  • Getting all rows from a Table where the column contains only 0

    - by Auro
    I got a little problem i need a sql query that gives all rows back that only contains 0 in it. the column is defined as varchar2(6) the values in the column looks like this: 0 00 00 100 bc00 000000 00000 my first solution would be like this: Oracle: substr('000000' || COLUMN_NAME, -6) = '000000' SQL Server: right('000000' + COLUMN_NAME, 6) = '000000' is there an other way? (it needs to work on both systems)

  • SQL Command Not Properly Ended (Nested Aggregation with Group-by)

    - by snowind
    I keep getting this error when I tried to execute this query, although I couldn't figure out what went wrong. I'm using Oracle and JDBC. Here's the query: SELECT Temp.flight_number, Temp.avgprice FROM (SELECT P.flight_number, AVG (P.amount) AS avgprice FROM purchase P GROUP BY P.flight_number) AS Temp WHERE Temp.avgprice = (SELECT MAX (Temp.avgprice) FROM Temp) I'm trying to get the maximum of average price of the tickets that customers have booked, group by flight_number.

  • Coding With Windows Azure IaaS

    - by Hisham El-bereky
    This post will focus on some advanced programming topics concerned with IaaS (Infrastructure as a Service) which provided as windows azure virtual machine (with its related resources like virtual disk and virtual network), you know that windows azure started as PaaS cloud platform but regarding to some business cases which need to have full control over their virtual machine, so windows azure directed toward providing IaaS. Sometimes you will need to manage your cloud IaaS through code may be for these reasons: Working on hyper-cloud system by providing bursting connector to windows azure virtual machines Providing multi-tenant system which consume windows azure virtual machine Automated process on your on-premises or cloud service which need to utilize some virtual resources We are going to implement the following basic operation using C# code: List images Create virtual machine List virtual machines Restart virtual machine Delete virtual machine Before going to implement the above operations we need to prepare client side and windows azure subscription to communicate correctly by providing management certificate (x.509 v3 certificates) which permit client access to resources in your Windows Azure subscription, whilst requests made using the Windows Azure Service Management REST API require authentication against a certificate that you provide to Windows Azure More info about setting management certificate located here. And to install .cer on other client machine you will need the .pfx file, or if not exist by exporting .cer as .pfx Note: You will need to install .net 4.5 on your machine to try the code So let start This post built on the post sent by Michael Washam "Advanced Windows Azure IaaS – Demo Code", so I'm here to declare some points and to add new operation which is not exist in Michael's demo The basic C# class object used here as client to azure REST API for IaaS service is HttpClient (Provides a base class for sending HTTP requests and receiving HTTP responses from a resource identified by a URI) this object must be initialized with the required data like certificate, headers and content if required. Also I'd like to refer here that the code is based on using Asynchronous programming with calls to azure which enhance the performance and gives us the ability to work with complex calls which depends on more than one sub-call to achieve some operation The following code explain how to get certificate and initializing HttpClient object with required data like headers and content HttpClient GetHttpClient() { X509Store certificateStore = null; X509Certificate2 certificate = null; try { certificateStore = new X509Store(StoreName.My, StoreLocation.CurrentUser); certificateStore.Open(OpenFlags.ReadOnly); string thumbprint = ConfigurationManager.AppSettings["CertThumbprint"]; var certificates = certificateStore.Certificates.Find(X509FindType.FindByThumbprint, thumbprint, false); if (certificates.Count > 0) { certificate = certificates[0]; } } finally { if (certificateStore != null) certificateStore.Close(); }   WebRequestHandler handler = new WebRequestHandler(); if (certificate!