IMS requirements
To use Subzero as an interface between IBM CICS and IBM IMS, you must have a license for the BMC Subsystem Optimizer for IMS product. To use Subzero as an interface between IBM IMS and IBM DB2, you must have a license for the BMC Subsystem Optimizer for DB2 product.
Subzero supports IMS Version 12.1 and later. For the latest information about the compatibility of Subzero with a specific release of IMS, use the BMC Solution and Product Availability and Compatibility Utility on the BMC Support Central website (http://www.bmc.com/support).
Subzero supports all Data Language I (DL/I) application program calls to IMS databases. Subzero supports all DL/I calls that are normally available within the application execution environment (such as CICS).
When a client (such as a CICS region) makes a connection to an IMS system, a Subzero subsystem server address space starts on the remote LPAR to work with that connection. This Subzero address space requires that the DFSPZPxx module, which contains startup parameters for the IMS Database Resource Adapter (DRA), can be loaded into memory. The system attempts to load the required DFSPZPxx member from the following sources:
- IMS RESLIB specification within the DFSPZPxx member itself
- STEPLIB or JOBLIB concatenation in the Subzero startup procedure (BRDPROC)
- System linklist or link pack area (LPA)
You can ensure that DFSPZPxx can be loaded by modifying the STEPLIB in BRDPROC to include the library that contains DFSPZPxx. If the client contains an IMS RESLIB specification that provides only the DFSPZPxx ddname (the IMS RESLIB data set name is null), specify that same ddname in BRDPROC.
