Every node must have a name and may have a comment.
Name assignment is fully validated to assure uniqueness.
Oracle Data Miner generates a default node name. When a new node of particular type is created, its default name is based on the node type, such as "Class Build" for a Classification node. If a node with that name already exists, the name is appended with "1" to make it unique, so if "Class Build" exists the node is named "Class Build 1." If "Class Build 1" exists, then "2" is used so that the third Classification node is named "Class Build 2", and so on. Each node type is handled independently, for example, Filter Columns node to have its own sequence, different from the sequence of Classification nodes.
You can change the default name to any name that satisfies the following requirements:
Node names must be unique within the workflow.
Node names can not contain any / (forward slash) characters.
Node names must be at least one character long; they can not be 31 or more characters long.
To change a node name, either change it in the Details tab of Properties or select the name in the workflow and type the new name.
Comments for the node are optional. If you provide a comments, it must be no more than 4000 characters long.
