To extend use of existing CICS applications into new programming paradigms

• WebSphere MQ/BI• Application Integration

Why would customers use CICS BEP? To re-use existing applications through events to drive new business process and utilize new technology

•quickly•without changes to existing application code

Mainframe still the backbone of many business today - there are still a lot of important applications residing on these systems

IBM Software Group


Application Integration

Event driven processes allow for a new non evasive way of integrating applicationsThe Event the result of an application Action can be easily extracted for use in different or modern applicationsProvides a non-intrusive way to have legacy applications exploit new technology e.g. Web, mobile etc.Re-use of legacy applications in modern business environments ‘has just got a lot easier’! Application Integration can now be a reality for legacy applications

Scenarios: Improved Customer Service; BankingCustomer Pain

The bank’s customers are unaware when they are about to go overdrawn and therefore incur banking charges and interest charges when they go into the red

The SolutionThe bank’s retail and business customers have accounts that are managed by CICS. With CICS BEP, the bank can now offer a service whereby customers can be contacted by text message to their cell phones, when their account reaches a certain level – for example $0. The customers themselves decide on what this rule should be. CICS BEP monitors the account balance and as soon it reaches £0 (or £10 or whatever) an MQ message is generated, and sent to a telephony integration broker. This creates an SMS message which is then sent to the customer’s cell phone.

The BenefitsInstant notification of account balance enabling customers to remedy any out of line balances before charges are applied. More satisfied customers who are less likely to move to another bank in the extremely competitive banking sector.

IBM Software Group


Scenarios: Improved Hospital Efficiency; HealthcareCustomer Pain

A Hospital was struggling with effectively managing the number of patients every day. Administration costs were high and customer satisfaction was at an all time low due to the average waiting time between the various different departments that patients had to visit in one day.

The SolutionCICS Business Event Publisher takes customer information and records from CICS and publishes the details into MQ. Customers who have to have a blood test, X-Ray and Checkup all in one day can have their records published in different formats. Processes can also be automated so that as soon as a doctor in one department has finished with a patient the records and results are sent on to the next department where the customers name is instantly added to the waiting list before he/she even gets there. On arrival the customer can see exactly where they are in the queue as it is published on a screen (included estimated waiting time). The customer is happy as they are moved through the system quicker, and the doctors have to spend less time on administration.

The BenefitsImproved processes, Less margin for error, Better service to customers, less administration increased customer satisfaction, , increased flexibility, leverages existing infrastructure and investment, based on the industry defacto standard for messaging.

IBM Software Group


Scenarios: Improved Customer Support; IT organization, any Industry

Customer PainIT manager and his staff are hearing about errors occurring with CICS applications too late. This results in lengthy application downtime and dissatisfied users

The SolutionAll application errors are detected by a unique program which is linked to all other application programs. CICS BEP evaluates all the Exec CICS Link commands in order to understand if the command has been issued for an application error. A "filter" CICS BEP exit routine is developed so that an "alarm message" is written to 2 MQ queues only if a given threshold of errors in a given time interval is exceeded. The first queue is then read by a, that sends the message to an "alarm console" and the second is read by computer/telephony integration layer which sends a SMS message to a specified cell phone. All these parameters (error codes, threshold, alarm and SMS messages, time interval, cellular number and so on) are defined in CICS BEP’s rules engine and the MQ messages through the CICS BEP administration workstation so that they can easily modified and tuned without any programming effort.

The BenefitsInstant notification of errors in CICS applications, both at the alarm console and on cell phone(s). Less application downtime, more satisfied users

IBM Software Group


Scenarios: Improved Operational EfficiencyStock Control, ManufacturingCustomer Pain

Inventory of parts in a car manufacturing process are not keeping up with demand – result is reduced production, lost orders, dissatisfied customers, lost business.

The SolutionInventory of parts and orders received are managed by two CICS applications. CICS BEP is deployed to monitor the number of cars on order, and compare it with the level of parts inventory. If the number of cars to be delivered within a specified timeframe indicates that the parts inventory will be exceeded in the near future, CICS BEP recognises that event as exceptional. When the level of under supply reaches a minimum predefined level, CICS BEP generates an MQ message which takes the form of an order, which is sent to the appropriate supplier via the business to business systems that have been established between the car manufacturer and its suppliers.

