Dynamically changing the BPXPRMxx parameter values

The SETOMVS command enables you to modify BPXPRMxx settings without reIPLing.

You can dynamically change process-wide limits separately for each process. For example:

SETOMVS PID=123,MAXFILEPROC=200

The SET OMVS command enables you to dynamically change the BPXPRMxx parameters that are in effect. Because you can have multiple BPXPRMxx definitions, you can easily reconfigure a large set of the system characteristics. You can keep the reconfiguration settings in a permanent location for later reference or reuse. A sample SET OMVS command is:

SET OMVS=(AA,BB)

If a parameter is specified more than once with different values, in the parmlib members, the first value that is specified is the first value that is used. For example, if you specify SET OMVS=(AA,BB) where AA has a MAXPROCUSER=10 value and BB has a MAXPROCUSER=5 value, MAXPROCUSER =10 is used.

You can use the SETOMVS RESET command to dynamically add the FILESYSTYPE, NETWORK, and SUBFILESYSTYPE statements without having to reIPL. However, if you change the values, a reIPL will be necessary. For more information, see Dynamically adding FILESYSTYPE statements in BPXPRMxx.

SET OMVS=xx can be used to execute the ROOT, MOUNT, FILESYSTYPE, SUBFILESYSTYPE, and NETWORK statements in the BPXPRMxx member.
