Hi Again
I will mention steps to shutdown Oracle Real Application Cluster First :
You need to shutdown all the services like the following :
On Linux :
**Change to $ORACLE_HOME/crs/bin
shutdown emctl stop dbconsole .
1- ./srvctl stop database -d .
To check database name :
select DB_name from v$database ;
2-./srvctl stop asm -n
To check node name :
Hostname on terminal .
3-./srvctl stop nodeapps
4-./crsctl stop -all
these steps to stop RAC services on linux :
Windows :
** change to $ORACLE_HOME/crs/bin
1-srvctl.exe stop database -d
2-srvctl.exe stop asm -n
3-srvctl stop nodeapps
4-crsctl.exe stop -all .
Startup RAC services :
1-./srvctl start nodeapps
2-./srvctl start asm -n .
3-./srvctl start database -a .
4-./crsctl start -all .
emctl start dbconsole .
windows the same but without “./” just srvctl.exe
