Membuat Langganan Pull
Berlaku untuk:
SQL Server Azure SQL Managed Instance
Topik ini menjelaskan cara membuat langganan pull di SQL Server dengan menggunakan SQL Server Management Studio, Transact-SQL, atau Replication Management Objects (RMO).
Menyiapkan langganan pull untuk replikasi P2P dimungkinkan oleh skrip, tetapi tidak tersedia melalui wizard.
Menggunakan SQL Server Management Studio
Buat langganan penarikan di Penerbit atau Pelanggan menggunakan Wizard Langganan Baru. Ikuti halaman dalam wizard untuk:
Tentukan Penerbit dan publikasi.
Pilih tempat agen replikasi akan berjalan. Untuk langganan penarikan, pilih Jalankan setiap agen di Pelanggannya (tarik langganan) di halaman Lokasi Agen Distribusi atau halaman Gabungkan Lokasi Agen, tergantung pada jenis publikasi.
Tentukan Pelanggan dan database langganan.
Tentukan login dan kata sandi yang digunakan untuk koneksi yang dibuat oleh agen replikasi:
Agar langganan rekam jepret dan publikasi transaksional, tentukan kredensial di halaman Keamanan Agen Distribusi.
Agar langganan dapat menggabungkan publikasi, tentukan kredensial di halaman Gabungkan Keamanan Agen.
Untuk informasi tentang izin yang diperlukan oleh setiap agen, lihat Model Keamanan Agen Replikasi.
Tentukan jadwal sinkronisasi dan kapan Pelanggan harus diinisialisasi.
Tentukan opsi tambahan untuk publikasi gabungan: jenis langganan; nilai untuk pemfilteran berparameter; dan informasi untuk sinkronisasi melalui HTTPS jika publikasi diaktifkan untuk sinkronisasi Web.
Tentukan opsi tambahan untuk publikasi transaksional yang memungkinkan pembaruan langganan: apakah Pelanggan harus segera melakukan perubahan di Penerbit atau menulisnya ke antrean; kredensial yang digunakan untuk menyambungkan dari Pelanggan ke Penerbit.
Secara opsional skrip langganan.
Untuk membuat langganan penarikan dari Publisher
Sambungkan ke Publisher di Microsoft SQL Server Management Studio, lalu perluas simpul server.
Perluas folder Replikasi, lalu perluas folder Publikasi Lokal.
Klik kanan publikasi yang ingin Anda buatkan satu atau beberapa langganan, lalu klik Langganan Baru.
Selesaikan halaman di Panduan Langganan Baru.
Untuk membuat langganan penarikan dari Pelanggan
Sambungkan ke Pelanggan di SQL Server Management Studio, lalu perluas simpul server.
Perluas folder Replikasi.
Klik kanan folder Langganan Lokal, lalu klik Langganan Baru.
Pada halaman Publikasi Wizard Langganan Baru, pilih <Temukan Penerbit> SQL Server atau <Temukan Penerbit> Oracle dari daftar drop-down Penerbit.
Sambungkan ke Publisher dalam kotak dialog Sambungkan ke Server .
Pilih publikasi di halaman Publikasi .
Selesaikan halaman di Panduan Langganan Baru.
Menggunakan T-SQL
Langganan penarikan dapat dibuat secara terprogram menggunakan prosedur tersimpan replikasi. Prosedur tersimpan yang digunakan akan bergantung pada jenis publikasi tempat langganan berada.
Untuk membuat langganan penarikan ke rekam jepret atau publikasi transaksi
Di Publisher, verifikasi bahwa publikasi mendukung langganan penarikan dengan menjalankan sp_helppublication (Transact-SQL).
Jika nilai allow_pull dalam tataan hasil adalah 1, maka publikasi mendukung langganan penarikan.
Jika nilai allow_pull adalah 0, jalankan sp_changepublication (Transact-SQL), menentukan allow_pull untuk @property dan true untuk @value.
Di Pelanggan, jalankan sp_addpullsubscription (Transact-SQL). Tentukan @publisher dan @publication. Untuk informasi tentang memperbarui langganan, lihat Membuat Langganan yang Dapat Diperbarui ke Publikasi Transaksional.
Di Pelanggan, jalankan sp_addpullsubscription_agent (Transact-SQL). Tentukan yang berikut ini:
Parameter @publisher, @publisher_db, dan @publication .
