Patch Management User Guide for HP-UX 11.x Systems (5900-3011, March 2013)

Considerations
• You should have a detailed recovery plan formulated before you install any patches.
• You should know how long the system can be down for patch installation, and set aside a
portion of that time for recovery in case it is required.
• When patching critical systems, some customers have a redundant environment in place to
take over in the event that anything goes wrong with the production system.
• If you install patches with patch rollback files, then patch rollback will be an option if there
are problems with the patch installation. See “Patch rollback and commitment” (page 34).
