Oracle Data Guard Physical Standby Configuration Part1

                      

Stage-1 How to Create a Physical Standby Database using Backup Pieces
High Level Steps

Goal : How to Create Physical Standby Database using RMAN Backup With Duplicate Command

  1. Environment
    Environment detail Primary Standby
    Database Name dbwrprd dbwrprd
    Db Unique name dbwrprd dbwrstd
    Server IP 192.168.1.24 192.168.1.25
    Server Name Prod21 Prod22
  2. Enable Flashback,Force Logging and archivelog mode on Primary
    [oracle@Prod21 ~]$ export ORACLE_SID=dbwrprd
    [oracle@Prod21 ~]$ sqlplus / as sysdba

3.Configure a Standby Redo Log on Primary

— Since we have 3 online redo log file groups, we need to create 4(3+1) Standby redo log file groups
— Standy Redo logs files come into picture only when protection mode is Maximum Availability and Maximum Protection.

Standby Server Setup (Manual)

1.Create the necessary directories on the standby server.

mkdir -p /u01/app/oracle/oradata/dbwrstd
mkdir -p /u01/app/oracle/fast_recovery_area/dbwrstd
mkdir -p /u01/app/oracle/admin/dbwrstd/adump
mkdir -p /u01/backup/

2.Copy the files from the primary to the standby server.( Login in to primary server and start copy)
