The relevant error is;

java.lang.ClassNotFoundException: com.appiancorp.rdbms.datasource.BusinessDataSourceValidator

Are you sure /data/appian/ear is 7.11? Looks like this is 16.1 or at least someone copied files from 16.1 into this installation.

Based on the error I can clearly confirm that /data/appian/ear/suite.ear/resources/appian_log4j.properties in your environment has this line:

log4j.logger.com.appiancorp.rdbms.datasource.BusinessDataSourceValidator=INFO

which is for 16.1 that's why JBoss is not starting. It says your appian_log4j.properties is referencing a class that does not exist in this environment.
