Enabling optimized local adapters over OTMA/IMS support

The WebSphere® Application Server for z/OS® optimized local adapters support has Information Management System (IMS™)-specific installation and setup requirements. Use this task to prepare your IMS environment to make outbound calls from applications deployed on your local WebSphere Application Server to existing unchanged IMS transactions. For this support, optimized local adapters uses the IMS Open Transaction Manager Access callable interface (OTMA C/I).

Before you begin

If you need more information about IMS, see the IMS product information center.

About this task

Procedure

Activate the IMS OTMA callable interface initialization program. Use the following procedure to activate the OTMA C/I SVCs. This must start after an IPL of the system, where IMS and WebSphere Application Server are running.
//* Sample job to install/activate OTMA C/I SVC 
//OTMASVCI EXEC PGM=DFSYSVI0,REGION=4M 
//STEPLIB DD DSN=<IMS-HLQ>.SDFSRESL,DISP=SHR  
//SYSPRINT DD SYSOUT=*  
//SYSUDUMP DD SYSOUT=* 
If this process is not started before calls to IMS programs begin in WebSphere Application Server, the calls are terminated with the error, Abend S-F92.

Results

You have activated support for the optimized local adapters so that the WebSphere Application Server applications can begin calling existing unchanged locally running IMS transactions.
