3.8 Setting up Integrated Traces
When HDLM is used, the dlnkmgr command logs are output to the integrated trace
information files of Hitachi Network Objectplaza Trace Library (HNTRLib2) (
/var/
opt/hitachi/HNTRLib2/spool/hntr2
n.log (n indicates a file number)).
If a lot of integrated trace information is output, the older information might end up
getting deleted in a very short amount of time. Also, if a large amount of integrated
trace information is suddenly all output at the same time, any integrated trace
information that is overflowing the buffer might not be saved into the integrated trace
files. To save as much information as possible, change the settings for Hitachi Network
Objectplaza Trace Library, increasing the integrated trace file size and buffer size.
Note that if the values are too large, it will place a heavy load on the system. When
determining these values, be sure to consider these operational tradeoffs.
Table 3-20: Default and Recommended Values for the Integrated Trace File Settings
shows the default and recommended values for the integrated trace file settings.

Settings
If Hitachi Network Objectplaza Trace Library (HNTRLib2) is already installed, the
existing settings will be inherited. If you change these settings, keep in mind that
programs other than HDLM also use them.
3.8.1 Notes on Using the Hitachi Network Objectplaza Trace Library
Note the following when using Hitachi Network Objectplaza trace library:
If HNTRLib has already been installed when you install HDLM, the settings in
the trace library will not be inherited by HNTRLib2. HDLM uses the HNTRLib2
default settings.
