Description

Various Domino subsystems (HTTP debug trace, semaphore and memory trace, NSD dumps, certmgr debug) write diagnostic files by default into the IBM_TECHNICAL_SUPPORT subfolder of the data directory. On large servers, this folder fills up quickly and competes with mail and application NSFs for disk space / IO. With LOGFILE_DIR, you can redirect the debug logs to a separate, larger volume – without moving the data directory itself.

Example configuration

LOGFILE_DIR=D:\\domino\\diag

Notes & pitfalls

  • The directory must already exist and be writable by the Domino service account.
  • Takes effect after a server restart (some subsystems accept changes only when their log files are next created).
  • Plan backup and retention for the diagnostics directory separately from the data directory.
  • Incorrect paths cause NSD / console data to silently fall back to the default directory – verify after changing.
