• Ops Center Solaris 11 IPS Repository Management: Using ISO Images

  - by S Stelting

  Please join us for a live WebEx presentation of this topic on Tuesday, November 20th at 9am MDT. Details for the call are provided below: https://oracleconferencing.webex.com/oracleconferencing/j.php?ED=209834017&UID=1512096072&PW=NYTVlZTYxMzdm&RT=MiMxMQ%3D%3D Meeting password: oracle123 Call-in toll-free number: 1-866-682-4770 International numbers: http://www.intercall.com/oracle/access_numbers.htm Conference Code: 762 9343 # Security Code: 7777 # With Enterprise Manager Ops Center 12c, you can provision, patch, monitor and manage Oracle Solaris 11 instances. To do this, Ops Center creates and maintains a Solaris 11 Image Packaging System (IPS) repository on the Enterprise Controller. During the Enterprise Controller configuration, you can load repository content directly from Oracle's Support Web site and subsequently synchronize the repository as new content becomes available. Of course, you can also use Solaris 11 ISO images to create and update your Ops Center repository. There are a few excellent reasons for doing this: You're running Ops Center in disconnected mode, and don't have Internet access on your Enterprise Controller You'd rather avoid the bandwidth associated with live synchronization of a Solaris 11 package repository This demo will show you how to use Solaris 11 ISO images to set up and update your Ops Center repository. Prerequisites This tip assumes that you've already installed the Enterprise Controller on a Solaris 11 OS instance and that you're ready for post-install configuration. In addition, there are specific Ops Center and OS version requirements depending on which version of Solaris 11 you plan to install.You can get full details about the requirements in the Release Notes for Ops Center 12c update 2. Additional information is available in the Ops Center update 2 Readme document. Part 1: Using a Solaris 11 ISO Image to Create an Ops Center Repository Step 1 – Download the Solaris 11 Repository Image The Oracle Web site provides a number of download links for official Solaris 11 images. Among those links is a two-part downloadable repository image, which provides repository content for Solaris 11 SPARC and X86 architectures. In this case, I used the Solaris 11 11/11 image. First, navigate to the Oracle Web site and accept the OTN License agreement: http://www.oracle.com/technetwork/server-storage/solaris11/downloads/index.html Next, download both parts of the Solaris 11 repository image. I recommend using the Solaris 11 11/11 image, and have provided the URLs here: http://download.oracle.com/otn/solaris/11/sol-11-1111-repo-full.iso-ahttp://download.oracle.com/otn/solaris/11/sol-11-1111-repo-full.iso-b Finally, use the cat command to generate an ISO image you can use to create your repository: # cat sol-11-1111-repo-full.iso-a sol-11-1111-repo-full.iso-b > sol-11-1111-repo-full.iso The process is very similar if you plan to set up a Solaris 11.1 release in Ops Center. In that case, navigate to the Solaris 11 download page, accept the license agreement and download both parts of the Solaris 11.1 repository image. Use the cat command to create a single ISO image for Solaris 11.1 Step 2 – Mount the Solaris 11 ISO Image in your Local Filesystem Once you have created the Solaris 11 ISO file, use the mount command to attach it to your local filesystem. After the image has been mounted, you can browse the repository from the ./repo subdirectory, and use the pkgrepo command to verify that Solaris 11 recognizes the content: Step 3 – Use the Image to Create your Ops Center Repository When you have confirmed the repository is available, you can use the image to create the Enterprise Controller repository. The operation will be slightly different depending on whether you configure Ops Center for Connected or Disconnected Mode operation.For connected mode operation, specify the mounted ./repo directory in step 4.1 of the configuration wizard, replacing the default Web-based URL. Since you're synchronizing from an OS repository image, you don't need to specify a key or certificate for the operation. For disconnected mode configuration, specify the Solaris 11 directory along with the path to the disconnected mode bundle downloaded by running the Ops Center harvester script: Ops Center will run a job to import package content from the mounted ISO image. A synchronization job can take several hours to run – in my case, the job ran for 3 hours, 22 minutes on a SunFire X4200 M2 server. During the job, Ops Center performs three important tasks: Synchronizes all content from the image and refreshes the repository Updates the IPS publisher information Creates OS Provisioning profiles and policies based on the content When the job is complete, you can unmount the ISO image from your Enterprise Controller. At that time, you can view the repository contents in your Ops Center Solaris 11 library. For the Solaris 11 11/11 release, you should see 8,668 packages and patches in the contents. You should also see default deployment plans for Solaris 11 provisioning. As part of the repository import, Ops Center generates plans and profiles for desktop, small and large servers for the SPARC and X86 architecture. Part 2: Using a Solaris 11 SRU to update an Ops Center Repository It's possible to use the same approach to upgrade your Ops Center repository to a Solaris 11 Support Repository Update, or SRU. Each SRU provides packages and updates to Solaris 11 - for example, SRU 8.5 provided the packaged for Oracle VM Server for SPARC 2.2 SRUs are available for download as ISO images from My Oracle Support, under document ID 1372094.1. The document provides download links for all SRUs which have been released by Oracle for Solaris 11. SRUs are cumulative, so later versions include the packages from earlier SRUs. After downloading an ISO image for an SRU, you can mount it to your local filesystem using a mount command similar to the one shown for Solaris 11 11/11. When the ISO image is mounted to the file system, you can perform the Add Content action from the Solaris 11 Library to synchronize packages and patches from the mounted image. I used the same mount point, so the repository URL was file://mnt/repo once again: After the synchronization of an SRU is complete, you can verify its content in the Solaris 11 library using the search function. The version pattern is 0.175.0.#, where the # is the same value as the SRU. In this example, I upgraded to SRU 1. The update job ran in just under 8 minutes, and a quick search shows that 22 software components were added to the repository: It's also possible to search for "Support Repository Update" to confirm the SRU was successfully added to the repository. Details on any of the update content are available by clicking the "View Details" button under the Packages/Patches entry.

