Storing DTCN debug profiles in a VSAM file

By default, the CICS® DTCN transaction stores its debugging profiles into a CICS temporary storage queue (TSQ) called EQADTCN2. Because CICS destroys temporary storage queues at region termination, any profiles stored in EQADTCN2 are deleted when a region is stopped. To save debugging profiles across region termination and restart or after the owning terminal is disconnected, store the profiles into a VSAM data set.

Do the following steps to instruct DTCN to store its debugging profiles in a VSAM data set:

1. Create the VSAM data set by following the instructions in the EQAWCRVS member of the hlq.SEQASAMP data set.
2. Modify the CICS region startup JCL so that the EQADPFMB DD statement identifies the VSAM data set you created in step 1.
3. Define the VSAM file to the CICS region by following the instructions in the EQACCSD member of the hlq.SEQASAMP data set. Sharing DTCN debug profile repository among CICS systems also describes examples of CICS resource definitions.
