If you read my first tip on expired TDE certificates, you know that a database can still work even after the certificate used for TDE has expired.
Now you might be wondering how you can generate a new certificate to replace the previous certificate and the steps if the database is in an Availability Group.
If your database is involved in any HA or DR, the new certificate needs to be restored to all the secondary SQL Server instances.
In our scenario, database [AGplaceholder] is involved in an Availability Group (AG).
Next you need to issue an ALTER SYMMETRIC KEY command in the context of the user database (AGplaceholder in our example) to bind the newly created certificate to the Database Encryption Key (DEK).
If a database encryption key has been modified twice, a log backup must be performed before the database encryption key can be modified again.
The AG dashboard will show the Synchronizing State as Not Synchronizing as soon as the new certificate was bound on the primary AG replica.
To avoid conflicting with official updates, here's the recommended way to create an unofficial update.In our tip, it is the first time we are modifying the encryption key, so the command below will work fine to bind the DEK to the certificate.USE [master] GO SELECT DB_NAME(db.database_id) Db Name, db.encryption_state , encryptor_type, cer.name, cer.expiry_date, cer.subject FROM sys.dm_database_encryption_keys db JOIN sys.certificates cer ON db.encryptor_thumbprint = cer.thumbprint GO It is up to you whether you want to drop the old certificate from the SQL Server instance.Publish your own blog with drag-and-drop ease, using built-in professional templates.Keep your colleagues up to date with projects, the files you’re working on, and pictures or podcasts.17 and 20, the Crimson Tide now faces perhaps its toughest string of games with a little momentum. That leaves the program's first NCAA tournament bid since 2012 in focus. 7 seed in ESPN's bracket projection released before it beat LSU 80-65 on Tuesday night. 8 seed in its latest forecast that also came before Tuesday's action. Interestingly, the Tide has a worse record in Quadrant 2 games than the higher level. A rematch at Auburn is next followed by home games with Arkansas (No. You should always keep a backup of the old certificate in case you need to restore a TDE enabled database using an older backup that used the old key. It is paramount to backup the TDE certificate after any certificate changes as this is required to restore the database to another SQL Server instance.We can issue a backup certificate command for the new certificate as shown below.Your searchable blog is the perfect place to store information for your team, or just for your own reference.Sometimes a mod will stop working due to a major game update; SMAPI automatically disables incompatible mods.
