I dont think there will be any impact other than changing the IP address for the host system (the server where datastage is installed) .If the database is installed in a different server other thn the server where datastage is installed check with your DBA to configure it accordingly
The connection between client and server does not depend upon that, as far as i know. All you need is the correct server name, username and offcourse, password. Your in.
Creativity is allowing yourself to make mistakes. Art is knowing which ones to keep.
That is correct , in case a server name is specified for the host when you connect to datastage you dont need any change, if you use IP address you need to
If, for some reasons, you have hard-coded the mapping between server name and IP address in the hosts file on your client machine, you will need to correct this.
