How to unzip Spectrum installer zip package in UNIX environment

Product Feature: Installation / Upgrade


You will get an error if you try to run the "unzip" command such as the one below:

End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of or, and cannot find, period.


By default, AIX does have an option to unzip .zip files, it's just a little bit hidden. Normally one would use 'unzip' but that's not available by default. You can install it as a rpm, but that's not necessary. Java is installed by default and is also capable of unzipping .zip files.

Use the following steps to use the unzip function:
  1. Add the java utilities directory to your path
  2. Unzip the file using jar
In example:
export PATH=$PATH:/usr/java5/bin
jar -xvf
