19.5.2 Replication of configuration files
NNMi running in an HA environment uses file replication to maintain copies of the NNMi configuration files on all NNMi nodes in the HA cluster. By default, the NNMi command nnmdatareplicator.ovpl manages file replication. This command monitors the updating of configuration files located on the local disk. When a configuration file is updated, the command copies it to the shared disk. In the event of a failover, the command copies the most recent configuration files from the shared disk to the target node. After that, NNMi is started.
The above update verification and copying of the configuration files are a part of the NNMi monitoring process that is run periodically from the HA cluster. Therefore, if node switchover occurs after configuration files have been changed but before they were copied, the changes are not applied. In such a case, you must change the configuration again.
In the nnmdatareplicator.conf file, specify the NNMi folders and files to be included in data replication.
For details about the data replication process, see the nnm-ha manpage.
