Description

According to HCL product documentation:
Specified in seconds, this setting controls how often the run time database directory cache is validated against the physical disk to check for files changed, added or deleted outside of Notes. A shorter interval will result in greater I/O utilization. The default is 900 seconds (15 minutes). This replaces DBDIR_REFRESH_INTERVAL.
In the HCL documentation, DBDIR_DIRECTORY_SCAN_INTERVAL and DBDIR_REFRESH_FROM_DISK are listed with almost identical descriptions of their effect: both replace the old DBDIR_REFRESH_INTERVAL and control disk validation of the run-time cache. In current Domino versions, DBDIR_DIRECTORY_SCAN_INTERVAL is mainly recommended — DBDIR_REFRESH_FROM_DISK remains documented as a valid alternative identifier.

Example configuration

DBDIR_REFRESH_FROM_DISK=900

Notes & pitfalls

  • Value in seconds.
  • Shorter intervals → faster detection of external changes, but noticeably more disk I/O.
  • Functionally largely identical to DBDIR_DIRECTORY_SCAN_INTERVAL.
  • Replaces the older parameter DBDIR_REFRESH_INTERVAL.
  • Complementary to DBDIR_CACHE_SAVE_TO_DB_INTERVAL.
