Delete Attribute

Use this command to delete an Attribute.

An attribute is data used to describe the characteristics of an object in Longview. For example, SWFAdminEMail is an Attribute representing the email address of an Administrator.

This command must be used in conjunction with Maintenance. While it is enabled, no other users can perform maintenance related activities in the Data Server repository. When you are finished, you must remember to disable the Maintenance mode, and thereby allow normal access by other users. For more information, see Maintenance or Exclusive.
