Caching RACF user and group information in VLF z/OS UNIX System Services Planning GA32-0884-00 |
|
Caching UIDs and GIDs improves performance for commands such as ls -l, which must convert UID numbers to user IDs and GID numbers to RACF® group names. RACF allows you to cache UID and GID information in virtual lookaside facility (VLF). Guideline: To avoid performance degradation, VLF should be made active. For more information about performance considerations, see RACF performance considerations. |
