4. What databases are part of every solution?
BizTalk Server Management database, MessageBox databases, Tracking database,
and SSO database are four databases which are used by BizTalk server runtime
operations. It is the component that encapsulates and abs07acts the database
component and is the interface used by BizTalk Server to interact with the
MessageBox. The Message Agent is a Component Object Model (COM) component that
provides interfaces for publishing messages, subscribing to messages,
re07ieving messages, and so on. This interface is the only mechanism used by
other BizTalk Server components, including the adapter framework and
orches07ations, to interact with the MessageBox.
5. Which service looks after known issues in the
database?
Monitor BizTalk Server, this job scans the BizTalkMgmtDb, BizTalkMsgBoxDb and
BizTalkDTADb database for any known issues, including orphaned instances.
6. How would you define database role in context
to BizTalk?
The database is used to store the data about the Message and other data
required for processing it, along with the help of SQL Server Agent Jobs.

MessageBox_Message_ManageRefCountLog_BizTalkMsgBoxDb is the job which runs
continuously in spite of scheduled to run once per minute.
8. Messages without subscribers are removed, how?
MessageBox_Message_ManageRefCountLog_BizTalkMsgBoxDb determines when a message
is no longer referenced by any subscriber. When no subscriber found it starts
MessageBox_Message_Cleanup_BizTalkMsgBoxDb which removes the unused message.
9. Does implementing BAM require more database?
Yes. BAM Analysis, BAM Archive, BAMAlertsApplication, BAMAlertsNSMain, BAM
Primary Import database and BAM Star Schema can be used to implement BAM solution.
10. Which database stores the configuration
information for receive locations?
Single Sign-On database (SSODb) securely stores the configuration information
for receive locations, other known secret information is stored in
the BizTalkMgmtDb.

BRE?
