RE: Number of Data Queue entries

[Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>]

One step further is to have a second reader program fire off.  Data queues
are great for processing FIFO on a many to many relationship.  Our reader
programs look at the time stamp of when an entry was posted to the queue.
If greater than xx seconds, submit another reader.  Of course we have on one
box we have 46 devices plus 3 web server that send to the queues and at
least 2 readers at all times.  Every time a new reader is started, it sends
a message to the operator stating so with the on queue time that signaled
the new reader to start.

Ken,

I never said I am storing data in data queue. We have a client-server 
application, one writes the data queue and the other reads it. The problem 
was, that the 'writer' program - accidentally - generated too many entries, 
and the 'reader' was not able to process them in time. As a result, the data

queue was overfilled.

I am thinking of a program which periodically - 15 sec, or so - checks the 
number of entries and can warn the operator in case a ceratin threshold has 
benn reached.
