  • Power Management - Sleep / Wake up Server when accessed

    - by KP65
    I have a headless HP Proliant Microserver with ubuntu installed. This machine has samba shares on it serving media and I usually rdp or ssh into it. Now my issue is I want the machine to go into sleep mode(so the state is saved from ram to the harddrive) and it will seem like it is turned off after an hour of idling. If there is any attempt to access the samba share through LAN I would like it to wake up. Now my motherboard supports this function, can anyone point me in the right direction for achieving this easily? Thanks

  • Game Asset Management

    - by user964123
    I am making my first small mobile game in C# XNA. Lets say I have 3 screens, the main menu, options and game screen. A single game session usually lasts for 1 min, so the user will alternate frequently between the main menu and game screen. Therefore, once I load the textures for either screen, I want to keep them in memory to avoid frequent reloading. Both screens share some assets like their background textures, but differ in others. The first solution I came up with is making 2 texture factory classes, MainScreenAssetFactory and GameScreenAssetFactory, each with their own content manager, and ill store them in a globally accessible point so that they persist after either screen is destroyed. There is also a OptionsScreenAssetFactory, but that I dont want to cache it since the options screen is rarely visited. A typical Factory would look something like this public class MainScreenAssetFactory { private readonly ContentManager contentManager; public MainScreenAssetFactory(IServiceProvider serviceProvider, string rootDirectory) { contentManager = new ContentManager(serviceProvider) { RootDirectory = rootDirectory }; } public Texture2D ListElementBackground { get { return return contentManager.Load<Texture2D>("UserTab"); } } public Texture2D ListElementBulletPoint { get { return return contentManager.Load<Texture2D>("TabIcon"); } } public Texture2D LoggedOutUser { get { return return contentManager.Load<Texture2D>("LoggedOutUser"); } } } Since both Main, Options and Game Screen share some common resources, instead of loading them more than once, I created another class CommonAssetTexFactory which holds the common stuff and stays in-memory during the app lifetime. For example, this class gets passed to the options screen when it is created. However, given my small game with its few assets, I am already finding this solution cumbersome and inflexible. Changing anything would require looking to see if its already in the common factory, and if not, modifying existing factories and so on. And this is just considering textures currently, i didnt add sound files yet. I cant imagine bigger games with thousands of resources using this approach. A better idea must exist. Would someone please enlighten me?

  • New Tuxedo White Papers

    - by todd.little
    As part of the Tuxedo 11gR1 release, I've written two new white papers on Tuxedo. One is called "Tuxedo in a SOA World" and discusses how Tuxedo fits into SOA based applications. It covers most of the various connectivity options from Tuxedo into SOA environments and gives guidance as to which connectivity options are best suited for a particular application requirement. The other white paper "SCA: Bringing Modern SOA Programing to Tuxedo" is of a more technical bent and focuses on using the SCA features in SALT to easily build SOA based applications on Tuxedo without using a lot of technical APIs. In fact, services built using SALT's SCA support don't require any technical APIs, just pure business logic, and SCA clients need at most a couple of API calls, simply to look up a service. You can find these two new white papers as well as some additional white papers at http://www.oracle.com/technology/products/tuxedo/index.html.

