Clustering Aurea List Manager
Multiple Aurea List Manager instances (or nodes) may be clustered together using a single database.
The benefits of a clustered Aurea List Manager environment are:
- True load distribution: Any node can perform any task, including sending mail, receiving incoming mail, accepting tracking events, or performing scheduled tasks.
- Redundancy: If one node goes down for any reason, others pick up the pending task or tasks.
- No single point-of-failure: No single critical Aurea List Manager system must be working for the cluster to function (other than the database server).
- Improved bounce processing speed: Processing and saving bounced mail in the database is faster.
Important Clustering Notes
- Message recipients may receive duplicate messages in a cluster if the same message is posted to multiple lists and/or segments. Duplicate messages are received even if the list(s) are set, so members do not receive crossposted duplicates.
- To send the same message to multiple lists and segments, send to each list and segment separately, purging out recipients of earlier messages on the Mailings > New Mailing > Recipients tab.
- Recency limits may also be ignored if a second mailing is approved before recipient list processing for the first has been completed.
- You can not select which node a message is sent from. Aurea List Manager distributes messages across the cluster automatically.
