Overview
Steps for Running a No-Roll Procedure
Throwing the Version Switch
Removing Patches

The no-roll patch process lets you install patches on a cluster without performing a rolling upgrade. This chapter provides the following information:

An overview of the no-roll patch process (“Overview”)
A step-by-step description of the process as it differs from a normal dupatch session (“Steps for Running a No-Roll Procedure”)
Throwing the version switch (“Throwing the Version Switch”)
How to remove patches from a cluster using the no-roll patch method (“Removing Patches”)




	Note: The no-roll technology is included in Rev. 34–00 and higher of the dupatch utility. You can find the revision number on the first output line you see when you run dupatch (see the example in “Steps for Running a No-Roll Procedure”). The first kit that includes this technology was issued in April 2002.
