sqlnet interoperability matrix- for the new oracle dba





you are a new oracle dba and you know that oracle sqlnet is the component that is present in the oracle client as well as the oracle server.when oracle client wants to communicate with the oracle server then the sqlnet component of the oracle client communicates with the sqlnet component of the oracle server. Below is the supported versions matrix from oracle metalink.

Server Version

Client Version 11.2.0 11.1.0 10.2.0 10.1.0 9.2.0 9.0.1 8.1.7 8.1.6 8.1.5 8.0.6 8.0.5 7.3.4

Key:

Yes Supported
LES Supported but fixes only possible for severity 1 issues for customers with Extended Support . Limitations apply – see click here for policy details for 9.2.
ES Supported but fixes only possible for customers with Extended Support .
Was Was a supported combination but one of the releases is no longer covered by any of Premier Support , Primary Error Correct support , Extended Support nor Extended Maintenance Support so fixes are no longer possible.
No Has never been Supported

 

Specific Notes:

  • #1 – See Note:207319.1
  • #2 – An ORA-3134 error is incorrectly reported if a 10g client tries to connect to an 8.1.7.3 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 9.2.0.4 or higher. Connections between 10.2 (or higher) and 9.2.0.1, 9.2.0.2 or 9.2.0.3 are not 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.

General Notes:

  1. 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.
  2. 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.
  3. 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. So, 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).
  4. Oracle Applications , or other Oracle products, may have supported configurations not listed in the matrix above.
  5. 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 .
  6. 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.
