Do you use the IBM Support Portal ?

One more blog entry for the weekend.
You may use the IBM Support Portal to verify, if a problem is already know and an APAR is available. The link to the portal is here.
You may start with the selection of the product, that you want to search for.
Just select e.g. IBM Operating Systems -> z/VSE, then enter the symptoms of your problem in the search field. That is you could search for a specific abend, or message number, or component id and so on. E.g. if you have an abend in CICS related to VSAM access, you could search for "vsam abend cics". You would get APARs and/or Technotes related to that query.
Have a good weekend.
