Working with backup sets : Oracle database backup sets (Windows or Linux) : Creating a Oracle database backup set (Windows DS-Client) : Specifying the server
 
Specifying the server
1. Browse and select the server you want to backup. For Oracle on Windows, expand the Microsoft Windows network tree.
2. By default, DS-Client uses the current user’s logon credentials to connect to the selected computer. If you need to specify alternate credentials, select the Ask for Network Credentials check box, and then click Next.
The Ask for database credentials check box is selected by default.
 
Ask for network credentials
Type a valid user name and password for the selected computer.
The Network Credentials must also be valid for the Network Protocol you select to dump the database file.
The Network Credentials you specify must have read and write privileges for the dump path you select.
Ask for database credentials
(Mandatory) Type a valid user name and password for the database server.
Type the Service name in the corresponding field:
This is the name of the Oracle service database you wish to back up.
The Service Name is the TNS alias that is specified in the “tnsnames.ora” file on your Oracle client.
For Oracle 12c databases:
If you supply the service name defined at CDB-level, you will be able to browse the entire container database (Root and all pluggable databases).
If you supply the service name defined at PDB-level, you will be able to browse that specific pluggable database only.
3. (If applicable) In the Enter Network Credentials dialog box, type a valid user name and password for the selected computer, and then click OK.
The network credentials must also be valid for the network protocol you select to dump the database file.
The network credentials you specify must have read and write privileges for the dump path you select.
4. In the Enter Database Credentials dialog box, type a valid user name and password for the database server.
5. Type the service name in the corresponding field. This is the name of the Oracle service database you want to back up. The Service Name is the TNS alias that is specified in the “tnsnames.ora” file on your Oracle client.
For Oracle 12c databases:
If you provide the service name defined at CDB-level, you will be able to browse the entire container database (Root and all pluggable databases).
If you provide the service name defined at PDB-level, you will be able to browse that specific pluggable database only.
