title: Pentaho error-Error connecting to database: (using class oracle.jdbc.driver.OracleDriver)
body: <p>While using an SQL select query in a table input step in pentaho DI CE version 4.3, though following error pops up:</p>
  
  <p>Error connecting to database: (using class oracle.jdbc.driver.OracleDriver)
  ORA-01017: invalid username/password; logon denied</p>
  
  <p>On rechecking, both the username and password are correct. All connection details like host name, database name, port, etc. are also set correct. The database to be connected to is an Oracle 10g via native access (JDBC). The drivers are also matching, but this error still arises randomly. Sometimes it does, sometimes not. Any ideas?</p>
