If you run a central main and a central backup server together with a number of MNC server, all MNC servers needs to be configured to send there events to both central servers.
In this case it is also possible to store copies of all events (duplicates) in a local EventDB on the MNC server. This may be useful, if there is also a local access to the MNC system configured or if you want to use the legacy Java client.
| setting | only central | with local copy |
|---|---|---|
| local.edb | no |
yes |
| duplicate.edb | no |
yes |
| primary destination | [main-server-addr] |
[server-addr] |
| secondary destination | [backup-server-addr] |
[backup-server-addr] |
[main-server-addr] is the IP address or hostname of the main central EventDB server. If you specify an hostname make sure the name resolution is configured and works reliably. Remember that the DNS request may slow down operation.
[backup-server-addr] is the IP address or hostname of the backup central EventDB server. If you specify an hostname make sure the name resolution is configured and works reliably. Remember that the DNS request may slow down operation.
[server-addr] should not be localhost or 127.0.0.x because duplicated.edb implies that already.
