Hello,
I am using Sever Administration Utility (DBISAM Database Server) where I created 2 databases, on the other hand i created a vb.net application
using Visual Studio 2005. I am opening 2 connections to the 2 DBISAM databases and one to the SQl Server 2005, total of 3 connections.
SOmetimes I am getting a prorol error!
So is it possible that the DBISAM server has a limited number of connections?
Thank you

What is the exact error message that you're seeing ?  There aren't any
native DBISAM error messages that have the word "protocol" in them, so it
must either be an OS error message or an error message from somewhere else.

Hello Tim,

The Exact message error that I am getting is as follows:

"Unhandled exception has occured in your application, if you click continue the application will ignore this error and attempt to continue. if you
click quit, the application wil close immediately "
then this statment is folloed by "Protocol Error"

I sit possible from the operating System?

Thank you

The problems is the exception (protocol error message is likely a result of
the exception leaving the app in unknown state). You need to find out what
throws that first, why and fix it.
If it happens every time then just use a debugger and step thru your code
where the problem occurrs.

Are you getting a stack trace at all from the VB.NET application ?  If not,
then you'll have to run the application in the debugger and see what the
actual error is and where it's coming from.  Then we can proceed from there
to finding a solution.

Hello,

I used the debugger to debug my VB.net application and I am getting the at the 3rd line where I am trying to open a connection to the dbisam
database in the DBISAM Server Utility:

Constants.sqlcon.Open()
 Constants.dbisamcon.Open()
 Constants.dbisamcon1.Open()

Thank you.

Unfortunately, that doesn't really help much.  Was there a stack trace that
you could see ?  That is really what I need to know.

Please do not post attachments in this newsgroup.  Instead, post them in the
Binaries newsgroup here:

Unfortunately, that stack trace doesn't tell me much.  Does this issue
happen on different PCs, or only on a particular PC ?

Hello Tim,

Yesterday, I realized that  the "Server Administration Utility DBISAM Database Server" as shown in the attched screenshot can only afford 5
connections to the dedicated server. In my VB.Net application each user has to open 2 connections to 2 different databases, that's why I was
getting the protocol error on the 2nd connection. I tried to change the "Max # of connections" but it seems it is not an editable parameter. So is
there a way to increase the number of connections? since we are around 100 employees so we need a minimun of 200 connections.
Please could you advise if there is a way to increase the number of connections and how?

Thank you in advance and looking to hear from you soon.
