Indices will become unusable because of an alter table move. You have
to rebuild the indices immediately after the move. I don't know if the
move online will prevent this or not.

I've seen indexes become "unsable" when an "alter table move ..." is
done and the corresponding indexes are not rebuilt.
select *
from dba_indexes
where status = 'UNUSABLE' order by table_name
Hope this helps.

Even worse, these are DOMAIN indexes not Function Based. But they are
effectively the same as there's a 'package body' (OBJECT TYPE) doing the
'code'.

Now that I could understand as it's nornal behaviour (unless it's a
package BODy being compiled) but we had an export problem with these
indexes previously, the call to get the metadata for the index failed as
the vendor had created it based on the wrong interface - it needed to
use the V2 interface with an OCIEnv parameter. We logged this with the
vendor and received a script to rebuild these index types and recreate
all the indexes.
We have run this and none of the indexes were invalid (nor were the
objects!) - it was one of the things we tested against the test system
to see if we could identify the root cause. Everything was fine - so I'm
still hunting for causes.
Thanks.
Cheers,
Norman.
