  • How to retrieve path for a file embedded in Resources (Resource Manager)

    - by curiousone
    I am trying to retrieve file path for a html file that is embedded in resource (resx file) in VS2008 C# project. I want to give path of this file to native webbrowser control (PIEHtml) to be able to navigate (DTM_NAVIGATE) in my application. I know I can pass the string to this control using DTM_ADDTEXTW but since html text size is so big, I dont want to pass string to the control. I need to somehow extract the file path for this html file embedded inside resource manager. I tried using but this does not give the file path of html inside assembly: private ResourceManager resManager = new ResourceManager("AppName.FolderName.FileName", System.Reflection.Assembly.GetExecutingAssembly()); this.lbl.Text = resManager.GetString("StringInResources"); and also read Retrieving Resources in Satellite Assemblies but it did not solve my problem. Can somebody please provide info as to how to achieve this ?

  • Creating dynamic resource in cookbook

    - by zsong
    Long story short, here is my code: template "...." do .... notifies :restart,"service[myservice_One]" notifies :restart,"service[myservice_Two]" end ['One', 'Two'].each do |proj| service 'myservice_#{proj}' do start_command "setsid /etc/init.d/my_command #{proj} start" stop_command "setsid /etc/init.d/my_command #{proj} stop" restart_command "setsid /etc/init.d/my_command #{proj} restart" status_command "setsid /etc/init.d/my_command #{proj} status" supports :status => true, :restart => true action [:enable,:start] end end I got this error: template[...] is configured to notify resource service[celery_worker_One] with action restart, but service[celery_worker_One] cannot be found in the resource collection. I know I can duplicate my code to make it work but how to dynamically create the services? Thanks!

  • How to load a resource bundle from a file resource in Java?

    - by user143794
    I have a file called mybundle.txt in c:/temp - c:/temp/mybundle.txt how do I load this file into a java.util.resource bundle? The file is a valid resource bundle. This does not seem to work: java.net.URL resourceURL = null; String path = "c:/temp/mybundle.txt"; java.io.File fl = new java.io.File(path); try { resourceURL = fl.toURI().toURL(); } catch (MalformedURLException e) { } URLClassLoader urlLoader = new URLClassLoader(new java.net.URL[]{resourceURL}); java.util.ResourceBundle bundle = java.util.ResourceBundle.getBundle( path , java.util.Locale.getDefault(), urlLoader ); What is the best way to do this?

  • Dynamic reference to resource files in C#

    - by Joda
    I have an application on which I am implementing localization. I now need to dynamically reference a name in the resouce file. assume I have a resource file called Login.resx, an a number of strings: foo="hello", bar="cruel" and baz="world" normally, I will refer as: String result =Login.foo; and result=="hello"; my problem is, that at code time, I do not know if I want to refer to foo, bar or baz - I have a string that contains either "foo", "bar" or "baz". I need something like: Login["foo"]; Does anyone know if there is any way to dynamically reference a string in a resource file?

  • Aptana Open Resource Key Binding

    - by yagudaev
    The default keyboard shortcut for open resource in Eclipse is Ctrl+Shift+R. It is also the case in Aptana, but there also seems to be a conflicting key since when clicked it brings up a context menu with 2 options "Run" and "Open Resource". How to I avoid having this context menu pop up? I tried to go to the preferences and look for conflicting key-bindings but I could not find it. I am also not sure what "Run" command is actually bound (I tried searching based on the key combination, that did not seem to have worked).

  • does heartbeat v3 support same resource agent types of pacemaker?

    - by Emre He
    As we know, Pacemaker supports three types of Resource Agents, ? LSB Resource Agents, ? OCF Resource Agents, ? legacy Heartbeat Resource Agents http://www.linux-ha.org/wiki/Resource_Agents does heartbeat v3 support above 3 types resource agent? or it only support LSB and legacy heartbeat resource agents? because we have only virtual ip and one service need to switch in ha cluster, so we decide not involve pacemaker, so we come to this question, for example we cannot monitor the application service by heartbeat, heartbeat only can handle to start it on active node. thanks, Emre

  • ControlTemplate Exception: "XamlParseException: Cannot find a Resource with the Name/Key"

    - by akaphenom
    If I move the application resources to a UserControl resources everythgin runs groovy. I still don't understand why. I noticed that my application object MyApp did more than inherit from Application it loaded an XAML for the main template and connected all the plumbing. So I decided to create a user control to remove the template from the applciation (thinking there may be an even order issue not allowing my resource to be found). namespace Module1 type Template() as this = //inherit UriUserControl("/FSSilverlightApp;component/template.xaml", "") inherit UriUserControl("/FSSilverlightApp;component/templateSimple.xaml", "") do Application.LoadComponent(this, base.uri) let siteTemplate : Grid = (this.Content :?> FrameworkElement) ? siteTemplate let nav : Frame = siteTemplate ? contentFrame let pages : UriUserControl array = [| new Module1.Page1() :> UriUserControl ; new Module1.Page2() :> UriUserControl ; new Module1.Page3() :> UriUserControl ; new Module1.Page4() :> UriUserControl ; new Module1.Page5() :> UriUserControl ; |] do nav.Navigate((pages.[0] :> INamedUriProvider).Uri) |> ignore type MyApp() as this = inherit Application() do Application.LoadComponent(this, new System.Uri("/FSSilverlightApp;component/App.xaml", System.UriKind.Relative)) do System.Windows.Browser.HtmlPage.Plugin.Focus() this.RootVisual <- new Template() ; // test code to check for the existance of the ControlTemplate - it exists let a = Application.Current.Resources.MergedDictionaries let b = a.[0] let c = b.Count let d : ControlTemplate = downcast c.["TransitioningFrame"] () "/FSSilverlightApp;component/templateSimple.xaml" <UserControl x:Class="Module1.Template" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Grid HorizontalAlignment="Center" Background="White" Name="siteTemplate"> <StackPanel Grid.Row="3" Grid.Column="2" Name="mainPanel"> <!--Template="{StaticResource TransitioningFrame}"--> <navigation:Frame Name="contentFrame" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Template="{StaticResource TransitioningFrame}"/> </StackPanel> </Grid> </UserControl> "/FSSilverlightApp;component/App.xaml" <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Module1.MyApp"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/FSSilverlightApp;component/TransitioningFrame.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> "/FSSilverlightApp;component/TransitioningFrame.xaml" <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ControlTemplate x:Key="TransitioningFrame" TargetType="navigation:Frame"> <Border Background="Olive" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="5" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}"/> </Border> </ControlTemplate> </ResourceDictionary> Unfortunately that did not work.