= null) { handler.ClientCertificates.Add(certificate); HttpClient httpClient = new HttpClient(handler); //And to set required headers lik x-ms-version httpClient.DefaultRequestHeaders.Add("x-ms-version", "2012-03-01"); httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml")); return httpClient; } return null; }  Let us keep the object httpClient as reference object used to call windows azure REST API IaaS service. For each request operation we need to define: Request URI HTTP Method Headers Content body (1) List images The List OS Images operation retrieves a list of the OS images from the image repository Request URI https://management.core.windows.net/<subscription-id>/services/images] Replace <subscription-id> with your windows Id HTTP Method GET (HTTP 1.1) Headers x-ms-version: 2012-03-01 Body None.  C# Code List<String> imageList = new List<String>(); //replace _subscriptionid with your WA subscription String uri = String.Format("https://management.core.windows.net/{0}/services/images", _subscriptionid);  HttpClient http = GetHttpClient(); Stream responseStream = await http.GetStreamAsync(uri);  if (responseStream != null) {      XDocument xml = XDocument.Load(responseStream);      var images = xml.Root.Descendants(ns + "OSImage").Where(i => i.Element(ns + "OS").Value == "Windows");      foreach (var image in images)      {      string img = image.Element(ns + "Name").Value;      imageList.Add(img);      } } More information about the REST call (Request/Response) located here on this link http://msdn.microsoft.com/en-us/library/windowsazure/jj157191.aspx (2) Create Virtual Machine Creating virtual machine required service and deployment to be created first, so creating VM should be done through three steps incase hosted service and deployment is not created yet Create hosted service, a container for service deployments in Windows Azure. A subscription may have zero or more hosted services Create deployment, a service that is running on Windows Azure. A deployment may be running in either the staging or production deployment environment. It may be managed either by referencing its deployment ID, or by referencing the deployment environment in which it's running. Create virtual machine, the previous two steps info required here in this step I suggest here to use the same name for service, deployment and service to make it easy to manage virtual machines Note: A name for the hosted service that is unique within Windows Azure. This name is the DNS prefix name and can be used to access the hosted service. For example: http://ServiceName.cloudapp.net// 2.1 Create service Request URI https://management.core.windows.net/<subscription-id>/services/hostedservices HTTP Method POST (HTTP 1.1) Header x-ms-version: 2012-03-01 Content-Type: application/xml Body More details about request body (and other information) are located here http://msdn.microsoft.com/en-us/library/windowsazure/gg441304.aspx C# code The following method show how to create hosted service async public Task<String> NewAzureCloudService(String ServiceName, String Location, String AffinityGroup, String subscriptionid) { String requestID = String.Empty;

