Datastage Hostname change

Changing hostname in a running system is not easy.

If you need to change the server name where we have installed the complete IIS8 suite of product (DataStage, QualityStage, Information Analyzer, etc) 

change in hostname in /etc/hosts will not work. you must modify the Information Services Framework configuration, XMETA repository, and WebSphere Application Server configuration to recongnize the new host. So, any wrong modification on one of these configurations, then you probably are going to spend more than 1 week to debug the problem.

The better choice and one that surely works is to reinstall the product.
