Postdeployment

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

• Monitoring. Includes regular monitoring of system performance and system functions.

• Maintenance. Includes 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. Includes 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. Includes adding new Java ES components to a system to add new functionality or to replace non-Java ES components. 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.
