This chapter contains information on the requirements for creating and configuring the Oracle Communications Offline Mediation Controller Nortel DMS Operational Metrics (OM) node chain. For a diagram of the node chain, see "Architecture".
To configure the node chain for OM collection with OM file distribution, you must create and configure an OM CC and an OM DC. You can connect the nodes with any kind of routing and it will not impact the functionality of the nodes. The mechanism of communication for the nodes is the directory in which they store and retrieve files. You can configure this mechanism in the node configuration windows.
If you want the DC to output files, you must select the Use FTP checkbox and enter the correct FTP parameters for the remote device.
You can provision a backup OM CC as a means to recover from a polling failure rather than wait for the next scheduled poll. For example, if the log file of the primary OM CC indicates a polling failure, you can manually configure the backup OM CC to have a short polling interval, such as 5 minutes, for a specific switch. The backup OM CC will collect the files the primary OM CC failed to capture. After the files have been transferred successfully, you can stop the backup CC. This backup method can be used to manually initiate polls the switches instead of waiting a longer period for the primary OM CC to attempt to re-establish the connection.
