We are having an internal debate to reuse deleted records or not. The--
most recent info I can find on the subject dates back to V5R4, we are
Here are a few of the issues that I am aware of REUSEDLT(*YES) will...
- Cause arrival sequence processing to require attention.
- SQL cursors without an ORDER BY will give data in seemingly
random order according to the SQE's implementation of the request
(don't ask how we were bit by this :))
- May cause problems concerning access path maintenance, thus
potentially impacting performance (as of V5R4, this did not appear to
be an issue any longer?).
- Modernizing the DB to DDL (from DDS) will result in tables that
are REUSEDLT(*YES) by default as the CREATE TABLE SQL does not have
provision for restricting deleted row reuse.
- Does not completely exclude the need for periodic RGZPFM to be
run on the tables.
The question is... with enhancements to the SQE in V7R1 and
REUSEDLT(*YES) provide a significant lessening of the need for RGZPFM
(perhaps annually or monthly versus weekly on select tables) without a
performance problem over time?