The BenefitsInstant conversion of a depleted parts inventory situation into an order for resupply. No disruption to production process, less orders lost due to delayed delivery

Convert Old Unsupported Cobol Code to LEWith

Debug Tool Utilities AF V4 converter, CCCA

IBM Software Group


What Debug Tool Converter (CCCA) does:

Cobol and CICS Command Level Conversion Aid

Helps you convert old Cobol source:

• To Cobol 85 Standard Language

• Language Environment (LE)

IBM Software Group


How does Debug Tool Converter (CCCA) work

CCCA is an interactive system comprising ISPF panels

that enable you to access a batch (MVS) or foreground

Conversion application to:

• Define the type of conversion you want

• Submit a batch job (MVS), or run CCCA in foreground

to convert your source program

COBOL Source ConversionOldBOL to NewBOL

OS/VS COBOL had LOTS of undocumented extensions

85 Standard or 2002 Standard COBOL?We didn’t wait until 2002 to OO COBOL!

We will also support the new standard in the future

IBM COBOL Conversion Aid: continuous improvementKnown as CCCA, Earlier version was: 5785-ABJ

Over 80 user requirements added in Version 1 Release 2

CCCA Version 2 shipped in June 1998Additional improvements

Debug Tool Utilities AF V4 5655-L23, includes CCCA

IBM Software Group


IBM Software Group


What about compiler compatibility?Once you have programs that are 1985 standard you can change compilers at any time.

VS COBOL II NOCMPR2

COBOL for MVS & VM NOCMPR2

COBOL for OS/390 & VM NOCMPR2

Enterprise COBOL

You can compile any existing programs at any time with newer compiler and get the same results!

Migrate gradually at service/update time

IBM Software Group


IBM Software Group


IBM Software Group


Official DisclaimerHow long can you safely continue to run your OS/VS COBOL applications

without a newer library is difficult to predict.

As long as nothing in your environment changes, you can generally continue to run your OS/VS COBOL programs. However, if you change any other software in your environment, you could break any or all of your existing OS/VS COBOL applications

A perfect example of this was DFSMS/MVS V1R3. The VSAM component changed in such a way that a problem in the OS/VS COBOL library routine ILBOVOC was resulted. This problem is fixed in Language Environment for MVS & VM R5 but still exists in OS/VS COBOL. A future release of VSAM could again break all OS/VS COBOL programs in your shop.

This COBOL problem is tolerated in DFSMS R3 via DFSMS APAR OW19233.

IBM Migration Utility for z/OSCommon QuestionsQ1: Are there Easytrieve Plus programs that can't be converted? A1: Not so far! Some may require changes to the Easytrieve source for COBOL compatibility but none were found "unconvertible".

Q2: Do I need to keep my CA-Easytrieve Plus license? A2: No - once you've validated that the converted COBOL produces the same result, you have no further need for this license. You can even write new programs in Easytrieve Plus syntax and convert them with the IMU, so long as you retain your IMU license.

Q3: Can the Migration Utility handle "classic" Easytrieve? A3: As it stands today, the Migration Utility works with Easytrieve Plus. However, IBM is looking for a partner to work with on support for "classic" Easytrieve.

Q4: How quickly can my programs be converted? A4: This depends on the number of programs and the amount of resource available, but 1,000 to 2,000 over 3-4 months is reasonable; up to 5,000 within 5-6 months is also feasible.

Q5: What are some large scale examples of successful migrations?A5: 1. Large US Information Services and Publishing company - 2600 jobs in 3 months (8/2003);

2. Large US Office Supply Retailer - 4350 jobs in 6 mo. - incl. automation tools devel. (5/2003);3. Large Midwestern University - 200 jobs in 45 days (5/2002)

IBM Software Group


IBM Migration Utility for z/OSCommon Questions (Continued)Q6: How can we tell how many programs we have? A6: Since we have so many, we aren't sure! Use of the new Discovery Utility can help locate Easytrieve programs

Q7: How can we efficiently run the conversion of my CA-Easytrieve Plus programs? A7: The new Mass Conversion Utility is a batch program that automatically "feeds" a list of programs to the IMU for conversion.

Q8: What is the expected (average) accuracy of conversions to COBOL? A8: With recent improvements in syntax-handling, most customers are seeing 90 to 98% accuracy without changing any Easytrieve code.

Q9: How can we efficiently test the programs once they are converted? A9: Most programs can be run in a parallel test mode with the new Parallel Test Utility, which submits jobs in both Easytrieve Plus mode and in the converted COBOL, capturing the results.

Q10: Once parallel test jobs have been run, is there any way to automatically compare the outputs? A10: Once the outputs have been captured, the Automatic Comparison Utility can be used to validate the results of most converted programs.re there Easytrieve
