I have installed Appian on my PC and till the command start-suite.bat everything

Link to the post where a practitioner got into a similar case

forum.appian.com/.../e-215548

I would like to suggest few steps to see if it resolves your issue.

1. Stop the Engines.
2. Run the CheckEngine to confirm the status of all the engines reporting as FATAL
3. At this point, make sure you do not have any running processes(in the Windows Task manager) that are Appian related. If there are, please kill the processes manually
4. Start the Engines again.

If some of the engines continue to report FATAL status -
1. Stop the Engines
2. Please go back to the last good KDB files for the problematic engines and rename to make them highest numbered(eg. pd8.kdb to pd12.kdb).
3. Start the Engines

I am attaching the server log file. The FATAL issue status got resolved and status for every instance said 'okay'. Now when I start JBOSS and open my url- hostname.domain:8080/suite, it says 'Web page cannot be displayed'. Please help

serverlogfile.txt

Is the attached server log taken after jboss has been started? Because, the server log shows that there is an error while starting the jboss and that error seems to be related to missing of .dodeloy file in <Appian>/ear folder.

@milid, Your app logs indicate that deployment of Appian EAR did not go through successfully because your Jboss standalone.xml is missing several required configurations. Please make sure to complete all the steps mentioned in the Quick Installation https://forum.appian.com/suite/help/16.2/Quick_Start_Installation_Guide_for_Windows_and_JBoss.html, if this is what you are following for the installation.

@milid, Can you also please also share the root cause of the engine issue and how did it get resolved? It's always good to share the findings and solutions to the benefit of the Forum user community.

@mathanap Yes, the attached server log file has been taken after jboss had been started.

@prosenjitd, I started appian again and just after start-suite.bat , I ran the command checkengine.bat. The status for all instances showed 'OKAY'.

@prosenjitd I have followed the https://forum.appian.com/suite/help/16.2/Quick_Start_Installation_Guide_for_Windows_and_JBoss.html but still when I start JBOSS and open my url- http://hostname.domain:8080/suite, it says 'Web page cannot be displayed'. I am attaching the new server log file after starting appian again.

Once the jboss is started successfully then we would get message in log like 'Started in <yyy>ms. Started <yyy> of <yyy> services'. Based on the type of installation you did, follow the corresponding documentation once again and make sure that all required configurations are done correctly. As pointed by prosenjitd there might be some configurations missing in standalone.xml.
Follow 'ERROR' and its corresponding 'Caused By' in the log to track and debug the jboss error.
