12.2 Active Dataguard in CDB on Non-ASM

Creating Physical Standby Active DataGuard Configuration in 12.2.0.1 Container Database

AIM: Without shutting down primary, we need to create physical standby database using RMAN DUPLICATE FROM ACTIVE DATABASE command on 12.2 Database in CDB/PDB environment (No need to take backup of primary database)

0. Introduction

PLEASE NOTE in 12c Data Guard is set up at the Container level and not the individual Pluggable database level as the redo log files only belong to the Container database and the individual pluggable databases do not have their own online redo log files.

Definition of Active Dataguard:

Oracle Active Data Guard enables read-only access to a physical standby database for queries, sorting, reporting, web-based access, etc., while continuously applying changes received from the production/primary database.

3. Check Password File on Primary

4. Configure a Standby Redo Log on Primary

Note : 

-- 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.

7. Transfer SPFILE AND PASSWORD FILE TO STANDBY SIDE

Copy the password file from the primary $ORACLE_HOME/dbs and rename it to the standby database name.
The username is required to be SYS and the password needs to be the same on the Primary and Standby.
The best practice for this is to copy the passwordfile as suggested.
The password file name must match the instance name/SID used at the standby site, not the DB_NAME.

19. Verify the Physical Standby Database Is Performing Properly

The Pluggable database PDB1 has been opened in READ ONLY mode, but the Container Database is running as an Active Standby database and applying changes as they are received from the primary even when the Standby Container database and all the associated pluggable databases have been opened in read only mode. This means Active Dataguard is working..

On Primary

SQL> alter session set container=pdb1;

Session altered.

SQL> create user raj identified by raj default tablespace users temporary tablespace temp;

User created.

SQL> grant connect,resource to raj;

Grant succeeded.

SQL> alter user raj quota unlimited on users;

User altered.
