I had shutdown the asm instance and the database but still i can see the above processes running, If i want to reboot the server i needed to stop these processes without using kill option. please help me how to stop the above processes for rebooting the server?
What you have to do is:
First of all, shutdown instances, ASM first and RDBMS in second place. After that you need to re-run the above command (crs_stat -t) to identify processes that still are alive.
Once you find them, run the following command:
Attempting to stop `ora.cssd` on member `test02`
Stop of `ora.cssd` on member `test02` succeeded.
The process 'ohas' (Oracle High Availability Service) runs at startup with respawn option, so, you cannot kill it. Normally it's safe to reboot your server with this process up.
