Step 1 - Setting connection properties


At this step you should enter the necessary settings to establish connection to Oracle server.

 

Step 1 - Setting connection properties

 

 

Connection settings

 

Database Home

Specify your Oracle Home storage for this connection.

 

Connect as

Select the type of connection to be established: Normal (by default), SYSDBA, SYSOPER.

 

Authentication type

Specify the preferable type of authentication to be used for the connection:

RadioButton Windows

RadioButton Server

 

If server authentication type has been selected, you should also provide authorization settings: Login and Password.

The default superuser name is 'SYS' (for Oracle 9.0 and higher) and the default password is 'change_on_install'.

 

Optimize goal

Use the drop-down list to establish the default behavior for choosing an optimization approach for the instance:

Unchanged

Select this value to apply the approach which is currently used by the optimizer.

FirstRows

If this value is selected, the optimizer uses a mix of cost and heuristics to find the best plan for fast delivery of the first few rows.

AllRows

If this value is selected, the optimizer uses a cost-based approach for all SQL statements in the session regardless of the presence of statistics and optimizes with a goal of best throughput (minimum resource use to complete the entire statement).

Choose

This parameter value is not supported any more.

Rule

This parameter value is not supported any more.

 

After that it is necessary to specify the database you are going to work with: type in the database name in the Database field or select one from the drop-down list (the drop-down list is only available if more than one Oracle database are registered in the TNS file).

Note: If no database are registered in Oracle Client (DB list is empty in this case), then you need to add registration info manually.

 

Please note that you should have sufficient privileges to write to the destination database on Oracle server.

 

If you are using the EMS SQL Management Studio for Oracle version of Data Generator for Oracle then the Select registered database button is available. Click this button to pick a database already registered in the EMS SQL Management Studio in the Select Host or Database dialog.

 

Tunneling settings

 

To setup the connection via SSH tunnel, input the following values in the corresponding fields:

  • SSH host name is the name of the host where SSH server is running
  • SSH port indicates the port where SSH server is activated
  • SSH user name stands for the user on the machine where SSH server is running (Note: it is a Linux/Windows user, not a user of Oracle server)
  • SSH password is the Linux/Windows user password

 

For details see SSH tunneling options.

 

 

When you are done, press the Next button to proceed to the next step.
