Checking logging is running for a particualr instance on a

Does anyone know of a good way of checking logging is running for a particular instance for a multiple instance environment so that I can automate the checking in a script. 'ps -ef | grep ontape' returns 2 ontape -c processes with the same owner. If only one process was running I'm not sure I'd know which instance has dropped out. onstat -l could do it but would only show after a period of time if logswere not being backed up and would require many repeat checks for confirmation None of the other onstat flags seem to tell you whether logging is running or not Any help would be much appreciated Paul Matthews
