Oracle DB 12c runs best on Sparc

Oracle's vision of Engineered Systems is transforming into reality with every new product that Oracle is launching. Oracle Database 12c, which was launched in 2013, is an example on how Oracle software is optimized for Oracle Solaris SPARC. Oracle Database 12c is co-engineered with Solaris engineering team and Oracle’s world record SPARC T5 servers have best performance and maximum ROI.

Independent Software Vendors (ISV) who are developing applications using both Oracle DB 12c and Solaris are taking advantage of one core technology, one operating system, one virtualization tool for all the range of SPARC servers. An ISV application can boost its performance, flexibility and security just by using SPARC high numbers of cores and big memory, combined Oracle 12c/Solaris/SPARC multi-tenancy,  zones and LDoms light-weight virtualization technologies, SPARC and Solaris build-in encryption, etc.

Let’s take a look at how all this is translated into technical features. What makes Solaris and SPARC servers the best infrastructure for Oracle 12c enterprise databases?

Morgan Stanley chooses Solaris 11 to run cloud file services

At the EAKC2012 Conference last week in Edinburg, Robert Milkowski, Unix engineer at Morgan Stanley, presented on deploying OpenAFS on Solaris 11. It makes a great proofpoint on how ZFS and DTrace gives a definite advantage to Solaris over Linux to run AFS distributed file system services, the "cloud file system" as Robert calls it in his blog. Robert used ZFS to achieve a 2-3x compression ratio on data and greatly lower the TCA and TCO of the storage subsystem, and DTrace to root-cause scalability bottlenecks and improve performance. As future ideas, Robert is looking at leveraging more Solaris features like Zones, ZFS Dedup, SSD for ZFS, etc.

Gemalto Mobile Payment Platform on Oracle T4

GemaltoGemalto is the world leader in digital security, at the heart of our rapidly evolving digital society. Billions of people worldwide increasingly want the freedom to communicate, travel, shop, bank, entertain and work – anytime, everywhere – in ways that are convenient, enjoyable and secure. Gemalto delivers on their expanding needs for personal mobile services, payment security, identity protection, authenticated online services, cloud computing access, eHealthcare and eGovernment services, modern transportation solutions, and M2M communication.

Gemalto’s solutions for Mobile Financial Services are deployed at over 70 customers worldwide, transforming the way people shop, pay and manage personal finance. In developing markets, Gemalto Mobile Money solutions are helping to remove the barriers to financial access for the unbanked and under-served, by turning any mobile device into a payment and banking instrument.

In recent benchmarks by our Oracle ISVe Labs, the Gemalto Mobile Payment Platform demonstrated outstanding performance and scalability using the new T4-based Oracle Sun machines running Solaris 11.

Using a clustered environment on a mid-range 2x2.85GHz T4-2 Server (16 cores total, 128GB memory) for the application tier, and an additional dedicated Intel-based (2x3.2GHz Intel-Xeon X4200) Oracle database server, the platform processed more than 1,000 transactions per second, limited only by database capacity --higher performance was easily achievable with a stronger database server. Near linear scalability was observed by increasing the number of application software components in the cluster. These results show an increase of nearly 300% in processing power and capacity on the new T4-based servers relative to the previous generation of Oracle Sun CMT servers, and for a comparable price.

T4-2

In the fast-evolving Mobile Payment market, it is crucial that the underlying technology seamlessly supports Service Providers as the customer-base ramps up, use cases evolve and new services are launched. These benchmark results demonstrate that the Gemalto Mobile Payment Platform is designed to meet the needs of any deployment scale, whether targeting 5 or 100 million subscribers.

Oracle Solaris 11 DTrace technology helped to pinpoint performance issues and tune the system accordingly to achieve optimal computation resources utilization.

Investigating Memory Leaks with Dtrace

This article shows a real case of DTrace framework usage to detect undeleted objects in a C++ application running on Solaris 10. In this case context, undeleted objects refer to temporary business objects that are explicitly created, with the new() operator, but never destroyed. This behavior, comparable in its effects to the so-called memory leak1, may lead to a significant unwanted increase in memory usage and cause paging activity on the system, or even generate new objects creation failures with applications which create objects iteratively.

Since the non-deletion of these business objects is not the result of bad pointers but rather of an incorrect cache management in the application, specialized memory-leaks tracking tools which look after allocated memory chunks-pointers inconsistencies do not detect this type of undeleted objects. For instance, Oracle Solaris Discovery tool2 or Oracle Solaris libumem audit facility3, as well as Rational Purify or gdb are ineffective in this situation4.

A new tool based on DTrace and perl scripts was developed to address this specific need and is usable with all programs that have iterative objects creation and deletion patterns similar to our case described below. The tool requires no binary change and is easy to use. It has demonstrated its efficiency at a customer site on a pre-production system in finding the leak in a couple of minutes, where the traditional methods failed after days of investigations.
