【Oracle】OGG数据初始化之RMAN

实验环境：

源端、目标端：

DataBase：10.2.0.1.0

OS：OEL5.6

OGG：fbo_ggs_Linux_x86_ora11g_32bit

源端使用rman进行备份全库：

RMAN> run{

源端数据库查询：

SYS@ORCL>select * from Gv$log;

INST_ID GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM

---------- ---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- ---------

1 1 1 38 52428800 1 NO CURRENT 484272 21-JUL-14

1 3 1 37 52428800 1 YES INACTIVE 484267 21-JUL-14

记录此时非活动日志组的SCN，有多组的时候我们取最大的FIRST_CHANGE#，在这里是484267。

将源端库的init<SID>.ora发送到目标端：

SYS@ORCL>create pfile from spfile;

File created.

[oracle@edbjr2p1 dbs]$ scp initORCL.ora edbjr2p2:$ORACLE_HOME/dbs

oracle@edbjr2p2's password:

initORCL.ora 100% 1049 1.0KB/s 00:00

在目标端建立全部文件夹，然后将备份传过去：

目标端：

[oracle@edbjr2p2 oracle]$ pwd

/u01/app/oracle

[oracle@edbjr2p2 oracle]$ mkdir -p admin/ORCL/{a,b,c,u}dump

[oracle@edbjr2p2 oracle]$ mkdir flash_recovery_area/ORCL

[oracle@edbjr2p2 oracle]$ mkdir -p oradata/ORCL

源端：

[oracle@edbjr2p1 bak]$ ls

bk_controlfile 100% 7232KB 7.1MB/s 00:00

目标端将库启动到nomount状态：

[oracle@edbjr2p2 ~]$ export ORACLE_SID=ORCL

[oracle@edbjr2p2 ~]$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Mon Jul 21 16:11:45 2014

然后使用rman将数据库恢复出来：

RMAN> restore controlfile from '/home/oracle/bak/bk_controlfile';

Starting restore at 21-JUL-14

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

Finished restore at 21-JUL-14

然后recover数据库到前边我们记录的SCN处：

RMAN>run

{

SET UNTIL SCN 484267;

RECOVER DATABASE;

}2> 3> 4> 5>

目标端查看此时SCN并打开数据库：

SQL> SELECT CHECKPOINT_CHANGE#,CHECKPOINT_TIME FROM V$DATAFILE_HEADER;

CHECKPOINT_CHANGE# CHECKPOIN

------------------ ---------

484267 21-JUL-14

6 rows selected.

SQL> alter database open resetlogs;

Database altered.

目标端启动Replicat进程：

GGSCI (edbjr2p2) 1>start repya ,afterscn 484267

此处使用的SCN是我们之前记录的SCN。

由于数据文件恢复到了这个SCN，rman保证了这个SCN之前的源端和目标端库的数据一致性，OGG仅仅要应用此SCN之后出现的数据变化就可以。
