Current Revision posted to Appian Knowledge Base by Parmida Borhani on 10/16/2019 12:46:14 AM

Symptoms

When attempting to start data server in Appian versions 18.1 or later, the data server fails to start with the following error observed in the watchdog.log:

{"level":"ERROR","time":"YYYY-MM-DDTHH:MM:SS.mmmZ","logger":"watchdog","caller":"Watchdog.java:652","thread":"ForkJoinPool.commonPool-worker-2","msg":"Failed to start RTS-0 engine (port=port)"}
com.appian.data.server.UnrecoverableError: Could not establish WebSocket connection with hostname:port. The target q process exited abnormally. Check for earlier errors (e.g. license or startup errors).

Additionally, the rts-engine.log reports:

'YYYY.MM.DDTHH:MM:SS.mmm host

Cause

The output from the rts-engine.log is seen when the license issued does not match the hostname of the server it is deployed on.

Action

The data server requires a valid k4.lic license file. Generate the q output and compare the hostname from the output to the hostname of the server for which license was requested. If the hostnames do not match, request and install a new license.

Affected Versions

This article applies to Appian 18.1 and later.

Generate the q output. Reference the given document for generating the q output.
Compare the output for hostname in the output of q command above and hostname of the server for which license was requested.
In case they don't match, request a new copy of license and deploy as per the documentation.
