SRW.ADD_PARAMETER(myPlist,'SERVER','fooSVR');
SRW.ADD_PARAMETER(myPlist,'CMDKEY','keyvalue');

Integrating with Oracle Advanced Queuing
Additionally, if you have defined an advanced distribution model via a distribution
XML file, you can specify that file with the DESTINATION parameter. For example:
CREATE TRIGGER EXP_REP_TRG
AFTER INSERT OR UPDATE on EXP_REP FOR EACH ROW
myPlist SRW_PARAMLIST;
myIdent SRW.JOB_IDENT;
BEGIN
IF (:new.ExpStat = 'DONE') THEN
myPlist := SRW_PARAMLIST(SRW_PARAMETER('',''));
SRW.ADD_PARAMETER(myPlist,'GATEWAY','http://…');
SRW.ADD_PARAMETER(myPlist,'SERVER','fooSVR');
SRW.ADD_PARAMETER(myPlist,'REPORT','foo.RDF');
SRW.ADD_PARAMETER(myPlist,'USERID','foo/bar');
SRW.ADD_PARAMETER(myPlist,'DISTRIBUTE','YES');
SRW.ADD_PARAMETER(myPlist,'DESTINATION','filename.xml');
SRW.ADD_PARAMETER(myPlist,'ExpenseID',:new.ExpID);
myIdent := SRW.RUN_REPORT(myPlist);
END IF;
END;
This is one way to move this kind of logic from your application into the database and
use the database as a central storage for business processes.
Note: You'll find additional examples of the Event-Driven
Publishing API in action in the demo script srw_test.sql,
included with your OracleAS Reports Services installation.
17.4 Integrating with Oracle Advanced Queuing
Oracle Advanced Queuing is a means for building an asynchronous request/response
mechanism around a so-called queue and two processes: ENQUEUE, which puts
MESSAGES into a queue, and DEQUEUE, which reads the queue.
Advanced queuing provides sophisticated mechanisms for distributing messages
across queues and for queue subscription. These mechanisms are all built on top of
these basic elements (ENQUEUE, DEQUEUE, and MESSAGES).
With the Event-Driven Publishing API you can use these queues to store and transmit
report jobs. You can even build your own queuing mechanism if the one provided
with OracleAS Reports Services does not fit your needs.
17.4.1 Creating a Queue That Holds Messages of Type SRW_PARAMLIST
A queue is a table in the database that holds, along with several administrative
columns, an object column that represents a message. In our case the message is the
parameter list.
The dbms_AQadm package, provided with Advanced Queuing, contains all the
administrative functions required for setting up an advanced queuing system.
