Visit IBM Redbooks, download and read MQSeries Backup and Recovery. Next, I'd suggest reading the Recovery and Restart section of the WMQ System Administration manual.
The record mq object and recover mq image control commands have some use for recording and recovering mq object images to the logs; but if your logs are damaged or lost, you have nothing to recover from.

Thanks for the help I did made some recovery steps using the MQSereis Backup/Restore IBM Book. Is it ok? Please check it.
Recovery of a Queue Manager:
To restore a queue manager:
(a) Stop all channels.
(b) Shut down the queue manger.
(c) Archive the current logs.
(d) Restore the queue manager files
(e) Restart the queue manager.
(f) Start the channels.
(g) If necessary, re-synchronize the channels.
Recovery of a Queue
Prerequisites:
The queue manager must be running.
Example:
Recover the queue “ORANGE!QUEUE” of queue manager “venus!queue!manager” using media recovery:
rcrmqobj -m venus!queue!manager -t q ORANGE!QUEUE
Error Code: AMQ8149
If you get the message ″AMQ8149 MQSeries object damaged″, perform a media recovery for this object.
The command rcrmqobj is used to re-create application or system queues.
Prerequisites:
1. Queue Manager must be running.
2. An image has been recorded in the log.
For example:
• Media recovery of all queues of the queue manager venus!queue!manager:
rcrmqobj -m venus!queue!manager -t q SYST*
rcrmqobj -m venus!queue!manager -t q venus!queue!manager*
• Media recovery all local queues of queue manager venus!queue!manager:
rcrmqobj -m venus!queue!manager -t ql venus!queue!manager*
• Media recovery of all remote queues of queue manager venus!queue!manager:
rcrmqobj -m venus!queue!manager -t qr venus!queue!manager*
• Media recovery of all alias queues of queue manager venus!queue!manager:
rcrmqobj -m venus!queue!manager -t qa venus!queue!manager*
• Media recovery of all model queues of the queue manager venus!queue!manager:
rcrmqobj -m MQ61 -t qm MQ61*
Recovery of synchronization file
Instructions:
The command rcrmqobj is used to re-create the channel synchronization file.
Prerequisites:
This command must be used when the queue manager is running and after an image was recorded in the log.
Example
Recover the channel synchronization file:
rcrmqobj -m QM_NAME -t syncfile amqrsyna.dat
Error Code AMQ9556
If you get the message ″AMQ9556 Channel synchronization file missing or damaged″, perform a media recovery for this system file.
1. Stop all channels.
2. End the queue manager.
3. Restart the queue manager.
4. Perform media recovery with the command:
rcrmqobj -m QM_NAME -t syncfile amqrsyna.dat
5.Start the channels. |

What is your objective? What type of recovery are you trying to accomplish?
Some things to think about:
If you have a physically damaged disk, then you must recover (reinstall) the o/s, wmq software, your object definitions.
If the mq filepath becomes damaged, these control commands will likely not help you because control commands execute on a healthy qmgr with good logs.

Following points to be consider for recovery:
The Queue manager is Linear type.
1.Disk Drive Failures
After reinstalling the OS
And using the last point in time recovery backup the queue manager data. And then using the rcrmqobj to recover the objects and massages..(keeping mind that there would be some massages which are not recoverable).
2.Damaged Queue Manager object.
Using the media recovery..
3.Damaged single object
Using the Media recovery. |

What do you intend to use as the "last point in time recovery backup the queue manager data?" What and how are you going to backup "queue manager data?"
Your queue manager(s) are contained in sub-folders down the WMQ filepath. This is documented in the System Admin manual.
