Symptoms
By default every Oracle database gateway starts a dedicated transaction as soon as it connects to the foreign database. So even when you are just selecting data then locking of the remote tables might take place.
Changes
Starting with 11.1.0.6 a couple of fixes were released <Bug:7417128> and <Bug:8204019> that introduced new gateway parameters impacting the locking mechanism of the gateway.
