LPA Library Display

The link pack area (LPA) is a special area of virtual system storage that is reserved during the system IPL. The LPA contains routines and programs that all tasks on the system can access concurrently. The LPA area is loaded with fresh copies of routines and programs whenever the create link pack area (CLPA) option is specified during an IPL. Multiple LPA libraries can be present as defined in the LPALSTxx member of the logical parmlib.

The LPA libraries contain the SVC routines, access methods, and selected user programs that all tasks on the system can use concurrently. Because the LPA libraries contain these vital components of the system, you must ensure that they are protected properly.
