Start/notes.ini Parameters/UPDATE_DISABLE_FULLTEXT

UPDATE_DISABLE_FULLTEXT

Disables automatic full-text index maintenance by the Update task. The FT indexes are then only refreshed via scheduled Updall runs.

Description

  • By default, the Update task refreshes not only view indexes but also full-text indexes with Immediate or Hourly frequency.
  • With many databases that have a full-text index, or with a few very large DBs with high update volume, the Updater queues can grow significantly.
  • UPDATE_DISABLE_FULLTEXT=1 switches off FT maintenance by the Updater entirely. Instead, FT maintenance is scheduled via additional programdocs running Updall (e.g. every 30 minutes or once per hour).
  • View indexes are not affected — there is UPDATE_DISABLE_VIEWS for that.

Example

UPDATE_DISABLE_FULLTEXT=1
  • The Updater only maintains view indexes.
  • Complementary programdoc: Updall e.g. every 30 minutes for the few databases that really need up-to-date FT indexes.

Notes

  • Takes effect only after a server restart or restart of the Update task.
  • Does not act retroactively on FT index builds already in progress.
  • Recommended companion measures:
    • set up a programdoc for Updall (e.g. every 30 minutes),
    • delete unneeded full-text indexes entirely,
    • additionally UPDATE_DISABLE_VIEWS=1 if view updates also cause problems.
  • Not needed on servers with normal load — the default configuration is more efficient there.
