Oracle数据保护DataGuard安装和配置二
续接上一篇。
主库上的操作
强制日志
Alter database force logging;开启归档，指定归档路径
Shutdown immediate;
Startup mount;
Alter database archivelog;
Alter system set log_archive_dest_1 = ‘’;
Alter database open;设置相关参数，通过pfile方式设置
create pfile='/home/oracle/pfile.txt' from spfile;
Shutdown immediate;编辑pfile文件
Vi /home/oracle/pfile.txt

编写listener.ora

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prim_new.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)编写tnsnames.ora
prim =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prim_new.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = prim)
)
)
pdg =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = pdg_new.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = pdg)

)这里的名字就是对应pfile中参数service后面的服务名。
select name,remote_archive,database_role,guard_status,db_unique_name from v$database;查看主状态,是否已经就绪：

ORCL ENABLED PRIMARY NONE prim
备库需要的相关文件
密码文件
在主库上：
生成：
[oracle@prim_new database]$ cd $ORACLE_HOME/dbs
[oracle@prim_new dbs]$ orapwd file=./orapw$ORACLE_SID password=oracle123 force=y然后scp传输到备库，需要在同一个目录下：
[oracle@prim_new dbs]$ scp ./orapw$ORACLE_SID pdg.up.com:$ORACLE_HOME/dbs/控制文件
在主库上生成控制文件：
alter database create standby controlfile as '/u01/control01.ctl';然后传输到与主库同一个目录下。由于备机上时安装了与主机上完全相同目录的数据库，那么只需要将原来的文件删除保留目录就行，先备机上（相应目录上）删除oradata下面的所有文件。
备机上：
Shutdown immediate;
主机上：
scp /u01/control01.ctl pdg_new.com:/u01/oracle/oradata/orcl/control01.ctl
scp /u01/control01.ctl pdg_new.com:/u01/oracle/fast_recovery_area/orcl/control02.ctl
其他核心文件
数据文件，redo，归档文件全部传输到备库上，此时我将主库处于mount状态
主机上：shutdown immediate;
Startup mount;
Redo:
[oracle@prim_new orcl]$ scp *.log pdg_new.com:/u01/oracle/oradata/orcl/
Dbf:
[oracle@prim_new orcl]$ scp *.dbf pdg_new.com:/u01/oracle/oradata/orcl/
Archivelog:
[oracle@prim_new orcl]$ scp /u01/oracle/archivelog/*.arc pdg_new.com:/u01/oracle/archivelog/
Listener,tnsnames.ora
从主库上传输给备机，并且适当修改
[oracle@prim_new orcl]$ cd /u01/oracle/product/11.2.0/network/admin/
[oracle@prim_new admin]$ ll
total 16

[oracle@prim_new admin]$ scp *.ora pdg_new:$ORACLE_HOME/network/admin/
Pfile
将主机上的pfile文件传输到备机
[oracle@prim_new admin]$ scp /home/oracle/pfile.txt pdg_new:/home/oracle/pfile.txt
oracle@pdg_new's password:
pfile.txt
修改pfile.txt:

启动备库到mount
备库：startup pfile=’/home/oracle/pfile.txt’ mount
主机：alter database open;因为刚才是mount状态
alter database set standby database to maximize availability;完成后，在备库上查看状态：
SQL> select name,remote_archive,database_role,guard_status,db_unique_name from v$database;
NAME REMOTE_A DATABASE_ROLE GUARD_S DB_UNIQUE_NAME
