Installation Instructions

======================================================

The instructions below apply to installing ODAC using Oracle Universal Installer. For instructions on xcopy ODAC installation, refer to the README included with that particular installation.

 

1. Download ODAC 11.2.0.1.2 zip file into a temporary directory. Please note: Do not download this file into the "Tmp" directory. 
2. Unzip its contents to the directory. 
3. Run Oracle Universal Installer (OUI) by launching the setup.exe that was unzipped in the same directory. 
4. OUI will lead you through ODAC installation on your machine. After the installation, you may delete the zip file and the unzipped folders and files. 
Note: Oracle ODBC Driver and SQL*Plus are not listed separately as individually installable items in the OUI tree view control. If you wish to install these two products, choose Oracle Instant Client in the tree view control. 

Connection Setup Quick Start

======================================================

There are a number of methods to connect Oracle client to a database server. Two of the most common include EZCONNECT and TNSNAMES. EZCONNECT is the easiest to setup. TNSNAMES is much more maintainable in the long term. If you are new to Oracle, we recommend you use EZCONNECT. You only have to choose one or the other to connect.

 

These quick start instructions assume you have a valid username and password for the database server.

 

Note: In the setup instructions below, ORACLE_HOME represents the directory where the Oracle client Home was installed on your machine. A typical directory for an OUI Oracle client Home is: 
C:\app\<user>\product\11.2.0\client_1

 

You will need to know where this directory is before proceeding.

 

EZCONNECT Setup 
1. Copy the sqlnet.ora file located in the following directory: 
ORACLE_HOME\Network\Admin\Sample\ 
to this directory: 
ORACLE_HOME\Network\Admin\ 
This file tells the Oracle client by what methods (e.g. EZCONNECT) Oracle client can connect to the Oracle database server. 
2. The Oracle client must then specify a valid user name, password, and data source to connect to the database server. To specify a data source, you can use the EZCONNECT format. In the ODP.NET data source attribute, use the following format to define how the client connects to the database server: 
[//]host[:port][/service_name] 

 

• host = the database server machine's host name
• port = the database server machine's port on which it listens for incoming connection requests
• service_name = the database's global name

 

For example, some syntactically valid connection strings follow: 
"user id=hr;password=hr;data source=//sales-server:1521/sales.us.acme.com" 
"user id=hr;password=hr;data source=//sales-server/sales.us.acme.com" 
"user id=hr;password=hr;data source=sales-server/sales.us.acme.com" 

 

 If the port number is not specified, 1521 is used by default.

 

TNSNAMES Setup

 

An Oracle Net service name allows the Oracle client to use a simple alias to connect to the database server. The alias definition contains all the information needed to create a connection to the database server. Alias information is stored in the tnsnames.ora file typically located in the ORACLE_HOME\Network\Admin directory. This alias is used as the data source value in your connection string. ODAC installations do not create a tnsnames.ora file so you need to create one. Alternatively, you can copy an existing tnsnames.ora file from an existing Oracle client installation to your new ODAC installation. The following instructions assume you will have to create a new tnsnames.ora file.
 

 

1. Copy the tnsnames.ora file located in the following directory: 
ORACLE_HOME\Network\Admin\Sample\
to this directory:
ORACLE_HOME\Network\Admin\

 

<data source alias> = 
(DESCRIPTION = 
(ADDRESS = (PROTOCOL = TCP)(HOST = <hostname or IP>)(PORT = <port>)) 
(CONNECT_DATA = 
(SERVER = DEDICATED) 
(SERVICE_NAME = <database service name>) 
) 
) 

 

• data source alias = the shortcut name given to identify the connect descriptor. In the ODP.NET connection string, developers set the "Data Source" attribute to the data source alias.
• hostname or IP = the database server machine's host name or IP address
• port = the database server machine's port on which it listens for incoming connection requests. In general, this value is set to port "1521".
• database service name = the database's global name

 

The data source alias, hostname/IP, port, and database service name in the tnsnames.ora should be modified appropriately. If the TNS entries in the ORACLE_HOME\network\admin\tnsnames.ora file are not recognized by the Oracle client, create a ORACLE_HOME\oracle.key file using any text editor and type in the following line: 
SOFTWARE\ORACLE\<home key> 

where <home key> is the registry key for the ODAC Oracle Home. For example, if the default Oracle Home location was used during the install, the proper entry for the oracle.key file would be the following: SOFTWARE\ORACLE\KEY_OraClient11g_home1
