[OAUGNetDBA]-Re: Question on merging patches

["James Morrow" <morrow.james@gmail.com>]

NOTE:  This has been true since AT LEAST the first release of AD.H.

Note:  174436.1 "Oracle Applications Patching FAQ"
Note:  457566.1 "Oracle Applications Patching FAQ for Release 11i"
Note:  459156.1 "Oracle Applications Patching FAQ for Release 12"
(For you R12-ish types)


>From 457566.1:

Can I apply multiple patches in one operation?

  Before you run AutoPatch, use AD Merge Patch to merge multiple patches
  into a single, integrated patch so that the required patching tasks
  and processes are performed only once. In general, you can safely merge
  any Oracle Applications patch with another Oracle Applications patch.
  Patches should be merged with their listed prerequisite patches to make
  the application of the patch easier. However, patches that affect the
  Applications DBA (AD) product may change the AutoPatch utility itself.
  So, they can be merged only with other AD patches and must be applied
  separately, before you apply any non-AD patches.

  Note: AD Merge Patch cannot merge patches of different releases,
  different parallel modes, or different platforms. However, it can
  merge patches for a specific platform with a generic patch, or
  patches with different source character sets. The utility notifies
  you if you try to merge incompatible patches.

Do patches need to be applied in a particular order? What is a
prerequisite patch?

  AD patches are the only patches that must be applied in a specific order.
  This is necessary because you may need to patch the patching utility
  itself so that it works properly when you use it to apply subsequent patches.
  It is not necessary to apply non-AD patches in a particular order,
even though
  a readme may state a specific order is required.

  A prerequisite patch fulfills a dependency for another patch.
Strictly speaking,
  they are co-requisites and can be applied in any order before using
the system.
  We recommend that you merge a patch with its required prerequisites, with the
  exception of prerequisite patches for the AD product.

  Starting with AD Minipack H, AutoPatch has a Prereq feature that,
when run with
  patches containing metadata, automatically determines if
prerequisites are not
  fulfilled and informs you. At this point, you can download the prerequisites,
  merge them with the patch, restart AutoPatch, and apply the merged patch.

  Older patches, or patches whose metadata is missing the prerequisite
information,
  may list prerequisite patches in the patch README.

  See Oracle Applications Maintenance Utilities for information.
