The deployment procedure in the Unix and Windows is same, however I would not copy the whole directory as is. Do a fresh install on the Unix, then copy the respective VDBs and -ds.xml files. Check the log files if the Teiid started correctly or not. Red X means some issue with startup, if this is case then you cannot connect with Designer at this time.
When you have started the Teiid correctly, make sure you do not have firewall blocking the ports (31000, 31443) are open, if you are using Designer on another box.
Thanks a lot for your reply. The issue was mainly due to the fact that we had MetaMatrix running on the UNIX box and hence port 31000 was already been used by MMX process. I modified teiid-jboss-beans.xml to use a different port and the application started without any issues.
Again, thanks a lot for your help!!!
