Oracle : Ошибка ORA-15028

"ASM file '%s' not dropped; currently being accessed"
*Cause: An attempt was made to drop an ASM file, but the file was
being accessed by one or more clients and therefore could
not be dropped.
*Action: Stop all clients that are using this file and retry the drop
command. Query the V$ASM_CLIENT fixed view in an ASM instance
or use ASMCMD LSOF to list active clients.
