TSMAINLIMIT
The TSMAINLIMIT system initialization parameter specifies a limit for the storage that is available for main temporary storage queues to use. You can specify an amount of storage in the range 1 - 32768 MB (32 GB), but this amount must not be greater than 25% of the value of the z/OS parameter MEMLIMIT. The default is 64 MB.
- TSMAINLIMIT={64M|nnnnnM|nnG}
- 64M
- The default setting in megabytes.
- nnnnnM
- An amount of storage in megabytes. The allowed range is 1 - 32768 MB.
- nnG
- An amount of storage in gigabytes. The allowed range is 1 - 32 GB.
For example, TSMAINLIMIT=2G makes 2 GB of storage available to main temporary storage queues.
When you set this parameter, check your current setting for the z/OS parameter MEMLIMIT. MEMLIMIT limits the amount of 64-bit storage that the CICS address space can use. Your setting for TSMAINLIMIT must not be greater than 25% of the MEMLIMIT value.
