To achieve the most benefit from LPA usage, copy CA OPS/MVS module OPSAEX into an LPALST library. By doing this, you are enabling OPSVIEW and all of the CA OPS/MVS command processors to execute more quickly and to share common code. This can reduce the overall demand for real storage and paging.
If you decide to place the OPSAEX load module in the LPA, you can allow the main address space to share many of the modules that OPSAEX contains. If you choose to do so, add the following DD card to the OPSMAIN JCL:
//OPSAEX DD DUMMY
Doing this reduces the amount of ECSA used by the main product address space by approximately 400 KB when OPSAEX resides in the LPA. If you omit this ddname, then the main address space makes no attempt to share OPSAEX, even if it resides in the LPA.
