Appian not started with SafeRetryException

Hi!
I installed Appian locally for demo purposes, got a temporary license, but JBoss failed to start Appian with the following exception. I can’t get any way to fix it from the exception itself, can you advise what can be wrong?
Caused by: com.appiancorp.kougar.driver.exceptions.SafeRetryException: Unable to acquire a Read connection. Safe to retry.

Restart the jboss,by doing following.
1.Check all engines are in OKAY status
2.change the suite.ear.failed to suite.ear.dodeploy
3.delete the appian-ds.xml.undeployed file
4.delete the jboss temp directory
5.delete the jboss data directory.

I did items 2-4, then I had to redeploy with <APPIAN_HOME>\\_admin\\_scripts\\configure\\configure.bat
with the same result.

The checkengine.bat (windows) or checkengine.sh (*nix) provides you with the status of your engines.

Hi,
The configurations deployment to be done once (redeployment is not requiered).
Please verify the all configurations are correct before starting the engines and jboss.(custom.properties , appian-ds.xml , standalone.xml and com folder). And also please verify the COOKIE configurations are deleted in web.xml or not.

checkengine failed with all services not responding. Appian doesn't start so no services available.

Hi ramanjaneyulut, deployment is done into jboss data directory. When I removed it, no deployment available, had to redeploy.
What configuration option can cause this exception? Appian validation passed OK.

Hi Eduardo,
The first one is about miscommunication between two machines which is not my case.
Second one is about invalid license which is not my case either.
Search for "SafeRetryException" returns nothing. :(