Kredensial Microsoft Windows tempat Agen Distribusi di Pelanggan berjalan untuk @job_login dan @job_password.
Catatan
Koneksi yang dibuat menggunakan Autentikasi Terintegrasi Windows selalu menggunakan kredensial Windows yang ditentukan oleh @job_login dan @job_password. Agen Distribusi selalu membuat koneksi lokal ke Pelanggan menggunakan Autentikasi Terintegrasi Windows. Secara default, agen akan terhubung ke Distributor menggunakan Autentikasi Terintegrasi Windows.
(Opsional) Nilai 0 untuk @distributor_security_mode dan informasi masuk SQL Server untuk @distributor_login dan @distributor_password, jika Anda perlu menggunakan Autentikasi SQL Server saat menyambungkan ke Distributor.
Jadwal untuk pekerjaan Agen Distribusi untuk langganan ini. Untuk informasi selengkapnya, lihat Menentukan Jadwal Sinkronisasi.
Di Publisher, jalankan sp_addsubscription (Transact-SQL) untuk mendaftarkan langganan pull. Tentukan @publication, @subscriber, dan @destination_db. Tentukan nilai tarik untuk @subscription_type.
Untuk membuat langganan penarikan ke publikasi gabungan
Di Publisher, verifikasi bahwa publikasi mendukung langganan penarikan dengan menjalankan sp_helpmergepublication (Transact-SQL).
Jika nilai allow_pull dalam tataan hasil adalah 1, maka publikasi mendukung langganan penarikan.
Jika nilai allow_pull adalah 0, jalankan sp_changemergepublication (Transact-SQL), tentukan allow_pull untuk @property dan true untuk @value.
Di Pelanggan, jalankan sp_addmergepullsubscription (Transact-SQL). Tentukan @publisher, @publisher_db, @publication, dan parameter berikut:
@subscriber_type - tentukan lokal untuk langganan klien dan global untuk langganan server.
@subscription_priority - Tentukan prioritas untuk langganan (0,00 hingga 99,99). Ini hanya diperlukan untuk langganan server.
Untuk informasi selengkapnya, lihat Deteksi dan Resolusi Konflik Replikasi Gabungan Tingkat Lanjut.
Di Pelanggan, jalankan sp_addmergepullsubscription_agent (Transact-SQL). Tentukan parameter berikut:
@publisher, @publisher_db, dan @publication.
Kredensial Windows tempat Agen Penggabungan di Pelanggan berjalan untuk @job_login dan @job_password.
Catatan
Koneksi yang dibuat menggunakan Autentikasi Terintegrasi Windows selalu menggunakan kredensial Windows yang ditentukan oleh @job_login dan @job_password. Agen Penggabungan selalu membuat koneksi lokal ke Pelanggan menggunakan Autentikasi Terintegrasi Windows. Secara default, agen akan tersambung ke Distributor dan Penerbit menggunakan Autentikasi Terintegrasi Windows.
(Opsional) Nilai 0 untuk @distributor_security_mode dan informasi masuk SQL Server untuk @distributor_login dan @distributor_password, jika Anda perlu menggunakan Autentikasi SQL Server saat menyambungkan ke Distributor.
(Opsional) Nilai 0 untuk @publisher_security_mode dan informasi masuk SQL Server untuk @publisher_login dan @publisher_password, jika Anda perlu menggunakan Autentikasi SQL Server saat menyambungkan ke Penerbit.
Jadwal untuk pekerjaan Agen Penggabungan untuk langganan ini. Untuk informasi selengkapnya, lihat Membuat Langganan yang Dapat Diperbarui ke Publikasi Transaksi.
Di Publisher, jalankan sp_addmergesubscription (Transact-SQL). Tentukan @publication, @subscriber, @subscriber_db, dan nilai tarik untuk @subscription_type. Ini mendaftarkan langganan penarikan.

Menggunakan Objek Manajemen Replikasi (RMO)
Kelas RMO yang digunakan untuk membuat langganan pull bergantung pada jenis publikasi tempat langganan berada.
Untuk membuat langganan penarikan ke rekam jepret atau publikasi transaksi
Buat koneksi ke Pelanggan dan Penerbit dengan menggunakan ServerConnection Kelas .
