Verifying and extracting electronic images

If you download the installation files from IBM® Passport Advantage®, before you install the software, verify the completeness of the downloaded files and extract the electronic image from the files. If you select the Download Director option for downloading the installation files, the Download Director applet automatically verifies the completeness of each file that it processes.

About this task

As you extract the installation files from the downloaded compressed files, follow these steps:

Procedure

Preserve the directory structure of the downloaded compressed files
Extract the contents of all the compressed files to the same directory.
You might have trouble unzipping installation files larger than 2 gigabytes. One option for handling the issue is to use 7-zip. which you can download from the following site:
- http://www.7-zip.org/download.html
For example, to extract a zip file from the command line on a Linux™ platform, use the 7z command:
- Syntax: 7z x -o[OUTPUT_DIR] [ZIP_FILE]
- Example: 7z x -o/tmp/target_dir /tmp/source/myzip.zip
That example extracts myzip.zip into the target_dir directory.
Do not include spaces in the directory names. If you include spaces, you cannot run the launchpad.sh command to start the launchpad from a command line.
