Description

The Compact task is relatively quiet in normal operation. As soon as problems arise – stuck NSFs, errors during ODS upgrade, or unexpectedly slow runs – Debug_Compact provides structured logs for each processed database.
Output goes to the current Debug_Outfile (or the console). At levels 2/3, several MB per Compact run can be produced quickly – enable only temporarily.

Example configuration

Debug_Compact=2
Debug_Outfile=/local/notesdata/IBM_TECHNICAL_SUPPORT/compact_debug.log

Notes & pitfalls

  • Enable before nightly Compact runs, then disable again afterwards.
  • Complements Debug_Outfile, Compact_Max_Threads, DBMT_*.
  • Use level 3 only for deep troubleshooting – high I/O load.
  • Logs land in the IBM_TECHNICAL_SUPPORT directory depending on the Debug_Outfile setting.
  • Takes effect directly after set config Debug_Compact=...; no restart required.
