We have installed Nuxeo DM 5.6 on Tomcat server, which uses Oracle database. Default repository configuration template (templates/common-base/nxserver/config/default-repository-config.xml.nxftl) specifies for Oracle (and for the other database types as well) an xa-datasource: oracle.jdbc.xa.client.OracleXADataSource.

To avoid the performance overhead of xa transactions for database calls we want to use a non-xa datasource. Is there a way to configure a non-xa datasource (e.g. local-tx-datasource) on Tomcat? How could we do that?

Thank you, Dorin
