Mix of oracle client versions

[Former Member]

Hi All,

We have an ECC 6 system with 6 app servers with oracle 11.2. and 10.2.0.4 client for DB V11.2.0.2,  does anyone know of any issue with having multiple oracle clients.

Thank you

Hi Jonu,

There arent any issues that you would face with having multiple oracle clients on a single host.

In an ABAP system, Oracle client is determined by the environment variable setting of <SID>adm in dbenv* profile files.

Please refer note 819829 for more details.

Thx Renu

I found an SAP note 819829 which says : All SAP application servers of an SAP system should run with the same version of the instant client. Running a mix of different instant client versions in one SAP system is not recommended.

So wanted to check the reason for not having a mix of different client versions.

Thank much

Hi Jonu,

It might be due to the fact that you need to have a correct dboraslib.dll (part of kernel) and matching Oracle client library (oci*.dll included on Oracle Instant Client).

As the kernel remains same for all the Application servers, so should be the client.
