MVS LNKLST Concatenation

Informatica strongly recommends against including the PowerExchange load libraries in the MVS LNKLST concatenation as unexpected job abends can occur. For example, IMS jobs that start prior to the PowerExchange Logger and PowerExchange Agent address spaces initializing may fail.

If the PowerExchange hlq
.LOAD and hlq
.CRG.LOAD libraries are included in the LNKLST concatenation, then:

You must include the IMS RESLIB and it must be included after hlq
.CRG.LOAD.

The library containing EDMSDIR must be included.

EDMSDIR should specify the option CCERR=CONT as access to any IMS database causes PowerExchange software to get control. If CCERR=ABEND is coded in EDMSDIR, access fails if the PowerExchange Agent is not active.

Source for EDMSDIR is supplied in member SETUPAGT in the hlq
.RUNLIB library. Change and rerun this job if changing the CCERR parameter is necessary. To use CCERR=ABEND, add the EDMPARMS DD in any batch job that updates IMS files to be captured.

If you have added the hlq
.LOAD library to the LNKLST concatenation, you can stop an ECCR from capturing changes for a specific job by including the following DD statement:

//EDMNOCAP DD DUMMY
