Currently the largest possible Job ID which PBS can hold is "9999999". Which is a bit low for sites submitting lot of jobs. With new enhancement the largest possible Job ID that PBS would now hold will be "999999999999". Thus the range will be (0 to 999999999999) with a total of 1 trillion unique job IDs.

Interface 3: pbs_rstat output
- Visibility: Public
- Change Control: Stable
- Details: As PBS_MAXSEQNUM increased from 7 to 12, so pbs_rstat output header also got changed slightly (increased the count of '-'(hyphen's) at the end of the line) and also need to increase the column width of "Resv ID" and "Queue". Currently, width of "Resv ID" and "Queue" is 10 and 8 so after implementation it would be become 15 and 13 respectively. These changes will definitely break the backward compatibility of pbs_rstat command.
- Given below the output of pbs_rstat command.
- Previous output:
Resv ID Queue User State Start / Duration / End
---------------------------------------------------------------------
R5.blrpc67 R5 bhagatr@ CO Today 14:00 / 7200 / Today 16:00
- New output:
Resv ID Queue User State Start / Duration / End
------------------------------------------------------------------------------- // added extra '-' here
R6.blrpc67 R5 bhagatr@ CO Today 17:00 / 7200 / Today 18:00
Example: Given below an example in which we can see the change in pbs_rstat output format:
Previous Output: If max reservation id is "9999999" and server name is "servername-cent7" then output displays like: Resv ID Queue R9999999.s R9999999
New Output: Now, if column width is increased to 15(Resv ID) and 13(Queue) and max reservation id also increased to "999999999999" then output would be like:
Resv ID Queue R999999999999.s R999999999999
Limitation: With this implementation the maximum length of Job name (PBS_MAXJOBNAME) will be limited to 230 character wide.
