Today, we’re diving into a common yet perplexing issue that can stump even the most experienced SQL Server professionals – the infamous Msg 10314 error. This error occurs when the Microsoft .NET Framework encounters problems loading an assembly in SQL Server, often leading to a head-scratching situation. With this guide, you’ll learn how to navigate and resolve this issue efficiently.
Understanding the Error
First, let’s break down the error message:
Msg 10314, Level 16, State 11, Line 1
An error occurred in the Microsoft .NET Framework while trying to load assembly id 65563. The server may be running out of resources, or the assembly may not be trusted...
System.IO.FileLoadException: Could not load file or assembly 'managedcodeandsqlserver, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'...
This message typically indicates two potential issues:
- Resource Limitation: The server might be running low on resources.
- Trust Issues with the Assembly: SQL Server may not trust the assembly.
Step-by-Step Resolution
1. Check Server Resources
Ensure your SQL Server has sufficient memory and CPU resources. You can monitor this via SQL Server Management Studio (SSMS) or performance monitoring tools.
2. Verify Assembly Trustworthiness
SQL Server needs to trust any assembly running within its environment. Here’s how you can check and modify this setting:
Check Trustworthiness of the Database:
SELECT name, is_trustworthy_on FROM sys.databases WHERE name = 'YourDatabaseName';Replace YourDatabaseName with the name of your database.
Enable Trustworthiness (If Required):
ALTER DATABASE [YourDatabaseName] SET TRUSTWORTHY ON;Remember, changing this setting should be done with an understanding of its security implications.
3. Consider CLR Integration Settings
Ensure CLR integration is enabled in SQL Server:
sp_configure 'clr enabled', 1;
RECONFIGURE;
4. Examine Assembly Details
Review the specific assembly causing the issue:
SELECT * FROM sys.assemblies WHERE name = 'AssemblyName';
Replace AssemblyName with the name of your problematic assembly.
5. Address Security Policies
You might need to adjust its permissions if your assembly requires external resources or makes network calls.
Advanced Tips
- Extracting and Examining the Assembly: If you have the original source code, ensure it’s compiled correctly and targeted to the appropriate .NET Framework version compatible with your SQL Server.
- Using Certificates for Security: Consider signing your assemblies with certificates for a more secure approach.
Final Thoughts
Resolving the Msg 10314 error in SQL Server can be challenging, but with the right approach, it’s certainly manageable. Always back up your database before making significant changes, and consult with a database administrator if unsure about any steps.
