Sample JCL and Parameter Statements

This section provides examples of JCL and parameter statements for running the CTCA line driver and the FCTC line driver.

Sample procedure for Entire Net-Work with CTCA line driver and the FCTC line driver:

//NETWORK     PROC     F=N
//NETWORK     EXEC     PGM=ADARUN,TIME=1440
//STEPLIB      DD      DSN=NETWRK.Vvrs.LOAD,DISP=SHR
//             DD      DSN=WAL.Vvrs.LOAD,DISP=SHR
//DDPRINT      DD      SYSOUT=*
//MPMDUMP      DD      SYSOUT=*
//SYSDUMP      DD      SYSOUT=*
//DDCARD       DD      DISP=SHR,DSN=NETWORK.SOURCE(DDCARD)
//             DD      DISP=SHR,DSN=NETWORK.SOURCE(FORCE&F)
//DDKARTE      DD      DISP=SHR,DSN=NETWORK.SOURCE(DDKARTE)

Sample parameter statements (DDKARTE) for Entire Net-Work with the CTCA line driver:

NODE ONE
*
DRIVER CTCA TRACE=Y,IORETRY=2
LINK TOTWO  CTCA UNIT=380,WE=1
LINK TOFOUR CTCA UNIT=3CO,WE=1

Sample parameter statements (DDKARTE) for Entire Net-Work with the FCTC line driver:

DRIVER FCTC TRACE=N,IORETRY=5                                      
LINK CTC-1 FCTC IORETRY=0,                     -
                UNITR=xxxx,                    -
                UNITW=xxxx,                    -
                MAXIOTIM=300,                  -  
                RCVBLKSZ=4K,RCVBLKCT=80,       -     
                SNDBLKSZ=4K,SNDBLKCT=80,       -     
                PSTATS=N,RSTATS=N,STATINT=100, -  
                WEIGHT=10,                     -   
                RESTART=(300,5)                               

Both the CTCA and the FCTC line drivers require proper tuning of the RCVBLKSZ, RCVBLKCT, SNDBLKSZ and SNDBLKCT parameters for optimum performance. Larger xxxBLKSZ values enable multiple messages to be blocked together, and larger xxxBLKCT values reduce the likelihood of delays due to buffer shortages.
