DATABASE MANAGEMENT
Multiple Fixup tasks run simultaneously at server startup to reduce the time required to fix databases. The number of Fixup tasks that IBM® Lotus® Domino® runs by default at startup is equal to two times the number of processors available on the server. Although this default behavior should be adequate in most circumstances, you can edit the NOTES.INI file to include the Fixup_Tasks setting. The actual number of tasks run is the smaller of the configured number of tasks that can run and the number of databases that require fixing. For example, if you set Fixup_Tasks to 4 but only one database requires fixing, then only one Fixup task runs.
Keep in mind that after you set up transaction logging, Fixup is not needed or used to bring databases back to a consistent state.
Ways to run Fixup manually
Use Domino Administrator to use any of these methods to run Fixup manually to fix a corrupted database. With each of these methods, you can customize how Fixup runs.
