Private Patch, Maintenance Pack, Service Pack, Rolling Patch


In this topic we are going to discuss about following:

  • Service Pack
  • Rolling Patches
  • Maintenance Pack 
  • Public Patches
  • Private Patches

Service Pack (SP)
A service pack is an update to an existing release that includes solutions to known problems and other product enhancements.
It is not a replacement for an installation of the Oracle product, but a package of changes and enhancements to it.

Prior to WebLogic 9.2 we have Service packs, below are examples for the same:
WebLogic Server 8.1 SP1 to SP6
WebLogic Server 7.0 SP1 to SP7

Rolling Patches 
Between service packs, rolling patches are issued to provide bug fixes for individual components.
A rolling patch does not provide product enhancements.

Note: Service packs and rolling patches are available for download only for registered support customers.

Maintenance Pack (MP)
It is same as Service Pack
Service packs are replaced by maintenance packs starting with WebLogic Platform 9.2 Maintenance Pack 1. 

Maintenance packs are replaced by version upgrades (OraclePatch Set releases) starting with Oracle WebLogic Server 10.3.x.

Oracle Patch Set Releases
WebLogic Server 11gR1 PS5 (10.3.6)
WebLogic Server 11gR1 PS4 (10.3.5)
WebLogic Server 11gR1 PS3 (10.3.4)
WebLogic Server 11gR1 PS2 (10.3.3)
WebLogic Server 11gR1 PS1 (10.3.2)

Patch
Between maintenance packs, patches are issued to provide bug fixes for individual components. A patch does not provide product enhancements.

So  both Patch & Rolling patches are same.


Private Patch
Private Patch is the one which will not be available to all customers. Its atvailable as a private patch under a Service Request. Private patches are no longer available for Smart Update.

Public Patch
A patch that My Oracle Support makes available anyone with a valid support contract.

Note that you can no longer use Smart Update to apply or remove maintenance packs,
version upgrades, or service packs.

Patch set
Set of multiple patches made available for download and installation as a single entity.
