Memindahkan banyak basis data dari C: ke D: sekaligus

Saya memiliki SQL Server 2008 R2 dengan 323 database yang memakan sekitar 14 GB pada drive C: saya, SSD yang cepat.

Karena saya ingin mendapatkan kembali ruang pada drive C: saya, saya ingin memindahkannya ke drive D: saya.

Saya telah menemukan artikel MSDN ini , tetapi itu tampaknya merupakan prosedur untuk memindahkan hanya satu basis data.

Apakah ada cara atau skrip otomatis untuk memindahkan semua basis data saya sekaligus?

Saya menggunakan Powershell untuk pekerjaan semacam ini. Bahkan, saya menggunakan Powershell untuk menghasilkan Powershell, karena saya memiliki skrip yang akan mengulangi basis data saya dan menghasilkan skrip langkah terakhir saya. Anda harus memindahkan setiap basis data satu per satu, tetapi ini setidaknya akan membantu Anda skrip 90% dari pekerjaan.

Peringatan

• Script memindahkan semua file, terlepas dari lokasi sumbernya, ke tujuan yang sama. Anda perlu mengubah jalur lokasi khusus.
• Skrip ini dirancang untuk dijalankan di server tempat Anda perlu memindahkan file (lihat semua penggunaan localhost '). Ganti localhost dengan nama instance Anda jika Anda menjalankan ini dari jarak jauh.
• Pengguna yang Anda jalankan ini membutuhkan akses ke semua jalur folder yang terlibat dalam gerakan, baik untuk memperbarui informasi nama file SQL server dan untuk memindahkan file.
• Saya menggunakan InvokeSQLCmd untuk eksekusi Offline / Online karena sifat funky dari metode .SetOffline () dan .SetOnline. Saya menemukan ini lebih dapat diandalkan.

Anda dapat menggunakan metode Alter database Modify File atau Detach / Attach.

Catatan: Keduanya akan membutuhkan waktu henti, jadi harus dilakukan selama jendela pemeliharaan.

Ini mengasumsikan bahwa Anda memiliki struktur direktori yang sama pada drive baru misalnya C: \ data \ dan D: \ Data.

- menggunakan database Alter dengan metode Modify (lebih disukai)

Satu-satunya cara yang saya tahu untuk melakukan banyak DB sekaligus adalah dengan skrip langkah untuk beberapa DB sekaligus.

ALTER DATABASE database_nameA SET OFFLINE WITH ROLLBACK IMMEDIATE;
ALTER DATABASE database_nameB SET OFFLINE WITH ROLLBACK IMMEDIATE;
ALTER DATABASE database_nameC SET OFFLINE WITH ROLLBACK IMMEDIATE;
-------

Di sini Anda dapat memindahkan file secara manual, atau menulis skrip untuk melakukannya. Mungkin menggunakan xp_cmdshell atau beberapa alat. Mungkin lebih mudah untuk hanya memindahkan file dengan tangan. Tandai banyak dari mereka, lalu seret dan lepas.

-------
ALTER DATABASE database_nameA MODIFY FILE ( NAME = logical_name, FILENAME = 'new_path\os_file_name' );
ALTER DATABASE database_nameB MODIFY FILE ( NAME = logical_name, FILENAME = 'new_path\os_file_name' );
ALTER DATABASE database_nameC MODIFY FILE ( NAME = logical_name, FILENAME = 'new_path\os_file_name' );

ALTER DATABASE database_nameA SET ONLINE;
ALTER DATABASE database_nameB SET ONLINE;
ALTER DATABASE database_nameC SET ONLINE;

Tentu saja jika Anda memindahkan file data dan file log Anda harus memastikan Anda melakukan bagian MODIFIKASI FILE untuk setiap bagian.
