When MT_DSNUTILB_LOADUNLOAD is set to "yes", this function calls the COBOL program "schema-table-L" for loading data from a file into table in DB, and MT_CTL is not used. The COBOL program is generated by Workbench Rdbms Convertor.

When MT_DSNUTILB_LOADUNLOAD is set to other value than "yes",This function executes a command stored in the file which ddname is MT_CTL.

This command is either an SQLLDR command for Oracle or a DB2 LOAD command for DB2LUW according to the target database.
