Occasionally, we have IBM TRIRIGA customers who need clarification on the differences between General Availability fix packs and Limited Availability fixes. I want to share this information with you and state the best-practice guidelines here.
General Availability (GA) Fix Pack
A GA fix pack delivers product defect fixes that have undergone a full development release cycle and the most extensive QA testing of all maintenance releases…
Limited Availability (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. An LA fix also goes by the name “one-off” or “one-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 pack. Also, if you do take an LA fix, it should only remain in place until a GA fix pack containing the needed fix is available. At that point, the GA fix pack should be applied.
