Overview of DB2 Component Services (DBC)

The DB2 Component Services (DBC) technology provides a persistent z/OS subsystem address space into which enabled BMC products can dynamically initialize their own product services.

DBC uses a variety of techniques to accommodate dynamic initializations:

  • Through an XML messaging protocol, DBC provides a non-authorized, loosely coupled, sysplex-enabled communication channel to product services.
  • DBC hosts common services for IBM DB2, IMS, and MQ subsystem discovery and command execution.
  • DBC allows BMC products to define operator commands, and to subscribe to and publish user events dynamically.

All product services that are hosted within the DBC infrastructure inherit a Security Access Facility (SAF) interface to ensure compliance with the relevant site's security requirements.

The FMID that corresponds to DBC technology is ZDBCxxx, where xxx represents release number information.

Note

For information about maintaining and using the DBC, see Working-with-DB2-Component-Services-DBC. For information about using the DBC with a particular product, see that product's documentation.
