The DB2 colleague told me that the target db uses the IBM500 codepage. but If I use this in the job property, the job won't read any lines from the text file, because it can not find the delimeter in the file. So I can not use this code page.
No, the delimeter is comma. If I use the normal code page, like ISO-8859, utf-8, windows-1252, then the same job will run without error, but the character appears like I mentioned, not as I'd like to have.
