Operating the BCSS/CPC subsystem
The BCSS/CPC subsystem manages APF-authorized functions and performs processing for intercepted MVS requests.
Only one public BCSS is allowed on an MVS; however, you can have multiple private BCSSs. BMCP allows the public BCSS first access to an intercepted request and ensures that the appropriate BCSS receives control when required.
BMC System Administration for IMS uses the BCSS subsystem in conjunction with CPC technology. If CPC is installed with the BCSS subsystem, the solution can share a BCSS subsystem with other BMC products.
Always use the latest version of the BCSS subsystem. Use the BCSCHECK program to determine whether an earlier version of BCSS is installed on your system. For details about the BCSCHECK program, see the BMC Software Subsystem User Guide.
BMC recommends that the BCSS/CPC subsystem always remain active. However, you must terminate a subsystem to install maintenance modules for that subsystem.
For detailed information about the BCSS subsystem, see the BMC Software Subsystem User Guide.
