New features for Multiplatforms

IBM MQ 9.0 publishes information messages to a range of system level topic strings. An authorized user can subscribe to these topics to receive monitoring information for the queue manager and application activity on it.

Performance monitoring API

In IBM MQ 9.0, statistics are published to a system topic under $SYS/MQ/INFO/QMGR that help users monitor resources.

These statistics can be viewed by running the amqsrua sample, or by writing an application that subscribes to the resource monitoring system topic in a similar way to amqsrua. For more information see Monitoring system resource usage by using the amqsrua command and Developing your own resource monitoring program.

Enhanced application activity trace

Application activity trace produces detailed information about the behavior of applications that are connected to a queue manager. IBM MQ 9.0 adds the ability to dynamically subscribe to this information rather than collecting the information through queue manager level configuration. For more information, see Subscribing to application activity trace information.

You can use the following keys:

• Use the up arrow key to recall the previous runmqsc command
• Use the down arrow key to recall the next runmqsc command
• Use the tab key to offer completion options for the next keyword in the command

For more information, see The runmqsc command line editor on UNIX.
