System Maintenance Strategy
1.2 Product Service Tools and Utilities
• Operating System Exercisers (OpenVMS UETP)
The User Environment Test Package (UETP) is an OpenVMS software
package designed to test whether the OpenVMS operating system is
installed correctly.
RECOMMENDED USE: Use UETP as part of acceptance testing to
ensure that the OpenVMS operating system is correctly installed.
UETP is also used to stress test the user’s environment and
configuration by simulating system operation under heavy loads.
• MicroVAX Diagnostic Monitor (MDM)
The loadable diagnostic MDM requires a minimum of Release 139 to
support VAX 4000 Model 500A/505A/600A/700A/705A systems. Consult
your
MicroVAX Diagnostic Monitor User’s Guide
for instructions on
running MDM.
RECOMMENDED USE: MDM is used primarily for testing Q–bus
options.
• Loopback Tests
Internal and external loopback tests can be used to isolate a failure
by testing segments of a particular control or data path. The loopback
tests are a subset of the ROM-based diagnostics and MDM diagnostics.
RECOMMENDED USE: Loopback tests can be used to isolate problems
with the console port, DSSI adapters, Ethernet controller, and many
common Q–bus options. Refer to Section 5.7 for instructions on
performing loopback tests.
• Crash Dumps
For fatal errors, the OpenVMS operating system will save the contents
of memory to a crash dump file, e.g., fatal bugchecks.
RECOMMENDED USE: Crash dump file analysis should be
performed by support. Saving a crash dump file for analysis requires
proper system settings. Refer to your OpenVMS operating system
documentation for instructions.
