GeoTools Demo Embedded in an Application Framework via Maven

- by Geertjan

GeoTools 8.4 was very recently released, according to its active blog, and to celebrate here's a starting point for working with GeoTools on the NetBeans Platform: The sources of the above are below, as a Maven project, so this project can be used in any IDE or command line: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/tutorials/geospatial/geotools/MyGeospatialSystem Though quite dated, the GeoTools NetBeans Quick Start is very helpful, especially since it used Maven too, but not the NetBeans Platform, unlike the above sample. From the point of view of NetBeans Platform developers, the GeoTools JMapPane class is very useful, providing the integration point between GeoTools and the rest of the NetBeans Platform application. Being integrated into the NetBeans Platform means that a host of standard features are now available to the GeoTools features, e.g., print functionality, which only requires a runtime dependency on the NetBeans Print API, together with the "print.printable" client property put into constructor of the TopComponent: By the way, I've spent some time now and again being confused about the difference between GeoTools and GeoToolkit. Here's an interesting starting point to beginning to understand the differences and history between them. Soon I'd like to have an example similar for the above for GeoToolkit.

Basic Puppet installation with Solaris 11.2 beta

- by user13366125

At the recent announcement we talked a lot about the Puppet integration. But how do you set it up? I want to show this in this blog entry. However this example i'm using is even useful in practice. Due to the extremely low overhead of zones i'm frequently seeing really large numbers of zones on a single system. Changing /etc/hosts or changing an SMF service property on 3 systems is not that hard. Doing it on a system with 500 zones is ... let say it diplomatic ... a job you give to someone you want to punish. Puppet can help in this case making of managing the configuration and to ease the distribution. You describe the changes you want to make in a file or set of file called manifest in the Puppet world and then roll them out to your servers, no matter if they are virtual or physical. A warning at first: Puppet is a really,really vast topic. This article is really basic and it doesn't goes more than just even toe's deep into the possibilities and capabilities of Puppet. It doesn't try to explain Puppet ... just how you get it up and running and do basic tests. There are many good books on Puppet. Please read one of them, and the concepts and the example will get much clearer immediately. (more)

At the Java DEMOgrounds - ZeroTurnaround and its LiveRebel 2.5

- by Janice J. Heiss

At the ZeroTurnaround demo, I spoke with Krishnan Badrinarayanan, their Product Marketing Manager. ZeroTurnaround, the creator of JRebel and LiveRebel, describes itself on their site as a company “dedicated to changing the way the world develops, tests and runs Java applications."“We just launched LiveRebel 2.5 today,” stated Badrinarayanan, “which enables companies to embrace the concept and practice of continuous delivery, which means having a pipeline that takes products right from the developers to an end-user, faster, more frequently -- all the while ensuring that it’s a quality product that does not break in production. So customers don’t feel the discontinuity that something has changed under them and that they can’t deal with the change. And all this happens while there is zero down time.”He pointed out that Salesforce.com is not useable from 3 a.m. to 5 a.m. on Saturday because they are engaged in maintenance. “With LiveRebel 2.5, you can unify the whole delivery chain without having any downtime at all,” he said. “There are many products that tell customers to take their tools and change how they work as an organization so that you they have to conform to the way the tool prescribes them to work as an application team. We take a more pragmatic approach. A lot of companies might use Jenkins or Bamboo to do continuous integration. We extend that. We say, take our product, take LiveRebel okay, and integrate it with Jenkins – you can do that quickly, so that, in half a day, you will be up and running. And let LiveRebel automate your deployment processes and all the automated tasks that go with it. Right from tests to the staging environment to production -- all with zero downtime and with no impact on users currently using the system.” “So if you were to make the update right now and you had 100 users on your system, they would not even know this was happening. It would maintain their sessions and transfer them over to the new version, all in the background.”

Update 3 for "NetBeans Platform for Beginners"

- by Geertjan

The latest monthly update of NetBeans Platform for Beginners was released during the last few days. Without any question at all, this book is awesome. I love how it is a 'living book' and that on a monthly basis new updates are made available. In this particular update, as before, reader comments and questions have led to changes and enhancements in the book. In addition, there's now a tighter integration between the long list of samples on GitHub and the book, since wherever a sample relates to a text in the book, the book has a handy icon, so that you know when to hop over to GitHub to get a related sample. Do you have comments or questions about the book? That's what the feedback link is for: https://leanpub.com/nbp4beginners/feedback And there's also a free sample, just in case you'd like to get a feel for the book prior to buying it: http://samples.leanpub.com/nbp4beginners-sample.pdf If you're from a company where you're all sharing a single copy of the book, it would be great if you'd go back and support this great project (and hopefully encourage future books being written) by buying additional copies, ideally one for each developer. Let's show the authors that writing books on the NetBeans Platform is a really profitable thing to do (and I'm hoping they'll write one on Maven and the NetBeans Platform, as well)!

"Exception has been thrown by the target of an invocation" Running Tests - VS2008 SP1

- by omatrot

I'm using Visual Studio 2008 Team Suite and I'm unable to run tests and display the Test/Windows/Test Result Window. The result is a dialog box with the following content : "Exception has been thrown by the target of an invocation". Team Explorer has been installed after Visual Studio 2008 SP1. So I have re-apllied the service pack. Searching the web I found that this error is pretty common but unfortunately, the proposed solutions does not work for me. The problem was never analysed so I decided to give it a try : I reproduced the problem on a computer, attached the process with windbg and start with the basic investigations.

