All supported DX NetOps releases
Spectrum tomcat is heavily utilized or doesn't yet recognize that all Landscapes are up again.
To resolve this some users have rebooted the OneClick web server host that is integrated with Portal as a Data Source.
Other users report a simpler OneClick tomcat web server service restart resolved the issue.
To restart tomcat log into the OneClick system as the user that owns the Spectrum install. In an command prompt on the server move to the $SPECROOT/tomcat/bin directory and run"./stopTomcat.sh" to stop tomcat. Then run "./startTomcat.sh" to start tomcat.
The Spectrum data source should now sync successfully after the restart. Allow time for the sync to start and complete as the tomcat restart triggers a full Spectrum data source sync.