  • How should I define Pom.xml in each Module so that web module can communicate with the other two ejb modules?

    - by Kayser
    Maven, maven, maven. It must be very nice and it is nice by a small application. Now I want to build an ear project: with two EJB Modules, a web Module and ear module to build an ear file. Web Module is dependent on the other ejb modules.. How should I define Pom.xml in each Module so that web module can communicate with the other two ejb modules in ear and the ear module builds the right ear file? What I have done before: Module 1 -- Basic Module. All other modules are dependent to this Module. Basic functionality like login etc. <packaging>ejb</packaging> Module 1 -- Data Module.

  • JMX Based Monitoring - Part Four - Business App Server Monitoring

    - by Anthony Shorten
    In the last blog entry I talked about the Oracle Utilities Application Framework V4 feature for monitoring and managing aspects of the Web Application Server using JMX. In this blog entry I am going to discuss a similar new feature that allows JMX to be used for management and monitoring the Oracle Utilities business application server component. This feature is primarily focussed on performance tracking of the product. In first release of Oracle Utilities Customer Care And Billing (V1.x I am talking about), we used to use Oracle Tuxedo as part of the architecture. In Oracle Utilities Application Framework V2.0 and above, we removed Tuxedo from the architecture. One of the features that some customers used within Tuxedo was the performance tracking ability. The idea was that you enabled performance logging on the individual Tuxedo servers and then used a utility named txrpt to produce a performance report. This report would list every service called, the number of times it was called and the average response time. When I worked a performance consultant, I used this report to identify badly performing services and also gauge the overall performance characteristics of a site. When Tuxedo was removed from the architecture this information was also lost. While you can get some information from access.log and some Mbeans supplied by the Web Application Server it was not at the same granularity as txrpt or as useful. I am happy to say we have not only reintroduced this facility in Oracle Utilities Application Framework but it is now accessible via JMX and also we have added more detail into the performance tracking. Most of this new design was working with customers around the world to make sure we introduced a new feature that not only satisfied their performance tracking needs but allowed for finer grained performance analysis. As with the Web Application Server, the Business Application Server JMX monitoring is enabled by specifying a JMX port number in RMI Port number for JMX Business and initial credentials in the JMX Enablement System User ID and JMX Enablement System Password configuration options. These options are available using the configureEnv[.sh] -a utility. These credentials are shared across the Web Application Server and Business Application Server for authorization purposes. Once this is information is supplied a number of configuration files are built (by the initialSetup[.sh] utility) to configure the facility: spl.properties - contains the JMX URL, the security configuration and the mbeans that are enabled. For example, on my demonstration machine: spl.runtime.management.rmi.port=6750 spl.runtime.management.connector.url.default=service:jmx:rmi:///jndi/rmi://localhost:6750/oracle/ouaf/ejbAppConnector jmx.remote.x.password.file=scripts/ouaf.jmx.password.file jmx.remote.x.access.file=scripts/ouaf.jmx.access.file ouaf.jmx.com.splwg.ejb.service.management.PerformanceStatistics=enabled ouaf.jmx.* files - contain the userid and password. The default configuration uses the JMX default configuration. You can use additional security features by altering the spl.properties file manually or using a custom template. For more security options see JMX Security for more details. Once it has been configured and the changes reflected in the product using the initialSetup[.sh] utility the JMX facility can be used. For illustrative purposes I will use jconsole but any JSR160 complaint browser or client can be used (with the appropriate configuration). Once you start jconsole (ensure that splenviron[.sh] is executed prior to execution to set the environment variables or for remote connection, ensure java is in your path and jconsole.jar in your classpath) you specify the URL in the spl.runtime.management.connnector.url.default entry. For example: You are then able to track performance of the product using the PerformanceStatistics Mbean. The attributes of the PerformanceStatistics Mbean are counts of each object type. This is where this facility differs from txrpt. The information that is collected includes the following: The Service Type is captured so you can filter the results in terms of the type of service. For maintenance type services you can even see the transaction type (ADD, CHANGE etc) so you can see the performance of updates against read transactions. The Minimum and Maximum are also collected to give you an idea of the spread of performance. The last call is recorded. The date, time and user of the last call are recorded to give you an idea of the timeliness of the data. The Mbean maintains a set of counters per Service Type to give you a summary of the types of transactions being executed. This gives you an overall picture of the types of transactions and volumes at your site. There are a number of interesting operations that can also be performed: reset - This resets the statistics back to zero. This is an important operation. For example, txrpt is restricted to collecting statistics per hour, which is ok for most people. But what if you wanted to be more granular? This operation allows to set the collection period to anything you wish. The statistics collected will represent values since the last restart or last reset. completeExecutionDump - This is the operation that produces a CSV in memory to allow extraction of the data.

