There's a new batch que on Kim and Charm that you are free to use which will alternately submit jobs on each system in order to balance the batch job load. I highly recommend that you use this, or at least try it a few times to see if it really works. After a breakin period, I will make the procedure the default. In your LOGIN.COM (at least those on Kim and Charm), place: $ assign 780_BATCH SYS$BATCH or, if you'd rather not "break" SYS$BATCH, then do submits as: $ SUBMIT/QUE=780_BATCH bla_bla... or, $ SUB*MIT :== SUBMIT/QUE=780_BATCH/NOTIFY...etc. If you are one of those people with directories on both Kim and Charm, then read on... There could be a problem if you submit a job on Kim, it starts up on Charm executes your LOGIN.COM file on Charm and that LOGIN.COM doesn't setup the same environment as you've setup on Kim. Your batch job may fail because some symbol or logical name hasn't been defined as expected or some such thing. When we first went to common system authorization file, I chose to force everyone to use a LOGIN.COM file in a "home" directory in order to remove these kinds of problems, but that caused other problems instead. Soooo, I put it back the way it was. Now with the BATCH system, it becomes yet again slightly different. (I think this is how operating systems get so confused; the designers have to use bandaids to make the system compatable and really make a mess of things). What happens in BATCH is the system finds which disk the file you have submitted lives on. It then "pretends" to have logged in on that system for the purposes of looking for your LOGIN.COM and setting SYS$LOGIN. This will not work under all circumstances, such as submitting a .COM file that lives on a different node. Also the node conditionals that you may have in your LOGIN.COM file will NOT be fooled by this. Anyway, try it. I will probably work fine for your simple day to day stuff such as compiles, links etc.
