The higher this value is set, the more information that will be output. As the
amount of log information to be output increases, it will take less time to
overwrite the old error log information with the new information.
The following is an example of setting up the error log collection level by
using a command:
# /opt/DynamicLinkManager/bin/dlnkmgr set -ellv 2
Specify the error log collection level as a number.
Setting the Trace Level
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 3-28 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 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.
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.
