  • C#: Oracle Data Type Equivalence with OracleDbType

    - by Partial
    Situation: I am creating an app in C# that uses Oracle.DataAccess.Client (11g) to do certain operations on a Oracle database with stored procedures. I am aware that there is a certain enum (OracleDbType) that contains the Oracle data types, but I am not sure which one to use for certain types. Questions: What is the equivalent Oracle PL/SQL data type for each enumerated type in the OracleDbType enumeration? There are three types of integer (Int16, Int32, Int64) in the OracleDbType... how to know which one to use or are they all suppose to work?

  • Alternatives to LIMIT and OFFSET for paging in Oracle

    - by depr001
    Hello, I'm developing a web application and need to page ordered results. I normaly use LIMIT/OFFSET for this purpose. Which is the best way to page ordered results in Oracle? I've seen some samples using rownum and subqueries. Is that the way? Could you give me a sample for translating this SQL to Oracle: SELECT fieldA,fieldB FROM table ORDER BY fieldA OFFSET 5 LIMIT 14 (I'm using Oracle 10g, for what it's worth) Thanks!

  • bulk insert from Java into Oracle

    - by Will Glass
    I need to insert many small rows rapidly into Oracle. (5 fields). With MySQL, I break the inserts into groups of 100, then use one insert statement for every group of 100 inserts. But with Oracle, user feedback is that the mass inserts (anywhere from 1000-30000) are too slow. Is there a similar trick I can use to speed up the programmatic inserts from Java into Oracle?

Click here for a two-page printable conference overview (PDF). Big Data with CEP and SOA - September 25, 2012 - 14:15 Speaker: Markus Zirn, Oracle and Baz Kuthi, Avocent The "Big Data" trend is driving new kinds of IT projects that process machine-generated data. Such projects store and mine using Hadoop/ Map Reduce, but they also analyze streaming data via event-driven patterns, which can be called "Fast Data" complementary to "Big Data". This session highlights how "Big Data" and "Fast Data" design patterns can be combined with SOA design principles into modern, event-driven architectures. We will describe specific architectures that combines CEP, Distributed Caching, Event-driven Network, SOA Composites, Application Development Framework, as well as Hadoop. Architecture patterns include pre-processing and filtering event streams as close as possible to the event source, in memory master data for event pattern matching, event-driven user interfaces as well as distributed event processing. Focus is on how "Fast Data" requirements are elegantly integrated into a traditional SOA architecture. Markus Zirn is Vice President of Product Management covering Oracle SOA Suite, SOA Governance, Application Integration Architecture, BPM, BPM Solutions, Complex Event Processing and UPK, an end user learning solution. He is the author of “The BPEL Cookbook” (rated best book on Services Oriented Architecture in 2007) as well as “Fusion Middleware Patterns”. Previously, he was a management consultant with Booz Allen & Hamilton’s High Tech practice in Duesseldorf as well as San Francisco and Vice President of Product Marketing at QUIQ.

