December 6, 2013 by Leave a comment 

The newest Oracle Exadata Database Machine X4 is available for ordering! After I reviewed in my last article some hardware insights of Oracle Exadata X4, let’s talk about the software options, improvements and new features that will be available soon in the new Exadata.

If you order an Oracle Exadat X4 system you can choose between two Oracle database versions: 11g or 12c.  The relevant database version will be pre-installed by Oracle Advanced Customer Support (ACS) Services with additional Grid infrastructure software including Oracle ASM and RAC. Prerequisite is that you have enough database and RAC licenses.

Oracle Exadata X4 Machine will be delivered with the new Exadata software version that provides the following major capabilities:

– Automatic Flash compression on X3 and X4 systems
– Improved support for consolidation of multiple databases
– Many management improvements
– Many robustness and availability improvements

See below some major new Exadata software featurues that are going to be incorporated to the new X4 machines.

Oracle Exadata X4 database machine – hardware insights

November 30, 2013 by Leave a comment 

The last version of Oracle Exadata Database Machine X3 was announced shortly before the Oracle Open World 2012 Conference. It was great to see at that time more power for the same price, 1/8 rack option and the new Platinum Services on the top. General availability date for the new Oracle Exadata X4-2 is not finally communicated at the moment but I guess it will be released already early in 2014. Below I give some insights of the expected hardware changes  compared to Exadata X3.

As with the previous version Exadata X4 will provide large performance and capacity increases with no changes in Exadata Hardware or Software Prices. Increased CPU cores may require more database licenses though.

Oracle database High Availability – Exadata and Oracle 12c

November 1, 2013 by Leave a comment 

Going through different approaches in building Oracle database systems in best High Availability (HA) practices in my previous articles we went through following important topics:
understanding High Availability (HA) and SLA requirements; reviewing database Availability Levels based on industry standards; building High Availably (HA) database systems based on Oracle ASM, Clusterware and Cold Failover cluster; Oracle Data Guard, Standby and RAC; Extended RAC and MAA. Basically we finished everything but I wanted to give two more extras, which is Oracle Exadata and Oracle 12c High Availability features.

The integration of Oracle Maximum Availability Architecture (MAA) best practices with Oracle Exadata Database Machine (Exadata MAA) provides the most comprehensive Oracle High Availability (HA) solution available for the Oracle database. Exadata MAA is very matured and pre-optimized, pre-configured, integrated system of software, servers, storage and MAA configuration best practices that comes ready to implement the highest database High Availability.

Exadata MAA architecture shown in figure below is designed to tolerate unplanned outages of all types, providing both High Availability (HA) and data protection. Exadata MAA also minimizes planned downtime by performing maintenance in a rolling fashion.

With Oracle Exadata X3 machine version 3 that was announced just before Oracle Open World 2012, Oracle extended the Exadata resources, features and the Support model that all improved the overall system High Availability (HA). The new Oracle Exadata X4 is going to be released in 2014.
