You can define temporary attributes in the types.cf file. The values of temporary attributes remain in memory as long as the VCS engine (HAD) is running. Values of temporary attributes are not available when HAD is restarted. These attribute values are not stored in the main.cf file.

You cannot convert temporary attributes to permanent attributes and vice-versa. When you save a configuration, VCS saves temporary attributes and their default values in the file types.cf.

The scope of these attributes can be local to a node or global across all nodes in the cluster. You can define local attributes even when the node is not part of a cluster.

You can define and modify these attributes only while VCS is running.
