Oracle Shutdown Immediate Waiting On Active Process

Oracle Shutdown Immediate Waiting On Active Process

Usually whenever you trying to shutdown an Oracle database with immediate option, it will wait for some active process to get terminate. This may take long time and it also depends on the number of processes.

use below command to find out the active sessions on database:

bash-3.00$ ps -ef | grep LOCAL=NO

You need to kill the process only with option LOCAL=NO. The below is the very useful UNIX command which can be used for killing these idle active session on database which are avoiding the database to shutdown with immediate option.

kill -9 `ps -ef | grep LOCAL=NO | grep <INSTANCE NAME> | grep -v grep | awk '{print $2}'`

Now, verify the processes again with ps -ef | grep LOCAL=NO it should not return any list, If these processes are killed successfully then the database will shutdown smoothly.

Note: It is strongly recommended to do on Test Instances before executing on Producion.
