How to avoid memory dumps being overwritten on a Domino server

Technote (FAQ)


Question

When you create a memory dump on your Domino server, the file is always saved with the same file name (memory.dmp). As a result, if the preceding memory.dmp file is not removed (or renamed) prior to initiating a subsequent memory dump, the information in the file will be overwritten. How can this be avoided?

Answer

Beginning with Release 5.0.9 of Domino, the following new variable can be dynamically set:
DEBUG_MEMDUMP_TIMEDATE=1

This will change the file name to include the date and time that the memory dump was created.

Note DEBUG_MEMDUMP_TIMEDATE was not implemented in Domino 6.0. Starting with 6.0.1 the memory dumps now have a unique file name that includes date and time. In Notes Domino 6 (for Win32) the file is placed into: /data/ibm_technical_support/, and has a file format of memory_servername_2003_mm_dd@time.dmp. There is no longer a need for the notes.ini parameter: DEBUG_MEMDUMP_TIMEDATE=1.
