Hi,

DBMS_JOB is a job scheduler only. It may or may not kickoff jobs that use AQ technology. In Oracle 10g, there is a better scheduler called DBMS_SCHEDULER.

AQ is a queuing technology that is used to asynchronous enque, deque, and propagate messages (the payload).

The “PL/SQL Packages and Types Reference” Manual contains more complete descriptions of both.

Best regards.

Frank

Hi frank,
I got a link in asktom,but unable to understand it,can u pls explain it(don't mind).

---Message Strat Here-------------
Tom,

My question is related with the original question. I made a copy of your
"notifyCB" procedure in my 8.17 environment but when I compiled the procedure ,
it gave me "PLS-00201: identifier 'SYS.AQ$_REG_INFO' must be declared" error.
When I asked my DBA to look into, he replied me back that this object does not
exist in 8i but it exist in 10G.

I neeed to call a pl/sql procedure after a message is enqueued in a queue, how
would I do it in 8.1.7 environment?

Thanks for your help.

Suhail


Followup:
this was a new feature in 9i -- plsql based callbacks.

My environment is 9i,then how can i substitute my dbms_job for submitting the procedure with AQ for submitting the same procedure.

Thanks
Dinesh

Chapter 2 of the same manual explains the callback mechanism:

"CALLBACK - Specifies the action to be performed on message notification.

For e-mail notifications, the form is mailto://xyz@company.com

For AQ PL/SQL Callback, use plsql://<schema>.<procedure>?PR=0 for raw message payload or plsql://<schema>.<procedure>?PR=1 for ADT message payload converted to XML"

Best regards.
