Re: Journal receivers



fixed

I presented insufficient information. I thoughht the question was so
common that details would have been tedious.


from WRKJRNRCV:
Journal: QDBJRNXRFQ
Receiver: QDBJXQ0001
Attach date: 07/12/06
Size (K): 286884

No detach or save date.

from WRKJRNA:
Manage receivers: *SYSTEM
Delete receivers: *YES

What drew my attention was that the journal receiver was 0001.

Something is odd. Is there a system value that is potentially wrong?

Thanks,

John McKee

Looking at other journal receivers, I see a few large ones in
QRECOVERY. Specifically, QDBJxxxxxx and QSQJRN0391. Biggest is
QDBJXQ0001.


I do not recall specifically the latter naming, but I am almost sure I
recall what the associated journal is for; the *DBXREF queue (QDBXREFQ*
x/0AC4) journaling. With the associated Journal (*JRN) name, finding [if
there is any] more specific documentation\information would be easiest.

Is there a process that is supposed to be run to detach these
receivers, or is that just done manually?


Each journal environment for which those [system] receivers are
established, should include the Manage Receivers (MNGRCV) setting of
*SYSTEM and the Delete Receivers (DLTRCV) setting of *YES; refer to the
Work With Journal Attributes for the *JRN associated with each of the
noted\named Journal Receiver (*JRNRCV) objects. Thus there should be only
one journal receiver object that is active\attached per journal object.
The maximum size of the journal receiver before deletion will be
determined by the Receiver Size Options of the journal and the Threshold
attribute of the journal receiver; see the Display Journal Receiver
Attributes (DSPJRNA) for the threshold and the associated Journal object.

Note that the QRECOVERY library is omitted from the Backup phase of B&R
[thus effectively, the origin for the system library name prefix paired
with the word "RECOVERY"].

With the default journal environment, the request to Change Journal
(CHGJRN) to request attaching a new generated-name or an explicitly named
journal receiver will enable reducing the current storage for a[n at least
partially] full receiver to the storage of an empty receiver. For example,
the request to CHGJRN QSYS2/QSQJRN JRNRCV(*GEN) would effect a new empty
receiver with the next receiver name and the previously attached receiver
would be detached and deleted. Of course, over time, the receiver will
again fill-up approaching the maximum allowed size before system-managed
change to a new receiver. Although the journaling environments could be
customized [from the defaults], normally that would only be done to enable
problem investigation or to circumvent a problem with any negative effects
per the defaults.
