Adding NCF session parameters

You can define the session parameters for NCF either by adding the sample EQQLMTAB logon-mode table or by using your own table. If you use the sample table, assemble and link-edit the EQQLMTAB table into the SYS1.VTAMLIB library concatenation for all trackers where an NCF transmitter application is defined.

Note that the APPL statement that defines an NCF application at a tracker must contain the logon-mode-table information in the MODETAB and DLOGMOD parameters.

The EQQLMTAB member of the SEQQSKL0 library contains this logon table definition plus the JCL necessary to assemble and link-edit the table:

EQQLMTAB
//LOGON JOB STATEMENT PARAMETERS
//ASM  EXEC PGM=ASMA90,PARM='OBJ,NODECK'
//SYSLIB  DD DSN=SYS1.MACLIB,DISP=SHR
//        DD DSN=SYS1.SISTMAC1,DISP=SHR
//SYSUT1  DD UNIT=SYSDA,SPACE=(1700,(400,50))
//SYSLIN  DD  DSN=&LOADSET,UNIT=SYSDA,SPACE=(80,(250,50)),
//  DISP=(,PASS)
//SYSPRINT DD SYSOUT=*
//SYSIN  DD *

         MODEENT LOGMODE=NCFSPARM,                           C
               FMPROF=X'04',                                 C
               TSPROF=X'04',                                 C
               PRIPROT=X'F3',                                C
               SECPROT=X'F3',                                C
               COMPROT=X'0000',                              C
               PSERVIC=X'000000000000000000000000',          C
               RUSIZES=X'8787'
         MODEEND
         END
//LINK  EXEC  PGM=IEWL,PARM='XREF,LIST,LET,CALL'
//SYSPRINT DD SYSOUT=*
//SYSLMOD  DD  DSN=SYS1.VTAMLIB(EQQLMTAB),DISP=SHR
//SYSUT1  DD UNIT=SYSDA,SPACE=(1700,(400,50))
//SYSLIN DD  DSN=&LOADSET,DISP=(OLD,DELETE)

If you choose to provide session parameters in another table or entry, modify the APPL definitions for the transmitter applications accordingly. Note that NCF uses an LU-type 0 protocol with a recommended minimum RU-size of 500 bytes. Do not specify an RU-size smaller than 32 bytes. NCF does not modify the session parameter specified in the LOGMODE table entry in any way.
