Enforce uniqueness for device group names

The option Unique Device Groups allows you to control the uniqueness of device group names across all device nodes.

• If you enable uniqueness checking, all device groups on a server node are considered one list across the namespace. And because device group names are not case sensitive, a specific name is allowed only one time, regardless of case.

• If you disable uniqueness checking, you can have the same device group name in different device nodes, but not in the same node (inside device groups, names are not case sensitive). This means that device group names are unique on one hierarchy level only.

By default, Unique Device Groups is selected. Checking for uniqueness is required when working with DDE/SuiteLink installations.

Enforce uniqueness for device group names

1. In the OI Server Manager, navigate to the Configuration node.

   1. Expand the Operations Integration Server Manager node, expand the node group, and then expand Local.

   2. Expand the Communication Driver, and then select Configuration.

   The Global Parameters tab appears in the details pane.

2. In the Enable/Disable area, the Unique Device Group check box is selected by default as it is required for working with DDE/SuiteLink legacy installations. If you clear this check box, device group names must be unique on one hierarchy level only.

3. Select Save.
