Greetings, This is interesting. We have an application that uses .NET and we were noticing performance degradation using ONAMES. The vendor indicated that .NET performs much better with TNSNAMES as opposed to ONAMES. Do you have more information about this particular bug? Thanks.

I don't know about 9.2.0.8, but with 9.2.0.6 it has been necessary to use a local tnsnames.ora file here when the client is Java and/or .Net. These tend to make a number of connections to the database, and a bug in the 9.2 client causes name resolution to periodically fail.

The error I get is 3113 but there is no accompanying error on the 9.2 server side. I am unable to find any bug filed about that. Has anybody else seen things like that? Unexplicable 3113 errors without a trace on the server side? It happens only when different major versions of the database are involved. -- Mladen Gogala Sr. Oracle DBA Video Monitoring Systems 1500 Broadway New York City, NY 10036 Phone: (212) 329-5201 Email: mgogala@xxxxxxxxxxx -- Jared Still Certifiable Oracle DBA and Part Time Perl Evangelist
