Is it recommandable that oracle client 126.96.36.199 can be used to connect to Oracle database 9.2.0.x ? We are searching latest Oracle client version that can be used to connect to Oracle 9.2.0.x.
I heard that Oracle client 188.8.131.52 is not certified to connect on Oracle 9.2.0.x. & Oracle Corp will not support this configuration and Oracle client 10.2.0.5 can be used to connect to Oracle 9.2.0.x.Is it true ?
Yes it is true. 9.2 is not supported to connect 11.2. See Client / Server / Interoperability Support Matrix For Different Oracle Versions [ID 207303.1] if you have MOS access for full details. Aka 10.2 supported only.
But in the past there was a rule that two main versions backward should work... (in this case 9.2 may work as well)
