Advanced Queuing - Oracle

The following command shuts down the Messaging Gateway agent:
SQL> exec dbms_mgwadm.shutdown
Working with Messaging Gateway
When Messaging Gateway completes the shutdown procedure, the AGENT_STATUS
column indicates NOT_STARTED.
By monitoring the MGW_GATEWAY view and the log file, you can determine the
success of the shutdown procedure. If problems occur during shutdown or
unexpected events occur that leave the Messaging Gateway administration in an
inconsistent state, you can reset status information, as follows:
SQL> exec dbms_mgwadm.cleanup_gateway(dbms_gmwadm.CLEAN_STARTUP_STATE)
The Messaging Gateway agent process must not be running when this command is
executed.
Configuring Messaging Gateway Links
You can use SQL scripts to configure Messaging Gateway, as illustrated in the
following script examples. Full examples are found in the samples directory of the
Messaging Gateway installation.
Creating a Messaging Gateway Link
A Messaging Gateway link is a set of connection information to a non-Oracle
messaging system. It is used whenever a connection is needed for either messaging
or administrative work.
You can set the following information for a link to an MQSeries queue manager: the
queue manager name, channel, host, port, username, and password for an
MQSeries client connection. Log queues for inbound or outbound propagation must
also be set for use by the Messaging Gateway agent in guaranteeing exactly-once
delivery. The two queues can refer to the same physical queue, but better
performance is achieved if they refer to different physical queues.
An options argument, a set of {name, value} pairs, both of which are strings,
represents arguments specific to a non-Oracle messaging system interface. For
MQSeries-recognized property names, these include:
‘MQ_ccsid’ for the corresponding MQEnvironment.CCSID property
‘MQ_SendExit’ for MQEnvironment.SEND_EXIT
‘MQ_ReceiveExit’ for MQEnvironment.RECEIVE_EXIT
