Oracle 数据库（包括 19c）本身并不支持原生的 BOOLEAN 类型，EF Core 在生成迁移脚本时会直接映射为 BOOLEAN，导致如你截图所示的错误。你当前用的 .HasConversion<int>() 方式（将 bool 转为 int 0/1）是主流且推荐的做法。

ABP 官方和 EF Core 社区都没有更“自动化”的通用方案，建议如下：

1. 保持你现在的写法：

   builder.Entity<BackgroundJobRecord>()
       .Property(u => u.IsAbandoned)
       .HasConversion<int>(); // bool 映射为 int (0/1)
   

   这样迁移脚本会生成 NUMBER(1) 字段，兼容 Oracle。

2. 如果有多个 bool 字段，可以写一个扩展方法批量处理，或在基类/通用配置中统一加上。

3. 迁移脚本生成后，务必检查是否有 BOOLEAN 类型，手动改为 NUMBER(1) 或 tinyint。

4. 参考官方文档说明：

   • https://abp.io/docs/latest/framework/data/entity-framework-core/oracle-devart

结论：EF Core + Oracle 下，bool 字段只能用 .HasConversion<int>() 或手动映射为 NUMBER(1)。没有更自动的通用方案，这是 Oracle 的限制。

To successfully roll back from ABP 9 to ABP 8, you must ensure that both your application code and your database schema are fully reverted to their ABP 8 state. The error you are seeing indicates a schema mismatch: your ABP 8.2.3 code expects columns like IsDeleted, CreationTime, etc., but your database is missing them—likely because the ABP 9 migration dropped or altered these columns.

Here’s how to resolve this:

1. Restore the Database:

   • You must restore the database backup that was taken before the ABP 9 upgrade. This ensures the schema matches what ABP 8 expects.
   • If you already restored the backup, double-check that the restore completed successfully and that you are connecting to the correct database instance.

2. Clear All Caches:

   • You already restarted the Redis cache, which is good.
   • Also clear any other distributed caches or in-memory caches that might be holding old schema or metadata.

3. Verify Connection Strings:

   • Ensure your ABP 8.2.3 application is pointing to the restored (pre-ABP 9) database, not a database that was migrated to ABP 9.

4. Check for Shadow Migrations:

   • If any migrations were applied after the ABP 9 upgrade, make sure those are not present in your database.

5. Rebuild and Redeploy:

   • Rebuild your ABP 8.2.3 solution and redeploy all services to ensure no ABP 9 binaries or configuration remain.

6. Troubleshooting:

   • If the error persists, use SQL Server Management Studio (or your DB tool) to inspect the relevant tables (such as OpenIddict tables) and confirm that all columns expected by ABP 8 are present.
   • If columns are missing, the database restore may not have completed or the wrong backup was used.

If you follow these steps and ensure both code and database are in sync for ABP 8, the error should be resolved.

• In ABP, when you define permissions with MultiTenancySides, permissions marked as Host are only available to host users, and Tenant for tenant users. Permissions with Both are available to both.

• If your menu's requiredPolicy is set to the "application area" permission (MultiTenancySides = Both), then both host and tenant users can be granted this permission. If a tenant user is seeing the menu item even when their role does not have the permission, it usually means:

  • The permission is being granted by default to tenant roles (e.g., tenant admin), or
  • The permission check logic is not correctly evaluating the user's granted permissions.

• By default, when you add a new permission, it is not automatically granted to existing tenant roles unless you explicitly seed it. However, if your permission tree is structured so that a parent permission is granted, all child permissions may be considered granted unless you override this behavior.

• For your scenario, ensure:

  1. The "application area" permission is not granted to the tenant user's role.
  2. The permission check in your menu (requiredPolicy) is checking for the correct permission name.
  3. You are not programmatically granting the permission elsewhere (e.g., in a migration or seeding service).

• To debug:

  • Check the AbpPermissionGrants table for the tenant and user/role in question to see if the permission is granted.
  • Use the Permission Management UI or API to verify the effective permissions for the user/role.
  • If you are using hierarchical permissions, ensure that granting a parent does not implicitly grant children unless intended.

• If you want tenant users to have read-only access only when explicitly granted, make sure the "application area" permission is not granted by default to tenant roles, and that your menu checks for this permission.

• If you have recently added new permissions, remember that existing tenant roles will not have them granted automatically. You may need to update your seeding logic or manually assign them.

• To enable client-side validation in an ABP MVC Core Razor Pages project, you must ensure that the required validation scripts are included in your layout. ABP's default layouts include these scripts, but if you use a custom layout, you need to add them manually.

• Add the following lines before the closing </body> tag in your custom layout to enable client-side validation:

@section Scripts
{
    <partial name="_ValidationScriptsPartial" />
}

Or, if your layout does not support sections, add directly:

<partial name="_ValidationScriptsPartial" />

• Make sure your form includes the correct asp-validation-summary and asp-validation-for tags, which you already have.