  • Simultaneously calling multiple methods on a WCF service from silverlight

    - by ola karlsson
    A while back I had to debug some performance issues in an existing Silverlight app, as the problem / solution was a bit obscure and finding info about it was quite tricky, I thought I’d share, maybe it can help the next person with this problem. The App On start, the app would do a number of calls to different methods on a WCF service, this to populate the UI with the necessary data. Recently one of those services had been changed and was now taking quite a bit longer than it used to. This was resulting in quite a long loading time for the whole UI, which was set up so it wouldn’t let the user interact with anything, until all the service calls had finished. First I broke out the longer running service call from the others, then removed the constraint that it had to be loaded for the UI in general to become responsive. I also added a loading indicator just on that area of the UI, thinking that the main UI would load while this particular section could keep loading independently. The Problem However this is where things started to get a bit strange. I found that even after these changes, the main UI wouldn’t activate until the long running call returned. So now, I did what I should have done to start with, I got Fiddler out and had a look at what was really happening. What I found was that, once the call to the long running service method was placed, all subsequent call were waiting for that one to return before executing. Not having really worked with WCF previously or knowing much about it in general, I was stumped… I knew of the issues where Silverlight is restricted by the browsers networking features in regards to number of simultaneous connections etc. However that just didn’t seem to be the issue here, you can clearly see in Fiddler that there’s numerous calls, but they’re just not returning. I thought of the problem maybe being in the WCF service, but the calls were really not that complicated and surely the service should be able to handle a lot more than what I was throwing at it! So I did what every developer does in this type of scenario, I hit the search engines. I did a whole bunch of searching on things like “multiple simultaneous WCF calls from Silverlight” and “Calling long running WCF services from Silverlight” etc. etc. This however, pretty much got me nowhere, I found a whole heap of resources on how to do WCF calls from Silverlight but most of them were very basic and of no use what so ever. The fog is clearing It wasn’t until I came across the term “ WCF blocking calls” and started incorporating that in my searches I started to get somewhere. Those searches quite quickly brought me to the following thread in the Silverlight forum “Long-running WCF call blocking subsequent calls” which discussed the exact problem I was facing and the best part, one of the guys there had the solution! The short answer is in the forum post and the guys answering, has also done a more extensive blog post about it called “Silverlight, WCF, and ASP.Net Configuration Gotchas” which covers it very well.  So come on what’s the solution?! I heard you ask, unless you’ve already gone to the links and looked it up ;) The Solution Well, it turns out that the issue is founded in a mix of Silverlight, Asp.Net and WCF, basically if you’re doing multiple calls to a single WCF web-service and you have Asp.Net session state enabled, the calls will be executed sequentially by the service, hence any long running calls will block subsequent ones. So why is Asp.Net session state effecting us, we’re working in Silverlight, right? We'll as mentioned earlier, by default Silverlight uses the browsers networking stack when doing service calls, hence to the WCF service, the call looks like it might as well be coming from a normal Asp.Net. To get around this, we look to a feature introduced in Silverlight 3, namely the Client HTTP Stack. The Client HTTP Stack to the rescue By using the following syntax (for example in our App.xaml.cs, Application_Startup method) WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp); we can set our Silverlight application to use the Client HTTP Stack, which incidentally solves our problem! By using Silverlights own networking stack, rather than that of the browser, we get around the Asp.Net - WCF session state issue. The above code specifies that all calls to addresses starting with “http://” should go through the client stack, this can actually be set more granular and you can specify it to be used only for certain domains etc. Summary The actual solution is well covered in the forum and blog posts I link to above. This post is more about sharing my experience, hopefully helping to spread the word about this and maybe make it a bit easier for the next poor guy with this issue to find the solution. Until next time, Ola

