Fix Unable to Load SQL Resource Error

Are you facing an issue while loading SQL resources? Didn’t know how to fix this issue. We will provide the entire information about the SQL resource database and why the unable to load SQL resource problem arises. You will multiple methods to resolve this SQL resource inaccessibility.

Microsoft SQL Server 2005 added a new system database called the Resource database. This is a read-only system database that is hidden from users.

Database Admins should backup the Resource Database, as well as other System Databases, in SQL Server. Users should know the location of all systems and user databases for SQL Disaster Recovery.

What is a Resource Database?

The resource database is a read-only system database that is hidden from its users. System objects aka sys.objects are physically stored in Resource Databases. It appears logically in each database’s SYS schema. The SQL resource database can only store system objects and cannot hold user data or metadata. The resource database is made up of two files: mssqlsystemresource.mdf and mssqlsystemresource.ldf. The most essential thing to remember is that the ID of the resource database is always 32767. From SQL Server 2005 to SQL Server 2014, the ID value of the resource database has stayed the same.

What is the Importance of Resource Database?

The Resource Database simplifies and accelerates the process of updating SQL Server to a new version. Previously, upgrading to a new version of SQL Server required the deletion and creation of system objects. However, the resource database comprises all system objects, upgrading can now be done by simply moving the resource database files that is – (mssqlsystemresource.mdf and mssqlsystemresource.ldf) to the local server on the system.

Why User is Unable to Load SQL Resource?

The problem occurs when the setup is unable to replace the current resource database files. The mssqlsystemresource.mdf and mssqlsystemresource.ldf with new versions, and the current resource files are deleted rather than replaced after reboot.

The SQL Server mssqlsystemresource Database

The mssqlsystemresource file database is the physical database that includes all of the definitions for the SQL Server objects details. This resource file database is read-only and inaccessible even to members of the sysadmin server role. Unless the instance is started in single-user mode (with the –m starting option). And accessed via a dedicated administrator connection.

Because the Resource database includes all of the system object code (but no user data or metadata), version upgrades are accomplished by simply changing the Resource database files within the instance’s BINN folder.

Ways Restore a SQL Server Resource Database

The Restoring Resource Database requires copying the mssqlsystemresource.mdf and mssqlsystemresource.ldf files. Copy the files to the place specified in your Disaster Recovery Plan.

Things to Consider with SQL Resource

  • The Resource Database should be located in the same directory as the master database files.
  • In the event of a hardware loss, you will have to rebuild your environment by restoring the master database to a new drive location. Right after while restoring the master database using the WITH MOVE option, make a duplicate of the Resource Database’s .mdf and .ldf files.
  • If you are able to locate an older version of the Resource Database, you will need to reapply the succeeding patches.

Keep SQL Recovery Solution in Your Hand

  • If you find yourself in this or a similar circumstance where you need to restore the resource database without a backup, you’ll need to know the precise version of SQL Server you’re running in order to extract the mssqlsystemresource database files from a setup package.
  • Taking backups of the resource database is a smart idea.
  • To access the resource database, you will require “Dedicated Admin Connections”.
  • In order to access the resource database, you must also start SQL Server in single-user mode.
  • If your issue involves restoring the Master database without a backup, SQL recovery software can assist you.
