VLF keeps objects (for example Load modules) in Virtual Storage in order to save I/O operations that would load such objects. Designed primarily to improve performance by retrieving the most currently used objects from Virtual Storage rather then performing repetitive I/O operations from DASD. VLF can be configured by using […]
It’s a program management z/OS component that keeps in Virtual Storage Directory entries from Load module libraries, thereby speeding up the fetch of a Load module. LLA improves the performance of Load Module Directory searching on the system. LLA can be a user of VLF facilities to keep copies of […]