The previous posts were: JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue JMS Step 3 - Using the QueueReceive.java Sample Program to Read a Message from a JMS Queue JMS Step 4 - How to Create an 11g BPEL Process Which Writes a Message Based on an XML Schema to a JMS Queue JMS Step 5 - How to Create an 11g BPEL Process Which Reads a Message Based on an XML Schema from a JMS Queue This example leads you through the creation of an Oracle database Advanced Queue and the related WebLogic server objects in order to use AQ JMS in connection with a SOA composite. If you have not already done so, I recommend you look at the previous posts in this series, as they include steps which this example builds upon. The following examples will demonstrate how to write and read from the queue from a SOA process. 1. Recap and Prerequisites In the previous examples, we created a JMS Queue, a Connection Factory and a Connection Pool in the WebLogic Server Console. Then we wrote and deployed BPEL composites, which enqueued and dequeued a simple XML payload. AQ JMS allows you to interoperate with database Advanced Queueing via JMS in WebLogic server and therefore take advantage of database features, while maintaining compliance with the JMS architecture. AQ JMS uses the WebLogic JMS Foreign Server framework. A full description of this functionality can be found in the following Oracle documentation Oracle® Fusion Middleware Configuring and Managing JMS for Oracle WebLogic Server 11g Release 1 (10.3.6) Part Number E13738-06 7. Interoperating with Oracle AQ JMS http://docs.oracle.com/cd/E23943_01/web.1111/e13738/aq_jms.htm#CJACBCEJ For easier reference, this sample will use the same names for the objects as in the above document, except for the name of the database user, as it is possible that this user already exists in your database. We will create the following objects Database Objects Name Type AQJMSUSER Database User MyQueueTable Advanced Queue (AQ) Table UserQueue Advanced Queue WebLogic Server Objects Object Name Type JNDI Name aqjmsuserDataSource Data Source jdbc/aqjmsuserDataSource AqJmsModule JMS System Module AqJmsForeignServer JMS Foreign Server AqJmsForeignServerConnectionFactory JMS Foreign Server Connection Factory AqJmsForeignServerConnectionFactory AqJmsForeignDestination AQ JMS Foreign Destination queue/USERQUEUE eis/aqjms/UserQueue Connection Pool eis/aqjms/UserQueue 2. Create a Database User and Advanced Queue The following steps can be executed in the database client of your choice, e.g. JDeveloper or SQL Developer. The examples below use SQL*Plus. Log in to the database as a DBA user, for example SYSTEM or SYS. Create the AQJMSUSER user and grant privileges to enable the user to create AQ objects. Create Database User and Grant AQ Privileges sqlplus system/password as SYSDBA GRANT connect, resource TO aqjmsuser IDENTIFIED BY aqjmsuser; GRANT aq_user_role TO aqjmsuser; GRANT execute ON sys.dbms_aqadm TO aqjmsuser; GRANT execute ON sys.dbms_aq TO aqjmsuser; GRANT execute ON sys.dbms_aqin TO aqjmsuser; GRANT execute ON sys.dbms_aqjms TO aqjmsuser; Create the Queue Table and Advanced Queue and Start the AQ The following commands are executed as the aqjmsuser database user. Create the Queue Table connect aqjmsuser/aqjmsuser; BEGIN dbms_aqadm.create_queue_table ( queue_table = 'myQueueTable', queue_payload_type = 'sys.aq$_jms_text_message', multiple_consumers = false ); END; / Create the AQ BEGIN dbms_aqadm.create_queue ( queue_name = 'userQueue', queue_table = 'myQueueTable' ); END; / Start the AQ BEGIN dbms_aqadm.start_queue ( queue_name = 'userQueue'); END; / The above commands can be executed in a single PL/SQL block, but are shown as separate blocks in this example for ease of reference. You can verify the queue by executing the SQL command SELECT object_name, object_type FROM user_objects; which should display the following objects: OBJECT_NAME OBJECT_TYPE ------------------------------ ------------------- SYS_C0056513 INDEX SYS_LOB0000170822C00041$$ LOB SYS_LOB0000170822C00040$$ LOB SYS_LOB0000170822C00037$$ LOB AQ$_MYQUEUETABLE_T INDEX AQ$_MYQUEUETABLE_I INDEX AQ$_MYQUEUETABLE_E QUEUE AQ$_MYQUEUETABLE_F VIEW AQ$MYQUEUETABLE VIEW MYQUEUETABLE TABLE USERQUEUE QUEUE Similarly, you can view the objects in JDeveloper via a Database Connection to the AQJMSUSER. 3. Configure WebLogic Server and Add JMS Objects All these steps are executed from the WebLogic Server Administration Console. Log in as the webLogic user. Configure a WebLogic Data Source The data source is required for the database connection to the AQ created above. Navigate to domain > Services > Data Sources and press New then Generic Data Source. Use the values:Name: aqjmsuserDataSource JNDI Name: jdbc/aqjmsuserDataSource Database type: Oracle Database Driver: *Oracle’ Driver (Thin XA) for Instance connections; Versions:9.0.1 and later Connection Properties: Enter the connection information to the database containing the AQ created above and enter aqjmsuser for the User Name and Password. Press Test Configuration to verify the connection details and press Next. Target the data source to the soa server. The data source will be displayed in the list. It is a good idea to test the data source at this stage. Click on aqjmsuserDataSource, select Monitoring > Testing > soa_server1 and press Test Data Source. The result is displayed at the top of the page. Configure a JMS System Module The JMS system module is required to host the JMS foreign server for AQ resources. Navigate to Services > Messaging > JMS Modules and select New. Use the values: Name: AqJmsModule (Leave Descriptor File Name and Location in Domain empty.) Target: soa_server1 Click Finish. The other resources will be created in separate steps. The module will be displayed in the list.   