hi,

I have not install a patchset in a PRODUCTION Oracle DB,so would like to collect any feedback on the standard practices for doing that?
Because i understand a patchset installation require it to be performed on the current Oracle Home directory where the production binaries and I guess it's not wise to overwrite that current binary dir,was thinking :

1) of doing a wholesale cp of the current binary into the new patchset version directory newly created and perform the patchset installation there ?? OR

2) Installing the current binary version again in the new patachset version newly created and then perform the patchset installation there ??


Are those industry standard practise?? Any DBA gurus can enlighten?

thanks in advance
