I have 5 databases on one server and I am having trouble starting up and shutting down databases as I need to with out effecting the other databases.

I am using the following command:svrmgrl
connect internal/sys@cmsdemo2
shutdown abort;
startup open pfile=c:\oracle\ora81\database\initcmsdemo2.ora;
shutdown;

If there is a more efficient way to shut down one database at a time or all at once, it would be appreciated.