  • Clusterware 11gR2 &ndash; Setting up an Active/Passive failover configuration

    - by Gilles Haro
    Oracle is providing a large range of interesting solutions to ensure High Availability of the database. Dataguard, RAC or even both configurations (as recommended by Oracle for a Maximum Available Architecture - MAA) are the most frequently found and used solutions. But, when it comes to protecting a system with an Active/Passive architecture with failover capabilities, people often thinks to other expensive third party cluster systems. Oracle Clusterware technology, which comes along at no extra-cost with Oracle Database or Oracle Unbreakable Linux, is - in the knowing of most people - often linked to Oracle RAC and therefore, is seldom used to implement failover solutions. Oracle Clusterware 11gR2  (a part of Oracle 11gR2 Grid Infrastructure)  provides a comprehensive framework to setup automatic failover configurations. It is actually possible to make "failover-able'", and then to protect, almost any kind of application (from the simple xclock to the most complex Application Server). Quoting Oracle: “Oracle Clusterware is a portable cluster software that allows clustering of single servers so that they cooperate as a single system. Oracle Clusterware also provides the required infrastructure for Oracle Real Application Clusters (RAC). In addition Oracle Clusterware enables the protection of any Oracle application or any other kind of application within a cluster.” In the next couple of lines, I will try to present the different steps to achieve this goal : Have a fully operational 11gR2 database protected by automatic failover capabilities. I assume you are fluent in installing Oracle Database 11gR2, Oracle Grid Infrastructure 11gR2 on a Linux system and that ASM is not a problem for you (as I am using it as a shared storage). If not, please have a look at Oracle Documentation. As often, I made my tests using an Oracle VirtualBox environment. The scripts are tested and functional on my system. Unfortunately, there can always be a typo or a mistake. This blog entry does not replace a course around the Clusterware Framework. I just hope it will let you see how powerful it is and that it will give you the whilst to go further with it...  Note : This entry has been revised (rev.2) following comments from Philip Newlan. Prerequisite 2 Linux boxes (OELCluster01 and OELCluster02) at the same OS level. I used OEL 5 Update 5 with an Enterprise Kernel. Shared Storage (SAN). On my VirtualBox system, I used Openfiler to simulate the SAN Oracle 11gR2 Database (11.2.0.1) Oracle 11gR2 Grid Infrastructure (11.2.0.1)   Step 1 - Install the software Using asmlib, create 3 ASM disks (ASM_CRS, ASM_DTA and ASM_FRA) Install Grid Infrastructure for a cluster (OELCluster01 and OELCluster02 are the 2 nodes of the cluster) Use ASM_CRS to store Voting Disk and OCR. Use SCAN. Install Oracle Database Standalone binaries on both nodes. Use asmca to check/mount the disk groups on 2 nodes Use dbca to create and configure a database on the primary node Let's name it DB11G. Copy the pfile, password file to the second node. Create adump directoty on the second node.   Step 2 - Setup the resource to be protected After its creation with dbca, the database is automatically protected by the Oracle Restart technology available with Grid Infrastructure. Consequently, it restarts automatically (if possible) after a crash (ex: kill -9 smon). A database resource has been created for that in the Cluster Registry. We can observe this with the command : crsctl status resource that shows and ora.dba11g.db entry. Let's save the definition of this resource, for future use : mkdir -p /crs/11.2.0/HA_scripts chown oracle:oinstall /crs/11.2.0/HA_scripts crsctl status resource ora.db11g.db -p > /crs/11.2.0/HA_scripts/myResource.txt Although very interesting, Oracle Restart is not cluster aware and cannot restart the database on any other node of the cluster. So, let's remove it from the OCR definitions, we don't need it ! srvctl stop database -d DB11G srvctl remove database -d DB11G Instead of it, we need to create a new resource of a more general type : cluster_resource. Here are the steps to achieve this : Create an action script :  /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh #!/bin/bash export ORACLE_HOME=/oracle/product/11.2.0/dbhome_1 export ORACLE_SID=DB11G case $1 in 'start')   $ORACLE_HOME/bin/sqlplus /nolog <<EOF   connect / as sysdba   startup EOF   RET=0   ;; 'stop')   $ORACLE_HOME/bin/sqlplus /nolog <<EOF   connect / as sysdba   shutdown immediate EOF   RET=0   ;; 'clean')   $ORACLE_HOME/bin/sqlplus /nolog <<EOF   connect / as sysdba   shutdown abort    ##for i in `ps -ef | grep -i $ORACLE_SID | awk '{print $2}' ` ;do kill -9 $i; done EOF   RET=0   ;; 'check')    ok=`ps -ef | grep smon | grep $ORACLE_SID | wc -l`    if [ $ok = 0 ]; then      RET=1    else      RET=0    fi    ;; '*')      RET=0   ;; esac if [ $RET -eq 0 ]; then    exit 0 else    exit 1 fi   This script must provide, at least, methods to start, stop, clean and check the database. It is self-explaining and contains nothing special. Just be aware that it must be runnable (+x), it runs as Oracle user (because of the ACL property - see later) and needs to know about the environment. Also make sure it exists on every node of the cluster. Moreover, as of 11.2, the clean method is mandatory. It must provide the “last gasp clean up”, for example, a shutdown abort or a kill –9 of all the remaining processes. chmod +x /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh scp  /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh   oracle@OELCluster02:/crs/11.2.0/HA_scripts Create a new resource file, based on the information we got from previous  myResource.txt . Name it myNewResource.txt. myResource.txt  is shown below. As we can see, it defines an ora.database.type resource, named ora.db11g.db. A lot of properties are related to this type of resource and do not need to be used for a cluster_resource.

