IBM MQ Series, now known simply as IBM MQ, is a messaging middleware that allows applications to communicate with each other. Administration of IBM MQ involves using various commands to manage queues, topics, channels, and other aspects of the messaging system. Here are some of the main IBM MQ administration commands:

1. Display Queue Manager Information: dspmqinf
2. Create Queue Manage: crtmqm
3. Start Queue Manager: strmqm <QueueManagerName>
4. Stop Queue Manager: endmqm <QueueManagerName>
5. Display List of Queue Managers: dspmq
6. Display Queues: dspmq -m <QueueManagerName>
7. Create Local Queue: runmqsc <QueueManagerName> Inside the runmqsc console: define qlocal(<QueueName>) end
8. Create Remote Queue: runmqsc <QueueManagerName> Inside the runmqsc console:define qremote(<QueueName>) RNAME('<RemoteQueueManager>') XMITQ('<TransmissionQueue>') end
9. Display Channels: dis chl(<ChannelName>)
10. Start Channel: start chl(<ChannelName>)
11. Stop Channel: stop chl(<ChannelName>)
12. Display Listeners: dis listener(<ListenerName>)
13. Start Listener: start listener(<ListenerName>)
14. Stop Listener: stop listener(<ListenerName>)
15. Display Topic Information: dis topic(<TopicName>)
16. Create Topic Object: runmqsc <QueueManagerName> Inside the runmqsc console: define topic(<TopicName>) topicstr('<TopicString>') end

These commands are a subset of the many commands available for IBM MQ administration. Always refer to the official IBM MQ documentation for the most up-to-date and comprehensive information on IBM MQ administration commands and practices.