Configure a JMS Foreign Server A foreign server is required in order to reference a 3rd-party JMS provider, in this case the database AQ, within a local WebLogic server JNDI tree. Navigate to Services > Messaging > JMS Modules and select (click on) AqJmsModule to configure it. Under Summary of Resources, select New then Foreign Server. Name: AqJmsForeignServer Targets: The foreign server is targeted automatically to soa_server1, based on the JMS module’s target. Press Finish to create the foreign server. The foreign server resource will be listed in the Summary of Resources for the AqJmsModule, but needs additional configuration steps. Click on AqJmsForeignServer and select Configuration > General to complete the configuration: JNDI Initial Context Factory: oracle.jms.AQjmsInitialContextFactory JNDI Connection URL: <empty> JNDI Properties Credential:<empty> Confirm JNDI Properties Credential: <empty> JNDI Properties: datasource=jdbc/aqjmsuserDataSource This is an important property. It is the JNDI name of the data source created above, which points to the AQ schema in the database and must be entered as a name=value pair, as in this example, e.g. datasource=jdbc/aqjmsuserDataSource, including the “datasource=” property name. Default Targeting Enabled: Leave this value checked. Press Save to save the configuration. At this point it is a good idea to verify that the data source was written correctly to the config file. In a terminal window, navigate to $MIDDLEWARE_HOME/user_projects/domains/soa_domain/config/jms  and open the file aqjmsmodule-jms.xml . The foreign server configuration should contain the datasource name-value pair, as follows:   <foreign-server name="AqJmsForeignServer">         <default-targeting-enabled>true</default-targeting-enabled>         <initial-context-factory>oracle.jms.AQjmsInitialContextFactory</initial-context-factory>         <jndi-property>           <key> datasource </key>           <value> jdbc/aqjmsuserDataSource </value>         </jndi-property>   </foreign-server> </weblogic-jms> Configure a JMS Foreign Server Connection Factory When creating the foreign server connection factory, you enter local and remote JNDI names. The name of the connection factory itself and the local JNDI name are arbitrary, but the remote JNDI name must match a specific format, depending on the type of queue or topic to be accessed in the database. This is very important and if the incorrect value is used, the connection to the queue will not be established and the error messages you get will not immediately reflect the cause of the error. The formats required (Remote JNDI names for AQ JMS Connection Factories) are described in the section Configure AQ Destinations  of the Oracle® Fusion Middleware Configuring and Managing JMS for Oracle WebLogic Server document mentioned earlier. In this example, the remote JNDI name used is   XAQueueConnectionFactory  because it matches the AQ and data source created earlier, i.e. thin with AQ. Navigate to JMS Modules > AqJmsModule > AqJmsForeignServer > Connection Factories then New.Name: AqJmsForeignServerConnectionFactory Local JNDI Name: AqJmsForeignServerConnectionFactory Note: this local JNDI name is the JNDI name which your client application, e.g. a later BPEL process, will use to access this connection factory. Remote JNDI Name: XAQueueConnectionFactory Press OK to save the configuration. Configure an AQ JMS Foreign Server Destination A foreign server destination maps the JNDI name on the foreign JNDI provider to the respective local JNDI name, allowing the foreign JNDI name to be accessed via the local server. As with the foreign server connection factory, the local JNDI name is arbitrary (but must be unique), but the remote JNDI name must conform to a specific format defined in the section Configure AQ Destinations  of the Oracle® Fusion Middleware Configuring and Managing JMS for Oracle WebLogic Server document mentioned earlier. In our example, the remote JNDI name is Queues/USERQUEUE , because it references a queue (as opposed to a topic) with the name USERQUEUE. We will name the local JNDI name queue/USERQUEUE, which is a little confusing (note the missing “s” in “queue), but conforms better to the JNDI nomenclature in our SOA server and also allows us to differentiate between the local and remote names for demonstration purposes. Navigate to JMS Modules > AqJmsModule > AqJmsForeignServer > Destinations and select New.Name: AqJmsForeignDestination Local JNDI Name: queue/USERQUEUE Remote JNDI Name:Queues/USERQUEUE After saving the foreign destination configuration, this completes the JMS part of the configuration. We still need to configure the JMS adapter in order to be able to access the queue from a BPEL processt. 4. Create a JMS Adapter Connection Pool in Weblogic Server Create the Connection Pool Access to the AQ JMS queue from a BPEL or other SOA process in our example is done via a JMS adapter. To enable this, the JmsAdapter in WebLogic server needs to be configured to have a connection pool which points to the local connection factory JNDI name which was created earlier. Navigate to Deployments > Next and select (click on) the JmsAdapter. Select Configuration > Outbound Connection Pools and New. Check the radio button for oracle.tip.adapter.jms.IJmsConnectionFactory and press Next. JNDI Name: eis/aqjms/UserQueue Press Finish Expand oracle.tip.adapter.jms.IJmsConnectionFactory and click on eis/aqjms/UserQueue to configure it. The ConnectionFactoryLocation must point to the foreign server’s local connection factory name created earlier. In our example, this is AqJmsForeignServerConnectionFactory . As a reminder, this connection factory is located under JMS Modules > AqJmsModule > AqJmsForeignServer > Connection Factories and the value needed here is under Local JNDI Name. Enter AqJmsForeignServerConnectionFactory  into the Property Value field for ConnectionFactoryLocation. You must then press Return/Enter then Save for the value to be accepted. If your WebLogic server is running in Development mode, you should see the message that the changes have been activated and the deployment plan successfully updated. If not, then you will manually need to activate the changes in the WebLogic server console.Although the changes have been activated, the JmsAdapter needs to be redeployed in order for the changes to become effective. This should be confirmed by the message Remember to update your deployment to reflect the new plan when you are finished with your changes. Redeploy the JmsAdapter Navigate back to the Deployments screen, either by selecting it in the left-hand navigation tree or by selecting the “Summary of Deployments” link in the breadcrumbs list at the top of the screen. Then select the checkbox next to JmsAdapter and press the Update button. On the Update Application Assistant page, select “Redeploy this application using the following deployment files” and press Finish. After a few seconds you should get the message that the selected deployments were updated. The JMS adapter configuration is complete and it can now be used to access the AQ JMS queue. You can verify that the JNDI name was created correctly, by navigating to Environment > Servers > soa_server1 and View JNDI Tree. Then scroll down in the JNDI Tree Structure to eis and select aqjms. This concludes the sample. In the following post, I will show you how to create a BPEL process which sends a message to this advanced queue via JMS.