  • 5 Things I Learned About the IT Labor Shortage

    - by Oracle Accelerate for Midsize Companies
    by Jim Lein | Sr. Principal Product Marketing Director | Oracle Midsize Programs | @JimLein Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";} 5 Things I Learned About the IT Labor Shortage A gentle autumn breeze is nudging the last golden leaves off the aspen trees. It’s time to wrap up the series that I started back in April, “The Growing IT Labor Shortage: Are You Feeling It?” Even in a time of relatively high unemployment, labor shortages exist depending on many factors, including location, industry, IT requirements, and company size. According to Manpower Groups 2013 Talent Shortage Survey, 35% of hiring managers globally are having difficulty filling jobs. Their top three challenges in filling jobs are: 1. lack of technical competencies (hard skills) 2. Lack of available applicants 3. Lack of experience The same report listed Technicians as the most difficult position to fill in the United States For most companies, Human Capital and Talent Management have never been more strategic and they are striving for ways streamline processes, reduce turnover, and lower costs (see this Oracle whitepaper, “ Simplify Workforce Management and Increase Global Agility”). Everyone I spoke to—partner, customer, and Oracle experts—agreed that it can be extremely challenging to hire and retain IT talent in today’s labor market. And they generally agreed on the causes: a. IT is so pervasive that there are myriad moving parts requiring support and expertise, b. thus, it’s hard for university graduates to step in and contribute immediately without experience and specialization, c. big IT companies generally aren’t the talent incubators that they were in the freewheeling 90’s due to bottom line pressures that require hiring talent that can hit the ground running, and d. it’s often too expensive for resource-strapped midsize companies to invest the time and money required to get graduates up to speed. Here are my top lessons learned from my conversations with the experts. 1. A Better Title Would Have Been, “The Challenges of Finding and Retaining IT Talent That Matches Your Requirements” There are more applicants than jobs but it’s getting tougher and tougher to find individuals that perfectly fit each and every role. Top performing companies are increasingly looking to hire the “almost ready”, striving to keep their existing talent more engaged, and leveraging their employee’s social and professional networks to quickly narrow down candidate searches (here’s another whitepaper, “A Strategic Approach to Talent Management”). 2. Size Matters—But So Does Location Midsize companies must strive to build cultures that compete favorably with what large enterprises can offer, especially when they aren’t within commuting distance of IT talent strongholds. They can’t always match the compensation and benefits offered by large enterprises so it's paramount to offer candidates high quality of life and opportunities to build their resumes in alignment with their long term career aspirations. 3. Get By With a Little Help From Your Friends It doesn’t always make sense to invest time and money in training an employee on a task they will not perform frequently. Or get in a bidding war for talent with skills that are rare and in high demand. Many midsize companies are finding that it makes good economic sense to contract with partners for remote support rather than trying to divvy up each and every role amongst their lean staff. Internal staff can be assigned to roles that will have the highest positive impact on achieving organizational goals. 4. It’s Actually Both “What You Know” AND “Who You Know” If I was hiring someone today I would absolutely leverage the social and professional networks of my co-workers. Period. Most research shows that hiring in this manner is less expensive and time consuming AND produces better results. There is also some evidence that suggests new hires from employees’ networks have higher job performance and retention rates. 5. I Have New Respect for Recruiters and Hiring Managers My hats off to them—it’s not easy hiring and retaining top talent with today’s challenges. Check out the infographic, “A New Day: Taking HR from Chaos to Control”, on Oracle’s Human Capital Management solutions home page. You can also explore all of Oracle’s HCM solutions from that page based on your role. You can read all the posts in this series by clicking on the links in the right sidebar. Stay tuned…we’ll continue to post thought leadership on HCM and Talent Management topics.

  • Versioning Strategy for Service Interfaces JAR

    - by Colin Morelli
    I'm building a service oriented architecture composed (mostly) of Java-based services, each of which is a Maven project (in an individual repository) with two submodules: common, and server. The common module contains the service's interfaces that clients can include in their project to make service calls. The server submodule contains the code that actually powers the service. I'm now trying to figure out an appropriate versioning strategy for the interfaces, such that each interface change results in a new common jar, but changes to the server (so long as they don't impact the contract of the interfaces) receive the same common jar. I know this is pretty simple to do manually (simply increment the server version and don't touch the common one), but this project will be built and deployed by a CI server, and I'd like to come up with a strategy for automatically versioning these. The only thing I have been able to come up with so far is to have the CI server md5 the service interfaces.

  • Web Service - SOAP

    - by seth
    My experience with web services is slim and I'm trying to understand this a little bit more. I have done for instance a web service using visual studio. In order to use it, I add a web service reference in my projects and this creates a proxy and the use is pretty simple. Does this use SOAP? I ask this because i will be now facing a web service that i must communicate using SOAP with attachements and i'm trying to understand the concept behind this and the difference to what i have done so far. Will the proxy still be viable or do i need to create the XML by hand and post it to the web service? This concepts still confuse and so any help is appreciated. EDIT: I'm not developing the service, i will be just using it.

