The forum is currently being migrated to a new host. While the migration happens, the old server is still available. Once the new machine is ready, I will copy the database to the new machine. Feel free to ask and answer questions in the meantime.

When using "Alter database calibrate" is the calibration dependent on the database file size?

Yes. Calibration involves sampling I/O retrieval times for each dbspace, and the larger the dbspace the more sampling is performed, up to a maximum of 3200 pages with the 12.0.0 release.