At the Java DEMOgrounds - JavaFX

- by Janice J. Heiss

JavaFX has made rapid progress in the last year, as is evidenced by the wealth of demos on display. A few questions appear to be prominent in the minds of JavaFX enthusiasts. Here are some questions with answers provided by Oracle’s JavaFX team.When will the rest of the JavaFX code be available in open source?Oracle has started to open source JavaFX. The existing platform code will finish being committed to OpenJFX by the end of the year.Why should I use JavaFX instead of HTML5?We see JavaFX as complementary to HTML5, and most companies we talk to react positively once they understand how they can benefit from a hybrid solution. As most HTML5 developers will tell you, the biggest obstacle to deploying HTML5 applications is fragmentation. JavaFX offers a convenient way to render HTML and JavaScript within its WebView component, which provides the same level of quality and features across Windows, Mac, and Linux. Additionally, JavaScript in WebView can make calls into the Java code, and vice versa, allowing developers to tap into the best of both worlds.What is the market penetration of JavaFX? It is currently limited, as we've just made available JavaFX on Mac and Linux in August, but we expect JavaFX to be present on millions of desktop-type systems now that JavaFX is included as part of the JRE. We have also significantly lowered the level of effort required to deploy an application bundling the JRE and JavaFX runtime libraries. Finally, we are seeing a lot of interest by companies operating in the embedded market, who have found it hard to develop compelling UIs with existing technologies.Below are summaries of JavaFX Demos on display at JavaOne 2012:JavaFX EnsembleEnsemble is a collection of over 100 JavaFX samples packaged as a JavaFX application. This demo is especially useful to those new to JavaFX, or those not familiar with its latest features (e.g. canvas, color picker). Ensemble is the reference for getting familiar with JavaFX functionality. Each sample can be run from within Ensemble, and the API for each sample, as well as the source code are available alongside the sample.The samples source code can be saved as a NetBeans project for convenience purposes, or can be copied as is in any other Java IDE. The version of Ensemble shown is packaged as a native Windows application, including the JRE and JavaFX libraries. It was created with the JavaFX packager, which provides multiple packaging options, and frees developers from the cumbersome and error-prone process of packaging a Java application.FX Experience ToolsFX Experience Tools is a JavaFX application that provides different utilities to create new skins for your JavaFX applications. One of the most powerful features of JavaFX is the ability to skin applications via CSS. Since not all Java developers are familiar with CSS, these utilities are a great starting point to create custom skins. JavaFX allows developers to easily customize the look and feel of their applications through CSS. FX Experience Tools makes it easy to create new themes for JavaFX applications, even if you are not familiar with CSS. FX Experience Tools is a JavaFX application packaged as a native application including the JRE and JavaFX runtime libraries. FX Experience tools shows how this type of deployment simplifies the packaging of Java applications without requiring developers to master the intricacies of Java application packaging. The download site for FX Experience Tools is http://fxexperience.com/2012/03/announcing-fx-experience-tools/ JavaFX Scene BuilderJavaFX Scene Builder is a visual layout tool that lets users quickly design the UI of your JavaFX application, without coding. Users can drag and drop UI components, modify their properties, apply style sheets, and the FXML code they create for the layout is automatically generated in the background. The result is an FXML file that can then be combined with a Java project by binding the UI to the application’s logic. Developers can easily create user interfaces for their application, as well as separate the application’s UI from the application logic for easier maintenance. Attendees can get this app by going to javafx.com and checking the link at top of the “Overview” page.Scene Builder allows developers to easily layout JavaFX UI controls, charts, shapes, and containers, so that you can quickly prototype user interfaces. It generates FXML, an XML-based markup language that enables users to define an application’s user interface, separately from the application logic. Scene Builder can be used in combination with any Java IDE, but is more tightly integrated with NetBeans IDE.

What's up with LDoms: Part 4 - Virtual Networking Explained

- by Stefan Hinker

I'm back from my summer break (and some pressing business that kept me away from this), ready to continue with Oracle VM Server for SPARC ;-) In this article, we'll have a closer look at virtual networking. Basic connectivity as we've seen it in the first, simple example, is easy enough. But there are numerous options for the virtual switches and virtual network ports, which we will discuss in more detail now. In this section, we will concentrate on virtual networking - the capabilities of virtual switches and virtual network ports - only. Other options involving hardware assignment or redundancy will be covered in separate sections later on. There are two basic components involved in virtual networking for LDoms: Virtual switches and virtual network devices. The virtual switch should be seen just like a real ethernet switch. It "runs" in the service domain and moves ethernet packets back and forth. A virtual network device is plumbed in the guest domain. It corresponds to a physical network device in the real world. There, you'd be plugging a cable into the network port, and plug the other end of that cable into a switch. In the virtual world, you do the same: You create a virtual network device for your guest and connect it to a virtual switch in a service domain. The result works just like in the physical world, the network device sends and receives ethernet packets, and the switch does all those things ethernet switches tend to do. If you look at the reference manual of Oracle VM Server for SPARC, there are numerous options for virtual switches and network devices. Don't be confused, it's rather straight forward, really. Let's start with the simple case, and work our way to some more sophisticated options later on. In many cases, you'll want to have several guests that communicate with the outside world on the same ethernet segment. In the real world, you'd connect each of these systems to the same ethernet switch. So, let's do the same thing in the virtual world: root@sun # ldm add-vsw net-dev=nxge2 admin-vsw primary root@sun # ldm add-vnet admin-net admin-vsw mars root@sun # ldm add-vnet admin-net admin-vsw venus We've just created a virtual switch called "admin-vsw" and connected it to the physical device nxge2. In the physical world, we'd have powered up our ethernet switch and installed a cable between it and our big enterprise datacenter switch. We then created a virtual network interface for each one of the two guest systems "mars" and "venus" and connected both to that virtual switch. They can now communicate with each other and with any system reachable via nxge2. If primary were running Solaris 10, communication with the guests would not be possible. This is different with Solaris 11, please see the Admin Guide for details. Note that I've given both the vswitch and the vnet devices some sensible names, something I always recommend. Unless told otherwise, the LDoms Manager software will automatically assign MAC addresses to all network elements that need one. It will also make sure that these MAC addresses are unique and reuse MAC addresses to play nice with all those friendly DHCP servers out there. However, if we want to do this manually, we can also do that. (One reason might be firewall rules that work on MAC addresses.) So let's give mars a manually assigned MAC address: root@sun # ldm set-vnet mac-addr=0:14:4f:f9:c4:13 admin-net mars Within the guest, these virtual network devices have their own device driver. In Solaris 10, they'd appear as "vnet0". Solaris 11 would apply it's usual vanity naming scheme. We can configure these interfaces just like any normal interface, give it an IP-address and configure sophisticated routing rules, just like on bare metal. In many cases, using Jumbo Frames helps increase throughput performance. By default, these interfaces will run with the standard ethernet MTU of 1500 bytes. To change this, it is usually sufficient to set the desired MTU for the virtual switch. This will automatically set the same MTU for all vnet devices attached to that switch. Let's change the MTU size of our admin-vsw from the example above: root@sun # ldm set-vsw mtu=9000 admin-vsw primary Note that that you can set the MTU to any value between 1500 and 16000. Of course, whatever you set needs to be supported by the physical network, too. Another very common area of network configuration is VLAN tagging. This can be a little confusing - my advise here is to be very clear on what you want, and perhaps draw a little diagram the first few times. As always, keeping a configuration simple will help avoid errors of all kind. Nevertheless, VLAN tagging is very usefull to consolidate different networks onto one physical cable. And as such, this concept needs to be carried over into the virtual world. Enough of the introduction, here's a little diagram to help in explaining how VLANs work in LDoms: Let's remember that any VLANs not explicitly tagged have the default VLAN ID of 1. In this example, we have a vswitch connected to a physical network that carries untagged traffic (VLAN ID 1) as well as VLANs 11, 22, 33 and 44. There might also be other VLANs on the wire, but the vswitch will ignore all those packets. We also have two vnet devices, one for mars and one for venus. Venus will see traffic from VLANs 33 and 44 only. For VLAN 44, venus will need to configure a tagged interface "vnet44000". For VLAN 33, the vswitch will untag all incoming traffic for venus, so that venus will see this as "normal" or untagged ethernet traffic. This is very useful to simplify guest configuration and also allows venus to perform Jumpstart or AI installations over this network even if the Jumpstart or AI server is connected via VLAN 33. Mars, on the other hand, has full access to untagged traffic from the outside world, and also to VLANs 11,22 and 33, but not 44. On the command line, we'd do this like this: root@sun # ldm add-vsw net-dev=nxge2 pvid=1 vid=11,22,33,44 admin-vsw primary root@sun # ldm add-vnet admin-net pvid=1 vid=11,22,33 admin-vsw mars root@sun # ldm add-vnet admin-net pvid=33 vid=44 admin-vsw venus Finally, I'd like to point to a neat little option that will make your live easier in all those cases where configurations tend to change over the live of a guest system. It's the "id=<somenumber>" option available for both vswitches and vnet devices. Normally, Solaris in the guest would enumerate network devices sequentially. However, it has ways of remembering this initial numbering. This is good in the physical world. In the virtual world, whenever you unbind (aka power off and disassemble) a guest system, remove and/or add network devices and bind the system again, chances are this numbering will change. Configuration confusion will follow suit. To avoid this, nail down the initial numbering by assigning each vnet device it's device-id explicitly: root@sun # ldm add-vnet admin-net id=1 admin-vsw venus Please consult the Admin Guide for details on this, and how to decipher these network ids from Solaris running in the guest. Thanks for reading this far. Links for further reading are essentially only the Admin Guide and Reference Manual and can be found above. I hope this is useful and, as always, I welcome any comments.

