RAC数据库DATAGUARD手册
●操作环境：
Primary database ：RACDB 两节点为racdb1,racdb2 ORACLE Enterpresie Linux 5.3；Oracle 10.2.0.4；数据文件，spfile参数，归档日志文件存储系统ASM。
Standby databse ：racdg ORACLE Enterpresie Linux 5.3；Oracle 10.2.0.4；
ext3文件系统；单实例。136********
第一步：确定主库启用归档模式
SQL> archive log list
如果没有启用归档，则：
SQL>conn /as sysdba
SQL > alter system set log_archive_dest_1 = "location=<文件位置>"
SQL > alter system set log_archive_format='arch_%t_%s_%r.arc' scope=spfile;
SQL > shutdown imm ediate
SQL> alter database archivelog;
Oracle 10中已经将log_archive_start 参数废弃，
在RAC下执行ALTER SYSTEM SET LOG_ARCHIVE_DEST_1语句,可以
加scope选项吗?我执行的时候加了scope不管是=memoryspfile,还是both,都报错,在网上搜了一下说不用scope语句即可,我执行了一下,果然可以了,而且和scope=both的效果一样
第二步：设置主库日志处理（每个节点都执行）
ALTER DATABASE FORCE LOGGING;
如果rac的节点数据库使用ASM等cluster文件系统存储spfile和controlfile等数据文件，
则没有必要在每个节点都执行。
第三步：备份主库
mkdir -p /backup/databackup/
chown -R oracle.oinstall /backup
●备份spfile文件
SQL> CREATE PFILE='/backup/databackup/initracdg.ora' FROM SPFILE;
●rman到处主库的数据文件及控制文件
rm an target /
RMAN> backup device type disk format '/backup/databackup/%U' database plus archivelog;
RMAN> backup device type disk format '/backup/databackup/%U' current controlfile for standby;
●将主库的listener.ora, tnsnam es.ora文件复制到/backup/databackup/
cd $ORACLE_HOME/network/admin/*.ora /backup/databackup/
第四步：在备库下建立数据库的文件存方目录
cd $ORACLE_BASE
mkdir -p adm in/rac/bdump
mkdir -p adm in/rac/cdum p
mkdir -p adm in/rac/udump
mkdir -p adm in/rac/adump
mkdir -p adm in/rac/dpdump
mkdir -p adm in/rac/hdump
第五步：将备份的数据从主库COPY到备库
●scp -rp /backup/databackup/* oracle@ip_racbk:/backup/databackup/
●将standby上的listener.ora, tnsnames.ora 拷贝到主机
scp –rp oracle@ip_racbk:$ORACLE_HOME/network/admin/*.ora $ORACLE_BASE
第六步：在备库上执行如下步骤
1.备机上合并listener.ora, tnsnames.ora
cat /backup/databackup/listener.ora >> $ORACLE_HOME/network/admin/listener.ora
cat /backup/databackup/tnsnames.ora >> $ORACLE_HOME/network/admin/tnsnames.ora
?Listener.ora 的内容如下:
SID_LIST_LISTENER_RAC1-ZQGAME =
(SID_LIST =

)
INBOUND_CONNECT_TIMEOUT_LISTENER=0
注：并启动Listener

(SERVICE_NAME = racdb)
(INSTANCE_NAME = racdb2)
)
2.主机上合并listener.ora, tnsnames.ora(每个节点都执行)
cat $ORACLE_BASE/listener.ora >> $ORACLE_HOME/network/admin/listener.ora
cat $ORACLE_BASE/tnsnames.ora >> $ORACLE_HOME/network/admin/tnsnames.ora
?主库Listener.ora内容:

?主库tnsnames.ora内容:

)
3.备机上建立密码文件
cd $ORACLE_HOME/dbs
orapwd file=orapw$ORACLE_SID password=XXX entries=5
4.将spfie文件复制到$ORACLE_HOME/dbs下
cp /backup/databackup/standby.ora $ORACLE_HOME/dbs/initracdg.ora 5.修改其中参数，删除有关集群的参数并添加standby设置参数
[oracle@racdbbk dbs]$ m ore initracdg.ora.bak

6.建立spfile文件
export ORACLE_SID=racdg
sqlplus /nolog
SQL>conn /as sysdba
CREA TE SPFILE FROM PFILE = '$ORACLE_HOME/dbs/initracdg.ora'
7.导入数据到备数据库
sqlplus /nolog
SQL>conn /as sysdba
SQL> STARTUP NOMOUNT
rman target sys/XXX@RAC DB1 auxiliary /
RMAN> duplicate target database for standby;
操作过程如下：
restore not done; all files readonly, offline, or already restored
