Description:

I am providing an IPCS dump to CA to analyze. My CA Datacom Multi-User (MUF) log is showing the informational message (DB00278I - DATASPACE NAME name) indicating that this MUF is enabling with the named Data Space. How can I confirm if the CA Datacom Data Space is present in the IPCS dump? Also, how can I look at the contents of the Data Space?

Solution:

After you have made the dump available to IPCS, to confirm if the Data Space is present:

Go to the z/OS IPCS PRIMARY OPTION MENU menu.
Select option 4 INVENTORY.
Position the cursor by the dump dataset name in question.
Type either "LZ" or "LD" to the left of DSNAME and press enter.
On the output command line type "F data space name" and hit enter.

If the Data Space is in the dump, the find will position you there with its attributes and address ranges.

Then, how can I look at the contents of a Data Space?

Go to the dump list of address spaces.
Between the data space ASID(X'addr') and AREA, type in the "DSPNAME(data space name) and press enter.
You can then view the data space in the dump, by typing S to select it.
