Buffer manager data records

The format of the buffer manager statistics record is described in assembler macro thlqual.SCSQMACS(CSQDQPST).

Note:
If you have defined a buffer pool, but not used it, no values are set so the buffer manager statistics record does not contain any data.

When interpreting the statistics, you are recommended to consider the following factors because the values of these fields can be used to improve the performance of your system:

  1. If QPSTSOS, QPSTSTLA, or QPSTDMC is greater than zero, you should either increase the size of the buffer pool or reallocate the page sets to different buffer pools.
  2. For buffer pool zero and buffer pools that contain short-lived messages:
  3. For buffer pools with long-lived messages, where there are more messages than can fit into the buffer pool:
