Websphere mq application programming guide

It enables an Oracle application to communicate with the Oracle integrating server, and it enables the Oracle integrating server to communicate with the gateway. A programming call that invokes a program on a system in response to a request from another system. Queued messages can be stored at intermediate nodes until the system is ready to forward them to the next node. As used in this guide, the production server refers to any Oracle server that you use for production, for actual business and not for testing.

The Oracle integrating server communicates with a gateway in the normal Oracle server-to-server manner using Oracle Net. With WebSphere MQ messaging, two or more applications communicate with each other indirectly and asynchronously using message queues.

For example, a sending application can specify that queued messages should survive system crashes. WebSphere MQ is a message queuing system based on the model of message queue clients and message queue servers. Any Oracle server that communicates with the gateway.

Support for IBM WebSphere MQ

If you do not want to set up static conversion exit routines, you can let SAS convert the data for you as an alternative solution. Client applications need not be on a specific operating system. The gateway integrates with existing WebSphere MQ applications without any changes to those applications and enables users to exploit their investment in these applications while providing them with the ability to maximize on the benefits of message-oriented systems.

The gateway does not require any Oracle software on the remote system. Oracle applications do not connect directly to the gateway, but connect indirectly through an Oracle integrating server. Queue manager A WebSphere MQ feature that provides the message queuing facilities that applications use.

This leads to a higher level of availability for the participating applications. These procedures resemble the calls and types of MQI, but they are adapted to take full advantage of the transaction integration with the Oracle integrating server. It has no background processes webaphere does not require a programing utility such as Oracle Enterprise Manager.

If the message is not comprised entirely of character data, you will have to create a conversion exit.

These resources are associated with message options and descriptors. The following components are included: Using the MIPs generated by the Visual Workbench, you can use the gateway to interface with the existing procedural logic or to integrate new procedural logic into an Oracle progeamming server environment.

A WebSphere MQ feature that provides the message queuing facilities that applications use. The MIP provides the underlying code to interact with the gateway, performs message data conversion, and provides an easy-to-use interface for Oracle applications to exchange messages with remote WebSphere MQ applications.

Data conversion of this user portion can be handled by either WebSphere MQ conversion exit routines or by SAS using data mapping control.

WebSphere MQ server configuration A WebSphere MQ configuration where the queue manager and message queues are located on the same local system or node as the application software. Oracle integrating server Any Oracle server that communicates with the gateway. The applications send or receive messages through a queue by sending a request to the message queuing system. This provides for a reliable communication channel between applications. For more information about these procedures, refer to Appendix A.

Flexible interface Using the MIPs generated by the Visual Workbench, you can use the gateway to interface with the existing protramming logic or to integrate new procedural logic into an Oracle integrating server environment. The applications run either on the server node where the queue manager and queues reside, or on a remote client node.

Each Oracle integrating server user session that accesses a gateway creates an independent process on the host system that runs the gateway.

The integration of the Oracle integrating server with ms gateway enables you to benefit from existing and future Oracle features. Storage areas for messages exchanged between applications. Next, the program must open the desired queue before it can use it.

This generated code is called the message interface package MIP. On UNIX platforms, a gateway process is started for each user session. As another example, the receiving application can specify a maximum waiting period for a receiving operation from a queue in case no messages are available yet on the receiving queue.

An application wishing to communicate with another application simply sends a message to a queue. For example, a trigger could cause an Oracle application to call the gateway to retrieve a WebSphere MQ message and process it.
