Similar to my earlier posting, I am cross posting this information to make it easier for others to find. [INDENT]When attempting to make a Database Connection to SDE 9.2 using Oracle 11g client, the following message appears:
Database Connection: Failed to connect to the specific server. Do you wish to continue? ArcGIS 9.2 geodatabases do not support direct connect using Oracle 11g clients. Please use the Oracle 10g client or the application server.
What is odd about this message is that it appears in ArcGIS 9.3/9.3.1 but went away with ArcGIS 10. Since connecting to SDE 9.2 using Oracle 11g client works in ArcGIS 10.0, it appeared the connection problem in 9.3/9.3.1 was really a client issue and not a server or SDE issue.
