EQA9945S z/OS® Debugger DTRCB Unavailable.

Explanation
The z/OS Debugger non-Language Environment®
CICS® global user exits were made active in a CICS region where z/OS Debugger did not successfully initialize during CICS region
startup.

Programmer response
Ensure that Language
Environment is installed in the
CICS region and verify that the z/OS Debugger installation steps were executed properly. For
example, the z/OS Debugger
hlq.SEQAMOD data set is in the DFHRPL DD and that the
hlq.SEQASAMP(EQACCSD) job was run to add z/OS Debugger resource definitions to the CICS region.
