Occasionally we have IBM TRIRIGA customers who need clarification on the differences between Fixpacks and Limited Availability fixes. I want to share this information with you and state best practice guidelines here:
GENERAL AVAILABILITY FIXPACK (GA FIX)
GA Fixpacks deliver product defect fixes that have undergone a full development release cycle and the most extensive QA testing of all maintenance releases.
These fixes are delivered for any issue reported either internally or externally regardless of severity. Fixpacks occasionally deliver minor functional enhancements and modifications to add or update supported platforms, browsers, databases, middleware, etc.
Fixpacks are cumulative and each new fixpack contains all fixes from all previous fixpacks/interim fixes for that release.
LIMITED AVAILABILITY FIX (LA FIX)
An LA Fix is an unofficial mechanism to deliver emergency fixes for severe product issues that cannot be delayed until the next regular maintenance delivery. LA Fixes also go by the names “1-off” or “1-off Hotfix” but they all mean a single APAR fix delivered directly to a customer from Support.

BEST PRACTICES FOR FIXES
It is perfectly acceptable to take an LA FIX to address an issue when warranted. However, the risk associated with taking an LA FIX should always be weighed against the perceived benefits. If at all possible, it is always best to wait for a fully tested GA Fix. Also, if you do take an LA Fix, it should only remain in place until a GA Fix containing the fix needed is available. At that point, the GA Fix should be applied.
