, the slave continues to receive events, but no longer sends them tothe ObjectServer.

Example property file settings for peer-to-peer failover

You set the peer-to-peer failover mode in the properties files of the master andslave probes. The settings differ for a master probe and slave probe.

Note: In the examples, make sure to use the full path for the property value. Inother words replace $OMNIHOME with the full path. For example:/opt/IBM/tivoli/netcool.

The following example shows the peer-to-peer settings from the properties file of amaster probe:Server : "NCOMS"RulesFile : "master_rules_file"MessageLog : "master_log_file"PeerHost : "slave_hostname"PeerPort : 5555 # [communication port between master and slave probe]Mode : "master"PidFile : "$OMNIHOME/var/opc_ua"

The following example shows the peer-to-peer settings from the properties file ofthe corresponding slave probe:Server : "NCOMS"RulesFile : "slave_rules_file"MessageLog : "slave_log_file"PeerHost : "master_hostname"PeerPort : 5555 # [communication port between master and slave probe]Mode : "slave"PidFile : "$OMNIHOME/var/opc_ua2"

Running the probeBefore running the probe for the first time, you must specify a minimum set ofproperties.

Depending on which method you use to connect to the CORBA 3GPP interface,you must specify values for the some of the following properties before runningthe probe:v AlarmIrpFile

v NetActServerName

v NotificationIrpFile

For more information about these properties, see “Connecting to the CORBAinterface” on page 4.

Use the following command to start the probe:

$OMNIHOME/probes/nco_p_nokia_netact_3gpp

Running multiple probes

You can run multiple instances of the probe on the same machine. For eachinstance, specify a different port to which the server listens using the ORBLocalportproperty and specify a unique instance identifier using the InstanceId property.

Shutting down the probe

To stop an instance of the probe, issue a stop signal to the process associated withthat probe instance.

TroubleshootingVarious issues arise as users work with the probe. This troubleshooting informationis provided to help you diagnose and resolve such issues.

IOR FileNotFound exception in the log file

The probe is running properly but the following error message appears in the logfile:

Error: Failed to retrieve old probe-IOR: java.io.FileNotFoundException:/tmp/NetcoolIRPManager.ior (No such file or directory)

This issue arises because the IOR file is not available in the expected location thefirst time the probe looks for it, but it is detected subsequently.

For example, if you specify a value of Nokia_Netact_R4_3 for the InstanceIdproperty, the probe will look for the following file in the /tmp directory on startup:

Nokia_Netact_R4_3_NetcoolIRPManager.ior

This file will not be available in this location the first time that you run the probe,so the probe throws the error described above. The probe then continues toconnect to the Nokia-Siemens NetAct server and subsequently creates the IOR filein the /tmp directory. The next time that the probe is started, it will detect the IORfile in this directory.
