  • Ops Center and Oracle Solaris 11

    - by user12609425
    There have been a few questions about Ops Center and S11 recently. People have been trying to discover and update S11 from Enterprise Controllers installed on S10 or Linux, and running into problems, and wondering what the solution is. Well, the solution is that, if you want to be able to discover, monitor, and update S11 OSes, you need to install your Enterprise Controller and at least one Proxy Controller on S11 systems. The Oracle Solaris and Linux install guides both note this in the chapters that cover preparing your environment. Technically, if you have an S11 Proxy Controller you can at least discover, manage, and monitor S11 systems. However, features like the automated installer and the image packaging system (for OS updates) can only be used through Ops Center if your Enterprise Controller is installed on S11 as well.

  • "bug" in C++11 text by Stroustrup?

    - by Astara
    I found an apparent contradiction in the c++ text having to do with the result of the c_str() function operating on std:strings (in my copy, the definition and contradiction are on p1040). First it defines the c_str() function as something that produces a 'C-style' (zero-terminated) string, but later it talks about how a C++ c_str value can have embed a 'C'-style, end-of-string terminators (i.e. NUL's) embedded in the string (that is defined by being NUL terminated). Um... does anyone else feel that this is a 'stretching' of the definition of a C-string beyond it's definition? I.e. I think what it means, is that if you were to look at the length() function as applied to the string, it will show a different end of string than using the C-definition of a z-string -- one that can contain any character except NUL, and is terminated by NUL. I likely don't have to worry about it in my of my programs, but it seems like a subtle distinction that makes a C++ c_str, not really a 'C'-string. Am I misunderstanding this issue? Thanks!

    - by Graham B
    can anyone please help. I've seen many people with the same problem and looked at all suggestions but still cannot get this to work. I have tried to unistall the application and install again, I have tried to change the version number and start again. I've debugged the code and it does go into the onCreate function, but when I go to make a select query it says the users table does not exist. Any help would greatly be appreciated. Thanks guys DatabaseHandler Class public class DatabaseHandler extends SQLiteOpenHelper { // Variables protected static final int DATABASE_VERSION = 1; protected static final String DATABASE_NAME = "MyUser.db"; // Constructor public DatabaseHandler(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } // Creating Tables @Override public void onCreate(SQLiteDatabase db) { // Create the Users table // NOTE: I have the column variables saved above String CREATE_USERS_TABLE = "CREATE TABLE IF NOT EXISTS Users(" + KEY_PRIMARY_ID + " " + INTEGER + " " + PRIMARY_KEY + " " + AUTO_INCREMENT + " " + NOT_NULL + "," + USERS_KEY_EMAIL + " " + NVARCHAR+"(1000)" + " " + UNIQUE + " " + NOT_NULL + "," + USERS_KEY_PIN + " " + NVARCHAR+"(10)" + " " + NOT_NULL + ")";

  • C++11: thread_local or array of OpenCL 1.2 cl_kernel objects?

    - by user926918
    I need to run several C++11 threads (GCC 4.7.1) parallely in host. Each of them needs to use a device, say a GPU. As per OpenCL 1.2 spec (p. 357): All OpenCL API calls are thread-safe75 except clSetKernelArg. clSetKernelArg is safe to call from any host thread, and is safe to call re-entrantly so long as concurrent calls operate on different cl_kernel objects. However, the behavior of the cl_kernel object is undefined if clSetKernelArg is called from multiple host threads on the same cl_kernel object at the same time. An elegant way would be to use thread_local cl_kernel objects and the other way I can think of is to use an array of these objects such that i'th thread uses i'th object. As I have not implemented these earlier I was wondering if any of the two are good or are there better ways of getting things done. TIA, S

  • Can I Have Polymorphic Containers With Value Semantics in C++11?

