 You typically will change the `appsettings.json` inside the `.DbMigrator` and `.Web` projects, but it depends on your solution structure.
 
-## Change the Migrations DbContext
-
-MySQL DBMS has some slight differences than the SQL Server. Some module database mapping configuration (especially the field lengths) causes problems with MySQL. For example, some of the the [IdentityServer module](Modules/IdentityServer.md) tables has such problems and it provides an option to configure the fields based on your DBMS.
-
-The startup template contains a *YourProjectName*MigrationsDbContext which is responsible to maintain and migrate the database schema. This DbContext basically calls extension methods of the depended modules to configure their database tables.
-
-Open the *YourProjectName*MigrationsDbContext and change the `builder.ConfigureIdentityServer();` line as shown below:
-
-````csharp
-builder.ConfigureIdentityServer(options =>
-{
-    options.DatabaseProvider = EfCoreDatabaseProvider.MySql;
-});
-````
-
-Then `ConfigureIdentityServer()` method will set the field lengths to not exceed the MySQL limits. Refer to related module documentation if you have any problem while creating or executing the database migrations.
-
 ## Re-Generate the Migrations
 
 The startup template uses [Entity Framework Core's Code First Migrations](https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/). EF Core Migrations depend on the selected DBMS provider. So, changing the DBMS provider will cause the migration fails.

+# Switch to EF Core Oracle Provider
+
+This document explains how to switch to the **Oracle** database provider for **[the application startup template](Startup-Templates/Application.md)** which comes with SQL Server provider pre-configured.
+
+> This document uses a paid library of [Devart](https://www.devart.com/dotconnect/oracle/) company, because it is the only library for Oracle that supports EF Core 3.x.
+
+## Replace the Volo.Abp.EntityFrameworkCore.SqlServer Package
+
+`.EntityFrameworkCore` project in the solution depends on the [Volo.Abp.EntityFrameworkCore.SqlServer](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.SqlServer) NuGet package. Remove this package and add the same version of the [Volo.Abp.EntityFrameworkCore.Oracle.Devart](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.Oracle.Devart) package.
+
+## Replace the Module Dependency
+
+Find ***YourProjectName*EntityFrameworkCoreModule** class inside the `.EntityFrameworkCore` project, remove `typeof(AbpEntityFrameworkCoreSqlServerModule)` from the `DependsOn` attribute, add `typeof(AbpEntityFrameworkCoreOracleDevartModule)` (also replace `using Volo.Abp.EntityFrameworkCore.SqlServer;` with `using Volo.Abp.EntityFrameworkCore.Oracle.Devart;`).
+
+## UseOracle()
+
+Find `UseSqlServer()` calls in your solution, replace with `UseOracle()`. Check the following files:
+
+* *YourProjectName*EntityFrameworkCoreModule.cs inside the `.EntityFrameworkCore` project.
+* *YourProjectName*MigrationsDbContextFactory.cs inside the `.EntityFrameworkCore.DbMigrations` project.
+
+
+In the `CreateDbContext()` method of the *YourProjectName*MigrationsDbContextFactory.cs, replace the following code block
+
+```
+var builder = new DbContextOptionsBuilder<YourProjectNameMigrationsDbContext>()
+                .UseSqlServer(configuration.GetConnectionString("Default"));
+```
+
+with this one
+```
+var builder = (DbContextOptionsBuilder<YourProjectNameMigrationsDbContext>)
+	new DbContextOptionsBuilder<YourProjectNameMigrationsDbContext>().UseOracle
+	(
+		configuration.GetConnectionString("Default")
+	);
+``` 
+
+> Depending on your solution structure, you may find more code files need to be changed.
+
+## Change the Connection Strings
+
+Oracle connection strings are different than SQL Server connection strings. So, check all `appsettings.json` files in your solution and replace the connection strings inside them. See the [connectionstrings.com]( https://www.connectionstrings.com/oracle/ ) for details of Oracle connection string options.
+
+You typically will change the `appsettings.json` inside the `.DbMigrator` and `.Web` projects, but it depends on your solution structure.
+
+A sample connection string for Oracle:
+```
+Data Source=localhost;User Id=myuser;Password=mypassword;
+```
+
+## Re-Generate the Migrations
+
+The startup template uses [Entity Framework Core's Code First Migrations](https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/) by default. 
+EF Core Migrations depend on the selected DBMS provider. Changing the DBMS provider, may not work with the existing migrations.
+
+* Delete the `Migrations` folder under the `.EntityFrameworkCore.DbMigrations` project and re-build the solution.
+* Run `Add-Migration "Initial"` on the Package Manager Console window (select the `.DbMigrator`  (or `.Web`) project as the startup project in the Solution Explorer and select the `.EntityFrameworkCore.DbMigrations` project as the default project in the Package Manager Console).
+
+This will scaffold a new migration for Oracle.
+
+Run the `.DbMigrator` project to create the database, apply the changes and seed the initial data.
+
+## Run the Application
+
+It is ready. Just run the application and enjoy coding.

