Detailed information for the notes.ini Keyword: 

NSD_Run_MemCheck


Short Description: nclude the Memcheck in the NSD file to be created when the next server crash occurs.

Description:

Use this variable to include the Memcheck in the NSD file to be created when the next server crash occurs

Valid Values are:

0 = do not incorporated memcheck output in NSD

1 = incorporated memcheck output in NSD

If a server crash occurs when this parameter is set, then the memcheck output is incorporated (integrated) into the NSD file that is created.

"Memcheck runs a scan of all shared memory segments in use by Notes processes, as well as the individual stack memory allocated to each process. Memcheck determines if the memory segment format matches the expected format for the memory segment. If Memcheck does not find what it expects in the memory segment, it dumps the appropriate memory segment pool into a file with the following syntax: memcheck.__mm_dd@hh_mm.dump"

Question

How is the MEMCHECK function for a Lotus® Domino® server on the i5/OS® (System i™) used?

Answer

MEMCHECK was added to the Domino for iSeries code at 6.0.5/6.5.4. Before those releases, MEMCHECK did not run on the i5/OS.

There are two ways to trigger MEMCHECK on the i5/OS.

1. load memcheck -k curr -d err -v 2

2. NSD_RUN_MEMCHECK=1

The first method listed is a Domino console command. The last parameter in the string "2" is the verbose level of the output. This can be 1, 2, 3, or 4. Running this Domino console command creates a text file in the IBM_TECHNICAL_SUPPORT subdirectory called:

memcheck_mm_dd_yy@hh_nn_ss.log. (Where mm is month, dd is day, yy is year, hh is hour, nn is minute, and ss is second.)

The second method is a Domino server NOTES.INI parameter. If a server crash occurs when this parameter is set, then the memcheck output is incorporated into the NSD file that is created.





Default value:
None

Syntax:
NSD_Run_MemCheck=0/1

Example:
NSD_Run_MemCheck=1

UI equivalent:
There is no kown UI setting for this notes.ini variable. But you can specify this setting in the notes.ini settings tab of the configuration settings document.
