Virtual memory is disabled by the hoster in one of the Windows VServers I use to avoid heavy disk access. At the same time, the RAM provided is only 1GB, which is insufficient for an application I'm using.

I'm familiar with the RAM access pattern of this application, the CPU and RAM throughput is very low, but the amount of RAM required is large.

Is there a way to manually provide virtual memory to Windows so the application is able to run at all? From my point of view, anything is sufficient, be it from the local disk or via network (even though I think that it's getting perverted there).

You disabled virtual memory and you want virtual memory. Enable it again. – gparent May 23 '12 at 14:21

I don't understand this question - you've disabled the page file (Which, to my knowledge, isn't recommended practice even in a virtual environment) and now you're asking how you can provide a page file?

Why don't you just re-enable the page file on this one server, and set the size manually?

Because I have no control over the page file, the hoster does. – mafu May 23 '12 at 14:24
@mafutrct Get more RAM or get them to enable Paging. Or rewrite the program to not use so much RAM, especially if it's all idle all the time. – Chris S May 23 '12 at 14:31
@ChrisS: I wish I could - they already declined my inquiry. Rewriting the program is impossible, too. Only option left would be to pay for more RAM. – mafu May 23 '12 at 14:42
Only option left would be to pay for more RAM or terminate your contract with them and engage someone competent. – RobM May 23 '12 at 14:45
You do realize that even if you get the application to run, it will be slow right? Unless your app is reserving a gigabyte of zeros, chances are you'll start swapping very quick. The right solution when you don't have enough memory is to get more memory. – gparent May 23 '12 at 17:36
