title: Load data from one oracle database table to another oracle database table
body: <p>I want to load data from one database table to another database table.
  For example there exists table 'tbl' in db1 and db2 databases, and I want to copy all data from 'tbl' of 'db1' to 'tbl' of 'db2' in oracle.
  Any help would be appreciated.</p>
