MQSeries Protocol

This section describes how you can submit requests to ITP/Server over MQSeries message queues.

For every job that you want to submit you should at least perform the following steps:

1. Connect to the queue manager that manages the request queue.
2. Open the request queue for output.
3. Put one or more request messages on the request queue. Each message specifies a single request.
4. Close the request queue.
5. Disconnect from the queue manager.

This protocol allows you to submit several jobs over a single queue. In fact, the same queue can be used simultaneously by a number of clients. The steps above only describe the most basic form of interaction with ITP/Server via MQSeries. More complex forms of interaction are described below.

How you connect, open a queue, send a request, close a queue and disconnect is described in the MQSeries manuals. This section describes the format of the requests that you sent to ITP/Server.

Note that any client that has the MQSeries middleware installed can send requests to ITP/Server (provided it has sufficient access rights). Currently the MQSeries client software is available for:

• AIX
• AT&T GIS UNIX (this platform has become NCR UNIX)
• Digital OpenVMS
• DOS
• HP-UX
• OS/2
• SINIX and DC/OSx
• Sun Solaris
• VM/ESA
• Windows 3.1
• Windows 95, Windows 98 and Windows ME
• Windows NT, Windows 2000, Windows XP and Windows 2003
