" We Tune the heartbeat of your applications. "

Internet and Global Enterprise technologies have enabled worldwide collaboration and information sharing by expanding the reach of applications throughout organizations and communities. Users and customers are worldwide. This requires uninterrupted access to applications and data. To achieve such a goal organizations must designed IT Infrastructure for Maximum Availability and High Performance. SamaraTech’s specialized High Availability Team accomplishes this objective.

• Maximum Availability and Scalability

Maximum Availability Architectures (MAA) include appropriate redundancy, protection from outages, robust security and achieve designed performance parameters. Organizations can readily manage these architectures and scale them to meet new requirements.

SamaraTech builds IT Infrastructures that achieve MAA standards and objectives by using Oracle MAA components and Industry best practices.



• Oracle Real Application Clusters (RAC)

SamaraTech has unparalleled experience designing and implementing RAC. Our approach to RAC goes beyond the database and includes proven architecture design for the Operating System, servers, network interconnects and the storage layer. Our best practices implementation of Oracle Grid Control for proactive monitoring paired with Oracle Data Guard for Disaster Recovery allows you to further minimize the risk of data loss and database downtime.

This architecture involves identically configured primary and secondary sites. The primary site contains multiple application servers and a production database using Oracle Real Application Clusters (RAC) to protect from host and instance failures. The secondary site also contains similarly configured application servers, and a physical standby database kept synchronized with the primary database by Oracle Data Guard. Clients are initially routed to the primary site. If a severe outage affects the primary site, Data Guard quickly fails over the production database role to the standby database- providing maximum return-on-investment along with data protection and availability.



In addition, SamaraTech provides best practices based implementations of:

• Oracle Data Guard
• Oracle RMAN for Backup and Recovery
• Oracle Streams for Replication

• Oracle Enterprise Manager Grid Control

Build a robust Grid computing infrastructure with guidance and implementation services from SamaraTech’s Oracle experts. This allows detailed monitoring and reporting of any Oracle Server product.

The Benefits includes

• Proactive warnings about impending database and operating system issues
• Increased system uptime and performance mitigates risk
• Both real-time and historical reporting on system performance and uptime – (this is a key feature of Grid Control as compared to Oracle Enterprise Manager which only reports on real-time statistics)
• Scheduling function can be used to execute both database- and operating system-level jobs
• Database manipulation tasks (expand a tablespace, fail over to a standby instance, etc) can be done via the Grid Control console

SamaraTech offers following services for Oracle Enterprise Manager Grid Control

• Prepare infrastructure hosts for Grid Control rollout
• Install the Oracle management repository, service, and agents
• Select the Grid Control installation options that fit organization needs
• Discover and manage host, database, and application server targets
• Set target metrics and policies according to best practices
• Optimize performance and availability of Grid Control framework
• Secure the Grid Control framework to protect data transmitted between components

• Oracle Configuration and Performance review

SamaraTech’s database review provides a wealth of information regarding the performance and health of your Oracle database and application platform. We identify critical issues and recommend configuration, standardization and tuning strategies that enhance performance, increase productivity, and lower your investment in hardware and software. SamaraTech’s performance optimization services consider all layers of technology that contribute to an optimal database platform. Depending on your needs, we can consider some or all of the following:

• Oracle Best practices and standards.
• Performance metrics and configuration parameters such as hit ratio, SGA size, database extents, memory usage and data caching.
• Advanced configurations for data caching, load balancing, extended scalability and extreme performance.
• Capacity planning based on correlation between business objectives, business expectations and financial expenditure planning.
• Application integration considerations for optimal manageability and performance.

• Systems Migration and Upgrade

Depending on your individual business requirements, we have the experience and expertise required to migrate your existing database(s) to all Oracle platforms including Oracle 9i, Oracle 10g and Oracle 11g.Working together, SamaraTech and your IT staff can to ensure a successful migration. While your staff has expertise in your legacy systems’ database, code, and business rules, SamaraTech has the expertise in the target platform, which is critical to success.

A database migration is more than a simple mapping of data. It requires an understanding of field-level idiosyncrasies, indexing, parameter-settings and design. A migration of an application can take on several different forms; from porting to a new database, to a re-write in a different development tool. As experts in Oracle technology (database, tools and middle-tier), SamaraTech ensures that every detail is orchestrated.
