MESSAGEPOOLSIZE
The MESSAGEPOOLSIZE parameter specifies the size of the memory region in bytes for most memory allocation.
Description
Specify a region size that is at least 8 MB lower than the site limit, and use the greater of these values:
- 8 MB higher than the message pool
- 20% higher than the message pool
If the 8 MB gap between the region and the message pool is still not sufficient, increase this difference in increments of 8 MB.
Set the MESSAGEPOOLSIZE parameter to the greater of these values:
- 20% less than the region size
- 8 MB below the REGION value or 8 MB below any site limit imposed by exits.
If you increase the value of the MESSAGEPOOLSIZE parameter, set the region size higher to maintain the 8 MB gap.