    - by John Dibling
    This is a sequel to a related post which asked the eternal question: Can I have polymorphic containers with value semantics in C++? The question was asked slightly incorrectly. It should have been more like: Can I have STL containers of a base type stored by-value in which the elements exhibit polymorphic behavior? If you are asking the question in terms of C++, the answer is "no." At some point, you will slice objects stored by-value. Now I ask the question again, but strictly in terms of C++11. With the changes to the language and the standard libraries, is it now possible to store polymorphic objects by value in an STL container? I'm well aware of the possibility of storing a smart pointer to the base class in the container -- this is not what I'm looking for, as I'm trying to construct objects on the stack without using new. Consider if you will (from the linked post) as basic C++ example: #include <iostream> using namespace std; class Parent { public: Parent() : parent_mem(1) {} virtual void write() { cout << "Parent: " << parent_mem << endl; } int parent_mem; }; class Child : public Parent { public: Child() : child_mem(2) { parent_mem = 2; } void write() { cout << "Child: " << parent_mem << ", " << child_mem << endl; } int child_mem; }; int main(int, char**) { // I can have a polymorphic container with pointer semantics vector<Parent*> pointerVec; pointerVec.push_back(new Parent()); pointerVec.push_back(new Child()); pointerVec[0]->write(); pointerVec[1]->write(); // Output: // // Parent: 1 // Child: 2, 2 // But I can't do it with value semantics vector<Parent> valueVec; valueVec.push_back(Parent()); valueVec.push_back(Child()); // gets turned into a Parent object :( valueVec[0].write(); valueVec[1].write(); // Output: // // Parent: 1 // Parent: 2 }

