Environment: PSF for AIX, 3900 printer                                          
                                                                                
Because of performance, more than one queue device is used for printing.        
This causes that sometimes one queue device "overtakes" an other queue          
device and the sort order of the jobs in the stacker is not the same            
as they were submitted. Is it possible to keep the order and use several        
queue devices?

How are jobs being submitted?  Is MVS Download or NPF involved to send          
jobs from MVS, or are jobs being submitted to PSF/AIX from other LAN            
clients?  If you can let me know additional detail on the customer's            
configuration, I'll be glad to get you an answer on this.                       
                                                                                
Q:                                                                              
The customer is a bank, which uses a PC based archive solution. This            
solution submits EBCDIC line data over a Novell network to an AIX               
queue. The PSF backend program has been modified to do LINE2AFP and             
ENQ (this has been done to set all necessary flags). The archive                
program submits chunks of data, which all have the same size (in terms          
of MB - not pages). I can't tell how many MB one job has, because this          
varies day by day. But they have to be printed FIFO.                           
                                                                                
A:                                                                              
In the current release of PSF/AIX for jobs coming across the LAN,               
there is no way with multiple queue devices to enforce the FIFO                 
order for printing.  I spoke with a specialist who thought that                 
this might be accomplished through some custom code (though further             
analysis of your customer's environment would be necessary); you                
may wish to pursue a fee-based services offering for this capability.
