On the General tab of the Web Application page, change the Context Root
or the Description, if desired.
In Cluster Profile, enable or disable high-availability.
If availability is enabled for an application, it must also be enabled at
all higher levels (named configuration and web container or EJB container) as well.
To view the targets on which the application has been enabled, click the
Targets tab. You can enable or disable applications on one or multiple targets.
See Managing Targets.
