  • JAVA: POST data via HTTPS does not seem to get sent?

    - by ostollmann
    Hi guys (and girls), I have a problem POSTing data via HTTPS in Java. The server response is the same whether or not I send 'query'. Maybe someone can point out what the problem is... Thanks! Main class: package bind; public class Main { public static final String urlString = "https://www.sms.ethz.ch/cgi-bin/sms/send.pl"; public static void main(String[] args) { Message msg = new Message("Alles klar?"); URL url = new URL(urlString); String[][] values = new String[3][2]; values[0][0] = "action"; values[0][1] = "listoriginators"; values[1][0] = "username"; values[1][1] = "xxxxxx"; values[2][0] = "password"; values[2][1] = "xxxxxx"; Query query = new Query(values); System.out.println("Query: " + query.getQuery()); Request request = new Request(url.getURL(), query.getQuery()); } } Request class: package bind; public class Request { static private int ic = 0; private URL url; protected Request(java.net.URL URL, String query){ ic++; if(CONSTANTS.SHOW_LOGS) { System.out.println("log: new instance of 'Message'"); } // connect try { System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol"); java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider()); javax.net.ssl.HttpsURLConnection connection = (javax.net.ssl.HttpsURLConnection) URL.openConnection(); connection.setDoInput(true); connection.setDoOutput(true); connection.setRequestMethod("POST"); connection.setFollowRedirects(true); connection.setRequestProperty("Content-Length", String.valueOf(query.length())); connection.setRequestProperty("Content-Type", "application/x-www- form-urlencoded"); connection.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)"); java.io.DataOutputStream output = new java.io.DataOutputStream(connection.getOutputStream()); output.writeBytes(query); // <<-- NOTHING CHANGES IF I COMMENT THIS OUT OR NOT !!??!?! System.out.println("log: response code: " + connection.getResponseCode()); System.out.println("log: response message: " + connection.getResponseMessage()); java.io.DataInputStream input = new java.io.DataInputStream(connection.getInputStream()); for(int i = input.read(); i != -1; i = input.read()) { System.out.print((char)i); } System.out.print("\n"); input.close(); } catch(java.io.IOException e) { if(CONSTANTS.SHOW_LOGS) { System.out.println("error: unable to connect"); System.out.println(e); e.printStackTrace(); } } } } URL Class: public class URL { static private int ic = 0; private String URLString; private java.net.URL url; protected URL(String a_url){ ic++; if(CONSTANTS.SHOW_LOGS) { System.out.println("log: new instance of 'URL'"); } setURLString(a_url); createURL(); } private void setURLString(String a_url) { URLString = a_url; } private void createURL() { try { url = new java.net.URL(URLString); } catch(java.net.MalformedURLException e) { System.out.println("error: invalid URL"); System.out.println(e); e.printStackTrace(); } } private void showURL() { System.out.println("URL: " + url.getHost() + url.getPath()); } public java.net.URL getURL() { return url; } } PS: mostly from here: http://www.java-samples.com/java/POST-toHTTPS-url-free-java-sample-program.htm

  • "Local transaction already has 1 non-XA Resource: cannot add more resources" error

    - by jthg
    After reading previous questions about this error, it seems like all of them conclude that you need to enable XA on all of the data sources. But: What if I don't want a distributed transaction? What would I do if I want to start transactions on two different databases at the same time, but commit the transaction on one database and roll back the transaction on the other? I'm wondering how my code actually initiated a distributed transaction. It looks to me like I'm starting completely separate transactions on each of the databases. Info about the application: The application is an EJB running on a Sun Java Application Server 9.1 I use something like the following spring context to set up the hibernate session factories: <bean id="dbADatasource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="jdbc/dbA"/> </bean> <bean id="dbASessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dbADatasource" /> <property name="hibernateProperties"> [hibernate properties...] </property> <property name="mappingResources"> [mapping resources...] </property> </bean> <bean id="dbBDatasource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="jdbc/dbB"/> </bean> <bean id="dbBSessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dbBDatasource" /> <property name="hibernateProperties"> [hibernate properties...] </property> <property name="mappingResources"> [mapping resources...] </property> </bean> Both of the JNDI resources are javax.sql.ConnectionPoolDatasoure's. They actually both point to the same connection pool, but we have two different JNDI resources because there's the possibility that the two groups of tables will move to different databases in the future. Then in code, I do: sessionA = dbASessionFactory.openSession(); sessionB = dbBSessionFactory.openSession(); sessionA.beginTransaction(); sessionB.beginTransaction(); The sessionB.beginTransaction() line produces the error in the title of this post - sometimes. I ran the app on two different sun application servers. On one runs it fine, the other throws the error. I don't see any difference in how the two servers are configured although they do connect to different, but equivalent databases. So the question is Why doesn't the above code start completely independent transactions? How can I force it to start independent transactions rather than a distributed transaction? What configuration could cause the difference in behavior between the two application servers? Thanks.

