You get SQLCODE -805 when you do have time stamp mismatch in consistency token of the load module and DBRM.
other reasons could be:
- The specified package or program is not defined in the database.
- The program was not bound or it was dropped.
- The application being run is not bound to the database.
- If attempting to run a DB2 utility or CLI application, the DB2 utilities may need to be rebound to the database.
