• Converting a PV vm back into an HVM vm

  - by wim.coekaerts

  I have been doing some Oracle VM benchmark stuff in the last week or 2 in my off hours and yesterday I wanted to convert one of my VMs that was based on a paravirt kernel into a vm that just boots as a regular hardware virt VM with a standard x86-64 kernel. It took me a little while to figure out the fastest way so now that I have it pretty much down I wanted to share the steps. A PV kernel uses pygrub and a paravirt kernel image that lives on the vm image virtual disk. since this disk image does not have to be bootable it doesn't contain a boot sector and if you just restart the VM in hvm mode the virtual bios will just not do much as it can't start the boot process from disk The first thing I do is make a backup of my vm.cfg file :-) and then edit it as follows : the original file contains : bootloader = '/usr/bin/pygrub' I replace that with : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' kernel = '/usr/lib/xen/boot/hvmloader' then changing the disk files. I change my xvd disks to hd disks and I copy over the iso image of my instal lDVD. In the case of my VM template it was based on OL5U4 So I downloaded Enterprise-R5-U4-Server-x86_64-dvd.iso and added it as a cd device. disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,xvda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,xvdb,w', ] to disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,hda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,hdb,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Enterprise-R5-U4-Server-x86_64-dvd.iso, hdc:cdrom,r', ] boot='d' for the network devices (vifs) I change : vif = ['bridge=xenbr2,type=netfront'] to vif = ['bridge=xenbr2,type=ioemu'] That should do it. Next, inside the VM, I copy over the regular kernel rpm that I want to end up running in hvm mode. In this example case it was : kernel-2.6.18-164.0.0.0.1.el5.x8664.rpm. I will use that later on in the process. I put this kernel simply in /root At this point I just start the vm with xm create vm.cfg and start my vnc console to the vm console. Oracle Linux will boot from the iso image, I just go through the install steps and click on UPgrade existing (not re-install). Because the VM is the same as the ISO the install won't actually do anything and it will run through instantly. When the "Reboot" button pops up, don't reboot. Switch to the command prompt console. hi alt-f2 to go to the shell prompt. Now it's easy : umount /mnt/sysimage/boot cd /mnt/sysimage chroot . mount /dev/hda1 (if that was your /boot partition) export PATH=/sbin:$PATH (just to clean that up) edit /etc/modprobe.conf and comment out the xen modules (just put a # in front) Install grub. if your /boot is hda1 then that is (hd0,0) $ grub root (hd0,0) setup (hd0) exit grub now you have a good bootsector, grub installed and you have your grub.conf file Install the new kernel cd root (this is your old /root in your pv image) rpm -ivh remove (or comment out) boot='d' in your vm.cfg restart the VM and you should be good to go, regular grub should start and load your environment. Caveats : this assumes you used labels for your filesystems. if /etc/fstab were to have devices listed then you would have to rename these device before rebooting as well. If you had a /dev/xvda disk then this would be /dev/hda or /dev/sda. All in all it is a relatively short and simple process.

• Solaris 11.1: Encrypted Immutable Zones on (ZFS) Shared Storage

  - by darrenm

  Solaris 11 brought both ZFS encryption and the Immutable Zones feature and I've talked about the combination in the past.  Solaris 11.1 adds a fully supported method of storing zones in their own ZFS using shared storage so lets update things a little and put all three parts together. When using an iSCSI (or other supported shared storage target) for a Zone we can either let the Zones framework setup the ZFS pool or we can do it manually before hand and tell the Zones framework to use the one we made earlier.  To enable encryption we have to take the second path so that we can setup the pool with encryption before we start to install the zones on it. We start by configuring the zone and specifying an rootzpool resource: # zonecfg -z eizoss Use 'create' to begin configuring a new zone. zonecfg:eizoss> create create: Using system default template 'SYSdefault' zonecfg:eizoss> set zonepath=/zones/eizoss zonecfg:eizoss> set file-mac-profile=fixed-configuration zonecfg:eizoss> add rootzpool zonecfg:eizoss:rootzpool> add storage \ iscsi://zs7120-tvp540-c.uk.oracle.com/luname.naa.600144f09acaacd20000508e64a70001 zonecfg:eizoss:rootzpool> end zonecfg:eizoss> verify zonecfg:eizoss> commit zonecfg:eizoss> Now lets create the pool and specify encryption: # suriadm map \ iscsi://zs7120-tvp540-c.uk.oracle.com/luname.naa.600144f09acaacd20000508e64a70001 PROPERTY VALUE mapped-dev /dev/dsk/c10t600144F09ACAACD20000508E64A70001d0 # echo "zfscrypto" > /zones/p # zpool create -O encryption=on -O keysource=passphrase,file:///zones/p eizoss \ /dev/dsk/c10t600144F09ACAACD20000508E64A70001d0 # zpool export eizoss Note that the keysource example above is just for this example, realistically you should probably use an Oracle Key Manager or some other better keystorage, but that isn't the purpose of this example.  Note however that it does need to be one of file:// https:// pkcs11: and not prompt for the key location.  Also note that we exported the newly created pool.  The name we used here doesn't actually mater because it will get set properly on import anyway. So lets go ahead and do our install: zoneadm -z eizoss install -x force-zpool-import Configured zone storage resource(s) from: iscsi://zs7120-tvp540-c.uk.oracle.com/luname.naa.600144f09acaacd20000508e64a70001 Imported zone zpool: eizoss_rpool Progress being logged to /var/log/zones/zoneadm.20121029T115231Z.eizoss.install Image: Preparing at /zones/eizoss/root. AI Manifest: /tmp/manifest.xml.ujaq54 SC Profile: /usr/share/auto_install/sc_profiles/enable_sci.xml Zonename: eizoss Installation: Starting ...

