Understanding PeopleTools Patch
PeopleTools patches deliver fixes between PeopleTools minor releases. PeopleTools patches are posted to My Oracle Support, as they become available. PeopleTools patches are cumulative. They include all fixes from all previous patches for the specified release. For example, patch .03 contains all the fixes contained in the .02 patch as well as all of those contained in the .01 patch.
The patch is provided in the PeopleTools DPKs. For information on using the PeopleTools DPKs, see PeopleSoft PeopleTools Deployment Packages Installation.
The PeopleTools patch location is always the PTP directory in your target PS home.
