Table 1. How JES2 resolves
destinations -- example 1

NODE2.TOM
DESTID(TOM)
DEST=NODE2.FRED
NODE2 FRED
DESTID(FRED)
DEST=BOB
NODE2.BOB
1 The destination specified on a //OUTPUT JCL
statement, NODE2.TOM, means: Send this SYSOUT to destination TOM at
Node 2.
2 JES2 determines whether Node 1 has a definition
for destination TOM. It finds a DESTID(TOM) initialization statement.
Comparing the first-level destinations and finding that they match
(that is, NODE2 on the OUTPUT JCL statement and the DEST= parameter
specifies NODE2), JES2 uses the second-level destination (FRED).
3 JES2 puts the destination of FRED at NODE2
into the NJE header and sends the SYSOUT to Node 2.
4 At Node 2, JES2 takes the incoming destination
of FRED and checks to see if it is defined as a destination identifier.
There is a DESTID(jxxxxxxx) initialization statement definition for
FRED. Its DEST= parameter specifies only a second-level identifier
of BOB. Therefore, the first-level identifier is assumed to be Node
2.
