Pega environment Issue - Multi node
Hello,
We are facing an issue with Dev environment, which has two nodes. Issue is - whenever a rule is modified in node1 and checked in. The same changes are not reflected in node2.
If anyone of you, faced the same issue. Can you please let us know the steps to resolve it.
Thanks, - S Ch Avinash

Hello Avinash,
Are you guys pointing the same DB to other nodes? This should work, if you made any changes in node 1 it should effect in node 2 too.

Hi Naveen,
Yes, we are pointing both the nodes to same DB. Still there is this issue.

It can be a problem with hazelcast protocol. Do you have Load Balancer behind these two servers? Could you please check table called pegadata.pr_sys_statusnodes. You should have there a list of nodes that working in cluster. If you do not see there all nodes it means that there is miss-configuration.

Till now, I was able to find this issue is happening for below rule types,
decision table, activities and data transforms.
I suspect, there are no specific rules. It might be happening for all rules.
