This document describes the procedure to remove the Oracle Grid 12c Home and ASM on Oracle Linux 6.5.
Starting with Oracle Database 11g Release 2 , Oracle recommends that you use the deinstallation tool to remove the entire Oracle home associated with the Oracle Database, Oracle Clusterware, Oracle ASM, Oracle RAC, or Oracle Database client installation. Oracle does not support the removal of individual products or components.
Identify all instances associated with the Oracle home that you want to remove.
[oracle@oracle123 ~]$ cat /etc/oratab
+ASM:/u02/app/oracle/product/12.1.0/grid:N
db11g:/u01/app/oracle/product/11.1.0/db_1:N
Oracle recommends to run the deinstallation tool as the Oracle software installation owner usually as oracle user.
After executing deinstall tool, it will prompt for enter LISTENER name, and for confirmation.
All info marked in RED will be prompted.
During execution it will generate a script to be executed as root user and then press enter to continue.
