Since I'm not sure whether this is an RPG problem or a lack of understanding
about receiving journal entries with RCVJRNE, I'm not sure where to post
this, so i'm posting to both Midrange-L and RPG400-L.
My system is on V5R1.
I'm experimenting with using RCVJRNE to process the 'CO' journal entries
from the system audit journal (QAUDJRN). The goal: I want to detect when a
file gets created in the IFS.
For this test, the stream file I created was '/home/SJL/source16.txt'
As usual, the IBM documentation is about as clear as mud and stored in
several different places (B&R guide, Security Guide, etc.). I'm about to
pull my hair out (if you know me, that's funny because you know how much
hair I have left...).
I used some sample code that I received from another member (thanks,
Carsten) to construct this program. However, it was for file journal
entries, *not* 'CO' entries. I *thought* (there I go, thinking again) that
I could just use the system-supplied outfile for *TYPE4 entries in my
program as the receiver (parameter 1) for these entries, since it matches
the layout of the buffer described in the above-mentioned guides.
However, it appears that things aren't mapped properly into this buffer
area. Everything beyond the system name (COSYNM) seems to be improperly
mapped.
Are the variable-length fields hosing me up?
In the field named CORESA (see below),
I see this value: '00000811N*N *N *STMF '.
The 00000811 probably should have been mapped to the field COESDL
(Entry-specific data length). The First 'N' should have been mapped to
COETYP (Type of Entry). The first '*N' should have been mapped to COONAM
(Object Name), the second '*N' should have been mapped to COOLIB (Library
Name), and the value '*STMF' should have been mapped to COOTYP (Object
Type)....and so on.
When I run the RPG program in debug, here is what the DSType4 data structure
looks like for the 'CO' journal corresponding to the creation of this file:
COENTL OF DSTYPE4 = 00990.
COSEQN OF DSTYPE4 = 0001918049.
