May of some help.

Not till IBO version 4.3.Aa could you set IBODataBase.IB_Session :=
IBOSession;
And you have to include that statement, else IBODataBase will use an
internal Session.

To be safe add

IBOSession.DefaultConnection := IBODataBase;

IBOTransaction.IB_Connection := IBODataBase;

> I am testing a converted Delphi 5 Paradox app (currently using the
TIBOxxx components) and getting some strange behaviour which I am having
trouble tracking down. The app is an Interactive Voice Response system which
manages up to 8 telephone lines to make reservations at sports facilities. I
am using Dialogic D4PCI telephone interface cards and third party software
which is the API interface to the Dialogic drivers. This 3rd party software
is multi-thread. My application is not multi thread but is re-entrant with
all database access forced to be single thread via a mutex. Not elegant, but
it worked fine with the Paradox files on a file server. The converted app
using TIBOxxx also forces access to the app gdb to be single thread also,
with all queries having a short life span: open, do your thing and close
within the confines of the mutex.

and tables. In the IB version I have employed a TIBOSession component and
set the session property of the TIBODatabase and all table and query
components to it. I assume this will isolate the database access from any
VCL processing. The app dynamically creates 'n' MDI child windows in an MDI
parent form. Each child just contains a memo component which is used to
display call progress information for each call. With the same app in
different environments I get different results such as:

> XPPro(Pentium 4), my app, IB and IBO - call progress display disappears
and some tel lines freeze forcing a task manager intervention to shut down

tests but way better than XPPro or WIn2000)

different machines and still can't figure out where the problem might be. I
am guessing that this is a session problem??. ANY guidance or tips would be
hugely appreciated.
