Hi Kiran,
expor/home/user1 is my directory & test.exp is a subdirectory under this directory. In your case spandan.exp is a sub-directory, you will have to give the entire path. For eg. if spandan.exp is under the directory /export/home/user1
the command would be
dbimport spandan -i /export/home/user1
this will create a database spandan, it will look for spandan.exp under the above directory.
