Manage Availability Service

Use this page to manage high-availability of HTTP and RMI-IIOP sessions and single sign-on of web applications (Enterprise Edition only).

The following table describes the fields and buttons on the page. The left column lists the fields and buttons; the right column describes the functionality.

Field or Button
Description

Instance Level Availability:

If the checkbox is checked, high-availability of HTTP and RMI-IIOP sessions and single sign-on of web applications are enabled at the server instance level.

If you enable Instance Level Availability, availability is enabled for all sublevels in the server instance unless you disable it at a sublevel. For example, if you enable Instance Level Availability, you can still disable web container availability at the web container level.

You should set the same availability value for all instances in a cluster to ensure consistent behavior.

Ejb Container Availability:

Specifies at what level the high-availability features of the EJB container are enabled. Select one of the following options:

Specified by Instance: Uses the high-availability settings from the server instance, as specified in the Instance Level Availability field.

Enabled: Enables high availability for the EJB container.

Disabled: Disables high availability for the EJB container.

Web Container Availability:

Specifies whether the high-availability features of the web container are enabled. Select one of the following options:

Specified by Instance: Uses the high-availability settings from the server instance, as specified in the Instance Level Availability field.

Enabled: Enables high availability for the web container.

Disabled: Disables high availability for the web container.
