Help | Biztalk configuration in 2 machines
|
|
|
| Hi All,
I have carried out Biztalk server installation in 2 different boxes to try
and create a Production like setup.
I have configuration them work in a Biztalk group. When carrying out the
first configuration, I created a group with SSO master as YES. For the
second, I made it join the group with Master SSO option as No.
The configuration information of box A is as follows.
• Master SSO server with the SSO database.
• Master Message box database.
• All the other Biztalk Server databases.
• Default Biztalkserver host : BiztalkServerApplication
• BiztalkServerIsolatedHost
The configuration information on box B is as follows.
• Slave SSO server with no SSO database.
• Slave message box database (scaled out to this box).
• Default Biztalkserver host : BiztalkServerApplication
• BiztalkServerIsolatedHost
• For database settings, it point to box A.
I carried out few simple test scenarios
1) I disabled / stopped the default host in box B but Box A was able to
process any request. - Passed
2) I disabled / stopped the default host in Box A, but Box B was able to
process any request – Passed.
3) I made the master Message box database in Box A OFFLINE, hoping that the
slave in Box B will handle any incoming request. Failed . The default host in
Box A and Box B automatically stopped.
4) I made the slave Message box database in Box B OFFLINE, hoping that the
master in Box A will handle any incoming request. Failed . The default host
in Box A and Box B automatically stopped.
In general, when I take the message box database offline (in either A or B)
(for testing database fault tolerance), the default host instance in A and B
stops automatically and does not process any incoming request.
How to handle this scenario? Please advice. This information is critical for
my project. Many thanks!

| Multi messagebox is not for fault tolerance but for scale out. For fault
tolerance they should cluster the message box on a SQL cluster. Plus in two
message box configuration performance goes down. You need three if you are
looking at the performance. Also, see the BizTalk Server 2004 Performance
Characteristics whitepaper @
http://www.gotdotnet.com/team/wsser...Performance.zip See
the topic Scaling Out SQL Server Test Results on page 22.
