You can safely use IQ UTILITIES to create your own versions of documented system procedures that report on information in the database.
For example, sp_iqspaceused displays information about used and available space available in the IQ main and IQ temporary stores. Verify that the procedure you create from a system stored procedure has the correct owner.
Do not create your own versions of system procedures that control IQ operations. Modifying procedures that control IQ operations can lead to serious problems.
