Built-In Administration
ICM software maintains a database on each side of the Central Controller and a
local database on each Distributor Admin Workstation. Each database consists of
a group of interrelated tables. As you add or update data in the database, you must
ensure that logical relationships are maintained. For example, if you delete a trunk
group, you must not leave trunks in the database that reference that trunk group.
If you do, the integrity of the database is broken.
Configuration Manager prevents you from making certain changes that disrupt the
integrity of the data in the database. However, it cannot prevent all such changes.
Usually, if data integrity in the local database is temporarily disrupted, no major
problems occur. However, integrity problems in the central ICM database could
cause errors in system processing.
Note To protect the integrity of the ICM databases, do not use third-party tools to
modify them. These tools do not protect against disruptions of database
integrity. (You may use third-party tools to view ICM data.)
When your ICM support provider installs the ICM system, they perform integrity
checks to make sure that the database is configured correctly. After that, the
integrity of the central database is maintained by the ICM software. You do not
need to manually check the integrity of the ICM central database. If you ever have
a problem with data integrity in the central database, the problem is most likely a
software problem that needs to be addressed by your ICM support provider.
Caution Any manual integrity checks of the central database must involve your ICM
support provider. Do not run the DBCC CHECKDB procedure on the central
database while the ICM system is running. This procedure will stop the
Logger. Similarly, do not run the UPDATE STATISTICS procedure while the
ICM system is running. The Recovery process runs UPDATE STATISTICS
automatically.
