Database Requirement 5 - SQL Common Language Runtime (CLR) Strict Security for SQL Server 2017 or newer

All database intensive operations (not just database maintenance, but also trace lineage, delete models, etc.) are implemented in SQL Server by stored procedures written in C# compiled/delivered in a stored procedure assembly called MIRRepo which has been signed that will be created with permission set SAFE.

If you are using SQL server 2017 or newer, then CLR Strict Security is enabled by default. Therefore, the certificate used to sign the stored procedure assembly must be imported in the database and granted the UNSAFE assembly permission (See Microsoft SQL Docs on CLR strict security) using the following commands:

CREATE CERTIFICATE MIRRepoCert FROM BINARY = 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;

CREATE LOGIN MIRRepoCertLogin FROM CERTIFICATE MIRRepoCert;

GRANT UNSAFE ASSEMBLY TO MIRRepoCertLogin;

Alternatively, you can disable the SQL Server CLR Strict Security as follows:

EXEC sp_configure 'show advanced options', 1;
‎RECONFIGURE;
‎EXEC sp_configure 'clr strict security', 0;
‎RECONFIGURE;
‎EXEC sp_configure 'show advanced options', 0;
‎RECONFIGURE;
