If exp80 and imp80 are not available, are exp and imp available? Many years ago on the Windows platforms, Oracle's utilities had a version number in the utility name. The exp80 utility was the export utility for verions 8.0. If you are running a newer version (8i or higher), the utility names in Oracle dropped the version number from the name. You should have export/import utilities in your %ORACLE_HOME%bin directory. You can take a full export as a backup of your database in this case. You can also perform an export using Oracle's Enterprise Manager.
The easiest way to back up your system is to first find out the datafiles you need. Issue the following queries:
select file_name from dba_data_files; select name from v$controlfile; select member from v$logfile;Now shut down your database with SHUTDOWN NORMAL or SHUTDOWN IMMEDIATE. Use OS commands to copy all of the files returned from the above queries. Finally, make sure to copy your parameter file and password file (if applicable).