  • Ant + JUnit: NoClassDefFoundError

    - by K-Boo
    Ok, I'm frustrated! I've hunted around for a good number of hours and am still stumped. Environment: WinXP, Eclipse Galileo 3.5 (straight install - no extra plugins). So, I have a simple JUnit test. It runs fine from it's internal Eclipse JUnit run configuration. This class has no dependencies on anything. To narrow this problem down as much as possible it simply contains: @Test public void testX() { assertEquals("1", new Integer(1).toString()); } No sweat so far. Now I want to take the super advanced step of running this test case from within Ant (the final goal is to integrate with Hudson). So, I create a build.xml: <project name="Test" default="basic"> <property name="default.target.dir" value="${basedir}/target" /> <property name="test.report.dir" value="${default.target.dir}/test-reports" /> <target name="basic"> <mkdir dir="${test.report.dir}" /> <junit fork="true" printSummary="true" showOutput="true"> <formatter type="plain" /> <classpath> <pathelement path="${basedir}/bin "/> </classpath> <batchtest fork="true" todir="${test.report.dir}" > <fileset dir="${basedir}/bin"> <include name="**/*Test.*" /> </fileset> </batchtest> </junit> </target> </project> ${basedir} is the Java project name in the workspace that contains the source, classes and build file. All .java's and the build.xml are in ${basedir}/src. The .class files are in ${basedir}/bin. I have added eclipse-install-dir/plugins/org.junit4_4.5.0.v20090423/junit.jar to the Ant Runtime Classpath via Windows / Preferences / Ant / Runtime / Contributed Entries. ant-junit.jar is in Ant Home Entries. So, what happens when I run this insanely complex target? My report file contains: Testsuite: com.xyz.test.RussianTest Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec Testcase: initializationError took 0 sec Caused an ERROR org/hamcrest/SelfDescribing java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$000(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) Caused by: java.lang.ClassNotFoundException: org.hamcrest.SelfDescribing at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) What is this org.hamcrest.SelfDescribing class? Something to do with mocks? OK, fine. But why the dependency? I'm not doing anything at all with it. This is literally a Java project with no dependencies other than JUnit. Stumped (and frustrated)!!

  • JNLP File Association: How do I open the file which was double-clicked on?

    - by Sam Barnum
    I've got the following JNLP: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE jnlp PUBLIC "-//Sun Microsystems, Inc//DTD JNLP Descriptor 6.0.10//EN" "http://java.sun.com/dtd/JNLP-6.0.10.dtd"> <jnlp spec="6.0.10" version="1.63" codebase="http://foo.example.com/msi" href="Foo.jnlp"> <information> <title>Foo</title> <vendor> Foo Systems, Inc.</vendor> <homepage href="http://Foo.com"/> <description>Foo Viewer/Editor Application</description> <icon href="splash.gif" width="425" height="102" kind="splash"/> <icon href="Foo.gif" width="64" height="64"/> <offline-allowed/> <shortcut> <desktop/> <menu submenu="Foo Systems, Inc."/> </shortcut> <association mime-type="application-x/wlog" extensions="wlog"/> <association mime-type="application-x/mplot" extensions="mplot"/> </information> <security> <all-permissions/> </security> <resources> <j2se version="1.6+" initial-heap-size="32m" max-heap-size="255m"/> <jar href="jars_deployment/TimingFramework-1.0.jar"/> <jar href="jars_deployment/iText-2.1.5.jar"/> <jar href="jars_deployment/jai_codec.jar"/> <jar href="Foo.jar"/> <jar href="jars_deployment/TimingFramework-1.0.jar"/> <jar href="jars_deployment/iText-2.1.5.jar"/> <jar href="jars_deployment/jai_codec.jar"/> <jar href="jars_deployment/jsch-20090402.jar"/> <property name="apple.laf.useScreenMenuBar" value="true"/> <property name="apple.awt.graphics.UseQuartz" value="false"/> <property name="com.apple.mrj.application.apple.menu.about.name" value="Foo"/> <property name="java.util.logging.config.file" value="/Users/Shared/logging.properties"/> </resources> <application-desc main-class="com.prosc.msi.editor.ui.test.Sandbox"/> </jnlp> Most everything is working. When I double-click a .wlog file, it opens up my application. However, it doesn't open the correct file. I read somewhere that JNLP was supposed to pass parameters to the main method indicating which file caused the app to be launched, but this is not happening (on OS X 10.6). I get an empty array to my application's main method. Probably unrelated, my splash screen doesn't work :( Any pointers on getting this working?

