Deleting Resources
EPICenter Software Installation and User Guide 213
Deleting Resources
The Destroy button in the Grouping Manager toolbar lets you delete user-defined resources from the
EPICenter database. The destroy function removes the resource from the database entirely, removing it
from all groups where it exists as a child.
NOTE
You can only destroy resources whose source is “Manual” (except for the predefined groups) and the
root groups of imported resources. You cannot destroy the predefined groups, system-defined resources
(devices, device groups, or ports) whose source is EPICenter, or individual imported resources (where
the source is a file, LDAP database etc.). If you select a resource you cannot delete, the Destroy button
will not be available.
To delete a user-defined resource do the following:
1 Select the resource in the Component Tree.
2 Click the Destroy button on the toolbar.
A confirmation dialog will be displayed. Click OK to confirm that you want to delete this resource.
If you delete a group, any orphaned children of the group (resources that are not members of any other
group) are also deleted.
If you delete a Host or User, all relationships to other resources are also deleted.
To remove a resource as a child of a group, use the Remove function, see “Removing A Child Resource
from a Group,” on page 216. This just removes the parent-child relationship with the group, but does
not delete the resource from the database.
Adding a Resource as a Child of a Group
NOTE
You cannot add Resources as a Child of a Group for Custom Applications.
A group’s children are individual resources or subordinate groups that will be manipulated or managed
together. A resource is placed into a group as it is created— either the root-level group, or the group
that was selected when it was created. However, because a resource can be a member of multiple
groups, you may wish to add an existing resource to an additional group, or move it to a different
group. To add a resource to a group, you select the resource from a list of the resources that are
currently defined in the EPICenter database.
You can add individual resources as children of a group, or you can add groups as children. You cannot
add an ancestor group as a child of one of its subordinate groups. You cannot have subordinate groups
of Applications below the Custom Applications group.
When you add a group as a child of another group, all members of the sub-group (its children) are
considered members of the higher level (ancestor) group. As membership in the sub-group changes, so
does the membership in the higher level (ancestor) group. This can have important effects when a
group is used by another EPICenter module. For example, suppose you create group “A” that contains
