Do your systems require constant accessibility?

If so, then you know that application failover is an important function for automatically and transparently redirecting requests to an alternate server in the case of a failed or down system.

What you may not know is that the database driver you choose for your software architecture can manage application failover for you.

This means you won't have to implement time-consuming proprietary code in the application or costly server configurations provided by the database vendors such as Oracle RAC.

For example, if an online brokerage user was in the midst of reviewing a list of large stock trades and performing a series of tasks relating to each stock trade, it would be very problematic if the database containing the stock trade history becomes unavailable. If the application is not able to failover and restore the state of the transaction, the user would have to go to a great deal of trouble to restart the transaction activity.

With the DataDirect driver managing failover support for the application, if a database server becomes unavailable while the trade list is being processed, the DataDirect driver will transparently failover the transaction to an alternate server and reposition the state of the transaction so that the user can continue processing the next stock trade.

DataDirect application failover enables you to:

  • Guarantee application reliability and data integrity
  • Manage failover without additional coding or expensive server dependencies
  • Provide a consistent failover approach regardless of database server or application environment

Implementing high-quality, reliable application failover via DataDirect translates into these benefits for the business: increased revenue and customer satisfaction.
