Alex,

Yes, the connection remains open unless it is explicitly closed (see Note: 1034343.6).

The session also takes out a lock on the local RBS (see Note:74811.1) as this could be part of a distributed transaction. If this is a long running query this can lead to abnormal growth in the RBS since the active transaction in the RBS will prevent the RBS from wrapping into that extent. You can avoid this by issuing SET TRANSACTION READ ONLY; prior to running the distributed query.

AFAIK, you can use MTS connections, although I would recommend using dedicated connections for any links used for replication (push and refresh operations).

HTH,
