Mengajukan alamat read-only.
Deskripsi operasi
Mesin yang didukung
RDS MySQL
RDS SQL Server
Deskripsi
Untuk instans utama SQL Server yang memiliki instans read-only, Anda dapat membuat alamat read-only terpadu. Setelah alamat ini dibuat, alamat akses yang ada pada instans utama dan instans read-only, serta penggunaan normal endpoint jaringan internal dan eksternal, tidak terpengaruh.
Prasyarat
Saat Anda memanggil API ini, instans harus memenuhi kondisi berikut; jika tidak, operasi akan gagal:
Instans MySQL menggunakan proxy bersama.
Instans berada dalam status Running.
Instans memiliki instans read-only.
Instans tidak memiliki tugas migrasi DTS yang sedang berjalan.
- Instans merupakan salah satu versi berikut:
Edisi Kluster SQL Server.
MySQL 5.7 Edisi Ketersediaan Tinggi (SSD lokal)
