Application Management
Overview
Applications are key to the operation of many businesses. The cost of an unavailable
application can result in:
•
Revenue loss. Many companies sell their ability to deliver services any time of the
day or night. If the application responsible for providing the service is unavailable,
the customer might call another supplier.
•
Lost productivity. Information-based companies rely on computer applications. The
time lost because of an unavailable application results in lost productivity.
•
Penalties. Companies that provide transaction services often guarantee 7x24
availability and, if they do not meet those guarantees, pay penalties to their
customers.
•
Support and operations costs. Recovering from an application problem or failure
results in support and operations costs.
Therefore, application management is probably one of your major responsibilities. This
section provides guidelines for managing operations-oriented applications. The section
ends with a check list that summarizes the main points of application management.
What Is Application Management?
The Tandem application environment consists of application subsystems that enable you
to develop and run high-performance, high-volume, and highly available online
transaction-processing (OLTP) applications. The application subsystems that make up
the Tandem application environment include NonStop Transaction Services/MP
(NonStop TS/MP), NonStop SQL/MP, and NonStop Transaction Manager/MP (NonStop
TM/MP).
Application management includes:
•
Working with application developers to ensure that the information and support you
need to run the applications are available. This step is the most important part of
application management.
•
Managing change. Change and configuration management help you ensure that
changes proceed smoothly and that the system is configured for optimal
performance. See Section 7, “Change and Configuration Management,” for more
information about change control and configuration management.
•
Running online, batch, and client/server applications on production systems. After
installing the applications, the staff has to start and then monitor them. The system
operations requirements for this step depend on the type of application (online,
batch, or client/server) and the Tandem products you are using.