  • BizTalk 2009 - Service Instances: Last 100

    - by StuartBrierley
    Having previously talked about the lack of the traditional HAT in BizTalk 2009, the question then becomes how do you replicate some of the functionality that was previsouly relied on? I have already covered the Last 100 Messages Received, the Last 100 Messages Sent, and the Last 50 Suspended Messages queries so what about service instances? The BizTalk 2009 Group Hub allows you to search for suspended service instances and also running service instances, but not the two together. In BizTalk 2004 we had a query in HAT to return the last 100 service instances.  Lets create a direct replacement in the BizTalk 2009 Hatless environment. Basically we are creating a query to search for the last one hundred tracked service instances:

  • Cloud to On-Premise Connectivity Patterns

    - by Rajesh Raheja
    Do you have a requirement to convert an Opportunity in Salesforce.com to an Order/Quote in Oracle E-Business Suite? Or maybe you want the creation of an Oracle RightNow Incident to trigger an on-premise Oracle E-Business Suite Service Request creation for RMA and Field Scheduling? If so, read on. In a previous blog post, I discussed integrating TO cloud applications, however the use cases above are the reverse i.e. receiving data FROM cloud applications (SaaS) TO on-premise applications/databases that sit behind a firewall. Oracle SOA Suite is assumed to be on-premise with with Oracle Service Bus as the mediation and virtualization layer. The main considerations for the patterns are are security i.e. shielding enterprise resources; and scalability i.e. minimizing firewall latency. Let me use an analogy to help visualize the patterns: the on-premise system is your home - with your most valuable possessions - and the SaaS app is your favorite on-line store which regularly ships (inbound calls) various types of parcels/items (message types/service operations). You need the items at home (on-premise) but want to safe guard against misguided elements of society (internet threats) who may masquerade as postal workers and vandalize property (denial of service?). Let's look at the patterns. Pattern: Pull from Cloud The on-premise system polls from the SaaS apps and picks up the message instead of having it delivered. This may be done using Oracle RightNow Object Query Language or SOAP APIs. This is particularly suited for certain integration approaches wherein messages are trickling in, can be centralized and batched e.g. retrieving event notifications on an hourly schedule from the Oracle Messaging Service. To compare this pattern with the home analogy, you are avoiding any deliveries to your home and instead go to the post office/UPS/Fedex store to pick up your parcel. Every time. Pros: On-premise assets not exposed to the Internet, firewall issues avoided by only initiating outbound connections Cons: Polling mechanisms may affect performance, may not satisfy near real-time requirements Pattern: Open Firewall Ports The on-premise system exposes the web services that needs to be invoked by the cloud application. This requires opening up firewall ports, routing calls to the appropriate internal services behind the firewall. Fusion Applications uses this pattern, and auto-provisions the services on the various virtual hosts to secure the topology. This works well for service integration, but may not suffice for large volume data integration. Using the home analogy, you have now decided to receive parcels instead of going to the post office every time. A door mail slot cut out allows the postman can drop small parcels, but there is still concern about cutting new holes for larger packages. Pros: optimal pattern for near real-time needs, simpler administration once the service is provisioned Cons: Needs firewall ports to be opened up for new services, may not suffice for batch integration requiring direct database access Pattern: Virtual Private Networking The on-premise network is "extended" to the cloud (or an intermediary on-demand / managed service offering) using Virtual Private Networking (VPN) so that messages are delivered to the on-premise system in a trusted channel. Using the home analogy, you entrust a set of keys with a neighbor or property manager who receives the packages, and then drops it inside your home. Pros: Individual firewall ports don't need to be opened, more suited for high scalability needs, can support large volume data integration, easier management of one connection vs a multitude of open ports Cons: VPN setup, specific hardware support, requires cloud provider to support virtual private computing Pattern: Reverse Proxy / API Gateway The on-premise system uses a reverse proxy "API gateway" software on the DMZ to receive messages. The reverse proxy can be implemented using various mechanisms e.g. Oracle API Gateway provides firewall and proxy services along with comprehensive security, auditing, throttling benefits. If a firewall already exists, then Oracle Service Bus or Oracle HTTP Server virtual hosts can provide reverse proxy implementations on the DMZ. Custom built implementations are also possible if specific functionality (such as message store-n-forward) is needed. In the home analogy, this pattern sits in between cutting mail slots and handing over keys. Instead, you install (and maintain) a mailbox in your home premises outside your door. The post office delivers the parcels in your mailbox, from where you can securely retrieve it. Pros: Very secure, very flexible Cons: Introduces a new software component, needs DMZ deployment and management Pattern: On-Premise Agent (Tunneling) A light weight "agent" software sits behind the firewall and initiates the communication with the cloud, thereby avoiding firewall issues. It then maintains a bi-directional connection either with pull or push based approaches using (or abusing, depending on your viewpoint) the HTTP protocol. Programming protocols such as Comet, WebSockets, HTTP CONNECT, HTTP SSH Tunneling etc. are possible implementation options. In the home analogy, a resident receives the parcel from the postal worker by opening the door, however you still take precautions with chain locks and package inspections. Pros: Light weight software, IT doesn't need to setup anything Cons: May bypass critical firewall checks e.g. virus scans, separate software download, proliferation of non-IT managed software Conclusion The patterns above are some of the most commonly encountered ones for cloud to on-premise integration. Selecting the right pattern for your project involves looking at your scalability needs, security restrictions, sync vs asynchronous implementation, near real-time vs batch expectations, cloud provider capabilities, budget, and more. In some cases, the basic "Pull from Cloud" may be acceptable, whereas in others, an extensive VPN topology may be well justified. For more details on the Oracle cloud integration strategy, download this white paper.

