Morning all,
John & Andrew - you both mentioned that an 'alter table move' would
cause indexes to become unusable. This problem has occurred on a
production database and no apparent cause has been found. There were
around 50 indexes on assorted tables that 'suddenly' went invalid (but
only in DBA_OBJECTS not in DBA_INDEXES where they showed up as VALID and
not UNUSABLE) and none of the tables were moved.
There was a patch applied to the database previous to the problem, but
that had been through testing etc and had not caused invalid indexes
there. It was reapplied to another development database after the
problem was noted and did not cause any problems there either.
In the words of Jim Steinman "Two Out Of Three Ain't Bad" - but in this
case, it is !
Thanks again. I'm still hunting for a cause.
Cheers,
Norman.
