Switching to failover configuration with NCIM topology database high availability

You can modify an existing failover architecture to include NCIM topology database high availability.

About this task

Note: In previous Network Manager releases, users could include an NCIM topology database failover configuration by using NCIM replication (also referred to as NCIM topology database replication). The NCIM replication feature has been replaced by the high availability feature that is provided by the supported database:
  • If you have a Db2® database, you can use the High Availability Disaster Recovery (HADR) feature to set up failover for NCIM.
  • If you have an Oracle database, you can use the Real Application Clusters (RAC) feature to set up failover for NCIM.
To configure NCIM topology database high availability:

Procedure

  1. Set up NCIM topology database high availability by using the high availability feature that is provided by the supported database.

    Db2:If you have a Db2 database, follow the procedures described in the Db2 documentation to configure a failover configuration for the NCIM topology database using the HADR feature. See Related information later for links to your Db2 Information Center.

    Oracle:If you have a Oracle database, follow the procedures described in the Oracle documentation to set up the Real Application Clusters (RAC) high availability environment. Using Oracle RAC, you can create a high availability setup for your NCIM topology database. For information on how to install and configure Oracle RAC, see Related information later for a link to the Oracle documentation.

  2. Configure Network Manager to work with the supported database as described in Configuring Network Manager to work with Db2 HADR or Oracle RAC.