  • Security settings for this service require 'Basic' Authentication

    - by Jake Rutherford
    Had an issue calling WCF service today. The following exception was being thrown when service was called:WebHost failed to process a request. Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/35320229 Exception: System.ServiceModel.ServiceActivationException: The service '/InteliChartVendorCommunication/VendorService.svc' cannot be activated due to an exception during compilation.  The exception message is: Security settings for this service require 'Basic' Authentication but it is not enabled for the IIS application that hosts this service..Ensured Basic authentication was indeed enabled in IIS before getting stumped on what actual issue could be. Turns out it was CustomErrors setting. Value was set to "off" vs "Off". Would have expected different exception from .NET (i.e. web.config parse exception) but it works now either way.

  • Consuming OData based Rest service in C# [en-US]

    - by ruimachado
    Nowadays comunication between applications is an active topic with daily usage and a large amount of pratical appliances. While developing an app in witch I had to consume an OData I found out that combining Linq with my code made this operation pretty easy.The algorithm to consume OData starts with adding a service reference to Visual Studio:After adding the service reference in wich you define the uri to the service, we start building our code.In your code the algorithm is the following:Define the Uri to your OData ServiceDefine the context of your odata, wich contains all entities exposed by the service.Query the context using LinqPrint the resultEasy and simple.Example code:01public static void Main(string[] args){02 03        Uri serviceUri= newUri("http://example.host.odataservice.net/service.svc", UriKind.Absolute);04        ODataService.ServiceEntities context = newODataService.ServiceEntities (serviceUri);05 06        context.Credentials = newSystem.Net.NetworkCredential(Username,Password);07 08         var query = from ServiceObject in context.YourEntity09                     select ServiceObject ;10 11        foreach (var myObject in query)12        {13            Console.WriteLine("\n Field1: {0} | Field2: {1}",14            myObject .Field1, myObject .Field2);15 16        }17}That’s it.Thank you,Rui Machadorpmachado.wordpress.com

