17. HP-UX Patch Program 17 patching strategy philosophy quarterly proactive patching HP-UX 10.20 exception based on release of SupportPlus media goal: no unscheduled downtime switch from reactive to proactive maintenance to improve supportability 3 month test cycle in lab before rolling to production Brigham Young University patch strategy

18. HP-UX Patch Program 18 patching strategy patch warnings QPK bundles reduce probability of a patch warning security patches may be applied reactively Brigham Young University patch strategy

19. HP-UX Patch Program 19 patching strategy patch application clusters of redundant applications maximizes system availability non-redundant applications require off hour planned outages problems generally logged with the ITRC call manager Brigham Young University patch strategy

20. HP-UX Patch Program 20 change management formal change request process all system changes are logged Brigham Young University change management

21. HP-UX Patch Program 21 conclusions- recommendations quarterly proactive patching as virtually eliminated unscheduled downtime and reactive patching quality of patches in QPK helps to stabilize systems – reduces risk adequately test before rolling to production eliminating the need for system administers from working nights would be a plus! Brigham Young University conclusions
