To truncate the bi file: proutil <dbname> -C truncate bi
To remove bi extents that are not in use:
The V9, V10 syntax is: prostrct remove <dbname> bi
The V8 syntax is: prostrct remove <dbname> b
If you want your last BI extent to not be fixed, then you will need to remove the last fixed BI extent prior to adding a new non-fixed one.
With a file "add.st" containing:
b . /dir1/dir2
Issue the prostrct add command to add the variable length extent back to a database once all bi extents have been removed.
prostrct add <dbname> add.st