  • SOA Suite Integration: Part 1: Building a Web Service

    - by Anthony Shorten
    Over the next few weeks I will be posting blog entries outlying the SOA Suite integration of the Oracle Utilities Application Framework. This will illustrate how easy it is to integrate by providing some samples. I will use a consistent set of features as examples. The examples will be simple and while will not illustrate ALL the possibilities it will illustrate the relative ease of integration. Think of them as a foundation. You can obviously build upon them. Now, to ease a few customers minds, this series will certainly feature the latest version of SOA Suite and the latest version of Oracle Utilities Application Framework but the principles will apply to past versions of both those products. So if you have Oracle SOA Suite 10g or are a customer of Oracle Utilities Application Framework V2.1 or above most of what I will show you will work with those versions. It is just easier in Oracle SOA Suite 11g and Oracle Utilities Application Framework V4.x. This first posting will not feature SOA Suite at all but concentrate on the capability for the Oracle Utilities Application Framework to create Web Services you can use for integration. The XML Application Integration (XAI) component of the Oracle Utilities Application Framework allows product objects to be exposed as XML based transactions or as Web Services (or both). XAI was written before Web Services became fashionable and has allowed customers of our products to provide a consistent interface into and out of our product line. XAI has been enhanced over the last few years to take advantages of the maturing landscape of Web Services in the market place to a point where it now easier to integrate to SOA infrastructure. There are a number of object types that can be exposed as Web Services: Maintenance Objects – These are the lowest level objects that can be exposed as Web Services. Customers of past versions of the product will be familiar with XAI services based upon Maintenance Objects as they used to be the only method of generating Web Services. These are still supported for background compatibility but are starting to become less popular as they were strict in their structure and were solely attribute based. To generate Maintenance Object based Web Services definition you need to use the XAI Schema Editor component. Business Objects – In Oracle Utilities Application Framework V2.1 we introduced the concept of Business Objects. These are site or industry specific objects that are based upon Maintenance Objects. These allow sites to respecify, in configuration, the structure and elements of a Maintenance Object and other Business Objects (they are true objects with support for inheritance, polymorphism, encapsulation etc.). These can be exposed as Web Services. Business Services – As with Business Objects, we introduced Business Services in Oracle Utilities Application Framework V2.1 which allowed applications services and query zones to be expressed as custom services. These can then be exposed as Web Services via the Business Service definition. Service Scripts - As with Business Objects and Business Services, we introduced Service Scripts in Oracle Utilities Application Framework V2.1. These allow services and/objects to be combined into complex objects or simply expose common routines as callable scripts. These can also be defined as Web Services. For the purpose of this series we will restrict ourselves to Business Objects. The techniques can apply to any of the objects discussed above. Now, lets get to the important bit of this blog post, the creation of a Web Service. To build a Business Object, you first logon to the product and navigate to the Administration Menu by selecting the Admin Menu from the Menu action on left top of the screen (next to Home). A popup menu will appear with the menu’s available. If you do not see the Admin menu then you do not have authority to use it. Here is an example: Navigate to the B menu and select the + symbol next to the Business Object menu item. This indicates that you want to ADD a new Business Object. This menu will appear if you are running Alphabetic mode in your installation (I almost forgot that point). You will be presented with the Business Object maintenance screen. You will fill out the following on the first tab (at a minimum): Business Object – The name of the Business Object. Typically you will make it descriptive and also prefix with CM to denote it as a customization (you can easily find it if you prefix it). As I running this on my personal copy of the product I will use my initials as the prefix and call the sample Web Service “AS-User”. Description – A short description of the object to tell others what it is used for. For my example, I will use “Anthony Shorten’s User Object”. Detailed Description – You can add a long description to help other developers understand your object. I am just going to specify “Anthony Shorten’s Test Object for SOA Suite Integration”. Maintenance Object – As this Business Service is going to be based upon a Maintenance Object I will specify the desired Maintenance Object. In this example, I have decided to use the Framework object USER. Now, I chose this for a number of reasons. It is meaningful, simple and is across all our product lines. I could choose ANY maintenance object I wished to expose (including any custom ones, if I had them). Parent Business Object – If I was not using a Maintenance Object but building a child Business Object against another Business Object, then I would specify the Parent Business Object here. I am not using Parent’s so I will leave this blank. You either use Parent Business Object or Maintenance Object not both. Application Service – Business Objects like other objects are subject to security. You can attach an Application Service to an object to specify which groups of users (remember services are attached to user groups not users) have appropriate access to the object. I will use