Single Fixes At A Glance.
By ACShorten on Oct 07, 2009
One of the features of the Oracle Utilities Application Framework based products is the ability to implement single fixes. A single fix, as the name applies, is a software based fix for a particular bug or problem register by a customer, partner or even internally.
The idea is that if a specific problem is found then we can ship a specific fix for that problem. Sounds simple enough. Well, it all sounds simple but it can get more complex due its power. With great power, comes complexity.
The Single Fixes infrastructure is used for far more than just fixes. It is reused for a number of key deliverables:
- Off New functionality is introduced off cycle using single fixes - Obviously, the new funtionality is not "enabled" by default for backward compatibility.
- Service Packs are delivered as single fixes - This represents a group of single fixes in one install package.
- Language Packs are delivered as single fixes - Products are multi-lingual so packs for individual langauges are available as single fixes.
- Fixes not related to the current release are delivered as single fixes - If a problem is registered in a past verison of a product and has been identifed as a potential problem in the current release, then a single fix for the "retrofit" may be released. You will usually see the words "Copy of..." in the single fix title and the number of the past fix number.
This can lead to a lot of fixes listed on the support site.
To minimize the impact of installing single fixes, I recommend the following:
- Only install the single fixes that apply to your site. Most cases you just want to install the single fixes that YOU register.
- Wait for Service Packs. The Service Packs are a cumulative collection of all the fixes available in one download and install. This is the easiest way to keep up.
There is a My Oracle Support KB ID (804612.1) on the important fixes. If you look at the list it is a list of individual single fixes to install. To install them all, the easiest way is to install the latest service pack.
