Setting: ASP.Net application with Oracle backend, we utilize User Defined Types (UDTs) and use ODP.Net to communicate them between the front and back-ends.
Problem: I had to alter one of my UDTs attribute length, once I did that and tested in backend it worked fine, but when I run my site I keep getting the ORA-22337 error (in subject line)!!
You will not find much if you research this problem online, other than the useless Oracle error documentation you will not find anything helpful. The Oracle documentation says to close and re-open the connection, but that does not apply to my scenario
I already solved the problem by dropping and recreating the UDTs and NTs, but this is inefficient to have to do every time I need to modify one of my core UDTs, any ideas how to solve this without dropping and recreating everything?
If the error info says "Close and reopen the connection" as the solution and you are using a OracleConnection which has a connection pool in it, then simply Close()ing the connection is not good enough. It will just go back to the pool still open and when you "reconnnect" you will just get it back again. You'll need to Close all open connections and then call ClearPool() to make sure that all old connections in the pool are removed.
