Oracle Application Server Won't Start
One of the reasons that Oracle App. Server can not start is the port being used by another application. It could be port HTTP Port(default to 80) or SSL Port(default to 443).
Let's assume we are using Windows Operating System:
To find out that the port (i.e: SSL Port - 443) is being used by another application, type this in Command Prompt:
If the port not used, then "Connection Refused" will be displayed, otherwise the system will display "Connected".
If "Connected" is displayed, it means an application already listening that port. To find out which application use that port, we can follow this steps:
a. In command prompt, type:
b. Look for appropriate port and notice the PID number
c. To find out what application have that PID, type this in command prompt:
After terminating another application using that Oracle Application Server port, you can try to restart the Application Server.

telnet localhost 443
If the port not used, then "Connection Refused" will be displayed, otherwise the system will display "Connected".
If "Connected" is displayed, it means an application already listening that port. To find out which application use that port, we can follow this steps:
a. In command prompt, type:
netstat -anoThe system will display list of ports on which the computer is listening and display the Process ID (PID) number.
b. Look for appropriate port and notice the PID number
c. To find out what application have that PID, type this in command prompt:
tasklistd. To kill that application from command prompt, you can use this command:
taskkill /PID/F
After terminating another application using that Oracle Application Server port, you can try to restart the Application Server.
