JDBC Connection Options Summary

There are several ways to define CA Datacom Server connection information. Commonly used options are as follows:

When using the JDBC driver with a Servlet, EJB, or other application running an application server, all information can be defined in a DatacomDataSource, or more likely, a DatacomConnectionPoolDataSource object, and accessed using the container's JNDI implementation. It is not necessary to define an ODBC style data source.
When using the JDBC driver in a stand-alone Java application on Windows or z/OS, a JNDI implementation is generally not available, and it is usually convenient to reference an ODBC style data source in a CA Datacom URL, accessed using the DriverManager. The ODBC style data source is defined in the registry on Windows and the configuration file on the mainframe.
When using the JDBC driver in an applet or stand-alone application that connects using the JDBC Proxy, it is usually most convenient to reference an ODBC style data source defined on the machine where the JDBC Proxy invokes the native client interface.
