HP 3000 Series 9X8LX Computer Systems Commands Reference

LIMIT 

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 

      [{numberjobs               }]
LIMIT [{,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:

            :LIMIT,13 

   *   To limit the number of jobs to 2 and the number of sessions to 15,
       enter:

            :LIMIT 2,15 

       The system responds as follows when you enter the SHOWJOB command:
