Hello all.

I am trying to develop a synchronous data capture exit (DCE) in an effort to gather updates being made on our IMS database and initiate a process to apply them to a new DB2 database. Currently the exit is defined on two segments. The DBA group has completed the DBD definitions and setup the psb and transaction that i will be using.

I am currently trying to test this via a BMP. The assumption was being made that the DCE would be picked up by IMS via the concatenation list within the IMS region.

If I don't reference the steplib where my load for the DCE resides in my job's concatenation list I take a U3314 abend and get message DFS3311I indicating my exit is not found.

If I reference the steplib where my load for the DCE resides in my job's concatenation list I take a U4038 abend and get message IGZ0168S regarding me attempting to create second enclave within a reusable environment.

I am not sure what I am missing here. Any help would be appreciated

Peter,
We looked at that option, but there is one comment listed with the documentation that suggests it is not a good idea with IMS -
"IMS™ consideration — RTEREUS is not recommended for use under IMS."

I don't know if it could be any help, but there was a fairly recent discussion of IMS with RTEREUS on IBM's COBOL Cafe.
