PATCHING

Patch is a program (set of instructions) to fix a particular problem or enhance/ add a particular feature in existing program/product/software. Patching is one of Jobs Apps DBA do frequently, so we should clear with patch basics and process. Like Database patch, we apply using opatch, similarly for Apps patch we will use adpatch. AD Utility & executables relating to patching reside under product AD and is also called as Application DBA product. There are different types of Patches. The major application patches are as follows:

Standalone/One-off Patch - This patch is created to fix/resolve a particular bug.

Minipack Patch - This patch is the collection of one-off patches.It means it contains group of patches to fix bug in a particular group like GL, AP. The alphabetic characters implies the version of minipack version for the module.For an example 11i.GL.E means E version of GL product is released.Minipack patch is cumulative that means 11i.GL.E includes 11i.GL.A, 11i.GL.B…….11i.GL.D,11i.GL.E.

Family Pack Patch - This patch is the collection of minipack patches for a particular family group of application modules.These are usually named as 11i_PF. For an example 11i.SCM_PF.G, here PF indicates product family pack.

Maintenance Pack – This patch is the collections of family packs that serves as point level release upgrade. Oracle Application R11,R12 are examples of a Maintenance pack.
