Description

NIFNSF (NIF on NSF) moves the view indexes of a database into a separate file (<file>.ndx). This makes the NSF significantly smaller and allows I/O paths for data pages and index pages to be physically separated – typically NSF on regular storage, NDX on SSD.
CREATE_NIFNSF_DATABASES=1 instructs Domino to automatically create newly created databases or those migrated with compact -upgrade in the NIFNSF layout.

Example configuration

CREATE_NIFNSF_DATABASES=1
NIFBasePath=D:\NIFNSF

Notes & pitfalls

  • Requires ODS 52 or higher (Create_R10_Databases=1 as a prerequisite).
  • NIFBasePath must be set and located on fast, local storage.
  • Review the backup strategy: NSF and NDX must be backed up consistently.
  • Loss of the NDX means an index rebuild – the NSF itself remains intact.
  • The change takes effect only after a server restart and affects only newly created/migrated NSFs.
