Journaling newbie - questions

[Jeff Crosby <jlcrosby@xxxxxxxxxxxxxxxx>]

All,

I'm just getting started with journaling.  I have a history 
(deficiency?) of not being able to find what I want in the Infocenter.  
There is a ton of reference material in there on journaling, but not 
what I would call a programmer's guide or how-to.  There is a getting 
started list, but it doesn't discuss the whys, only the whats.  And the 
redbook is centered on the performance aspect.

1) Is there anyone out there who is journaling and does NOT have  "HA 
Journal Performance" installed? (On V5R4 it's 5722-ss1 option 41.)

2) I'm looking for a detailed discussion of this:  If I set a journal as 
MNGRCV(*SYSTEM) and DLTRCV(*YES), how specifically does the system 
determine when a journal receiver ("JR") can be deleted?  Once the JR is 
saved somewhere?  A successful save of each and every object being 
journaled?

3) Expansion of #2.  What I have in mind is MNGRCV(*SYSTEM) and 
DLTRCV(*YES), and, a couple of times during the day, save journal 
receivers to tape.  The journal and JR are in the same library and are 
the only objects in that library. (Should they be in separate libs?)  
The ideal would be at a predetermined time do a SAVLIB of the JR library 
which would automajically save any detached receivers and then the 
system "would just know" that JR can be deleted.  Should the *JRN object 
be saved then too?  Shouldn't I be doing a CHGJRN just prior to saving 
the JR?  How does one determine the name of a just detached JR?  How 
does one determine the name of a detached JR if the system did a CHGJRN 
45 minutes earlier?

We do a save of the entire system every day at 12:01am.  What I guess 
I'm looking for is best practices of keeping the database changes (and 
eventually IFS) saved via journaling until the next save.  There is no 
DR or HA site.  I do store tapes offsite as well as onsite.

Thanks.
