    hi

    No such host is known.

    This is like a problem of connecting strings.

    The target machine actively refused it.'

    Can you check the target machine logs?

    You can also test your connection string in the plain EF Core app.

    I can test the connecting string in my docker environment. Can you share more info? liming.ma@volosoft.com

    1. "Default": "Data Source=localhost:1521/ORCLPDB;User Id=testadmin1;Password=********"

    2. "Default": "Data Source=ORCLPDB;User Id=testadmin1;Password=*******;"

    3. "Default": "User Id=testadmin1;Password=*******;Data Source=(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)))(CONNECT_DATA =(SERVICE_NAME = ORCLPDB)))"

    3rd one is working fine in my sample app (Without using ABP)

    hi

    I think the problem is about the format of connecting strings.

    Are you using the Devart.Data.Oracle.EFCore or Oracle.EntityFrameworkCore

    I am not using any thing. Just using the project created from ABP Suite with Oracle as DB. So what ever default is created by ABP Suite , i am using the same.

    I guess you had selected the Oracle as db.

    The format is User Id=<USER ID>;Password=<PASSWORD>;Data Source=<DATA SOURCE>;

    Can I check it remotely?
