The following items are required for ODAC:
Additional Notes on Requirements:
Note: Visual Studio Express Editions are not supported with the Oracle Developer Tools. However, ODP.NET is supported with Visual Studio Express Edition.
The instructions below apply to installing ODAC using Oracle Universal Installer. Xcopy installation instructions are included with the download itself.
1. Download the ODAC zip file into a temporary directory. 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: If an ODAC beta is installed, uninstall it before installing this ODAC release.
Automatic Setup -- New in ODAC 12c
When installing ODAC in a new Oracle Home, OUI automatically copies the Oracle local naming (tnsnames.ora) and profile (sqlnet.ora) parameter files from an existing Oracle Home into the newly installed ODAC home. In addition, OUI provides location information for these files in up to three other existing Oracle Homes if they exist. The parameter files can then be manually copied over to the new home. Tnsnames.ora and sqlnet.ora can be customized if the new Oracle Home uses a different configuration from the previous Oracle Home from which the files were copied over.
Alternatively, existing tnsnames.ora and sqlnet.ora files can be copied over from another existing Oracle Home, besides the last active one, to the new ODAC Oracle Home.
If installing into an existing ODAC Oracle Home, no new tnsnames.ora nor sqlnet.ora files will be created.
If installing onto a machine without any previous Oracle Homes present, OUI will ask the user for the database connection alias information. OUI will then automatically create the tnsnames.ora file. If no alias information is provided, no tnsnames.ora file will be created. Even if the user doesn't have all the database connection information readily available, Oracle recommends inserting placeholder values during the install process, then modifying the tnsnames.ora file later with actual values to replace the placeholders later.
Two of the most common methods for connecting an Oracle client to a database are 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:
You will need to know where this directory is before proceeding.
to this directory:
This file tells the Oracle client by what methods (e.g. EZCONNECT) Oracle client can connect to the Oracle database server.
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.
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. The following instructions assume you will have to create a new tnsnames.ora file.
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>)))
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:
<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:
Check whether oci.dll in the existing ORACLE_HOME directory has been removed during the uninstall process. If oci.dll was not removed, follow these steps to remove the DLL.
a) Rename oci.dll to oci.dll.delete.
b) Reboot your machine.
c) Delete oci.dll.delete, which should no longer be in use after rebooting.
d) Install the new ODAC.
ORACLE_HOME\odp.net\PublisherPolicy\2.x directory. In addition, the installation of ODP.NET will place ODP.NET policy DLLs into the GAC so that existing applications can start using the newly installed ODP.NET version immediately. However, if this is not desired, be sure to remove the policy DLLs from the GAC.