• Mock Repository vs. Real Repository w/Mocked Data

  - by n8wrl

  I must be doing something fundamentally wrong. I am implmenting my repositories and then testing them with mocked data. All is well. Now I want to test my domain objects so I point them at mock repositories. But I'm finding that I have to re-implement logic from the 'real' repositories into the mocks, or, create 'helper classes' that encapsulate the logic and interact with the repositories (real or mock), and then I have to test those too. So what am I missing - why implement and test mock repositories when I could use the real ones with mocked data? EDIT: To clarify, by 'mocked data' I do not hit the actual database. I have a 'DB mock layer' I can insert under the real repositories that returns known-data.

• AIA Artefakte im Oracle Enterprise Repository

  - by Hans Viehmann

  Das Oracle Enterprise Repository (OER) ist die zentrale Stelle zur Verwaltung von SOA Artefakten aller Art, mit dem Ziel, den gesamten Lebenszyklus dieser Artefakte zu begleiten. Es ist wesentliche Grundlage für deren Wiederverwendung, für die Ermittlung von Abhängigkeiten, wie auch für die Bestimmung des Wertes dieser Artefakte, was wiederum für den Nutzen der SOA Implementierung von Bedeutung ist. In AIA 11g wird die aktuelle Version des OER unterstützt und wird zusätzlich ergänzt durch die Project Lifecycle Workbench, in der die funktionale Spezifikation, die Aufteilung der Prozesse, oder beispielsweise die Generierung des Deployment Plans erfolgt.Für die Bereitstellung der Artefakte des Foundation Pack 11g gibt es inzwischen ein zugehöriges AIA Solution Pack für OER, mit dem die entsprechenden Strukturen, sowie die Bestandteile des Foundation Packs 11g, also EBOs, EBMs, EBSs, usw. unabhängig von einer AIA Installation direkt importiert werden können. Das Pack steht auch auf support.oracle.com bereit und kann hier heruntergeladen werden.

• Solution with multiple projects and (GitHub) single issue tracker and repository

  - by Luiz Damim

  I have a Visual Studio solution with multiple projects: Acme.Core Acme.Core.Tests Acme.UI.MvcSite1 Acme.UI.MvcSite2 Acme.UI.WinformsApp1 Acme.UI.WinformsApp2 ... The entire solution is checked-in in a single GitHub (private) repo. Acme.Core contains our business logic and all UI projects are deployables. UI projects have different requirements and features, but some of them are implemented in more than one project. All issues are opened in a single issue tracker and classified using labels ([MvcSite1], [WinformsApp1], etc) but I'm thinking it's starting to get messy. Is it ok to use a single repository and issue tracker to track multiple projects in one solution?