  • Oracle Solaris: Zones on Shared Storage

    - by Jeff Victor
    Oracle Solaris 11.1 has several new features. At oracle.com you can find a detailed list. One of the significant new features, and the most significant new feature releated to Oracle Solaris Zones, is casually called "Zones on Shared Storage" or simply ZOSS (rhymes with "moss"). ZOSS offers much more flexibility because you can store Solaris Zones on shared storage (surprise!) so that you can perform quick and easy migration of a zone from one system to another. This blog entry describes and demonstrates the use of ZOSS. ZOSS provides complete support for a Solaris Zone that is stored on "shared storage." In this case, "shared storage" refers to fiber channel (FC) or iSCSI devices, although there is one lone exception that I will demonstrate soon. The primary intent is to enable you to store a zone on FC or iSCSI storage so that it can be migrated from one host computer to another much more easily and safely than in the past. With this blog entry, I wanted to make it easy for you to try this yourself. I couldn't assume that you have a SAN available - which is a good thing, because neither do I! What could I use, instead? [There he goes, foreshadowing again... -Ed.] Developing this entry reinforced the lesson that the solution to every lab problem is VirtualBox. Oracle VM VirtualBox (its formal name) helps here in a couple of important ways. It offers the ability to easily install multiple copies of Solaris as guests on top of any popular system (Microsoft Windows, MacOS, Solaris, Oracle Linux (and other Linuxes) etc.). It also offers the ability to create a separate virtual disk drive (VDI) that appears as a local hard disk to a guest. This virtual disk can be moved very easily from one guest to another. In other words, you can follow the steps below on a laptop or larger x86 system. Please note that the ability to use ZOSS to store a zone on a local disk is very useful for a lab environment, but not so useful for production. I do not suggest regularly moving disk drives among computers. In the method I describe below, that virtual hard disk will contain the zone that will be migrated among the (virtual) hosts. In production, you would use FC or iSCSI LUNs instead. The zonecfg(1M) man page details the syntax for each of the three types of devices. Why Migrate? Why is the migration of virtual servers important? Some of the most common reasons are: Moving a workload to a different computer so that the original computer can be turned off for extensive maintenance. Moving a workload to a larger system because the workload has outgrown its original system. If the workload runs in an environment (such as a Solaris Zone) that is stored on shared storage, you can restore the service of the workload on an alternate computer if the original computer has failed and will not reboot. You can simplify lifecycle management of a workload by developing it on a laptop, migrating it to a test platform when it's ready, and finally moving it to a production system. Concepts For ZOSS, the important new concept is named "rootzpool". You can read about it in the zonecfg(1M) man page, but here's the short version: it's the backing store (hard disk(s), or LUN(s)) that will be used to make a ZFS zpool - the zpool that will hold the zone. This zpool: contains the zone's Solaris content, i.e. the root file system does not contain any content not related to the zone can only be mounted by one Solaris instance at a time Method Overview Here is a brief list of the steps to create a zone on shared storage and migrate it. The next section shows the commands and output. You will need a host system with an x86 CPU (hopefully at least a couple of CPU cores), at least 2GB of RAM, and at least 25GB of free disk space. (The steps below will not actually use 25GB of disk space, but I don't want to lead you down a path that ends in a big sign that says "Your HDD is full. Good luck!") Configure the zone on both systems, specifying the rootzpool that both will use. The best way is to configure it on one system and then copy the output of "zonecfg export" to the other system to be used as input to zonecfg. This method reduces the chances of pilot error. (It is not necessary to configure the zone on both systems before creating it. You can configure this zone in multiple places, whenever you want, and migrate it to one of those places at any time - as long as those systems all have access to the shared storage.) Install the zone on one system, onto shared storage. Boot the zone. Provide system configuration information to the zone. (In the Real World(tm) you will usually automate this step.) Shutdown the zone. Detach the zone from the original system. Attach the zone to its new "home" system. Boot the zone. The zone can be used normally, and even migrated back, or to a different system. Details The rest of this shows the commands and output. The two hostnames are "sysA" and "sysB". Note that each Solaris guest might use a different device name for the VDI that they share. I used the device names shown below, but you must discover the device name(s) after booting each guest. In a production environment you would also discover the device name first and then configure the zone with that name. Fortunately, you can use the command "zpool import" or "format" to discover the device on the "new" host for the zone. The first steps create the VirtualBox guests and the shared disk drive. I describe the steps here without demonstrating them. Download VirtualBox and install it using a method normal for your host OS. You can read the complete instructions. Create two VirtualBox guests, each to run Solaris 11.1. Each will use its own VDI as its root disk. Install Solaris 11.1 in each guest.Install Solaris 11.1 in each guest. To install a Solaris 11.1 guest, you can either download a pre-built VirtualBox guest, and import it, or install Solaris 11.1 from the "text install" media. If you use the latter method, after booting you will not see a windowing system. To install the GUI and other important things, login and run "pkg install solaris-desktop" and take a break while it installs those important things. Life is usually easier if you install the VirtualBox Guest Additions because then you can copy and paste between the host and guests, etc. You can find the guest additions in the folder matching the version of VirtualBox you are using. You can also read the instructions for installing the guest additions. To create the zone's shared VDI in VirtualBox, you can open the storage configuration for one of the two guests, select the SATA controller, and click on the "Add Hard Disk" icon nearby. Choose "Create New Disk" and specify an appropriate path name for the file that will contain the VDI. The shared VDI must be at least 1.5 GB. Note that the guest must be stopped to do this. Add that VDI to the other guest - using its Storage configuration - so that each can access it while running. The steps start out the same, except that you choose "Choose Existing Disk" instead of "Create New Disk." Because the disk is configured on both of them, VirtualBox prevents you from running both guests at the same time. Identify device names of that VDI, in each of the guests. Solaris chooses the name based on existing devices. The names may be the same, or may be different from each other. This step is shown below as "Step 1." Assumptions In the example shown below, I make these assumptions. The guest that will own the zone at the beginning is named sysA. The guest that will own the zone after the first migration is named sysB. On sysA, the shared disk is named /dev/dsk/c7t2d0 On sysB, the shared disk is named /dev/dsk/c7t3d0 (Finally!) The Steps Step 1) Determine the name of the disk that will move back and forth between the systems. root@sysA:~# format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c7t0d0 /pci@0,0/pci8086,2829@d/disk@0,0 1. c7t2d0 /pci@0,0/pci8086,2829@d/disk@2,0 Specify disk (enter its number): ^D Step 2) The first thing to do is partition and label the disk. The magic needed to write an EFI label is not overly complicated. root@sysA:~# format -e c7t2d0 selecting c7t2d0 [disk formatted] FORMAT MENU: ... format fdisk No fdisk table exists. The default partition for the disk is: a 100% "SOLARIS System" partition Type "y" to accept the default partition, otherwise type "n" to edit the partition table. n SELECT ONE OF THE FOLLOWING: ... Enter Selection: 1 ... G=EFI_SYS 0=Exit? f SELECT ONE... ... 6 format label ... Specify Label type[1]: 1 Ready to label disk, continue? y format quit root@sysA:~# ls /dev/dsk/c7t2d0 /dev/dsk/c7t2d0 Step 3) Configure zone1 on sysA. root@sysA:~# zonecfg -z zone1 Use 'create' to begin configuring a new zone. zonecfg:zone1 create create: Using system default template 'SYSdefault' zonecfg:zone1 set zonename=zone1 zonecfg:zone1 set zonepath=/zones/zone1 zonecfg:zone1 add rootzpool zonecfg:zone1:rootzpool add storage dev:dsk/c7t2d0 zonecfg:zone1:rootzpool end zonecfg:zone1 exit root@sysA:~# oot@sysA:~# zonecfg -z zone1 info zonename: zone1 zonepath: /zones/zone1 brand: solaris autoboot: false bootargs: file-mac-profile: pool: limitpriv: scheduling-class: ip-type: exclusive hostid: fs-allowed: anet: ... rootzpool: storage: dev:dsk/c7t2d0 Step 4) Install the zone. This step takes the most time, but you can wander off for a snack or a few laps around the gym - or both! (Just not at the same time...) root@sysA:~# zoneadm -z zone1 install Created zone zpool: zone1_rpool Progress being logged to /var/log/zones/zoneadm.20121022T163634Z.zone1.install Image: Preparing at /zones/zone1/root.

