Max Files vs Max Guests

[Airborne]

FileMaker Pro indicates that you can share 1 file with 25 users, or 10 files with 10 users. Is there some sort of formula to determine the number of users to number of files?

 

I have an application that has 38 files. We tested this with 3 users, and it worked fine. I thought that we would be ok but when we deployed, the 4th person was not able to connect to all the files and was left in an undesirable state because FM was asking for the path of the file to open and the user had no idea.

 

We just purchased Server 5.5, and were wondering what the limitations were here, with respect to open files, and connected guests. The documentation states that the Server can host 125 files, 50 Files per guest and 250 guests. How can I figure out what combination of uses to files I can support?

 

I contacted FM Pro support, and was told different information. I was told that server can host 150 files, 250 guests which is independent of the number of files, but no mention on the number of files per client. Is there any formula to figure this out?

From a TechInfo note, the formula for Server 3.0 (which I don't think has changed) is:

 

FileMaker Pro Server 3.x:

The number of IDs is huge: 3 * maxusers * MIN(50, maxfiles), where maxusers and maxfiles are the values specified in the Preferences for maximum guests and maximum open files. If 100 and 100 are specified, the number of IDs is 15,000, since the MIN(50...) comes into play. The MIN is there because any one guest can only open up to 50 files. So with FMP Server 3.0, there should be no problem with 100 guests all opening 50 hosted files. It is theoretically possible that if all guests performed some big operation all at the same time, the Server could run out of IDs, but this is probably impossible in real life.

Just increase the logic to a maximum of 125 hosted files.Any guest can still only open 50 files.

I don't think that I have even heard about IDS. I can imagine that FM tracks the number of open files and users but I have not seen it. Where can I find out more about this?

 

Does this same formula apply to FMPro used as a host?

Well. we are actually talking about sockets.

So in FM Peer to Peer Scenario( when is FM hosting files instead of FM server), there is an trade-off between users and guest.

Initialy FM has 254 sockets available take 7 that retains host and you finish with 247 sockets for use.

So the formula for consumed socket would be

Num of files * Num of users * 2 <= 247

In other words:

1 guest could use 50 files (max for FM client

2 guest also 50

3 guest 41

ecc

12 guest could use 10 files

24 guestcould use 5 files.

 

If you use the FM server than max is 250 guests with 125 files open ( in this case you'll need a lot of RAM!!!!)

Ok, so this answers a question I had about FM Pro hosting files, do you have the number of sockets for Server? I just want to make sure that I know what my limit is for future expansion.

 

Thanx

As I said up to 250 users serving 125 files, but if you reach this limit than you'll have to have an hell of computer for serving them concurrently,

So the num of available wsockets will be 2*250*50 (since clients can not open more than 50 files at the same time)
