Queues hold work items that are waiting to be processed.
You can manage user queues and create work queues and component queues.
Workflow queues
Workflow queues hold work items that are waiting to be
processed.
Creating work queues
Work queues hold work items that can be completed by more
than one user or can be completed by an automated process.
Component queues
Component queues make it possible to process a workflow
step by using an external entity, such as a Java™ object or Java Message
Service (JMS).
Creating workflow rosters
A workflow roster is a database structure that stores information
about all workflows in an isolated region. Workflow rosters provide
the workflow system and workflow administrators with an efficient
way to locate specific active workflows.
