ProcedureTo Disable 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 removeSaveStream command. You must specify the following parameters: the plan name and the name of the Save Stream operator. For example:


    [IEP] removeSaveStream test_iep StreamInput0SaveStream0
  3. The Save Stream operator stops saving the input stream to the database table.

    If the Is Global parameter of the addSaveStream command was set to true, then the table and its data are not deleted. However, if you subsequently modify the schema of the stream input (for example, by adding a column) and re-enable the Save Stream operator, then the table and its data are deleted at that time.

    If the Is Global parameter of the addSaveStream command was set to false, then the table and its data are deleted.
