GOAL

NOTE: In the images and/or the document content below, the user information and environment data used represents fictitious data from the Oracle sample schema(s), Public Documentation delivered with an Oracle database product or other training material. Any similarity to actual environments, actual persons, living or dead, is purely coincidental and not intended in any manner.

For the purposes of this document, the following fictitious environment is used as an example to describe the procedure:  为了本文档的目的，以下虚拟环境用作描述此过程的示例

Primary db_name and db_unique_name: BOSTON

Standby db_name:  BOSTON (same as primary db_name)

Standby db_unique_name:  CHICAGO

Directory:  u01/app/oracle
 
NOTE : We cannot create a physical standby at PDB(plugable Database) level. It should be at CDB(Container Database) level i.e entire primary CDB should be cloned/created as physical Standby.
注意：我们无法在PDB（可插入数据库）级别上创建物理备用数据库。它应处于CDB（容器数据库）级别，即应克隆/创建整个主CDB作为物理备用数据库。

Steps includes,  步骤包括

1. Create necessary Directory on standby server.  在备用服务器上创建必要的目录

2.Create pfile and password.  创建pfile和密码

3. Make static listener entry on standby server.  在备用服务器上进行静态侦听器条目

4. Use RMAN Duplicate ..from Active Database to clone Primary CDB.  使用RMAN Duplicate ..from Active Database克隆主CDB

5. Configure primary for remote log shipping and verify MRP progress on standby.  配置主数据库进行远程日志传送，并验证备用数据库上的MRP进度

SOLUTION

1. Create addition Directory on standby server  在备用服务器上创建附加目录

mkdir -p /u01/app/oracle/admin/chicago/adump

mkdir -p /u01/app/oracle/oradata/chicago

mkdir -p /u01/app/oracle/fast_recovery_area/chicago

mkdir -p /u01/app/oracle/oradata/chicago1/pdbseed

mkdir -p /u01/app/oracle/oradata/chicago/db1

NOTE : Direcories like pdbseed,chicago1 are specific to 12c.  注意：像 pdbseed，chicago1 这样的目录特定于12c

2. Create pfile

echo 'db_name=boston' > /u01/app/oracle/product/12.1.0/dbhome_1/dbs/initchicago.ora

3. Create Password file or copy from primary

orapwd file=/u01/app/oracle/product/12.1.0/dbhome_1/dbs/orapwchicago password=<password>

4. Make static listener entry

cd $ORACLE_HOME/network/admin

vi listener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC=

(GLOBAL_DBNAME = chicago)

(ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1)

(SID_NAME = chicago)

)

)

-reload or restart listener.

lsnrctl stop

lsnrctl start

5. Start the AUX instance at standby side.  在备用端启动AUX实例

sqlplus / as sysdba

startup nomount pfile='$ORACLE_HOME/dbs/initchicago.ora';

6. Initiate RMAN DUPLICATE from.. active database to create standby with target connected to primary instance.
  从活动数据库启动RMAN DUPLICATE，以将目标连接到主实例来创建备用数据库

rman target sys/<password>@boston auxiliary sys/<password>@chicago

run

{

allocate channel c1 type disk;

allocate channel c2 type disk;

allocate channel c3 type disk;

allocate channel c4 type disk;

allocate channel prim type disk;

allocate auxiliary channel aux type disk;

duplicate target database for standby from active database spfile

parameter_value_convert 'boston','chicago'

set db_file_name_convert='boston','chicago'

set log_file_name_convert='boston','chicago'

set log_archive_max_processes='10'

set log_archive_config='dg_config=(boston,chicago)';

sql channel aux "alter database add standby logfile ''/u01/app/oracle/oradata/chicago/stdbyredo1.log'' size 50M";

sql channel aux "alter database add standby logfile ''/u01/app/oracle/oradata/chicago/stdbyredo2.log'' size 50M";

7. Prepare Primary database to ship REDO to standby.  准备主数据库以将REDO发送到备用数据库

a, Define log_archive_config value,  定义log_archive_config值

This parameter should have all the participating databases in the same DG configuration. Lets say this parameter tells about primary and all the participating standby(physical,logical,far sync) in DG configuration.
此参数应使所有参与的数据库处于同一DG配置中。可以说，此参数说明了DG配置中的主要和所有参与的备用数据库(physical,logical,far sync)

SQL>ALTER SYSTEM SET log_archive_config='dg_config=(boston,Chicago)' SCOPE=BOTH;

System altered.

NOTE : log_archive_config value is not case sensitive.  --不区分大小写

b. Set remote log shipping,  设置远程日志传送

@primary,

SQL>alter system set log_archive_dest_6='service=chicago async valid_for=(all_logfiles,primary_role) db_unique_name=chicago';

System altered.                                                                         
NOTE : Here primary use ASYNC redo transport method to ship REDO to standby.  注意：这里主要使用ASYNC重做传输方法将REDO发送到备用数据库
For details on REDO transport related parameters refer,
Data Guard Concepts and Administration
12c Release 1 (12.1)

TOPIC : 17 LOG_ARCHIVE_DEST_n Parameter Attributes

c. Verify redo log shipping,  验证重做日志传送

SQL> alter system switch logfile;

System altered.

SQL> col error for a30

SQL> select dest_id,error,status,log_sequence,applied_scn from v$archive_dest where dest_id=2;

   DEST_ID ERROR                          STATUS    LOG_SEQUENCE APPLIED_SCN

8. Verify Standby is applying,  确认备用服务器正在应用

NOTE : MRP already started after the RMAN duplicate.  注意：RMAN复制后，MRP已经启动

SQL> select process,status,thread#,sequence#,blocks from v#managed_standby where process like '%MRP%';

process      status                   thread# sequence# blocks
