Hi erman,

We are upgrading from 11.1.0.7 to 11.2.0.4
We have installed 11.2.0.4 and applied OCT2020 PSU.

We are referring to to avoid any performance issues during the upgrade --> "Things to Consider to Avoid Poor Performance or Wrong
Results on 11.2.0.4 ( Doc ID 1645862.1 )"

Bugs:

Document 18255105.8 Patch for upgrade scripts to identify histograms affected by fix of bug
15898932
NB: Apply before running the 11.2.0.4 upgrade script. There is no benefit to applying later on.

Document 19855835.8 Upgrade slow when reorganizing large stats history tables
NB:Apply before running the 11.2.0.4 upgrade script. There is no benefit to applying later on.

It says apply patches relevant to your psu.But our psu version is not listed.

We need your help to which patch should we apply. Patch 21392660 for 11.2.0.4.0 OR Patch 21765124 for 11.2.0.4.4 (We have applied
OCT2020 PSU)

Thank you
