5.5 PatchiX Training

The expectation is that phase I can be performed with users on the system during normal
business hours, while phase II is performed at night or on the weekend during the systems
scheduled downtime period. This two phased approach has several key benefits:
• By doing setup, patch qualification, library modification, and tape creation while
the system is available to users, downtime required to apply a set of patches is
reduced.
• By allowing reactive patches and PowerPatch patches to be managed and applied
simultaneously, downtime is reduced significantly over the old double update
approach.
• If a problem occurs during any point through tape creation the system and users
are not affected. The system manager has time to determine the problem, without
worrying about the system being down.
• The actual installation from the patch tape is a simple process that in many
businesses could be handled at night by an operator.
