Service Packs and WebLogic Server Instances
All WebLogic Server instances in a domain must run the same version of the
WebLogic Server software. The Administration Server must also have the same or
later service pack installed as the Managed Servers in its domain. For example, the
Administration Server could be running version 8.1, Service Pack 1 while the
Managed Servers are running version 8.1 without Service Pack 1.
System Administration Tools
Using JMX as the underlying architecture, system administration tools are provided
for a variety of management functions. An Administration Server must be running
when you use system administration tools to manage a domain.These tools are
discussed in the next sections.
Security Protections for System Administration Tools
All system administration operations are protected based on the user name used to
access a system administration tool. A user (or the group a user belongs to) must be a
member of one of four security roles. These roles grant or deny a user access to various
sets of system administration operations. The roles are Admin, Operator, Deployer,
and Monitor. You can also set a security policy on WebLogic Server instances in a
domain. For more information, see “Protecting System Administration Operations” on
page 8-1.
System Administration Console
The Administration Console is a Web Application hosted by the Administration
Server. You can access the Administration Console using a Web browser from any
machine on the local network that can communicate with the Administration Server
(including a browser running on the same machine as the Administration Server). The
