Often, we receive Problem Records (PMRs) or Service Requests (SRs) requesting a fix for a specific APAR problem. If the fix is included with a published fixpack, we generally recommend that the user apply the latest fixpack rather than requesting an interim fix.
Interim fixes are often not available on fix central for general download. We encourage users to apply the fixpack if possible. Interim fixes do not undergo the same rigorous 3 month cycle of thorough testing involved in certifying a FixPack. If a user wants an interim fix for a specific APAR, then we need to check the platform, MQ versions and other possible ifixes applied for compatibility. This requires that a new ifix may need to be prepared and bundled for each environment, so it is often more time effective for a user to download and apply the fixpack that includes the APAR fix they need.
Additionally, applying the current fixpack assures that you have fixes in place for numerous other known problem. To see a full list of APARs included in fixpacks, please refer to these support documents:
