I wanted to respond to this thread, with some very interesting stuff I have learned recently. The issue is, it is one of my longer type posts, and includes some graphs from my zabbix monitoring system. So I was planning to create a html page or something and link to it, but I just haven't had time. But since I have posted the link now to

http://devcom.bighead.net/

I went ahead and posted on there, where it is very simple to format, and add images and such. I think it is some valuable information regarding this thread, and also dealing with persistant connections, caching, and datasourcelife and the like.

Here is a direct link to the post.

I have seen that, it happens during heavy traffic, and witango will just keep loading up a DB. I can post more detail on this information tonight, too busy now.

How did you get 200 connections? The most we get on one Witango server at one time is 9.

A datasourcetimeout of 15-60 minutes is acceptable. All this means is that during times of no/lower activity unused connections will be closed to free up resources.

Each ODBC connection consumes memory (about ½ MB I think), today’s servers have no problems juggling 10s or even 100s of them. As I write this there are over 200 connections between my Witango services and my SQL server. The nice thing is that if Witango needs to ramp-up to 20-30 connections to service some peak traffic, most of them will timeout during low traffic. Refreshing ODBC connections can be healthy as well. Especially if you have a problem with your SQL server or network, Witango will need to kill off all active connections and make new ones.

For you second question, use @HTTPATTRIBUTE to look for these bots at the top of your TAFs and send back a handmade 404 error.

Subject: Witango-Talk: datasource timeout

Hi,

2 questions:

Question 1:
On our win2003 box running Witango 5.5, we noticed we have DATASOURCELIFE=1440, a carry over from when we used to run RTango2000 and Oterro ODBC. Has any one run into any problems running the datasourcelife at its default of 30? Our website is getting hit constantly by bots and wondering if lowering the datasourcelife would increase proformance.

Queston 2:
Related to question 1, in the iis logs, there are a lot of entries that have “lwp-trivial/1.41” or “LWP::Simple/5.805”. Does anyone have a recommendation on how to handle them. They are hitting the site about every 3 seconds.
