IMS support
BCF supports IMS as follows:
IMS requirements
Your installation must have a licensed copy of the IMS Database Manager.
BCF is supported for use with all IBM-supported versions of IMS. For complete information about BCF support for operating systems, hardware, and database management systems, you can use the Product Availability and Compatibility (PAC) utility on the BMC Support Central website at http://www.bmc.com/support.
BCF supports all PSB PROCOPTs and DL/I databases.
DBRC
BCF fully supports DBRC. It does not replace or enhance any existing function of DBRC. The BCF Physical Logger provides the same level of DBRC support as the current IMS logging function provides.
Region types
BCF can participate in the execution of IMS batch programs that use these types of IMS regions:
- DLI (DB batch)
- DBB (DB batch)
- ULU
In a utility (ULU) environment that requires logging, the BCF Physical Logger can service the logging requests. When BCF is processing in a ULU environment, the execution controller initializes but does not perform automatic batch backout or exchange log device types. DUMMY logging is not supported for ULU regions.
BCF does not participate in BMP or MPP executions.
BCF participation in manual batch backout
When the IMS Batch Backout utility is executing in a DLI environment, the execution controller initializes but does not perform automatic batch backout or exchange log device types.
However, the Batch Backout Assist function remains active. If the IMS Batch Backout utility abends, the execution controller issues message BMC44242I with reason code 18 to indicate that manual intervention is required. It then deletes the execution control record. and the log volume record(s) from the REGISET.
Uncataloged data sets in STEPLIB
Uncataloged or temporary data sets that are included in the STEPLIB concatenation are not supported.
AR/CTL products are excluded from execution when the STEPLIB contains an uncataloged or temporary data set.
