Does anyone have any experience with running Advanced Revelation applications under Windows2000 Terminal Services? I'm looking for any suggestions or warnings.

There are generally two main issues you need to work with, at least on Citrix. Win2K/TS is not much different from this, so a little searching around Citrix's site will give you some good information.

The things you need to check are registry settings for 16 bit apps or DOS apps and watching the processing resources used by the ARev sessions. ARev 3.12 yield should handle this somewhat, as will Steve Smiths CPUPlus program and Citrix's tame.exe.

Mr. Spress,

We don't have Windows Terminal Services, but am curious. Would this apply to OI as well being that it's 16 bit.

Thanks,

Ray

Not the same problem (16-bit) exactly. The problem with AREV is its abuse of the timer. It just sits there polling for keystrokes and allows for background indexing to proceed. This can cause Citrix and / or Terminal Server to saturate very quickly. The Citrix Tame program helps this somewhat, but Steve Smith's CPU Plus is even better since it replaces several offending AREV routines with better pieces of code. OI is much less irritating since the only thing doing real work is Open Engine which doesn't grab the keyboard directly.

Don,

Thanks for your response.

I finally installed the NT services (under Window NT) here and setup OI to run with multiple users via the Server Deployment solution. Now the document says that thing will be slower with the Nt services than under the NLM, but man is it slow. I've tried some fine-tuning maybe a little better, but it's still not very satisfactory ;-(

Do you thing (or know) that OI will perform more speedily under Window Terminal Servers with Metaframe or using some flavor of Citrix using ICA. I'm going to have to cross this issue in the future and I'm searching for some practical solution to deploy our app under OI when it's done. If what I'm seeing with Windows NT and Nt service is how things will perform, we need some HELP!

At present, I don't have Terminal Server or Citrix Winfram available. Any comments or suggestion from anyone is appreciated.

Thanks,

Ray

My take is that Citrix or Terminal Server is less predictable in performance than NT or Novell (NLM). Mostly it has to do with the way that the virtual machines are time-sliced across the bus. I have a client that is using a MetaFrame (Citrix) with an AREV 3.12 app with about 10 users. Sometimes it runs great other times it seems to vanish into the woods, perhaps to have lunch. It seems to revolve around what else is going on as well. It is very easy to saturate the LAN connection if the Citrix box is running as a Client on NT. I'm trying to get them to try Steve's trick.

I have another client who uses Terminal Server with my OI app. Since OI is essentially slower than AREV anyway, the NT service is a mandatory choice on the server. The app seems too jerky for my taste, but I'm loading a lot of picture info in this app. Some of the BMP pics are 200-300K and it seems to stop and start as the processor time-slices.

Well, we're not using Terminal Server just regular NT with NT Services and I think that OI runs "too" slow for my preference. Our PCs here range from 500mhz, 200 mhz, 133mhz and 75mhz . I was hoping (wishfully) that OI can be made to look more snappy using NT services with something – Citrix, Metaframe, whatever