• Netbeans 7.01 in 12.04 repository, no javascript support

  - by Danielinux

  Hi I've installed Netbeans 7.0.1 from ubuntu 12.04 repository, i'm having many issues, The most important is that I cannot have help in writing javascript. Each .js file appear as a usual text file and even javascript sintax in jsp pages appear as normal text. I've already checked in tools -- options -- misc-- files and i cannot find there the .js association and the text/javascript mime-type. Another issue, really awfull, is that I cannot access CVS server if i do not run Netbeans as a root user. Someone had the same troubles i listed above? Have you some tips for solving them avoiding to install a newer version from Netbeans website? thanks in advance

• Aggregate root & Repository dilemma

  - by mateoc

  I am in a big dilemma here. I have a League, Team and Player entities. I have created a repo for the league only as a Team cannot exists without a League. At first I had bounded the players only with the team but then I realised I would have a problem with free agents so I also bounded the players to the league. Then I was wondering if a player could exists without a League or a Team and I am totally confused to that question. So would you make a player repository or include them in the league repo? Thanks

• Generic object to object mapping with parametrized constructor

  - by Rody van Sambeek

  I have a data access layer which returns an IDataRecord. I have a WCF service that serves DataContracts (dto's). These DataContracts are initiated by a parametrized constructor containing the IDataRecord as follows: [DataContract] public class DataContractItem { [DataMember] public int ID; [DataMember] public string Title; public DataContractItem(IDataRecord record) { this.ID = Convert.ToInt32(record["ID"]); this.Title = record["title"].ToString(); } } Unfortanately I can't change the DAL, so I'm obliged to work with the IDataRecord as input. But in generat this works very well. The mappings are pretty simple most of the time, sometimes they are a bit more complex, but no rocket science. However, now I'd like to be able to use generics to instantiate the different DataContracts to simplify the WCF service methods. I want to be able to do something like: public T DoSomething<T>(IDataRecord record) { ... return new T(record); } So I'd tried to following solutions: Use a generic typed interface with a constructor. doesn't work: ofcourse we can't define a constructor in an interface Use a static method to instantiate the DataContract and create a typed interface containing this static method. doesn't work: ofcourse we can't define a static method in an interface Use a generic typed interface containing the new() constraint doesn't work: new() constraint cannot contain a parameter (the IDataRecord) Using a factory object to perform the mapping based on the DataContract Type. does work, but: not very clean, because I now have a switch statement with all mappings in one file. I can't find a real clean solution for this. Can somebody shed a light on this for me? The project is too small for any complex mapping techniques and too large for a "switch-based" factory implementation.

• DDD Model Design and Repository Persistence Performance Considerations

  - by agarhy

  So I have been reading about DDD for some time and trying to figure out the best approach on several issues. I tend to agree that I should design my model in a persistent agnostic manner. And that repositories should load and persist my models in valid states. But are these approaches realistic practically? I mean its normal for a model to hold a reference to a collection of another type. Persisting that model should mean persist the entire collection. Fine. But do I really need to load the entire collection every time I load the model? Probably not. So I can have specialized repositories. Some that load maybe a subset of the object graph via DTOs and others that load the entire object graph. But when do I use which? If I have DTOs, what's stopping client code from directly calling them and completely bypassing the model? I can have mappers and factories to create my models from DTOs maybe? But depending on the design of my models that might not always work. Or it might not allow my models to be created in a valid state. What's the correct approach here?

• Using an Apt Repository for Paid Software Updates

  - by Scott Warren

  I'm trying to determine a way to distribute software updates for a hosted/on-site web application that may have weekly and/or monthly updates. I don't want the customers who use the on-site product to have to worry about updating it manually I just want it to download and install automatically ala Google Chrome. I'm planning on providing an OVF file with Ubuntu and the software installed and configured. My first thought on how to distributed software is to create six Apt repositories/channels (not sure which would be better at this point) that will be accessed through SSH using keys so if a customer doesn't renew their subscription we can disable their account: Beta - Used internally on test data to check the package for major defects. Internal - Used internally on live data to check the package for defects (dog fooding stage). External 1 - Deployed to 1% of our user base (randomly selected) to check for defects. External 9 - Deployed to 9% of our user base (randomly selected) to check for defects. External 90 - Deployed to the remaining 90% of users. Hosted - Deployed to the hosted environment. It will take a sign off at each stage to move into the next repository in case problems are reported. My questions to the community are: Has anyone tried something like this before? Can anyone see a downside to this type of a procedure? Is there a better way?

