The percentage of the cluster size.

Use Record free chain search depth factor (-recspacesearchdepth) to specify how far into the record free chain the database engine searches for a block with enough free space to store the data associated with a record create or update before a new cluster of data is allocated. The value is a percentage of the cluster size with a minimum of 3 blocks.

To change this parameter while the database is running, use PROMON or the _DbParams VST.
