Another aspect of table I/O has
to do with situations in which a query requests access to a table
or fragment in a dbspace that is temporarily unavailable. When the
database server determines that a dbspace is unavailable as the
result of a disk failure, queries directed to that dbspace fail
by default. The database server allows you to specify dbspaces that,
when unavailable, can be skipped by queries, as described in DATASKIP.
Warning:
If a dbspace containing data that a query requests is
listed in DATASKIP and is currently unavailable
because of a disk failure, the data that the database server returns
to the query can be inconsistent with the actual contents of the
database.
