Question

We have an application (well, 3) which uses Oracle 9i, however this is being end-of-life-ed shortly, and we need to move to another platform – Oracle 11 or Postgress being the obvious ones.

I’ve heard comments to the effect that porting from 9i to 11 isn’t straight forward, but no-one here can confirm one way or the other. I’m not overly concerned with ‘oh, the query plan engine changed’, I’m more concerned with ‘this feature isn’t there anymore’.

None of the apps are complex – it’s either basic crud stuff in client-side SQL (and a big multi-table search routine, but we are going to rewrite that using Lucene anyway), or the same in PL/SQL.

Postgress only came up as a possibly easier and cheaper target to port to, but the license cost is offset by the training cost for our DBAs.

Any experience comments appreciated.

Some things to note:

• CREATE VIEW privilege is part of CONNECT role in 9i. But not in 10g. Probably also in 11G. You may want to add a grant to your installation scripts.
• 11G has case sensitive passwords. So if you find yourself unable to connect this may be the problem.
