===========================

This issue happened many times and mostly caused by .profile and same was in my case. even though there are not many parameter/variable used in .profile.

Solution:

temporarily moving the $HOME/.profile file to temp name while running the test resolved the issue.  I will comment individual parameter sometime later to identify which particular one causing issue.

--------
Note:
Reviewing the CV LOG identified the problem. .profile was calling a interactive script which wait for user input.

Any issue we should first review the log under $ORA_CRS_HOME/cv/log (10g) / $GI_HOME/cv/log (11g onwards), they are very detailed and handy.

Thanks
