Connect to Oracle (OracleToSQL)

  • Articol

Use the Connect to Oracle dialog box to connect to the Oracle database that you want to migrate.

To access this dialog box, on the File menu, select Connect to Oracle. If you previously connected, the command is Reconnect to Oracle.

Options

Provider

Select the data access provider for your connection to the Oracle database. Available providers are the Oracle Client Provider and the OLE DB Provider. The default is Oracle Client Provider.

Mode

Select either Standard, TNSNAME, or Connection String mode.

  • In Standard mode, you enter or select values for the provider, server name, server port, Oracle SID, user name, and password.

  • In TNSNAME mode, you enter the connect identifier (TNS alias) of the Oracle database, user name, and password. This is the alias of the database as defined in the local tnsnames.ora file.

  • In Connection String mode, you provide a connection string.

    Important

    We don't recommend that you use Connection String mode because the text might include passwords, and it's sent as clear text.

The default is Standard mode.

Server name

Enter the Oracle server name. The default server name is the same as the computer name. This is a Standard mode option.

Server port

If you use a port number other than 1521 (default) for connections to Oracle, enter the port number. This is a Standard mode option.

Connect identifier

Enter the Oracle connect identifier. This is the alias of the database as defined in the local tnsnames.ora file.

This is a TNSNAME mode option.

Oracle SID

Enter the SID for the database. The SID is an identifier that distinguishes the Oracle database on a computer. The default SID for a database is the first eight characters of the database name.

This is a Standard mode option.

User name

Enter the user name that SSMA will use to connect to the Oracle database.

Password

Enter the password for the user name.

Connection string

If you use the Connection String mode, enter the full connection string for the connection to Oracle.

Connection strings consist of parameter name and value pairs.

For OLE DB connection string information, see Microsoft OLE DB Provider for Oracle Overview.

For SSMA connection strings, always include the Provider parameter. Also, make sure that you include the Port parameter when you connect to Oracle.

Important

We don't recommend that you use Connection String mode because the text might include passwords, and it's sent as clear text.
