Starting the WebLogic Administration Server
Administration Guide 2-15
Note: If you do not have Service Pack 2 of WebLogic Server 6.1 installed, the
new administration machine must have the same host name as the machine that
hosted the failed Administration Server.
2. Make your application files available to the new Administration Server by
copying them from backups or by using a shared disk. Your application files
should be available in the same relative location on the new file system as on the
file system of the original Administration Server.
3. Make your configuration and security files available to the new administration
machine by copying them from backups or by using a shared disk. These files are
located in the
/config/myDomain directory of the Administration Server, where
myDomain is the name of the domain being managed by the Administration
Server.
4. Restart the Administration Server on the new machine with the addition of the
following argument on the command line:
-Dweblogic.management.discover=true
This argument will force the Administration Server to discover the presence of
the Managed Servers that are running. (If you omit this property, the
Administration Servers still executes the discovery. Make sure, however, that
this property is either not defined or not set to
false in the command line you
use to start WebLogic Server.)
When the Administration Server starts, it communicates with the managed
servers and informs them that the Administration Server is now running on a
different IP address.
Server Startup Process
When you start a WebLogic Server, it takes the following actions:
1. Retrieves its configuration and bootstrap security data.
An Administration Server retrieves the configuration and security data from the
domain’s configuration files. A Managed Server contacts the Administration
Server for its configuration and security data. If you set up SSL, a Managed
Server uses its own set of certificate files, key files, and other SSL-related files
and contacts the Administration Server for the remaining configuration and
security data.
