CONTROL TCP
After creating 10 primary process and 10 backup process dump files, the TCP
process stops performing memory dumps. This prevents writing over existing
dump files that may indicate the original cause of a problem, and prevents filling
a disk with dump files.
OFF
directs the TCP process not to write data stack information to a file when it
encounters an internal or fatal error.
STATS { ON | OFF }
specifies whether to enable or disable the statistics collection mechanism within the
TCP process while the TCP is running.
If you omit this attribute, the default is OFF.
Considerations
•
Changes made by the CONTROL TCP command are recorded in the appropriate
PATHMON configuration files. The changed values are preserved during a warm
start; initial attribute values specified for the configuration are reinstated at the next
cold or cool start.
•
If you request the help of your Compaq representative in analyzing a problem, the
representative will likely require a dump file. It is therefore recommended that you
always set the DUMP option to ON for production systems.
Example
The following command sets the DUMP attribute to ON for the TCP process managing
the terminal named TERM32:
CONTROL TCP TERM32, DUMP ON
ON Resets all STATS counters to zero and then activates the
statistics collection mechanism.
OFF Resets all STATS counters to zero and then deactivates the
statistics collection mechanism.
Note. You must enter all STATS commands before issuing the CONTROL TCP command
with the OFF attribute because this attribute resets all the statistical counters to zero.