Then you can end the console session with the usual "~." incantation. Step 7) Shutdown the zone so it can be "moved." root@sysA:~# zoneadm -z zone1 shutdown Step 8) Detach the zone so that the original global zone can't use it. root@sysA:~# zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / solaris shared - zone1 installed /zones/zone1 solaris excl root@sysA:~# zpool list NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT rpool 17.6G 11.2G 6.47G 63% 1.00x ONLINE - zone1_rpool 1.98G 484M 1.51G 23% 1.00x ONLINE - root@sysA:~# zoneadm -z zone1 detach Exported zone zpool: zone1_rpool Step 9) Review the result and shutdown sysA so that sysB can use the shared disk. root@sysA:~# zpool list NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT rpool 17.6G 11.2G 6.47G 63% 1.00x ONLINE - root@sysA:~# zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / solaris shared - zone1 configured /zones/zone1 solaris excl root@sysA:~# init 0 Step 10) Now boot sysB and configure a zone with the parameters shown above in Step 1. (Again, the safest method is to use "zonecfg ... export" on sysA as described in section "Method Overview" above.) The one difference is the name of the rootzpool storage device, which was shown in the list of assumptions, and which you must determine by booting sysB and using the "format" or "zpool import" command. When that is done, you should see the output shown next.

Add space to the zone by adding a second storage device to the rootzpool. Make sure that you add it to the configurations of both zones! Create a new zone, specifying two disks in the rootzpool when you first configure the zone. When you install that zone, or clone it from another zone, zoneadm uses those two disks to create a mirrored pool.

  • Galaxy Tab 3 producing continuous LightSensor error in LogCat

    - by Richard Tingle
    I am using a Galaxy Tab 3 as a test device for writing an android app. As such I'm interested in the output of the LogCat which is being filled with these error level messages. The device itself appears to work correctly, apps which rely on the light sensor correctly respond to it and the number in the error itself goes down if the light sensor is obscured. If I wasn't using it to develop apps I wouldn't even be aware of the issue but I believe it is an issue with the device itself not my app: simply plugging the tab 3 into the computer and using Eclipse - ADT to look at the LogCat without any app running leads to these errors being shown. I know I could filter the LogCat to ignore these errors but inconvenience aside; they concern me. A sample of the log cat is below (it generates errors continuously). This is on verbose so it includes some debug level (D/) messages as well as the error level messages (E/). How can I correct the device to no longer generate these errors. 06-11 10:08:45.789: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:45.992: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.195: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.398: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.601: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:46.804: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.007: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.210: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.414: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.617: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:47.820: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.023: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.039: D/dalvikvm(15201): GC_CONCURRENT freed 1947K, 17% free 16973K/20359K, paused 13ms+13ms, total 50ms 06-11 10:08:48.226: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:48.429: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:48.632: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:48.632: D/STATUSBAR-NetworkController(472): refreshSignalCluster: data=0 bt=false 06-11 10:08:48.835: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.039: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.242: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.445: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13 06-11 10:08:49.632: D/STATUSBAR-NetworkController(472): refreshSignalCluster: data=0 bt=false 06-11 10:08:49.648: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 14 06-11 10:08:49.851: E/LightSensor(377): LightSensor::readEvents mPendingEvent.light = 13

