Local system queue area (LSQA/Extended LSQA)

Each virtual address space has an LSQA. The area contains tables and queues associated with the user's address space.

LSQA is intermixed with SWA and subpools 229, 230, and 249 downward from the bottom of the CSA into the unallocated portion of the private area, as needed. Extended LSQA is intermixed with SWA and subpools 229, 230, and 249 downward from 2 gigabytes into the unallocated portion of the extended private area, as needed. (See Figure 1.) LSQA will not be taken from space below the top of the highest storage currently allocated to the private area user region. Any job will abnormally terminate unless there is enough space for allocating LSQA.
