CEI

This section describes a simple scenario that demonstrates how the CEI can be configured using the administrative console.

You could also turn off validation of CEI events, once it has been verified that the emitted events are valid.

The CEI infrastructure enables you to create and distribute the events in a uniform fashion.

Data is encapsulated in Common Base Events by means of event emitters and is transmitted via the CEI.

We are now ready to install the CEI applications.

The CEI is used to generate relevant events for measurements of business metrics to be computed and displayed in business dashboards.

Before a common base event is sent to the CEI server by the emitter, it is validated to ensure all the required fields have been set.

Therefore the default CEI bus transmission profile must be modified to account for this change.

When you've finished any CEI modification needed, click Summary, and verify that all information is correct, as shown in Figure 14.

To do this, you'll need to log on to your Application Server administration console and modify the CEI configuration slightly.

WebSphere Process Server builds on and leverages CEI to emit a specific set of events for each SCA service component.

Emitters configured to send events asynchronously will post CBEs to a JMS queue used by the CEI server.

CEI does not provide a direct access to the event database but it does provide the APIs to query the database.

The CEI provides a point of integration to consolidate events from a number of potentially disparate and diverse sources.

You also learned how, with the correct configuration, you can examine the CBE messages which have been distributed over CEI.

The Common Event Infrastructure can be configured to receive, persist, and distribute events.

Also check the checkbox that relates to installing the BPC Web client, and for now leave the checkboxes for CEI unchecked.

This section brings together the information described above to show how a common base event can be created and sent to the CEI server.

Emitters may be associated with a filter so that only CBEs containing specific information are sent to the CEI.

The sample project provides a ready configured "Common Base Event" created within the "CEI" touchpoint.

CEI's bags have also been named Best of Show for the past two years in the Flexographic Technical Assoc.

You should see the connector status update in the command window as it receives the message from the CEI queue, as shown in Figure 10.

In this instance, we took CBE messages from CEI and outputted a subset of the message to a file.

The CEI receives system or business information encapsulated in a Common Business Event (CBE).

When the emitter receives a CBE, it will use this filter to determine if the event should be sent to the CEI server.

The scope of both CEI data sources can be controlled by specifying the SCOPE attribute in the OracleResponseFile. txt file.

The subsequent screen (Figure 32 ) allows you to select the CEI Emitter Factory JNDI name.

The event server profile settings define the persistence and distribution behavior of the CEI server.

During execution, the CEI infrastructure enables the monitoring of the process performance.

CEI has done an amazing thing in giving recent college graduates such fulfilling, challenging, and deeply important work.

CEI input hand controllers are specifically designed to operate CEI's electrohydraulic valves and actuators.

Now, you can install the two CEI applications: one implements the CEI engine and the other allows asynchronous publishing of CEI events.

CEI provides two interfaces to receive events: Event Access interface and Event Distribution interface.

When the CEI server receives an event (and provided that event distribution is enabled), it attempts to match the event to an event group.

CEI provides the standard interfaces and services for WebSphere applications to create and emit event objects.

CEI provides the run-time environment for propagation, persistence, query and distribution of events.

The event bus JNDI name specified in the transmission profile is the JNDI Name of the CEI server EJB interface.

CEI's suggested Human Achievement Hour activities include taking a hot shower, watching TV, or phoning friends.

Once the CEI server receives a CBE, it may be persisted and or distributed.

In a future article of this series, we show how to do business process monitoring using CEI.

It creates the CBE and provides methods to populate it with data before sending it to the CEI server.

For the time being, leave the JNDI name of the CEI emitter factory to the default.

Switching off audit log and CEI means to disable the intended means to do auditing and monitoring.

This method emits an event to the CEI server with the properties set as extended data elements in the CBE.

CEI provides the ability to store, update and distribute events to event consumers who listen on JMS topics.

This will automatically install CEI with default configuration on the server.

You can use Common Event Infrastructure (CEI) APIs to generate relevant process events.

We will delay the creation of this database to the section where we talk about configuring CEI.

In addition, any application that generates events in the Common Event Infrastructure (CEI) can also be monitored.

In the Silver Topology, the CEI is configured as part of the WPS cluster.

Now that you've imported the project, let's enable the event to accept CBE messages from CEI.

Emitters are used by event sources to send CBEs to the CEI server and are configured using an emitter factory profile.

The CEI may receive events from many event sources but this article will consider only two.

The CEI database is created by executing a generated DDL script and has a default name of "event. "

These two commands not only installed the applications, but they also created some resource definitions for CEI.

These products support the use of CEI as a mechanism for passing events in CBE format.

CEI is an event notification and event transmission framework that is currently provided in multiple products.

An administrator can configure the CEI run-time environment.

The asynchronous emitter sends events to the CEI server using JMS.

The full event access API has been delivered in the production release of the CEI.

Each time an event definition is modified or added, an event will be sent to the CEI server.

The CEI provides a Java programming interface for creating an event.

There are two of them one that implements the CEI engine and another that allows asynchronous emission of CEI events.

The destinations are intended for receiving events from the CEI.

Directory that can be used to perform the following operations on the CEI.

When the actions are forwarded to the CEI server, Monitor can process them.

You can create this database later in the section that configures CEI.

Run this command to create the CEI database on a remote system: cr_event_db2. bat client .

Applications running in both J2EE and J2SE environments act as event sources to create and send events to the CEI server.

See the Select Monitor model CEI options in the Monitor Information Center.

Obtain an emitter and send the events to the CEI server.

This code sends an event to the CEI server without the need to create a CBE first.

Compared to CEI APIs, the advantage of using ECSEmitter is that it preserves the event context.

You now need to create two physical destinations on the bus for CEI.

There is one database per CEI deployment target.

The cross-cell files are required to support a remote CEI server on Application Server V6. 1.

The event selector string should be a valid XPath expression that is used by the CEI server to match events.

We can now configure and install the Common Event Infrastructure on the CEI cluster.

CEI currently supports V1. 0. 1 of the CBE model described above.

To get the port value, open the Application Server administrative console and find the CEI server Application Server bootstrap port address.

CEI data sources: The CEI data source creation is a two step process.
