Service items are activated from service activation libraries that have been identified via the SERV_LPALIB and SERV_LINKLIB parameters in the BPXPRMxx member. The service activation libraries contain the service items that have already been SMP/E-installed and that you want to activate on the next F OMVS,ACTIVATE=SERVICE command. The libraries enable you to identify for a given activation request the normal LPALIB and LINKLIB target libraries where you install service via SMP/E for future IPLs or a specific library where you have installed a specific fix. For example:

SERV_LINKLIB('dsname','volser')

The SERV_LINKLIB statement identifies the target service library where the z/OS UNIX modules that are normally loaded from SYS1.LINKLIB into the private area of the OMVS address space are located.

• The dsname parameter identifies a 1-to-44 character value that represents a valid data set name for the specified MVS™ load library. This library must be APF-authorized. The alphabetic characters in the load library name must be uppercase.
• The volser parameter identifies a 1-to-6 character value that represents a valid volume serial number for the volume that contains the specified MVS load library. The alphabetic characters in the volume serial number must be uppercase.