If i include the Jquery, then rich:hotkey not work. I am also Used , var $J = jQuery.noConflict(); . But this time also not work jQuery. I hope help me about this. Thanks for your effort.

  • ActiveRecord Logic Challenge - Smart Ways to Use AR Timestamp

    - by keruilin
    My question is somewhat specific to my app's issue, but the answer should be instructive in terms of use cases for association logic and the record timestamp. I have an NBA pick 'em game where I want to award badges for picking x number of games in a row correctly -- 10, 20, 30. Here are the models, attributes, and associations in-play: User id Pick id result # (values can be 'W', 'L', 'T', or nil. nil means hasn't resolved yet.) resolved # (values can be true, false, or nil.) game_time created_at *Note: There are cases where a pick's result field and resolved field will always be nil. Perhaps the game was cancelled. Badge id Award id user_id badge_id created_at User has many awards. User has many picks. Pick belongs to user. Badge has many awards. Award belongs to user. Award belongs to badge. One of the important rules here to capture in the code is that while a user can be awarded multiple streak badges (e.g., a user can win multiple 10-streak badges), the user CAN'T be awarded another badge for consecutive winning picks that were previously granted an award badge. One way to think of this is that all the dates of the winning picks must come after the date that the streak badge was awarded. For example, let's pretend that a user made 13 winning picks from May 5 to May 8, with the 10th winning pick occurring on May 7, and the last 3 on May 8. The user would be awarded a 10-streak badge on May 7. Now if the user makes another winning pick on May 9, the code must recognize that the user only has a streak of 4 winning picks, not 14, because the user already received an award for the first 10. Now let's assume that the user makes 6 more winning picks. In this case, the code must recognize that all winning picks since May 5 are eligible for a 20-streak badge award, and make the award. Another important rule is that when looking at a winning streak, we don't care about the game time, but rather when the pick was made (created_at). For example, let's say that Team A plays Team B on Sat. And Team C plays Team D on Sun. If the user picks Team C to beat Team D on Thurs, and Team A to beat Team C on Fri, and Team A wins on Sat, but Team C loses on Sun, then the user has a losing streak of 1. So when must the streak-check kick-in? As soon as a pick is a win. If it's a loss or tie, no point in checking. One more note: if the pick is not resolved (false) and the result is nil, that means the game was postponed and must be factored out. With all that said, what is the most efficient, effective and lean way to determine whether a user has a 10-, 20- or 30-win streak?

  • Deploying project, created with Eclipse and Maven, to Tomcat

    - by fatkh
    I'm using Eclipse 3.5, Maven 2, m2eclipse and Tomcat 6. So i create Maven project for archetype webapp. This is pom.xml: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.itransition</groupId> <artifactId>hello</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>hello Maven Webapp</name> <url>http://maven.apache.org</url> <!-- tools.jar dependency --> <profiles> <profile> <id>default-tools.jar</id> <activation> <property> <name>java.vendor</name> <value>Sun Microsystems Inc.</value> </property> </activation> <dependencies> <dependency> <groupId>com.sun</groupId> <artifactId>tools</artifactId> <version>1.5.0</version> <scope>system</scope> <systemPath>${java.home}/../lib/tools.jar</systemPath> </dependency> </dependencies> </profile> </profiles> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.1.8.1</version> </dependency> </dependencies> <build> <finalName>hello</finalName> </build> </project> So then i want to deploy my web application to Tomcat.

