Optimizing Oracle Data Guard with BIG-IP WOM

Oracle Data Guard

Oracle Data Guard enables you to configure master databases and replication target databases. When a transaction flows into the master database, Data Guard automatically replicates it to the target as a complete transaction, guaranteeing the integrity of your copy throughout the transaction. Data Guard is designed to perform constant updates whether the database is a local copy—to ensure rapid recovery from a lost database server—or a remote copy—to help with backup or disaster recovery.

When the replication target is a remote system, the complexity and volume of data being replicated can fill up the WAN connection, slow the completion of replication transactions, and create a situation where sudden downtime could potentially leave your target database out of synch with the original because of network congestion. The higher the latency and packet loss between data centers, the more performance degrades.

BIG-IP WOM can help you improve the security, reliability, and effectiveness of your replication by reducing the amount of data that is transferred over the WAN; encrypting that data without having to add the burden of encryption to your database server; and optimizing the connection between the two databases. Since BIG-IP WOM is a stand-alone appliance, placing one device at each end of your connection will improve security and performance of all Data Guard activity passing over that connection—even across multiple hosts and databases. And with rate shaping built into the BIG-IP product, performance on the WAN link is guaranteed, and it ensures that Data Guard receives the necessary bandwidth. Combined, all of the powerful features of BIG-IP WOM increasethe performance and reliability of your Data Guard replication over the WAN.

Whether you are looking to use Data Guard over long distances, to defer the cost of upgrading your WAN connection, to secure your Data Guard transactions, or to recover space on your WAN connection for use by other applications, BIG-IP WOM can help.

Solution

BIG-IP WOM enables customers to:

• Accelerate data replication/backup across the WAN
• Mitigate the effects of latency, packet loss, and congested networks
