"cannot SHUTDOWN ASM instance with connected client (process %s)"
*Cause: A SHUTDOWN command was issued to an ASM instance that had one or
more connected clients.
*Action: Stop all clients that are using this ASM instance and retry the
SHUTDOWN command. Alternatively, use the SHUTDOWN ABORT command.
Note that issuing the SHUTDOWN ABORT command to an ASM instance
results in abormal termination of all RDBMS instances connected
to that ASM instance. One of the active clients has been listed
in the error message. Query the V$ASM_CLIENT fixed view in an
ASM instance or use ASMCMD LSOF to list all active clients.