Complex type support in process flow – XMLTYPE

- by shawn

Before OWB 11.2 release, there are only 5 simple data types supported in process flow: DATE, BOOLEAN, INTEGER, FLOAT and STRING. A new complex data type – XMLTYPE is added in 11.2, in order to support complex data being passed between the process flow activities. In this article we will give a simple example to illustrate the usage of the new type and some related editors. Suppose there is a bookstore that uses XML format orders as shown below (we use the simplest form for the illustration purpose), then we can create a process flow to handle the order, take the order as the input, then extract necessary information, and generate a confirmation email to the customer automatically. <order id=’0001’> <customer> <name>Tom</name> <email>[email protected]</email> </customer> <book id=’Java_001’> <quantity>3</quantity> </book> </order> Considering a simple user case here: we use an input parameter/variable with XMLTYPE to hold the XML content of the order; then we can use an Assign activity to retrieve the email info from the order; after that, we can create an email activity to send the email (Other activities might be added in practical case, but will not be described here). 1) Set XML content value For testing purpose, we will create a variable to hold the sample order, and then this will be used among the process flow activities. When the variable is of XMLTYPE and the “Literal” value is set the true, the advance editor will be enabled. Click the “Advance Editor” shown as above, a simple xml editor will popup. The editor has basic features like syntax highlight and check as shown below: We can also do the basic validation or validation against schema with the editor by selecting the normalized schema. With this, it will be easier to provide the value for XMLTYPE variables. 2) Extract information from XML content After setting the value, we need to extract the email information with the Assign activity. In process flow, an enhanced expression builder is used to help users construct the XPath for extracting values from XML content. When the variable’s literal value is set the false, the advance editor is enabled. Click the button, the advance editor will popup, as shown below: The editor is based on the expression builder (which is often used in mapping etc), an XPath lib panel is appended which provides some help information on how to write the XPath. The expression used here is: “XMLTYPE.EXTRACT(XML_ORDER,'/order/customer/email/text()').getStringVal()”, which uses ‘/order/customer/email/text()’ as the XPath to extract the email info from the XML document. A variable called “EMAIL_ADDR” is created with String data type to hold the value extracted. Then we bind the “VARIABLE” parameter of Assign activity to “EMAIL_ADDR” variable, which means the value of the “EMAIL_ADDR” activity will be set to the result of the “VALUE” parameter of Assign activity. 3) Use the extracted information in Email activity We bind the “TO_ADDRESS” parameter of the email activity to the “EMAIL_ADDR” variable created in above step. We can also extract other information from the xml order directly through the expression, for example, we can set the “MESSAGE_BODY” with value “'Dear '||XMLTYPE.EXTRACT(XML_ORDER,'/order/customer/name/text()').getStringVal()||chr(13)||chr(10)||' You have ordered '||XMLTYPE.EXTRACT(XML_ORDER,'/order/book/quantity/text()').getStringVal()||' '||XMLTYPE.EXTRACT(XML_ORDER,'/order/book/@id').getStringVal()”. This expression will extract the customer name, the quantity and the book id from the order to compose the message body. To make the email activity work, we need provide some other necessary information, Such as “SMTP_SERVER” (which is the SMTP server used to send the emails, like “mail.bookstore.com”. The default PORT number is set to 25. You need to change the value accordingly), “FROM_ADDRESS” and “SUBJECT”. Then the process flow is ready to go. After deploying the process flow package, we can simply run the process flow to check if the result is as expected (An email will be sent to the specified email address with proper subject and message body). Note: In oracle 11g, there is an enhanced security feature - ACL (Access Control List), which restrict the network access within db, so we need to edit the list to allow UTL_SMTP work if you are using oracle 11g. Refer to chapter “Access Control Lists for UTL_TCP/HTTP/SMTP” and “Managing Fine-Grained Access to External Network Services” for more details. In previous releases, XMLTYPE already exists in other OWB objects, like mapping/transformation etc. When the mapping/transformation is dragged into a process flow, the parameters with XMLTYPE are mapped to STRING. Now with the XMLTYPE support in process flow, the XMLTYPE will map to XMLTYPE in a more natural way, and we can leverage the new data type for the design.

