Defining, starting, and stopping the NPF FSS writer

Put your short description here; used for first paragraph and abstract.

Table 1 describes how to define, start, and stop the NPF FSS writer on various levels of JES. Before issuing any of these commands, the procedure to start the NPF FSS writer must be catalogued in a system or recognized PROCLIB. See Creating the NPF FSS writer start procedure.

Because the JES capture point is defined as a functional subsystem, only the JES commands ($SPRTx or *S,PRTx) can be used to start the NPF writer. The MVS™ START command cannot be used to initiate the writer.

Level How to Define How to Start or Stop
JES2 Version 6

The functional subsystem and FSS writer definitions can be specified either through JES initialization parameters or by entering commands interactively.

The following example shows the initialization parameters to define an NPF FSS called TCPFSS which points to a start procedure called FSWTR. It also defines two FSS writers called PRT5 and PRT6 that process class D output. 
(optional:)
DESTID(DEST1) DEST=U1
(optional:)
DESTID(DEST2) DEST=U2
 
FSS(TCPFSS)  PROC=FSWTR,AUTOSTOP=YES
 
PRT5 CLASS=D,SEP=YES,
     SEPDS=NO,
     DRAIN,MODE=FSS,
     FSS=TCPFSS,
     TRKCELL=YES,
     PRMODE=(LINE,PAGE),
     NPRO=0,
     ROUTECDE=DEST1,
     SETUP=NOHALT,
     WS=(Q,R/)
PRT6 CLASS=D,SEP=YES,
     SEPDS=NO,
     DRAIN,MODE=FSS,
     FSS=TCPFSS,
     TRKCELL=YES,
     PRMODE=(LINE,PAGE),
     NPRO=0,
     ROUTECDE=DEST2,
     SETUP=NOHALT,
     WS=(Q,R/)
The following example shows the console commands to define an NPF FSS called TCPFSS which points to a start procedure called FSWTR and to define two FSS writers to process class D output. 
$ADD FSS(TCPFSS),
     PROC=FSWTR,AUTOSTOP=YES
$ADD PRT5,MODE=FSS,
     FSS=TCPFSS,CLASS=D
$ADD PRT6,MODE=FSS,
     FSS=TCPFSS,CLASS=D
To start the FSS writer that is processing class D output, from the operator console, enter: 
$SPRT5
To stop the same FSS writer, from the operator console, enter: 
$PPRT5
To start both FSS writers, two commands are needed. From the operator console, enter: 
$SPRT5
Then enter:
$SPRT6
To stop both FSS writers, enter: 
$PPRT5
Then enter:
$PPRT6
JES3 Version 6

The functional subsystem and FSS writers are defined by JES initialization parameters.

The following example shows the initialization parameters to define an NPF FSS called TCPFSS which points to a start procedure called FSWTR. It also defines an FSS writer called PRT501 that processes class C output. 
DEVICE,DTYPE=PRT3820,
       JNAME=PRT501,
       DYNAMIC=NO,
       MODE=FSS,
       FSSNAME=TCPFSS,
       HEADER=YES,
       BURST=NO,
       NPRO=NO,
       SETUPMSG=NO,
       FORMS=(YES,STANDARD),
       JUNIT=(,SY1,S1,ON,,SY2,S2,OFF),
       PM=LINE,WS=(CL,F),WC=C
FSSDEF,TYPE=WTR,
       FSSNAME=TCPFSS,
       SYSTEM=(SY1),
       PNAME=FSWTR,
       TERM=YES,AUTOSTOP=YES
To call the FSS writer that is processing class C output, from the operator console, enter: 
*X,WTR,OUT=PRT501
To start the FSS writer that is processing class C output, from the operator console, enter: 
*S,PRT501
To enable the FSS writer to process class D output instead of class C, from the operator console, enter: 
*X,WTR,OUT=PRT501,WC=D
To stop the same FSS writer, from the operator console, enter: 
*C,PRT501
