Hi Ruzi We are using Linear Logging on Windows for sometime. Personally, I don't see any major overheads of the Linear. Please note that one of our such queue manager generates large volume of logs because of traffic. On all our Windows servers, we have scheduled a "batch" job which runs once a day, issues rcdmqimg command, followed by my VB Script to clean up the old logs.
However so far we never needed to repair the objects (other than testing it to make sure it works) but it gives a good cosy feeling having LINEAR logs.

We have been using Circular logging for the Test queue managers. To be able to do a media recovery, I would like to use Linear logging in Production. However, my colleagues are in favor of using Circular logging instead as it does not require any maintenance/backup. They say, if an object is damaged they can re-create it manually. They are willing to live with the damaged queue and its contents by deleting and recreating the queue etc. I would like to know from the real experiences of the people using Linear logging: 1- The Admin book says If you do not take regular media images of the objects that you want to re-create, you might have insufficient disk space to hold all the log files required to re-create an object. How often do you take media images? 2-Is there a tool (preferably free) out there that could be used to retrieve selected messages from the log and put them onto a queue ? I think there are some, but I don t remember the names. 3-How often do you clean-up the logs? Of course, it depends on the how fast the files are getting full. But I just need some idea 4- Any complexities, problems etc with dealing with Liner logging?
