Startup behavior of an application:

When you need to disable the auto-start option of an application go to “Enterprise Applications > Name of Application > Target specific application status”, select Application Server and click “Disable Auto Start”.

To adjust the startup order go to “Enterprise Applications > Name of Application > Startup behavior” and adjust to Startup order by changing the field-value.
Applications with lowest value are started first.
Applications with the same value are not startet in an specific order.

Another way of doing same is. Go to your profile directory and open deployment.xml.

>> config >> cells >> >> applications >> >> deployments > > deployment.xml.

For the tag targetMapping make the attribute enable=”false” . True means application will start on startup.
