One thing that I've found which seems to work well is to remove the PROCs from 
the JCL and put them in the JES2PARM dataset. Similar to:

PROCLIB(PROC00) DD(1)=(DSN=SYS1.&SYSNAME..PROCLIB),
                DD(2)=(DSN=SYS1.PROCLIB),
                DD(3)=(DSN=CPAC.PROCLIB),
                DD(4)=(DSN=SYS1.IBM.PROCLIB),
                DD(5)=(DSN=SYS2.PROCLIB),
                DD(6)=(DSN=SYS1.LI.PROCLIB),
                DD(7)=(DSN=DCHPN.ENDEVOR.PROD.PROCLIB),
                DD(8)=(DSN=SYS4.PRODPROC)

this has a number of advantages. First, the DSNs can be catalogued in Usercats. 
Best of all, if a DSN somehow is deleted, you get an error message and can 
respecify the concatenation during JES2 startup. Beats the hell out of a JCL 
error! I think this came in z/OS 1.8.
