Job Classes

Gold Camp

Customers can control the execution priority of their job and the shift (Prime Shift, Off-Shift, Weekend) on which the job will process with the use of a Job Class. Selection of the proper class is important for efficient job processing. As an example, Class 'A' is the system default; Class 'E' is an 'express' class and will process faster than Class 'A' but cannot be used for jobs requiring tape mounts. Other factors, such as sorts or the availability of online databases, help determine the class to use.

A one-character Job Class can be coded on either the JOB statement or MAIN statement; however, Job Classes having two or more characters must be coded on the MAIN statement.

Customers should contact the Service Desk to schedule a job which requires:

  • A region size greater than 8M.
  • More than 8 hours of execution time.

Prime Shift - Jobs requesting prime shift processing are eligible to begin execution when submitted, regardless of the shift or day of week.

Off-Shift - Jobs requesting off-shift processing are not eligible for execution until 1700 hours, Monday through Friday, and anytime during the weekend.

Weekend - Jobs requesting weekend processing are eligible to begin execution on weekends only, regardless of the day of the week or shift submitted.

Weekend hours are: midnight Friday through 2100 hours Sunday, and 0145 through 0700 hours on Monday (2100 hours Sunday through 0145 hours Monday is reserved for system maintenance).

Refer to the Job Class Table below prior to submitting a new job.

JES determines job classes by CPU time as coded on the job statement and number of tape drives needed. These are the classes available on the shared system.

Class # of Drives CPU Time Qualifiers
A 3 20 Minutes -
B 3 No Limit -
C 4 20 Minutes -
D 4 No Limit -
E 5 to 8 20 Minutes -
F 5 to 8 No Limit -
G No Limit No Limit Job submitted by ESP
H No Limit No Limit Job submitted by ESP and has a /*WHILE card
K - - EDP007 to print spooled data
L 2 - Pre-allocated sortwork area
M 3 No Limit Has a /*WHILE card
P 0 10 Minutes -
Q 2 10 Minutes -
R 0 1 Minutes Has a /*WHILE card
S - - OTECH Software
V - - Runs when ADABAS monitor is up (/*HWDCPARM ADABAS)
W 2 - Production with pre-allocated sortwk
X - - CICS and ADABAS regions
Y - - Production
0 0 1 Minute -
1 1 1 Minute -
2 2 4 Minutes -
3 3 4 Minutes -
4 4 4 Minute -
6 - - NCCF jobs
7 3 to 4 reels - -
9 - - Uses a combination of resources which requires special operator handling. Usually not run during prime time.

Local JES2 Extensions at Vacaville

The Office of Technology Services has made several extensions to JES2 which give the user the ability to control certain aspects of when and where their jobs run.

  • These extensions are implemented using the locally developed control cards /*AFTER, /*WHILE and /*HWDCPARM.
  • The /*AFTER JJJJJJJJ control card is used to request that your job wait until after task JJJJJJJJ finishes running.
  • The /*WHILE JJJJJJJJ control card is used to request that your job run on the same system as task JJJJJJJJ and while it is running.
  • The /*HWDCPARM card has several parameters which can be coded to influence the running of your job.
  • The NIGHT parameter requests that your job be run after midnight.
  • The ATIME=HHMM parameter requests that you job be run after HHMM (using a 24 hour clock).
  • The ADABAS parameter requests that your job in class V (you should also code a /*WHILE card for the appropriate monitor).

It is possible to combine the cards to do special things such as using a /*AFTER card and a /*HWDCPARM ATIME=1800 to request that your job runs after a CICS monitor comes down after 6 p.m. This will allow you to submit your job any time of the day and be assured that even if the CICS region is restarted during the day, your job will not interfere with the restart. You can also use /*HWDCPARM NIGHT,ATIME=0200 to request that your job be run at 2 a.m. the next morning.
