Limits the number of concurrently running jobs/sessions. (Native
Mode)
Operation Notes |
 |
Maximum job and session limits are established by the system
supervisor during system configuration. Within these limits, the
operator may redefine the job and session limit with the LIMIT
command. When the system is restarted from disk in a START RECOVERY,
the operator defined limits are retained. When any other startup
option is used, the values configured by the supervisor take effect.
If you enter one parameter and omit the other, the limit of
the omitted parameter remains unchanged.
No new jobs or sessions are dispatched that would cause either
of these limits to be exceeded, unless they are initiated with the
HIPRI parameter
of the JOB or
HELLO commands.
Jobs that belong to individual job queues cannot begin execution
while the specific job queue limit is exceeded. Even if a specific
job queue limit is not exceeded, the global system job limit must
also not be exceeded in order for the job to begin execution.
Non-HIPRI
jobs can still be introduced when the limit is achieved, but they
do not execute.
If you attempt to log on to a non-HIPRI
session after the limit has been reached, you receive the message:
CAN'T INITIATE NEW SESSIONS NOW |
The specified limits may be exceeded at the time the command
is issued. This does not cause jobs or sessions executing at the
time to abort. They continue to execute, but no new jobs are allowed
to enter the executing state, and no new sessions are initiated.
Use |
|
This command may be issued from a session, job, program, or
in BREAK. Pressing Break has
no effect on this command. It may be issued only from the console
unless distributed to users with the ALLOW
command.
Examples |
|
To limit the number of jobs to 2 and the number of sessions
to 15, enter:
LIMIT 2,15
