Offline Database.
Offline Database.
Hi, I'm helping you with setting up Comarch ERP Optima. You mentioned needing a Microsoft SQL Server database on a single computer. You don’t need another machine—just ensure the local setup works for your app. You can use a USB drive to move files between devices if needed. Since you're new to SQL Server, it’s fine to explore it through simple tools like Filezilla for basic connectivity. The process involves installing the database on your PC and configuring it to communicate with the app. Let me know if you need step-by-step guidance!
Obtain a legitimate SQL Server installer and run the installation on your device. There appears to be a publicly accessible free option available.
You can easily download the free version from the link provided: https://www.microsoft.com/en-us/sql-serv...-downloads. Look for "Express" and select "SQL Server 2019 Express." This edition is perfect for both development and production, supporting desktop, web, and small server projects. A database server can be hosted locally on the same PC as you would a remote one.
Sure, please let me know your specific needs. I’ll help you pick the right database type based on what you’re working with.
Hello, your question is clear. You should check if any adjustments are needed since you're not expecting the computer to stay on continuously. You likely won’t need to connect every time unless you want a manual start, and whether to run the server depends on your setup.
The database needs to be accessible whenever the app tries to link to it. Placing them together on the same machine works fine. By default, SQL Server runs as a Windows service, ensuring it's always active, allowing the application to connect smoothly.
You're facing the same issue where the connection fails with "sa user login failed." Let's go through the steps in simple terms.
1. **Check User Credentials**
- Ensure your username and password are correct.
- Verify that the database server is running and accessible.
2. **Verify Database Connection Settings**
- Open SQL Server Configuration Manager.
- Go to **SQL Server Network Configuration**.
- Make sure the connection string matches your setup (server name, database name, authentication type).
3. **Test Connection Manually**
- Use a tool like SSMS or an online SQL client.
- Try connecting with the correct credentials.
4. **Check Firewall & Security Settings**
- Ensure port 1433 (or your server's port) is open.
- Confirm no firewall blocks the connection.
5. **Restart Services**
- Restart the SQL Server service and any related services.
6. **Update Drivers & Software**
- Ensure your drivers are up to date.
- Reinstall or update SSMS if needed.
7. **Review Logs**
- Check SQL Server logs for more details about the failure.
If you're still stuck, double-check that you've added users in the server and that their permissions are set correctly. Let me know what you find!
It mentions this in the context of ERP or SSMS. The "sa" account is the default SQL Server user, similar to root on Linux or Administrator on Windows—it has full access. The warning indicates a login failure, likely due to a missing or incorrect password. The sa user should exist by default but is usually disabled for security. You may need to enable it, create a password, and follow the provided guide: https://community.boschsecurity.com/t5/S...ta-p/10193. This seems relevant for MSSQL 2019; if you used Windows Authentication in SSMS, consider switching to ERP or enabling the sa user, setting a password, and then configuring it in ERP.
The ERP Optima site states compatibility with MSSQL 2012 or later, but my system is running Windows 7. I have two connection methods: NT Authentication and standard user login, neither of which works. Changes to the SA user configuration are lost after closing SQL Server Management Studio. I can log in as both the Sa user and Windows authentication in SQL Server Management Studio without issues.
