CMSC overview

The CMSC address space is a centralized facility providing license management and common parameter library services. The CMSC can also automatically start HCI address spaces. HCI address spaces started by the CMSC will automatically restart in the event of a failure.

As the service provider for the new Common Parameter Library feature (PARMLIB), the CMSC reads the user’s parameter libraries, stores parameters for BMC AMI products in memory, and initializes the parameter retrieval service used by BMC AMI products. Operator commands are provided to refresh the parameters in memory in the event of a change to one or more of the parameter library members.

ECC enables BMC mainframe products to use PARMLIBs for storing configuration data. Instructions are provided to guide you through any necessary migration to using PARMLIBs.

Multiple BMC mainframe products, with a release of 17.02 or greater, use a common PARMLIB for specifying configuration and customization parameter values, serviced through the CMSC address space. Parameter values are stored in a PDS or concatenation of PDS libraries. The PARMLIB members are human readable and editable, allowing administrators to view or change values using an operator command. z/OS System Symbolics are supported by PARMLIB members, which can be helpful in simplifying, for example, multiple LPAR deployments.

PARMLIB to all BMC mainframe products release 17.02 and higher, similar product information can be expressed to more than one BMC AMI product. For example, BMC AMI Strobe information can be defined for both BMC AMI Strobe and another product, like HCI.

Users can also specify different PARMLIB members for different invocations of individual products. For example: HCInn, where nn identifies the PARMLIB member to be used.
