Database node
A Database node represents a logical database.
Logical databases no longer modeled by Database Detail nodes in BMC Discovery 11.2 and later
In versions of BMC Discovery before 11.2, Database Detail nodes were used to represent logical databases. In BMC Discovery 11.2, they are now modeled using Database nodes which simplifies the separation of databases from other database details.
Database node lifecycle
The following section describes the scenarios in which a Database node is created, updated or removed.
Creation/update
This is under the full control of patterns and as a result there is no default Database node behavior.
Setting the key for a Database node
The key for a Database node is entirely dependent on the pattern that creates the Database node. You should take care when constructing the key attribute, as it must be unique among all Database nodes. Achieving this uniqueness can be accomplished by including the following information in the key:
- The type attribute
- The parent node's key attribute
Removal
- Manual removal: find the necessary Database node, select it in the list and pick Destroy from the Actions list.
- Authoritative removal by the pattern that creates/updates the Database node should be considered. The pattern needs to create the correct Database structure, and maintain it as the configuration changes.
- Built in removal rules remove all the contained Database nodes if an SI/BAI/Host is removed.
- Built in removal rules remove all the child Database nodes (over both Containment and List) to allow simple deletion of part structures.
Database Attributes
The attributes on a Database node are as described in the following table:
UI Name | Description |
---|---|
Key | Globally unique key. |
Name | Name of the detail. |
Short Name | Short name of the detail. |
Type | Type of the detail. |
Trigger Count | Trigger count. |
Database Relationships
The relationships on a Database node are as described in the following table:
