Hi,

We are converting a 2-tier project that worked flawless with IBO to 3-
tier. The options at the moment are MIDAS and DbOvernet. For both I have
a basic framework ready.

Has anybody used IBO + Firebird + MIDAS before??
The reason I ask is because I can get the middleware, we use
socketserver, to lock up consistently. This happens when I access the
middleware with more than one client. My guess is that it has something
to do with threading.
DbOvernet by default doesn't thread and here I don't see any lockups.

I am using a single TDataModule that contains
IB_Connection
IB_Transaction
Session Management

Each TRemoteDataModule uses
Multiple Instance
Apartment

I haven't tried
Single Instance
Single

yet

Furthermore I am still using IBO3 but thinking about going to IBO4

Any suggestions and past experiences are welcome

regards
Paul Sjoerdsma
