RE: Oracle and DST changes

I don't think 1 & 3 are contradictory. I think the key difference is that #1 says if the dict columns do not use affected time zones, the patch is not needed. #3 says if the dict columns do use the affected time zones, then the patch is needed.  

For a better explanation of affected time zones (and affected time frames), see 402614.1.

ok,here's the entire blurb from 359145.1

In Oracle10 the data dictionary uses TSTZ types. Therefore it is more likely that affected data is used:
1. If no TSTZ or TSLTZ types are used outside of the data dictionary, and the TZ_OFFSET function is not used, and the dictionary TSTZ columns do not use the affected time zones, the patch is not needed. 2. If TSTZ or TSLTZ types or or the TZ_OFFSET function are used outside the dictionary, but do not use the affected time zones, and the dictionary TSTZ columns do not use the affected time zones either, the patch is not needed.
3. When any data, either in the dictionary or in the user data or in the usage of time zones in PL/SQL, uses the affected time zones, then the patch is needed.

Is it just me, or does #1 contradict #3 ? ? ? And what exactly is affected time zones. I thought it was an area of the U.S. where the time zone change will occur. But #3 says "when data . . . uses the affected time zones" I interpret this to mean when there is some code using the TSTZ or TSLTZ.

I'm with Tom on this one. We have JVM installed, but no Java procedures. I'm interpreting this to mean I don't need the patch.

This is about as clear as mud to me . . .

        Tom, not sure if you saw this post yesterday, but Metalink 359145.1 seems to say that you do need to patch 10g even if you're not using the TZ data types:                   

        "When any data, either in the dictionary or in the user data or in the usage of time zones in PL/SQL, uses the affected time zones, then the patch is needed."                   

        I also checked my 10.2.0.2 dictionary and there are 149 columns using the TZ data types. Please let me know if I'm missing something though, because I'd rather not install the patch if I don't have to.