+## RTL Support
+
+As of v2.9 ABP has RTL support. If you are generating a new project with v2.9 and above, everything is set, you do not need to do any changes. If you are migrating your project from an earlier version, please follow the 2 steps below:
+
+#### Step 1. Create Chunks for Bootstrap LTR and RTL
+
+Find [styles configuration in angular.json](https://angular.io/guide/workspace-config#style-script-config) and make sure the chunks in your project has `bootstrap-rtl.min` and `bootstrap-ltr.min` as shown below.
+
+```json
+{
+  "projects": {
+    "MyProjectName": {
+      "architect": {
+        "build": {
+          "options": {
+            "styles": [
+              {
+                "input": "node_modules/@abp/ng.theme.shared/styles/bootstrap-rtl.min.css",
+                "inject": false,
+                "bundleName": "bootstrap-rtl.min"
+              },
+              {
+                "input": "node_modules/bootstrap/dist/css/bootstrap.min.css",
+                "inject": true,
+                "bundleName": "bootstrap-ltr.min"
+              },
+              {
+                "input": "node_modules/@fortawesome/fontawesome-free/css/all.min.css",
+                "inject": true,
+                "bundleName": "fontawesome-all.min"
+              },
+              {
+                "input": "node_modules/@fortawesome/fontawesome-free/css/v4-shims.min.css",
+                "inject": true,
+                "bundleName": "fontawesome-v4-shims.min"
+              },
+              "apps/dev-app/src/styles.scss"
+            ],
+          }
+        }
+      }
+    }
+  }
+}
+
+#### Step 2. Clear Lazy Loaded Fontawesome in AppComponent
+
+If you have created and injected chunks for Fontawesome as seen above, you no longer need the lazy loading in the `AppComponent` which was implemented before v2.9. Simply remove them. The `AppComponent` in the template of the new version looks like this:
+
+```js
+import { Component } from '@angular/core';
+
+@Component({
+  selector: 'app-root',
+  template: `
+    <abp-loader-bar></abp-loader-bar>
+    <router-outlet></router-outlet>
+  `,
+})
+export class AppComponent {}
+```
+

+## RTL支持
+
+从v2.9开始,ABP支持RTL. 如果使用v2.9及更高版本生成新项目,你无需进行任何更改. 如果要从早期版本迁移项目,请按照以下2个步骤操作:
+
+#### 步骤 1. 为 Bootstrap LRT和RTL创建Chunks
+
+在[angular.json中找到样式配置](https://angular.io/guide/workspace-config#style-script-config)确保项目中的chunks含有 `bootstrap-rtl.min` 和 `bootstrap-ltr.min`:
+
+```json

+                "input": "node_modules/bootstrap/dist/css/bootstrap.min.css",
+                "inject": true,
+                "bundleName": "bootstrap-ltr.min"
+              },
+              {
+                "input": "node_modules/@fortawesome/fontawesome-free/css/all.min.css",
+                "inject": true,
+                "bundleName": "fontawesome-all.min"
+              },

+                "inject": true,
+                "bundleName": "fontawesome-v4-shims.min"
+              },

+            ],
+          }
+        }
+      }
+    }
+  }
+}
+
+#### 步骤 2. 清除AppComponent中延迟加载的Fontawesome
+
+如果你如上所述为Fontawesome创建并且注入了chunks,就不再需要v2.9版本之前的实现的 `AppComponent` 延迟加载. 删除它们即可,新版的 `AppComponent` 如下所示:
+
+```js
+import { Component } from '@angular/core';
+
+@Component({
+  selector: 'app-root',
+  template: `
+    <abp-loader-bar></abp-loader-bar>
+    <router-outlet></router-outlet>
+  `,
+})
+export class AppComponent {}
+```
