Followup to "Row generators, part 2"

$

My last post generated many excellent comments, here and on twitter.

As several people pointed out in the comments, using CONNECT BY to generate a large number of rows is memory intensive, and may fail with errors like "ORA-30009: Not enough memory for CONNECT BY operation" or "ORA-04030: out of process memory". One improvement that gets around this is to use Cartesian join on two or more 1000-row CONNECT BY sources, as Tanel Poder suggests in this 2008 blog post:

set timing on
set autot traceonly

with 
r1 as (select level from dual connect by level <= 100),
r2 as (select level from dual connect by level <= 100),
r3 as (select level from dual connect by level <= 1000)
select rownum from r1, r2, r3
;

10000000 rows selected.

Elapsed: 00:00:06.03

Statistics
----------------------------------------------------------
          1  recursive calls
          0  db block gets
          0  consistent gets
          0  physical reads
          0  redo size
   69281273  bytes sent via SQL*Net to client
      22513  bytes received via SQL*Net from client
       2001  SQL*Net roundtrips to/from client
          5  sorts (memory)
          0  sorts (disk)
   10000000  rows processed

Jonathan Lewis suggested increasing arraysize in sql*plus to decrease the time spent in SQL*Net traffic. The default is 15, range from 1 to 5000:

set arrays 1
/
10000000 rows selected.

Elapsed: 00:09:56.88

set arraysize 15
/

10000000 rows selected.

Elapsed: 00:01:27.09

set arraysize 5000
/
10000000 rows selected.

Elapsed: 00:00:06.23

Sayan Malakshinov suggested this variation, which uses hash join instead of the outermost merge join cartesian:

set autot traceonly
set arrays 5000
with 
r1 as (select 1 as x  from dual connect by level <= 100),
r2 as (select 1 as x  from dual connect by level <= 100),
r3 as (select 1 as x  from dual connect by level <= 1000)
select rownum from r1, r2, r3
where r1.x = r2.x and r1.x=r3.x and r1.x=r2.x
;

10000000 rows selected.

Elapsed: 00:00:06.07

Finally, for a comprehensive treatment of row generators, including pipelined functions and MODEL clause, several people pointed to this article by Adrian Billington.

Announcing Java SE 8 Update 40

$
0
0
Improved performance, scalability and administration in Java SE 8 Update 40 will allow Java developers to innovate faster and improve application services. Here are some features and changes including JavaFX updates: 

JVM Reaction to Memory Pressure: “Memory pressure” is a property that represents the total memory usage (RAM) on the system. This new feature can be leveraged to reduce the amount of memory used on a system where multiple JVMs are deployed and control the amount of memory designated to be consumed by each JVM, avoiding Out of Memory Errors (OOMEs) from occurring.

Improvements to the native packager: Enables developers to create native-feel applications that do not require clients to have an existing Java Runtime installed. These self-contained applications can then be deployed into areas like the Mac app store. The application developer has full control over the runtime and application entry points.

Ability to modernize the JavaFX stack on Mac OS X: The JavaFX media stack has been ported on Mac OS X® from QTKit and Quicktime, which have been deprecated, to the newer AVFoundation framework. With this, developers using the JavaFX media stack can now gain Mac App Store acceptance and have the opportunity to have their applications released on the Mac App Store. 

Nashorn Support: Numerous Nashorn optimizations including support for dynamic languages are incorporated into this release. Also added is a Nashorn Class Filter, which provides fine-grained control over access to Java classes from JavaScript code via a new filtering interface. 

New Time Zone Date Updater Tool: This tool can consume the ‘raw’ time zone data (tzdata) rules from the IANA time zone registry database and convert those to the necessary format required by the JRE. This provides users with the ability to immediately update the JDK/JRE time zone rules with the latest updates from IANA.

JDK 8u40 Released!

$
0
0

JDK 8u40 has been released and is available from the Java SE Downloads page. See the JDK 8u40 Update Release Notes for details.

Java Tutorial Updates

The Java Tutorial has been updated to include a new lesson in the Deployment trail that describes how to use the Java packaging tools to generate self-contained applications. Self-contained applications are Java applications that are bundled with the JRE that is needed to run. These applications are installed on a user's local drive and launched in the same way as native applications. See Deploying Self-Contained Applications for more information.

JDK Tools Enhancements

JDK 8u40 contains many tools enhancements. See Tools Enhancements in JDK 8 for details.

