TechTalk: Deleting Internal Journals Saves Disk S

For space management reasons, you need to periodically maintain the internal journals that the AS/400 keeps. The system journals are QAOSDIAJRN (documents), QSNADS (SNADS), QDSNX (Distributed services), and QSXJRN (problem database). These journals should be detached, backed up, and deleted.

This can be done by performing these steps:

1. Detach the current journal receiver and assign a new one for each of the internal journals:

CHGJRN JRN(journal name) JRNRCV(*GEN)

(The JRNRCV parameter value of *GEN will automatically increment the sequence number of the current journal receiver by one, and use it as the new journal receiver name.)

2. Print a list of the currently attached journal receivers for each of the internal journals:

WRKJRNA JRN(journal name)

OUTPUT(*PRINT)

3. Print a list of all journal receivers:

DSPOBJD OBJ(*ALL) OBJTYPE(*JRNRCV) + OUTPUT(*PRINT)

4. Compare the two lists and backup the journal receivers that match (the journal name occurs as the first characters of the journal receiver name) the names of the internal journals and are not currently attached.

5. Delete the journals that were backed up.

For more information see the Backup and Recovery Guide (SC21-8079), Chapter 3.

  • SB HelpSystems ROBOT GenericCan you trust all of your users all of the time? A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
