Default Journaling in V5R4

I created the default journal data area(QDFTJRN) with all the appropriate
upper case entries in my test library and wondered what I needed to do next. I've made
changes to several files and added and deleted records in several files
but nothing shows in my journal.
What starts the "automatic" journal recording?

The following sequence of commands worked OK for me:


 CRTLIB JRNTEST
 CRTDTAARA DTAARA(JRNTEST/QDFTJRN) TYPE(*CHAR) LEN(100)
 CHGDTAARA DTAARA(JRNTEST/QDFTJRN) VALUE('JRNTEST   JRN       *FILE     *ALLOPR')
 CRTJRNRCV JRNRCV(JRNTEST/JRNRCV)
 CRTJRN JRN(JRNTEST/JRN) JRNRCV(JRNTEST/JRNRCV)
 CRTPF FILE(JRNTEST/TESTFILE) RCDLEN(30)
 STRDFU and add a record to JRNTEST/TESTFILE using option 5
 DSPJRN JRN(JRNTEST/JRN)

The DSPJRN command showed the following entries:


 Sequence  Code  Type  Object      Library     Job         Time     
        1   J     PR                           QPADEV0001   4:14:40 
        2   J     XP   TESTFILE    JRNTEST     QPADEV0001   4:14:55 
        3   D     CT   TESTFILE    JRNTEST     QPADEV0001   4:14:55 
        4   D     JF   TESTFILE    JRNTEST     QPADEV0001   4:14:55 
        5   F     JM   TESTFILE    JRNTEST     QPADEV0001   4:14:55 
        6   D     MA   TESTFILE    JRNTEST     QPADEV0001   4:14:55 
        7   F     MC   TESTFILE    JRNTEST     QPADEV0001   4:14:55 
        8   R     PT   TESTFILE    JRNTEST     QPADEV0001   4:15:12

with entry 8 showing my new record:


 Object . . . . . . . :   TESTFILE        Library  . . . . . . :   JRNTEST 
 Member . . . . . . . :   TESTFILE                                         
 Incomplete data  . . :   No              Minimized entry data :   *NONE   
 Sequence . . . . . . :   8                                                
 Code . . . . . . . . :   R  - Operation on specific record                
 Type . . . . . . . . :   PT - Record added                                
                                                                           
             Entry specific data                                           
 Column      *...+....1....+....2....+....3....+....4....+....5            
 00001      'Make it?                      '

I did nothing specific to starting the implicit journaling so you may want to double check your actions with the sequence of commands I used above.

I hope this helps,

The fact that the library already had files in it was not part of the discussion. When I add NEW files everything appears to work just like your example. What a dumb *ss to think it would work with existing files. I’m now pretty sure that the only way to get it to work for all existing files is to back it up and restore it after creating the QDFTJRN.

From the Information Center article Automatically starting journaling:

Using a data area named QDFTJRN, you can automatically start journaling when a non-integrated file system object (data area, data queue, or file) is created, moved, or restored into the library…

I think it would have been helpful if that statement was followed with a clarification that “If the file/object currently exists in the library at the time QDFTJRN is created , no journal action is taken.” Just a thought.

Total agreement. I would suggest sending in a reader comment form on the article making just such a suggestion.
