and loaded on the platform when the server successfully establishes a connec-
tion with the underlying database. The Oracle SOA Suite 11g infrastructure re-
gisters a database-backed MDS repository with the domain where composites
can commit their customizations. This is usually done when the domain is exten-
ded with SOA Suite. However, there may be situations where you will need to
register a new repository with the domain. Consider an example where there is
a need for separate metadata repositories to store data of two different compos-
ites, catering to different business functions, but deployed to a common domain.
Achieving this is possible using the Oracle Enterprise Manager Fusion Middle-
ware Control console or WebLogic Scripting Tool (WLST) scripts that allow re-
gistering new repositories post domain creation. The following figure shows the
various components of the MDS runtime engine and how they interact to provide
the implementation of metadata storage:
In this chapter, we cover various areas related to MDS management that in-
clude:
•
Registering a database-based MDS repository
•
Managing metadata repository partitions
•
Purging metadata version history

Registering a database-based MDS
repository
Upon installing Oracle SOA Suite 11g, the MDS is typically registered with your
SOA domain, but there are cases when it may not have been registered or cases