Done: Installation completed in 929.606 seconds. Next Steps: Boot the zone, then log into the zone console (zlogin -C) to complete the configuration process. Log saved in non-global zone as /zones/eizoss/root/var/log/zones/zoneadm.20121029T115231Z.eizoss.install That was really all we had to do, when the install is done boot it up as normal. The zone administrator has no direct access to the ZFS wrapping keys used for the encrypted pool zone is stored on.  Due to how inheritance works in ZFS he can still create new encrypted datasets that use those wrapping keys (without them ever being inside a process in the zone) or he can create encrypted datasets inside the zone that use keys of his own choosing, the output below shows the two cases: rpool is inheriting the key material from the global zone (note we can see the value of the keysource property but we don't use it inside the zone nor does that path need to be (or is) accessible inside the zone). Whereas rpool/export/home/bob has set keysource locally. # zfs get encryption,keysource rpool rpool/export/home/bob NAME PROPERTY VALUE SOURCE rpool encryption on inherited from $globalzone rpool keysource passphrase,file:///zones/p inherited from $globalzone rpool/export/home/bob encryption on local rpool/export/home/bob keysource passphrase,prompt local

• Server-Sent Events using GlassFish (TOTD #179)

  - by arungupta

  Bhakti blogged about Server-Sent Events on GlassFish and I've been planning to try it out for past some days. Finally, I took some time out today to learn about it and build a simplistic example showcasing the touch points. Server-Sent Events is developed as part of HTML5 specification and provides push notifications from a server to a browser client in the form of DOM events. It is defined as a cross-browser JavaScript API called EventSource. The client creates an EventSource by requesting a particular URL and registers an onmessage event listener to receive the event notifications. This can be done as shown var url = 'http://' + document.location.host + '/glassfish-sse/simple';eventSource = new EventSource(url);eventSource.onmessage = function (event) { var theParagraph = document.createElement('p'); theParagraph.innerHTML = event.data.toString(); document.body.appendChild(theParagraph);} This code subscribes to a URL, receives the data in the event listener, adds it to a HTML paragraph element, and displays it in the document. This is where you'll parse JSON and other processing to display if some other data format is received from the URL. The URL to which the EventSource is subscribed to is updated on the server side and there are multipe ways to do that. GlassFish 4.0 provide support for Server-Sent Events and it can be achieved registering a handler as shown below: @ServerSentEvent("/simple")public class MySimpleHandler extends ServerSentEventHandler { public void sendMessage(String data) { try { connection.sendMessage(data); } catch (IOException ex) { . . . } }} And then events can be sent to this handler using a singleton session bean as shown: @Startup@Statelesspublic class SimpleEvent { @Inject @ServerSentEventContext("/simple") ServerSentEventHandlerContext<MySimpleHandler> simpleHandlers; @Schedule(hour="*", minute="*", second="*/10") public void sendDate() { for(MySimpleHandler handler : simpleHandlers.getHandlers()) { handler.sendMessage(new Date().toString()); } }} This stateless session bean injects ServerSentEventHandlers listening on "/simple" path. Note, there may be multiple handlers listening on this path. The sendDate method triggers every 10 seconds and send the current timestamp to all the handlers. The client side browser simply displays the string. The HTTP request headers look like: Accept: text/event-streamAccept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3Accept-Encoding: gzip,deflate,sdchAccept-Language: en-US,en;q=0.8Cache-Control: no-cacheConnection: keep-aliveCookie: JSESSIONID=97ff28773ea6a085e11131acf47bHost: localhost:8080Referer: http://localhost:8080/glassfish-sse/faces/index2.xhtmlUser-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.54 Safari/536.5 And the response headers as: Content-Type: text/event-streamDate: Thu, 14 Jun 2012 21:16:10 GMTServer: GlassFish Server Open Source Edition 4.0Transfer-Encoding: chunkedX-Powered-By: Servlet/3.0 JSP/2.2 (GlassFish Server Open Source Edition 4.0 Java/Apple Inc./1.6) Notice, the MIME type of the messages from server to the client is text/event-stream and that is defined by the specification. The code in Bhakti's blog can be further simplified by using the recently-introduced Twitter API for Java as shown below: @Schedule(hour="*", minute="*", second="*/10") public void sendTweets() { for(MyTwitterHandler handler : twitterHandler.getHandlers()) { String result = twitter.search("glassfish", String.class); handler.sendMessage(result); }} The complete source explained in this blog can be downloaded here and tried on GlassFish 4.0 build 34. The latest promoted build can be downloaded from here and the complete source code for the API and implementation is here. I tried this sample on Chrome Version 19.0.1084.54 on Mac OS X 10.7.3.

• The five steps of business intelligence adoption: where are you?

