This is quite tricky one to know. Well i thought so.
-904 SQLCODE: Unavailable resource.
-911 SQLCODE: Deadlock or timeout.But i am talking about timeout here.So we will get timeout since the resource is not available so the application will go in suspention mode and wait for some time( equal to IRLMRWT DSNZPARM paramater)and then timeout.
SO WHAT EXACTLY THE DIFFRANCE BETWEEN -911 WITH TIMEOUT AND -904.
A -911 is a lock timeout and occurs only when trying to access data that is locked by another process.
A -904 is a resource unavailable, and can be caused by any number of resources that are not available. The -904 will have an associated reason code and type code. The reason tells you the "why" and the type code will tell you the "what." Reason codes and type codes are documented in the DB2 for z/OS Codes manual which is GC19-2971 for Version 10.
