Since the upgrade from version 6.9.0 to cumulative patch version 6.9.1 on NES, the service Nolio Release Automation Server Watchdog failed to start.
CA Release Automation Execution Server - version 6.9.1
There is a nolio_server_watchdog.vmoptions file in the NES's parent folder <RA_HOME> (e.g.: C:\Program Files\CA\ReleaseAutomationServer\).
Add the following line in the end:
-classpath ./watchdog/watchdogsvc-6.9.0.jar
After this line is added start the watch dog service.
The proper fix which will be delivered in the further releases.
