JCL utilities:
If you have used the spool archiving utility, MVSSPLHK, to perform a FULL archive prior to Enterprise Developer 3.0 HF4, the archive may have failed to write records to the archive catalog. It may be missing the required information to display spool files, and a 'File not Found' error will be reported on the ESMAC page when clicking on a spool file entry. If that is the case, a utility to correct the errors, and insert the correct catalog records is available through your Micro Focus Customer Care engineer.
Archive files created using Enterprise Developer 3.0 HF4 and later are working correctly.