a default service provided with the product, F1-DFLTS ,as this is just a demonstration so I do not have to be too sophisticated about security. Instance Control – This allows the object to create instances in its objects. You can specify a Business Object purely to hold rules. I am being simple here so I will set it to Allow New Instances to allow the Business Object to be used to create, read, update and delete user records. The rest of the tab I will leave empty as I want this to be a very simple object. Other options allow lots of flexibility. The contents should look like this: Before saving your work, you need to navigate to the Schema tab and specify the contents of your object. I will save some time. When you create an object the schema will only contain the basic root elements of the object (in fact only the schema tag is visible). When you go to the Schema Tab, on the dashboard you will see a BO Schema zone with a solitary button. This will allow you to Generate the Schema for you from our metadata. Click on the Generate button to generate a basic schema from the metadata. You will now see a Schema with the element tags and references to the metadata of the Maintenance object (in the mapField attribute). I could spend a while outlining all the ways you can change the schema with defaults, formatting, tagging etc but the online help has plenty of great examples to illustrate this. You can use the Schema Tips zone in the for more details of the available customizations. Note: The tags are generated from the language pack you have installed. The sample is English so the tags are in English (which is the base language of all installations). If you are using a language pack then the tags will be generated in the language of the user that generated the object. At this point you can save your Business Object by pressing the Save action. At this point you have a basic Business Object based on the USER maintenance object ready for use but it is not defined as a Web Service yet. To do this you need to define the newly created Business Object as an XAI Inbound Service. The easiest and quickest way is to select + off the XAI Inbound Service off the context menu on the Business Object maintenance screen. This will prepopulate the service definition with the following: Adapter – This will be set to Business Adaptor. This indicates that the service is either Business Object, Business Service or Service Script based. Schema Type – Whether the object is a Business Object, Business Service or Service Script. In this case it is a Business Object. Schema Name – The name of the object. In this case it is the Business Object AS-User. Active – Set to Yes. This means the service is available upon startup automatically. You can enable and disable services as needed. Transaction Type – A default transaction type as this is Business Object Service. More about this in later postings. In our case we use the default Read. This means that if we only specify data and not a transaction type then the product will assume you want to issue a read against the object. You need to fill in the following: XAI Inbound Service – The name of the Web Service. Usually people use the same name as the underlying object , in the case of this example, but this can match your sites interfacing standards. By the way you can define multiple XAI Inbound Services/Web Services against the same object if you want. Description and Detail Description – Documentation for your Web Service. I just supplied some basic documentation for this demonstration. You can now save the service definition. Note: There are lots of other options on this screen that allow for behavior of your service to be specified. I will leave them blank for now. When you save the service you are issued with two new pieces of information. XAI Inbound Service Id is a randomly generated identifier used internally by the XAI Servlet. WSDL URL is the WSDL standard URL used for integration. We will take advantage of that in later posts. An example of the definition is shown below: Now you have defined the service but it will only be available when the next server restart or when you flush the data cache. XAI Inbound Services are cached for performance so the cache needs to be told of this new service. To refresh the cache you can use the Admin –> X –> XAI Command menu item. From the command dropdown select Refresh Registry and press Send Command. You will see an XML of the command sent to the server (the presence of the XML means it is finished). If you have an error around the authorization, then check your default user and password settings on the XAI Options menu item. Be careful with flushing the cache as the cache is shared (unless of course you are the only Web Service user on the system – In that case it only affects you). The Web Service is NOW available to be used. To perform a simple test of your new Web Service, navigate to the Admin –> X –> XAI Submission menu item. You will see an open XML request tab. You need to type in the request XML you want to test in the Main tab. The first tag is the XAI Inbound Service Name and the elements are as per your schema (minus the schema tag itself as that is only used internally). My example is as follows (I want to return the details of user SYSUSER) – Remember to close tags. Hitting the Save button will issue the XML and return the response according to the Business Object schema. Now before you panic, you noticed that it did not ask for credentials. It propagates the online credentials to the service call on this function. You now have a Web Service you can use for integration. We will reuse this information in subsequent posts. The process I just described can be used for ANY object in the system you want to expose. This whole process at a minimum can take under a minute. Obviously I only showed the basics but you can at least get an appreciation of the ease of defining a Web Service (just by using a browser). The next posts now build upon this. Hope you enjoyed the post.

