Hi Arju,
Thanks for your prompt reply.
I have checked the file permission and it has got full control, So there won't be any problem in this.
Coming to accessing the object, kindly let me know how to check whether any other process locking/accessing this datafile/undo file?
One more information is when I restart the instance then everything works fine for 1 day then it got terminated due to this accessible problem.
Thanks.

Thanks Michel,
I don't find any process/backup process accessing this database! Do you have any script which will check whether this datafile is being used by any processes?
thanks.
