Warm Starting a Scheduler
This subsection describes the steps in the warm-start procedure. For information on
processing that occurs during a scheduler warm start, see Warm-Start Events on
page 3-21.
Step 1: Log On as a NetBatch Supervisor
You must be a NetBatch supervisor to run NETBATCH and to use the START
SCHEDULER command. Users who are not NetBatch supervisors cannot perform
warm-start tasks.

Step 2: Run the Scheduler Program
Run the NetBatch program NETBATCH:
•
Do not specify the ! parameter in the RUN NETBATCH command when warm
starting a scheduler.
•
When the scheduler’s previous log file was a disk file and the scheduler
encounters a file-system error on that file, this warning appears:
*WARNING* Scheduler log-file chaining lost: Error file-
system-error-no.
Continuing...
The warning, which has no effect on the scheduler, indicates a break in the disk log
file sequence. As a result, log file scanning by the STATUS-HISTORY command
