Hi Dojo,
I would like to know if there is any issue/problem when we want to add new DMAs to a system where Cassandra DB is an external cluster. The intention here is create a first DMS with 2 DMAs and a Cassandra cluster, and later on we will add new DMAs. When we add more DMAs with this architecture, do you know if any additional step is needed to connect these new DMAs with the DMS cluster and Cassandra Cluster?
Thanks!
Hi Daniel,
Here’s the procedure I would do to achieve this:
1. Perform the DataMiner SW installation on the new DMA server (link to docs). –> this will install both DataMiner SW as well as a local cassandra database on there.
2. Stop DataMiner SW on the newly installed DMA server.
3. Modify the C:\Skyline DataMiner\db.xml file on this newly installed DMA server so that it matches the db.xml file contents as present on the DMA servers of the production DMS and connected to the central Cassandra cluster.
4. Start DataMiner SW on the newly installed DMA server. –> the new DMA is now connected to the central cassandra cluster instead of the local cassandra node.
5. Stop the locally installed cassandra node on the newly installed DMA server.
6. Initiate the “Add a DMA to a Cluster” procedure as described in our documentation
Hopefully this can help you out!
Thanks for your explanation Jeroen! I’m sure it will be helpful.
Regards!
