Oracle XE not running on CentOS machine

Question

Hi,
I have installed Oracle-XE on a CentOS machine few months back and it was running fine since then, however for the past 2 days it is not running after I rebooted the machine.
When I checked the status of /etc/init.d/oracle-xe the output was

This is the Oracle Apex Listener forum.
Please post on {forum:id=251}.
Hint: You perhaps need to START your DB.
