Table 3-26: 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 setting up the trace level by using a command:
# /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 kilobytes) from 100 to 2000000 for the error log file size.
The specified value is applied for HDLM manager logs.
If each error log file reaches the specified size, the information in the old error log file
will be wrapped around and will be overwritten with new information. By specifying
both the log file size and the number of log files, you can collect up to 32000000
kilobytes (approximately 30GB) of error logs in total.
The following is an example of setting up the error log file size by using a command:
# /opt/DynamicLinkManager/bin/dlnkmgr set -elfs 1000
Specify the size of the error log file in kilobytes.
Value Description
0 No trace is output.
1 Only error information is output.
2 Program operation summaries are output.
3 Program operation details are output.
4 All information is output.
