I have a simple question, I guess. How can I run a remote runnable job on a remote machine?

Remote runnable means: I define a job on machine 1, but I can on run the job on (not only from) machine 2.

I use 2 machines. A job is defined in machine 1, it's a simple 'uname -a'. The job is marked as remote runnable. Machine 2 can see the job. I use gbch-xq to check the existence and parameters of the job on both machines.

Now I try to run the job on machine 2. I use 'force' in the context menu of gbch-xq on machine 2 to run the job. The result is a mail on machine 1 with the uname-result for machine 1. This means that the job was executed on machine 1, but not as expected on machine 2.

I have no clue how to run a remote runnable job on a remote machine. I couldn't find any hint in the 3 PDF doc files on this topic. Or did I understand something completely wrong? Could somebody please give me a hint on how to run a remote runnable job on a remote machine?

is it working if you use gbch-rr to send it to a remote machine directly, i.e. specifying the machine?

Try setting LOADLEVEL to zero then making the job remote runnable and then ready to run - it should then do it. The trouble with what you are doing is that that the "nearest" machine - the local machine will grab it first before the other machine gets a look in.

The original idea of remote runnable is load balancing. But it hasn't been used nearly as much as gbch-rr and I'm not 100% sure that the lock code is bulletproof.

You could make a condition that it doesn't run on the same machine it's submitted on by saying MACHINE!='localmachine".

You can also use a so-called "clustered" variable (I don't know why it's called that it wasn't my name) which is "sticky" about using the local machine's version of that variable. But don't get in the habit of using that, I know it's wrong.

Rel 2 of GNUbatch will just use "XYZ" to mean the local copy of that variable on whatever machine it's run on and "ABC:XYZ" to mean specifically the variable XYZ on machine ABC.
