Afternoon all,
Sorry about the 'stupidity' of the following question, but I've just
been bitten by it, and I can't find a proper answer anywhere in the
Oracle DOCS, online or anywhere. If you know of a location for a Fine
Manual that I can read, please tell me. Thanks.
I have a database which calls out to an external software package via
an extproc listener. This started failing for no apparent reason with
'failed to verify indextype' errors.
DBA_INDEXTYPES has no STATUIS columns, but joining to DBA_OBJKECST gave
me 'VALID' for the STATUS column there.
Looking at all my indexes under DBA_INDEXES shows the STATUS to be
VALID there as well.
As far as I was concerned, the error was misleading - my indexes and
indextypes are ok. (First mistake !)
However, further investigation (after raisng a call with the vendor)
showed that under DBA_OBJECTS, for some of the indexes, the STATUS
column showed up as INVALID. This was the cause of my problem.
Q1. How is it possible for an INDEX to be VALID but the object to be
INVALID ?
Q2. Is it wrong of me to think that if the object is 'broken' that the
index should be too?
I've looked in the docs, the status column on XXX_INDEXES says that it
is for unpartitioned indexes and shows whether they are valid or
unusable. For the XXX_OBJECTS the status column simply says where 'the
object is valid or not'.
What am I missing ?
Cheers,
Norman.
