How To Determine Oracle Version Installed Meaning In UrduEntity Framework 6, database- first with Oracle. I spent a lot of time trying to find out how to implement Entity Framework 6 database- first scenario with Oracle database. It’s not as straightforward as you might think. I searched various websites and found only confusing information. Finally I got it working, therefore I can confirm that EF6 database- first works with Oracle databases. First, let me clarify my environment. I have Visual Studio 2. Save time and reduce risks with Toad for Oracle, the leading database development and optimization software, as ranked by IDC*. With Toad, you’ll improve project. R01 11 R02 8 R03 12 R04 9 SYSTEM 4. You have room for each to grow by 20 more extents each. Is there a problem? Should you take any action No there is not a problem. NET Framework 4. 5. Secondly, a word about my goal. I wanted to create a MVC5 website that connects to existing Oracle database. So, here is how I did it. Setup Oracle Developer Tools. First I had to install Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio. Yep, long name. You can get it from Oracle web site (you’ll have to register). Make sure to take ODAC 1. Release 3 as previous versions don’t support Entity Framework 6. You will get it in a form of zip file. Next extract it and run setup. Standard installation worked for me – just click Next couple of times and Install. If you want to alter the installation, make sure you: Note Software location – the default is C: \app\client\USERNAME\product\1. A new MVC5 project has already reference to EF6, so there was nothing to do. But if you have different project you might have to install Entity Framework 6 manually. ![]() The easiest way is to use Nu. Get packages: Nu. Get manager is included in VS 2. VS 2. 01. 0 you will have to install it. Open VS and click Tools menu, then Extensions and Updates. Click Online on the left hand panel, then type Nu. Get in search text box on the right side. It should find Nu. Get Package Manager – click on it and press Download button. Visual Studio restart will be required. Next, open you project, right click it and choose Manage Nu.
Get Packages from context menu. Click Online on the left side, then type Entity in search box. Click Entity. Framework and press Install. Reference Oracle libraries. To leverage Entity Framework capabilities you have to add reference to Oracle Data Access library. Right click on References, then Add reference. If you don’t do it you will see following error when attempting to generate model from database. I lost a lot of time trying to resolve it . Welcome to Toad for Oracle. Toad for Oracle provides an efficient and accurate way for database professionals of all skill and experience levels to perform their jobs. You can check if it’s needed in your case.< configuration>. Sections>. < section name=. Well done! Summary. Configuring Entity Framework 6 to work with Oracle database in database- first scenario isn’t as easy as one would expect. Fortunately it’s doable. I also tried more elegant solution – to use ODAC Nu. Get package. But lost a lot of time and finally couldn’t make it work. Then found following comment on Oracle web site – meaning ODAC Release 3 which has EF6 support is not uploaded as Nu. Get package yet. Note: Nu. Get installation is not currently available, but will be available shortly. Issue with adding new Oracle connection. I had a strange issue when I tried to setup database connection. I clicked New connection and couldn’t find my database in Data source list, so I clicked Advanced button. I filled following fields and clicked OK. Security / User Id. Security / Password. Source / Data Source. Then clicked Test Connection and was again surprised – it couldn’t find my instance. I checked some SQL client and my database was working well. I did some searching and found following way to overcome this impairment. Run tnsping INSTANCE. Later I updated data source in web. INSTANCE. WORLD back to only INSTANCE) and application worked fine. How to Write Doc Comments for the Javadoc Tool. Javadoc Home Page. This document describes the style guide, tag and image conventions we use in documentation comments for Java programs written at Java Software, Oracle. It does not rehash related material covered elsewhere: Contents. Introduction. Principles. At Java Software, we have several guidelines that might make our documentation comments different than those of third party developers. Our documentation comments define the official Java Platform API Specification. To this end, our target audience is those who write Java compatibility tests, or conform or re- implement the Java platform, in addition to developers. We spend time and effort focused on specifying boundary conditions, argument ranges and corner cases rather than defining common programming terms, writing conceptual overviews, and including examples for developers. Thus, there are commonly two different ways to write doc comments - - as API specifications, or as programming guide documentation. These two targets are described in the following sections. A staff with generous resources can afford to blend both into the same documentation (properly . This is why developers often need to turn to other documents, such as Java SE Technical Documentation and The Java Tutorials for programming guides. Writing API Specifications. Ideally, the Java API Specification comprises all assertions required to do a clean- room implementation of the Java Platform for . This may include assertions in the doc comments plus those in any architectural and functional specifications (usually written in Frame. Maker) or in any other document. This definition is a lofty goal and there is some practical limitation to how fully we can specify the API. The following are guiding principles we try to follow: The Java Platform API Specification is defined by the documentation comments in the source code and any documents marked as specifications reachable from those comments. Notice that the specification does not need to be entirely contained in doc comments. In particular, specifications that are lengthy are sometimes best formatted in a separate file and linked to from a doc comment. The Java Platform API Specification is a contract between callers and implementations. The Specification describes all aspects of the behavior of each method on which a caller can rely. It does not describe implementation details, such as whether the method is native or synchronized. The specification should describe (textually) the thread- safety guarantees provided by a given object. In the absence of explicit indication to the contrary, all objects are assumed to be . It is recognized that current specifications don't always live up to this ideal. Unless otherwise noted, the Java API Specification assertions need to be implementation- independent. Exceptions must be