一.2.3  本文简介

 

虽然之前已经多次安装过dg了,但都是基于单实例的,无论是物理还是逻辑的,感觉都非常轻松,没有碰到大的问题,但是最近同事安装dg老是碰到问题,尤其是在执行duplicate命令的时候报错,所以我想还是自己也搭建的试试吧,顺便也写写文档。

 

 

 

一.3  相关知识点扫盲(摘自网络)

【DG】主rac + 备rac dg 部署_rac dg_02 

 

 

Physical Standby使用的是Media Recovery 技术,在数据块级别进行恢复,这种方式没有数据类型的限制,可以保证两个数据库完全一致。 Physical Standby数据库只能在Mount 状态下进行恢复,也可以是打开,但只能已只读方式打开,并且打开时不能执行恢复操作。Logical Standby使用的是Logminer 技术,通过把日志内容还原成SQL 语句,然后SQL引擎执行这些语句,Logminer Standby不支持所有数据类型,可以在视图DBA_LOGSTDBY_UNSUPPORTED 中查看不支持的数据类型,如果使用了这种数据类型,则不能保证数据库完全一致。LogicalStandby数据库可以在恢复的同时进行读写操作

不少未实际接触过dg的初学者可能会下意识以为data guard是一个备份恢复的工具。我要说的是,这种形容不完全错,dg拥有备份的功能,某些情况下它甚至可以与primary数据库完全一模一样,但是它存在的目的并不仅仅是为了恢复数据,应该说它的存在是为了 确保企业数据的高可用性,数据保护以及灾难恢复 ( 注意这个字眼,灾难恢复dg提供全面的服务包括:创建,维护,管理以及监控standby数据库,确保数据安全,管理员可以通过将一些操作转移到standby数据库执行的方式改善数据库性能 ,构建高可用的企业数据库应用环境。

在Data Gurad 环境中,至少有两个数据库,一个处于Open 状态对外提供服务,这个数据库叫作Primary Database。 第二个处于恢复状态,叫作Standby Database。 运行时primary Database 对外提供服务,用户在Primary Database 上进行操作,操作被记录在联机日志和归档日志中,这些日志通过网络传递给Standby Database。 这个日志会在Standby Database 上重演,从而实现Primary Database Standby Database 的数据同步。 
Oracle Data Gurad 对这一过程进一步的优化设计,使得日志的传递,恢复工作更加自动化,智能化,并且提供一系列参数和命令简化了DBA工作。 
如果是可预见因素需要关闭Primary Database,比如软硬件升级,可以把Standby Database 切换为Primary Database 继续对外服务,这样即减少了服务停止时间,并且数据不会丢失。如果异常原因导致Primary Database 不可用,也可以把Standby Database 强制切换为Primary Database继续对外服务,这时数据损失都和配置的数据保护级别有关系。因此Primary Standby 只是一个角色概念,并不固定在某个数据库中。

 

 

问题:RAC DG 有什么区别

RAC, Data Gurad, 高可用性体系中的二种工具,每个工具即可以独立应用,也可以相互配合。 他们各自的侧重点不同,适用场景也不同。

RAC 它的强项在于解决单点故障和负载均衡,因此RAC 方案常用于7*24 的核心系统,但RAC 方案中的数据只有一份,尽管可以通过RAID 等机制可以避免存储故障,但是数据本身是没有冗余的,容易形成单点故障。

Data Gurad 通过冗余数据来提供数据保护,Data Gurad 通过日志同步机制保证冗余数据和主数据之前的同步,这种同步可以是实时,延时,同步,异步多种形式。Data Gurad 常用于异地容灾和小企业的高可用性方案,虽然可以在Standby 机器上执行只读查询,从而分散Primary 数据库的性能压力,但是Data Gurad 决不是性能解决方案。

第二章 实验部分(正式开始搭建)

 

 

 

创建物理备库的方法很多,对于Oracle 11g而言,可以直接从active database来创建,也可以基于10g RMAN备份方式来创建。

该环境中我主要是为了区分dg中各种参数配置的是tnsnamesoracle_siddbname还是db_unique_name,所以设置的值不同,一般情况这4者可以设置成一样的,dgdb_unique_nameoracle_sidtns可以设置成一样的。

 

 

二.2  主库操作

二.2.1  先创建

 

dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbname TESTDG  -sid DGPRI -sysPassword lhr -systemPassword lhr -datafileDestination 'DATA/' -redoLogFileSize 50 -recoveryAreaDestination '/arch' -storageType ASM -asmsnmpPassword lhr  -diskGroupName 'DATA' -responseFile NO_VALUE -characterset ZHS16GBK -nationalCharacterSet AL16UTF16 -sampleSchema true -automaticMemoryManagement true -totalMemory 1024  -nodeinfo ZFXXX3,ZFXXX4

 

注意:sid不能含有下横线,如DG_PRI会报错:

The SID name can only contain alphanumeric characters.

