[OO Tip] Cluster Clients are not shown in the Terracotta Developer Console

Problem:

Using the Terracotta Developer Console (%ICONCLUDE_HOME%/Clustering/terracotta/bin/dev.bat) to monitor the Operations Orchestration (OO) Cluster will not show any Connected Clients, even though the OO Cluster is working as expected.

 

Resolution:

 

The reason why Connected Clients shows zero in the Terracotta Developer Console is that when the Cluster was started the wrapper.java.additional.x parameter that is referencing "-Xbootclasspath/p:"%ICONCLUDE_HOME%/Clustering/terracotta/dso-boot-hotspot_win32_160_18.jar" was not loaded.

In order to fix this issue the following must be done:

1. Go to and edit %ICONCLUDE_HOME%/Central/conf/wrapper.conf on the Cluster nodes

2. Find the -Xbootclasspath/p:"%ICONCLUDE_HOME%/Clustering/terracotta/dso-boot-hotspot_win32_160_18.jar" reference and create a new wrapper.java.additional.x parameter at the end of the wrapper.conf

wrapper.java.additional.x=-Xbootclasspath/p:"%ICONCLUDE_HOME%/Clustering/terracotta/dso-boot-hotspot_win32_160_18.jar

Where x is the number of previous wrapper.java.additional statements in the file 1.

3. Restart the OO Cluster
