Although CA CSM can run on any LPAR configuration, we recommend an LPAR that has at least two CPUs configured.
Note: CA CSM takes advantage of the zAAP processor, which may help increase general purpose processor productivity and contribute to lowering the overall cost of computing for z/OS Java technology-based applications.
Business Value:
CA CSM is an online application that runs three address spaces (MSMMUF, MSMDBSRV, MSMTC). Configuring multiple CPUs allows multiple instructions to be processed, ensuring less CPU wait delays, and improving overall response times for CA CSM users.
In a uniprocessor LPAR configuration, CA CSM users may experience significantly slower response time, which reduces some of the productivity gain that the tool provides.
When SAF security is enabled, CA CSM spawns a fourth Open MVS Transaction (OTX) address space for the security interface, which is CA Distributed Security Integration for z/OS (CA DSI) to the external security manager on the host system.
