Administering the NCIM topology database

Network topology information is held in the NCIM database.

About this task

Changing the NCIM access details
If you change the host name, port, password, or database name of the NCIM database, you must complete some configuration tasks to enable Network Manager to connect to the database.
Creating the topology database schemas
You can set up the topology database during installation. If you need to set up a database after installation for an existing Network Manager, then you can do this manually using the scripts provided.
Removing domains from the topology database
When a domain is no longer required, use the domain_drop.pl script to remove it from the NCIM topology database. The entire topology for the domain is removed and any poll policies for that domain. The configuration information for the domain and the topology cache are not affected.
Removing all entities from domains
As an alternative to dropping domains from the NCIM database, you can use an SQL DELETE statement to remove all entities from domains. Unlike dropping domains, if you remove all the entities, the mapping between the entityName and entityID persists.
Removing the topology database
You can remove the topology database if it is no longer required.
