Change in functionality in this version of ECDA Option for Oracle.
ECDA for Oracle no longer ships with Oracle Client libraries. Obtain the Oracle Instant Client libraries from the Oracle Web site at http://www.oracle.com.
The Oracle Instant Client libraries do not contain XA functionality; therefore, DirectConnect for Oracle (DCO) no longer supports two-phased commit functionality. When the two_phase_commit option is set to 1, a message indicates that the feature has been deprecated.