• Also, ensure that jQuery and the validation libraries are loaded. The _ValidationScriptsPartial partial includes these by default.

• If you use a custom error message key (e.g., "Validation:EmailRequired"), ensure that your localization resources contain the corresponding translations.

• Example minimal layout addition:

<body>
    @RenderBody()
    <partial name="_ValidationScriptsPartial" />
</body>

• After these changes, client-side validation should work as expected for your form.

To implement a notification widget in ABP Framework that displays real-time popups (such as in the top right corner), you can leverage SignalR for real-time messaging and ABP’s extensibility for UI integration. Here’s a recommended approach:

1. Use SignalR for Real-Time Notifications

• ABP supports SignalR integration, allowing you to push notifications from the backend to the frontend in real time.
• You can create a SignalR hub for notifications and send messages to connected clients.

2. Implement the Notification Widget

• Add a notification bell icon to your layout (toolbar or header).
• When a notification is received (via SignalR), display a popup (toast) in the desired position (e.g., top right).
• Optionally, clicking the bell can open a notification panel or list.

3. Example Implementation Steps

• Backend: Create a SignalR hub and notification service.
• Frontend: Add SignalR client code, handle incoming messages, and show popups using your preferred UI library (e.g., toastr, SweetAlert, or a custom component).

Example resources:

• ABP Community article with a full SignalR notification example (backend and frontend):
  https://abp.io/community/articles/tsp2uqd3
• ABP Blazor notification toolbar integration (for bell icon and popup):
  https://abp.io/support/questions/6728
• ABP Studio’s notification UI for design inspiration:
  https://abp.io/docs/latest/studio/overview

This approach is modular and works for MVC, Angular, and Blazor UIs. You can customize the notification appearance and behavior as needed.

• When you change the permission structure in a microservice, the new permissions are registered in the database only when the microservice is restarted. However, the UI may not reflect the new structure immediately due to caching or because the admin role does not automatically get new permissions.

• Steps to ensure the UI reflects your new permission structure:

  1. Restart the microservice where you updated the permission definitions. This ensures the new permissions are registered in the permission definition tables.
  2. Restart the Administration service. Only the Administration microservice seeds permissions to the admin role. If you add new permissions, the admin role will not have them by default until the Administration service is restarted, or you grant them manually.
  3. Clear the browser cache and refresh the UI. Sometimes, the UI may cache old permission data.
  4. Manually grant new permissions to the admin role if needed, using the Permission Management dialog.

• If you want new permissions to be automatically granted to the admin role, implement a data seeder using the IPermissionDataSeeder service in your microservice.

• If you still do not see the new structure, ensure that your Angular UI is not using a cached API response and that the backend API is returning the updated permission structure.

To upgrade your ABP solution from 8.3.0 to 9.2.0, you need to follow the migration steps for each major version increment. The ABP migration process does not provide a single SQL migration file that covers both host and tenant databases for all scenarios, especially when using separate schemas for tenants. Instead, you should:

1. Review and apply the breaking changes and migration steps in the official migration guides for each version jump (8.x to 9.0, then 9.0 to 9.2).
2. Update your Entity Framework Core migrations in your solution to reflect any changes in the ABP modules and your own entities.
3. Run the generated migrations for both the host and all tenant schemas.

Recommended Steps:

1. Read and follow the official migration guide for ABP 9.0:

   • ABP Version 9.0 Migration Guide

2. After updating your codebase and dependencies, use the standard EF Core migration workflow:

   • Run Add-Migration (or dotnet ef migrations add) to generate a migration that includes all changes from 8.3.0 to 9.2.0.
   • Apply the migration to the host database.
   • Apply the same migration to each tenant schema (since you use separate schemas).

3. If you use ABP's SaaS module with separate schemas, ensure your migration logic iterates over all tenant schemas and applies the migration to each.

Note: There is no official, pre-generated "single migration file" provided by ABP for all host and tenant upgrades. The migration is generated based on your current database state and code changes.

Summary:

• Update your solution and dependencies as per the migration guide.
• Generate a new EF Core migration after all code changes.
• Apply the migration to both host and tenant schemas.

Based on your screenshots and description, the main issue is that your Angular application is trying to call the OpenID Connect configuration and application configuration endpoints on the wrong port (44374), even though your backend is running on port 7511. This is a configuration issue, not related to the separation of AuthServer (since you are using a non-tiered template).

Here’s how to resolve it:

1. Check Angular Environment Configuration

   • In your environment.prod.ts (or the environment file used for production), ensure the oAuthConfig.issuer, redirectUri, and API URLs point to the correct backend port (7511), not 44374.
   • Example:

     export const environment = {
       production: true,
       application: {
         baseUrl: 'https://localhost:7511',
         name: 'YourAppName',
       },
       oAuthConfig: {
         issuer: 'https://localhost:7511',
         redirectUri: 'https://localhost:7511',
         clientId: 'YourAppName_App',
         responseType: 'code',
         scope: 'offline_access openid profile email phone YourAppName',
       },
       apis: {
         default: {
           url: 'https://localhost:7511',
           rootNamespace: 'YourAppName',
         },
       },
     };
     

   • Rebuild and redeploy your Angular app after making these changes.

