HA Database Clusters(RAC)
High availability planning involves identifying which databases need to be continuously operational no matter what happens. The next step is choosing technologies that will protect your data and allow it to remain online with little to no downtime.
Aarisha's data experts will consider all your requirements - acceptable downtime, critical applications, recovery time targets, service level commitments and provide recommendations to ensure your data is available when and where it's needed. We can help your staff implement the technologies or do it for you. Either way, you will have a solution that is customized to your business needs.
Having high availability in place allows your databases to remain operational in case of failure, whether it's a hardware issue or within your data center. Your high availability strategy allows your databases to remain online during many kinds of planned maintenance. Aarisha's expertise in high availability planning and technologies means your data can be available within only minutes, seconds, or with zero downtime.
Oracle High Availability (RAC) Implementation
Many businesses today require 99.99% availability for their enterprise applications and they expect immediate response times. An Oracle Real Application Cluster (RAC) environment provides this highly available, high performing, scalable environment. [High Availability (RAC) Implementation]
With Oracle RAC, multiple instances running on multiple nodes can access the same database residing on shared storage. If one node goes down, the database and application will continue to run. If the performance is an issue, another node can be added to the cluster and the application can be load balanced across all of the available nodes.
Whether the goal is high availability, scalability or ease of maintenance, the team of Oracle consultants at Aarisha Inc. provides the expert assistance to identify your needs, and then design and implement your optimal RAC solution. Our consultants have worked with many High Availability technology solutions: Oracle 9i, 10G,11G and 12C RAC, Oracle Parallel Server, Veritas Cluster Volume Manager and hardware clustering on Dell, Sun, HP, DEC and Microsoft platforms. We provide "best practice" RAC implementations at the database level and the operating system level.
Some of our RAC best practice implementation services include:
