If you want to shutdown backup server also, make sure too shut it down first, as you will not be able to login to isql if you shutdown main server first.
Login to isql to shudown the ASE database and issue command “shutdown”
Then you can shutdown the ASE database instance.
You can opt to kill the processes (For example: If you dont have password to login to isql). But this is not the most safer way. Please use this option only if you are not able to login to isql.
Dont use -9 option. This might not allow uncommited DB transactions to rool back in a proper way.