  • on Google App Engine 500 Error, it should be 200 instead of 500

  • Java saying XML Document Not Well Formed

    - by Pyroclastic
    Hey all. Java's XML parser seems to be thinking that my XML document is not well formed following the root element, but I've validated it with several tools and they all disagree. It's probably an error in my code rather than in the document itself, I'd really appreciate any help you all could offer me. Here is my Java method: private void loadFromXMLFile(File f) throws ParserConfigurationException, IOException, SAXException { File file = f; DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db; Document doc = null; db = dbf.newDocumentBuilder(); doc = db.parse(file); doc.getDocumentElement().normalize(); String desc = ""; String due = ""; String comment = ""; NodeList tasksList = doc.getElementsByTagName("task"); for (int i = 0; i < tasksList.getLength(); i++) { NodeList attributes = tasksList.item(i).getChildNodes(); for (int j = 0; i < attributes.getLength(); j++) { Node attribute = attributes.item(i); if (attribute.getNodeName() == "description") { desc = attribute.getTextContent(); } if (attribute.getNodeName() == "due") { due = attribute.getTextContent(); } if (attribute.getNodeName() == "comment") { comment = attribute.getTextContent(); } tasks.add(new Task(desc, due, comment)); } desc = ""; due = ""; comment = ""; } } And here is the XML file I'm trying to load: <?xml version="1.0"?> <tasklist> <task> <description>Task 1</description> <due>Due date 1</due> <comment>Comment 1</comment> <completed>false</completed> </task> <task> <description>Task 2</description> <due>Due date 2</due> <comment>Comment 2</comment> <completed>false</completed> </task> <task> <description>Task 3</description> <due>Due date 3</due> <comment>Comment 3</comment> <completed>true</completed> </task> </tasklist> And here is the error message java is throwing for me: run: [Fatal Error] tasks.xml:28:3: The markup in the document following the root element must be well-formed.

    I'm wanting to use Apache ActiveMQ on Ubuntu 12.04 LTS, but am running into what looks like a permissions problem when I try to run it as follows: edd:~$ sudo activemq --version INFO: Loading '/usr/share/activemq/activemq-options' INFO: Using java '/usr/lib/jvm/java-6-openjdk//bin/java' INFO: changing to user 'activemq' to invoke java Java Runtime: Sun Microsystems Inc. 1.6.0_24 /usr/lib/jvm/java-6-openjdk-amd64/jre Heap sizes: current=502464k free=499842k max=502464k JVM args: -Xms512M -Xmx512M -Dorg.apache.activemq.UseDedicatedTaskRunner=true -Dactivemq.classpath=/var/lib/activemq//conf;; -Dactivemq.home=/usr/share/activemq -Dactivemq.base=/var/lib/activemq/ ACTIVEMQ_HOME: /usr/share/activemq ACTIVEMQ_BASE: /var/lib/activemq ActiveMQ 5.5.0 For help or more information please see: http://activemq.apache.org edd:~$ sudo activemq start INFO: Loading '/usr/share/activemq/activemq-options' INFO: Using java '/usr/lib/jvm/java-6-openjdk//bin/java' INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details INFO: changing to user 'activemq' to invoke java -su: line 2: /var/run/activemq.pid: Permission denied INFO: pidfile created : '/var/run/activemq.pid' (pid '7811') edd:~$ sudo activemq status INFO: Loading '/usr/share/activemq/activemq-options' INFO: Using java '/usr/lib/jvm/java-6-openjdk//bin/java' ActiveMQ not running edd:~$ ps ax | grep 'activemq' 8040 pts/0 S+ 0:00 grep --color=auto activemq I installed ActiveMQ using sudo apt-get install activemq.

  • Ubuntu 12.04 on Amazon EC2: /dev/xvda1 will be checked for errors at next reboot?

