IMS Operation Facility › Issue Commands from a BMP Region

Issue Commands from a BMP Region

If a batch message processing (BMP) region is available, the IOF can use it to issue IMS commands and retrieve command responses. This ability is an alternative to CA OPS/MVS using the IMS WTOR method whenever it needs to issue an IMS command.

The IOF use of a BMP region for IMS commands has these advantages:

• The IOF can issue most IMS commands without waiting for the IMS WTOR.
• Command responses are more reliable and more efficient because command output is neither automatically routed to the consoles (as it would be if the commands were issued through the IMS WTOR) nor routed through the subsystem interface (SSI).

Perform these steps to take advantage of the CA OPS/MVS ability to use a BMP to issue IMS commands:

1. Set the IMS parameter AOIS= to a value other than N, which is the default value.

   Note: For a list of possible values, see the IMS installation manuals.

2. Authorize the BMP TRAN to Issue All Commands

   You must run the IMS Security Maintenance Utility (SMU) to specify that the BMP TRAN has authority to issue all commands.

3. Create a Batch BMP Started Task JCL

   Use the IMS PROCLIB member IMSBATCH, and make sure the RESLIB that it is using matches the RESLIB of the control region that you want to target. Add the CA OPS/MVS load module library to the STEPLIB concatenation.

   Set the CA OPS/MVS IMSnBMPSTC parameter to the member name of the BMP started task JCL.

4. Specify CA OPS/MVS Parameters

   To control the activation or deactivation of the BMP region that the IOF uses to issue commands, you need to set these CA OPS/MVS parameters:

   • IMSnBMPSTC
   • IMSnINITBMP
   • IMSnPSBNAME
   • IMSnTRANNAME
   • DEBUGBMP

   For more information about these parameters, see the Parameter Reference.

Note: You do not need to change any of your existing automation to take advantage of the ability of CA OPS/MVS to use a BMP in this way. As long as you have performed the steps above, you can continue issuing your IMS commands as you always have (for example, through the OPSCMD command processor or the ADDRESS OPER host environment) and CA OPS/MVS will use the BMP mechanism if it is available.
