Spectrum OneClick Connection Log show "SPC-OCA-10360: Connection lost." error message.

The Spectrum OneClick Connection Log is showing the following error:



Release : Any

Component : Spectrum OneClick


As the message states, OneClick (OC) lost communication with the landscape. Possible root causes:

- Is the SpectroSERVER (SS) process running on that system. If not:

Did the SS crash? If so, restore to a previously saved database and start as normal. Then trouble shoot why the SS cashed.

If the SS did not crash, start the SS normally.

- A network issue between the OC and the SS system

- A firewall preventing communication between the SS and OC systems. Please reference the "Communication Across Firewalls" section of the documentation concerning the required ports for OC and SS communication.

- Ensure hostname resolution between the SS and OC AND between the OC and SS systems. Hostname resolution should be good both ways.

- Ensure the OC system hostname or ip address is in the $SPECROOT/.hostrc file on the SS system

- Check the $SPECROOT/tomcat/webapps/spectrum/META-INF/context.xml file and ensure the "locServerName" parameter is pointing to the correct Main Location Server (MLS) system and the "adminUserName" parameter is a valid Spectrum user model in the SS database. 

- Are both the SS and OC systems running the same Spectrum version? You can check the $SPECROOT/Install-Tools/.history file on both systems to verify.
