7.1 Overview of Deinstallation Procedures

There are several tasks to perform when completely removing all Oracle databases, instances, and software from an Oracle home directory.

• Identify all instances associated with the Oracle home

• Shut down processes

• Remove listeners installed in the Oracle Database home

• Remove database instances

• Remove Oracle Automatic Storage Management (Oracle ASM) release 11.1 or earlier

• Remove Oracle Clusterware and Oracle ASM (Oracle Grid Infrastructure)

Note:

• For information on removing Oracle Database Vault, see Oracle Database Vault Administrator's Guide.

• For information on removing Oracle Configuration Manager, see Oracle Configuration Manager Installation and Administration Guide.

• With Oracle Grid Infrastructure 11g release 2 (11.2) and later, Oracle ASM and Oracle Clusterware comprise the Oracle Grid Infrastructure installation. These components are installed and removed together.

Caution:

If any cluster member node has more than one database with the same global database name (GDN) on a server, then you cannot use the deinstallation tool to remove only one database.

For example, if you have a standalone database on one of your cluster nodes with the GDN mydb.example.com, and your Oracle RAC database GDN is also mydb.example.com, then both databases on that node are removed by the deinstallation tool.
