You can install more than one connector for failover purposes. If the primary connector becomes unavailable, the secondary connector acts as a backup to send and receive events. However, for the backup connector to receive alert updates from Netcool, you need a separate instance of the SNMP Gateway that can forward updates to the backup connector.
To configure a two-connector failover system:
Install two separate connectors on two independent computers. For information, see Installing the Connector
Ensure that both connectors use the same AppManager repository. Using two different AppManager repositories might result in the loss of event information on events with the same event ID that came from different AppManager repositories.
Ensure that both connectors use the same connector database.
Configure each connector to have the same filtering and polling values. These values are maintained on each computer where you have installed the connector, along with the rules and properties files.
NOTE:Repeat the process if there are more than two connectors.
One connector will be designated as the primary one where you can configure the following parameters:
AM Event ID field (if used)
AM Event Source field (if used)
Restart Period
Netcool Save Details
A secondary connector does not allow you to change these values.
