Sometimes you might find issues starting up your SAP services, with a error that the service is not able to bind to a particular port.
In the example below, I was not able to start the SMTP service from SMICM.
This mean, there could be another service that is already using this port.
Lets find out:
netstat -nepal | grep 25
Now we have the process ID. Lets see what is this process all about:
ps -ef | grep 6760
Postfix was using my service, which was not required.
Kill/Stop the service that is not required before starting your service again.
In my example:
# postfix stop
Make sure that you disable the unwanted service from starting up next time when you reboot the server using chkconfig:
# chkconfig postfix off
