During the early stages of an install or upgrade, a user may see a rc=-3 and an 806-04 abend: CSV003I REQUESTED MODULE DSNTZANB NOT FOUND CSV028I ABEND806-04 JOBNAME=TECA796 STEPNAME=SPFTECH System abend code 806, reason code 00000004.

Symptom
An 806-04 abend and/or RC=-3 will appear on the user's console, and the user will then see a panel indicating that a SQL error occurred while executing DSNREXX.
Cause
The Optim installation process uses DSNREXX to obtain the current DB2 release. The error occurs either because the DSNREXX plan is not bound, or because the DSNREXX module is not available by the TSO logon procedure (STEPLIB or ISPLLIB), the system link list, or the link pack area. A DB2 limitation prevents DSNREXX being called via DB2 libraries that are LIBDEF'ed.
Diagnosing The Problem
Check to see if the DSNREXX plan is bound and accessible to the Optim user. If it is, check to see if the DB2 library containing DSNREXX is available via the TSO logon procedure or is globally available.
Resolving The Problem
Bind the DSNREXX plan if required, and make sure that the library containing the DSNREXX load module is available by the TSO logon procedure, system link list, or link pack area. Alternatively, follow the directions on the panel to hit 'END' and allow Optim to continue the installation and determine the release of DB2 from DSNHDECP.
