Oracle 9i server connectivity with Oracle 11g client.

Hi,

We are going to upgrade the application server which is hosting the DB client with version 11g. I am trying to find the compatibility between Oracle 9i server(9.2.0.5) on AIX 5.3 with Oracle client 11g(11.2.4.0) on Windows 2012 R2. Please let me know if this connectivity is supported.

Hello,

Since 9i is desupported since years, I think,  it was never supported with 11g Client.

But I think it can work.

Another point: I think AIX 5.3 isn't supported longer by IBM?

If you're going to upgrade the application tier, then upgrade the database tier at the same time. There are bad issues with 11g/12c clients connecting to 9i databases.

Cheers,
