Postdeployment

In the postdeployment stage of the life cycle, you run a deployed solution in a production environment. The following tasks are involved in the operations phase of the life cycle:

• Monitoring. These tasks include regular monitoring of system performance and system functions.

• Maintenance. These tasks include everyday administrative functions, such as adding new end users to a system, changing passwords, adding new administrative users, changing access privileges, performing regular backups, and so forth.

• Performance tuning. These tasks include the use of regular monitoring information to find bottlenecks in system operations and attempting to eliminate those bottlenecks by changing configuration properties, adding capacity, and so forth.

• System enhancements and upgrades. These tasks include adding new Java ES components to a system to add new functionality or to replace non-Java ES components. In either case, these changes might require a redesign of the system, beginning with the initial phases of the solution life cycle. Upgrade tasks are more limited, usually amounting to upgrades of Java ES components

  Each Java ES component has its own administration tools for configuring, tuning, or managing its operations. The goal is to provide a common monitoring and management infrastructure and administration tools for managing the system as a whole.
