This setting is used to block allocate Itemnum keys. Because there is a limited set to total key values, it is best not to allocate more than 100 at a time.
This setting corresponds to the Document Handle Block Size setting in the OnBase Client's Process Tuning Parameters dialog box. A document handle is a unique identifier for a document. This setting will be defaulted to one (1), which indicates that each time a process creates a new document, a new document handle is retrieved from the database. Setting the block size to a higher number will cause a group of document handles to be retrieved from the database, reducing the number of times that the database must be queried for document handles. The disadvantage of retrieving document handles in blocks is that each time a process finishes, any unused document handles will be wasted. Fortunately, a total of over four billion document handles are available. Depending on the number of documents created by a process, setting the Document Handle Block Size to 10 or 100 can speed up the process. The range of values is 1 - 1000.
