RE: Burned by SAVCHGOBJ

SAVCHGOBJ was added to the architecture in the middle of the life of the
System/38.  It could have been in the same release as journaling R04M01, or
later.  It has always had an OBJJRN parameter, and the default was always
no.

Availability was always a problem on the System/38, and journaling was
viewed as an additional availability feature.  Today, journaling is not
really used for availability, with the exception that it provides the
underpinnings for the HA vendors.  Journaling is required for commitment
control and selected rules of referential integrity.

Access path journaling was added in R07M00, and was never highly
implemented.  Today, access path journaling is almost completely replaced
with SMAPP.

Yup...  Last I checked SAVCHGOBJ (looong while back on V4R?) SAVJRNOBJ (or
similar parm) default is *NO.. apparently on assumption You're saving the
journals instead of the objects themselves.  LOTTA
would-a/could-a/should-a's involved, so probably some (multiple) causes
involved in this particular situ.  Meaning SAVCHGOBJ is almost certainly
NOT
to be the root of the problem (although, 'course, there may be VERY RARE
bugs).
