To Enable the Save Stream Operator Dynamically at Runtime

1. Start the IEP monitoring and debugging tool. For detailed information about this tool, see the Open ESB wiki.

2. Run the listIEP command. You must specify the IEP service unit name as a parameter. You can find the service unit name by going to the Services window of the IDE and expanding the Servers node, the GlassFish V2 node, the JBI node, the Service Assemblies node, and the individual service assembly node.

   The command returns a list of plan names. For example:

   [IEP] listIEP CompositeApp1-IepModule1 test_iep

3. Run the listOperators command. You must specify the plan name as a parameter.

   The command returns a list of the operators in the event process. For example:

   [IEP] listOperators test_iep StreamInput0 StreamOutput0

4. Run the addSaveStream command. You must specify the following parameters: the plan name, the name of the Stream Input operator, the JNDI name of the database resource, and the name of the database table where the input stream will be saved. You can optionally specify a boolean parameter called Is Global, which indicates whether the table and its data are kept between deployments. By default, the Is Global parameter is set to true.

   The command returns the name of the Save Stream operator that was added. For example:

   [IEP] addSaveStream test_iep StreamInput0 jdbc/iepseDerbyNonXA STOCKTRANSACTIONS false The result is StreamInput0SaveStream0

5. The Save Stream operator begins saving the input stream to the database table. If the table name that you specified does not exist, then the table is created.
