| Oracle | |
| This is a compiled connection strings reference list on how to connect to Oracle. |
|
| ODBC |
|
| New version |
| |
Driver={Microsoft ODBC for Oracle};Server=myServerAddress;Uid=myUsername;Pwd=myPassword;
|
|
| |
| Old version |
| |
Driver={Microsoft ODBC Driver for Oracle};ConnectString=OracleServer.world;Uid=myUsername;Pwd=myPassword;
|
|
| |
| OLE DB, OleDbConnection (.NET) |
|
| Standard security |
| This connection string uses a provider from Microsoft. | |
Provider=msdaora;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;
|
|
| |
| Trusted connection |
| |
Provider=msdaora;Data Source=MyOracleDB;Persist Security Info=False;Integrated Security=Yes;
|
|
| |
| Standard Security |
| This connection string uses a provider from Oracle. | |
Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;
|
|
| |
| Trusted Connection |
| |
Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;OSAuthent=1;
|
|
| |
| Oracle.DataAccess.Client.OracleConnection |
|
| Standard |
| |
Data Source=TORCL;User Id=myUsername;Password=myPassword;
|
|
| |
| Using integrated security |
| |
Data Source=TORCL;Integrated Security=SSPI;
|
|
| |
| Using ODP.NET without tnsnames.ora |
| |
Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;
|
|
| |
| OracleConnection, Oracle Data Provider, ODP.NET, System.Data.OracleClient.OracleConnection |
|
| Standard |
| |
Data Source=MyOracleDB;Integrated Security=yes;
|
|
| This one works only with Oracle 8i release 3 or later |
| |
| Specifying username and password |
| |
Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;Integrated Security=no;
|
|
| |
| Omiting tnsnames.ora |
| This is another type of Oracle connection string that doesn't rely on you to have a DSN for the connection. You create a connection string based on the format used in the tnsnames.ora file without the need to actually have one of these files on the client pc. | |
SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));uid=myUsername;pwd=myPassword;
|
|
| |
|
| Some reported problems with the one above and Visual Studio. Use the next one if you've encountered problems. | |
Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;
|
|
| |
| Using Connection Pooling |
| The connection pooling service will create a new pool if it can't find any existing pool that exactly match the new connections connection string properties. If there is a matching pool a connection will be recycled from that pool. | |
Data Source=myOracleDB;User Id=myUsername;Password=myPassword;Min Pool Size=10;Connection Lifetime=120;Connection Timeout=60;Incr Pool Size=5;Decr Pool Size=2;
|
|
| |
| Windows Authentication |
| |
Data Source=myOracleDB;User Id=/;
|
|
| |
| Privileged Connection |
| With SYSDBA privileges | |
Data Source=myOracleDB;User Id=SYS;Password=SYS;DBA Privilege=SYSDBA;
|
|
| |
| Privileged Connection |
| With SYSOPER privileges | |
Data Source=myOracleDB;User Id=SYS;Password=SYS;DBA Privilege=SYSOPER;
|
|
| |
| Utilizing the Password Expiration functionality |
| First open a connection with a connection string. When the connection is opened, an error is raised because the password have expired. Catch the error and execute the OpenWithNewPassword command supplying the new password. | |
Data Source=myOracleDB;User Id=myUsername;Password=myPassword;
oConn.OpenWithNewPassword(sTheNewPassword);
|
|
| |
| Proxy Authentication |
| |
Data Source=myOracleDB;User Id=myUsername;Password=myPassword;Proxy User Id=pUserId;Proxy Password=pPassword;
|
|
| |
| Core Labs OraDirect (.NET) |
|
| Standard |
| |
User ID=myUsername;Password=myPassword;Host=ora;Pooling=true;Min Pool Size=0;Max Pool Size=100;Connection Lifetime=0;
|
|

| Data Shape |
|
| MS Data Shape |
| |
