ODAC11 Oracle 9

We have a problem using ODAC11 (client) and开发者_JAVA技巧 Oracle databases version 9.0 and 9.1. It returns error message ORA-604 (something about recursive error on level %). Has anyone else collided with this problem before?

You've got to make sure that the client and server are compatible. The 11 client won't reliably communicate with a server older than 10.2.0.4.