DTracing a PHPUnit Test: Looking at Functional Programming

- by cj

Here's a quick example of using DTrace Dynamic Tracing to work out what a PHP code base does. I was reading the article Functional Programming in PHP by Patkos Csaba and wondering how efficient this stype of programming is. I thought this would be a good time to fire up DTrace and see what is going on. Since DTrace is "always available" even in production machines (once PHP is compiled with --enable-dtrace), this was easy to do. I have Oracle Linux with the UEK3 kernel and PHP 5.5 with DTrace static probes enabled, as described in DTrace PHP Using Oracle Linux 'playground' Pre-Built Packages I installed the Functional Programming sample code and Sebastian Bergmann's PHPUnit. Although PHPUnit is included in the Functional Programming example, I found it easier to separately download and use its phar file: cd ~/Desktop wget -O master.zip https://github.com/tutsplus/functional-programming-in-php/archive/master.zip wget https://phar.phpunit.de/phpunit.phar unzip master.zip I created a DTrace D script functree.d: #pragma D option quiet self int indent; BEGIN { topfunc = $1; } php$target:::function-entry /copyinstr(arg0) == topfunc/ { self->follow = 1; } php$target:::function-entry /self->follow/ { self->indent += 2; printf("%*s %s%s%s\n", self->indent, "->", arg3?copyinstr(arg3):"", arg4?copyinstr(arg4):"", copyinstr(arg0)); } php$target:::function-return /self->follow/ { printf("%*s %s%s%s\n", self->indent, "<-", arg3?copyinstr(arg3):"", arg4?copyinstr(arg4):"", copyinstr(arg0)); self->indent -= 2; } php$target:::function-return /copyinstr(arg0) == topfunc/ { self->follow = 0; } This prints a PHP script function call tree starting from a given PHP function name. This name is passed as a parameter to DTrace, and assigned to the variable topfunc when the DTrace script starts. With this D script, choose a PHP function that isn't recursive, or modify the script to set self->follow = 0 only when all calls to that function have unwound. From looking at the sample FunSets.php code and its PHPUnit test driver FunSetsTest.php, I settled on one test function to trace: function testUnionContainsAllElements() { ... } I invoked DTrace to trace function calls invoked by this test with # dtrace -s ./functree.d -c 'php phpunit.phar \ /home/cjones/Desktop/functional-programming-in-php-master/FunSets/Tests/FunSetsTest.php' \ '"testUnionContainsAllElements"' The core of this command is a call to PHP to run PHPUnit on the FunSetsTest.php script. Outside that, DTrace is called and the PID of PHP is passed to the D script $target variable so the probes fire just for this invocation of PHP. Note the quoting around the PHP function name passed to DTrace. The parameter must have double quotes included so DTrace knows it is a string. The output is: PHPUnit 3.7.28 by Sebastian Bergmann. ......-> FunSetsTest::testUnionContainsAllElements -> FunSets::singletonSet <- FunSets::singletonSet -> FunSets::singletonSet <- FunSets::singletonSet -> FunSets::union <- FunSets::union -> FunSets::contains -> FunSets::{closure} -> FunSets::contains -> FunSets::{closure} <- FunSets::{closure} <- FunSets::contains <- FunSets::{closure} <- FunSets::contains -> PHPUnit_Framework_Assert::assertTrue -> PHPUnit_Framework_Assert::isTrue <- PHPUnit_Framework_Assert::isTrue -> PHPUnit_Framework_Assert::assertThat -> PHPUnit_Framework_Constraint::count <- PHPUnit_Framework_Constraint::count -> PHPUnit_Framework_Constraint::evaluate -> PHPUnit_Framework_Constraint_IsTrue::matches <- PHPUnit_Framework_Constraint_IsTrue::matches <- PHPUnit_Framework_Constraint::evaluate <- PHPUnit_Framework_Assert::assertThat <- PHPUnit_Framework_Assert::assertTrue -> FunSets::contains -> FunSets::{closure} -> FunSets::contains -> FunSets::{closure} <- FunSets::{closure} <- FunSets::contains -> FunSets::contains -> FunSets::{closure} <- FunSets::{closure} <- FunSets::contains <- FunSets::{closure} <- FunSets::contains -> PHPUnit_Framework_Assert::assertTrue -> PHPUnit_Framework_Assert::isTrue <- PHPUnit_Framework_Assert::isTrue -> PHPUnit_Framework_Assert::assertThat -> PHPUnit_Framework_Constraint::count <- PHPUnit_Framework_Constraint::count -> PHPUnit_Framework_Constraint::evaluate -> PHPUnit_Framework_Constraint_IsTrue::matches <- PHPUnit_Framework_Constraint_IsTrue::matches <- PHPUnit_Framework_Constraint::evaluate <- PHPUnit_Framework_Assert::assertThat <- PHPUnit_Framework_Assert::assertTrue -> FunSets::contains -> FunSets::{closure} -> FunSets::contains -> FunSets::{closure} <- FunSets::{closure} <- FunSets::contains -> FunSets::contains -> FunSets::{closure} <- FunSets::{closure} <- FunSets::contains <- FunSets::{closure} <- FunSets::contains -> PHPUnit_Framework_Assert::assertFalse -> PHPUnit_Framework_Assert::isFalse -> {closure} -> main <- main <- {closure} <- PHPUnit_Framework_Assert::isFalse -> PHPUnit_Framework_Assert::assertThat -> PHPUnit_Framework_Constraint::count <- PHPUnit_Framework_Constraint::count -> PHPUnit_Framework_Constraint::evaluate -> PHPUnit_Framework_Constraint_IsFalse::matches <- PHPUnit_Framework_Constraint_IsFalse::matches <- PHPUnit_Framework_Constraint::evaluate <- PHPUnit_Framework_Assert::assertThat <- PHPUnit_Framework_Assert::assertFalse <- FunSetsTest::testUnionContainsAllElements ... Time: 1.85 seconds, Memory: 3.75Mb OK (9 tests, 23 assertions) The periods correspond to the successful tests before and after (and from) the test I was tracing. You can see the function entry ("->") and return ("<-") points. Cross checking with the testUnionContainsAllElements() source code confirms the two singletonSet() calls, one union() call, two assertTrue() calls and finally an assertFalse() call. These assertions have a contains() call as a parameter, so contains() is called before the PHPUnit assertion functions are run. You can see contains() being called recursively, and how the closures are invoked. If you want to focus on the application logic and suppress the PHPUnit function trace, you could turn off tracing when assertions are being checked by adding D clauses checking the entry and exit of assertFalse() and assertTrue(). But if you want to see all of PHPUnit's code flow, you can modify the functree.d code that sets and unsets self-follow, and instead change it to toggle the variable in request-startup and request-shutdown probes: php$target:::request-startup { self->follow = 1 } php$target:::request-shutdown { self->follow = 0 } Be prepared for a large amount of output!