  • SOA 11g Technology Adapters – ECID Propagation

    - by Greg Mally
    Overview Many SOA Suite 11g deployments include the use of the technology adapters for various activities including integration with FTP, database, and files to name a few. Although the integrations with these adapters are easy and feature rich, there can be some challenges from the operations perspective. One of these challenges is how to correlate a logical business transaction across SOA component instances. This correlation is typically accomplished via the execution context ID (ECID), but we lose the ECID correlation when the business transaction spans technologies like FTP, database, and files. A new feature has been introduced in the Oracle adapter JCA framework to allow the propagation of the ECID. This feature is available in the forthcoming SOA Suite 11.1.1.7 (PS6). The basic concept of propagating the ECID is to identify somewhere in the payload of the message where the ECID can be stored. Then two Binding Properties, relating to the location of the ECID in the message, are added to either the Exposed Service (left-hand side of composite) or External Reference (right-hand side of composite). This will give the JCA framework enough information to either extract the ECID from or add the ECID to the message. In the scenario of extracting the ECID from the message, the ECID will be used for the new component instance. Where to Put the ECID When trying to determine where to store the ECID in the message, you basically have two options: Add a new optional element to your message schema. Leverage an existing element that is not used in your schema. The best scenario is that you are able to add the optional element to your message since trying to find an unused element will prove difficult in most situations. The schema will be holding the ECID value which looks something like the following: 11d1def534ea1be0:7ae4cac3:13b4455735c:-8000-00000000000002dc Configuring Composite Services/References Now that you have identified where you want the ECID to be stored in the message, the JCA framework needs to have this information as well. The two pieces of information that the framework needs relates to the message schema: The namespace for the element in the message. The XPath to the element in the message. To better understand this, let's look at an example for the following database table: When an Exposed Service is created via the Database Adapter Wizard in the composite, the following schema is created: For this example, the two Binding Properties we add to the ReadRow service in the composite are: <!-- Properties for the binding to propagate the ECID from the database table --> <property name="jca.ecid.nslist" type="xs:string" many="false">  xmlns:ns1="http://xmlns.oracle.com/pcbpel/adapter/db/top/ReadRow"</property> <property name="jca.ecid.xpath" type="xs:string" many="false">  /ns1:EcidPropagationCollection/ns1:EcidPropagation/ns1:ecid</property> Notice that the property called jca.ecid.nslist contains the targetNamespace defined in the schema and the property called jca.ecid.xpath contains the XPath statement to the element. The XPath statement also contains the appropriate namespace prefix (ns1) which is defined in the jca.ecid.nslist property. When the Database Adapter service reads a row from the database, it will retrieve the ECID value from the payload and remove the element from the payload. When the component instance is created, it will be associated with the retrieved ECID and the payload contains everything except the ECID element/value. The only time the ECID is visible is when it is stored safely in the resource technology like the database, a file, or a queue. Simple Database/File/JMS Example This section contains a simplified example of how the ECID can propagate through a database table, a file, and JMS queue. The composite for the example looks like the following: The flow of this example is as follows: Invoke database insert using the insertwithecidbpelprocess_client_ep Service. The InsertWithECIDBPELProcess adds a row to the database via the Database Adapter. The JCA Framework adds the ECID to the message prior to inserting. The ReadRow Service retrieves the record and the JCA Framework extracts the ECID from the message. The ECID element is removed from the message. An instance of ReadRowBPELProcess is created and it is associated with the retried ECID. The ReadRowBPELProcess now writes the record to the file system via the File Adapter. The JCA Framework adds the ECID to the message prior to writing the message to file. The ReadFile Service retrieves the record from the file system and the JCA Framework extracts the ECID from the message. The ECID element is removed from the message. An instance of ReadFileBPELProcess is created and it is associated with the retried ECID. The ReadFileBPELProcess now enqueues the message via the JMS Adapter. The JCA Framework adds the ECID to the message prior to enqueuing the message. The DequeueMessage Service retrieves the record and the JCA Framework extracts the ECID from the message. The ECID element is removed from the message. An instance of DequeueMessageBPELProcess is created and it is associated with the retried ECID. The logical flow ends. When viewing the Flow Trace in the Enterprise Manger, you will now see all the instances correlated via ECID: Please check back here when SOA Suite 11.1.1.7 is released for this example. With the example you can run it yourself and reinforce what has been shared in this blog via a hands-on experience. One final note: the contents of this blog may be included in the official SOA Suite 11.1.1.7 documentation, but you will still need to come here to get the example.

  • Overwrite SOA expiry in a bind9 slave name server.

    - by Joachim Breitner
    I run a slave name server of a domain that I do not have full control over (i.e. changing the SOA is not possibly). The SOA specifies an expiry time of one week. For various reasons, I’d like to override that value on my specific slave server to something larger. Is there a way to do that? N.B: I know that for the refresh and retry fields, bind9 provides the options min-refresh-time, max-refresh-time, min-retry-time and max-retry-time to overrule the SOA, as mentioned in the documentation. For some reason this just does not inclucde expiry.

