SET TCP
After starting a 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 TCP processes 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.
Defaults for file name expansion are based on the values of the SYSTEM and
DEFAULT attributes of the associated NODE object.
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.
TCP processes are capable of supporting double–byte character devices, including
T16-6530 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 name of the disk volume for the swap file used by the
operating system for memory swaps of the TCP data area (that is, user data not in
the TCP extended data segment).
For Pathway/XM environments running on operating-system versions D40.00 or
more recent, the operating system allocation of this swap file is handled by the
Kernel Managed Swap Facility (KMSF) on behalf of the PATHMON process. Any
value specified for this parameter is not used. However, if you specify a value for
this parameter, it must represent an existing device, or an error occurs.
Defaults for file name expansion are based on the values of the DEFAULT and
GUARDIAN-SWAP attributes of the associated NODE object.
HIGHPIN { ON | OFF }
specifies whether a TCP runs at a high PIN or a low PIN.
If you omit this attribute, the default is OFF.
For a TCP to run at a high PIN, the HIGHPIN flag must be set in the PATHTCP2
file. The HIGHPIN flag is set by default for this file.
ON The TCP runs at a high PIN.
OFF The TCP runs at a low PIN.