Benchmarking MySQL Replication with Multi-Threaded Slaves

As the results demonstrate, Multi-Threaded Slaves delivers 5x higher replication performance based on a configuration with 10 databases/schemas. For real-world deployments, higher replication performance directly translates to: · Improved consistency of reads from slaves (i.e. reduced risk of reading "stale" data) · Reduced risk of data loss should the master fail before replicating all events in its binary log (binlog) The multi-threaded slave splits processing between worker threads based on schema, allowing updates to be applied in parallel, rather than sequentially. This delivers benefits to those workloads that isolate application data using databases - e.g. multi-tenant systems deployed in cloud environments. Multi-Threaded Slaves are just one of many enhancements to replication previewed as part of the MySQL 5.6 Development Release, which include: · Global Transaction Identifiers coupled with MySQL utilities for automatic failover / switchover and slave promotion · Crash Safe Slaves and Binlog · Optimized Row Based Replication · Replication Event Checksums · Time Delayed Replication These and many more are discussed in the “MySQL 5.6 Replication: Enabling the Next Generation of Web & Cloud Services” Developer Zone article Back to the benchmark - details are as follows. Environment The test environment consisted of two Linux servers: · one running the replication master · one running the replication slave. Only the slave was involved in the actual measurements, and was based on the following configuration: - Hardware: Oracle Sun Fire X4170 M2 Server - CPU: 2 sockets, 6 cores with hyper-threading, 2930 MHz. - OS: 64-bit Oracle Enterprise Linux 6.1 - Memory: 48 GB Test Procedure Initial Setup: Two MySQL servers were started on two different hosts, configured as replication master and slave. 10 sysbench schemas were created, each with a single table: CREATE TABLE `sbtest` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `k` int(10) unsigned NOT NULL DEFAULT '0', `c` char(120) NOT NULL DEFAULT '', `pad` char(60) NOT NULL DEFAULT '', PRIMARY KEY (`id`), KEY `k` (`k`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 10,000 rows were inserted in each of the 10 tables, for a total of 100,000 rows. When the inserts had replicated to the slave, the slave threads were stopped. The slave data directory was copied to a backup location and the slave threads position in the master binlog noted. 10 sysbench clients, each configured with 10 threads, were spawned at the same time to generate a random schema load against each of the 10 schemas on the master. Each sysbench client executed 10,000 "update key" statements: UPDATE sbtest set k=k+1 WHERE id = <random row> In total, this generated 100,000 update statements to later replicate during the test itself. Test Methodology: The number of slave workers to test with was configured using: SET GLOBAL slave_parallel_workers=<workers> Then the slave IO thread was started and the test waited for all the update queries to be copied over to the relay log on the slave. The benchmark clock was started and then the slave SQL thread was started. The test waited for the slave SQL thread to finish executing the 100k update queries, doing "select master_pos_wait()". When master_pos_wait() returned, the benchmark clock was stopped and the duration calculated. The calculated duration from the benchmark clock should be close to the time it took for the SQL thread to execute the 100,000 update queries. The 100k queries divided by this duration gave the benchmark metric, reported as Queries Per Second (QPS). Test Reset: The test-reset cycle was implemented as follows: · the slave was stopped · the slave data directory replaced with the previous backup · the slave restarted with the slave threads replication pointer repositioned to the point before the update queries in the binlog. The test could then be repeated with identical set of queries but a different number of slave worker threads, enabling a fair comparison. The Test-Reset cycle was repeated 3 times for 0-24 number of workers and the QPS metric calculated and averaged for each worker count. MySQL Configuration The relevant configuration settings used for MySQL are as follows: binlog-format=STATEMENT relay-log-info-repository=TABLE master-info-repository=TABLE As described in the test procedure, the slave_parallel_workers setting was modified as part of the test logic. The consequence of changing this setting is: 0 worker threads: - current (i.e. single threaded) sequential mode - 1 x IO thread and 1 x SQL thread - SQL thread both reads and executes the events 1 worker thread: - sequential mode - 1 x IO thread, 1 x Coordinator SQL thread and 1 x Worker thread - coordinator reads the event and hands it to the worker who executes 2+ worker threads: - parallel execution - 1 x IO thread, 1 x Coordinator SQL thread and 2+ Worker threads - coordinator reads events and hands them to the workers who execute them Results Figure 1 below shows that Multi-Threaded Slaves deliver ~5x higher replication performance when configured with 10 worker threads, with the load evenly distributed across our 10 x schemas. This result is compared to the current replication implementation which is based on a single SQL thread only (i.e. zero worker threads). Figure 1: 5x Higher Performance with Multi-Threaded Slaves The following figure shows more detailed results, with QPS sampled and reported as the worker threads are incremented. The raw numbers behind this graph are reported in the Appendix section of this post. Figure 2: Detailed Results As the results above show, the configuration does not scale noticably from 5 to 9 worker threads. When configured with 10 worker threads however, scalability increases significantly. The conclusion therefore is that it is desirable to configure the same number of worker threads as schemas. Other conclusions from the results: · Running with 1 worker compared to zero workers just introduces overhead without the benefit of parallel execution. · As expected, having more workers than schemas adds no visible benefit. Aside from what is shown in the results above, testing also demonstrated that the following settings had a very positive effect on slave performance: relay-log-info-repository=TABLE master-info-repository=TABLE For 5+ workers, it was up to 2.3 times as fast to run with TABLE compared to FILE. Conclusion As the results demonstrate, Multi-Threaded Slaves deliver significant performance increases to MySQL replication when handling multiple schemas. This, and the other replication enhancements introduced in MySQL 5.6 are fully available for you to download and evaluate now from the MySQL Developer site (select Development Release tab). You can learn more about MySQL 5.6 from the documentation Please don’t hesitate to comment on this or other replication blogs with feedback and questions. Appendix – Detailed Results

How to ensure custom serverListener events fires before action events

If the custom event however is queued from an af:clientListener on a command component, then the command component's action and action listener methods fire before the queued custom event. If you have a use case, for example in combination with client side integration of 3rd party technologies like HTML, Applets or similar, then you want to change the order of execution. The way to change the execution order is to invoke the command item action from the client event method that handles the custom event propagated by the af:serverListener tag. The following four steps ensure your successful doing this 1. Call cancel() on the event object passed to the client JavaScript function invoked by the af:clientListener tag 2. Call the custom event as an immediate action by setting the last argument in the custom event call to true function invokeCustomEvent(evt){ evt.cancel(); var custEvent = new AdfCustomEvent( evt.getSource(), "mycustomevent", {message:"Hello World"}, true); custEvent.queue(); } 3. When handling the custom event on the server, lookup the command item, for example a button, to queue its action event. This way you simulate a user clicking the button. Use the following code ActionEvent event = new ActionEvent(component); event.setPhaseId(PhaseId.INVOKE_APPLICATION); event.queue(); The component reference needs to be changed with the handle to the command item which action method you want to execute. 4. If the command component has behavior tags, like af:fileDownloadActionListener, or af:setPropertyListener, defined, then these are also executed when the action event is queued. However, behavior tags, like the file download action listener, may require a full page refresh to be issued to work, in which case the custom event cannot be issued as a partial refresh. File download action tag: http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e12419/tagdoc/af_fileDownloadActionListener.html " Since file downloads must be processed with an ordinary request - not XMLHttp AJAX requests - this tag forces partialSubmit to be false on the parent component, if it supports that attribute." To issue a custom event as a non-partial submit, the previously shown sample code would need to be changed as shown below function invokeCustomEvent(evt){ evt.cancel(); var custEvent = new AdfCustomEvent( evt.getSource(), "mycustomevent", {message:"Hello World"}, true); custEvent.queue(false); } To learn more about custom events and the af:serverListener, please refer to the tag documentation: http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e12419/tagdoc/af_serverListener.html

Delivering the Integrated Portal Experience!

