Oracle SOA Suite XA and RAC Database Configuration Guide
This paper describes the requirements and configuration of Oracle SOA Suite components to provide consistency for global transactions (XA) during operation, including deployments on an Oracle RAC Database 10g. The scope is specific to Oracle SOA Suite and Oracle Application Server interaction and does not cover the broader areas of Oracle SOA Suite enterprise deployment, for which the reader is referred to the Oracle Application Server Enterprise Deployment Guide. This paper describes the steps to properly configure XA for both RAC and non-RAC environments. The required XA configurations are mostly the same for each environment, with only a few differences related to data source and database configuration for RAC instances.
