RE: [MS_AccessPros] Re: max users linked


Glenn - Yes, that's exactly what happens. When I was developing my ShowUserRoster add-in I spent a lot of time studying locking files (you can open them in notepad). If a user logs out and then back in before the file is killed his name shows up a second time in the file.

Your reply to Liz prompted a question for me. If Joe and I connect and then I disconnect as you have described, if I reconnect, does the locking file use my original connection or does it count the new instance of me as yet another user?

255 (or maybe it's 256) is the maximum number of connections that the locking file can handle. If I connect and then Joe connects and then I close out the locking file still shows me as connected until the locking file is killed. So you can see how the connections can quickly hit the max. When I design an application I'll use an Access back end if I have 30 or less concurrent users. Any more than that and I switch to a SQL back end. You can have thousands of concurrent users in SQL...not that I've ever had THAT big of an audience. I think my biggest is around 150.

Pros, I have multiple users linking to the same back end database from different local front ends.

Is the max 255 for v 2010?
