3. Creating an HDLM Environment
141
You can set up the trace level for a trace file hdlmtrn.log (n indicates a file number
from 1 to 64).
Table 3-16: Values for the Trace Level Setting lists and describes the possible values
for the trace level setting.
Table 3-16: Values for the Trace Level Setting
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.
(7) 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
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.
