[Option] /Dumperror code [Description] 
(Optional) Creates the debug dump files, .mdmp and .tmp, when one or more specified events occur while the package is running. The error code argument specifies the type of event code—error, warning, or information—that will trigger the system to create the debug dump files. To specify multiple event codes, separate each error code argument by a semi-colon (;). By default, Integration Services stores the debug dump files in the folder, :\Program Files\Microsoft SQL Server\100\Shared\ErrorDumps. Note Debug dump files may contain sensitive information. Use an access control list (ACL) to restrict access to the files, or copy the files to a folder with restricted access. For example, before you send your debug files to Microsoft support services, we recommended that you remove any sensitive or confidential information. To apply this option to all packages that the dtexec utility runs, add a DumpOnCodes REG_SZ value to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\100\SSIS\Setup\DtsPath registry key. The data value in DumpOnCodes specifies the error code or codes that will trigger the system to create debug dump files. Multiple error codes must be separated by a semi-colon (;). If you add a DumpOnCodes value to the registry key, and use the /Dump option, the system will create debug dump files that are based on both settings.
