Re: My token ring network croaked

[Chuck Lewis <CLEWIS@xxxxxxxxxx>]

Eric !

Where/how do you use this ? I see that the ENDJOB command has a field for this
information, but if the system is ending these jobs due to a communications 
failure,
how do you handle this ?

We have had the same thing happen. We have had a NIC start beaconing or have 
had a
frame realy failure OR the one of the NIC cards in our AS/400 has "burped" and 
all
of a sudden we have 400+ Client Access devices in the US and Canada 
failing/writing
MASSIVE job logs...

Thanks !

Chuck
