from 1 to 64).
Table 3-59: Values for the Trace Level Setting lists and describes the possible values
for the trace level setting.
Table 3-59: Values for the Trace Level Setting
If an error occurs, you might have to set the trace level to 1 or higher to collect any
trace information.
The higher this value is set, the more information that will be output. As the amount of
trace information to be output increases, it will take less time to overwrite the old trace
information with the new information.
For normal operation, we recommend that you set the trace level to 0. If you set the
trace level to a value higher than necessary, HDLM performance might decrease, or
trace information required to analyze the cause of an error might be overwritten.
The following is an example of using a command to set the trace level.
# /opt/DynamicLinkManager/bin/dlnkmgr set -systflv 1
Specify the trace level as a number.
(7) Setting the Error Log File Size
The error log file size (the HDLM manager log (
dlmmgr
n
.log
( n indicates a file
number from
1
to
16
))) can be set.
You can specify a value (in KB) from 100 to 2000000 for the error log file size. The
specified value is applied for HDLM manager logs.
When an error log file reaches its maximum size, the information in the oldest error
log file will be overwritten with new information. By specifying both the log file size
and the number of log files, you can collect up to 32000000KB (approximately 30GB)
of error log information.
The following is an example of using a command to set the error log file size.
Value Description
0 No trace is output.
1 Only error information is output.
2 Program operation summaries are output.
