Starting Network Lines
•
Abort all transport subdevices before stopping TSP processes. This should be part
of your normal shutdown procedure.
•
Assign the same TLAM IOP to the same TSP process.
Deleting TLAM Ports
TLAM ports can only be deleted by aborting all the TSP subdevices; otherwise, TLAM
ports are retained for the lifetime of the TSP process.
If the TLAM device is not operative while a TSP process has the ports opened, the TSP
process attempts to delete them as soon as the error condition is detected. The TSP
process also tries to recreate the TLAM ports during the next attempt to establish a
connection.
Starting Network Lines
After you have installed an access method I/O process into your operating system
environment, you need to start the associated communications line. SCF defines a LINE
object corresponding to each access method I/O process that you install. LINE objects,
however, are not part of the SCF interface to OSI/TS and are not controlled by the
OSI/TS subsystem.
Use the SCF START command to start LINE objects by referring to the I/O process
directly by its device name:
START LINE $X25X
START LINE $LAMA
$X25X and $LAMA in these examples are the device names for I/O processes, defined
in the SYSGEN CONTROLLERS paragraph.
PAM Configuration Considerations
The maximum TPDU size to be used for Transport Layer connections over PAM is
limited to the maximum request size supported by PAM, as specified by the
MAXREQUESTSIZE (or MAX) attribute; the MAX default is 32000. Ordinarily, the
OSI/TS subsystem automatically determines each PAM line’s maximum request size.
However, you can override the PAM MAX value by doing one of the following:
•
Use the TSP^LANIOSIZE PARAM parameter to set the desired size when starting
the TSP process.
•
Alter the OSI/TS LANIOSIZE attribute of the PROCESS object.
Note. To change the value of the ESISENABLE attribute, you must first abort all the TSP
subdevices. If the TSP subdevices are not first aborted, unpredictable behavior can result.
