Re: RPGLE I/O opcodes with commit/rollback

IDK about 'code' examples but the Godfather of Journalling would be Larry
Youngren of IBM. He regularly speaks at COMMON, writes articles for
iprodeveloper, redbooks, etc.
Things to consider include
- Whether to journal file open/closes
- Keep before/after images in your journal?
- For "Minimize entry specific data (MINENTDTA)" on CRTJRN which option
should I pick?
- How often to do commit cycles? For example, committing after 1 on
screen transaction (which may update a number of 'child' files) may make
sense. But do you really want to a "update 2billionrowtable ..." without
committing a few times in there?
and the list goes on.