JavaFX Enhancements

Starting with the JDK 8u40 release, JavaFX controls are enhanced to support assistive technologies, meaning that JavaFX controls are now accessible. In addition, a public API is provided to allow developers to write their own accessible controls.

Accessibility support is provided on Windows and Mac OS X platforms and includes:

  • Support for reading JavaFX controls by a screen reader
  • JavaFX controls are traversable using the keyboard
  • Support for a special high-contrast mode that makes controls more visible to users.

JDK 8u40 also includes new JavaFX UI controls; a spinner control, formatted-text support, and a standard set of alert dialogs.

Spinner Control

A Spinner is a single line text field that lets the user select a number or an object value from an ordered sequence. See javafx.scene.control.Spinner class for more information.

Formatted Text

A new TextFormatter class provides text formatting capablity for subclasses of TextInputControl (for example, TextField and TextArea). See javafx.scene.control.TextFormatter class for more information.

Dialogs

The Dialog class allows applications to create their own custom dialogs. In addition, an an Alert class is also provided, that extends Dialog, and provides support for a number of pre-built dialog types that can be easily shown to users to prompt for a response. See javafx.scene.control.Dialog, javafx.scene.control.Alert, javafx.scene.control.TextInputDialog, and javafx.scene.control.ChoiceDialog classes for more information.

Commercial Features

Application Class Data Sharing (AppCDS):

Application Class Data Sharing (AppCDS) extends CDS to enable you to place classes from the standard extensions directories and the application class path in the shared archive. This is a commercial feature and is no longer considered experimental (contrary to what is specified in the java tool documentation). See the -XX:+UseAppCDS option in the java launcher tool page.

Cooperative Memory Management

Starting with JDK 8u40, the notion of "memory pressure" has been added to the JDK. Memory pressure is a property that represents the total memory usage (RAM) on the system. The higher the memory pressure, the closer the system is to running out of memory.

As a reaction to increased memory pressure, the JDK will try to reduce its memory usage. This is mainly done by reducing the Java heap size. The actions the JDK will take to reduce memory usage may lead to reduced performance. This is an intentional choice.

The pressure level is provided by the application through a JMX MXBean using a scale from 0 (no pressure) to 10 (almost out of memory). To enable this feature, the jdk.management.cmm.SystemResourcePressureMXBean should be registered. The memory pressure is then set using the "MemoryPressure" attribute.

A new command line flag -XX:MemoryRestriction that takes one of the arguments 'none', 'low', 'medium', or 'high', is also available. This flag will set the initial pressure in the JDK and will work also in cases where the MXBean is not registered.

Cooperative Memory Management requires the G1 GC (-XX:+UseG1GC). This feature is not compatible with the flag -XX:+ExplicitGCInvokesConcurrent.

New Commercial Flags

Two new VM options are now available for commercial license holders:

  • -XX:+ResourceManagement
  • -XX:ResourceManagementSampleInterval=value (milliseconds)

For more information, see the javatool page.

New MSI Installer Documentation

The Microsoft Windows Installer (MSI) Enterprise JRE Installer Guide is now available. The MSI Enterprise JRE Installer requires a commercial license for use in production. To learn more about commercial features and how to enable them, visit http://www.oracle.com/technetwork/java/javaseproducts.

Java Flight Recorder(JFR) Enhancements

It is now possible to enable Java Flight Recorder at runtime. For details, see the Java Flight Recorder Runtime Guide. Java Flight Recorder requires a commercial license for use in production. To learn more about commercial features and how to enable them, visit http://www.oracle.com/technetwork/java/javaseproducts.

Does Your Company Recognize Your Online Identity - Anywhere, Anytime?

Our mobile IDs travel with us to work, back home, and on the road. Businesses are learning to cope.

by Lynn Sampson

Like most aspiring writers, I loved going to the library as a kid. I had a library card as soon as I was old enough to sign my name—creased and frayed from overuse, tucked inside my mom’s wallet. Mom and I handed our cards to the librarian at each visit, and she looked up our names in the library register and compared our signatures to the ones on our cards.

This old-fashioned, analog ID system was around for a long time. It was less than 10 years ago that my local library replaced paper cards with plastic ones, with a photo ID and a magnetic stripe.

Today, analog IDs have gone the way of cursive script. Nearly all IDs are digital. Since the rise of the internet, our banks, employers, and apps ask us for a plethora of user names, passwords, and security questions to prove that we are who we say we are.