  - by Red Gate Software BI Tools Team

  When I was in Orlando and New York last month, I spoke to a lot of business intelligence users. What they told me suggested a path of BI adoption. The user’s place on the path depends on the size and sophistication of their organisation. Step 1: A company with a database of customer transactions will often want to examine particular data, like revenue and unit sales over the last period for each product and territory. To do this, they probably use simple SQL queries or stored procedures to produce data on demand. Step 2: The results from step one are saved in an Excel document, so business users can analyse them with filters or pivot tables. Alternatively, SQL Server Reporting Services (SSRS) might be used to generate a report of the SQL query for display on an intranet page. Step 3: If these queries are run frequently, or business users want to explore data from multiple sources more freely, it may become necessary to create a new database structured for analysis rather than CRUD (create, retrieve, update, and delete). For example, data from more than one system — plus external information — may be incorporated into a data warehouse. This can become ‘one source of truth’ for the business’s operational activities. The warehouse will probably have a simple ‘star’ schema, with fact tables representing the measures to be analysed (e.g. unit sales, revenue) and dimension tables defining how this data is aggregated (e.g. by time, region or product). Reports can be generated from the warehouse with Excel, SSRS or other tools. Step 4: Not too long ago, Microsoft introduced an Excel plug-in, PowerPivot, which allows users to bring larger volumes of data into Excel documents and create links between multiple tables.  These BISM Tabular documents can be created by the database owners or other expert Excel users and viewed by anyone with Excel PowerPivot. Sometimes, business users may use PowerPivot to create reports directly from the primary database, bypassing the need for a data warehouse. This can introduce problems when there are misunderstandings of the database structure or no single ‘source of truth’ for key data. Step 5: Steps three or four are often enough to satisfy business intelligence needs, especially if users are sophisticated enough to work with the warehouse in Excel or SSRS. However, sometimes the relationships between data are too complex or the queries which aggregate across periods, regions etc are too slow. In these cases, it can be necessary to formalise how the data is analysed and pre-build some of the aggregations. To do this, a business intelligence professional will typically use SQL Server Analysis Services (SSAS) to create a multidimensional model — or “cube” — that more simply represents key measures and aggregates them across specified dimensions. Step five is where our tool, SSAS Compare, becomes useful, as it helps review and deploy changes from development to production. For us at Red Gate, the primary value of SSAS Compare is to establish a dialog with BI users, so we can develop a portfolio of products that support creation and deployment across a range of report and model types. For example, PowerPivot and the new BISM Tabular model create a potential customer base for tools that extend beyond BI professionals. We’re interested in learning where people are in this story, so we’ve created a six-question survey to find out. Whether you’re at step one or step five, we’d love to know how you use BI so we can decide how to build tools that solve your problems. So if you have a sixty seconds to spare, tell us on the survey!

• Auto-organized / smart inventory system?

  - by VeXe

  for the past week I've been working on an inventory system with Unity3D. At first I got help from the guys at Design3 but it wasn't too long till we split path, because I really didn't like the way they did their code, it didn't have any smell of OOP whatsoever. I took it further steps ahead - items take more than one slot, advanced placement system (items tries their best to find the best close fit), local mouse system (mouse gets trapped in active bag area), etc. Here's a demo of my work. What we would like to have in our game, is an auto-organizing feature - not auto-sort. We want this feature because our inventory's going to be in 'real-time' - not like in Resident Evil 1,2,3 etc where you would pause the game and do things in your inventory. Now imagine your self in a sticky situation surrounded by zombies, and you don't have bullets, you look around, you see that there are bullets nearby on the ground, so you go for them and try to pick them up, but they don't fit! you look at your inventory and find out that if you reorganize some of the items, it will fit! - now the player - in that situation doesn't have time to reorganize because he's surrounded with zombies and will die if he stops and organizes the inventory to make space (remember inventory in real-time, no pausing) - wouldn't it be nice for that to happen automatically? - Yes! (I believe this has been implemented in some games like Dungeon siege or something, so sure it's doable) take a look at this picture for example: Yes, so if you auto-sort the issue you will get your spaces but it's bad because: 1- Expensive: it doesn't need a whole sort operation to free those spaces, in the first picture, just slide the red item at the bottom to the very left, and you get the same spaces that you got from the auto-sort. 2- It's annoying to the player: "Who the F told you to re-order my stuff?" I'm not asking for "How to write the code" for this, I'm just asking for some guidance, where to look, what algorithms are involved? Is this something related to graphs and shortest path stuff? I hope not cuz I didn't manage to continue my college studies :/ But even if it is, just tell me and I will learn the stuff related. Notice there could be more than just one solution. So I guess the first thing I have to do is figure out if the situation is 'solvable' - if I know how to determine if a situation is solvable or not, then I can 'solve' it. I just need to know the conditions that makes it 'solvable'. And I believe there must be some algorithm/data structure for this. Here's a pic for more than one solution of trying to fit a 1x3 item: The arrows show just one of the solutions, but if you look you will find more than one. This is what I ultimately not auto-sorting but find a solution and applying it. Note that if I spend time on it I will come up with a way to solve it, but it wouldn't be the best way, it's like, holding a car wheel with your feet instead of your hands! XD Or just like trying to solve an issue that requires arrays, but you're not yet aware of their existence! So what is the right approach to this? Hope somebody helps, thanks a lot in advance :)

