Using Cumulus Catalogs as Mirroring Target Databases
Cumulus catalogs can also serve as mirroring target databases. This requires a second Cumulus Server installation. Then one Cumulus catalog can be mirrored to another Cumulus catalog of the other Cumulus Server installation. This offers failover functionality and load balancing. A target Cumulus catalog at the secondary Cumulus Server is set to read only. With read-only applications (e.g. Web Publisher Pro) it can be used as a read-only replica and take load from the primary Cumulus Server. Note that Cumulus Triggers only work in the original catalog.
NOTE: Mirroring Cumulus 6 Catalogs If you mirror a Cumulus 6 catalog, the target catalog will always be a Cumulus 7 catalog.
When using Cumulus as target database system, the following data are required to define the database serving as mirror:
• Server – IP address of the computer hosting the Cumulus Server
• User – Login name of the Cumulus Administrator of the Cumulus Server used as mirror.
• Password – Password of the Cumulus Administrator of the Cumulus Server used as mirror.
• Database Path – Path of the Cumulus catalog file
NOTE: You can either enter the path of an existing catalog or have a new one created by entering its path.
