We have a DB with replica’s on 3 servers. We want to force people to use Server A so I wrote some Database Script in the PostOpen event. Basically the script checks to see if the database the user is trying to open is the one on Server A. If so, then open it. If not then see if Server A DB can be opened and if it can then open the database on server A and close the database the user tried to access, let’s say Server B. In this case, the script is running on Server B.
This works great if the Client is 6.0.3, when we try openning the db on ServerB it opens the DB on Server A and closes the db on server B.
When we try it on a 7.0.2 Client. It Starts to run the Script and the Status bar says “Script is busy” and then it crashes the Notes Client. If we try to open the DB on server A it opens with no problem, only when we try to open it on server B and it redirects it to server A.
The code was developed on 6.0.3 Designer
The servers are 6.0.2 CF1
Here is my code:
Dim thisServer As String
Dim thisDbPath As String
Dim prodServerAName As String
Dim prodServerBName As String
Dim drServerName As String
Sub Postopen(Source As Notesuidatabase)
'01/05/2007 (mdz) this script checks the current server and if it is “DR Server” then it will attempt to open the
'production database on “Server A”. If open is successful then it redirects the user to the production replica
'and closes the source database and also removes the icon on the desktop for the offending database.
removeIcon = False 'this will flag to remove the Icon being used if set to true