  Very interesting thing and handy to know when needed is the fact that "menuText" and "popupText" (from org.openide.awt.ActionRegistration) can be changed dynamically, via "putValue" as shown below for "popupText". The Action class, in this case, needs to be eager, hence you won't receive the object of interest via the constructor, but you can easily use the global Lookup for that purpose instead, as also shown below. import java.awt.event.ActionEvent; import java.text.DateFormat; import java.text.SimpleDateFormat; import javax.swing.AbstractAction; import org.netbeans.api.project.Project; import org.netbeans.api.project.ProjectInformation; import org.netbeans.api.project.ProjectUtils; import org.openide.awt.ActionID; import org.openide.awt.ActionReference; import org.openide.awt.ActionRegistration; import org.openide.util.Utilities; @ActionID( category = "Project", id = "org.ptt.DemoProjectAction") @ActionRegistration( lazy = false, displayName = "NOT-USED") @ActionReference(path = "Projects/Actions", position = 0) public final class DemoProjectAction extends AbstractAction{ private final ProjectInformation context; public DemoProjectAction() { putValue("popupText", "Select Me To See Current Time!"); context = ProjectUtils.getInformation( Utilities.actionsGlobalContext().lookup(Project.class)); } @Override public void actionPerformed(ActionEvent e) { refresh(); } protected void refresh() { DateFormat formatter = new SimpleDateFormat("HH:mm:ss"); String formatted = formatter.format(System.currentTimeMillis()); putValue("popupText", "Time: " + formatted + " (" + context.getDisplayName() +")"); } } Now, let's do something semi useful and display, in the popup, which is available when you right-click a project, the time since the last change was made anywhere in the project, i.e., we can listen recursively to any changes done within a project and then update the popup with the newly acquired information, dynamically: import java.awt.event.ActionEvent; import java.text.DateFormat; import java.text.SimpleDateFormat; import javax.swing.AbstractAction; import org.netbeans.api.project.Project; import org.netbeans.api.project.ProjectUtils; import org.openide.awt.ActionID; import org.openide.awt.ActionReference; import org.openide.awt.ActionRegistration; import org.openide.filesystems.FileAttributeEvent; import org.openide.filesystems.FileChangeListener; import org.openide.filesystems.FileEvent; import org.openide.filesystems.FileRenameEvent; import org.openide.util.Utilities; @ActionID( category = "Project", id = "org.ptt.TrackProjectTimerAction") @ActionRegistration( lazy = false, displayName = "NOT-USED") @ActionReference( path = "Projects/Actions", position = 0) public final class TrackProjectTimerAction extends AbstractAction implements FileChangeListener { private final Project context; private Long startTime; private Long changedTime; private DateFormat formatter; public TrackProjectTimerAction() { putValue("popupText", "Enable project time tracker"); this.formatter = new SimpleDateFormat("HH:mm:ss"); context = Utilities.actionsGlobalContext().lookup(Project.class); context.getProjectDirectory().addRecursiveListener(this); } @Override public void actionPerformed(ActionEvent e) { startTimer(); } protected void startTimer() { startTime = System.currentTimeMillis(); String formattedStartTime = formatter.format(startTime); putValue("popupText", "Timer started: " + formattedStartTime + " (" + ProjectUtils.getInformation(context).getDisplayName() + ")"); } @Override public void fileChanged(FileEvent fe) { changedTime = System.currentTimeMillis(); formatter = new SimpleDateFormat("mm:ss"); String formattedLapse = formatter.format(changedTime - startTime); putValue("popupText", "Time since last change: " + formattedLapse + " (" + ProjectUtils.getInformation(context).getDisplayName() + ")"); startTime = changedTime; } @Override public void fileFolderCreated(FileEvent fe) {} @Override public void fileDataCreated(FileEvent fe) {} @Override public void fileDeleted(FileEvent fe) {} @Override public void fileRenamed(FileRenameEvent fre) {} @Override public void fileAttributeChanged(FileAttributeEvent fae) {} }

• Using WKA in Large Coherence Clusters (Disabling Multicast)

  - by jpurdy

  Disabling hardware multicast (by configuring well-known addresses aka WKA) will place significant stress on the network. For messages that must be sent to multiple servers, rather than having a server send a single packet to the switch and having the switch broadcast that packet to the rest of the cluster, the server must send a packet to each of the other servers. While hardware varies significantly, consider that a server with a single gigabit connection can send at most ~70,000 packets per second. To continue with some concrete numbers, in a cluster with 500 members, that means that each server can send at most 140 cluster-wide messages per second. And if there are 10 cluster members on each physical machine, that number shrinks to 14 cluster-wide messages per second (or with only mild hyperbole, roughly zero). It is also important to keep in mind that network I/O is not only expensive in terms of the network itself, but also the consumption of CPU required to send (or receive) a message (due to things like copying the packet bytes, processing a interrupt, etc). Fortunately, Coherence is designed to rely primarily on point-to-point messages, but there are some features that are inherently one-to-many: Announcing the arrival or departure of a member Updating partition assignment maps across the cluster Creating or destroying a NamedCache Invalidating a cache entry from a large number of client-side near caches Distributing a filter-based request across the full set of cache servers (e.g. queries, aggregators and entry processors) Invoking clear() on a NamedCache The first few of these are operations that are primarily routed through a single senior member, and also occur infrequently, so they usually are not a primary consideration. There are cases, however, where the load from introducing new members can be substantial (to the point of destabilizing the cluster). Consider the case where cluster in the first paragraph grows from 500 members to 1000 members (holding the number of physical machines constant). During this period, there will be 500 new member introductions, each of which may consist of several cluster-wide operations (for the cluster membership itself as well as the partitioned cache services, replicated cache services, invocation services, management services, etc). Note that all of these introductions will route through that one senior member, which is sharing its network bandwidth with several other members (which will be communicating to a lesser degree with other members throughout this process). While each service may have a distinct senior member, there's a good chance during initial startup that a single member will be the senior for all services (if those services start on the senior before the second member joins the cluster). It's obvious that this could cause CPU and/or network starvation. In the current release of Coherence (3.7.1.3 as of this writing), the pure unicast code path also has less sophisticated flow-control for cluster-wide messages (compared to the multicast-enabled code path), which may also result in significant heap consumption on the senior member's JVM (from the message backlog). This is almost never a problem in practice, but with sufficient CPU or network starvation, it could become critical. For the non-operational concerns (near caches, queries, etc), the application itself will determine how much load is placed on the cluster. Applications intended for deployment in a pure unicast environment should be careful to avoid excessive dependence on these features. Even in an environment with multicast support, these operations may scale poorly since even with a constant request rate, the underlying workload will increase at roughly the same rate as the underlying resources are added. Unless there is an infrastructural requirement to the contrary, multicast should be enabled. If it can't be enabled, care should be taken to ensure the added overhead doesn't lead to performance or stability issues. This is particularly crucial in large clusters.

• Why is this beat detection code failing to register some beats properly?