• What's the best structure for a repository?

  - by jpmelos

  I've looked into many open source software repositories, and I've found some common elements and somethings people do in different fashion from one another. For example, every repository has a README file, a INSTALL file, a COPYING file and stuff like that. Other things differ: Some projects, like git, have their source code in the root level, while others have the source code in a src/ folder and others, like the Linux kernel, have the source code spread in different folders in root level, that divide code by areas; Some have their tests in a t/ folder, while others in a tests/ folder, or named otherwise; Some have files about submitting patches and who the maintainers are, and those might be inside some Documentation/ or in the root level. Are there recommendations? A best practice? For example: personally, I don't like the code in the root level, git-fashion. It looks messy and confuses one trying to start as a contributor (especially because they have some code inside folders, and scripts in the root level as well, it's really messy). If I were to start a project of my own and wanted to start right from the start, are there recommendations? Best practices? How can I make a clean and clear structure? Thank you!

• need help connecting to bitbucket repository with sourceTree on windows 8

  - by pythonian29033

  I'm having trouble adding and cloning my repo on bitbucket to the sourceTree app, we're only starting with this now and we're a small company, so there's not much knowledge around this. now I've gone through The documentation on sourceTree for help, but I've noticed when I select my repo on bitbucket, it uses the repo url I select and appends a .git at the end. Then a notice message says This is not a valid source path / URL, but when I click Details... I get a dialogBox with nothing in it and an ok button. and when I'm done entering the details the 'Clone' button remains disabled. Is this Windows 8 or am I actually doing something wrong? Now I usually use ubuntu, but we just got these new ASUS ultrabooks at work and it's a pain to install any linux Distro on here. So I'm stuck with windows 8

• How do I create stand alone packages from ubuntu repository

  - by tachyons

  Is it possible to create a stand alone deb packages by merging dependancies without manual repacking.?? I've looked at this question but it doesn't really answer what I'm trying to achieve above. if possible how to do it? update 1 No tools available yet(?) So what about creating new deb package containing all packages which will copy dependencies to the cache and executing main package. Is it possible? update 2 Above method appears to be impossible because dpkg cant handle more than one operation at a time. Some scripts may can do it update 3 this tool is very helpful but it currently wont support oneric and above still waiting for more generic tool Thanks in advance

• How can I write a clean Repository without exposing IQueryable to the rest of my application?

  - by Simucal

  So, I've read all the Q&A's here on SO regarding the subject of whether or not to expose IQueryable to the rest of your project or not (see here, and here), and I've ultimately decided that I don't want to expose IQueryable to anything but my Model. Because IQueryable is tied to certain persistence implementations I don't like the idea of locking myself into this. Similarly, I'm not sure how good I feel about classes further down the call chain modifying the actual query that aren't in the repository. So, does anyone have any suggestions for how to write a clean and concise Repository without doing this? One problem I see, is my Repository will blow up from a ton of methods for various things I need to filter my query off of. Having a bunch of: IEnumerable GetProductsSinceDate(DateTime date); IEnumberable GetProductsByName(string name); IEnumberable GetProductsByID(int ID); If I was allowing IQueryable to be passed around I could easily have a generic repository that looked like: public interface IRepository<T> where T : class { T GetById(int id); IQueryable<T> GetAll(); void InsertOnSubmit(T entity); void DeleteOnSubmit(T entity); void SubmitChanges(); } However, if you aren't using IQueryable then methods like GetAll() aren't really practical since lazy evaluation won't be taking place down the line. I don't want to return 10,000 records only to use 10 of them later. What is the answer here? In Conery's MVC Storefront he created another layer called the "Service" layer which received IQueryable results from the respository and was responsible for applying various filters. Is this what I should do, or something similar? Have my repository return IQueryable but restrict access to it by hiding it behind a bunch of filter classes like GetProductByName, which will return a concrete type like IList or IEnumerable?

