Online Documentation for Data Pump for PostgreSQL
Step 1 - Setting connection properties
At Step 1 of the wizard you should set the source and the target database connection properties.
Please note that you need to have sufficient privileges to be able to write to the destination database on PostgreSQL server.
Note: To establish connection to the source database, it is necessary to use additional software, namely data sources (OLE DB Providers and ODBC Drivers) which are distributed by DBMS developing companies and third-party developers. EMS Data Pump processes information received from the data source. The utility itself extracts neither data nor metadata from the source database. Therefore the functionality of Data Pump may be partially limited by the abilities of data source being used.
Source database connection properties
In order to set the source database connection properties, use Data Link Properties builder or select an initialization string from the list of previously built ones. To call the Data Link Properties dialog, press the Build button.
Target database connection properties
First select the connection type: local or remote.
Local connection is used to connect to PostgreSQL server running on the same machine where Data Pump for PostgreSQL is launched.
The Remote mode allows you to connect to PostgreSQL server running on another computer in the network.
You can also set the preferable database action:
Create new database
Select this action to create a new database on the target PostgreSQL server to pump data into this database.
Connect to existing database
Select this action if the target database for pumping data already exists.
If this action is selected, the target database will be dropped and then recreated (NB: you will lose all data previously stored in the specified database in this case).
Here you must specify valid authorization info to access the target PostgreSQL server: User name and Password.
The default superuser name is 'postgres' with the password specified during PostgreSQL server installation.
For remote connection you should enter PostgreSQL host name in this field, or select one from the drop-down list.
Use this field to specify a port to connect through.
Type in the name of the target database for pumping data, or select one from the drop-down list.
If necessary, use the drop-down list to specify the preferable Client encoding to be used by the application.
If you are using the EMS SQL Management Studio for PostgreSQL version of Data Pump for PostgreSQL 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.
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 PostgreSQL server)
- SSH password is the Linux/Windows user password
For details see SSH tunneling options.
To use HTTP tunneling, just upload the tunneling script to the webserver where PostgreSQL server is located, or to any other webserver from which direct connections to your PostgreSQL server are allowed. This script exposes the PostgreSQL API as a set of web-services which is used by Data Pump for PostgreSQL.
For details see HTTP tunneling options.
When you are done, click the Next button to proceed to the selecting source schemas step of the wizard.
