Problem while importing a dmp file

Hi,

I am facing the following problem while importing a .dmp file (from a tape) into solaris 8 server. Oracle : 8.1.7

I am getting the following error while using the IMP command.

" Invalid format of import utility name "
" Verify that oracle_home is properly set"

Any help regarding this is appreciated.

Thanks in advance,

regards,
Karthik
