Description

DEBUG_NSF_ALL=1 simultaneously turns on debug output for all NSF subsystems (open/close, note read/write, lock management, cache, replication). The result is extremely detailed console/log output that helps narrow down NSF errors that are hard to reproduce – such as silent corruptions or locking issues.
Because the output is very voluminous and produces noticeable load, the parameter should be active only during the diagnosis window.

Example configuration

DEBUG_NSF_ALL=1
Debug_Outfile=/local/notesdata/IBM_TECHNICAL_SUPPORT/nsf_debug.log

Notes & pitfalls

  • Output can reach several GB per hour – set a dedicated Debug_Outfile.
  • Complements DEBUG_THREADID=1, DEBUG_TIMINGS=1.
  • In production, enable only under specific conditions (HCL Support request).
  • Be sure to disable after diagnosis (set config DEBUG_NSF_ALL=0).
  • Takes effect immediately after set config – no restart required.