Buat instans TransPublication kelas dengan menggunakan koneksi Publisher dari langkah 1. Tentukan Name, DatabaseName dan ConnectionContext.
Panggil LoadProperties metode. Jika metode ini mengembalikan false, properti yang ditentukan di langkah 2 salah atau publikasi tidak ada di server.
Lakukan bitwise logis AND (& di Visual C# dan Dan di Visual Basic) antara Attributes properti dan AllowPull. Jika hasilnya adalah None, atur Attributes ke hasil bitwise logis OR (| di Visual C# dan Atau di Visual Basic) antara Attributes dan AllowPull. Kemudian, panggil CommitPropertyChanges untuk mengaktifkan langganan penarikan.
Jika database langganan tidak ada, buat dengan menggunakan Database kelas . Untuk informasi selengkapnya, lihat Membuat, Mengubah, dan Menghapus Database.
Membuat instans kelas TransPullSubscription.
Atur properti langganan berikut ini:
ke ServerConnection Pelanggan yang dibuat di langkah 1 untuk ConnectionContext.
Nama database langganan untuk DatabaseName.
Nama Publisher untuk PublisherName.
Nama database publikasi untuk PublicationDBName.
Nama publikasi untuk PublicationName.
Bidang Login SynchronizationAgentProcessSecurity dan Password untuk memberikan kredensial untuk akun Microsoft Windows tempat Agen Distribusi berjalan di Pelanggan. Akun ini digunakan untuk membuat koneksi lokal ke Pelanggan dan untuk membuat koneksi jarak jauh menggunakan Autentikasi Windows.
Catatan
Pengaturan SynchronizationAgentProcessSecurity tidak diperlukan saat langganan dibuat oleh anggota peran server tetap sysadmin , namun disarankan. Dalam hal ini, agen akan meniru akun SQL Server Agent. Untuk informasi selengkapnya, lihat Model Keamanan Agen Replikasi.
(Opsional) Nilai true untuk CreateSyncAgentByDefault membuat pekerjaan agen yang digunakan untuk menyinkronkan langganan. Jika Anda menentukan false (default), langganan hanya dapat disinkronkan secara terprogram dan Anda harus menentukan properti TransSynchronizationAgent tambahan saat Anda mengakses objek ini dari SynchronizationAgent properti . Untuk informasi selengkapnya, lihat Menyinkronkan Langganan Pull.
Catatan
SQL Server Agent tidak tersedia di setiap edisi Microsoft SQL Server. Untuk daftar fitur yang didukung oleh edisi SQL Server, lihat Edisi dan fitur yang didukung SQL Server 2022. Ketika Anda menentukan nilai true untuk Pelanggan Ekspres, pekerjaan agen tidak dibuat. Namun, metadata terkait langganan penting disimpan di Pelanggan.
(Opsional) Atur SqlStandardLogin bidang DistributorSecurity dan SqlStandardPassword atau SecureSqlStandardPassword saat menggunakan Autentikasi SQL Server untuk menyambungkan ke Distributor.
Panggil Create metode.
Menggunakan instans TransPublication kelas dari langkah 2, panggil MakePullSubscriptionWellKnown metode untuk mendaftarkan langganan pull dengan Publisher. Jika pendaftaran ini sudah ada, pengecualian terjadi.
Untuk membuat langganan penarikan ke publikasi gabungan
Buat koneksi ke Pelanggan dan Penerbit dengan menggunakan ServerConnection kelas .
Buat instans MergePublication kelas dengan menggunakan koneksi Publisher dari langkah 1. Tentukan Name, DatabaseName, dan ConnectionContext.
Panggil LoadProperties metode. Jika metode ini mengembalikan false, properti yang ditentukan di langkah 2 salah atau publikasi tidak ada di server.
Lakukan bitwise logis AND (& di Visual C# dan Dan di Visual Basic) antara Attributes properti dan AllowPull. Jika hasilnya adalah None, atur Attributes ke hasil bitwise logis OR (| di Visual C# dan Atau di Visual Basic) antara Attributes dan AllowPull. Kemudian, panggil CommitPropertyChanges untuk mengaktifkan langganan penarikan.
Jika database langganan tidak ada, buat dengan menggunakan Database kelas . Untuk informasi selengkapnya, lihat Membuat, Mengubah, dan Menghapus Database.
