- Administering
  - Overview of administering a WebSphere Commerce site
    In WebSphere Commerce the person who performs administrative tasks is called a Site Administrator. The Site Administrator installs, configures, and maintains WebSphere Commerce and the associated software and hardware. The administrator responds to system warnings, alerts, and errors, and diagnoses and resolves system problems. Typically, this person controls access and authorization (creating and assigning members to the appropriate role), manages the Web site, monitors performance, and manages load balancing tasks. The Site Administrator might be responsible for establishing and maintaining several server configurations for different stages of development such as testing, staging, and production. The Site Administrator also handles critical system backups and resolves performance problems.

    WebSphere Commerce provides facilities for logging. For existing customers, ECTrace and ECMessage are still supported. For new implementations, use the WebSphere Application Server recommendation for logging and tracing.
  - Business auditing
    Business auditing is the capturing of the business logic and objects during a WebSphere Commerce operation. You may want to audit your business for various reasons: generic, such as to review various tasks performed weekly; or specific, such as to track the steps involved in a particular Customer Service Representative's order. A report on business auditing is available in the Administration Console.
  - Business events
    Each time that a command triggers a business event, a record is added to the BUSEVENT database table to persist data from the event. Event listeners and external systems (such as the Marketing component, a back end order management system, or an external analytics system) can use this data to perform further processing.
  - Staging server
    The WebSphere Commerce staging server is a part of the production environment where business and technical users can update and manage store data and preview changes. The changes can then be propagated to the production server.

Adding horizontal cluster members

After you federate your WebSphere Commerce environment, you can configure horizontal clustering. Clustering provides failover protection and provides workload balancing.Clustering with horizontal cluster members refers to the traditional practice of defining cluster members of an application server on multiple physical machines. This process allows a single application to span several machines while presenting a single system image. Clustering with horizontal cluster members can provide increased throughput and high availability.

Before you begin

Complete the installation of a WebSphere Commerce node.
Create a WebSphere Commerce instance. For more information, see Creating an WebSphere Commerce instance.
Before you cluster a WebSphere Commerce instance, back up the WebSphere Application Server administrative configuration. If clustering fails during the clustering process, you can restore the original configuration.
- Backing up and recovering the application server environment
Federate the WebSphere Commerce node into a deployment manager cell.