  - by Quincy

  I made this SoundAnalyzer class to detect beats in songs: class SoundAnalyzer { public SoundBuffer soundData; public Sound sound; public List<double> beatMarkers = new List<double>(); public SoundAnalyzer(string path) { soundData = new SoundBuffer(path); sound = new Sound(soundData); } // C = threshold, N = size of history buffer / 1024 B = bands public void PlaceBeatMarkers(float C, int N, int B) { List<double>[] instantEnergyList = new List<double>[B]; GetEnergyList(B, ref instantEnergyList); for (int i = 0; i < B; i++) { PlaceMarkers(instantEnergyList[i], N, C); } beatMarkers.Sort(); } private short[] getRange(int begin, int end, short[] array) { short[] result = new short[end - begin]; for (int i = 0; i < end - begin; i++) { result[i] = array[begin + i]; } return result; } // get a array of with a list of energy for each band private void GetEnergyList(int B, ref List<double>[] instantEnergyList) { for (int i = 0; i < B; i++) { instantEnergyList[i] = new List<double>(); } short[] samples = soundData.Samples; float timePerSample = 1 / (float)soundData.SampleRate; int sampleIndex = 0; int nextSamples = 1024; int samplesPerBand = nextSamples / B; // for the whole song while (sampleIndex + nextSamples < samples.Length) { complex[] FFT = FastFourier.Calculate(getRange(sampleIndex, nextSamples + sampleIndex, samples)); // foreach band for (int i = 0; i < B; i++) { double energy = 0; for (int j = 0; j < samplesPerBand; j++) energy += FFT[i * samplesPerBand + j].GetMagnitude(); energy /= samplesPerBand; instantEnergyList[i].Add(energy); } if (sampleIndex + nextSamples >= samples.Length) nextSamples = samples.Length - sampleIndex - 1; sampleIndex += nextSamples; samplesPerBand = nextSamples / B; } } // place the actual markers private void PlaceMarkers(List<double> instantEnergyList, int N, float C) { double timePerSample = 1 / (double)soundData.SampleRate; int index = N; int numInBuffer = index; double historyBuffer = 0; //Fill the history buffer with n * instant energy for (int i = 0; i < index; i++) { historyBuffer += instantEnergyList[i]; } // If instantEnergy / samples in buffer < instantEnergy for the next sample then add beatmarker. while (index + 1 < instantEnergyList.Count) { if(instantEnergyList[index + 1] > (historyBuffer / numInBuffer) * C) beatMarkers.Add((index + 1) * 1024 * timePerSample); historyBuffer -= instantEnergyList[index - numInBuffer]; historyBuffer += instantEnergyList[index + 1]; index++; } } } For some reason it's only detecting beats from 637 sec to around 641 sec, and I have no idea why. I know the beats are being inserted from multiple bands since I am finding duplicates, and it seems that it's assigning a beat to each instant energy value in between those values. It's modeled after this: http://www.flipcode.com/misc/BeatDetectionAlgorithms.pdf So why won't the beats register properly?

• Instead of the specified Texture, black circles on a green background are getting rendered. Why?

  - by vinzBad

  I'm trying to render a Texture via OpenGL. But instead of the texture black circles on a green background are rendered. (They scale, depending what the rotation of the texture is) Example: The texture I'm trying to render is the following: This is the code I use to render the texture, it's located in my Sprite-class. public void Render() { Matrix4 matrix = Matrix4.CreateTranslation(-OriginX, -OriginY, 0) * Matrix4.CreateRotationZ(Rotation) * Matrix4.CreateTranslation(X, Y, 0); Vector2[] corners = { new Vector2(0,0), //top left new Vector2(Width ,0),//top right new Vector2(Width,Height),//bottom rigth new Vector2(0,Height)//bottom left }; //copy the corners to the uv coordinates Vector2[] uv = corners.ToArray<Vector2>(); //transform the coordinates for (int i = 0; i < 4; i++) corners[i] = new Vector2(Vector3.Transform(new Vector3(corners[i]), matrix)); //GL.Color3(TintColor); GL.BindTexture(TextureTarget.Texture2D, _ID); GL.Begin(BeginMode.Quads); { for (int i = 0; i < 4; i++) { GL.TexCoord2(uv[i]); GL.Vertex3(corners[i].X, corners[i].Y, _layerDepth); } } GL.End(); if (EnableDebugDraw) { GL.Color3(Color.Violet); GL.PointSize(3); GL.Begin(BeginMode.Points); { for (int i = 0; i < 4; i++) GL.Vertex2(corners[i]); } GL.End(); GL.Color3(Color.Green); GL.Begin(BeginMode.Points); GL.Vertex2(X, Y); GL.End(); } } This is how I setup OpenGL. public static void SetupGL() { GL.Enable(EnableCap.AlphaTest); GL.AlphaFunc(AlphaFunction.Greater, 0.1f); GL.Enable(EnableCap.Texture2D); GL.Hint(HintTarget.PerspectiveCorrectionHint, HintMode.Nicest); } With this function I load the texture: public static uint LoadTexture(string path) { uint id; GL.GenTextures(1, out id); GL.BindTexture(TextureTarget.Texture2D, id); Bitmap bitmap = new Bitmap(path); BitmapData data = bitmap.LockBits(new System.Drawing.Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly, System.Drawing.Imaging.PixelFormat.Format32bppArgb); GL.TexImage2D(TextureTarget.Texture2D, 0, PixelInternalFormat.Rgba, data.Width, data.Height, 0, OpenTK.Graphics.OpenGL.PixelFormat.Bgra, PixelType.UnsignedByte, data.Scan0); bitmap.UnlockBits(data); GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMinFilter, (int)TextureMinFilter.Linear); GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMagFilter, (int)TextureMagFilter.Linear); return id; } And here I call Sprite.Render() protected override void OnRenderFrame(FrameEventArgs e) { GL.ClearColor(Color.MidnightBlue); GL.Clear(ClearBufferMask.ColorBufferBit); _sprite.Render(); SwapBuffers(); base.OnRenderFrame(e); } As I stole this code from the Textures-Example from OpenTK, I don't understand why this doesn't work.

• Yet another (13)Permission denied error on Apache2 server

  I just can't figure it out. I'm running apache2 on a Ubuntu 10.04 i386 server. Whenever I visit my server (has an IP address, and is connected to internet with static IP xxx.xxx.xxx.xxx) so that's not the problem) in browser, mysub.domain.edu (renamed here), I get the following: Forbidden You don't have permission to access /index.html on this server The apache2 error log confirms this: [Mon Apr 18 02:38:20 2011] [error] [client zzz.zzz.zzz.zzz] (13)Permission denied: access to / denied I'll try to provide all necessary information below: 1) Contents of /etc/apache2/httpd.conf DirectoryIndex index.html index.php 2) Contents of /etc/apache2/sites-available/default <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /home/myusername/htdocs <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory "/home/myusername/htdocs/"> Options Indexes FollowSymLinks MultiViews AllowOverride None order allow,deny allow from all DirectoryIndex index.html index.php Satisfy any </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

• Why is this mod_rewrite RewriteRule directive not working in the .htaccess file?

