Database reference

Use this information to understand the structure of the Network Manager process databases and of the NCIM topology database.

DbLoginSchema database
The DbLoginSchema database defines identifiers and login connections to all of the databases used in Network Manager.
Process databases
These OQL databases are used by all the Network Manager processes, with the exception of the discovery process, ncp_disco, and its subprocesses. The discovery databases are presented separately because there are a large number of discovery databases.
Discovery databases
There are various specialized databases that are used by ncp_disco, the component that discovers network device existence and connectivity, and by ncp_model, the component that manages, stores, and distributes the discovered network topology.
Event enrichment databases
Use this information to understand the structure of databases used for event enrichment and for the Event Gateway plug-ins.
Polling databases
Use this information to understand the structure of databases used for polling.
NCIM topology database
The Network Connectivity and Inventory Model (NCIM) topology database is a relational database that Network Manager uses to consolidate topology data about the physical and logical composition of devices, layer 1, layer 2, and 3 connectivity, routing protocols and network technologies such as OSPF, BGP and MPLS Layer 3 VPNs.
