This value becomes the setting of the MLMT parameter for the IRLM address space procedure. The IRLM address space procedure sets the z/OS® MEMLIMIT value for the address space.

Ensure that you set this value high enough so that IRLM does not reach the limit. The value that you choose should provide space for possible retained locks. IRLM only gets storage as it needs it, so choose a large value. You can also change the value dynamically by using the z/OS command MODIFY irlmproc,SET,MLT.

The associated IRLM PROC parameter is MLMT.
