Creating and Configuring WebLogic Server Domains 11-9
! After you enable the administration port, you must establish an SSL connection
to the Administration Server in order to start any Managed Server in the domain.
This applies whether you start Managed Servers manually, at the command line,
or using Node Manager. For instructions to establish the SSL connection, see
“Booting Managed Servers to use Administration Port” on page 11-9.
! After enabling the administration port, all Administration Console traffic must
connect via the administration port.
Administration Port Requires SSL
The administration port requires SSL, which is enabled by default when you install
WebLogic Server. If SSL has been disabled for any server instance in your domain,
including the Administration Server and all Managed Servers, re-enable it using the
Server--> Configuration-->General tab in the Administration Console.
Ensure that each server instance in the domain has a configured default listen port or
default SSL listen port. The default ports are those you assign on the
Server-->Configuration-->General tab in the Administration Console. A default port
is required in the event that the server cannot bind to its configured administration port.
If an additional default port is available, the server will continue to boot and you can
change the administration port to an acceptable value.
By default WebLogic Server is configured to use demonstration certificate files. To
configure production security components, follow the steps in “Configuring the SSL
Protocol” in Managing WebLogic Security.
Configure Administration Port
Enable the administration port as described in “Enabling the Domain-Wide
Administration Port” in Administration Console Online Help.
After configuring the administration port, you must restart the Administration Server
and all Managed Servers to use the new administration port.
Booting Managed Servers to use Administration Port
To reboot Managed Servers to connect to the Administration Server’s administration
port, the command line or start script must specify the
https:// prefix, rather than
http://, as shown below.
