Memexer - Digital Equipment 3300R Service Manual

memexer

The memexer command tests memory by running a specified number of memory
exercisers. The exercisers are run in the background and nothing is displayed unless an
error occurs. Each exerciser tests all available memory in twice the backup cache size
blocks for each pass.
To terminate the memory tests, use the kill command to terminate an individual diagnostic
or the kill_diags command to terminate all diagnostics. Use the show_status display to
determine the process ID when terminating an individual diagnostic test.

>>> kill_diags
>>>
Number of memory exercisers to start. The default is 1.
The number of exercisers, as well as the length of time for testing, depends
on the context of the testing. Generally, running three to five exercisers for
15 minutes to 1 hour is sufficient for troubleshooting most memory
problems.
