3. Creating an HDLM Environment

3.11 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 to increase 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 3-30: Default and recommended values for the integrated trace file settings

shows the default and recommended values for the integrated trace file settings.

Table 3-30: Default and recommended values for the integrated trace file

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. If an earlier Hitachi Network Objectplaza

Trace Library (HNTRLib) is already installed, the settings will not be inherited.

3.11.1 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.