    I need help in making my click intents work. I used to have them in my appwidgetprovider, but decided to move them into a service, but I am having trouble getting it to work. Below is the entire code from my intentservice: public class IntentService extends Service { static final String ACTION_UPDATE = "android.tristan.widget.digiclock.action.UPDATE_2"; private final static IntentFilter sIntentFilter; public int layoutID = R.layout.clock; int appWidgetIds = 0; static { sIntentFilter = new IntentFilter(); } @Override public IBinder onBind(Intent intent) { return null; } @Override public void onStart(Intent intent, int startId) { super.onStart(intent, startId); } @Override public void onCreate() { super.onCreate(); registerReceiver(onClickTop, sIntentFilter); registerReceiver(onClickBottom, sIntentFilter); Log.d("DigiClock IntentService", "IntentService Started."); } @Override public void onDestroy() { super.onDestroy(); unregisterReceiver(onClickTop); unregisterReceiver(onClickBottom); } private final BroadcastReceiver onClickTop = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if(intent.getAction().equals("android.tristan.widget.digiclock.CLICK")) { PackageManager packageManager = context.getPackageManager(); Intent alarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER); String clockImpls[][] = { {"HTC Alarm Clock", "com.htc.android.worldclock", "com.htc.android.worldclock.WorldClockTabControl" }, {"Standar Alarm Clock", "com.android.deskclock", "com.android.deskclock.AlarmClock"}, {"Froyo Nexus Alarm Clock", "com.google.android.deskclock", "com.android.deskclock.DeskClock"}, {"Moto Blur Alarm Clock", "com.motorola.blur.alarmclock", "com.motorola.blur.alarmclock.AlarmClock"} }; boolean foundClockImpl = false; for(int i=0; i<clockImpls.length; i++) { String vendor = clockImpls[i][0]; String packageName = clockImpls[i][1]; String className = clockImpls[i][2]; try { ComponentName cn = new ComponentName(packageName, className); ActivityInfo aInfo = packageManager.getActivityInfo(cn, PackageManager.GET_META_DATA); alarmClockIntent.setComponent(cn); foundClockImpl = true; } catch (NameNotFoundException e) { Log.d("Error, ", vendor + " does not exist"); } } if (foundClockImpl) { Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE); vibrator.vibrate(50); final RemoteViews views = new RemoteViews(context.getPackageName(), layoutID); views.setOnClickPendingIntent(R.id.TopRow, PendingIntent.getActivity(context, 0, new Intent(context, DigiClock.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK), PendingIntent.FLAG_UPDATE_CURRENT)); AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views); alarmClockIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(alarmClockIntent); } } } }; private final BroadcastReceiver onClickBottom = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if(intent.getAction().equals("android.tristan.widget.digiclock.CLICK_2")) { PackageManager calendarManager = context.getPackageManager(); Intent calendarIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER); String calendarImpls[][] = { {"HTC Calendar", "com.htc.calendar", "com.htc.calendar.LaunchActivity" }, {"Standard Calendar", "com.android.calendar", "com.android.calendar.LaunchActivity"}, {"Moto Blur Calendar", "com.motorola.blur.calendar", "com.motorola.blur.calendar.LaunchActivity"} }; boolean foundCalendarImpl = false; for(int i=0; i<calendarImpls.length; i++) { String vendor = calendarImpls[i][0]; String packageName = calendarImpls[i][1]; String className = calendarImpls[i][2]; try { ComponentName cn = new ComponentName(packageName, className); ActivityInfo aInfo = calendarManager.getActivityInfo(cn, PackageManager.GET_META_DATA); calendarIntent.setComponent(cn); foundCalendarImpl = true; } catch (NameNotFoundException e) { Log.d("Error, ", vendor + " does not exist"); } } if (foundCalendarImpl) { Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE); vibrator.vibrate(50); final RemoteViews views2 = new RemoteViews(context.getPackageName(), layoutID); views2.setOnClickPendingIntent(R.id.BottomRow, PendingIntent.getActivity(context, 0, new Intent(context, DigiClock.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK), PendingIntent.FLAG_UPDATE_CURRENT)); AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views2); calendarIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(calendarIntent); } } }; }; ;}; What am I doing wrong here?

  • What is this service called in English?

