HAZELCAST cluster member IP address
Hi
We have a problem in our implementation(PEGA platform 8.2.2) where AUTO discovery of nodes in HAZELCAST fails. Looking through the HAZELCAST documentation we came across below setting . We are trying to explicitly list the IP address of the nodes which can be routed.
|
Cluster Members |
initialization/cluster/members |
A static list of cluster member IP addresses, separated by commas Disables automatic discovery |
Not Applicable (user defined) |
<IP 1>, <IP 2>, …. |
Can you please help us with the steps to explicitly define members in the cluster with their IP address?
- Can this setting be incorporated under Dynamic system settings? If so will it override what is in the database?
- Is there any other way of adding this setting in a live environment without having to redeploy PRweb.war
Thanks,
Sri.

I'm not 100% sure this particular setting can be set using DSS: you would need to try it on a DEV system ideally. But take a look at this (general) document regarding the relationship between prconfig.xml/DSS
https://community.pega.com/knowledgebase/articles/how-compose-key-prconfig-dynamic-system-setting
Please note DSS values are stored in the DB already - so can you clarify your question 1.
For question 2: You won't be able to do this dynamically on a running node (there is no way of stopping and starting Hazelcast independently of stopping and starting PRPC) - but changing the DSS and restarting the (all) the nodes should be possible - again you would need to try that I think.
Others on this forum may have already tried this and be able to give more specific advice though.
