SQA
Type
OMEGAMON Minor command
Description
Displays SQA by subpool and protect key. (There are other entries with the same name. See the previous entry for a description of SQA as a minor of address space majors.) SQA displays the number of bytes used as well as allocated for those subpools that are not in fetch-protected memory. Protected subpools display *AUTH* in the Used column. This is because the control block OMEGAMON needs to get the information, the FQE, is in the subpool.
The SQA utilization display shows the extents, allocated blocks, storage used, and the largest free block.
