In library QRECOVERY, I see files QDBJRN0457 QDBJRN0458, QDBJRN0459 and QDBJRN. The first 3 files appear to be backups. They are very large. May I delete these files? Will there be an impact?

These sequencial numbers items should be journal receivers

You should back them up before deleting them.

Journal receivers contain a history of changes to tthe jorunaled physical files or access paths and can be used to recover data.

If QDBJRN is also a receiver, the same rules apply but if it’s the “journal” do not delete it.

The journal contains the rules for journaling not the data.

==========================================================

If you are at V5R2 or later, these might be okay to delete; otherwise, no, these should <b>not</b> be deleted and you might not be allowed to delete them. One related example quote from the V5R4 Info Center : “You should not use the library <b>QRECOVERY</b> because it is intended for system use only. The library <b>QRECOVERY</b> contains objects that the system needs to operate properly.”

The name alone should warn you off when you’re not <i>certain</i> about the consequences.

In this case, none of the objects are “files” nor are they “backups”. QDBJRN was a journal for the system database cross-reference files. I <i>think</i> QDBJRN is not used after V5R1.

    These Journal Recievers can eat up storage. And yes they should be backed up before deleting them. Jack
