DB2 Deployment Guide

-p

Specifies the full path to the root directory of the source installation image. This
directory contains setup.exe, and is the root directory of the DB2 installation
DVD.

-o

Specifies the full path to where the new DB2 pruned image is copied. Make sure
that you have write access to this directory.

The input file for

db2iprune

contains a full list of removable features and has the

.prn extension. The input file contains three keywords: PROD, LANG, and
COMP.

The PROD keyword identifies the DB2 installation image to be pruned.
The LANG keyword specifies the languages.
The COMP keyword specifies the features.

You can uncomment several COMP or LANG keywords in the same input file to
remove several features or languages.

The

db2iprune

utility removes the cabinet (.cab) files associated with those

features and languages that have not been commented out in the input file
(.prn file). Once pruned image is installed, the resulting product will only contain
a subset of features and take up a smaller footprint than that of a full DB2 product
image.

For example, if you want to remove the DB2 Configuration assistant, DB2
Control Center, as well as language support for Japanese and Korean, you have
to remove the comments from the following lines in db2client.prn (Example 3-1).

Example 3-1 Entries in the .prn file

COMP = CONFIGURATION_ASSISTANT ** Configuration Assistant
COMP = CONTROL_CENTER ** Control Center
LANG = JP ** Japanese (ja_JP)
LANG = KR ** Korean (ko_KR)

The following steps are for reducing the size of a DB2 product installation image
using the

db2iprune

utility:

1. Open the input file (.prn file) located in the

db2iprune

directory on the install

image. Uncomment the features and languages you want to remove from the
DB2 installation image by removing the asterisk(*).

2. Execute the

db2iprune

command from the command line.

db2iprune –r C:\db2rtcl.prn –p d:\ -o e:\compact_rtcl
