To use IMS OTMA, your system must meet certain minimum requirements such as the IMS version, IMS startup parameters, XCF group name, OTMA initialization after a z/OS IPL, and RACF resource definition. Check with your systems programmer and systems administrator for details and set up.
The communications between the TIBCO Object Service Broker OTMA Callable Interface and IMS OTMA is synchronous, therefore an interpreter TCB is held while waiting for a response.
The return code and reason codes are stored in the map table; refer to @OTMA_MAP in
TIBCO Object Service Broker Shareable Tools for details. You can check these codes in your rules. You can find a complete description of the return codes and reason codes in the IBM manual,
IMS Open Transaction Manager Access Guide and Reference, SC26-9434.
