Thanks

@Naveen: The above error means that The user that ran the start-suite.bat|sh command does not have read and write permissions over one or more of the .kdb files for the engine(s). To resolve this follow the below steps:
1. Stop Jboss application server.
2. Stop search-server.
3. Stop Appian Engines.
4. Now run cmd as an administrator and run start-suite.bat |sh command.
5. Verify the engine status and once all engines are in OKAY state, follow next steps.
6. Rename suite.ear.failed to suite.ear.dodeploy at location <APPIAN_HOME>\\ear.
7. Delete the *.ds.xml.failed or *.ds.xml.undeployed inside JBOSS deployment folder.
8. Start the search-sever and jboss.

Let me know if it works or you face any other issues.

Nilesh is accurate with his root cause.

I would like to add just one more thing to this since it looks like you are using a Linux based OS.

I would do the following:
1) Stop App-server
2) Stop Search-server
3) Stop Appian Engines
***4) chown -R appian:appian /hosting/appian (assuming that the user you created for installing / running the software is appian)
5) Start Appian Engines (as the appian user)
6) Start Search-server (as the appian user)
7) Start App-server (as the appian user)

Hope this helps!

Thank you Nilesh & Alok. Appreciate your help.
