The LIMIT command limits the number of concurrently running jobs
or sessions. Maximum job and session limits are established during system
configuration. Within these limits, the LIMIT command can redefine
the job and session limits.
Syntax | |
LIMIT [{numberjobs
,numbersessions
numberjobs,numbersessions}]
|
Parameters | |
- numberjobs
Specifies the maximum number of jobs. - number-sessions
Specifies the maximum number of sessions.
If you do not specify a parameter value, the system displays the current limits.
If you specify one parameter value but not the other, the limit changes
only for the specified parameter.
Operation Notes | |
Usage You can enter this command from a session, a job, a program, or in break
mode. Pressing Break does not affect this command. You must enter this command from the console; however, you can enter
this command from your terminal if your system
administrator has used the ALLOW command, which permits you to
enter this command. Priority and nonpriority jobs and sessions Ordinarily, no new jobs or sessions can exceed the current job and session
limits; however, you can override these limits by using the HIPRI
parameter of the JOB and HELLO commands. You can specify the
HIPRI parameter only if you have SM or OP capability. You can submit a non-HIPRI
job even if the current job limit is reached, but your
job waits until it can log on without exceeding the job limit. You cannot log on as a non-HIPRI session after the session
limit is reached. If you attempt to log on, the message
CAN'T INITIATE NEW SESSIONS NOW appears. Existing job and session execution The number of jobs and sessions may already exceed the new
limit that you specify
when you enter this command, however, this does not abort currently
executing jobs or sessions. They continue to execute, but no new jobs
enter the executing state, and no new sessions are initiated.
Examples | |
To limit the number of sessions to 13, but retain the current job limit,
enter: To limit the number of jobs to 2 and the number of sessions to 15, enter:
The system responds as follows when you enter the SHOWJOB command:
JOBNUM STATE IPRI JIN JLIST INTRODUCED JOB NAME
#S24 EXEC 20 20 TUE 1:54A OPERATOR.SYS
#S26 EXEC 177 177 TUE 5:01A FUNKY,RSPOOL.S
#S96 EXEC QUIET 35 35 TUE 8:31A SLIDES.SIMON
3 JOBS:
0 INTRO
0 WAIT; INCL 0 DEFERRED
3 EXC; INCL 3 SESSIONS
0 SUSP
JOBFENCE= 6; JLIMIT= 2; SLIMIT= 15

Note the JLIMIT and SLIMIT fields showing that the new job limit
is 2 and the new session limit is 15.
