Identifying members for selective refreshes

In CSVLLAxx, specify the MEMBERS keyword to identify members of LLA-managed libraries for which LLA-cached directory entries are to be refreshed during selective refreshes of LLA. If you issue the MODIFY LLA,UPDATE=xx command to select a CSVLLAxx member that has libraries specified on the MEMBERS keyword, LLA will update its directory for each of the members listed on the MEMBERS keyword.

Selectively refreshing LLA directory allows updated LLA-managed modules to be activated without activating other changed LLA-managed modules. Selective LLA refresh also avoids the purging and restaging of modules that have not changed. When a staged module is refreshed in the LLA directory, LLA purges the copy of the module in the virtual lookaside facility (VLF) data space and may then restage the module into VLF.

For more information about specifying the MEMBERS keyword, see the description of the CSVLLAxx member in z/OS MVS Initialization and Tuning Reference.
