What versions of the OCI client libraries are supported with what versions of the database?
Client and server software is tested for compatibility when new versions are released. We test all new clients with old servers that, on the day the new client releases, are still within the Primary Error Correction phase of their support life. We also test new servers with old clients that, on the day the new server releases, are in the Primary Error Correction phase of their support life, or are in the first two years of the Extended Maintenance phase of their support life. If we do not test the combination, it is not supported. When 10.1 was released, client and server versions 8.1.7 and 9.2 were within their Primary Error Correction support life. Those combinations of client and server were tested and are supported. Version 9.0.1 was tested, but is not supported, since it does not have an Extended Maintenance phase. The matrix below summarizes clients and server combinations that were tested.
