RE: Oracle and DST changes

I hope I'm not beating this subject to death, but it seems a lot of people are interested in it so here is another thing I found interesting. The 10.2 patch (5601428) for installing the new utltzuv2.sql and timezdif.csv files (which are just for checking to see if you have affected data, not for actually fixing it) says the following in the README.TXT file:

# Patch Special Instructions:
# ---------------------------
# Make sure all instances running under the ORACLE_HOME being patched
# are cleanly shutdown before installing this patch. Also ensure that
# the tool used to terminate the instance(s) has exited cleanly.
 

Now, why would you have to shutdown your instance just to install this SQL script and CSV file? Of course I didn't want to shutdown my instance, so I just extracted the .sql and .csv files and put them in the correct directories ($ORACLE_HOME/rdbms/admin & $ORACLE_HOME/oracore/zoneinfo, repectively) and then I ran the script and it worked just fine - returning no affected data, as expected.  

I don't have a lot of experience with patching, so maybe I'm missing something here. Can someone please tell me if there is some reason why I should install this patch instead of just manually extracting the files, and if so, why this simple patch would require the instance to be shutdown, or is that just standard procedure that you have to shutdown for all patches, even if it's not really necessary?  

Thanks,
Brandon

I saw that and reran the utltzuv2.sql file against my 10g database (10.2.0.2) and it reports nothing to be concerned about.
