Oracle Replication – Streams, Data Guard, & RAC:

 Certified Oracle engineers at our Oracle database company have deep experience in managing Oracle Replication from 8i to 12c handling various types of Oracle Replication such as Streams, Advanced Replication, Data Guard, and Oracle Real Application Clusters (RAC). Data availability is an important factor in the success of any business. In a distributed environment, Oracle Streams improves data availability and accessibility by sharing and replicating information to multiple sites quickly and reliably.
Oracle Streams was introduced in Oracle 9i and is used to perform data replication, data warehouse transformation, and messaging. Created as a disaster recovery solution, Oracle Data Guard is also a solution for High Availability. It can be used to replicate and maintain production databases to alleviate reporting job traffic on the server. Our Oracle database company will configure Data Guard for real-time consistency between the production database and one to as many as nine standby databases or, delayed by a set time to allow the standby to become a snapshot standby.
Data Guard becomes especially useful for testing and rolling upgrades and can be configured as either a physical (Redo-Apply) or logical (SQL-Apply). Each has its advantages and inherent flexibility. Oracle Real Application Clusters (RAC) is an option of Oracle DBA services. It is a cluster database with a shared cache architecture that overcomes the limitations of traditional shared-nothing and shared-disk approaches to provide highly scalable and available DBA services for all business applications.
Oracle RAC is a key component of Oracle enterprise grid architecture. Most users of Oracle RAC employ a two-node cluster to insure always available service to its user community. The two-node configuration offers the flexibility needed to perform maintenance, upgrades, and patching without interfering with user activity.

Oracle Backup and Recovery:

Does your backup strategy match your business needs? Are you backing up frequently enough to prevent a large data loss? Our database services company can help you design a backup and recovery strategy that matches your needs to protect your data as well as provide you with recovery with minimum downtime. Our Oracle database company can assist with the implementation of your backup and recovery strategy using various methods including Export/Import, Cold or Off-line Backups, Hot or On-line, and Recovery Manager (RMAN). 

It is often advisable to use more than one of these methods to back up your database. Does your organization also back up all required parameter files, software libraries, password files, etc? Your organization may also need to back up archived log files if your database is in ARCHIVELOG mode.
Our oracle dba support services team can work with you to design, plan, implement, and test all the backup and recovery strategies you need to have in place.
