Patching process with golden homes : An example ?

edited May 14, 2020 12:26AM in Database Administration (MOSC) 2 commentsAnswered ✓

Hello all,

i administer about 50 databases, most of them in the 12.x versions. I want to have separate oracle homes for different pach levels to keep the downtime short and for easier rollback.

For patching i followed the following steps :

BEFORE Downtime

  • Create a new oracle home with a new path unter .../product
  • rsync the  content of the old path to the new path with some exclusions
  • replace the OPatch directory in the new path with the newest release
  • Start clone.pl
  • Start  the root script
  • Apply the patches in the new oracle home
  • Modify the listener.ora in the new home so that it refers to the new home directory

Howdy, Stranger!
