Setting the Trace Level
The trace output level can be set.
You can set up the trace level for a trace file hdlmtrn.log (n indicates a file
number from 1 to 64).
The following table lists and describes the values for the trace level setting.
Table 3-14 Values for the Trace Level Setting
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.
If an error occurs, you may 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:
# /usr/DynamicLinkManager/bin/dlnkmgr set -systflv 1
Specify the trace level in as a number.
Setting the Error Log File Size
The error log file size (the HDLM manager log (dlmmgrn.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.
When an error log file reaches the specified size, the information in the old
error log file is replaced with new information, beginning with the oldest file.
By specifying both the log file size and the number of log files, you can collect
up to 32000000KB (approximately 30 GB) of error logs in total.
The following shows an example of executing the command to set the error
log file size.
