Locking Nodes
To prevent other users from amending the settings of one or more nodes in a stream, you can
encapsulate the node or no des in a special type of node c alled a SuperNode, and then lock the
SuperNode by applying password protection.
Working with Streams
Once you have connected source, process, and terminal nodes on the stream canvas, you h ave
created a stream. As a collection of nodes, streams can be saved, annotated, and adde d to projects.
You can also set numerous o ptions for streams, suc h as optimization, date and time settings,
parameters, and scripts. These properties ar e discussed in the topics t ha t follow.
In IBM® SP SS® Modeler, you can use and modify more than one data stream in the same

helps you to navigate the streams, outputs and m odels th at are currently open. If you cannot see
the managers pane, c lick Managers on the View menu, then c lick the Streams tab.
