SET TCP Command
OFF
directs the TCP not to write data stack information to a file when it encounters
an internal or fatal error.
GUARDIAN-LIB file-name
specifies the name of the library object file that contains additional TCP code
space for user conversion routines. If you supply a value for this attribute, the
operating system uses this file name and the file named in the PROGRAM attribute
to access the TCP object code. For example:
SET TCP PROGRAM $VOL1.SUBVOL1.PATHTCP2
SET TCP GUARDIAN-LIB $VOL1.SUBVOL1.PATHTCPL
In this example, whoever starts the PATHMON process must have WRITE and
EXECUTE access to the object file PATHTCP2.
After starting the TCP, the operating system modifies the TCP object file to point to
the user library file that you define with this attribute. To change the user library file
name, you must stop the TCP and alter this attribute value. Stopping the TCP does
not change the user library pointer in the TCP object file.
All TCPs running simultaneously and using the same object code must also use
the same user library object file. You can build the TCP user library object file by
using the nld program development tool for combining object files. For more
information, see the HP NonStop Pathway/iTS TCP and Terminal Programming
Guide.
If you do not specify a node name, the default node for file-name expansion can be
affected by several factors, including values you specify for the TS/MP CMDVOL
command and the NODEINDEPENDENT attribute of the NonStop TS/MP SET
PATHWAY command. For details, see Specifying Node Independence on page 2-5.
A PATHMON default value for this attribute does not exist. If you omit this attribute,
the operating system uses the library file specified in the program object file
PATHTCP2. Usually this file is on $SYSTEM.SYSTEM.PATHTCPL.
The TCP is capable of supporting double–byte character devices, including 6530
devices and IBM 3270 devices. To enable double–byte character support in
Pathway/iTS, you need to have product T9115, Multibyte Character Services Base
(MBCS).
GUARDIAN-SWAP $volume
specifies the Guardian operating environment name of the disk volume for the
swap file formerly used by the operating system for memory swaps of the TCP
data area (that is, user data not in the TCP extended data segment). Allocation of
this swap file is now handled by the Kernel Managed Swap Facility (KMSF) on
behalf of the TCP, and the value of this parameter is not used. However, if you
specify a value for this parameter, it must represent an existing device, or an error
occurs.
