Solution

The ZDC log file is only used for internal debugging at the request of support and development.

It's disabled by default: LOG_INITIAL(CLOSED).

Suggest deleting or commenting out the IDCAMS step (ZDCMEPCA) to avoid the error messages.

***********************************************************************
** **
** LOG PARAMETERS **
** **
** zDC contains an extensive logging facility uses normally **
** only for debugging program errors. Compuware support **
** personnel may ask you to enable the logging facility to **
** help them find an error with the zDC code. **
** **
** If these parameters are omitted, then there is no logging **
** active in this zDC and there is no overhead associated **
** with the log facility. If you enable logging, the CPU **
** usage of the zDC region may increase a little but care **
** has been taken to insure that the log does not cause any **
** significant performance impact to zDC itself. **
