'/home/oracle/bak'
is where to save database dump file, and ‘qsh05’ is database username.
<!--[if !supportLists]-->2.      
<!--[endif]-->Make sure '/home/oracle/bak' is created,
then execute

expdp qsh05/qsh05 dumpfile=qsh05.dmp directory=bakdir include=table

‘qsh05/qsh05’ is database username/password,
and ‘dumpfile’ is the file name of database dump file, and ‘directory’ is the
directory name created in step 1, because only need export table, so add
‘include=table’.
<!--[if !supportLists]-->3.      
<!--[endif]-->If the export is successful,
the end of log looks like following,

Dump file set for QSH05.SYS_EXPORT_SCHEMA_01 is:   /home/oracle/bak/qsh05.dmp Job "QSH05"."SYS_EXPORT_SCHEMA_01" successfully completed at 07:25:30

and go to /home/oracle/bak, there are two
files, ‘qsh05.dmp’ and ‘export.log’.
