Use a database on a shared network

Spread the love

(*
If you use a database (tables) on a shared network,
you can enhance efficiency by setting a number of properties
of the TSession component.
The TSession component manages a database session.

First of all, Session.PrivateDir should be assigned to a local directory,
like C:\WINDOWS\TEMP (you can do this in the OnCreate event of your DataModule,
for example).
The PrivateDir will contain the result of a local Query
(which is a table in itself), and a local table is of course much faster
than a table on the network (LAN or otherwise).

Second, Session.NetFileDir should be assigned to the same physical value
for every user, like ‘X:\BORLAND.COM\BDE’ (this also can be done during
initialisation).

procedure TForm1.FormCreate(Sender: TObject);
begin
     session.netfiledir:= 'X:\BORLAND.COM\BDE' ;
end;
