Products

Issue/Introduction

Hub and robot were successfully updated to 23.4.5 on a secondary but core java probes fail to start after the update

Example

nas.log

Controller: Probe 'alarm_enrichment' FAILED to start (command = ../../../..//bin/java.exe -Xms1024m -Xmx2048m -Djava.library.path="../../../../lib" -Dfile.encoding=UTF-8 -jar ../lib/alarm_enrichment.jar) error = (2) The system cannot find the file specified.  

baseline_engine.log

Controller: Probe 'baseline_engine' FAILED to start (command = ../../..//bin/java.exe -Dfile.encoding=UTF-8 -Dpds.encoding.charset=UTF-8 -XX:+UseG1GC -Xmx1024m -Xms64m -Dlog4j.configurationFile=log4j2.xml -DNIMBUS_HEARTBEAT_INTERVAL_SECONDS=5 -Djava.library.path="../../../lib" -jar lib/BaselineEngine-23.4.5.jar) error = (2) The system cannot find the file specified.

Environment

DX UIM 23.4 CU5

Cause

Core java probes released with CU5 require Java 21 as a dependency.

Resolution

1. Deploy java_jre21 to the secondary hub

2. Select each probe and right-click and select Security->Validate then Yes to all.
