The DB.LOAD/UNLOAD Utility will return the following error:
U0021528 Owner: '0000000000' of folder: '1234567k\<FOLDER> not found.
The exact numbers in the error will vary from case to case, but this is the general error.
The unload utility performs a folder consistency check during the load/unload procedure and there is one folder that causes the error.
Take the number that is in the place of the above "1234567k" of your specific error and add it to the last line of the following SQL Statement:
select ofs_idnr, o.oh_client, o.oh_otype, o.oh_idnr, o.oh_name as SubFolderName, f.oh_client, f.oh_otype, ofs_level as Parent_ofsl, f.oh_idnr, f.oh_name as ParentFolderName from oh o, ofs, oh f
where o.oh_idnr = ofs_oh_idnr_o
and f.oh_idnr = ofs_oh_idnr_f
and ofs_oh_idnr_f =1234567
Once this statement has been ran, submit the results to Automic Support and reference this knowledge article.
