The following list is an explanation of the main setup options and fields found on the Oracle ODBC Driver Configuration dialog box shown in the preceding graphic. The tabs found on the lower half of this dialog box are described in subsequent topics.

For example, 'odbc-pc'. You must enter a DSN. Description - A description or comment about the data in the data source. For example, 'Hire date, salary history, and current review of all employees. User ID - The user name of the account on the server used to access the data. For example, 'scott'. The User ID field is optional. You can provide the other information requested in the dialog box or you can leave the fields blank and provide the information when you run the application.

In addition to the main setup options previously described, there is a Test Connection button available. When you press the Test Connection button, you are prompted for the username and password.

The following list is an explanation of the fields found on the Application Options tab shown in the preceding graphic:. If Result Sets are not required for your application, Result Set support can be disabled.

There is a small performance penalty for procedures called from packages not containing Result Sets. Result Sets are enabled by default. Query Timeout is enabled by default. Read-Only Connection - Check this box to force read-only access. The default is write access. Enable Closing Cursors - Enables closing cursors. By default, closing cursors is disabled the field is empty , meaning a call to close a cursor does not force the closing of OCI cursors when this behavior is not desired because it can cause an unnecessary performance hit.

Enable closing cursors when you want to force the closing of OCI cursors upon a call to close a cursor. Enable Thread Safety - Thread safety can be disabled for a data source. If thread safety is not required, disabling this option eliminates the overhead of using thread safety. By default, thread safety is enabled.

Batch Autocommit Mode - By default, commit is executed only if all statements succeed. Numeric Settings - Allows you to choose the numeric settings that determine the decimal and group separator characters when receiving and returning numeric data that is bound as strings. The following list is an explanation of the fields found on the Oracle Options tab shown in the preceding graphic:.

Fetch Buffer Size - The amount of memory used to determine how many rows of data the ODBC Driver prefetches at a time from an Oracle database regardless of the number of rows the application program requests in a single query. However, the number of prefetched rows depends on the width and number of columns specified in a single query.

Applications that typically fetch fewer than 20 rows of data at a time improve their response time, particularly over slow network connections or to heavily loaded servers. Setting Fetch Buffer Size too high can make response time worse or consume large amounts of memory. There is a small performance penalty for insert and update statements when LOBs are enabled.

Enable Statement Caching - Enables statement caching feature, which increases the performance of parsing the query, in case the user has to parse the same text of query and related parameters multiple times.

The default is disabled. The default cache buffer size is 20 that are used only if statement caching option is enabled. Setting cache buffer size to 0 disables statement caching feature. The default size is 8 KB bytes. The maximum value that can be set is KB bytes.

Translate ORA errors - Any migrated third party ODBC application, which is using the SQL Translation Framework feature, expects that errors returned by the server to be in their native database format, then users can enable this option to receive native errors based on the error translation registered with SQL Translation Profile.

Convert Empty String - Any third party ODBC application that is migrated to Oracle Database requires handling empty string data Oracle Database does not handle empty string data in table columns , then they can enable this option so that the application can insert empty string data or retrieve empty string data. Enable this option to configure additional failover retries.

To solve this, we need to copy or create the tnsnames. Open Notepad and then copy and paste these lines and then save it as tnsname. After that, we need to tell the system to use this tnsnames. Open the Environment Variable again and add a new entry with the following value:. Now you should be able to pick or select the TNS service.

EXE, Thread: 1 Windows 8 I tryedl everything, and no solution. This feature will be removed in a future version of Windows. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

Oracle RDBMS is a multiuser relational database management system that runs with various workstation and minicomputer operating systems. IBM-compatible computers running Microsoft Windows can communicate with Oracle database servers over a network.
