ORA-28112: failed to execute policy function tips

Oracle Database Tips by Donald BurlesonApril 30, 2015


Linda asks:  Is there any way to determine why I'm getting the error ORA-28112: failed to execute policy function?  I take the predicate and add "where" and the predicate text to the select statement on the view that my policy function is working against, it works perfectly. Do I have any other options besides a trace file to track down the root cause of the "ORA-28112: failed to execute policy function" error?

Answer:  ORA-28112: failed to execute policy function occurs when the policy function encounters some runtime errors, typically unhandled exceptions. Fortunately, the error will produce a trace file in the user_dump_dest directory that can be examined and the error can be corrected.  You need to see the trace file for additional details on the ORA-2812 error.  The docs note:

ORA-28112: failed to execute policy function

Cause: The policy function has one or more error during execution.

Action: Check the trace file and correct the errors.

You can check your trace file for these details. I have a working example of a VPD policy invocation here.  In my experience, the ORA-28112 error is almost always an unhandled exception, and you can display the exact exception using the PL/SQL "WHEN OTHERS" clause.
