CICS Transaction Server

Maintenance, Repurposing, or Modernization

Qualifying a Training Request

Organizations with a longstanding and substantial investment in CICS Transaction Server have inquired about specialized training which will provide instruction on:

Maintenance Programming	SOA: Service Oriented Architecture	Application Development
In order to update and debug CICS applications.	The process and steps involved in application and platform migration.	CICS web enablement with the Java language and third party software.

SYS-ED provides industry-standard and tailored courses for efficiently serving data to multiple groups of internal and external users and address slow response time due to screen scraping overhead.

For example, programs can be used for screen scraping, multiple and single API's, and support for green screen and non-green screen applications.

Controlling Long Query Transactions

In order to provide a terminal user with the ability to obtain the status or abort a lengthy inquiry, a query can be designed as a separate task to communicate with the terminal user. The terminal task writes a record to transient data identifying the terminal id and the query to be started. It can then issue an "EXEC CICS DELAY" with an interval equal to the maximum time that the user will be made to wait and both a REQID and TERMID.

The transient data queue should have a trigger level of one to begin processing the query request. When complete, it writes the results back in a temporary storage record which includes the TERMID as part of the QUEUE and cancels the wait of the original task. The original task, after issuing its wait, reads the temporary storage record.

If not found, it instructs the user that the query is in progress and asks whether to wait.
If the user does not want to wait, the terminal task is ended.

Another transaction can be used to check the query at a later point by attempting to read the temporary storage record.

If the answer is yes, the temporary storage record is reread in order to ascertain whether the query has completed.
If the answer is no, the user terminal goes back into the wait state.

IBM Rational Developer for System z

Implementation of a service oriented architecture provides for the reuse of applications to reduce development costs. CETi Technology Partners are experienced with the design and coding for data sharing and flexibility in the service oriented architecture architectures supported by IBM system software.

IBM Rational Developer for System z can be used to:

1- Modernize, streamline, and replace outdated 1970’s green screen technology.

2- Provide structured, efficient analysis, editing and testing operations.

Program maintenance can then be performed using Eclipse-based tools.

Examples and Exercises

The CICS Transaction Server examples and exercises will be tailored to the client's operational objectives:

1- Printing documents to remote printers; this includes devices on a TCP/IP network using a CICS destination queue.

2- The utilization of TS: Transaction Server and TD: Transient Data queues for determining transaction status and terminating a transaction.

3- Passing large amounts of data to another program using channels and containers.

4- Coding programs which allow CICS Transaction Server applications to communicate using the SOAP: Simple Object Access Protocol. Transports can be provided over HTTP: Hypertext Transfer Protocol and WebSphere MQ.

5- Coding a Java application under CICS. CICS Transaction Server 4.2 supports IBM’s 64-bit JVM; this makes it easier to accommodate storage-consuming Java applications.

6- Developing an application that uses VSAM alternate indexes to browse a VSAM dataset.

CICS Transaction Server and interrelated information technology subject matter can be researched using the course search engine.
