DRA SDUMP output

The DRA creates a dump when a DRA request fails or when DRA processing fails. The DRA first tries to create a z/OS® SDUMP.

DRA SDUMP output contains:

IMS control region
DLISAS address space
Key 0 and key 7 CSA
Selected parts of DRA private storage, including the address space control block (ASCB), task control block (TCB), and request blocks (RBs)

A DRA SDUMP has its own SDUMP option list. To add to the SDUMP option list of a DRA, you can use the CHNGDUMP parameter. However, you cannot use the CHNGDUMP parameter to delete areas from the list.

You can format the IMS control blocks by using the Offline Dump Formatter (ODF). The ODF does not format DRA storage. You can use IPCS to format the z/OS blocks in the private storage of the CCTL.
