Destination Attributes (Sun Java System Message Queue 4.1 Technical Overview)

Sun Java System Message Queue 4.1 Technical Overview

Destination Attributes

Attributes set for a physical destination on a clustered broker apply to all instances of that destination in the cluster; however, some limits specified by these attributes apply to the cluster as a whole and others to individual destination instances. This behavior is the same for both clustering models. Table 4–1 lists the attributes you can set for a physical destination and specifies their scope.
