The following issues must be considered when using an Oracle replicate data server:
In ECDA Option for Oracle version 12.0 or later, an additional trace flag allows the replicate Replication Server to control transaction commit boundaries when applying transactions to an Oracle replicate database.
Setting the value of the ECDA autocommit trace flag to 0 (zero) in the ECDA Option for Oracle configuration file allows Replication Server to control when a COMMIT command should be sent to Oracle. When the value of the autocommit trace flag is not set, ECDA Option for Oracle commits each individual operation (INSERT, UPDATE, and DELETE) sent by the replicate Replication Server.
Having ECDA commit each operation causes a problem at the replicate database if an error occurs in the middle of a multiple operation transaction. The replicate Replication Server may attempt to re-send the entire transaction, while ECDA has already committed each individual operation. To avoid this problem, set the value of the ECDA autocommit trace flag to 0 (zero).
