Anil,
I recieved a similar error last week. The issue appeared to be related to our upgrade to Oracle 10g.
After the upgrade, I created dimensions within the UI which attempted to create a Sequence and Trigger for the dimensions through Oracle. These failed because 10g requires specific grants to create sequences,triggers,etc…
No error message appeared within the UI but what I noticed was none of my monitors were collecting data. I then saw the error message above.
let me know if this helps.
