A How to Stop Processes in an Existing Oracle Real Application Clusters Database

This appendix describes how to stop all processes in an Oracle Real Application Clusters (Oracle RAC) database, in preparation for installing Database Vault.

Note:

Before you make any changes to the Oracle software, Oracle recommends that you create a backup of the Oracle Database installation.

To stop all processes in an Oracle Real Application Clusters (Oracle RAC) database, use the following steps:

Note:

You must perform these steps in the order listed.

Make sure that the environment variables, ORACLE_HOME, ORACLE_SID, and PATH are correctly set.
Shut down any processes in the Oracle home on each node that can access a database. For example, you need to shut down Oracle Enterprise Manager Database Control.
```
$ORACLE_HOME/bin/emctl stop dbconsole
```
Note:
- You must run the preceding command on all nodes.
- Before you shut down any processes that are monitored by Enterprise Manager Grid Control, set a blackout in Grid Control for the processes that you intend to shut down. This is necessary so that the availability records for these processes indicate that the shutdown was planned downtime, rather than an unplanned system outage.
Shut down all Oracle RAC instances on all nodes. To shut down all Oracle RAC instances for a database, enter the following command, where db_name is the name of the database:
```
$ oracle_home/bin/srvctl stop database -d db_name
```