    - by moomoochoo
    DETAILS I'm not familiar with server administration and am trying to find the name of a particular service offered by a Japanese website provider. The service is for a dedicated server. I have attached a picture detailing the service below. The left side of the picture shows the server without the service. The right side shows the server with the service. Once I know the name of the service I will Google it, but any additional information in regards to the pros and cons of such a service would be much appreciated. Thanks!

  • tab completion for service command on debian

    - by markus
    I have two systems with debian squeeze installed. On one system when I type: service <TAB> it shows me all available service (from /etc/init.d) on the other system it shows me all files from the current directory. Does anyone know which setting changes that behaviour ? UPDATE: The file /etc/bash_completion.d/service was missing. I copied it from the machine where it is working. If I type complete -p | grep service it shows me: complete -F _service service On the machine where it is not working that command shows me nothing. I executed complete -F _service service in the command line, after that, the command service <TAB> shows me: service -su: completion: function `_service' not found this function is defined in the service file I recently copied, for some reasons it can't be found ...

  • Bluetooth -> service discovery failed

    - by Kaiser
    Hello, I'm writing an application which is able to communicate with my PC. I have used the Bluetooth functionalities of the SDK 2.1. I can find devices, get their MAC address, create a RFCOMM socket, but when I start the connection, I get the following error message : Service discovery failed. 1)Is it because of the UUID which is not the same on my application and on my PC ? 2)How can I get the correct UUID on my PC ? If I write a such application, is my Nexus one the client or the server ? Thanks a lot for your help !

  • How to use WIX to deploy and run WCF service

    - by Giampaolo
    Hi I am trying to make an installer which deploys my wcf service, at the moment it is creating the virtual directory, but when i try connect my app to it, i get a CommunicationException was unhandled by user code The remote server returned an error: NotFound. I notice that if i create a virtual directory manually that it will connect and work, so i'm assuming IIS is doing something behind my back which is making it work. This is the code i am using to create the virtual directory,please note this is inside a iis:WebSite tag if more information is needed please let me know. <iis:WebVirtualDir Id="VAWebService" Directory="VAWebService" Alias="VAWebService" > <iis:WebApplication Id="VAWebService" Name="VAWebService" AllowSessions="yes" WebAppPool="VA_AppPool" /> <iis:WebDirProperties Id="MyWebSite_Properties" AnonymousAccess="yes" WindowsAuthentication="no" DefaultDocuments="service1.svc" AccessSSL="yes" AccessSSL128="yes" AccessSSLMapCert="yes" AccessSSLNegotiateCert="yes" AccessSSLRequireCert="yes" Read="yes" Write="yes" Execute="yes" Script="yes" /> </iis:WebVirtualDir> Does any one know how to fix this? any help would be appreciated. Thanks

  • Consuming SAP Web Service from ASP.Net

    - by mehmet6parmak
    Hi, Next week i am supposed to develop an asp.net application which will connect to SAP, retrieve some data, change them and send back to SAP. We decided to use web services to achieve this and now i just want to know what diffuculties may i face with? I have URL of WSDL of the Web Service, will it be enough for me to adding web reference and giving the WSDL's URL? How will i authenticate? And Will it be the same with consuming normal web services? Also i wonder is there anybody that can share a .NET dll that can be used in visual studio 2008? There are some articles relating how to create such a dll using SAP .Net Connector and visual studio 2003 but i could not find anybody sharing the resulting dll under their post. Thanks...

  • Silverlight 4.0 question - synchronous calls to asmx web service

    - by Anvar
    Hi, I have Silverlight problem. I have to deal with fairly large legacy application that has some web services exposed (regular asmx, not wcf). What I need to do is to build Silverlight app that consumes those web services. Due to business logic I need to have the same web method to be called from Silverlight app synchronously. I was able to build web services consumption but only asynchronously because that would be default Silverlight behavior. Is there a way to make asynchronous calls synchronous in Silverlight? I looked here and googled around but came across only wcf examples. I would appreciate if somebody would get me a code example for regular asmx web service. I use Silverlight 4.0. Thanks!