  • Web Self Service installation on Windows

    - by Rajesh Sharma
    Web Self Service (WSS) installation on windows is pretty straight forward but you might face some issues if deployed under tomcat. Here's a step-by-step guide to install Oracle Utilities Web Self Service on windows.   Below installation steps are done on: Oracle Utilities Framework version 2.2.0 Oracle Utilities Application - Customer Care & Billing version 2.2.0 Application server - Apache Tomcat 6.0.13 on default port 6500 Other settings include: SPLBASE = C:\spl\CCBDEMO22 SPLENVIRON = CCBV22 SPLWAS = TCAT   Follow these steps for a Web Self Service installation on windows: Download Web Self Service application from edelivery.   Copy the delivery file Release-SelfService-V2.2.0.zip from the Oracle Utilities Customer Care and Billing version 2.2.0 Web Self Service folder on the installation media to a directory on your Windows box where you would like to install the application, in our case it's a temporary folder C:\wss_temp.   Setup application environment, execute splenviron.cmd -e <ENVIRON_NAME>   Create base folder for Self Service application named SelfService under %SPLEBASE%\splapp\applications   Install Oracle Utilities Web Self Service   C:\wss_temp\Release-SelfService-V2.2.0>install.cmd -d %SPLEBASE%\splapp\applications\SelfService   Web Self Service installation menu. Populate environment values for each item.   ******************************************************** Pick your installation options: ******************************************************** 1. Destination directory name for installation.             | C:\spl\CCBDEMO22\splapp\applications\SelfService 2. Web Server Host.                                         | CCBV22 3. Web Server Port Number.                                  | 6500 4. Mail SMTP Host.                                          | CCBV22 5. Top Product Installation directory.                      | C:\spl\CCBDEMO22 6.     Web Application Server Type.                         | TCAT 7.     When OAS: SPLWeb OC4J instance name is required.     | OC4J1 8.     When WAS: SPLWeb server instance name is required.   | server1   P. Process the installation. Each item in the above list should be configured for a successful installation. Choose option to configure or (P) to process the installation:  P   Option 7 and Option 8 can be ignored for TCAT.   Above step installs SelfService.war file in the destination directory. We need to explode this war file. Change directory to the installation destination folder, and   C:\spl\CCBDEMO22\splapp\applications\SelfService>jar -xf SelfService.war   Review SelfServiceConfig.properties and CMSelfServiceConfig.properties. Change any properties value within the file specific to your installation/site. Generally default settings apply, for this exercise assumes that WEB user already exists in your application database.   For more information on property file customization, refer to Oracle Utilities Web Self Service Configuration section in Customer Care & Billing Installation Guide.   Add context entry in server.xml located under tomcat-base folder C:\spl\CCBDEMO22\product\tomcatBase\conf   ... <!-- SPL Context -->           <Context path="" docBase="C:/spl/CCBDEMO22/splapp/applications/root" debug="0" privileged="true"/>           <Context path="/appViewer" docBase="C:/spl/CCBDEMO22/splapp/applications/appViewer" debug="0" privileged="true"/>           <Context path="/help" docBase="C:/spl/CCBDEMO22/splapp/applications/help" debug="0" privileged="true"/>           <Context path="/XAIApp" docBase="C:/spl/CCBDEMO22/splapp/applications/XAIApp" debug="0" privileged="true"/>           <Context path="/SelfService" docBase="C:/spl/CCBDEMO22/splapp/applications/SelfService" debug="0" privileged="true"/> ...   Add User in tomcat-users.xml file located under tomcat-base folder C:\spl\CCBDEMO22\product\tomcatBase\conf   <user username="WEB" password="selfservice" roles="cisusers"/>   Note the password is "selfservice", this is the default password set within the SelfServiceConfig.properties file with base64 encoding.   Restart the application (spl.cmd stop | start)   12.  Although Apache Tomcat version 6.0.13 does not come with the admin pack, you can verify whether SelfService application is loaded and running, go to following URL http://server:port/manager/list, in our case it'll be http://ccbv22:6500/manager/list Following output will be displayed   OK - Listed applications for virtual host localhost /admin:running:0:C:/tomcat/apache-tomcat-6.0.13/webapps/ROOT/admin /XAIApp:running:0:C:/spl/CCBDEMO22/splapp/applications/XAIApp /host-manager:running:0:C:/tomcat/apache-tomcat-6.0.13/webapps/host-manager /SelfService:running:0:C:/spl/CCBDEMO22/splapp/applications/SelfService /appViewer:running:0:C:/spl/CCBDEMO22/splapp/applications/appViewer /manager:running:1:C:/tomcat/apache-tomcat-6.0.13/webapps/manager /help:running:0:C:/spl/CCBDEMO22/splapp/applications/help /:running:0:C:/spl/CCBDEMO22/splapp/applications/root   Also ensure that the XAIApp is running.   Run Oracle Utilities Web Self Service application http://server:port/SelfService in our case it'll be  http://ccbv22:6500/SelfService   Still doesn't work? And you get '503 HTTP response' at the time of customer registration?     This is because XAI service is still unavailable. There is initialize.waittime set for a default value of 90 seconds for the XAI Application to come up.   Remember WSS uses XAI to perform actions/validations on the CC&B database.

