RE: Number of Data Queue entries

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

András,
Consider coding this as a normal part of you DtaQ reader process. If you see
entries growing larger than your desired threshold, start another instance
of the reader program to help process the backlog. When workload goes down
again, the additional job/jobs can be ended. I'd use a data area or user
space to keep track of the reader jobs that are activated.

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.

All,

thanks for your comments. :)

Andras
