It is executed like any other PROUTIL function, there are however a number of prerequisites to using the utility: Always have a current backup of the database. The server must be down and the database not in use. If possible, bring the database into sync by having a normal shutdown where there are no incomplete transactions to be backed out.
Truncate the before-image BI file. Do not skip this last step. The BI file must be truncated. Only if there is BI corruption will an error be received during the truncation.
Events leading up to this need to scan may also signal that there is bi corruption.
