We changed the OWNNODE= statement on each system to match the node number we had

assigned; we then let the SMF system ID match the node name list in order to select a node

number. We had to cold start the systems in order for the change of OWNNODE to become

effective.

11.15.1 NJE verification

On z370, zsna, and z232 we placed the following commands in the automatic startup script:

$SLOGON1

$SLINE1

We then used the console at zos1 to start the NJE network, producing the following console

activity:

ZOS1 $slogon1

ZOS1 $HASP881 LOGON1 APPLID=ZOS1NJE1,STATUS=INACTIVE

To verify that NJE was operating properly we transmitted a message from zos3 to a user on

z370, with the following results at the TSO terminal:

INMX000I 0 message and 1 data records sent as 4 records to Z370.IBMUSER

INMX001I Transmission occurred on 06/28/2003 at 19:54:09.

READY

On zos1, we saw the following message traffic indicating the file had been sent:

ZOS1 $HASP530 FLEX ON L3.ST1 4 RECORDS

ZOS1 $HASP534 L3.ST1 INACTIVE

On z370, we saw the following message indicating the file had been received:

19.54.39 $HASP540 FLEX ON L1.SR1 FROM FLEX AT ZOS1 4 RECORDS

Finally. we logged onto z370 and submitted a job to be run on sysplex member zos3 at node

ZOS1, producing the following output:

As should be expected, the job was routed to the ZOS1 node, where an initiator on system

zos3 picked it up for execution. The job output was then returned to the spool on z370, where

we displayed it with SDSF.
