If connection retry is enabled, the client application can continue to retry the connection until a connection is successfully accepted by the server. Connection retry can be an important strategy for system recovery after a power failure. Connection failover allows an application to connect to an alternate, or backup, database server if the primary database server is unavailable, ensuring that the data on which your critical ODBC applications depend is always available.

How is this possible? Not only do these new drivers remove a communication layer, they can control which calls are made to the DBMS, and these calls can be optimized to just those required for accessing data.Ĭonnection failover and connection retry are two useful features that are available in the following DataDirect Connect® for ODBC drivers: DB2 Wire Protocol, Informix Wire Protocol, Oracle Wire Protocol, Oracle, SQL Server Wire Protocol (UNIX only), and Sybase Wire Protocol. This dramatically reduces overhead on support and upgrades, and DLL conflicts are virtually eliminated because all of the drivers are from the same vendor.īecause wire protocol drivers eliminate a layer of translation between the application and the DBMS, the rate of data access speed is increased so much that independent tests have proven that wire protocol drivers actually outperform applications coded natively. This leads to increased support activities and complex upgrades.By contrast, only one wire protocol ODBC driver per database brand is required.

Because different client libraries are required to be installed for each version or database technology, each one consumes memory and CPU time. This is especially true where multiple versions of a database or multiple database technologies need to be accessed. The larger footprint with the traditional ODBC architecture can directly impact the performance and stability of a system or network. Using wire protocol drivers also results in a smaller footprint for the application. Using wire protocol ODBC drivers reduces the complexity of deploying ODBC applications by one half, compared to the traditional 2-step ODBC drivers that leverage “classic” ODBC architecture. If an application needs to access three databases that each has their own native API, the benefit is even more obvious.

DataDirect wire protocol ODBC drivers contain all the software needed to access the database, eliminating the prerequisite of having the client libraries loaded and configured on every computer prior to using the ODBC driver. Wire protocol architecture is what allows DataDirect ODBC drivers to deliver the fastest, most scalable and secure application connections to relational databases.īenefits of Using an ODBC Wire Protocol DriverĬompanies deploying applications that use DataDirect wire protocol drivers will find them much easier to implement. The unique wire protocol design of DataDirect’s ODBC driver directly connects directly to the database via TCP/IP and thus eliminates the need for database client software and libraries, which greatly simplifies installation and administration and dramatically improves performance. Here is more information: DataDirect offers the industry’s only suite of wire protocol ODBC drivers for Oracle, SQL Server, DB2, Sybase, and Informix.
