Bulk loading for DB2 under z/OS requires that several files be created by SAS® software for use by the DB2 LOAD utility. When you do not provide file names, the bulk-load UTILID is generated by SAS using the user ID and the current timestamp to create a unique file name. However, if the user ID is not six bytes in length, the generated name is not built correctly. This behavior might result in the same bulk-load UTILID being generated for two separate steps. When this issue occurs, an error similar to the following is generated:
The workaround is to provide a unique identifier for SAS to use when creating files for the DB2 LOAD UTILID by including the BL_DB2UTID= data set option.
