Using this method, the driver must process the entire response to a query before another query is submitted. As a general rule, applications should clean up orphaned connections at startup and when the application is notified that a connection to the server was lost. The classname and connection URL syntax for the Oracle driver are: Others Inserts are not visible. If the output parameter is char or varchar, the driver returns the output parameter value, but the returned value is limited to characters. Allows your application to use Snapshot Isolation for connections.

To validate certificates sent by the database server, set the ValidateServerCertificate property to true.

Use this value if all output parameters returned by the connection are nchar or nvarchar. An application can use the list returned by the XAResource.

The MS SQL Server Driver

The specified code page overrides the default database code page. It is cached on the server. However, if the following variables are true for your application, the best setting for this property is cursor, which means use server-side database cursors:. To improve performance when your application retrieves images, pictures, long text, or binary data, you can disable caching for long data on the client if your application retrieves long data column values in the order they are defined in the result set.

Typically, it is optimal for the client to use the maximum packet size that the server allows. InsensitiveResultSetBufferSize To improve performance when using scroll-insensitive result sets, the driver can cache the result set data in memory instead of writing it to disk. This value is stored in the hostname column of the: Use this value if all output parameters returned by the connection are char or varchar.


If set to false the default and your application has the transaction isolation level set to Serializable, the application uses the Serializable isolation level. Distributed Transaction Cleanup Connections associated with distributed transactions can become orphaned if the connection to the server is lost before the transaction has completed.

Microsoft SQL Server If set to true, the driver returns all results, including results generated by triggers.

If set to 0 the defaultthe driver uses a packet size of 64 KB. For example, to connect to Oracle instance named test on the server named corpserver1 on portthe following URL would be used: Sqlserverdrivfr using these methods to update long data as Blobs or Clobs, the updates are made to the local copy of the data contained in the Blob or Clob object.

Verify that your environment meets the requirements listed in Table before you configure the driver for Kerberos authentication. The User property provides the user Sqlserverdrivwr.

The client must be administered by the same domain controller that administers the database server. The default is noEncryption.

Connecting to a Database

Explicit transaction cleanup provides more control than transaction timeout over when distributed transactions are cleaned up. If you want the driver to use a wqlserver of user credentials other than the operating system user name and password, include code in your sqlservrdriver to obtain and pass a javax. If the database type is not an n-type, the driver converts the data to the character encoding defined by the parameter’s collation and sends the data to the server in that character encoding.


To improve performance, you slserver disable long data caching if your application retrieves columns in the order in which they are defined in the result set. Determines whether the driver uses its internal conversion algorithm or the JVM conversion algorithm when converting double or float values to string values.

Specifies how the driver describes String stored procedure output parameters to the database. The SQL Server driver can use client-side cursors or server-side cursors to support updatable result sets.

Typically, the Direct method performs better than the Cursor method. The driver ignores any user ID or password specified.

If the values do not match, the connection fails and the driver sqlsrverdriver an exception. The setFetchSize method can be used to control the number of rows that are retrieved for each request when forward-only result sets are returned. See Using the AuthenticationMethod Property for more information about setting a value for this property.

This property is optional and provides additional security against man-in-the-middle MITM attacks by ensuring that the server the driver is connecting to is the server that was requested.

For example, many application servers or Web servers act on behalf of the client user logged on the machine on which the application is running, rather than the server user.
