An MQe network can exist independently of MQ, but in many situations the
two products together are needed to meet the application requirements. MQe
can integrate into an existing MQ network with compatibility including the
aspects summarized below:
MQe does not support all the functions of MQ. Apart from environmental,
operating system and communication considerations, these are some of the more
significant differences:
- No clustering support
- No distribution list support
- No grouped or segmented messages
- No load balancing or warm standby capabilities
- No reference message
- No report options
- No shared queue support
- No triggering
- No unit of work support, no XA-coordination
- Different scalability and performance characteristics
However, within MQe many application tasks can be achieved through alternative
means using MQe features, or through the exploitation of subclassing, the
replacement of the supplied classes, or the exploitation of the
rules, interfaces, and other customization features built into the product.
