session and database

[AntonioCuomo]

If j have a TABSDATABASE on unimainmodule the component is shared with all session?

 

How have a TBSDATABASE for every session?

 

Example:

 

User1  --->    DB0001.abs

User2 ---->    DB0002.abs

User3 ---->    DB0003.abs

....

 

if j change at connession  the filename for all user the DB is the DB of last user.

 

Is ABsolute Database not compatible?

If you find any solution please post it

My understanding (from the online UniGui documentation) is that the ServerModule exists for all sessions while the MainModule is created separately for each session.

 

So if you put a database connection in MainModule, it will be specific to one user and session.

 

I may be wrong, but I think a database connection in ServerModule is not recommended.

The link a database is on Mainmodule.

 

j tested also with a link on Datamdule.

 

Probabily the absolute not is multi thread?

Hi,

 

You must follow same principle when you use BDE in a multi-threaded app. Basically you must have a separate TABSSession object for each uniGUI session.

 

See here:

Put a TABSSession on MainModule and set AutoSessionName -> True.

Put a TABSDatabase on MainModule and set its SessionName to TABSSession.Session name.

In a normal app all users must share same ABS database file.

Correct!!!

I have put an ABSSession in UniMainModule Form and assigned the Session Name to ABSDatabase.

Now every time UniMainModule is created (= new user) then a new session is created and the database works perfect!

 

**Note you have to put the database inside the isapi dll folder.

UniMainModule.ABSDatabase1.close;
UniMainModule.ABSDatabase1.DatabaseFileName := UniServerModule.FilesFolderPath + 'TestFolder/Novus_Conceptus.abs' ;
UniMainModule.ABSDatabase1.Open;
