You should search the archives on the virtues of linear vs circular because it has been discussed before and everyone's got an opinion. The platform is not really relevant because the logging depends on what type of recovery you want which is independent of your platform. Whether you are on Windows, Unix, whatever, the type of logging gives the same advantages. I figure you may want to know AIX only because of jfs logging, is that it? I would still do linear logging in production to get media recovery. If media recovery is not an issue, use circular. What you must consider is if you lose the objects and you had persistent messages, the message are gone if an object is damaged. If you had linear logging, you get the object and the messages back. If you have no persistent messages and you run saveqmgr to save off your objects, you can use circular logging since you can recreate your environment pretty easily and don't need messag
e recovery. The only thing bad is if your "auth" queue gets damaged and you didn't have linear logging, you lose your authorizations. I never experienced this, just seems like the logical result.
