Embodiments of the present invention generally provide a system, method
and article of manufacture for managing federated queries. In general,
the availability of one or more databases targeted by a federated query
may be determined prior to running the federated query against the
targeted databases. In response to determining one or more of the
targeted databases are unavailable, a user may be notified. The user may
also be presented with options for running the federated query. The
options may include being notified when all of the targeted databases are
available, automatically running the federated query (in the background)
when all of the targeted databases are available, and modifying the query
to run against currently available databases.
