Change Management
Change Management
Change management includes the tasks required to manage the maintenance and
growth of your NonStop system. Change management involves managing all hardware,
software, and procedural changes and includes all of the tasks required to properly
manage change within the operations environment. For example, some of the tasks
included in this discipline are:
•
Anticipating and planning for change
•
Controlling the introduction of change
•
Installing and implementing changes to system software and hardware, application
subsystems, communications subsystems, and application software
Tandem systems are engineered so they can grow and change in response to business
needs. They also provide a flexible processing environment that allows you to add
terminals, applications, and databases as needed while the system is running. For
guidelines and suggestions on managing the change environment, refer to Section 7,
“Change and Configuration Management.”
For comprehensive information about managing change and for information about
change management tools provided by Tandem, refer to the Availability Guide for
Change Management.
Configuration Management
Change and configuration management are interrelated functions. Configuration
management includes the tasks required to manage and administrate the configuration
of system software and hardware, application subsystems, communications subsystems,
and application software. For example, some of the tasks included in this discipline are:
•
Maintaining and tracking configuration documentation
•
Defining and managing names for configuration components and maintaining the
relationships between configuration components
•
Controlling, maintaining, and distributing multiple versions of software such as
operating system and subsystem object code, Tandem and third-party application
object code, and in-house application source and object code
Tandem provides a number of tools to help your staff with change and configuration
management tasks. For guidelines and suggestions on managing the configuration
environment, refer to Section 7, “Change and Configuration Management.”
