Patching Basic info
One
of the main tasks is as a oracle application dbas to applying the patches.
Patches are required to resolve problems with the
application code, to fix production issues, to install new features, or to
upgrade components of the technology stack.
Applying a patch involves several steps, such
as unbundling the patch, enabling maintenance mode, applying the patch with
adpatch, and implementing manual steps. This section will discuss each of the
steps involved
Application Patch: AutoPatch (adpatch) is a utility
that is used to fix a bug or new enhancement.
Types of Application Patches
There are several different types of Oracle
Applications patches. These are the more common patches
ΓΌ One-off patch: This is the simplest type of patch. It is created to
resolve a specific bug.
Minipack patch: This is a collection of one-off patches and enhancements
related to a particular module. Alphabetic characters denote the Minipack
version for the module; for example, the product code for the Application DBA
utilities is AD, and version Minipack I of this product would be called AD.I.
Family Pack patch: This is a collection of Minipack patches for a particular
family group of application modules. Alphabetic characters denote the Family
Pack version; for example, the J version of the Human Resources Suite Product
Family would be HR_PF.J.
Maintenance Pack patch: This is a collection of Family Packs that serves as a
point-level release upgrade
Consolidated patch: This is a collection of one-off fixes for a Family Pack
or Maintenance Pack.
Interoperability patch: This is a patch that is required for Oracle Applications
to function with a newer version of a technology stack component; for example,
you would apply an interoperability patch when upgrading the database to
version 10g.
NLS patch: This is a patch that updates language-specific
information for multi-language installations.
Rollup patch: This is a collection of one-off patches that update
code levels for particular products
Legislative patch: This is a special patch for HR Payroll customers; it
