Most of Netcool product installer now come with Prerequisite Scanner, which analyzes system environments before the installation or upgrade of a Tivoli product or IBM solution... it is a great tool however it may reports empty result as below:
It is recommended to review the Prerequisite checking results before proceeding... With empty output there is no way you can find if the check is successful.
The most common reason is because 'ksh' is not installed... Prerequisite checking tool use ksh as the default script and by default ksh is not installed on most OS except AIX.
To fix this please install ksh before starting the installation process... Ideally ksh should be listed as required package in product installation guide.
