10.2.0.1 DST patchset

I will attempt to summarize what I have gleaned and applied.  

There is no official patchset for utltzuv2.sql, patchset 5601428 before upgrading.   

There is however a 10.2.0.1 4689959 patchset for the timezone files.

After you check and save your data with the utltzuv2.sql 5601428 script (that you applied manually, note 399832.1), you apply the 4689959 patchset for 10.2.0.1 using opatch. Doing this will update the 10.2.0.1 opatch inventory showing that 4689959 has been applied. It will Not show 5601428 was applied. Then restore the data and cleanup as described in note 399832.1  

Note: I cannot remember if I used 10.2.0.1 opatch or 10.2.0.2 opatch to apply the 10.2.0.1 4689959 patch. (someone remind me).  

However when finished, you do have to use the 10.2.0.1 opatch executable to see this the 4689959 inventory listed.  

IF, before you start this, you had applied 10.2.0.2 already on the server for a 10.2.0.2 database, the 10.2.0.1 opatch will not show either patchset, but the 10.2.0.2 opatch will indicate that both patches have been applied.
