Together with the DEBUGBMP, IMSnPSBNAME, and IMSnTRANNAME parameters, the IMSnINITBMP parameter helps you to control the activation or deactivation of a BMP region that the IOF can use to process IMS commands. The value of n is a number (1 to 32) of an IMS control region.
This parameter starts or terminates a BMP region. When IMSnINITBMP is set to YES, the IOF sends a subset of IMS commands to the BMP for processing. However, the following commands will still be sent to the IMS WTOR: CANCEL, CHECKPOINT, END, ERESTART, EXCLUSIVE, EXIT, FORMAT, HOLD, IAM, LOCK, MODIFY, MSVERIFY, NRESTART, RCLSDST, and RCOMPT.
When terminating the IMS control region, you must set the IMSnINITBMP parameter to NO to terminate the BMP-dependent region CA OPS/MVS started for this application. The control region cannot terminate until any dependent regions (including the BMP region) have terminated.
You can automate terminating the BMP region by writing a command rule that responds to IMS termination commands by calling the OPSPRM function of OPS/REXX to set the IMSnINITBMP parameter to NO.
NO
YES
Anytime
Example: IMSnINITBMP
This function starts a BMP region that may be used for process IMS commands:
OPSPRM('SET','IMS27INITBMP','YES')
