Dear All,  
I want to restrict user of specific queue in a such way that only one job should run for each user at once, and if he submit another job then it should go in queue ?

Please try this  
qmgr –c “s q myqueue max\_run = ‘[u:PBS\_GENERIC=1]’”

It should be “u” and not “o” – updated

Please check: Table 5-12: Specifying Limits - AG-294 - PBS Professional 19.2.3 Administrator’s Guide
