Administering a BEA Tuxedo System at Run-Time

What Is an Event

An event is a state change or other occurrence in a running application (such as a network connection being dropped) that may require intervention by an operator, an administrator, or the software. The BEA Tuxedo system reports two types of events:

System-defined events, which are situations (primarily failures) defined by the BEA Tuxedo system, such as the exceeding of certain system capacity limits, server terminations, security violations, and network failures.

Application-defined events, which are situations defined by a customer application, such as the ones listed in the following table.

In an application for this type of business . . .	An occurrence of this situation may be defined as an "event" . . .
Stock brokerage	A stock is traded at or above a specified price.
Banking	A withdrawal or deposit above a specified amount is made.
Banking	The cash available in an ATM machine drops below a specified amount.
Manufacturing	An item is out of stock.

Application events are occurrences of application-defined events, and system events are occurrences of system-defined events. Both application and system events are received and distributed by the BEA Tuxedo EventBroker component.