- by Michael Snow

v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Guest post by Richard Maldonado, Principal Product Manager, Oracle WebCenter Portal Organizations are still struggling to standardize on a user interaction platform which can meet the needs of all their target audiences. This has not only resulted in inefficient and inconsistent experiences for their users, but it also creates inefficiencies (productivity and costs) for the departments that manage the applications and information systems. Portals have historically been the unifying platform that provide IT with a common interface which can securely surface the most relevant interactions for a given user and/or group of users. However, organizations have found that the technologies available have either not provided the flexibility necessary to address all of their use cases, or they rely too much on IT resources to manage, maintain, and evolve. Empowering the Business Groups The core issue that IT departments face with delivering portal experiences is having enough resources to respond and address the influx of requirements which come in from the business. Commonly, when a business group wants a new portal site established for their group, they will submit a request to the IT dept, the IT dept then assigns a resource to an administrator and/or developer to build. Unfortunately, this approach is not scalable, it can be a time consuming activity which requires significant interaction between the business owner and the IT resource. A modern user interaction platforms should empower the business groups by providing them tools which they can use to build and manage the portal experiences without the need for IT's involvement. And because business groups rarely have technical resources (developers) on staff, the tools must be easy enough that virtually any business user could use. In addition, the tool must be powerful enough to allow them to build the experience that they need, things such as creating a whole new portal, add/manage page and page hierarchy, manage user/group access, add/modify components within the page, etc. This balance between ease-of-use and flexibility is key to the successful adoption of tools which will ultimately reduce the burden on IT, respond to the needs of the business, and deliver high-value experiences for the users. Ready or Not, Here They Come: Smartphones and Tablets Recently, several studies have highlighted that smartphone and tablet-style devices have overtaken PC's in both sales and usage. This shift is further driving organizations to revaluate how they're delivering data, information, and applications to their users. Users are expecting to get the same level of access and interaction, but in a ways which are optimized for the capabilities of the device that they are using. Expect More With the ever growing number of new IT projects and flat/shrinking budgets, organizations are looking for comprehensive solutions which can deliver integrated web experiences that are tailored for the users and optimized for mobile devices. Piecing together a number of point solutions is no longer an option. A modern portal technology should not only address the traditional needs of integrating and surfacing back-end applications/information, but it should enable the business through easy-to-use tools and accelerate the delivery of mobile optimized experiences. v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} 12.00 Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";} 12.00 Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-family:"Calibri","sans-serif"; mso-ascii- mso-ascii-theme-font:minor-latin; mso-hansi- mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} WebCenter in Action Series: Qualcomm Provides a Seamless Experience for Customers with Oracle WebCenter Featuring Qualcomm & Keste 12.00 Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 -"/ /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} 12.00 Normal 0 false false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-family:"Calibri","sans-serif"; mso-fareast- mso-bidi-font-family:"Times New Roman";}

Building an OpenStack Cloud for Solaris Engineering, Part 1

- by Dave Miner

One of the signature features of the recently-released Solaris 11.2 is the OpenStack cloud computing platform. Over on the Solaris OpenStack blog the development team is publishing lots of details about our version of OpenStack Havana as well as some tips on specific features, and I highly recommend reading those to get a feel for how we've leveraged Solaris's features to build a top-notch cloud platform. In this and some subsequent posts I'm going to look at it from a different perspective, which is that of the enterprise administrator deploying an OpenStack cloud. But this won't be just a theoretical perspective: I've spent the past several months putting together a deployment of OpenStack for use by the Solaris engineering organization, and now that it's in production we'll share how we built it and what we've learned so far.In the Solaris engineering organization we've long had dedicated lab systems dispersed among our various sites and a home-grown reservation tool for developers to reserve those systems; various teams also have private systems for specific testing purposes. But as a developer, it can still be difficult to find systems you need, especially since most Solaris changes require testing on both SPARC and x86 systems before they can be integrated. We've added virtual resources over the years as well in the form of LDOMs and zones (both traditional non-global zones and the new kernel zones). Fundamentally, though, these were all still deployed in the same model: our overworked lab administrators set up pre-configured resources and we then reserve them. Sounds like pretty much every traditional IT shop, right? Which means that there's a lot of opportunity for efficiencies from greater use of virtualization and the self-service style of cloud computing. As we were well into development of OpenStack on Solaris, I was recruited to figure out how we could deploy it to both provide more (and more efficient) development and test resources for the organization as well as a test environment for Solaris OpenStack.At this point, let's acknowledge one fact: deploying OpenStack is hard. It's a very complex piece of software that makes use of sophisticated networking features and runs as a ton of service daemons with myriad configuration files. The web UI, Horizon, doesn't often do a good job of providing detailed errors. Even the command-line clients are not as transparent as you'd like, though at least you can turn on verbose and debug messaging and often get some clues as to what to look for, though it helps if you're good at reading JSON structure dumps. I'd already learned all of this in doing a single-system Grizzly-on-Linux deployment for the development team to reference when they were getting started so I at least came to this job with some appreciation for what I was taking on. The good news is that both we and the community have done a lot to make deployment much easier in the last year; probably the easiest approach is to download the OpenStack Unified Archive from OTN to get your hands on a single-system demonstration environment. I highly recommend getting started with something like it to get some understanding of OpenStack before you embark on a more complex deployment. For some situations, it may in fact be all you ever need. If so, you don't need to read the rest of this series of posts!In the Solaris engineering case, we need a lot more horsepower than a single-system cloud can provide. We need to support both SPARC and x86 VM's, and we have hundreds of developers so we want to be able to scale to support thousands of VM's, though we're going to build to that scale over time, not immediately. We also want to be able to test both Solaris 11 updates and a release such as Solaris 12 that's under development so that we can work out any upgrade issues before release. One thing we don't have is a requirement for extremely high availability, at least at this point. We surely don't want a lot of down time, but we can tolerate scheduled outages and brief (as in an hour or so) unscheduled ones. Thus I didn't need to spend effort on trying to get high availability everywhere.The diagram below shows our initial deployment design. We're using six systems, most of which are x86 because we had more of those immediately available. All of those systems reside on a management VLAN and are connected with a two-way link aggregation of 1 Gb links (we don't yet have 10 Gb switching infrastructure in place, but we'll get there). A separate VLAN provides "public" (as in connected to the rest of Oracle's internal network) addresses, while we use VxLANs for the tenant networks. One system is more or less the control node, providing the MySQL database, RabbitMQ, Keystone, and the Nova API and scheduler as well as the Horizon console. We're curious how this will perform and I anticipate eventually splitting at least the database off to another node to help simplify upgrades, but at our present scale this works.I had a couple of systems with lots of disk space, one of which was already configured as the Automated Installation server for the lab, so it's just providing the Glance image repository for OpenStack. The other node with lots of disks provides Cinder block storage service; we also have a ZFS Storage Appliance that will help back-end Cinder in the near future, I just haven't had time to get it configured in yet.There's a separate system for Neutron, which is our Elastic Virtual Switch controller and handles the routing and NAT for the guests. We don't have any need for firewalling in this deployment so we're not doing so. We presently have only two tenants defined, one for the Solaris organization that's funding this cloud, and a separate tenant for other Oracle organizations that would like to try out OpenStack on Solaris. Each tenant has one VxLAN defined initially, but we can of course add more. Right now we have just a single /24 network for the floating IP's, once we get demand up to where we need more then we'll add them.Finally, we have started with just two compute nodes; one is an x86 system, the other is an LDOM on a SPARC T5-2. We'll be adding more when demand reaches the level where we need them, but as we're still ramping up the user base it's less work to manage fewer nodes until then.My next post will delve into the details of building this OpenStack cloud's infrastructure, including how we're using various Solaris features such as Automated Installation, IPS packaging, SMF, and Puppet to deploy and manage the nodes. After that we'll get into the specifics of configuring and running OpenStack itself.

