No problem. Note that I am using IBO components (there is no IBO session component however).


procedure TProcessing.Execute;
begin
if (ClientSesion = Nil) then begin
ClientSesion := TIB_Session.Create(Nil);
ClientSesion.UseCursor := False;

IBODataBase := TIBODatabase.Create(ClientSesion);
IBODataBase.Path := Owner.DataBasefullPath;
IBODataBase.Password := WS_DB_PASSWORD;
IBODataBase.Username := WS_DB_USERNAME;
IBODataBase.Protocol := cpTCP_IP;
IBODataBase.PageSize := WS_DB_PAGESIZE;
IBODataBase.IB_Session := ClientSesion;
IBODataBase.SQLDialect := 3;
IBODataBase.Connected := True;


IncrementTable := TIBOTable.Create(ClientSesion); //Used to get unique IDs
IncrementTable.IB_Connection := IBODataBase;
IncrementTable.TableName := 'Increment';
IncrementTable.OpenIfClosed;

UpdateQuery := TIBOQuery.Create(ClientSession);
UpdateQuery.IB_Connection := IBODataBase;
end;

while (Terminated = False) do begin
.....
end;

UpdateQuery.Free;

IncrementTable.Close;
IncrementTable.Free;

IBODataBase.Connected := False;
IBODataBase.Free;

ClientSesion.Free;
end;

Session is TIB_Session ? Can you post a little sample ?

Are you setting the connection path using the path parameter or the DatabaseName parameter? I had a similar problem when using databasename, changing it to path helped.

Create a Session for each thread, .Create(Nil)
then create a connection .create(Session) also assign the Ib_Session property. Do the same for all your Table an Query objects.

Create your session & connection in the execute part of the thread. Free it at the end of the execute.

This structure fixed all my problems. Hope this is clear enough :)

I am converting a demo project of borland (see borland\Delphi7\demos\db\bkQuery) I
converted TQuery with IBOQuery, TDatabase with IB_Connection, IB_Transaction,
TSession with IB_Session).

Server = FB 1.5.1, Connection = Local

My problem is when I click quickly on button execute it suspend and I must reset, all is ok if I wait previous query has terminated.

It is only a simple query to Database.

I tried demo thread project in IBO4\Samples\Threads and It has the same problem. Why ? Is there a sample of Threads works fine.

Thank You

Please describe
a) how your application is connecting to the database (Server, Path, protocol)
b) what is being done inside the threads
