Dynamically activating maintenance for z/OS UNIX System Services (z/OS UNIX)

Use the MODIFY OMVS command to dynamically activate maintenance for z/OS UNIX System Services.

F OMVS {,ACTIVATE=SERVICE}
       {,DEACTIVATE=SERVICE}
 

The parameters are:

ACTIVATE=SERVICE

Requests that the system dynamically activate SMP/E installable service for the z/OS UNIX kernel and logical file system (LFS) components without requiring a component restart or system IPL. The system activate the service from the target libraries specified in BPXPRMxx parmlib statements, SERV_LPALIB and SERV_LINKLIB. When the F OMVS,ACTIVATE=SERVICE is issued, the system allocates and opens load libraries specified on SERV_LPALIB and SERV_LINKLIB to locate and load the new services items. Therefore, do not update these libraries during the activation process.

Restriction: The ACTIVATE=SERVICE parameter will only activate those service items in the target libraries that are appropriate for the installation service level. Your installation's service level might be too low to allow dynamic activation of some service items in the target library.

Result: The system issues message BPXM061I to display the service items to be activated. It then issues BPXM061D and prompts for the activation to continue based on the information in BPXM061I. The operator can reply 'Y' to let activation continue. Any other reply cancels the command.

You can also use the DISPLAY command (D OMVS,ACTIVATE=SERVICE) to display the dynamically activated service. See Displaying z/OS UNIX System Services Status.

DEACTIVATE=SERVICE

Requests that the system dynamically back off a set of dynamically activated service items. You might need to use this command if you encounter a problem with a service item, or if you do not need it any longer. The DEACTIVATE=SERVICE parameter dynamically deactivates only those service items that were activated with the previous ACTIVATE=SERVICE command.

Result:The system issues message BPXM063I to display the service items to be deactivated. It then issues message BPXM063D and prompts for the deactivation to continue based on the information in message BPXM063I. The operator can reply 'Y' to let deactivation continue. Any other reply cancels the command.

You can also use the DISPLAY command (D OMVS, ACTIVATE=SERVICE) to display the dynamically activated service. See Displaying z/OS UNIX System Services Status.
