Utility-Class Software; Utility Applications Guidelines - Nortel TAPI Reference Manual

24 Chapter 2 Hardware and software guidelines

Utility-class software

Certain utility-class software products, such as hardware diagnostics or backup
utilities, require less system resources and can be installed if they are in strict
compliance with the recommendations provided in this document. Utilities that
cause system problems and degrade performance must never be installed on the
TAPI server, including the following:
• Screen savers
• Disk compression utilities
• Memory-saving utilities that "reclaim" memory unused by Microsoft
applications.

Utility applications guidelines

You can install utility-class applications on the TAPI server when they conform to
the following guidelines:
• During run-time, the utility must not degrade the TAPI system beyond an
average of 50% of CPU usage. The utility must not reduce the minimum
amount of free hard disk space required by Symposium TAPI Service
Provider, the Windows operating system, and Symposium Agent if it is
installed on the server.
• The utility must not cause any improper software shutdowns or
out-of-sequence shutdowns.
• The utility must not attempt to administer the Symposium TAPI SP software.
• If the utility has its own database, it must not affect the Symposium database.
• The installation or removal of a utility should not impair the operation of
Symposium TAPI SP software. If a conflict occurs, such as can occur
between conflicting dll files, it may be necessary to reinstall the server.
• Before you put the TAPI server into operation, you must perform tests to
ensure that you meet these guidelines. During fault diagnosis Nortel Networks
GNTS can ask for the results of these tests and request the removal of
third-party software.