• Can a loosely typed language be considered true object oriented?

  - by user61852

  Can a loosely typed programming language like PHP be really considered object oriented? I mean, the methods don't have returning types and method parameters has no declared type either. Doesn't class design require methods to have a return type? Don't methods signatures have specifically-typed parameters? How can OOP techniques help you code in PHP if you always have to check the types of parameters received because the language doesn't enforce types? Please, if I'm wrong, explain it to me. When you design things using UML, then code classes in PHP with no return-typed methods and no-type parameters... Is the code really compliant with the UML design? You spend time designing the architecture of your software, then the compiler doesn't force the programmer to follow your design while coding, letting he/she assign any object variable to any other variable with no "type-mismatch" warning.

• DDD: service contains two repository

  - by tikhop

  Does it correct way to have two repository inside one service and will it be an application or domain service? Suppose I have a Passenger object that should contains Passport (government id) object. I am getting Passenger from PassengerRepository. PassengerRepository create request to server and obtain data (json) than parse received data and store inside repository. I have confused because I want to store Passport as Entity and put it to PassportRepository but all information about password contains inside json than i received above. I guess that I should create a PassengerService that will be include PassengerRepository and PassportRepository with several methods like removePassport, addPassport, getAllPassenger and etc. UPDATE: So I guess that the better way is represent Passport as VO and store all passports inside Passenger aggregate. However there is another question: Where I should put the methods (methods calls server api) for management passenger's passport. I think the better place is so within Passenger aggregate.

• Saving complex aggregates using Repository Pattern

  - by Kevin Lawrence

  We have a complex aggregate (sensitive names obfuscated for confidentiality reasons). The root, R, is composed of collections of Ms, As, Cs, Ss. Ms have collections of other low-level details. etc etc R really is an aggregate (no fair suggesting we split it!) We use lazy loading to retrieve the details. No problem there. But we are struggling a little with how to save such a complex aggregate. From the caller's point of view: r = repository.find(id); r.Ps.add(factory.createP()); r.Cs[5].updateX(123); r.Ms.removeAt(5); repository.save(r); Our competing solutions are: Dirty flags Each entity in the aggregate in the aggregate has a dirty flag. The save() method in the repository walks the tree looking for dirty objects and saves them. Deletes and adds are a little trickier - especially with lazy-loading - but doable. Event listener accumulates changes. Repository subscribes a listener to changes and accumulates events. When save is called, the repository grabs all the change events and writes them to the DB. Give up on repository pattern. Implement overloaded save methods to save the parts of the aggregate separately. The original example would become: r = repository.find(id); r.Ps.add(factory.createP()); r.Cs[5].updateX(123); r.Ms.removeAt(5); repository.save(r.Ps); repository.save(r.Cs); repository.save(r.Ms); (or worse) Advice please! What should we do?

• NHibernate does not update entity when repository is passed by constructor

  - by Alex

  Hi everybody, I am developing with NHibernate for the first time in conjunction with ASP.NET MVC and StructureMap. The CodeCampServer serves as a great example for me. I really like the different concepts which were implemented there and I can learn a lot from it. In my controllers I use Constructur Dependency Injection to get an instance of the specific repository needed. My problem is: If I change an attribute of the customer the customer's data is not updated in the database, although Commit() is called on the transaction object (by a HttpModule). public class AccountsController : Controller { private readonly ICustomerRepository repository; public AccountsController(ICustomerRepository repository) { this.repository = repository; } public ActionResult Save(Customer customer) { Customer customerToUpdate = repository .GetById(customer.Id); customerToUpdate.GivenName = "test"; //<-- customer does not get updated in database return View(); } } On the other hand this is working: public class AccountsController : Controller { [LoadCurrentCustomer] public ActionResult Save(Customer customer) { customer.GivenName = "test"; //<-- Customer gets updated return View(); } } public class LoadCurrentCustomer : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { const string parameterName = "Customer"; if (filterContext.ActionParameters.ContainsKey(parameterName)) { if (filterContext.HttpContext.User.Identity.IsAuthenticated) { Customer CurrentCustomer = DependencyResolverFactory .GetDefault() .Resolve<IUserSession>() .GetCurrentUser(); filterContext.ActionParameters[parameterName] = CurrentCustomer; } } base.OnActionExecuting(filterContext); } } public class UserSession : IUserSession { private readonly ICustomerRepository repository; public UserSession(ICustomerRepository customerRepository) { repository = customerRepository; } public Customer GetCurrentUser() { var identity = HttpContext.Current.User.Identity; if (!identity.IsAuthenticated) { return null; } Customer customer = repository.GetByEmailAddress(identity.Name); return customer; } } I also tried to call update on the repository like the following code shows. But this leads to an NHibernateException which says "Illegal attempt to associate a collection with two open sessions". Actually there is only one. public ActionResult Save(Customer customer) { Customer customerToUpdate = repository .GetById(customer.Id); customer.GivenName = "test"; repository.Update(customerToUpdate); return View(); } Does somebody have an idea why the customer is not updated in the first example but is updated in the second example? Why does NHibernate say that there are two open sessions?

