Two Contexts for Developing Queuing Applications

Oracle AQ offers two development contexts:

• Native AQ which can be accessed by means of three different programmatic environments
  • from PL/SQL using the DBMS_AQ/AQADM PL/SQL Packages (see also Oracle8i Supplied PL/SQL Packages Reference )

  • Visual Basic using Oracle Objects for OLE (OO4O) (see also Online Help for Oracle Objects for OLE)

  • Java using the oracle.AQ Java Package (see also Oracle8i Supplied Java Packages Reference ).

We discuss working in this context in Chapters 1-11.

• Java Messenging Service (JMS)
  • Java using the oracle.jms Java Package. This implementation of a public standard extends the defined W3C interfaces so that developers operating in the JMS context have the same means as those working within Native AQ.

We discuss working in this context in Chapters 12-16. For more information on the oracle.jms Package, see the Oracle8i Supplied Java Packages Reference .

As discussed in the following section, each of these contexts has different terms for the same functionality.