JavaOne Session Report: “50 Tips in 50 Minutes for GlassFish Fans”

- by Janice J. Heiss

At JavaOne 2012 on Monday, Oracle’s Engineer Chris Kasso, and Technology Evangelist Arun Gupta, presented a head-spinning session (CON4701) in which they offered 50 tips for GlassFish fans. Kasso and Gupta alternated back and forth with each presenting 10 tips at a time. An audience of about (appropriately) 50 attentive and appreciative developers was on hand in what has to be one of the most information-packed sessions ever at JavaOne!Aside: I experienced one of the quiet joys of JavaOne when, just before the session began, I spotted Java Champion and JavaOne Rock Star Adam Bien sitting nearby – Adam is someone I have been fortunate to know for many years.GlassFish is a freely available, commercially supported Java EE reference implementation. The session prioritized quantity of tips over depth of information and offered tips that are intended for both seasoned and new users, that are meant to increase the range of functional options available to GlassFish users. The focus was on lesser-known dimensions of GlassFish. Attendees were encouraged to pursue tips that contained new information for them. All 50 tips can be accessed here.Below are several examples of more elaborate tips and a final practical tip on how to get in touch with these folks. Tip #1: Using the login Command * To execute a remote command with asadmin you must provide the admin's user name and password.* The login command allows you to store the login credentials to be reused in subsequent commands.* Can be logged into multiple servers (distinguish by host and port). Example: % asadmin --host ouch login Enter admin user name [default: admin]> Enter admin password> Login information relevant to admin user name [admin] for host [ouch] and admin port [4848] stored at [/Users/ckasso/.asadminpass] successfully. Make sure that this file remains protected. Information stored in this file will be used by asadmin commands to manage the associated domain. Command login executed successfully. % asadmin --host ouch list-clusters c1 not running Command list-clusters executed successfully.Tip #4: Using the AS_DEBUG Env Variable* Environment variable to control client side debug output* Exposes: command processing info URL used to access the command: http://localhost:4848/__asadmin/uptime Raw response from the server Example: % export AS_DEBUG=true % asadmin uptime CLASSPATH= ./../glassfish/modules/admin-cli.jar Commands: [uptime] asadmin extension directory: /work/gf-3.1.2/glassfish3/glassfish/lib/asadm ------- RAW RESPONSE --------- Signature-Version: 1.0 message: Up 7 mins 10 secs milliseconds_value: 430194 keys: milliseconds milliseconds_name: milliseconds use-main-children-attribute: false exit-code: SUCCESS ------- RAW RESPONSE ---------Tip #11: Using Password Aliases * Some resources require a password to access (e.g. DB, JMS, etc.).* The resource connector is defined in the domain.xml.Example:Suppose the DB resource you wish to access requires an entry like this in the domain.xml: <property name="password" value="secretp@ssword"/>But company policies do not allow you to store the password in the clear.* Use password aliases to avoid storing the password in the domain.xml* Create a password alias: % asadmin create-password-alias DB_pw_alias Enter the alias password> Enter the alias password again> Command create-password-alias executed successfully.* The password is stored in domain's encrypted keystore.* Now update the password value in the domain.xml: <property name="password" value="${ALIAS=DB_pw_alias}"/>Tip #21: How to Start GlassFish as a Service * Configuring a server to automatically start at boot can be tedious.* Each platform does it differently.* The create-service command makes this easy. Windows: creates a Windows service Linux: /etc/init.d script Solaris: Service Management Facility (SMF) service * Must execute create-service with admin privileges.* Can be used for the DAS or instances* Try it first with the --dry-run option.* There is a (unsupported) _delete-serverExample: # asadmin create-service domain1 The Service was created successfully. Here are the details: Name of the service:application/GlassFish/domain1 Type of the service:Domain Configuration location of the service:/work/gf-3.1.2.2/glassfish3/glassfish/domains Manifest file location on the system:/var/svc/manifest/application/GlassFish/domain1_work_gf-3.1.2.2_glassfish3_glassfish_domains/Domain-service-smf.xml. You have created the service but you need to start it yourself. Here are the most typical Solaris commands of interest: * /usr/bin/svcs -a | grep domain1 // status * /usr/sbin/svcadm enable domain1 // start * /usr/sbin/svcadm disable domain1 // stop * /usr/sbin/svccfg delete domain1 // uninstallTip #34: Posting a Command via REST* Use wget/curl to execute commands on the DAS.Example: Deploying an application % curl -s -S \ -H 'Accept: application/json' -X POST \ -H 'X-Requested-By: anyvalue' \ -F id=@/path/to/application.war \ -F force=true http://localhost:4848/management/domain/applications/application* Use @ before a file name to tell curl to send the file's contents.* The force option tells GlassFish to force the deployment in case the application is already deployed.* Use wget/curl to execute commands on the DAS.Example: Deploying an application % curl -s -S \ -H 'Accept: application/json' -X POST \ -H 'X-Requested-By: anyvalue' \ -F id=@/path/to/application.war \ -F force=true http://localhost:4848/management/domain/applications/application* Use @ before a file name to tell curl to send the file's contents.* The force option tells GlassFish to force the deployment in case the application is already deployed.Tip #46: Upgrading to a Newer Version * Upgrade applications and configuration from an earlier version* Upgrade Tool: Side-by-side upgrade– GUI: asupgrade– CLI: asupgrade --c– What happens ?* Copies older source domain -> target domain directory* asadmin start-domain --upgrade* Update Tool and pkg: In-place upgrade– GUI: updatetool, install all Available Updates– CLI: pkg image-update– Upgrade the domain* asadmin start-domain --upgradeTip #50: How to reach us?* GlassFish Forum: http://www.java.net/forums/glassfish/glassfish* [email protected]* @glassfish* facebook.com/glassfish* youtube.com/GlassFishVideos* blogs.oracle.com/theaquariumArun Gupta acknowledged that their method of presentation was experimental and actively solicited feedback about the session. The best way to reach them is on the GlassFish user forum.In addition, check out Gupta’s new book Java EE 6 Pocket Guide.

Perforce: File tampered with after resolve - edit or revert

- by fbrereto

I'm doing an integration in Perforce and am being met with the following: p4 integrate -1 -d -i -t -r -b my_branchspec //Foo/file.txt#6 - integrate from //Bar/file.txt#6 p4 resolve -am /Foo/file.txt - merging //Bar/file.txt#6 /Foo/file.txt tampered with before resolve - edit or revert. It seems no matter what I do, I am unable to make this issue go away: the next forward integration will show a similar message. The file is a text file. I can confirm that the MD5 hash for both files before the integration takes place is the same. What other issues might be going on with this file that I can resolve to fix this nagging message?

