DATABASE MANAGEMENT
Depending on the amount of memory available during rebuilding, the space required in the temporary folder for each view being rebuilt is approximately two times the size of the largest view or two times the size of all the data in documents, whichever value is greater. It is recommended that you change the location of the temporary files to a different drive from the Domino data folder. Putting the temporary folder on a different drive distributes disk I/O and ensures that there is enough space to rebuild views. Domino is very conservative when estimating the amount of disk space needed for optimized view rebuilds so that it won't spend unnecessary time sorting data only to discover that there's inadequate disk space. Make sure that the temporary folder you specify has plenty of disk space available.
To change the temporary folder used for view rebuilds, add the setting View_Rebuild_Dir to the server's NOTES.INI file and specify a new location. For example, add:
insufficient disk space at directory. Estimate may need
x million bytes for this view. Using standard rebuild instead.
