When trying to create agents for a RAC database, the installer wizard is displaying the wrong host name.
The host is having two network interfaces and the one which the installer is displaying is not accessible for external applications.
How to force the installer to use the correct network interface / host name?
The database installer is picking up the host names from the Oracle table gv$instances (select instance_name, host_name from gv$instance;).
The host name the installer is providing can be modified. Click on the "Edit" icon and enter the correct host name that the installer will use the correct network interface.
