###sampe 1: 安装GI 失败，如何回退GI SOFT

GOAL

In 11gR2, deinstall is the recommended tool to deinstall an Oracle Clusterware(Grid Infrastructure) home, however it does not apply to certain scenarios or failures in some cases.

This notes provides instruction to manually remove current/active clusterware home.

Before removing current/active clusterware home, it's necessary to deconfigure Grid Infrastructure, refer to note 1377349.1 for steps.

To remove pre-upgrade clusterware home after successful upgrade to newer GI version, refer to note 1346305.1

SOLUTION

Before removing current/active clusterware home, it's necessary to deconfigure Grid Infrastructure, refer to note 1377349.1 for steps

To remove a home, as clusterware user execute the following on any node:

export ORACLE_HOME=<clusterware-home>

## detach ORACLE_HOME
$ORACLE_HOME/oui/bin/runInstaller -detachHome -silent ORACLE_HOME=$ORACLE_HOME

## confirm $ORACLE_HOME is removed from central inventory:
$ORACLE_HOME/OPatch/opatch lsinventory -all

## remove files in ORACLE_HOME manually on all nodes
/bin/rm -rf $ORACLE_HOME               ##>> if grid user fails to remove all files, switch to root user

unset ORACLE_HOME

If it fails for any reason, as clusterware user execute the following on all nodes:

export ORACLE_HOME=<clusterware-home>

## detach ORACLE_HOME
$ORACLE_HOME/oui/bin/runInstaller -detachHome -silent -local ORACLE_HOME=$ORACLE_HOME

## confirm $ORACLE_HOME is removed from central inventory:
$ORACLE_HOME/OPatch/opatch lsinventory -all

## remove files in ORACLE_HOME manually
/bin/rm -rf $ORACLE_HOME               ##>> if grid user fails to remove all files, switch to root user

unset ORACLE_HOME