Notice the HOSTING_MEMBERS that enumerates the members of the cluster (as returned by the olsnodes command).

Take care of the resource type. It needs to be a cluster_resource and not a ora.database.type resource (Oracle recommendation) .   crsctl add resource DB11G.db  -type cluster_resource -file /crs/11.2.0/HA_scripts/myNewResource.txt Step 3 - Start the resource crsctl start resource DB11G.db This command launches the ACTION_SCRIPT with a start and a check parameter on the primary node of the cluster. Step 4 - Test this We will test the setup using 2 methods. crsctl relocate resource DB11G.db This command calls the ACTION_SCRIPT  (on the two nodes)  to stop the database on the active node and start it on the other node. Once done, we can revert back to the original node, but, this time we can use a more "MS$ like" method :Turn off the server on which the database is running. After short delay, you should observe that the database is relocated on node 1. Conclusion Once the software installed and the standalone database created (which is a rather common and usual task), the steps to reach the objective are quite easy : Create an executable action script on every node of the cluster. Create a resource file. Create/Register the resource with OCR using the resource file. Start the resource. This solution is a very interesting alternative to licensable third party solutions.

Take care of the resource type. It needs to be a cluster_resource and not a ora.database.type resource (Oracle recommendation) .   crsctl add resource DB11G.db  -type cluster_resource -file /crs/11.2.0/HA_scripts/myNewResource.txt Step 3 - Start the resource crsctl start resource DB11G.db This command launches the ACTION_SCRIPT with a start and a check parameter on the primary node of the cluster. Step 4 - Test this We will test the setup using 2 methods. crsctl relocate resource DB11G.db This command calls the ACTION_SCRIPT  (on the two nodes)  to stop the database on the active node and start it on the other node. Once done, we can revert back to the original node, but, this time we can use a more “MS$ like” method :Turn off the server on which the database is running. After short delay, you should observe that the database is relocated on node 1. Conclusion Once the software installed and the standalone database created (which is a rather common and usual task), the steps to reach the objective are quite easy : Create an executable action script on every node of the cluster. Create a resource file. Create/Register the resource with OCR using the resource file. Start the resource. This solution is a very interesting alternative to licensable third party solutions.   References Clusterware 11gR2 documentation Oracle Clusterware Resource Reference   Gilles Haro Technical Expert - Core Technology, Oracle Consulting

  • Using "offline files sync" to sync with a local resource [closed]

    - by Kije
    Possible Duplicate: Which is the best application to Sync two folders? I have been trying get my machine (XP-Pro SP3) to sync files to a local USB drive in the same way as I can with mapped network drives. I particularly want to the sync to happen automatically when the USB is connected - in the same way that Off-line files will sync when the network drive comes on line. I can get a folder on the USB mounted as a network drive, but cannot get XP to offer the off-line files functionality. I have tried MS's SyncToy - it works as advertised, and will do scheduled and ad-hoc sync's, but does not seem to offer automatic syncs. I suspect I could do this by plugging my USB into another machine on my network - but that seems heavy handed. All insight appreciated - If you know this cannot be done please say so.

