Stopping a System Object Model (SOM)

Use the STOP SOM command to stop the distributed SOM subsystem. This is the extension to the SOMobjects® product that allows programs to communicate with objects in other processes that reside in other address spaces or other systems. Executing this command causes the SOM subsystem to wait for all servers to end, and then to stop. See SOMobjects Configuration and Administration Guide, GC28-1851, for more information on stopping the SOM subsystem.

 
P SOM

The parameter is:

SOM: The name for the SOM subsystem. It corresponds to the cataloged procedure in SYS1.PROCLIB that starts SOM. A sample cataloged procedure is located in MVSDSOM.DR03.SGOSJCL(PROCDSVR).

Note: In order for this command to be effective, the SOM daemon address space must be active.

Example:

To stop the SOM daemon address space, enter:

P SOM

When you enter the STOP SOM command, the system displays these messages:

GOS041I SOM/MVS SOMI WAITING FOR SERVERS TO END.
GOS010I SOM/MVS SOMI ENDED.

The system might also display the following message:

IEF352I ADDRESS SPACE UNAVAILABLE

This is normal and you should not report it as a problem. The consequence of purging SOM is that it makes the address space identifier (ASID) permanently unusable, for system integrity reasons.