  • Finding nuggets in ARC discussions

    - by alanc
    A bit over twenty years ago, Sun formed an Architecture Review Committee (ARC) that evaluates proposals to change interfaces between components in Sun software products. During the OpenSolaris days, we opened many of these discussions to the community. While they’re back behind closed doors, and at a different company now, we still continue to hold these reviews for the software from what’s now the Sun Systems Group division of Oracle. Recently one of these reviews was held (via e-mail discussion) to review a proposal to update our GNU findutils package to the latest upstream release. One of the upstream changes discussed was the addition of an “oldfind” program. In findutils 4.3, find was modified to use the fts() function to walk the directory tree, and oldfind was created to provide the old mechanism in case there were bugs in the new implementation that users needed to workaround. In Solaris 11 though, we still ship the find descended from SVR4 as /usr/bin/find and the GNU find is available as either /usr/bin/gfind or /usr/gnu/bin/find. This raised the discussion of if we should add oldfind, and if so what should we call it. Normally our policy is to only add the g* names for GNU commands that conflict with an existing Solaris command – for instance, we ship /usr/bin/emacs, not /usr/bin/gemacs. In this case however, that seemed like it would be more confusing to have /usr/bin/oldfind be the older version of /usr/bin/gfind not of /usr/bin/find. Thus if we shipped it, it would make more sense to call it /usr/bin/goldfind, which several ARC members noted read more naturally as “gold find” than as “g old find”. One of the concerns we often discuss in ARC is if a change is likely to be understood by users or if it will result in more calls to support. As we hit this part of the discussion on a Friday at the end of a long week, I couldn’t resist putting forth a hypothetical support call for this command: “Hello, Oracle Solaris Support, how may I help you?” “My admin is out sick, but he sent an email that he put the findutils package on our server, and I can run goldfind now. I tried it, but goldfind didn’t find gold.” “Did he get the binutils package too?” “No he just said findutils, do we need binutils?” “Well, gold comes in the binutils package, so goldfind would be able to find gold if you got that package.” “How much does Oracle charge for that package?” “It’s free for Solaris users.” “You mean Oracle ships packages of gold to customers for free?” “Yes, if you get the binutils package, it includes GNU gold.” “New gold? Is that some sort of alchemy, turning stuff into gold?” “Not new gold, gold from the GNU project.” “Oracle’s taking gold from the GNU project and shipping it to me?” “Yes, if you get binutils, that package includes gold along with the other tools from the GNU project.” “And GNU doesn’t mind Oracle taking their gold and giving it to customers?” “No, GNU is a non-profit whose goal is to share their software.” “Sharing software sure, but gold? Where does a non-profit like GNU get gold anyway?” “Oh, Google donated it to them.” “Ah! So Oracle will give me the gold that GNU got from Google!” “Yes, if you get the package from us.” “How do I get the package with the gold?” “Just run pkg install binutils and it will put it on your disk.” “We’ve got multiple disks here - which one will it put it on?” “The one with the system image - do you know which one that is? “Well the note from the admin says the system is on the first disk and the users are on the second disk.” “Okay, so it should go on the first disk then.” “And where will I find the gold?” “It will be in the /usr/bin directory.” “In the user’s bin? So thats on the second disk?” “No, it would be on the system disk, with the other development tools, like make, as, and what.” “So what’s on the first disk?” “Well if the system image is there the commands should all be there.” “All the commands? Not just what?” “Right, all the commands that come with the OS, like the shell, ps, and who.” “So who’s on the first disk too?” “Yes. Did your admin say when he’d be back?” “No, just that he had a massive headache and was going home after I tried to get him to explain this stuff to me.” “I can’t imagine why.” “Oh, is why a command too?” “No, _why was a Ruby programmer.” “Ruby? Do you give those away with the gold too?” “Yes, but it comes in the ruby package, not binutils.” “Oh, I’ll have to have my admin get that package too! Thanks!” Needless to say, we decided this might not be the best idea. Since the GNU package hasn’t had to release a serious bug fix in the new find in the past few years, the new GNU find seems pretty stable, and we always have the SVR4 find to use as a fallback in Solaris, so it didn’t seem that adding oldfind was really necessary, so we passed on including it when we update to the new findutils release. [Apologies to Abbott, Costello, their fans, and everyone who read this far. The Gold (linker) page on Wikipedia may explain some of the above, but can’t explain why goldfind is the old GNU find, but gold is the new GNU ld.]