  • AWStats consumes too much resource, how to disable temporarily

    - by trante
    For some days AWStats takes %10-%20 of my CPU, takes 400-550 MB RAM and works for hours. Maybe my site's traffic became larger so process time takes more time than before or some bugs in program makes this. Anyway I want to disable AWStats temporarily. Maybe I would want to activate it in future. I found that answer. But it gives commands to remove AWStats. I only want to disable it temporarily. My system is Centos 6.3, Plesk 11.5.30 Update #19. I tried to disable cron jobs. I run this # killall awstats.pl I opened # vi /etc/cron.daily/awstats file and I changed it to this: #!/bin/sh #/usr/share/awstats/awstats_updateall.pl now -awstatsprog=/var/www/cgi-bin/awstats/awstats.pl -configdir=/etc/awstats >/dev/null 2>&1 exit 0 After some time I still see that awstats is running. What should I do more to not to awstats run again ? But without removing my files. After changing " /etc/cron.daily/awstats" file awstats doesn't start in daytime. But every night in 03:15 awstats starts again. Because of Plesk auto updates are working at that time, I changed from Plesk. Don't auto update automatically. But it seems like last night at 03:15 awstats started again. Is there any way to stop awstats temporarily except this solution ? Because this solution deletes awstats configs permanently and I don't know how to revert it back in future ? Turn off all AWStats for Plesk 11+ domains #!/bin/bash for i in /var/www/vhosts/*; do echo "Turning off and deleting Stats for" echo `basename $i` /usr/local/psa/admin/bin/webstatmng --unset-configs --stat-prog=awstats --domain-name=`basename $i` /usr/local/psa/admin/bin/webstatmng --clean --stat-prog=awstats --domain-name=`basename $i` done

  • How do I run a non-service program as a service on Windows 2008 Server?

    - by Lasse V. Karlsen
    I found this page that tells me how to set up Windows Live Sync as a background service on Windows 2003 Server, unfortunately the resource kit tools for 2003 that are mentioned does not work on 2008 server. http://mswhs.freeforums.org/windows-live-sync-as-a-service-on-whs-t623.html Also, apparently there is no resource kit tools downloadable for Windows 2008 Server that I can find. Perhaps someone has a link to the relevant tools? (INSTSRV.EXE and SRVANY.EXE.) Using just plain SC.EXE doesn't work as I assume that the program is then required to be a normal service, and not just any executable. What other options do I have? Can I use the task scheduler on 2008 server to start the WindowsLiveSync executable, will that work? I need the executable to stay running even after I've logged off from the server.

  • ASPX throws "404 The resource cannot be found"

    - by Diegoeche
    I'm deploying a website under a virtual directory using IIS. For some strange reason, Default.html works, but Default.aspx throws a 404. I have tried these: There's another virtual directory that contains an older version of the application and that one just works. I checked the properties of each virtual directory and they looked the same. I checked that the root didn't had any extra backslashes

  • Troubleshooting source of heavy resource-usage on a windows server 2008 running multiple sites

    - by batman_man
    Hi, I am running about 10 asp.net websites on a hosted virtual server. The server runs Server 2008 - each website is backed by its own database running on SQL server 2008 on the same box. Lately the box has seemed really slow. The only kind of discovery i could think of doing was looking in the task manager, where i can see w3wp and sqlserver.exe jumping to 40% cpu usage every 5-10 seconds. What are the steps i can take to determine which of my websites is taking these resources and or what database is getting hit the most? I have of course ssms installed on the machine as well. As you can tell, my sysadmin skills are very very limited - any help would be much appreciated.

  • DBRD dual primary Heartbeat resource management

    - by Jon Skarpeteig
    I have the following setup: Two servers with DRBD running dual primary with OCFS2 Heartbeat with two virtual ips, one for each server Round robin DNS to load balance NFS across the two vIPs Shutting down Server1 for a period of time, cause Server2 to take over the vIP for failover. However, when Server1 returns - it takes over the designated vIP as soon as heartbeat gets connection again - even though the DRBD is running sync (and thus not up to date) How can I configure heartbeat to perform failback as soon as Server1 again is in sync with Server2 ? (And not before)

  • Not Able To Connect to Shared Resource

    - by bobber205
    We are using an older version of BartPE and are not able to connect to shared folders on our subnet. It says the network name could not be found. Connecting to the shared folder on the machine that is hosting it works fine. Any ideas on what might cause this? Thanks! Edit1: Got wireshark running and monitored traffic from the offending machine and tried to map. ZERO packets from the other machine were seen. :(
