new rule versions not appearing on other nodes



After upgrading Pega PRPC from version 7.1.8 to 7.1.9, every time we deploy new rules in the QA, UAT and Prod environments, we need to restart Pega in order to be able to see and use the new version of such rules.

Error Messages

No error messages are present in the log files during the deploy.

Steps to Reproduce

- Deploy a RAP from Node 1;
- Access the application on Node 2, 3 or 4;
- the old version of the application is presented, instead of the new one just deployed.

Root Cause

The system pulse was changed to default to cluster in 7.1.9. The system pulse agent was not running on all the nodes in the environment.


The solution is to add the following configuration setting <env name=”initialization/pulse/transport” value=”cluster” /> to ensure that that all the configuration is changed from database to cluster and reboot the whole cluster to make sure that cluster is using the default protocol.