  • Using backport-android-bluetooth on Android 1.6

    - by newth
    Hi, I'm trying to write an application using Bluetooth on Android 1.6. Since it's not officially supported, I found the backport of android.bluetooth API ( http://code.google.com/p/backport-android-bluetooth ). But when I deploy the sample chat application (modified for backport) LogCat gives me the error below: My question is, how I can use backport-android-bluetooth on 1.6 and is there any working samples? Thanks! 11-30 14:03:19.890: ERROR/AndroidRuntime(1927): Uncaught handler: thread main exiting due to uncaught exception 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): java.lang.ExceptionInInitializerError 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at backport.android.bluetooth.BluetoothSocket.<init>(BluetoothSocket.java:69) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at backport.android.bluetooth.BluetoothServerSocket.<init>(BluetoothServerSocket.java:16) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at backport.android.bluetooth.BluetoothAdapter.listenUsingRfcommWithServiceRecord(BluetoothAdapter.java:513) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at com.example.bluetooth.BluetoothChatService$AcceptThread.<init>(BluetoothChatService.java:237) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at com.example.bluetooth.BluetoothChatService.start(BluetoothChatService.java:109) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at com.example.bluetooth.BluetoothChat.onResume(BluetoothChat.java:138) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.app.Instrumentation.callActivityOnResume(Instrumentation.java:1225) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.app.Activity.performResume(Activity.java:3559) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2838) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:2866) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2420) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.app.ActivityThread.access$2100(ActivityThread.java:116) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1794) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.os.Handler.dispatchMessage(Handler.java:99) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.os.Looper.loop(Looper.java:123) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.app.ActivityThread.main(ActivityThread.java:4203) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at java.lang.reflect.Method.invokeNative(Native Method) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at java.lang.reflect.Method.invoke(Method.java:521) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at dalvik.system.NativeStart.main(Native Method) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): Caused by: java.lang.UnsatisfiedLinkError: classInitNative 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.bluetooth.RfcommSocket.classInitNative(Native Method) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): at android.bluetooth.RfcommSocket.<clinit>(RfcommSocket.java:152) 11-30 14:03:19.906: ERROR/AndroidRuntime(1927): ... 21 more

  • Problems with X11GraphicsDevice on Suse 11

    - by Daniel
    Hi, On servers running Suse 11 I'm experiencing hangups in sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) when connecting via Citrix (and setting DISPLAY to localhost:11.0). Running exactly the same code in exactly the same environment, excepth through Exceed (with DISPLAY set to my workstation's IP) it runs like clockwork. The error is not intermittent, it happens every time Reinstalling the OS does not help Can not reproduce it on Suse 10 This is what the main thread stack looks like: [junit] "main" prio=10 tid=0x0000000040112000 nid=0x6acc runnable [0x00002b9f909ae000] [junit] java.lang.Thread.State: RUNNABLE [junit] at sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) [junit] at sun.awt.X11GraphicsDevice.makeDefaultConfiguration(X11GraphicsDevice.java:208) [junit] at sun.awt.X11GraphicsDevice.getDefaultConfiguration(X11GraphicsDevice.java:182) [junit] - locked <0x00002b9fed6b8e70 (a java.lang.Object) [junit] at sun.awt.X11.XToolkit.(XToolkit.java:92) [junit] at java.lang.Class.forName0(Native Method) [junit] at java.lang.Class.forName(Class.java:169) [junit] at java.awt.Toolkit$2.run(Toolkit.java:834) [junit] at java.security.AccessController.doPrivileged(Native Method) [junit] at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:826) [junit] - locked <0x00002b9f94b8ada0 (a java.lang.Class for java.awt.Toolkit) [junit] at java.awt.Toolkit.getEventQueue(Toolkit.java:1676) [junit] at java.awt.EventQueue.invokeLater(EventQueue.java:954) [junit] at javax.swing.SwingUtilities.invokeLater(SwingUtilities.java:1264) ... Has anyone experienced something similar? Could this be a problem in Suse 11's display handling? I'm thankful for any input at this point - I'm fresh out of ideas :)

  • Virtual Networks in Oracle Solaris - Part 5

    - by user12616590
               A         long         time      ago in a    blogosphere   far, far away... I wrote four blog entries to describe the new network virtualization features that were in Solaris 11 Express: Part 1 introduced the concept of network virtualization and listed the basic virtual network elements. Part 2 expanded on the concepts and discussed the resource management features. Part 3 demonstrated the creation of some of these virtual network elements. Part 4 demonstrated the network resource controls. I had planned a final entry that added virtual routers to the list of virtual network elements, but Jeff McMeekin wrote a paper that discuses the same features. That paper is available at OTN. And this Jeff can't write any better than that Jeff... All of the features described in those blog entries and that paper are also available in Solaris 11. It is possible that some details have changed, but the vast majority of the content is unchanged.
