Pega 7.3 Cassandra Setup - Configuring D-Nodes without UI
Greetings,
So I'm in the process of setting up a 7.3 cluster which will contain 3 separate nodes to be allocated for Cassandra. We will be using the Internal Cassandra integration to achieve this.
I understand that once activated via the UI, Cassandra as a process starts on the D-Nodes and goes through a bootstrap process whereby it reads a cassandra.yaml file and combines inputs from prconfig.xml to create the final cassandra.yaml which gets bootstrapped.
But as an Ops person, I need to know how I can configure this without using the UI in order to create a configuration deployment process that is repeatable.
How can I achieve activation and allocation of the D-Nodes via prconfig.xml (and/or other config files) alone? If for whatever reason this is not possible, is there an alternative way I can create a repeatable process?

Hi Christopher,
Kindly go through the below doc to know how you can configure D-Nodes manually.
https://pdn.pega.com/documents/decision-strategy-manager-d-node-operations-guide-718
We can use the below configurations in prconfig.xml to setup the nodes:
<env name="cluster/hazelcast/members" value="10.88.29.85,10.88.29.99" /> -- list of values, IP
<env name="cluster/hazelcast/members" value="10.88.29.85-99" /> -- range of values (.85-.99)
Please let me know if this helps.
Regards
Vikash
