Hi, all!

I'm new in multi-tier database development, but I have a solid backgound in
desktop database dev.

I tried to develop a database server using MIDAS, and it works pretty fine.
I can send query to the server, and it returns me the dataset.

The trouble is that when I have more than seven or eight clients
applications connected to the server, and that each one has an open dataset
tied to the database, the server crashes and return a :
TDBEgineError : Insufficient memory for this operation.

I assume that I'm opening to much connections to the database, but I don't
know how to solve the problem. What am I doing wrong?

My database is of Paradox type. My server uses the Apartment threaded model.
There's a TSession, TProvider and TQuery on my RemoteDataModule.

If someone could help me, and/or supply some URLs where I could learn more
about MIDAS with BCB 5.

Hi, Martin!

You also need to figure out whether or not you are actually running out
of memory or connections. Also, check the BDE administrator on the
machine in question and see if there are any parameters that may need to
be made larger.
