In our current deployment setup, we have two VMs were WTX is deployed. In each VM we have once instance of WTX launcher process running. In each launcher have multiple maps getting executed. We are looking at system recovery during failure of components. Our approach here is if one map goes down, we will inhibit the queues in the respective queue manager, so that messages will not come the maps which are not executing.

Is it correct to assume that if the launcher process is running, all the maps in it are running and vice versa. Can there be a case that some maps are running and some maps are not running, in the same launcher process? Please let me know your views on this.

I can not recall any time where one map in system was not running and the other maps in that system were active. Usually when there is a problem in one map, like a fatal error that stops it from running, it brings down the entire system. Other systems can be up and running while one system is down, but I do not believe you'll ever have a map have a serious problem and launcher stops executing it, while it still allows other maps in the system to be active. When you bring up a system, the maps in that system are read into memory for one process with one process ID under Linux, so if something causes a fatal error in the process, it should effect the entire process, not allow some other items in there to still be active. Of course, this is an educated assumption. I can only go by what I know, as I'm not a Linux expert, and can only offer my experience with WTX, and in my experience, I have never seen that situation. I will say that if it were my shop and I had to make this determination, I code under the assumption that if one map is up, they all are up.

Actually, now that I think about it, in my last 2 jobs, the way were knew a system was not up, is each system had a map that had one output card which wrote a file every 2 minutes or so, and that file just said “System 1 is up”. A batch file, whether it was under Linux, Unix or Windows, would read that file and if it was not updated in the last two minutes, a beep would go out to the support beeper, so we relied on the fact that if one map had a problem, the entire system went down, else this above process would not work. It never failed us. I think you’re good.

Hi,Thanks for your mail

But before that we need to know the launcher will run as a proces.like that how the msl will run in the system.it is like process or threads.

Can we detect that msl file using any command.Assumimg that i am manually stopped one msl how to handle or track this msl from command
