The Zeroload function creates the database data files and primes them for use. The database data files contain the segment data and pointers for the database. A database must be Zeroloaded before an application can issue calls against it. An automatic Zeroload is performed by the IMSDBU Load function prior to loading the data. A Zeroload can also be performed by the stand-alone Zeroload utility or DBUTIL.
When running IMSBDU from the command line, the function-id to use for the Zeroload function is ZERO.
