Aplicación de "CRS Bundle" Patches con OPATCH AUTO

Recuerdo que la aplicación de patches “CRS Bundle” para una instalacion con Oracle RAC 10g R2 o superior era tedioso por la cantidad de pasos y consideraciones que se debia cumplir para CRS_HOME, ASM_HOME y DATABASE_HOME. No quiero decir que es complicado sino que habia que estar bien despierto para que no nos “perdamos” ni un paso.

Afortunadamente….

Oracle ha mejorado la forma de aplicar este tipo de parches a través de su tool OPATCH y ha incluido la funcionalidad OPATCH AUTO que realmente optimiza tiempo y esfuerzo ya que detecta y automatiza el proceso de aplicacion de un “CRS Bundle”

A continuación muestro mas referencia del comando, lo demás se encuentra en el README de los ultimos patches de “CRS Bundle”

Usage:
:
:  opatch auto -h       # to see this message
:
:  This command must be run as root user and needs Opatch version
:  10.2.0.4.7 or above.
:  Case 1 –  On each node of the CRS cluster in case of Non Shared CRS Home.
:  Case 2 –  On any one node of the CRS cluster is case of Shared CRS home.
