Before trying to connect an Oracle database in Exportizer, make sure your local tnsnames.ora file contains the entry of this database. Usually, this file is located in ORACLE HOME\NETWORK\ADMIN directory. ORACLE HOME is the directory into which all Oracle software is installed; it is referenced in the application as Vendor homepath parameter (see below). Each database entry in the tnsnames.ora file has the following basic format:
database_name =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(Host = hostname)(Port = port))
)
(CONNECT_DATA =
(SERVICE_NAME = service_name)
)
)hostname, port, service_name are attributes of your Oracle database. If you don't know them, ask your database administrator.
database_name is a custom name for the database entry; you use it in Exportizer and other database applications.
Here is an example of a database entry in the tnsnames.ora:
main_db =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(Host = 192.168.100.100)(Port = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = DWH_MAIN)
)
)The file may contain multiple database entries. Try to put each entry on a separate line. No other separators are required. To learn more about tnsnames.ora file, please read Oracle documentation.
So, you can connect Oracle databases in Exportizer using these ways:
1. Opening through FD interface. Select FD interface, click Oracle, then fill all needed database parameters. Consult with your database administrator on how to choose correct parameters.
Example of configuring a database connection:
(highlighted are required parameters)
| Vendor homepath | C:\app\product\12.1.0\client_1 |
| Database | main_db |
| OS authentication | No |
| Authentication mode | Normal |
| Charset | WE8MSWIN1252 |
| Application name | Exportizer Enterprise 8 |
| User name | dexter |
| Password | ******** |
| SQL command separator | <sqlplus> |
2. Opening through ODBC DSN (interface: ADO or BDE). Select ODBC data source option and then select the ODBC DSN from the drop-down list. But first, you should create an ODBC DSN of the corresponding type using Windows administrative tools, and point it to the database.
3. Opening through connection string (interface: ADO). Select Connection string option and write a connection string. This way is the most flexible one because it allows to specify many additional parameters in the connection string and override standard Exportizer connection behavior. But it is recommended basically for advanced users. Here are basic connection strings (more examples and details can be found in the Internet):
Provider=msdaora;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword; (Microsoft OLE DB Provider for Oracle must be installed)
Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword; (Oracle Provider for OLE DB must be installed)
Driver={Microsoft ODBC Driver for Oracle};ConnectString=OracleServer.world;Uid=myUsername;Pwd=myPassword; (Microsoft ODBC Driver for Oracle must be installed)
Provider=MSDASQL.1;Extended Properties="DSN=ORACLE_DB;UID=MyUsername;PWD=MyPassword"