  • WCF: WSDL-first approach: Problems with generating fault types

    - by Juri
    Hi, I'm currently in the process of creating a WCF webservice which should be compatible with WS-I Basic Profile 1.1. I'm using a wsdl-first approach (actually for the first time), defining first the xsd for the complex types, the WSDL and then using svcutil.exe for generating the according server as well as client-side interfaces/proxies. So far everything works fine. Then I decided to add a fault to my WSDL. Regenerating with svcutil succeeded, but then I noticed that my generated fault doesn't have the properties I defined in my xsd file (which is imported by my WSDL). Fault XSD definition <?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://product.mycompany.com/groupsfault_v1.xsd" xmlns:tns="http://product.mycompany.com/groupsfault_v1.xsd"> <complexType name="groupsFault"> <sequence> <element name="code" type="int"/> <element name="message" type="string"/> </sequence> </complexType> </schema> Generated .Net fault object [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Xml.Serialization.XmlSchemaProviderAttribute("ExportSchema")] [System.Xml.Serialization.XmlRootAttribute(IsNullable=false)] public partial class groupFault : object, System.Xml.Serialization.IXmlSerializable { private System.Xml.XmlNode[] nodesField; private static System.Xml.XmlQualifiedName typeName = new System.Xml.XmlQualifiedName("groupFault", "http://sicp.services.siag.it/groups_v1.wsdl"); public System.Xml.XmlNode[] Nodes { get { return this.nodesField; } set { this.nodesField = value; } } public void ReadXml(System.Xml.XmlReader reader) { this.nodesField = System.Runtime.Serialization.XmlSerializableServices.ReadNodes(reader); } public void WriteXml(System.Xml.XmlWriter writer) { System.Runtime.Serialization.XmlSerializableServices.WriteNodes(writer, this.Nodes); } public System.Xml.Schema.XmlSchema GetSchema() { return null; } public static System.Xml.XmlQualifiedName ExportSchema(System.Xml.Schema.XmlSchemaSet schemas) { System.Runtime.Serialization.XmlSerializableServices.AddDefaultSchema(schemas, typeName); return typeName; } } Is this ok?? I'd expect to have an object created that contains properties for "code" and "message" s.t. you can then throw it by using something like ... throw new FaultException<groupFault>(new groupFault { code=100, message="error" }); ... (sorry for the lower-case type definitions, but this is generated code from the WSDL) Why doesn't the svcutil.exe generate those properties?? Some sources on the web suggested to add the /useSerializerForFaults option. I tried it, it doesn't work giving me an exception that the fault type is missing on the wsdl:portType declaration. Validation with several other tools succeeded however. Any help is VERY appreciated :) thx

  • Strange problems with PHP SOAP (private variable not persist + variables passed from client not work

    - by Tamas Gal
    I have a very strange problems in a PHP Soap implementation. I have a private variable in the Server class which contains the DB name for further reference. The private variable name is "fromdb". I have a public function on the soap server where I can set this variable. $client-setFromdb. When I call it form my client works perfectly and the fromdb private variable can be set. But a second soap client call this private variable loses its value... Here is my soap server setup: ini_set('soap.wsdl_cache_enabled', 0); ini_set('session.auto_start', 0); ini_set('always_populate_raw_post_data', 1); global $config_dir; session_start(); /*if(!$HTTP_RAW_POST_DATA){ $HTTP_RAW_POST_DATA = file_get_contents('php://input'); }*/ $server = new SoapServer("{$config_dir['template']}import.wsdl"); $server-setClass('import'); $server-setPersistence(SOAP_PERSISTENCE_SESSION); $server-handle(); Problem is that I passed this to the server: $client = new SoapClient('http://import.ingatlan.net/wsdl', array('trace' = 1)); $xml=''; $xml.=''; $xml.=''; $xml.=''; $xml.='Valaki'; $xml.=''; $xml.=''; $xml.=''; $xml.=''; $tarray = array("type" = 1, "xml" = $xml); try{ $s = $client-sendXml( $tarray ); print "$s"; } catch( SOAPFault $exception){ print "--- SOAP exception :{$exception}---"; print "LAST REQUEST :"; var_dump($client-_getLastRequest()); print "---"; print "LAST RESPONSE :".$client-_getLastResponse(); } So passed an Array of informations to the server. Then I got this exception: LAST REQUEST : <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><type>Array</type><xml/></SOAP-ENV:Body></SOAP-ENV:Envelope> Can you see the Array word between the type tag? Seems that the client only passed a reference or something like this. So I totaly missed :(

