    You can use AbpAuditLogging connection string for separate audit logging in appsettings like:

    "ConnectionStrings": {
  "Default": "Server=localhost;Database=ApplicationDb;Trusted_Connection=True;",
  "AbpAuditLogging": "Server=localhost;Database=AuditLoggingDb;Trusted_Connection=True;"
}

    Thanks gterdem. I am using Window10 and VS 2022. After making connection string changes in appsettings in host, identity and DBMigrator project, i run the DBMigrator project but Audit tables not created in new audit db.

    What step i should take to create Audit feature realted tables in new DB.

    Could not understand where exactly i have to make changes. As it seems i have seperate set of files.

    In entity framework core i have 4 files: EzpandCCDbContext EzpandCCDbContextModelCreatingExtensions EzpandCCEfCoreEntityExtensionMappings EzpandCCEntityFrameworkCoreModule

    in sample 7 files provided BookStoreDbContext.cs BookStoreDbContextFactory.cs BookStoreEfCoreEntityExtensionMappings.cs BookStoreEntityFrameworkCoreModule.cs BookStoreSecondDbContext.cs BookStoreSecondDbContextFactory.cs EntityFrameworkCoreBookStoreDbSchemaMigrator.cs

    *DbContextFactory, EntityFrameworkCoreBookStoreDbSchemaMigrator is surely missing. Do i have to create them also. If yes can you confrim me all Audit related tables exist so that i can keep them in secodDbContext and will emove from *DBContext. Please remember i am using 4.2.2

    Hello, I have explained how to do this step by step below. You can do it this way too. If you have any questions, please don't hesitate to ask.

    • Create EzpandCCSecondDbContext.cs in EzpandCC.EntityFrameworkCore.DbMigrations/EntityFrameworkCore/

    • Create EzpandCCSecondDbContextFactory.cs in EzpandCC.EntityFrameworkCore.DbMigrations/EntityFrameworkCore/

    • Remove below line from EzpandCCMigrationsDbContext in EzpandCC.EntityFrameworkCore.DbMigrations/EntityFrameworkCore/

    builder.ConfigureAuditLogging();

    • Add below lines to MigrateAsync method in EntityFrameworkCoreEzpandCCDbSchemaMigrator class in EzpandCC.EntityFrameworkCore.DbMigrations/EntityFrameworkCore/
    await _serviceProvider
                .GetRequiredService<EzpandCCSecondDbContext>()
                .Database
                .MigrateAsync();
    • Add below line to ConfigureServices metod in EzpandCCEntityFrameworkCoreDbMigrationsModule class in EzpandCC.EntityFrameworkCore.DbMigrations/EntityFrameworkCore/

    context.Services.AddAbpDbContext<EzpandCCSecondDbContext>();

    • Add the following connection string under Default for all appsettings.json.

    "AbpAuditLogging": "Server=(LocalDb)\\MSSQLLocalDB;Database=EzpandCC;Trusted_Connection=True"

    • Run below commands in EzpandCC.EntityFrameworkCore.DbMigrations/

    dotnet ef migrations add "Initial" --context EzpandCCMigrationsDbContext dotnet ef migrations add "Initial" --context EzpandCCSecondDbContext

    • Finally, run the EzpandCC.DbMigrator project.

    Run below commands in EzpandCC.EntityFrameworkCore.DbMigrations/

    1. dotnet ef migrations add "Initial" --context EzpandCCMigrationsDbContext

    2. dotnet ef migrations add "Initial" --context EzpandCCSecondDbContext

    These two commands need to be run sequentially, not together.

    Additional Information

    If you changed the name of the second DbContext you created, if EzpandCCSecondDbContext is different from this name, it should change accordingly in the command.

    For example: My second DB context name is MyNewDbContext and so I have to write the following code.

    dotnet ef migrations add "Initial" --context MyNewDbContext