  • SOA Checklist

    - by pat.shepherd
    In a recent meeting, the customer brought up a valid question: “How do I know if a problem/system is a good candidate for using SOA (vs. using old but trusted techniques).  I put this checklist together.  If you can answer yes to 2 or more of these, it might well be a good candidate.  This is V1, and I will likely update it over time.  Comments (that are not spam or sales pitches) appreciated. Part of the conversation was also around the fact that SOA has two faces to it; one is around the obvious reuse possibilities. The other, that often gets forgotten, is that SOA provides goodness in terms of simplifying integration even where opportunities to reuse those integrations are small; at least the integrations are standards-based and more flexible.  I did not write a lot of verbiage about each of them, for example “Business Process” implies that there is a set of step-wise actions that need to take place in a coordinated fashion that include integrating with systems (and sometimes people for approvals and other human-only actions) in the process.

  • Connecting Clinical and Administrative Processes: Oracle SOA Suite for Healthcare Integration

    - by Mala Ramakrishnan
    One of the biggest IT challenges facing today’s health care industry is the difficulty finding reliable, secure, and cost-effective ways to exchange information. Payers and providers need versatile platforms for enterprise-wide information sharing. Clinicians require accurate information to provide quality care to patients while administrators need integrated information for all facets of the business operation. Both sides of the organization must be able to access information from research and development systems, practice management systems, claims systems, financial systems, and many others. Externally, these organizations must share claims data, patient records, pharmaceutical data, lab reports, and diagnostic information among third party entities—all while complying with emerging standards for formatting, processing, and storing electronic health records (EHR). Service-oriented architecture (SOA) enables developers to integrate many types of software applications, databases and computing platforms within a particular health network as well as with community, state, and national health information exchanges. The Oracle SOA Suite for healthcare integration is designed to provide healthcare organizations with comprehensive integration capabilities within a unified middleware platform, as well as with healthcare libraries and templates for streamlining healthcare IT projects. It reduces the need for specialized skills and enforces an enterprise-wide view of critical healthcare data.  Here is a new white paper that details more about this offering: Oracle SOA Suite for Healthcare Integration

  • SOA Starting Point: Methods for Service Identification and Definition

    As more and more companies start to incorporate a Service Oriented Architectural design approach into their existing enterprise systems, it creates the need for a standardized integration technology. One common technology used by companies is an Enterprise Service Bus (ESB). An ESB, as defined by Progress Software, connects and mediates all communications and interactions between services. In essence an ESB is a form of middleware that allows services to communicate with one another regardless of framework, environment, or location. With the emergence of ESB, a new emphasis is now being placed on approaches that can be used to determine what Web services should be built. In addition, what order should these services be built? In May 2011, SOA Magazine published an article that identified 10 common methods for identifying and defining services. SOA’s Ten Common Methods for Service Identification and Definition: Business Process Decomposition Business Functions Business Entity Objects Ownership and Responsibility Goal-Driven Component-Based Existing Supply (Bottom-Up) Front-Office Application Usage Analysis Infrastructure Non-Functional Requirements  Each of these methods provides various pros and cons in regards to their use within the design process. I personally feel that during a design process, multiple methodologies should be used in order to accurately define a design for a system or enterprise system. Personally, I like to create a custom cocktail derived from combining these methodologies in order to ensure that my design fits with the project’s and business’s needs while still following development standards and guidelines. Of these ten methods, I am particularly fond of Business Process Decomposition, Business Functions, Goal-Driven, Component-Based, and routinely use them in my designs.  Works Cited Hubbers, J.-W., Ligthart, A., & Terlouw , L.

  • Comprehensive solution for managing patches, event viewing, change management, inventory, etc

    - by Holocryptic
    I'm looking for a solution that incorporates most or all of the following: Patch Management, Server event viewing/tracking, AD change management, ticketing and internal/external kb, remote access - ability to shadow user sessions or create new ones, imaging, and inventory. Our environments contains Windows Servers and ESXi Hosts (We're not completely virtual, but we're moving that direction). Various Cisco and Linksys switches and firewalls. This is a tall order, and I don't know if it can be done on a reasonable budget. I've looked and found some questions on SF that deal with some of this: http://serverfault.com/questions/72015/active-directory-management-tools-for-medium-sized-forest-less-than-1000-users http://serverfault.com/questions/4021/are-there-any-tools-to-do-change-management-with-active-directory-group-policy http://serverfault.com/questions/21752/what-is-a-good-patch-update-management-server What I'm ideally looking for is a reasonably cheap solution that integrates the features into a central interface. We're a non-profit, so money is a limiting factor (the cheaper, the better; but we have a max of $15k). What we are trying to avoid is having to deal with multiple vendors, while maintaining scalability (we're creating more sites that we'll have to manage). Is this possible, or will we have to cobble together something to make it work for us?