  • How to maxmise the largest contiguous block of memory in the Large Object Heap

    - by Unsliced
    The situation is that I am making a WCF call to a remote server which is returns an XML document as a string. Most of the time this return value is a few K, sometimes a few dozen K, very occasionally a few hundred K, but very rarely it could be several megabytes (first problem is that there is no way for me to know). It's these rare occasions that are causing grief. I get a stack trace that starts: System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at System.Xml.BufferBuilder.AddBuffer() at System.Xml.BufferBuilder.AppendHelper(Char* pSource, Int32 count) at System.Xml.BufferBuilder.Append(Char[] value, Int32 start, Int32 count) at System.Xml.XmlTextReaderImpl.ParseText() at System.Xml.XmlTextReaderImpl.ParseElementContent() at System.Xml.XmlTextReaderImpl.Read() at System.Xml.XmlTextReader.Read() at System.Xml.XmlReader.ReadElementString() at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderMDRQuery.Read2_getMarketDataResponse() at Microsoft.Xml.Serialization.GeneratedAssembly.ArrayOfObjectSerializer2.Deserialize(XmlSerializationReader reader) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events) at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle) at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) I've read around and it is because the Large Object Heap is just getting too fragmented, so even preceding the call with a quick check to StringBuilder.EnsureCapacity just causes the OutOfMemoryException to be thrown earlier (and because I'm guessing at what's needed, it might not actually need that much so my check is causing more problems than it is solving). Some opinions are that there's not much I can do about it. Some of the questions I've asked myself: Use less memory - have you checked for leaks? Yes. The memory usage goes up and down, but there's no fundamental growth that guarantees this to happen. Some of the times it fails, it succeeded at that stage previously. Transfer smaller amounts Not an option, this is a third party web service over which I have no control (or at least it would take a long time to resolve, in the meantime I still have a problem) Can you do something to the LOH to make it less likely to fail? ... now this is most fruitful course. It's a 32-bit process (it has to be for various political, technical and boring reasons) but there's normally hundreds of meg free (multiples of the largest amount for which we've seen failures). Can we monitor the LOH? Using perfmon I can track the size of the heaps, but I don't think there's a way to monitor the largest available contiguous block of memory. Question is: any advice or suggestions for things to try?

  • If I package a web application with the maven goal war:exploded, why won't pom.xml and pom.propertie

    - by Bernhard V
    Hi, I'm pretty new to Maven and I've noticed an interesting thing in the Maven WAR Plugin. When I package my Java web application with war:war, a zipped war is created. This war contains also the files pom.xml and pom.properties in the META-INF directory. But if I package my application with war:exploded and create an exploded war directory, those two files won't be included. Now I'm curious, why the pom.xml and the pom.properties aren't packaged into the exploded war. Besides those two files the contents of the exploded and the zipped war are equal. Is there a reason why the plugin omits pom.xml and pom.properties from the exploded war?

  • Using normalize-string XPath function from SQL XML query ?

    Hi, is it possible to run an SQL query, with an XPath "where" clause, and to trim trailing spaces before the comparison ? I have an SQL XML column, in which I have XML nodes with attributes which contain trailing spaces. I would like to find a given record, which has a specified attribute value - without the trailing spaces. When I try, I get... "There is no function '{http://www.w3.org/2004/07/xpath-functions}:normalize-space()'" I have tried the following (query 1 works, query 2 doesn't).

  • How to verify an XML digital signature in Cocoa?

