How to get a transaction dump.
If you get a request from Ideal Support to send a transaction dump because of an Abend, you first want to make sure the Abend is in the list of transactions that will cause the dump.
To see the list of transactions in CICS:
CEMT S TRD stands for CEMT SET TRDUMPCODE
CEMT I TRD stands for CEMT INQUIRE TRDUMPCODE