    - by cwd
    I'm running the lastest Ubuntu 12.04 AMI (ami-a29943cb) from Canonical on Amazon EC2 and quite often when I log in I get the message: *** /dev/xvda1 will be checked for errors at next reboot *** I have read a bunch of documentation on this and seem to understand that every so many reboots (around 37 see Mount count / Maximum mount count below) Ubuntu wants to check a disk for errors. I can see that by using dumpe2fs -h /dev/xvda1 (reference) to get information such as: Last mounted on: / Filesystem UUID: 1ad27d06-4ecf-493d-bb19-4710c3caf924 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 524288 Block count: 2097152 Reserved block count: 104857 Free blocks: 1778055 Free inodes: 482659 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 511 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 512 Flex block group size: 16 Filesystem created: Tue Apr 24 03:07:48 2012 Last mount time: Thu Nov 8 03:17:58 2012 Last write time: Tue Apr 24 03:08:52 2012 Mount count: 3 Maximum mount count: 37 Last checked: Tue Apr 24 03:07:48 2012 Check interval: 15552000 (6 months) Next check after: Sun Oct 21 03:07:48 2012 Lifetime writes: 2454 MB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 Default directory hash: half_md4 Directory Hash Seed: 0a25e04c-6169-4d68-bfa6-a1acd8e39632 Journal backup: inode blocks Journal features: journal_incompat_revoke Journal size: 128M Journal length: 32768 Journal sequence: 0x0000158b Journal start: 1 I've tried these things to get rid of the message and usually the badblocks is what does it for me: Run this command and reboot: sudo touch /forcefsck Run badblocks to check the disk: badblocks /dev/sda1 Edit /etc/fstab and change the last "0" which is the fs_passno column accordingly and then reboot: The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno of 2. I don't understand: If this is a virtual drive shouldn't it be less prone to errors? Was the image created with one of the flags set? If not what is triggering it? Why is fs_passno set to 0 on Amazon EC2 Ubuntu images? This is not the first one that is like this.

  • APT: Hold packages back from updates without APT Pin

    - by David
    I know about pinning packages with APT; that's not what I want to do. Other questions have been answered with either using pinning or by using pins temporarily. I don't want to do this... What I want to do is keep packages back the same way the kernel has been: # apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done The following packages have been kept back: linux-generic-pae linux-headers-generic-pae linux-image-generic-pae The following packages will be upgraded: I want to add tomcat-* and mysql-* and sun-* to this list. In the past, there was a configuration parameter to do this - I've always thought it was something like Apt::Get::HoldPkgs or Apt::HoldPkgs but I can't find it. I want to have these packages held from updates until I specifically request them with an "apt-get install". I found the apt-get configuration Apt::NeverAutoRemove; will this do what I want? Added Question: I notice that Apt::NeverAutoRemove and Apt::Never-MarkAuto-Sections (among others) are not documented so far as I can see; they're not in the manpages. Neither is aptitude::Keep-Unused-Pattern and aptitude::Get-Root-Command. Is there any comprehensive and complete documentation for apt.conf?

  • Eclipse Execute from Home - Eclipse.org Version

    - by sayth
    Due to a lot of minor errors with the eclipse from the repository( cannot install mylyn or pydev due to unmet dependencies) I manually downloaded from eclipse.org.

From the command line I just get eclipse not installed use sudo apt-get to install it. I know I have java installed. sayth@sayth-TravelMate-5740G:~$ java -version java version "1.6.0_23" OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre10-0ubuntu5) OpenJDK Server VM (build 20.0-b11, mixed mode) how can I get eclipse to load normally?

