A terminal has preset-security if a value is specified on the USERID parameter
of the TERMINAL definition.
When considering the security aspects of transaction routing from a preset-security
terminal, you must remember that preset-security is an attribute of the terminal
rather than of the user who initiated the transaction routing request.
During transaction routing, a
surrogate terminal is created in the AOR to represent the terminal at which
the transaction routing request was issued. Whether the surrogate terminal
has preset security or not depends upon a number of factors:
- If a remote terminal definition exists in the AOR for the terminal at
the TOR, and specifies the USERID parameter, the surrogate terminal is preset
with this userid. If the USERID parameter is not specified in the remote terminal
definition, the surrogate terminal does not have preset security.
- If a remote terminal definition does not exist in the AOR, the preset
security characteristics of the surrogate terminal are determined from the
terminal definition shipped from the TOR. If the shipped terminal definition
has preset security, the surrogate also has preset security, unless the connection
to the AOR is defined with ATTACHSEC=LOCAL, in which case any preset security
information shipped to the AOR is ignored.
