数据库环境oracle 11.1.0.6

操作系统环境 linux redhat update 4 32位

ORACLE_BASE为/u01/app/oracle

ORACLE_HOME为/u01/app/oracle/product/11.1.6/db_1

主库数据文件存放目录/oradata/asm11g/下

备库数据文件存放目录/oradata/standby/下

1.配置主数据库为归档模式和强制使用日志模式

SQL>startup force mount;

SQL>alter database archivelog;

SQL>alter database open;

SQL> ALTER DATABASE FORCE LOGGING;

2.设置主库spfile参数如下:

DB_NAME=asm11g

DB_UNIQUE_NAME=asm11g

LOG_ARCHIVE_CONFIG='DG_CONFIG=(asm11g,standby)'

CONTROL_FILES='/oradata/asm11g/controlfile/control1.ctl'

LOG_ARCHIVE_DEST_1=

'LOCATION=/u01/app/oracle/archivelog

VALID_FOR=(ALL_LOGFILES,ALL_ROLES)

DB_UNIQUE_NAME=asm11g'

LOG_ARCHIVE_DEST_2=

'SERVICE=standby ASYNC

VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)

DB_UNIQUE_NAME=standby'

LOG_ARCHIVE_DEST_STATE_1=ENABLE

LOG_ARCHIVE_DEST_STATE_2=ENABLE

REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE

LOG_ARCHIVE_FORMAT=%t_%s_%r.arc

LOG_ARCHIVE_MAX_PROCESSES=30

3.新建备库存放目录

cd $ORACLE_BASE

CD admin

mkdir standby

cd standby

mkdir adump

mkdir dpdump

mkdir pfile

cd /oradata

mdkir standby

4.备份主库数据文件 用rman工具

rman target /

backup database format '/oradata/%U.bak';

5.在主库生成备库控制文件

SQL>startup force mount;

SQL> ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/oradata/standby/control01.ctl';

SQL> ALTER DATABASE OPEN;

6.从主库创建参数文件用于备库

SQL> CREATE PFILE='/oradata/standby/initstandby.ora' FROM SPFILE;

修改备库参数文件如下 vi initstandby.ora:

DB_NAME=asm11g

DB_UNIQUE_NAME=standby

LOG_ARCHIVE_CONFIG='DG_CONFIG=(asm11g,standby)'

CONTROL_FILES='/oradata/standby/control1.ctl'

DB_FILE_NAME_CONVERT='asm11g','standby'

LOG_FILE_NAME_CONVERT='asm11g','standby'

LOG_ARCHIVE_FORMAT=log%t_%s_%r.arc

LOG_ARCHIVE_DEST_1=

'LOCATION=/oradata/standby/archivelog.

VALID_FOR=(ALL_LOGFILES,ALL_ROLES)

DB_UNIQUE_NAME=standby'

LOG_ARCHIVE_DEST_2=

'SERVICE=asm11g ASYNC

VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)

DB_UNIQUE_NAME=asm11g'

LOG_ARCHIVE_DEST_STATE_1=ENABLE

LOG_ARCHIVE_DEST_STATE_2=ENABLE

REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE

STANDBY_FILE_MANAGEMENT=AUTO

FAL_SERVER=asm11g

FAL_CLIENT=standby

7.备库创建密码文件 注意要和主库密码一致

cd $ORACLE_HOME/dbs

orapwd file=orapwstandby password=abcdefg entries=10 ignorecase=y

8.配置主库和备库的listener 采用静态注册 如下所示:

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = asm11g.localdomain)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

)

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /u01/app/oracle/product/11.1.6/db_1)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_NAME =asm11g)

(ORACLE_HOME = /u01/app/oracle/product/11.1.6/db_1)

(SID_NAME =asm11g)

)

(SID_DESC =

(GLOBAL_NAME =standby)

(ORACLE_HOME = /u01/app/oracle/product/11.1.6/db_1)

(SID_NAME =standby)

)

)

#lsnrctl stop

#lsnrctl start

9.配置tnsnames.ora文件

[oracle@asm11g admin]$ more tnsnames.ora

# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.1.6/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

ASM11G =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = asm11g.localdomain)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = asm11g)

)

)

standby =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = asm11g.localdomain)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME =standby)

)

)

tnsping 验证

[oracle@asm11g admin]$ tnsping asm11g

[oracle@asm11g admin]$ tnsping standby

OK (10 msec)

[oracle@asm11g admin]$

10.启动standby 数据库

export ORACLE_SID=standby

sqlplus / as sysdba

create spfile from pfile='/oradata/standby/initstandby.ora';

startup nomount;

alter database mount standby database;

host

恢复主库的数据文件到备库

rman target /

restore database;

exit;

添加standby logfile 启动到恢复管理模式

idle> alter database add standby logfile '/oradata/standby/redo04.log' size 50M;

Database altered.

Elapsed: 00:00:01.06

idle> alter database add standby logfile '/oradata/standby/redo05.log' size 50M;

Database altered.

Elapsed: 00:00:01.18

idle> alter database add standby logfile '/oradata/standby/redo06.log' size 50M;

Database altered.

Elapsed: 00:00:00.85

idle> recover managed standby database disconnect from session;

Media recovery complete.

..

11.验证归档是否正常传送

主库:

alter system switch logfile;

备库:是否传送过来

SQL> SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME

2> FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;

是否已经apply

SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG

2 ORDER BY SEQUENCE#;

检查主库连到备库的参数文件是否正常

select * from v$archive_dest_status;

在配置完成后发现归档日志不能传送到备库

select * from v$archive_dest_status;

发现log_archive_dest_2的status为error

error报ORA-16191: Primary log shipping client not logged on standby

检查数据库日志也发现下面错误

Error 1017 received logging on to the standby

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

Check that the primary and standby are using a password file

and remote_login_passwordfile is set to SHARED or EXCLUSIVE,

and that the SYS password is same in the password files.

returning error ORA-16191

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

Error 16191 connecting to destination LOG_ARCHIVE_DEST_2 standby host 'standby'

Error 16191 attaching to destination LOG_ARCHIVE_DEST_2 standby host 'standby'

ORA-16191: Primary log shipping client not logged on standby

解决方法:重建主库和备库的密码文件 使密码一致

加上ignorecase参数为y

最后重新启动下主库

再查

select * from v$archive_dest_status;

log_archive_dest_2的status为valid