2. Check appsettings.json in Backend

   • Make sure the App:SelfUrl, App:AngularUrl, and AuthServer:Authority are all set to https://localhost:7511 (or your deployed domain).
   • Example:

     "App": {
       "SelfUrl": "https://localhost:7511",
       "AngularUrl": "https://localhost:7511",
       "CorsOrigins": "https://localhost:7511"
     },
     "AuthServer": {
       "Authority": "https://localhost:7511",
       "RequireHttpsMetadata": "false"
     }
     

3. Clear Browser Cache

   • After updating and redeploying, clear your browser cache or use an incognito window to avoid cached configuration issues.

4. No Need for AuthServer Separation

   • In a non-tiered template, the same backend serves both API and authentication endpoints. You do not need a separate AuthServer.

5. IIS Rewrite Rules

   • Ensure your IIS rewrite rules (if any) do not redirect or rewrite requests to the wrong port.

6. Verify Application Configuration

   • After deployment, open the browser console and network tab to confirm that all requests are being made to the correct port/domain.

By ensuring all URLs in both Angular and backend configurations match your deployed backend port/domain, the redirection and CORS issues should be resolved.

• Circular dependency errors like the one you encountered are typically caused by changes in service registrations or module dependencies that introduce a loop in the dependency graph. Since your solution works on 9.1.0 but fails on 9.2.0, it is likely related to breaking changes or new features introduced in ABP 9.2.0.

To debug and resolve this issue:

1. Check the ABP 9.2 Migration Guide
   Review the official migration guide for ABP 9.2.0 to identify any breaking changes or required code updates:

   • https://abp.io/docs/9.2/release-info/migration-guides/abp-9-2

2. Review Recent Module/Service Changes

   • Examine your custom modules and services for new or changed dependencies that could introduce a circular reference.
   • Pay special attention to constructor injection and module dependencies ([DependsOn] attributes).

3. Isolate the Problem

   • Temporarily comment out or remove recently added services or modules, then re-add them one by one to identify the source of the circular dependency.

4. Enable Detailed Autofac Diagnostics

   • Autofac (the DI container used by ABP) can provide more detailed diagnostics. You can enable diagnostic output to help pinpoint the exact services involved in the cycle.

5. Compare with a Fresh 9.2.0 Solution

   • Generate a new ABP 9.2.0 solution and compare its module/service registrations with your upgraded solution. This can help spot differences or missing updates.

6. Check for Known Issues

   • Review the ABP 9.2.0 release notes and community articles for any known issues or patterns related to circular dependencies:
     • https://abp.io/community/articles/jpq072nh

7. Common Pitfalls

   • Avoid injecting services into each other in a way that forms a loop (e.g., ServiceA → ServiceB → ServiceA).
   • Ensure that your module dependencies do not form a cycle.

If you identify the specific services or modules involved in the cycle, refactor to remove the circular reference (e.g., use eventing, factories, or lazy injection).

To resolve the issues with tenant impersonation and tenant switching (400/403 errors, "tenant does not exist", "no user with username: admin"), please check the following:

1. Tenant Existence and Name

   • Ensure the tenant name ("alpha" in your screenshots) is correct and exists in the database.
   • Tenant names are case-sensitive and must match exactly.

2. Tenant Admin User

   • Each tenant must have an admin user. By default, the username is "admin" unless changed during tenant creation.
   • If you get "There is no user with username: admin!", verify that the "admin" user exists under the "alpha" tenant. You can check this in the SaaS > Tenants > Users section.

3. Cache Consistency

   • In tiered/separated deployments, cache key mismatches can cause tenant/user not found errors.
   • Ensure all your services (AuthServer, HttpApi.Host, etc.) use the same cache configuration and prefix. If you recently upgraded or changed configuration, clear all distributed caches (e.g., Redis).

4. Database Consistency

   • Confirm that the tenant and its admin user exist in the correct tables (SaasTenants, AbpTenants, AbpUsers) and are not soft-deleted.

5. Migration Issues

   • If you recently upgraded ABP or migrated from community to commercial, follow the official migration guide and ensure all migrations are applied:
     • https://docs.abp.io/en/abp/latest/Migration-Guides/Abp-8_1

6. Impersonation Permissions

   • Make sure the host user has the required permissions for tenant/user impersonation:
     • https://abp.io/docs/latest/modules/account/impersonation

7. Restart and Clear Cookies

   • After making changes, restart all services and clear browser cookies to avoid stale session/cookie issues.

If you follow these steps and the issue persists, double-check the logs for cache or database inconsistencies, and ensure the tenant and user data are present and correct.
