1. 配置好主庫參數(shù)文件：

   

   成都創(chuàng)新互聯(lián)公司成立與2013年，是專業(yè)互聯(lián)網(wǎng)技術(shù)服務(wù)公司，擁有項目成都網(wǎng)站建設(shè)、成都網(wǎng)站設(shè)計網(wǎng)站策劃，項目實施與項目整合能力。我們以讓每一個夢想脫穎而出為使命，1280元平邑做網(wǎng)站,已為上家服務(wù),為平邑各地企業(yè)和個人服務(wù),聯(lián)系電話:18982081108

添加：

*.log_archive_config='DG_CONFIG=(CWFOL,CWFOLB)'
*.log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=CWFOL'
*.log_archive_dest_2='SERVICE=CWFOLB LGWR SYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=CWFOLB'

重啟每個節(jié)點：

2.為主庫添加standby log：

alter database add standby logfile thread 1('+DATA','+FRA') size 200M;
alter database add standby logfile thread 1('+DATA','+FRA') size 200M;
alter database add standby logfile thread 1('+DATA','+FRA') size 200M;
alter database add standby logfile thread 1('+DATA','+FRA') size 200M;
alter database add standby logfile thread 1('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;

3.配置靜態(tài)監(jiān)聽，，主庫和備庫，各節(jié)點，，，

4.主庫開啟閃回和強制日志：

5.生成密碼文件：

orapwd file='$ORACLE_HOME/dbs/orapwCWFOL1' password=oracle entries=5 force=y ignorecase=y;
orapwd file='$ORACLE_HOME/dbs/orapwCWFOL2' password=oracle entries=5 force=y ignorecase=y;
orapwd file='$ORACLE_HOME/dbs/orapwCWFOLB' password=oracle entries=5 force=y ignorecase=y;

或者在一個節(jié)點生成后，然后拷貝到別的節(jié)點，重新命名。

6.備庫編輯一個文件，只需要db_name：

[oracle@foldg dbs]$ cat initCWFOLB.ora
db_name=CWFOLB

7.編輯duplicate.sql

[oracle@foldb1 ~]$ cat duplicate.sql
duplicate target database
for standby
from active database
DORECOVER
spfile
set service_names='CWFOLB'
set db_unique_name='CWFOLB'
set log_archive_dest_1='location=+FRA VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=CWFOLB'
set log_archive_dest_2='SERVICE=COWELLORC  LGWR SYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=CWFOL'
set standby_file_management='AUTO'
set fal_server='CWFOL'
set fal_client='CWFOLB'
set control_files='+DATA'
set cluster_database='false';

出現(xiàn)的錯誤：

1.

MAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of Duplicate Db command at 01/28/2016 13:03:45

ORA-00132: syntax error or unresolved network name 'foldb-cluster-scan:1521'

RMAN> **end-of-file**

*.remote_listener='foldb-cluster-scan:1521'

解決辦法：再主庫上去掉這個參數(shù)，復(fù)制完成后，修改回來。

2.主庫和備庫無法進行實時同步， 狀態(tài)為wait_for_log.需要alter system switch logfile才行.

原因是在備庫上沒有針對節(jié)點2的standby log，添加：

alter database add standby logfile thread 2('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;
alter database add standby logfile thread 2('+DATA','+FRA') size 200M;

正常結(jié)果如下：

SQL> select status from v$managed_standby;
