Description

According to the HCL product documentation, Updaters defines the number of Update server tasks that can run simultaneously on the server.
Verbatim from the HCL documentation:
  • You must shut down and restart the server for this setting to take effect. (Changes only take effect after a server restart.)
  • Default: None, although if this setting is omitted, only a single Update task can run at a time. (Without an entry, exactly one Update task runs.)
Multiple parallel Update tasks can speed up index updates on servers with many databases — each task can independently refresh views and maintain full-text indexes.
The HCL help page Running multiple Update tasks (admn_runningmultipleupdatetasks_t.html) additionally describes that further Update tasks can be started at runtime via Domino Administrator Task → Start.

Example configuration

Updaters=2
With Updaters=2, the server starts two Update tasks in parallel.

Notes & pitfalls

  • Effective only after a server restart.
  • HCL note from the Running multiple Update tasks help page: when manually starting additional Updaters in Domino Administrator, choose Update, not Update all.
  • Without an entry, exactly 1 Update task runs — that is the implicit default.
  • According to HCL, there is no direct GUI equivalent; the value can be maintained via the NOTES.INI Settings tab of a configuration document.
