Steps to Reproduce



Log in to a fresh Pega 7.1.7 installation and attempt to use links and buttons in the Designer Studio.

Root Cause



The root cause of this problem is defect or misconfiguration in the operating environment.
The errors in the PegaRULES logs indicate that Initialization of the Search sub-system and hazelcast clustering failed.
A socket issue during hazelcast initialization caused the PRPC node on port 5702 to refuse the connection.


Resolution



Perform the following local-change. 
Add the following entries in the prconfig.xml file and restart the JVM:


<env name="cluster/hazelcast/multicast/enabled" value="true" />
<env name="identification/cluster/protocol" value="hazelcast" />

For more information about these environment settings for hazelcast clustering, see SA-9502, HazelcastException after upgrading from 7.1.6 to 7.1.7.
