Thanks Matt, that was pretty enlightening. Now I’ve got a few more questions J and I guess you or Robert can address this quite easily.
What was the instability issue observed when running behind Apache? And how or what way has IIS improved the stability? While scanning through the archives I also came across this “CPU and database I/O is key. Witango doesn't use the disk much, and as a 32-bit application, can only address 2 GB of memory.( https://www.mail-archive.com/[email protected]/msg21836.html)”Whereas for my app it seems anything beyond 1GB and the instances start acting up and bring the application down pretty soon (as soon as 900 Mb-1GB mark is reached). I have been contemplating to make use of multiple instances of Witango 5.5 / Terascript in 1 physical server running behind 1 Apache and even that is not recommended (as I see from your response). Why is it so? I do know that clients.ini does the job of load balancing but since the thoughts are now hovering around having a couple more instances in each physical server, it made me ponder whether the traffic can be balanced even if 2 instances are running on the same machine (given that clients.ini does IP based load balance). My aim is of having 2 instances of T5.5 behind 1 apache / physical server. Is this achievable? Will this better my app’s performance?

Hi, Prabakaran. We have run multiple Witango 5.5 server instances in Windows 2003. We have one web server behind a load balancer that has a hot-swap web server in waiting in case that one crashes. This singe web server sends Witango/Terascript requests to one of two physical app servers, each with 6 Witango/Terascript instances. Robert can surely provide a more technical answer but in our experience the load is spread evenly across all the app server instances. I imagine the client.ini handles this. I don't know if there is any logic to it, but rather the order of the servers listed in the client.ini are simply round-robin'd. We've updated most our servers to T6, where we also run multiple app server instances per server. We're running everything on Windows 2008 servers now and I'm actually in the process of testing a build on a Windows 2012 server. We had Terascript6 running behind an Apache (for Windows) web server but experience some instability. Since moving to IIS on Windows, per Robert's suggestion, we've been running smoothly. We are in the process of following Robert's suggestion of moving toward multiple web/app server instances instead of multiple app servers instances per box. It will require us rearchitecting a few things since the webroot/htdocs directory will be on multiple servers. Probably more than you wanted to know but thought I'd share with the list how W5.5/T6 is being deployed at our shop. - Matt [email protected]<mailto:[email protected]> writes: Hi there, Can we run multiple processes of Witango 5.5 server in Windows 2003 server? If this can be done, can the load balancing be done between the processes thus bringing better stability to the app?
