Current Interoperability Support Situation
The matrix below summarizes client and server combinations that are supported for the most commonly used product versions. A full matrix appears at the end of this document.
New interoperability problems will only be investigated if BOTH releases involved are covered by a valid support contract at the time that the issue is reported. For example:
A 11.1.0 client to an 11.2.0 server issue requires the customer to have a valid Extended Support contract for the 11.1.0 client in order for Oracle to investigate it.
- #1 - See Note 207319.1
- #2 - An ORA-3134 error is incorrectly reported if a 10g client tries to connect to an 188.8.131.52 or lower server. See Note 3437884.8 .
- #3 - An ORA-3134 error is correctly reported when attempting to connect to this version.
- #4 - There are problems connecting from a 10g client to 8i/9i where one is EBCDIC based. See Note 3564573.8
- #5 - For connections between 10.2 (or higher) and 9.2 the 9.2 end MUST be at 184.108.40.206 or higher. Connections between 10.2 (or higher) and 220.127.116.11, 18.104.22.168 or 22.214.171.124 have never been supported.
- #6 - For connections between 11.1 (or higher) database server and 10.1 / 10.2 database server across a database link the 10g end MUST be at 10.1.0.5 / 10.2.0.2 (or higher) respectively in order to use PLSQL between those versions. (This does not apply to normal 11g clients to 10g database server only server to server and a few very specific client products, such as Oracle Forms). See Note 4511371.8 for more details.
- #7 - For database link connections between 11.1 (or higher) and 10.2 the 10g end MUST be at 10.2.0.2 (or higher) in order to use PLSQL between those versions. See Note 4511371.8 for more details.
- #8 - Attempting to connect from 9.2 to 12.1 will fail with an "ORA-28040: No matching authentication protocol" error.
- #9 - 126.96.36.199 or 188.8.131.52 only. We do not support any 11.2 client interoperability with Oracle Database Exadata Express Cloud Service
- #10 - Includes Oracle Database Exadata Express Cloud Service - see Note 2183770.1 for additional details.
- #11 - For the IBM z/OS platform only, Oracle will continue to test past 2014, at its discretion, new versions of the database running on non-z/OS platforms with the older 10.2 client running on z/OS. For more information, please refer to Note 461234.1 - Oracle Database on z/OS Support Status.
- For database links between different Oracle versions connections must be supported in BOTH directions in the matrix above.
eg: As 11.2 -> 10.1 is not supported then database links between these version are not supported in either direction.
- Unsupported combinations may appear to work but can encounter errors for particular operations. The fact that they appear to work should not be relied upon - issues on unsupported combinations will not be investigated.
- Since new database servers are compatible with a limited set of older OCI clients, it may not be necessary to upgrade the client software when upgrading the database. However, some new features may not work without upgrading the client software. For example, an Oracle 10.2 client is able to connect to an 11.2 database, but is not able to take advantage of newer features such as Client Result Cache (introduced in 11.1).
- Oracle Applications , or other Oracle products, may have supported configurations not listed in the matrix above.
- The matrix above also applies between different platforms and between 32/64 bit releases of Oracle client / server except where any Oracle platform desupport notice indicates otherwise.
- Unix BEQUEATH (BEQ) connections are NOT supported between different releases. eg: Client 10.2 is not supported to make an Oracle Net connection to a 11.2 server using the BEQ protocol adapter regardless of the interoperability support listed above. See Note 364252.1 for more details.
- "Oracle Client" product interoperabilities expressed in this document do not extend to other client products, such as the "Sql-plus Instant Client" product.