  • Oracle Database 11g R2 támogatott SAP alatt is

    - by Lajos Sárecz
    Húsvét óta már SAP alatt is használható az Oracle Database 11g R2. Köztudott, hogy az SAP csak a Release 2-re ad ki támogatást, így ez most egy igazán örömteli hír az SAP felhasználóknak, hiszen az alábbi 11g R2 újdonságokat tudják alkalmazni SAP környezetben: • Advanced Compression opció (táblára, RMAN mentésre, expdp-re, Data Guard hálózatra) • Real Application Testing • Oracle Database 11g Release 2 Database Vault • Oracle Database 11g Release 2 RAC • Advanced Encryption táblaterekre, RMAN mentésekre, expdp-re, Data Guard hálózatra • Direct NFS • Deferred Segments • Online Patching Azaz például tömöríthetové válik az SAP adatbázisa, vagy az abból készített mentések. Az eddigi tapasztalatok szerint a tömörítés aránya adatbázistól függoen 2-4-szeres. Az adatbázis upgrade és minden egyéb adatbázis infrastruktúrát érinto változatatás kockázata jelentosen csökkentheto lesz a Real Application Testing alkalmazásával. A rendszergazdai szerepkörök szeparaláhatóvá válnak a Database Vault felhasználásával. A Real Application Clusters 11g R2 újdonságai is elérheto lesznek. A Transparent Data Encryption révén a táblaterek és a mentések titkosíthatók úgy, hogy az alkalmazás számára mindez transzparens, azonban a médiához közvetlenül hozzáférve nem lesznek visszafejthetok az adatok. Támogatott lesz a Direct NFS kliens, ezzel NFS elérési sebesség jelentosen javul. A Deffered Segments révén pedig a tábla szegmensek csak akkor kerülnek lefoglalásra, amikor adat kerül a táblába. Ez azért hasznos, mert általában alkalmazások telepítésekor létrejön minden tábla, azonban sok táblába nem kerül adat. Ezáltal mind a telepítés ideje, mind az adatbázis mérete csökkentheto. Az Online Patching pedig lehetové teszi a leállításmentes patch telepítést. Hát azt gondolom ezek vonzó lehetoségek, érdemes betervezni a közeljövobe az SAP rendszerek alatti adatbázis frissítését, hiszen a 10g verzió Premier Support idén nyáron lejár. Az upgrade-hez pedig mindenképp javaslom a Real Application Testing használatát, amivel az éles terhelés mellett teszthelheto teszt környezetben az upgrade. A Sun Oracle Database Machine és az Exadata sajnos még nem támogatott SAP alatt, mivel az ASM certifikáció még nem zárult le. A hírek szerint 2011 elejére várható, hogy ez megtörténik.

  • Jailbreak Your Kindle for Dead Simple Screensaver Customization

    - by Jason Fitzpatrick
    If you’re less than delighted with the default screensaver pack on the Kindle relief is just a simple hack and a reboot away. Read on to learn how to apply a painless jailbreak to your Kindle and create custom screensavers. Unlike jailbreaking other devices like the iPad and Android devices—which usually includes deep mucking about in the guts of your devices and the potential, however remote, for catastrophic bricking—jailbreaking the Kindle is not only extremely safe but Amazon, by releasing the Kindle sourcecode, has practically approved the process with a wink and a nod. Installing the jailbreak and the screensaver hack to replace the default screensavers is so simple we promise you’ll spend 1000% more time messing around making fun screensaver images than you will actually installing the hack. The default screensaver pack for the Amazon Kindle is a collection of 23 images that include portraits of famous authors, woodcarvings from centuries past, blueprints, book reliefs, and other suitably literature-oriented subjects. If you’re not a big fan of the pack—and we don’t blame you if, despite Emily Dickinson being your favorite single lady, you want to mix things up—it’s extremely simple to replace the default screen saver pack with as many custom images as your Kindle can hold. This hack works on every Kindle except the first generation; we’ll be demonstrating it on the brand new Kindle 3 with accompanying notes to direct users with older Kindles.

  • Oracle Database Security Protecting the Oracle IRM Schema

    - by Simon Thorpe
    Acquiring the Information Rights Management technology in 2006 was part of Oracle's strategic security vision and IRM compliments nicely the overall Oracle security set of solutions. A year ago I spoke about how Oracle has solutions that can help companies protect information throughout its entire life cycle. With our acquisition of Sun this set of solutions has solidified and has even extended down to the operating system and hardware level. Oracle can now offer customers technology that protects their data from the disk, through the database to documents on the desktop! With the recent release of Oracle IRM 11g I was tasked to configure demonstration and evaluation environments and I thought it would make a nice story to leverage some of the security features in the latest release of the Oracle Database. After building these environments I thought I would put together a simple video demonstrating how both Database Advanced Security and Information Rights Management combined can provide a very secure platform for protecting your information. Have a look at the following which highlights these database security options.Transparent Data Encryption protecting the communication from the Oracle IRM server to the Database server. Encryption techniques provide confidentiality and integrity of the data passing to and from the IRM service on the back end. Transparent Data Encryption protecting the Oracle IRM database schema. Encryption is used to provide confidentiality of the IRM data whilst it resides at rest in the database table space. Database Vault is used to ensure only the Oracle IRM service has access to query and update the information that resides in the database. This is an excellent method of ensuring that database administrators cannot look at or make changes to the Oracle IRM database whilst retaining their ability to administrate the database. The last thing you want after deploying an IRM solution is for a curious or unhappy DBA to run a query that grants them rights to your company financial data or documents pertaining to a merger or acquisition.
