Hi All,
I already created Queue Manager but I am not providing -ll (Linear Logging) so it takes default option as circular logging.
Created all objects for queue manager what are required for me.
Now I want to take media backup and media recovery.
rcdmqing - m SS - t queue SL
Then i got error "media recovery not allowed"
If it comes error then always I can create new queue manager.
Is there any possible to alter queue manager or other solution for this.
Thanks,
Suresh K |

Hello,
To use the recovery image commands , you should have activated the linear logging functions.
This functional option is required mainly to ensure continuity of the recovery images written on the logs by the recovery objects commands to the last checkpoint ,that may be instead incomplete in case of circular logging ...
Hope it helps . |

Hi MQsysprog,
I know To use the recovery image commands , you should have activated the linear logging functions. i.e when creating queue manager provide -ll for queue manager.
I forgot to give -ll option for Queue Manager.But I want to media recovery and media backup .
rcdmqimg - m SS - t queue SL
Then i got error "media recovery not allowed"
Is there any possible to alter queue manager or other solution for this.
Thanks,

Hi
The linear or circular logging is a initialization option of your Qmanager ,so to obtain the media recovery functions you must do a controlled shutdown ,and then a restart with the activation of linear logging .
Here you could find some useful informations :

@MB Developer, the rcdmqimg command will NOT work with circular logging, no matter what you try, period! You will need to delete and redefine your queue manager with linear logging.

This is a meaningless, and totally misleading, statement, which if you'd read the content of the link you posted you would have known not to post, i.e. "...Note: The LogType attributes, circular or linear, cannot be changed once the queue manager has been created...".

Hi Suresh,
if i remeber well there was a specifical redbook on these particular functions ,with the title '' MQ recovery and restart'' or something
like this ...
I would suggest you a search on the net to find a copy of this book ,probably it is a bit old ,but anyway useful .
I have on my shelf a printed copy of it at hand .
Ciao

Hi,
The redbook on MQ Backup and Recovery is available here :
http://www.redbooks.ibm.com/redbooks/pdfs/sg245222.pdf
And forgive my previous error already pinpointed by exerk ,
obviously the logging mode of the Qmgr is a main initialization
parameter that requires a new creation of the Qmanager itself... |

Suresh,
If you are going to rebuild your Qmgr to switch to linear logs, also consider changing your log file pages. If you have not calculated what this number should be and have no info to work with, pick 16384. This is the other Qmgr attribute you cannot change after creation.
Search this forum for qm.ini stanzas and you will find other useful information a newbe will not normally find (until you have a problem). |

Depending on your WMQ version, most settings are in the Windows Registry.

Use MQExplorer to change the number of logs - I strongly advise not to do it by changing the Registry values directly - as regards the size, that's fixed at creation time and can only be changed by deleting/redefining the queue manager.

Hi exerk,
Using MQExplorer I can change log files for Queue Manager DL1 but when I want to show these files into "C:\Program Files (x86)\IBM\WebSphere MQ\log\DL1\active" path log files are not effected.
Before I can change log files are in Queue Manager is 3
I can increasing to log primary files to 5 but in queue manager log path it show only 3 files.
I think log files are increased when transaction are increased, correct or not. If it is not then when they can increased.
Thanks & Regards,
Suresh K |

You may have to restart your queue manager for the changes to take effect.

Hi Exerk,
Thanks for Response...
Yes it will effect only after queue manager has restarted .
If a queue manager has a linear logging option then only it will effect otherwise it will not effect I already double checked is it correct or not.
Thanks & Regards,