  - by morgant

  I've got a site that was hosted on a linux el cheapo hosting service that I'm migrating to my Mac OS X 10.5 Leopard Server server running Apache 2.2.8 & PHP 5.2.5 w/rewrite_module enabled and AllowOverride All, but I'm running into an issue with the following lines in the .htaccess file: RewriteEngine On #RewriteRule ^view/([^/\.]+)/?$ /view.php?item=$1 [L] #RewriteRule ^order/([^/\.]+)/?$ /order.php?item=$1 [L] RewriteRule ^category/([^/\.]+)/?$ /category.php?category=$1 [L] As you can see, I've commented out the RewriteRule directives for /view/ and /order/, so I'm only dealing with /category/. When I attempt to load http://domain.tld/category/2/ it runs category.php (I've added debug code to confirm), but $_SERVER['REQUEST_URI'] comes through as /category/2/ and $_GET['category'] comes through as empty. I'm usually fine with troubleshooting .htaccess files and mod_rewrite directives, but this one's got me stumped for some reason. Update: I followed Josh's suggestion and here's the what's dumped to mod_rewrite.log when I try to access http://domain.tld/category/2/: 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (2) init rewrite engine with requested uri /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) applying pattern '.*' to uri '/category/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) pass through /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (2) init rewrite engine with requested uri /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) applying pattern '.*' to uri '/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) pass through /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/13 -> 13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri '13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/13

• /etc/rc.local not being run on Ubuntu Desktop Install

  I have been trying to get sphinx to run at boot, so I added some lines to /etc/rc.local but nothing happens when I start up. If i run it manually it works however. /etc/init.d/rc.local start works fine as does /etc/rc.local It's listed in the default runlevel and is all executable but it does not work.

• Can't send mail from Windows Phone (Postfix server)

  - by Dominic Williams

  Some background: I have a Dovecot/Postfix setup to handle email for a few domains. We have imap and smtp setup on various devices (Macs, iPhones, PCs, etc) and it works no problem. I've recently bought a Windows Phone and I'm trying to setup the mail account on there. I've got the imap part working great but for some reason it won't send mail. mail.log with debug_peer_list I've put this on pastebin because its quite long: http://pastebin.com/KdvMDxTL dovecot.log with verbose_ssl Apr 14 22:43:50 imap-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read client hello A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write server hello A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write certificate A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write server done A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 flush data [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read client key exchange A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read finished A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write change cipher spec A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write finished A [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 flush data [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x20, ret=1: SSL negotiation finished successfully [109.151.23.129] Apr 14 22:43:50 imap-login: Warning: SSL: where=0x2002, ret=1: SSL negotiation finished successfully [109.151.23.129] Apr 14 22:43:51 imap-login: Info: Login: user=<pixelfolio>, method=PLAIN, rip=109.151.23.129, lip=94.23.254.175, mpid=24390, TLS Apr 14 22:43:53 imap(pixelfolio): Info: Disconnected: Logged out bytes=9/331 Apr 14 22:43:53 imap-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [109.151.23.129] postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes config_directory = /etc/postfix debug_peer_list = 109.151.23.129 inet_interfaces = all mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 message_size_limit = 50240000 milter_default_action = accept milter_protocol = 2 mydestination = ks383809.kimsufi.com, localhost.kimsufi.com, localhost myhostname = ks383809.kimsufi.com mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname non_smtpd_milters = inet:127.0.0.1:8891,inet:localhost:8892 readme_directory = no recipient_delimiter = + smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_milters = inet:127.0.0.1:8891,inet:localhost:8892 smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes virtual_alias_domains = domz.co.uk ruck.in vjgary.co.uk scriptees.co.uk pixelfolio.co.uk filmtees.co.uk nbsbar.co.uk virtual_alias_maps = hash:/etc/postfix/alias_maps doveconf -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38.2-grsec-xxxx-grs-ipv6-64 x86_64 Ubuntu 11.10 auth_mechanisms = plain login log_path = /var/log/dovecot.log mail_location = mbox:~/mail/:INBOX=/var/mail/%u passdb { driver = pam } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } verbose_ssl = yes Any suggestions or help greatly appreciated.

• Why do two patterns (/.*) and (.*) match different strings? @per-directory (.htaccess) mod_rewrite RewriteRule

  - by Leftium

  Shouldn't the two patterns (/.*) and (.*) match the same string? My real question is actually: where did the "abc" go? Something funky seems to be happening inside the mod_rewrite engine... Given this .htaccess file in www/dir/: Options +FollowSymlinks RewriteEngine on RewriteRule (/.*) print_url_args.php?result=$1 A request for http://localhost/dir/abc/123/ results in: result ($1) = "/123/" $_REQUEST_URI = "/dir/abc/123/" If the / is removed from the pattern like RewriteRule (.*) print_url_args.php?result=$1 The same request for http://localhost/dir/abc/123/ results in: result ($1) = "print_url_args.php" $_REQUEST_URI = "/dir/abc/123/" update: posted rewrite log. 127.0.0.1 -

• Monit won't run

  - by Yaniro

  I have two identical EC2 instances (the second is a replica of the first), running Gentoo.

• Why is this mod_rewrite RewriteRule directive not working in the .htaccess file?

