Hay veces en la que es preciso quitar infraestructura que no usamos ya sea por que nuestro servidor se renovo y dejamos el hardware para uso de otras areas o por que se crear ambientes con versiones no compatible , hoy veremos como desinstalar el Oracle Grid Infraestructure 11gR2.

VAMOS AL PATH A BUSCAR EL DEINSTALL DEL CLUSTER

[oracle@datos0001lx grid]$ cd /u01/app/oracle/product/11.2.0/

HACEMOS LA BUSQUEDA DEL ARCHIVO DE DESINSTALACION

[oracle@datos0001lx 11.2.0]$ find . -name deinstall*
./grid/inventory/Templates/deinstall
./grid/inventory/Templates/deinstall/deinstall

./grid/deinstall/jlib/deinstall_core.jar
./grid/deinstall/jlib/deinstall_wrapper.jar
./grid/deinstall/deinstall.pl
./grid/deinstall/response/deinstall.rsp.tmpl

EJECUTAMOS LA DESINSTALACION

    Hola, que ocurriria si directamente hago un rm -rf del directorio grid???

    • Pablo:
      bajo que escenario lo harias ?
      Cual seria el estado de los procesos ?
      Cual seria el estado de la base de datos ?
      Ademas de ese rm -f como seguirias ?
      Con ello puedo responder tu pregunta.
      Saludos Cordiales.

    or large bowel diarrhea ( it originates from the colon).
    Curiously, many with ASD also suffer from gastrointestinal issues, like abdominal cramps and constipation. * It
