(ZOS) 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 the local WAS to existing unchanged IMS transactions. For this support, optimized local adapters uses the IMS Open Transaction Manager Access callable interface (OTMA C/I).

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


Tasks

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 WAS 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 WAS, the calls are terminated with the error, Abend S-F92.

We have activated support for the optimized local adapters so that the WAS applications can begin calling existing unchanged locally running IMS transactions.
