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.
The following table shows the 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.
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.
• If HNTRLib2 has already been installed on a host when you install HDLM,
the settings in the trace library will be inherited.
• If a different Hitachi product is using HNTRLib2 when you attempt to
remove HDLM, HNTRLib2 will not be removed
