Pid               (TCT)

DESCRIPTION
In all cases except one, the "Pid" is the system process id of the process that 
handles a "Type" of TCT Screen entry. The "Host" field identifies the
machine where the "Pid" process is executing. The single exception is the "Pid" 
for a Transaction Route entry, where there is no "Pid" available to show.


VALUES
The "Pid" is a non-zero integer, usually with a maximum of 5 digits. Sun MTP has
nothing to do with determining the value of the "Pid"; the operating system
assigns the "Pid" when a terminal handler process initiates execution.


INTERPRETATION
Sun MTPScan shows the "Pid" for terminal handlers that are actually connected to
a Sun MTP system. TCT Screen entries with a blank "Pid" are either preconfigured in
the Sun MTP Terminal Control Table (TCT) or are free to be used by terminals that
are auto-installed. The TCT Screen displays preconfigured entries of the Sun MTP
TCT to make the unconnected entries visible. For such entries, most fields are 
left blank because a connection does not exist. 

The following chart shows specifically what the "Pid" means for each "Type" of 
TCT Screen entry:

3270   - for unikixb (unikixc on NCR machines), a client process that handles a
         3270 device (real or emulated) connected to Sun MTP via the XPUx (Comten
         for NCR) Server

EPI    - for the process using the EPI protocol to communicate with Sun MTP

Local  - for the unikixl terminal handler process

Remote - for the unikixs terminal handler process 

TN3270 - for the unikixtn client spawned to handle communication between Sun MTP 
         and the x3270 process that provides the user interface

TR     - not applicable


CONCLUSIONS
Sun MTPScan displays the "Pid" of the terminal handler process to enable the
administrator to kill a hung process. On UNIX systems, the kill command can be
used at command prompt to remove a hung process:

$ kill pid

where pid is the system process id. On Windows NT, the task manager may be 
used to kill a specific process identified through its system process id.
