Displaying the kernel address space

To find the kernel address space and associated data spaces, issue:

D A,OMVS

The output will be similar to the following:

The display output shows the kernel address space identifier (ASID) as A=nnnn where nnnn is the hexadecimal ASID value. In this example, A=000E. The display output also shows the data space names that are associated with the kernel address space.

When the list of address spaces being dumped includes a dubbed address space or the kernel (OMVS) address space, the CTRACE buffers are automatically included in the dump and need not be explicitly added to a DUMP command or SLIP trap.

Dump other data spaces if there is reason to believe that they contain data that could be useful in analyzing the problem.