  • Case Management API by Koen van Dijk

    - by JuergenKress
    Case Management is a new addition to Oracle BPM in release 11.1.1.1.7 (PS6). This new release contains the Case Management engine, see blog Léon at  http://leonsmiers.blogspot.nl/ for more details.  However, currently this release does not contain a case portal. The case management API's, just like the already existing Oracle BPM API's, help in developing a portal page with relative ease. This blog will use some real life examples from the EURent casemanagement application and portal application developed by Oracle. The Oracle BPM Case Management API is a Java Based API that enables developers to programmatically access the new Case Management functionalities. It is an elaborate API that can access all the functionalities of Oracle Case Management. I will describe two of those functionalities in this blog: retrieving case data as DOM (http://www.w3.org/DOM/) and attaching a document to a case. Libraries First of all when creating a Case Management project you will need to attach the following libraries: These contain all the classes that are in the Case Management API. Service client To do anything with the BPM CaseManagement API in general it is necessary to create a CaseManagementServiceClient Object. The Case Management service client is the central piece of the Case Management API. It can be used to retrieve two different types of services. The first is the case stream service and the case service. The case stream service contains functionality to upload and download documents to and from a case. The second one is the CaseService. This service contains all the other functionality acting upon a case including but not limited to: Read the complete article here.

  • How to deal with project managers who micromanage?

    - by entens
    Perhaps I'm just naive, but when I try to decipher the wall of tasks I'm targeted to do over the course of a week, I just can't help but think whoever builds the project schedule needs to get some remedial training on basic project management. For example, I am assigned 13 tasks today, the shortest lasting .13 days (default time metric in Microsoft Project), and the longest lasting .75 days. I can't help but think that it is blatant micromanagement scheduling projects in sub 10 minute intervals. The effects of management are becoming evident in slipped tasks, resource assignment exceeding capacity by a factor of two at some points in time, and spending more time clearing tasks and figuring out what comes next than actually doing work. How can I convince the project manager to create tasks with larger duration and to see the larger picture?

  • How can we unify business goals and technical goals?

    - by BAM
    Some background I work at a small startup: 4 devs, 1 designer, and 2 non-technical co-founders, one who provides funding, and the other who handles day-to-day management and sales. Our company produces mobile apps for target industries, and we've gotten a lot of lucky breaks lately. The outlook is good, and we're confident we can make this thing work. One reason is our product development team. Everyone on the team is passionate, driven, and has a great sense of what makes an awesome product. As a result, we've built some beautiful applications that we're all proud of. The other reason is the co-founders. Both have a brilliant business sense (one actually founded a multi-million dollar company already), and they have close ties in many of the industries we're trying to penetrate. Consequently, they've brought in some great business and continue to keep jobs in the pipeline. The problem The problem we can't seem to shake is how to bring these two awesome advantages together. On the business side, there is a huge pressure to deliver as fast as possible as much as possible, whereas on the development side there is pressure to take your time, come up with the right solution, and pay attention to all the details. Lately these two sides have been butting heads a lot. Developers are demanding quality while managers are demanding quantity. How can we handle this? Both sides are correct. We can't survive as a company if we build terrible applications, but we also can't survive if we don't sell enough. So how should we go about making compromises? Things we've done with little or no success: Work more (well, it did result in better quality and faster delivery, but the dev team has never been more stressed out before) Charge more (as a startup, we don't yet have the credibility to justify higher prices, so no one is willing to pay) Extend deadlines (if we charge the same, but take longer, we'll end up losing money) Things we've done with some success: Sacrifice pay to cut costs (everyone, from devs to management, is paid less than they could be making elsewhere. In return, however, we all have creative input and more flexibility and freedom, a typical startup trade off) Standardize project management (we recently started adhering to agile/scrum principles so we can base deadlines on actual velocity, not just arbitrary guesses) Hire more people (we used to have 2 developers and no designers, which really limited our bandwidth. However, as a startup we can only afford to hire a few extra people.) Is there anything we're missing or doing wrong? How is this handled at successful companies? Thanks in advance for any feedback :)

  • Request/Response pattern in SOA implementation

    - by UserControl
    In some enterprise-like project (.NET, WCF) i saw that all service contracts accept a single Request parameter and always return Response: [DataContract] public class CustomerRequest : RequestBase { [DataMember] public long Id { get; set; } } [DataContract] public class CustomerResponse : ResponseBase { [DataMember] public CustomerInfo Customer { get; set; } } where RequestBase/ResponseBase contain common stuff like ErrorCode, Context, etc. Bodies of both service methods and proxies are wrapped in try/catch, so the only way to check for errors is looking at ResponseBase.ErrorCode (which is enumeration). I want to know how this technique is called and why it's better compared to passing what's needed as method parameters and using standard WCF context passing/faults mechanisms?
