Bonjour a tous ,
SVP est il possible d’installer Interbase 7.5 server sur une machine qui contient deja interbase 6.5 ?
le probleme est : j’ai besoin de modifier le mot de passe du SYSDBA , et je ne veut pas desinstaller interbase 6.5 car il est utilisé par une autre application.
Merci a tous.

Bonjour a tous ,
je ponse que j'ai trouvé la reponse a ma question :

If you don’t have an InterBase server installed on your computer so far, and this will be the only installation on the target computer please select Multi instances "NO".

If you have InterBase (4.x, 5.x, 6.x, 7.x) already installed on your computer and still want to use it, you have the possibility to configure the multi instance installations. For this you select the option Multi Instance "Yes", enter a free port number and give the instance a new name. Earlier versions of InterBase and single instance installations use the standard port number 3050 and the instance name gds_db. For a multi instance installation you have to give new values.

Example:

You have installed an InterBase 6.5 server on your machine. Additional to this you want to run InterBase 7.5 in parallel. Choose the Option Multi-Instance to „Yes“, Instance Name for example. „gds_75“ and the Port 3075. This has the advantage that existing applications will still run with InterBase Server 6.5.
