Replication latency yog tus nqi ntawm lub sij hawm nws yuav siv sij hawm rau ib tug lw uas tshwm sim nyob rau hauv thawj database yuav tsum tau siv rau lub rov ua dua database. Lub sijhawm suav nrog Rov ua dua Kev ua tus neeg sawv cev, Rov ua dua Server processing, thiab kev siv network.

Ib yam li ib tug yuav nug, kuv tuaj yeem qhia tau li cas yog SQL Server replication yog latency?

Siv SQL Server Replication Monitor

  1. Nthuav ib pab Publisher nyob rau sab laug pane, nthuav ib tug Publisher, thiab ces nias ib tug tshaj tawm.
  2. Nyem rau Tracer Tokens tab.
  3. Nyem Insert Tracer.
  4. Saib lub sijhawm dhau mus rau tus lej cim rau hauv kab hauv qab no: Tus Tshaj Tawm rau Tus Neeg Muag Khoom, Tus Muag Khoom rau Cov Neeg Sau Npe, Tag Nrho Latency.

Ib yam li ntawd, kuv yuav ua li cas thiaj kuaj tau kuv qhov kev hloov pauv hloov pauv? Txhawm rau siv nws nkag rau hauv SQL Server Management Studio thiab txuas mus rau tus tshaj tawm. Txoj nyem rau ntawm Rov ua dua hauv tsob ntoo thiab xaiv Launch Replication Monitor (nws yuav tsis tau sau npe raws nraim li ntawd). Txuas qhov ntawd rau tus xa khoom thiab koj tuaj yeem ua tau saib cov xwm txheej replication.

Tom qab ntawd, lo lus nug yog, dab tsi yog tracer token hauv SQL replication?

Kab Token Muaj los ntawm Rov ua dua Saib xyuas lossis ntawm TSQL nqe lus, Tracer Tokens yog cov ntawv teev sijhawm tshwj xeeb sau rau Tus Tshaj Tawm Cov Ntawv Teev Npe thiab khaws los ntawm Tus Neeg Nyeem Ntawv. Tom qab ntawd lawv tau nyeem los ntawm Tus Saib Xyuas Kev Tshaj Tawm thiab sau rau tus neeg siv khoom.

Yuav ua li cas SQL Server txhim kho replication kev ua tau zoo?

Server thiab Network

  1. Teem qhov tsawg kawg nkaus thiab siab kawg ntawm lub cim xeeb faib rau Microsoft SQL Server Database Engine.
  2. Xyuas kom muaj kev faib cov ntaub ntawv database thiab cov ntaub ntawv teev cia kom raug.
  3. Xav txog kev ntxiv lub cim xeeb rau cov servers siv hauv replication, tshwj xeeb tshaj yog Distributor.
  4. Siv computers multiprocessor.
  5. Siv lub network ceev.