    - by Geoff Smith
    I have a C# application that uses XML digital signatures to sign license files. I've used the standard Microsoft approach described here. I'm porting the application to the MAC and need to verify the signature. My general question is how best to do this? This is what I've done: I've used macport to install Aleksey's xmlsec1 library. Used the Chilkat library to convert my XML public key to a PEM file Chilkat.PublicKey pubKey = new Chilkat.PublicKey(); pubKey.LoadXml(publicKeyXml); pubKey.SaveOpenSslPemFile("publicKey.pem"); Compiled and ran the alekseys sample program. See (http://www.aleksey.com/xmlsec/api/xmlsec-verify-with-key.html) to verify an XML dsig. Result: my license files fail to validate. The call to xmlSecDSigCtxVerify fails with status=unknown. Now for my specific question: What can I do next? Geoff

I only have one package right now, ae, so I specify to only cover that: nosetests -w tests/unit --with-xunit --with-coverage --cover-package=ae And here are the results, which look good: Name Stmts Exec Cover Missing ---------------------------------------------- ae 1 1 100% ae.util 253 224 88% 39, 63-65, 284, 287, 362, 406 ---------------------------------------------- TOTAL 263 234 88% ---------------------------------------------------------------------- Ran 68 tests in 5.292s However when I run coverage xml, coverage pulls in more packages than necessary, including python email and logging packages which have nothing to do with my code. If I run coverage xml ae, I get this error: No source for code: '/home/wraith/dev/projects/trimurti/src/ae': [Errno 21] Is a directory: '/home/wraith/dev/projects/trimurti/src/ae' Is there a way to generate the XML for just the ae package?

  • how to pass an xml file to lxml to parse?

    - by BeeBand
    I'm trying to parse an xml file using lxml. xml.etree allowed me to simply pass the file name as a parameter to the parse function, so I attempted to do the same with lxml. My code: from lxml import etree from lxml import objectify file = "C:\Projects\python\cb.xml" tree = etree.parse(file) but I get the error: Traceback (most recent call last): File "cb.py", line 5, in <module> tree = etree.parse(file) File "lxml.etree.pyx", line 2698, in lxml.etree.parse (src/lxml/lxml.etree.c:4 9590) File "parser.pxi", line 1491, in lxml.etree._parseDocument (src/lxml/lxml.etre e.c:71205) File "parser.pxi", line 1520, in lxml.etree._parseDocumentFromURL (src/lxml/lx ml.etree.c:71488) File "parser.pxi", line 1420, in lxml.etree._parseDocFromFile (src/lxml/lxml.e tree.c:70583) File "parser.pxi", line 975, in lxml.etree._BaseParser._parseDocFromFile (src/ lxml/lxml.etree.c:67736) File "parser.pxi", line 539, in lxml.etree._ParserContext._handleParseResultDo c (src/lxml/lxml.etree.c:63820) File "parser.pxi", line 625, in lxml.etree._handleParseResult (src/lxml/lxml.e tree.c:64741) File "parser.pxi", line 565, in lxml.etree._raiseParseError (src/lxml/lxml.etr ee.c:64084) lxml.etree.XMLSyntaxError: AttValue: " or ' expected, line 2, column 26 What am I doing wrong?

  • Is it possible to mix orm.xml definitions with annotations when using JPA/hibernate ?

    - by hatchetman82
    I'm working on an application whihc supports using several DB vendors, with the table definitions being different for each DB type. The trouble is that the column definitions are not what hibernate expects, and so my entities contain a lot of @Column(..columnDefintion="..."...) annotations. To further complicate the issue, there's no way to specify a columnDefinition per DB. So I tried moving just the columnDefinition bits to an orm.xml file, and I have a Maven profile that bundles the correct file. JBoss 4.0.5/Hibernate 3.2.0GA fails to validate, and it seems it completely disregards the annotations given an xml file. Is there a way to make Hibernate "merge" the data from the xml with the annotations ?

  • Can we create a class from a xml file ?

    - by panzerschreck
    Hello, Is it possible to create a class dynamically by reading an xml file ( in java preferably) ? if yes, please provide pointers on how to do it. In the process of development, we have come up with a class that has 5 attributes, all these attributes correspond to an entry in the xml file, now if the user adds/modifies the xml entry the object corresponding to it must change automatically, one approach would be generate the source code, before compile time.Is there any other way ? Is there any common pattern to model such changes in the system ? Thanks,
