RAC

Enterprises today require 99.9+% availability for their business applications. Immediate response times and trouble free operation are expected. An Oracle Real Application Cluster (RAC) implementation will provide a highly available and scalable environment.

With Oracle RAC, multiple database instances that each run on a physically separate node share access the same database (files) residing on common, resilient storage. If any node goes down, the database and application will continue without intervention. Oracle RAC can also scale by adding nodes, balancing the load across the cluster and even allow the provisioning of processors on demand.

Though generally a "high end" solution, Oracle RAC is also finding a place in the enterprise in smaller systems when absolute redundancy is required, but budgets are tight. Oracle Database Standard Edition includes RAC at no additional charge and can be a fit.

We can support you in your quest for high availability and/or scalability by providing expertise in the design and implementation of an optimal and cost effective Oracle RAC solution.

We have experience with file-based protocols (NAS: 11g Direct NFS, CIFS), Block-based protocols (SAN/iSAN: Fibre Channel, iSCSI) and High-speed transport implementations on a variety of hardware platforms and operating systems.

All components of a carefully executed RAC architecture can be provided including server (OS) preparation, installation, scripting, network setup, Oracle Cluster Ready Services software (CRS), and Automatic Storage Management (ASM) as appropriate.

Data Guard

If your business is seeking a cost-effective data protection and disaster recovery solution, Oracle Data Guard is the most effective and comprehensive solution available today. Oracle Data Guard will protect your Oracle Database against planned and unplanned downtimes by creating physical and/or logical standby databases.

Oracle Data Guard is a comprehensive management, monitoring, and automation software infrastructure that creates, maintains, and monitors one or more standby databases to protect enterprise data from failures, disasters, errors, and corruptions.

Oracle Data Guard maintains these standby databases as “transactionally consistent" copies of the primary database. Standby databases (up to nine) can optionally be located at geographically remote sites miles away from your production data center. If for any reason your business’s critical production database becomes unavailable, Oracle Data Guard can switch any standby database to the primary role, minimizing downtime associated with the outage and preventing any data loss.

We provide solution support for enterprise ready logical and physical standby databases using Oracle Data Guard.

Recovery Manager (RMAN)

RMAN is Oracle's recommended database backup toolset. It offers many advantages over user-managed backups and is an integral part of any Oracle maximum availability architecture.

RMAN uses server sessions to perform backup and recovery operations and stores metadata about backups in a repository. RMAN offers many advantages over typical user-managed backup methods, such as the ability to do online database backups without placing tablespaces in backup mode; support for incremental backups; data block integrity checks during backup and restore operations; and the ability to test backups and restores without actually performing the operation. RMAN automates all backup and recovery for your Oracle database.

For your enterprise, we provide services to design and assist in your migration to RMAN. We provide mentoring, standards, scripting and testing of proven backup and recovery strategies to meet the availability goals of your enterprise.

We can help you greatly reduce the footprint of any application while maintaining and even enhancing enterprise and service oriented integration.

These migrations are far less complex than the systems they replace and can provide much greater availability and reliability. Development costs, maintenance costs, hardware costs, license costs are all on the table for reduction in the architected solution.

We are often the consulting firm of choice as a sub-contractor by the larger integrators when risks exist in the form of cutting edge database technologies, large data conversions and other complex business problems.

Linsonic was a beta site for versions 10g, 10gR2 and 11gR1 of the Oracle database. We have ex-Oracle staff and maintain a very close relationship with Oracle support and development.

Even if you are not an Oracle shop, we can show you opportunities that exploit technologies only available in Oracle and yet are very cost competitive with Microsoft SQL Server and others. Proper small licensing strategies along with solutions that reduce or even eliminate database administration through "embedding" can open many possibilities never before considered.

We have been very successful in the migration of many COBOL, client server and other legacy system architectures to web based solutions. These legacy systems often are difficult to maintain, lack sufficient documentation and/or are on the verge of collapse. With a controlled scope, these robust solutions have been delivered very quickly and sometimes at fixed cost.

Legislative Systems

We have considerable expertise in schema based conversion and storage of native XML documents in the database using Oracle XML DB. This includes high performance fragment level search, retrieval and manipulation of very large documents. We can also provide support for large document repositories support using the content management features of XMLDB.

We are of the belief that Oracle Application Express (Apex) has unlimited capability.

It has now achieved maturity, sustained growth and continues exceptional momentum. Mission critical success stories abound (including our own).

Because it's a free component in the database, it has ironically, been overlooked in the past. That is changing (because it's free, the sales force out there has had little interest in it's promotion. Oracle's own commitment however has continued to strengthen).

What it can do is eliminate architecture expense better than any other technology we know of. In nearly all implementations, it eliminates the middle tier completely. Significant hardware, license, development, administration costs are gone.

For any system that was created more than a few years ago and needs a web-based migration, this simplified approach is easily up to the task and the savings can be immense.
