Hi, since we updated our ASA 5550 to 18.104.22.168 we're having problems with our SQLNET (port 1521 with Oracle SQL servers) connections to our DMZ Servers. The connections drops often. On Some servers we cannot connect at all. But nothing at all in the logs, no drops.
After we disabled "inspect sqlnet" it works fine. But that's may not the way it should be.
Has anybody else problems with sqlnet and Release 22.214.171.124? With Release 8.0.2.x it worked fine.
To enable Oracle SQL*Net application inspection, use the inspect sqlnet command in class configuration mode. Class configuration mode is accessible from policy map configuration mode. To remove the configuration, use the no form of this command.
We are running 8.0.4 and we are also experiencing problems with the SQLNET inspection. My firewalls are in context mode and failover are active/active. We are able to connect to a DB and open a his table through SQL Net Client but if we used ODBC Connector, it's not working. We can connect to the DB but are unable to open tables. The result his a status message, ORA-03123, from Oracle. If i disabled SQLNet inspection everything his working fine.