• Atlassian Crucible very slow on large repository

  - by Mitch Lindgren

  Hi everyone, My company has been running a trial of Atlassian Crucible for some months now. For repositories where it's working properly, users have given very positive feedback about the tool. The problem I'm having is that we have several different projects, each with its own repository, and some of those repositories are very large. One repository in particular has a large number of branches and probably around 9,000 files per branch. Browsing that repository in Crucible is extremely slow. Crucible is running on a CentOS VM. The VM has 4GB of RAM, and I've set Crucible's maximum at 3GB, of which it is currently using 2GB. I've brought this up in a support ticket with Atlassian, and they suggested the following: In particular because you have a rather large SVN repository you will likely find that Fisheye will be creating a large index file on disk. To help improve performance a few things you can try are: Increasing the available memory available to Fisheye (see the document above). Migrating to an external database: confluence.atlassian.com/display/FISHEYE/Migrating+to+an+External+Database Excluding files and directories from your index that aren't needed: confluence.atlassian.com/display/FISHEYE/Allow+(Process) (Sorry for not hyperlinking; don't have the rep.) I've tried all of these things to an extent, but so far none have helped greatly. I was originally running Crucible on a Windows box with 2GB of RAM using the built in HSQL DB. Moving to MySQL on CentOS saw a performance increase for some repositories, and made Crucible much more stable, but did not seem to help much with our biggest repository. There are only so many files/branches I can exclude from indexing while maintaining the tool's usefulness. That being the case, does anyone have any tips on how to speed up Crucible on large repositories, without investing in insanely powerful hardware? Thanks! Edit: To clarify, since I didn't mention it explicitly above, I am using FishEye.

• How to set up a staging apt repository to securely manage upgrades

  - by andreash

  Hello, I would like to be able to run automatic apt-get upgrade (once per hour) on our servers (Ubuntu 10.04), so that I don't have to do it manually on all of them (about 15). However, for production machines, that's not a good idea ... So here's my idea: Set up a local repository for all 'approved' updates for critical packages. I would then push updated packages from upstream to our local repo after I tested them, and all servers could automatically (apt-cron?) upgrade from this repository. So my question is this: How do I configure apt on the clients so that they use the local repository only for all packages which exist on the local repository, and the upstream one for all other packages? Does this actually make sense? Or am I missing something? Anyways, thanks for your insight! Andreas.

• I don't get object-oriented programming

  - by Joel J. Adamson

  Note: this question is an edited excerpt from a blog posting I wrote a few months ago. After placing a link to the blog in a comment on Programmers.SE someone requested that I post a question here so that they could answer it. This posting is my most popular, as people seem to type "I don't get object-oriented programming" into Google a lot. Feel free to answer here, or in a comment at Wordpress. What is object-oriented programming? No one has given me a satisfactory answer. I feel like you will not get a good definition from someone who goes around saying “object” and “object-oriented” with his nose in the air. Nor will you get a good definition from someone who has done nothing but object-oriented programming. No one who understands both procedural and object-oriented programming has ever given me a consistent idea of what an object-oriented program actually does. Can someone please give me their ideas of the advantages of object-oriented programming?
