RTCS product registry

The RTCS product registry is a repository for product-specific information. It is defined by the products and is optionally backed by a VSAM LDS cluster.

Warning

Note

This VSAM LDS cluster must be allocated for use by the RTCS subsystem to back the primary RTCS registry partition using the z/OS Data-In-Virtual (DIV) service. Because it is a VSAM cluster and will be dynamically allocated by the RTCS subsystem address space using only its DSNAME, this library must be cataloged.

All processing activity uses the same access techniques as the RTCS system registry, and like the RTCS system registry is organized in a tree-like structure.

The RTCS product registry can optionally be shared with another copy of the product address space either on the same system or on a different z/OS image in the same sysplex. In the shared mode, one of the product address spaces becomes the local registry owner and manages all access to the RTCS product registry. The other product address spaces become remote registry accessors and make requests to put data into the registry and to retrieve data from the registry to the local owner through an XCF communications pipeline.