set apart and prominently marked as such. We have guidelines for how to prominently document implementation differences. The Java API Specification should contain assertions sufficient to enable Software Quality Assurance to write complete Java Compatibility Kit (JCK) tests. This means that the doc comments must satisfy the needs of the conformance testing by SQA. The comments should not document bugs or how an implementation that is currently out of spec happens to work. Writing Programming Guide Documentation. What separates API specifications from a programming guide are examples, definitions of common programming terms, certain conceptual overviews (such as metaphors), and descriptions of implementation bugs and workarounds. There is no dispute that these contribute to a developer's understanding and help a developer write reliable applications more quickly. However, because these do not contain API . You can include any or all of this information in documentation comments (and can include custom tags, handled by a custom doclet, to facilitate it). At Java Software, we consciously do not include this level of documentation in doc comments, and instead include either links to this information (links to the Java Tutorial and list of changes) or include this information in the same documentation download bundle as the API spec - - the JDK documentation bundle includes the API specs as well as demos, examples, and programming guides. It's useful to go into further detail about how to document bugs and workarounds. There is sometimes a discrepancy between how code should work and how it actually works. This can take two different forms: API spec bugs and code bugs. It's useful to decide up front whether you want to document these in the doc comments. At Java Software we have decided to document both of these outside of doc comments, though we do make exceptions. API spec bugs are bugs that are present in the method declaration or in the doc comment that affects the syntax or semantics. An example of such a spec bug is a method that is specified to throw a Null. Pointer. Exception when null is passed in, but null is actually a useful parameter that should be accepted (and was even implemented that way). If a decision is made to correct the API specification, it would be useful to state that either in the API specification itself, or in a list of changes to the spec, or both. Documenting an API difference like this in a doc comment, along with its workaround, alerts a developer to the change where they are most likely to see it. Note that an API specification with this correction would still maintain its implementation- independence. Code bugs are bugs in the implementation rather than in the API specification. Code bugs and their workarounds are often likewise distributed separately in a bug report. However, if the Javadoc tool is being used to generate documentation for a particular implementation, it would be quite useful to include this information in the doc comments, suitably separated as a note or by a custom tag (say @bug). Who Owns and Edits the Doc Comments. The doc comments for the Java platform API specification is owned programmers. However, they are edited by both programmers and writers. It is a basic premise that writers and programmers honor each other's capabilities and both contribute to the best doc comments possible. Often it is a matter of negotiation to determine who writes which parts of the documentation, based on knowledge, time, resources, interest, API complexity, and on the state of the implementation itself. But the final comments must be approved by the responsible engineer. Ideally, the person designing the API would write the API specification in skeleton source files, with only declarations and doc comments, filling in the implementation only to satisfy the written API contract. The purpose of an API writer is to relieve the designer from some of this work. In this case, the API designer would write the initial doc comments using sparse language, and then the writer would review the comments, refine the content, and add tags. If the doc comments are an API specification for re- implementors, and not simply a guide for developers, they should be written either by the programmer who designed and implemented the API, or by a API writer who is or has become a subject matter expert. If the implementation is written to spec but the doc comments are unfinished, a writer can complete the doc comments by inspecting the source code or writing programs that test the API. A writer might inspect or test for exceptions thrown, parameter boundary conditions, and for acceptance of null arguments. However, a much more difficult situation arises if the implementation is not written to spec. Then a writer can proceed to write an API specification only if they either know the intent of the designer (either through design meetings or through a separately- written design specification) or have ready access to the designer with their questions. Thus, it may be more difficult for a writer to write the documentation for interfaces and abstract classes that have no implementors. With that in mind, these guidelines are intended to describe the finished documentation comments. They are intended as suggestions rather than requirements to be slavishly followed if they seem overly burdensome, or if creative alternatives can be found. When a complex system such as Java (which contains about 6. This may be due to the differing requirements of those packages, or because of resource constraints. Terminology. API documentation (API docs) or API specifications (API specs) On- line or hardcopy descriptions of the API, intended primarily for programmers writing in Java. These can be generated using the Javadoc tool or created some other way. An API specification is a particular kind of API document, as described above. An example of an API specification is the on- line Java Platform, Standard Edition 7 API Specification. Documentation comments (doc comments) The special comments in the Java source code that are delimited by the /** .. These comments are processed by the Javadoc tool to generate the API docs. It is made up of two parts - - a description followed by block tags. In this example, the block tags are @param, @return, and @see. The name. * argument is a specifier that is relative to the url argument. When this applet attempts to draw the image on. The graphics primitives. This inline tag can be used anywhere that a comment can be written, such as in the text following block tags. If you have more than one paragraph in the doc comment, separate the paragraphs with a < p> paragraph tag, as shown. Insert a blank comment line between the description and the list of tags, as shown. The first line that begins with an . There is only one description block per doc comment; you cannot continue the description following block tags.
