Only if internal openFT communication is performed via VTAM is it necessary to generate the VTAM applications for internal openFT data communication.
VTAM applications for internal openFT data communications
If internal openFT data communication is performed via VTAM then VTAM applications with the following predefined application names must be generated:
FJNADM (only for the STD instance) FJNNDMS0 FJNNDMS1 . . . FJNNDMS9 FJAftid FJDftid
Where ftid is the FT identifier. This alphanumeric character string may consist of a
maximum of five characters and must be unique for all linked FT systems. This ftid must also be specified in the FJGEN command (see FJGEN - Set installation parameters) for the openFT instance. The entries FJAftid and FJDftid must exist for each openFT instance that uses internal communication via VTAM. These are the instances for which CMD_TRANS=TCP is not set in the PARM member of the parameter library.
The VTAM applications FJNADM, FJNNDMS0,... , FJAftid and FJDftid are used for internal openFT communication. FJNADM is only used by the instance STD. As a minimum requirement, you must generate the applications FJNADM and FJNNDMS0. Up to 10 applications (in continuous ascending order from FJNNDMS0 to FJNNDMS9) can be generated. This provides users with more connections for the entry of the commands (this also applies to the program interface and menu interface).
These VTAM applications are generated using the following statements:
VBUILD TYPE=APPL
FJNADM APPL ACBNAME=FJNADM, X
AUTH=(ACQ,VPACE), X
DLOGMOD=FJMLMOD, X
MODETAB=modtab, X
PRTCT=ft-password, X

where
modtab
is the name of the LOGON mode table (see Extending the LOGON mode table (and, if applicable, the COS table)),
ft-password
is the FT password which can be used to protect the VTAM applications, the request file, the partner list and the trace files of an openFT installation. The password is specified in the installation parameters (see Setting up the FT parameter library) or in the FT administration command FJGEN (see FJGEN - Set installation parameters). The applications FJNNDMS0 ... FJNNDMS9 must not be protected by an FT password. For all other applications, password protection is optional.
The entry DLOGMOD=FJMLMOD is essential in these statements.