I"m using Windows Virtual PC on Windows 7 (host) running Windows XP (as the Guest O/S) I'm trying to get the Microphone working. When I Enable Integration Features: Microphone does not work When I run the Sound Recorder, the record button is disabled. If I look at Sound settings, there are no options for the Mic (it's all disabled "grayed out"). Speakers work Copy & Paste works When I Disable Integration Features: Microphone and speakers work Copy and Paste does not (as expected) Drag'n Drop copying does not work in either situation. What I've Tried Verified that the Windows XP Mode Virtual PC guest also has the same symptoms (Mic doesn't work) and audio out (speakers) do work. I"m going to try (but have little hope) to: -Uninstall and Reinstall the Integration addin for Virtual PC

Luminis and Google Apps Single Sign On

- by J.Zimmerman

We are a community college that is plodding forward with a Google Apps for Education implementation. There is support for Single Sign On and a fair amount of documentation for implementing it. We are looking to provide integration with our portal which is currently Luminis 3 (we are upgrading to Luminis 4 within a year). There is documentation available for Luminis specific integration, but apparently it is by request only. I have put the request in to SungardHE (where we license Luminis) and am waiting for a response. My questions are as follows... Is anyone here running Luminis? Have you tried to integrate it with a 3rd party email service like Google Apps for Education or Microsoft LiveEDU? If so, can you elaborate on implementation details above and beyond your Luminis installation and Google Apps setup? Looking for more of a general road map and differences between integration options with Luminis 3 and Luminis 4. Thanks!

A list of Entity Framework providers for various databases

- by Robert Koritnik

Which providers are there and your experience using them I would like to know about all possible native .net Framework Entity Framework providers that are out there as well as their limitations compared to the default Linq2Entities (from MS for MS SQL). If there are more for the same database even better. Tell me and I'll be updating this post with this list. Feel free to add additional providers directly into this post or provide an answer and others (including me) will add it to the list. Entity Framework 1 Microsoft SQL Server Standard/Enterprise/Express Linq 2 Entities - Microsoft SQL Server connector DataDirect ADO.NET Data Providers Microsoft SQL Server CE (Compact Edition) Any provider? MySQL MySQL Connector (since version 6.0) - I've read about issues when using Skip(), Take() and Sort() in the same expression tree - everyone welcome to input their experience/knowledge regarding this. (NOTE: MySQL Connector/NET Visual Studio Integration is not supported in the Express Editions of Visual Studio, meaning you won't be able to view MySQL databases in the Database explorer window or add a MySQL data source via Visual Studio wizard dialog boxes. Some users may find that this limits their ability to use Entity Framework and MySQL within Visual Studio Express). Devart dotConnect for MySQL - similar issues to MySql's connector as I've read and both try to blame MS for it [these issues are supposed to be solved] SQLite Devart dotConnect for SQLite System.Data.SQLite PostgreSQL Devart dotConnect for PostgreSQL Npgsql Oracle Devart dotConnect for Oracle Sample Entity Framework Provider for Oracle - community effort project DataDirect ADO.NET Data Providers DB2 IBM Data Server Provider has EF support.

Guides for PostgreSQL query tuning?

- by Joe

I've found a number of resources that talk about tuning the database server, but I haven't found much on the tuning of the individual queries. For instance, in Oracle, I might try adding hints to ignore indexes or to use sort-merge vs. correlated joins, but I can't find much on tuning Postgres other than using explicit joins and recommendations when bulk loading tables. Do any such guides exist so I can focus on tuning the most run and/or underperforming queries, hopefully without adversely affecting the currently well-performing queries? I'd even be happy to find something that compared how certain types of queries performed relative to other databases, so I had a better clue of what sort of things to avoid. update: I should've mentioned, I took all of the Oracle DBA classes along with their data modeling and SQL tuning classes back in the 8i days ... so I know about 'EXPLAIN', but that's more to tell you what's going wrong with the query, not necessarily how to make it better. (eg, are 'while var=1 or var=2' and 'while var in (1,2)' considered the same when generating an execution plan? What if I'm doing it with 10 permutations? When are multi-column indexes used? Are there ways to get the planner to optimize for fastest start vs. fastest finish? What sort of 'gotchas' might I run into when moving from mySQL, Oracle or some other RDBMS?) I could write any complex query dozens if not hundreds of ways, and I'm hoping to not have to try them all and find which one works best through trial and error. I've already found that 'SELECT count(*)' won't use an index, but 'SELECT count(primary_key)' will ... maybe a 'PostgreSQL for experienced SQL users' sort of document that explained sorts of queries to avoid, and how best to re-write them, or how to get the planner to handle them better. update 2: I found a Comparison of different SQL Implementations which covers PostgreSQL, DB2, MS-SQL, mySQL, Oracle and Informix, and explains if, how, and gotchas on things you might try to do, and his references section linked to Oracle / SQL Server / DB2 / Mckoi /MySQL Database Equivalents (which is what its title suggests) and to the wikibook SQL Dialects Reference which covers whatever people contribute (includes some DB2, SQLite, mySQL, PostgreSQL, Firebird, Vituoso, Oracle, MS-SQL, Ingres, and Linter).

Developer Laptop with SQL Server 2008 can't login to SSIS when offsite

- by wizlb

When I bring my Windows XP (SP3) laptop home I can still login as my domain account because Windows caches the info necessary to authenticate me when the domain controller isn't around. However, when I try to connect to Integration Services from within SQL Server Management Studio, it generates SSPI context errors. The only way it works is if I connect to the office with VPN or if I'm at the office where the domain controller is. I have both SQL Server Agent and SQL Server Integration Services 10 running under local computer accounts. It seems that the only option to connect to Integration Services from within Management Studio is to use Window authentication. Is there any way to do this when I'm not connected to the office? Why don't these services use the cached info just like Windows Login? Thanks.

Are government programming jobs good?

- by Absolute0

I am a passionate software developer and greatly enjoy programming. However I was recently contacted regarding a developer lead position for a government job at NYC for the fire department. The pay is pretty good, and I would assume the position has good job security and stability. But I am hesitant to even go for an interview as it seems like an exaggerated version of Office Space with a lot of Bureaucracy and mindless paper work. The description is as follows: The Lead Applications Developer, supporting the Programming Group, will be responsible for all phases of the system development life cycle including performing system analysis, requirements definition, database design, preparation of scopes of work, and development of project plans. Supervise programming staff and manage projects involving the design, implementation, maintenance, and enhancement of complex Oracle based user applications using Oracle Development tools. Applications will be deployed using Oracle Application Server utilizing programming languages such as JAVA, JSF, JSP, Oracle ADF, PL/SQL, and XML with J2EE and EJB technology. Anyone with previous government experience can share their two cents on this? Thank you.
