VTAM APPL Parameters for DB2:

                VBUILD        TYPE=APPL
--> REMTLU      APPL          AUTH=(ACQ, VPACE, PASS),
                              EAS=20
                              SONSCIP=YES,
                              SONSCIP=YES,
                              PARSESS=NO,
                              VPACING=0

DISTRIBUTED DATA FACILITY (DDF) example:

The Distributed Data Facility (DDF) is a component of your IBM database. Its primary task is to route data from one database to another or from a client to another client (distributed unit of work). If distributed data has never been implemented it may not be configured. Refer to the DB2 Administrator for the state of the component. The key information required for StarSQL is the RDB name and the LUNAME. You can find these names by running the VTAM change log inventory utility or through panels by using DSNTIPR. The line will look like this:

--->   DDF LOCATION= locname, LUNAME=REMTLU(PASSWORD=....) 

Communication Database (CDB) example:

The Communications Database (CDB) contains information regarding network attributes of the remote systems (SYSIBM.SYSLUNAMES), the association of the RDB Name (Database Server Name) to the LUName/TPN value (SYSIBM.SYSLOCATIONS), LU 6.2 session limits for each partner (SYSIBM.SYSLUMODES), mode tables for individual users (SYSIBM.SYSMODESELECT), and end user management (SYSIBM.SYSUSERNAMES).

VTAM libraries must contain definitions for DB2:

  SYS1.VTAMLST defines DB2 as a VTAM application
  SYS1.VTAMLIB contains DDF mode tables.

                NETWORK.SYSIBM.SYSLUMODES
-----------------------------------------------------
        LUNAME        MODENAME        CONVLIMIT        AUTO
--->    LOCLU1        DEPMODE         1                Y

The LUNAME parameter in CDB indicates the SNA Server Local LU Name that is also defined on the other worksheet.