This is a nuisance for absent-minded consumers who make frequent use of the “Forgot My Password” button. But it’s an even bigger problem for the companies and employers that we do business with.

67% of Fortune 500 companies connect with customers via mobile app

“Mobile has become the platform of choice for everything from work to vacationing,” said Naresh Persaud, senior director of security product marketing at Oracle. “That adds a layer of complexity to identity management that most organizations haven’t had to deal with before.”

Consider the way we work. “Many companies have salespeople who travel constantly. They use their tablets all the time, and they want to log into their applications, track their deals, check and assign new leads. They like the mobile experience because it’s familiar and easy to navigate,” Persaud said.

What’s not so easy is provisioning all those mobile devices for a corporate network—especially as more and more of us use our personal devices for work.

89% use personal devices for work purposes

Adding further complexity to the mix, a growing volume of marketing, selling, and hiring is done via social channels like Facebook, Twitter, and LinkedIn. “Many of us need social tools integrated into our mobile identities,” Persaud continued. For example, one B2B company tracks new leads coming in from marketing campaigns and then checks the prospect’s ID on LinkedIn. If the sales manager finds a rep who is already part of the prospect’s LinkedIn network, he’ll assign the lead to that rep, using existing relationships to gain an introduction.

And it’s not just customers or employees who companies must think about. “At some companies, like online music providers, the product itself is digital.” This is becoming more common as the “sharing economy” (driven by apps like Uber and Airbnb) takes flight. This means keeping track of which user has access to which products and services. “We’ve entered a world of ‘digital abundance,’ where our mobile ID becomes the currency of entitlement,” Persaud said.

What does it take to manage our mobile identities? How do companies give employees and customers access to all their apps, systems, and products from a multitude of devices?

Companies need to establish policies, technologies, and best practices to manage and audit the use of mobile devices. Mobile should be an integral part of your company’s larger security and identity strategy.

“You need an integrated platform that provisions access to data and systems, manages the identities of people, and authenticates devices,” Persaud explained. “Integrated” is the key ingredient when it comes to managing mobile identities. Using separate security solutions for data, devices, and people makes it more complicated for customers and employees to get access to the tools they need. Plus, a single identity for each user—no matter which device they’re on—can help you maximize conversion and revenue.

“A great example of this is Beachbody,” Persaud said. Beachbody provides home fitness products and creates a community for members trying to reach their physical fitness goals. “Instead of physical locations, Beachbody delivers products and services via the web and mobile devices.” To connect with millions of customers and thousands of fitness coaches, Beachbody needed to digitize identity and do it securely across multiple channels. “Mobile was perhaps the most important part of their identity management project,” Persaud added, “because it’s become the platform of choice for consumers.”

Our mobile identities are somewhat akin to DNA—unique, evolving, and hugely complicated. Someday, our DNA might actually be the key that we use to access all technology and services, from pension checks to downloaded music. Until that happens, though, companies need to work with mobile identities. That means working with an integrated security suite that includes mobile as a consideration equal to data and people.

Announcing Coherence for the Java Cloud Service

$
0
0

Today we are excited to announce a major product innovation - Oracle Coherence is now available as a feature of the Java Cloud Service (JCS). Effective immediately, users of JCS can use our cloud tooling to optionally set up Coherence within JCS.

Flexibility is a key part of the solution. You can either select an initial capacity for the Coherence data tier:

Or use the "Advanced" option to have full control over the number of virtual machines you want for Coherence, the number of managed Coherence servers per virtual machine, and the heap size of each managed server: 

The WebLogic Management Framework is used under the covers allowing you, the user to develop, deploy, manage and monitor your applications via Managed Coherence Servers.

Because the same cloud tooling creates both WebLogic and Coherence, the experience of using the two together in our cloud is a fully integrated and seamless service. As is standard with JCS, you can patch Coherence as you please in an automated rolling fashion. Backups and restores are fully coordinated with the rest of the stack.

Common reasons for using Coherence:

  • Offload and protect shared cloud services and databases
  • Deliver real-time data to cloud applications
  • Provide transparency and high availability in the cloud's data grid tier

When running a WebLogic 12.1.3+ environment in the Java Cloud Service you have access to all the Coherence cloud tooling. For Java Cloud Service Enterprise Edition 11g with Coherence, you can manually create your own Coherence cluster.

Over the coming year, we plan to release a number of Coherence-related data grid and caching services. Stay tuned for more details.
