Rebooting RAC servers

For some maintenance activity, if RAC servers need to be rebooted then the steps are:

1. Check the status of all the services
[oracle@naikh] cd $CRS_HOME/bin
[oracle@naikh] crs_stat -t

2. Stop the database
[oracle@naikh] srvctl stop database -d orcl

3. Stop nodeapps
[oracle@naikh] srvctl stop nodeapps hostname1
[oracle@naikh] srvctl stop nodeapps hostname2

4. Reboot the servers
Ask System admin to reboot the both the servers

5. Once the server is up check the status of all the services
[oracle@naikh] cd $CRS_HOME/bin
[oracle@naikh] crs_stat -t

6. Start the nodeapps if not automatically started.
[oracle@naikh] srvctl start nodeapps hostname1
[oracle@naikh] srvctl start nodeapps hostname2

7. Start the database if not automatically started.
[oracle@naikh] srvctl start database -d orcl

8. Make sure all the services are active
[oracle@naikh] cd $CRS_HOME/bin
[oracle@naikh] crs_stat -t

Managing RAC Instances

1. Status of all RAC instaces
[oracle@naikh] srvctl status database -d testdb

2. Start all RAC instances
[oracle@naikh] srvctl start database -d testdb

3. Startup one RAC instance
[oracle@naikh] srvctl start instance -d testdb -i testdb1

4. Shutdown one RAC instance
[oracle@naikh] srvctl stop instance -d testdb -i testdb1
