please, advice before apply DSTv41 patch
I have a Linux 7. 9 Server with three oracle19c stand alone instances, each one have diferente character set (WE8ISO8859P1, AL16UTF16 or UTF8), there are no schemas with columns or fields that use data TIMESTAMP WITH LOCAL TIME ZONE or TIMESTAMP WITH TIME ZONE.
The timezone version installed is 32 and oracle recomendation is Applying the DSTv41 update for the Oracle Database (Doc ID 2930097.1) because the server is in México and there the DST criteria have changed
My questions are:
Are there another warning to attend before aplying the new patch?
Whichs poblems could happen after update the patch?
