Enabling and Disabling TCP Dumping and Statistics
Collection
Enabling and Disabling TCP Dumping and
Statistics Collection
You can use the CONTROL TCP command to enable or disable error dumping or
statistics collection for selected TCPs in a running Pathway/XM environment. For
example, the following command enables statistics collection and error dumping in the
TCPs that control all the terminals in the terminal group named INVNTRY:
>> CONTROL TCP GROUP INVNTRY, DUMP ON, STATS ON
The following command disables statistics collection in all TCPs that are in the
RUNNING state:
>> CONTROL TCP *, STATE RUNNING, STATS OFF
The DUMP and STATS option settings for TCPs are saved in the PATHCTL files for
the associated PATHMON processes, but not in the SuperCTL file. Therefore, changes
to these options are preserved through a warm start of the Pathway/XM environment,
but not through a cool start or a cold start. When the Pathway/XM environment is cold
started, the DUMP and STATS settings for all TCPs return to their initial configured
values.
For the syntax of the CONTROL TCP command, refer to CONTROL TCP
on
page 11-19.
Assigning or Changing Terminal Device or Process
Names
If you configured dummy TERM objects for future use by omitting the FILE attribute in
the PXMCFG SET TERM command, you cannot use these TERM objects until you
have assigned device or process names to them by using the CONTROL TERM
command. For example, the following command assigns the device name $AMOS to
terminal TERM-030:
>> CONTROL TERM TERM-030, FILE $AMOS
Until you have assigned FILE attribute values to the TERM objects, you cannot issue
any PXMCOM commands for those TERM objects except INFO TERM and
CONTROL TERM. After you have assigned the FILE attribute values, you can issue
START commands to activate the TERM objects.
You can also issue a CONTROL TERM command to change the device or process name
for a TERM object that already has a FILE attribute value assigned. In this case, the
TERM object must first be in the STOPPED state.
Unlike other CONTROL commands, the CONTROL TERM command has a permanent
effect. CONTROL TERM changes the initial configuration of the TERM object in the
SuperCTL file; therefore, the last FILE attribute assignment is preserved through any
restart of the Pathway/XM environment (a warm start, a cool start, or even a cold start).
For the syntax of the CONTROL TERM command, refer to CONTROL TERM
on
page 11-21.
