  1. Tsim ib daim ntawv theej ntawm Thawj Tswj Hwm Database Cov ntaub ntawv.
  2. Tsim Control File rau lub Standby Database .
  3. Npaj ib qho Initialization Parameter File rau lub Standby Database .
  4. Luam cov ntaub ntawv los ntawm Primary System rau hauv Standby Qhov system.
  5. Teeb tsa Ib puag ncig los txhawb lub Standby Database .
  6. Pib lub cev Standby Database .

Hauv qhov no, kuv yuav ua li cas thiaj tsim tau cov ntaub ntawv standby?

Ntawm no yog cov txheej txheem los ntawm kauj ruam

  1. Kauj Ruam 1: Tsim cov qauv ntawv.
  2. Kauj ruam 2: Luam peb pfile.
  3. Kauj ruam 3: Thaub qab controlfile rau Standby.
  4. Kauj ruam 4: Hloov pauv rau pfile.
  5. Kauj ruam 5: Ua ib tug Password ntaub ntawv.
  6. Kauj ruam 6: Pib lub koom haum pab / standby database.
  7. Kauj ruam 7: Configure Network.
  8. Kauj ruam 8: Duplicate database.

Tsis tas li ntawd, dab tsi yog qhov standby database hauv Oracle? A standby database yog a database replica tsim los ntawm ib tug thaub qab ntawm ib tug thawj database . Los ntawm kev siv archived redo cav los ntawm thawj database mus rau standby database , koj tuaj yeem khaws ob databases synchronized. A standby database muaj lub hom phiaj tseem ceeb hauv qab no: kev tiv thaiv kev puas tsuaj. Kev tiv thaiv cov ntaub ntawv kev noj nyiaj txiag.

Xav txog qhov no, kuv yuav ua li cas los tsim ib qho chaw khaws cia hauv Oracle 12c?

Piv txwv Project: Tsim ib lub cev Standby Server

  1. Ua kom tiav cov kauj ruam hauv qab no ntawm tus thawj server:
  2. Configure lub redo thauj authentication; siv cov ntaub ntawv nkag mus rau tej thaj chaw deb password.
  3. Ntxiv standby logfiles rau thawj server.
  4. Teem cov kev pib ua ntej ntawm tus thawj server:
  5. Muab tus thawj neeg rau zaub mov hauv ARCHIVELOG MODE.

Peb puas tuaj yeem nqa RMAN thaub qab ntawm standby database?

Thaum twg koj muaj active standby database nyob rau hauv qhov chaw, koj tuaj yeem nqa qhov zoo los ntawm kev teem caij / khiav tag nrho RMAN thaub qab ntawm thawj database ntawm nws standby database . Cov thaub qab ua dhau ntawm standby database yog tag nrho interchangeable, thiab yuav tsum tsis muaj kev hloov nyob rau hauv lub RMAN tsab ntawv lossis cov lus txib.
