Queues 

Definition

Data elements from an application program are stored for transfer in a queue.

A queue is identified uniquely by a name, which is either defined by the application program or assigned automatically by the queue administration (time stamp) if you do not specify a name explicitly.

The attributes of a queue are determined when the queue is first opened via Queue Attributes.

Integration

Two tables are relevant for internal database administration.

This table is used as a queue directory. Each queue has one table entry, which contains its attributes and administration data.

This table is used as a data pool, in which the actual data objects are stored.
