    Hi

    In my web application, i want to use different databases like oracle, sqlserve and DB2, is it possible with same domanin name or i have to create differnt doman name in the cayenne.xml or i have to create different dataNodes and DataMap files for each database.

    Suppose if creating Muliple DataNodes under single Doman is correct then
    I have to reenginer database and select the appropriate dataNode for each database and datanode configuration with appropriate DB Adapters.
    Do I need any more configuration after doing this ?

    pls let me know.

    I have a sample cayenne.xml file below for Oracle and Sqlserver databases

    <?xml version="1.0" encoding="utf-8"?>
    <domains project-version="1.1">
    <domain name="STESTMultipleDataBase">
            <map name="STESTOracleMap" location="STESTMap.map.xml"/>
            <map name="STESTMapSqlserver" location="STESTMapSqlserver.map.xml"/>

            <node name="STESTOracleNode"
                     datasource="jdbc/EDWDORACLE"
                     adapter="org.objectstyle.cayenne.dba.oracle.OracleAdapter"
                     factory="org.objectstyle.cayenne.conf.JNDIDataSourceFactory">
                            <map-ref name="STESTOracleMap"/>
             </node>
            <node name="STESTSqlServerNode"
                     datasource="jdbc/EDWDSQLSERVER"
                     adapter="org.objectstyle.cayenne.dba.sqlserver.SQLServerAdapter"
                     factory="org.objectstyle.cayenne.conf.JNDIDataSourceFactory">
                            <map-ref name="STESTMapSqlserver"/>
             </node>
    </domain>
    </domains>

    Thanks