  - by morgant

  I've got a site that was hosted on a linux el cheapo hosting service that I'm migrating to my Mac OS X 10.5 Leopard Server server running Apache 2.2.8 & PHP 5.2.5 w/rewrite_module enabled and AllowOverride All, but I'm running into an issue with the following lines in the .htaccess file: RewriteEngine On #RewriteRule ^view/([^/\.]+)/?$ /view.php?item=$1 [L] #RewriteRule ^order/([^/\.]+)/?$ /order.php?item=$1 [L] RewriteRule ^category/([^/\.]+)/?$ /category.php?category=$1 [L] As you can see, I've commented out the RewriteRule directives for /view/ and /order/, so I'm only dealing with /category/. When I attempt to load http://domain.tld/category/2/ it runs category.php (I've added debug code to confirm), but $_SERVER['REQUEST_URI'] comes through as /category/2/ and $_GET['category'] comes through as empty. I'm usually fine with troubleshooting .htaccess files and mod_rewrite directives, but this one's got me stumped for some reason. Update: I followed Josh's suggestion and here's the what's dumped to mod_rewrite.log when I try to access http://domain.tld/category/2/: 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (2) init rewrite engine with requested uri /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) applying pattern '.*' to uri '/category/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) pass through /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (2) init rewrite engine with requested uri /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) applying pattern '.*' to uri '/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) pass through /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/13 -> 13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri '13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/13

• Can't launch glassfish on ec2 - can't open port

  - by orange80

  I'm trying to start glassfish on an EBS-based AMI of Ubuntu 10.04 64-bit. I have used glassfish on non-ec2 servers with no problems, but on ec2 I get this message: $ sudo -u glassfish bin/asadmin start-domain domain1 There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server. Command start-domain failed. I know that ec2 has requires that firewall rules be modified using ec2-authorize to let outside traffic thru the firewall, as I had to do to make ssh work. This still doesn't explain the port error when all I'm trying to do is start glassfish so I can try $ wget localhost:8080and make sure it's working. This is very frustrating and I'd really appreciate any help. Thanks. FINAL UPDATE: Sorry if you came here looking for answers. I never figured out what was causing the problem. I created another fresh instance, installed the same stuff, and Glassfish worked perfectly. Something obviously got boned during installation, but I have no idea what. I guess it will remain a mystery. UPDATE: Here's what I get from netstat: # netstat -nuptl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 462/sshd tcp6 0 0 :::22 :::* LISTEN 462/sshd udp 0 0 0.0.0.0:5353 0.0.0.0:* 483/avahi-daemon: r udp 0 0 0.0.0.0:1194 0.0.0.0:* 589/openvpn udp 0 0 0.0.0.0:37940 0.0.0.0:* 483/avahi-daemon: r udp 0 0 0.0.0.0:68 0.0.0.0:* 377/dhclient3 UPDATE: One more thing... I know that the "net.ipv6.bindv6only" kernel option can cause problems with java networking, so I did set this: # sysctl -w net.ipv6.bindv6only=0 UPDATE: I also verified that it has nothing at all to do with the port number (4848). As you can see here, when I changed the admin-listener port in domain.xml to 4949, I get a similar message: # sudo -u glassfish bin/asadmin start-domain domain1 There is a process already using the admin port 4949 -- it probably is another instance of a GlassFish server. Command start-domain failed. UPDATE: Here are the contents of /etc/hosts: 127.0.0.1 localhost # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts I should mention that I have another Ubuntu Lucid 10.04 64-bit slice that is NOT hosted on ec2, and set it up the exact same way with no problems whatsoever. Also server.log doesn't offer much insight either: # cat ./server.log Nov 20, 2010 8:46:49 AM com.sun.enterprise.admin.launcher.GFLauncherLogger info INFO: JVM invocation command line: /usr/lib/jvm/java-6-sun-1.6.0.22/bin/java -cp /opt/glassfishv3/glassfish/modules/glassfish.jar -XX:+UnlockDiagnosticVMOptions -XX:MaxPermSize=192m -XX:NewRatio=2 -XX:+LogVMOutput -XX:LogFile=/opt/glassfishv3/glassfish/domains/domain1/logs/jvm.log -Xmx512m -client -javaagent:/opt/glassfishv3/glassfish/lib/monitor/btrace-agent.jar=unsafe=true,noServer=true -Dosgi.shell.telnet.maxconn=1 -Djdbc.drivers=org.apache.derby.jdbc.ClientDriver -Dfelix.fileinstall.dir=/opt/glassfishv3/glassfish/modules/autostart/ -Djavax.net.ssl.keyStore=/opt/glassfishv3/glassfish/domains/domain1/config/keystore.jks -Dosgi.shell.telnet.port=6666 -Djava.security.policy=/opt/glassfishv3/glassfish/domains/domain1/config/server.policy -Dfelix.fileinstall.poll=5000 -Dcom.sun.aas.instanceRoot=/opt/glassfishv3/glassfish/domains/domain1 -Dcom.sun.enterprise.config.config_environment_factory_class=com.sun.enterprise.config.serverbeans.AppserverConfigEnvironmentFactory -Dosgi.shell.telnet.ip=127.0.0.1 -Djava.endorsed.dirs=/opt/glassfishv3/glassfish/modules/endorsed:/opt/glassfishv3/glassfish/lib/endorsed -Dcom.sun.aas.installRoot=/opt/glassfishv3/glassfish -Djava.ext.dirs=/usr/lib/jvm/java-6-sun-1.6.0.22/lib/ext:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/ext:/opt/glassfishv3/glassfish/domains/domain1/lib/ext -Dfelix.fileinstall.bundles.new.start=true -Djavax.net.ssl.trustStore=/opt/glassfishv3/glassfish/domains/domain1/config/cacerts.jks -Dcom.sun.enterprise.security.httpsOutboundKeyAlias=s1as -Djava.security.auth.login.config=/opt/glassfishv3/glassfish/domains/domain1/config/login.conf -DANTLR_USE_DIRECT_CLASS_LOADING=true -Dfelix.fileinstall.debug=1 -Dorg.glassfish.web.rfc2109_cookie_names_enforced=false -Djava.library.path=/opt/glassfishv3/glassfish/lib:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/amd64/server:/usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/amd64:/usr/lib/jvm/java-6-sun-1.6.0.22/lib/amd64:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib com.sun.enterprise.glassfish.bootstrap.ASMain -domainname domain1 -asadmin-args start-domain,,,domain1 -instancename server -verbose false -debug false -asadmin-classpath /opt/glassfishv3/glassfish/modules/admin-cli.jar -asadmin-classname com.sun.enterprise.admin.cli.AsadminMain -upgrade false -domaindir /opt/glassfishv3/glassfish/domains/domain1 -read-stdin true

