9.5 MQSeries
MQSeries represents a family of products which enable applications to use
message queuing to participate in message-driven processing. With
message-driven processing, applications can communicate across the same or
different platforms, by using the appropriate message queuing software
products. For example, VSE/ESA and OS/400 applications can communicate
through MQSeries for VSE/ESA and MQSeries for OS/400 respectively. With
MQSeries products, all applications use the same kinds of message headers.
Communications protocols are hidden from the application.

Communications protocols are hidden from the application.
MQSeries products implement a common application programming interface, the
message queue interface (MQI), that is used on whatever platform the
applications run. The calls made by the applications and the messages they
exchange are common. This makes it much easier to write and maintain
applications than using traditional methods. It also makes it easier to migrate
message queuing applications from one platform to another.

The current releases on which the following migration discussion is based, are
MQSeries for VSE/ESA Version 1.4 and MQSeries for MVS/ESA Version 1.2.
MQSeries for VSE/ESA Version 1.4 and MQSeries for MVS/ESA Version 1.2.
MQSeries for VSE/ESA 1.4 is a so-called level 1 product whereas the OS/390
version is a level 2 product. Level 2 products offer functions and facilities which
extend those available in level 1 products. Since, generally speaking, level 1
functions are a subset of level 2 functions migration from MQSeries for VSE/ESA
to MQSeries for MVS/ESA can be accomplished without loss of functionality in
most cases.

The topics you should look into if you want to migrate from a VSE/ESA based
MQSeries environment to one based on an OS/390 system include:
MQSeries environment to one based on an OS/390 system include:
•
the setup for MQSeries within your operating system environment
•
the networking definitions required to communicate with other MQSeries
systems
systems
•
the definition of your MQSeries objects such as queues and channels
•
the operating facilities offered to monitor MQSeries activities and diagnose
and fix problems if they occur
