How to increase thread count in glog.properties file?

Does anyone know how to increase thread counts for SMTP, HTTP, and OMD in the glog.properties file?

The only properties I could find are in the glog.base.properties file:

glog.process.threadGroup.mail=1
glog.process.threadGroup.httppost=1

Are these the right ones to update? Which property is it for OMD?

Thanks in advance!

Re: How to increase thread count in glog.properties file?

Here is the OMD one:

!remove glog.workflow.topicGroup=OMD,2

The ones for HTTP are
glog.base.properties:glog.workflow.topicGroup=http ,4
glog.base.properties:glog.process.threadGroup.http post=1

The one I will tell you NOT to increase is the smtp one. There really is no need to increase this and if you have a problem it is usually with your SMTP server. Increasing this may cause system instability.

Re: How to increase thread count in glog.properties file?

Thanks Nick! Is it unusual to have a SMTP thread process for roughly 30 seconds by one outbound tender? I'm seeing a processing time average of 6.4 seconds, with a longest processing time of 120 seconds.

This is what I'm seeing here. So, for example, if we tender out 50 tenders at a time and it is taking about 30 seconds for each to process then the last e-mail won't go out until about 50 mins later. By the time the carrier is getting the e-mail, the shipment may have timed out. In any case, I was wondering what is typical (or good) for processing times for the SMTP thread? Thanks again!

If tenders are taking 50 minutes to get to your inbox, I think there is a problem with the SMTP server. A message should take at most 4-5 seconds to process. If it is taking longer there is a problem with the application or something external from the app. If the backlog clears quickly then it is a problem with the SMTP server or the way they throttle emails.