• High Load mysql on Debian server

  - by Oleg Abrazhaev

  I have Debian server with 32 gb memory. And there is apache2, memcached and nginx on this server. Memory load always on maximum. Only 500m free. Most memory leak do MySql. Apache only 70 clients configured, other services small memory usage. When mysql use all memory it stops. And nothing works, need mysql reboot. Mysql configured use maximum 24 gb memory. I have hight weight InnoDB bases. (400000 rows, 30 gb). And on server multithread daemon, that makes many inserts in this tables, thats why InnoDB. There is my mysql config.

• Deploying play! 2.0 application on an apache server with a reverse proxy

  - by locrizak

  I'm trying to deploy my play! 2.0 application on an Ubuntu 11.10 server and I have been running into error after error and hope someone can help me here. I am try to deploy my Play! application using a reverse proxy on Apache 2. I have enabled the apache proxy modules and configured the proxy.conf file in mods_enabled. The vhost for my domain looks like this: <Directory /var/www/stage.domain.com AllowOverride None Order Deny,Allow Deny from all </Directory <VirtualHost *:80 DocumentRoot /var/www/stage.domain.com/web ServerName stage.domain.com ServerAdmin [email protected] # ProxyRequests Off # ProxyPreserveHost On <Proxy * Order allow,deny Allow from all </Proxy # ProxyVia On # ProxyPass /play/ http://localhost:9000/ # ProxyPassReverse /play/ http://localhost:9000/ ErrorLog /var/log/ispconfig/httpd/stage.domain.com/error.log ErrorDocument 400 /error/400.html ErrorDocument 401 /error/401.html ErrorDocument 403 /error/403.html ErrorDocument 404 /error/404.html ErrorDocument 405 /error/405.html ErrorDocument 500 /error/500.html ErrorDocument 502 /error/502.html ErrorDocument 503 /error/503.html <IfModule mod_ssl.c </IfModule <Directory /var/www/stage.domain.com/web Options FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory <Directory /var/www/clients/client2/web7/web Options FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory # Clear PHP settings of this website <FilesMatch "\.ph(p3?|tml)$" SetHandler None </FilesMatch # mod_php enabled AddType application/x-httpd-php .php .php3 .php4 .php5 php_admin_value sendmail_path "/usr/sbin/sendmail -t -i [email protected]" php_admin_value upload_tmp_dir /var/www/clients/client2/web7/tmp php_admin_value session.save_path /var/www/clients/client2/web7/tmp # PHPIniDir /var/www/conf/web7 php_admin_value open_basedir /var/www/clients/client2/web7/:/var/www/clients/client2/web7/web:/va$ # add support for apache mpm_itk <IfModule mpm_itk_module AssignUserId web7 client2 </IfModule <IfModule mod_dav_fs.c # Do not execute PHP files in webdav directory <Directory /var/www/clients/client2/web7/webdav <FilesMatch "\.ph(p3?|tml)$" SetHandler None </FilesMatch </Directory # DO NOT REMOVE THE COMMENTS! # IF YOU REMOVE THEM, WEBDAV WILL NOT WORK ANYMORE! # WEBDAV BEGIN # WEBDAV END </IfModule # <Location /play/ # ProxyPass http://localhost:9000/ # SetEnv force-proxy-request-1.0 1 # SetEnv proxy-nokeepalive 1 # </Location ProxyRequests Off ProxyPass /play/ http://localhost:9000/ ProxyPassReverse /play/ localhost:9000/ ProxyPass /play http://localhost:9000/ ProxyPassReverse /play http://localhost:9000/ # SetEnv force-proxy-request-1.0 1 # SetEnv proxy-nokeepalive 1 </VirtualHost This vhost file was generated by ispconfig and I have not touched anything that was there before just added onto. As you can see by the commented out parts I have tried a lot of different things based on random tutorials I have found but all of them have ended up in Internal Server Error, 503 and most often a '502 Bad Gateway`. I can start play and it does connect successfully to my database. I can get a page to show up when there is an error and the play! stack trace error pages comes up but where everything is fine I get one of the errors above. My application.conf file looks like this: db info ....... application.mode=PROD logger.root=ERROR # Logger used by the framework: logger.play=INFO # Logger provided to your application: logger.application=DEBUG http.path="/play/" XForwardedSupport="127.0.0.1" And my hosts file looks like this (I have never changed or added anything to the host file): 127.0.0.1 localhost 127.0.1.1 matrix # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters Any insights onto what I might be doing wrong or if theres anything I can try please let me know! Thanks!! Edit Again the reverse proxy will work (I checked with sending to to google.com). Its when there is a successful connection to Netty. It's like Netty refuses the connection to the page. Edit 2 output from apachectl -S _default_:8081 127.0.0.1 (/etc/apache2/sites-enabled/000-apps.vhost:10) *:8090 is a NameVirtualHost default server 127.0.0.1 (/etc/apache2/sites-enabled/000-ispconfig.vhost:10) port 8090 namevhost 127.0.0.1 (/etc/apache2/sites-enabled/000-ispconfig.vhost:10) *:80 is a NameVirtualHost default server 127.0.0.1 (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost 127.0.0.1 (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost stage.domain.com (/etc/apache2/sites-enabled/100-stage.domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7)
