Batch processes

Batch processes run in the background on a machine and check out one license per session. Batch processes include crons, execution of UNIX AT and BATCH commands and '<' redirect with STDIN (standard input).

If you execute '&system' at an ARC prompt and then start another ARC session you will have started a batch process:

% arc

Arc: &system

% arc

This also applies to a batch file submitted with the AT command on

UNIX or Windows NT/2000.

 

For example, on Windows NT/2000 the following batch job is submitted:

C:\> at 8:00 /interactive /every:mwf

C:\users\fred\submit.bat

where submit.bat is a batch file that runs ARC every Monday, Wednesday, and Friday. This batch job takes its own license.

The following &system calls will NOT require additional licenses.

Each of these is case sensitive and will execute with allowable abbreviations such as &sys.
