HIJBNUM

[Phontilla Shuffitt]

In 11.3 the max of this number is 9999 and is used for job numbers similar to how JES job numbers are assigned when a job is submitted.  But at what point do these numbers recycle?

Are there any warning messages that can be captured when % is used to prevent CA7 from stop being operational?

I see that in release 12 CA7 will allow 32,767 max, anyone know why this odd number?  

Thanks for your insight, stay safe.

Hi Phon..... 
 
CA 7 will use up to the hi job number (HIJBNUM) and then start over using available job numbers starting with 0001. If a cold type of start is done, it will reset the values and start with lowest available number.

Use command: /DISPLAY,ST=HIJBNUM to see current values.
 
Yes, you will get the following wto warning messages when the job numbers are over 80% and relieved:
 

CAL2A101W ** WARNING ** [80/90]% of CA 7 Job Numbers in use ([Rising/Declining])

CAL2A102E ** WARNING ** 100% of CA 7 Job Numbers in use. No new jobs can enter the system ** WARNING **

As job numbers are released, the WTOs are also updated as the percentage decrements, until it reaches 70 percent. At 70 percent, a general WTO is issued.

CAL2A103I ** CA 7 Job Number Shortage Relieved **
 
32767 was used because that what would fit in a half word (assembler code talk).
