Do not upgrade to Discoverer 10.1.2.3

October 2008 Important Update: Oracle released CP2 for 10.1.2.3 on October 3, 2008

I urge you not to stay on the non-updated base install of 10.1.2.3. You should apply CP2 or CP1 as soon as you can (link to patches)

I have recently been contacted by someone asking for help with Discoverer 10.1.2.3 - 10.1.2.55.26. I'm guessing most of you never even knew that it had been released. There was certainly no big splash about this anywhere that I have seen.

Anyway, it was released 0n 07-MAR-2008 as part of Application Server 10g patch set 3, which you can find on MetaLink as patch number 5983622. This is a major patch and can be applied on top of 10.1.2.0.0, 10.1.2.0.2 or 10.1.2.2. However, when it was first released it was very buggy which is why both Oracle and myself were recommendingyou should not apply it at that time.

Happily, you are safe installing 10.1.2.3 so long as you apply at least CP1.

However, if you are using E-Business Suite, Oracle is still not recommending customers not to upgrade to Discoverer 10.1.2.3 because:

• 10.1.2.3 is not yet certified with E-Business Suite 11i or 12. This work is currently in progress and the appropriate notes will be updated when the certification is complete.

Therefore, if you have already upgraded to 10.1.2.3 you need to reverse that and get back to a stable version of 10.1.2. At that point, if you have not already done so, you need to upgrade to 10.1.2.2 (patch number 4960210) and then apply the latest 10.1.2 cumulative patch. As of the date of this posting this is CP8 which was released during July and August 2008. You can find it on MetaLink as patch number 7306816 (if on Linux, Solaris or HP) or 7111816 if you are using Windows.

Optionally, especially if you want to interface Discoverer 10g with BI Publisher you will need to also apply the web services patch which for CP4 and above is 6622352.