二.2.2.2  为主库添加standby redo log

 

--为主库添加standby redo log,简要描述一下standby redo log的作用 

--实际上就是与主库接收到的重做日志相对应,也就是说备库调用RFS进程将从主库接收到的重做日志按顺序写入到standby logfile 

--在主库创建standby logfile是便于发生角色转换后备用 

--sandby redo log创建原则: 

--a)、确保standby redo log的大小与主库online redo log的大小一致   

--b)、如主库为单实例数据库:standby redo log组数=主库日志组总数+1 

--c)、如果主库是RAC数据库:standby redo log组数=(每线程的日志组数+1)*最大线程数 

--d)、不建议复用standby redo log,避免增加额外的I/O以及延缓重做传输 

 

单实例:

alter database add standby logfile group 4 ('/u01/app/oracle/oradata/oralg/standby_redo04.log') size 50m;

alter database add standby logfile group 5 ('/u01/app/oracle/oradata/oralg/standby_redo05.log') size 50m;

alter database add standby logfile group 6 ('/u01/app/oracle/oradata/oralg/standby_redo06.log') size 50m;

alter database add standby logfile group 7 ('/u01/app/oracle/oradata/oralg/standby_redo07.log') size 50m;

 

rac下:

alter database add standby logfile thread 1 group 5 size 50M ,group 6 size 50M ,group 7 size 50M ;

alter database add standby logfile thread 2 group 8 size 50M ,group 9 size 50M ,group 10 size 50M ;

二.2.2.3  修改主库参数文件 

--使用下面的命令修改主库参数(此时主库应当使用spfile启动参数) 

LOG_ARCHIVE_CONFIG = 'DG_CONFIG ( db_unique_name, db_unique_name, ... )'  主库与备库端采用相同设置。 
LOG_ARCHIVE_DEST_n
 ='SERVICE=。。。。。   SERIVCE: 用于指定备用数据库的TNSNAMES描述符 
db_file_name_convert log_file_name_convert 参数值为路径,可以直接写db_unique_name 如果使用ASM,可以设置为*.db_file_name_convert =('+DATA','+RECOVERY')   

fal_server fal_client 参数值为TNSNAMES描述符

二.3  配置主库和备库的监听 

--为主库和备库配置监听,整个DG的redo传输服务,都依赖于Oracle Net,因此需要为主备库配置监听且需要配置静态监听  

--配置方法多种多样,可用netmgr,netca,以及直接编辑listener.ora 与tnsnames.ora文件 

--下面是配置之后的listener.ora 与tnsnames.ora文件内容 

more $ORACLE_HOME/network/admin/listener.ora

二.3.1  主库

在主库的第一个节点的监听文件中加入如下内容:

LISTENER =

(DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 22.123.124.31)(PORT = 1521))

    )

)

 

SID_LIST_LISTENER =

(SID_LIST =

   (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db)

      (PROGRAM = extproc)

   )

  (SID_DESC =

    (GLOBAL_DBNAME = TESTDG)

    (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db)

    (SID_NAME= DGPRI1)

  )

)

 

第二个节点加入:

LISTENER =

(DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 22.123.124.32)(PORT = 1521))

    )

)

 

SID_LIST_LISTENER =

(SID_LIST =

   (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db)

      (PROGRAM = extproc)

   )

  (SID_DESC =

    (GLOBAL_DBNAME = TESTDG)

    (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db)

    (SID_NAME= DGPRI2)

  )

)

 

以第一个节点为例,其它类似:

[ZFXXX3:oracle]:/oracle>lsnrctl status

 

LSNRCTL for IBM/AIX RISC System/6000: Version 11.2.0.4.0 - Production on 17-FEB-2016 16:50:02

 

Copyright (c) 1991, 2013, Oracle.  All rights reserved.

 

Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))

STATUS of the LISTENER

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

Alias                     LISTENER

Version                   TNSLSNR for IBM/AIX RISC System/6000: Version 11.2.0.4.0 - Production

Start Date                31-DEC-2015 15:02:50

Uptime                    48 days 1 hr. 47 min. 12 sec

Trace Level               off

Security                  ON: Local OS Authentication

SNMP                      OFF

Listener Parameter File   /oracle/app/11.2.0/grid/network/admin/listener.ora

Listener Log File         /oracle/app/grid/diag/tnslsnr/ZFXXX3/listener/alert/log.xml

 

 

将上边所说的内容加入文件:/oracle/app/11.2.0/grid/network/admin/listener.ora ,然后重启监听器,lsnrctl stop , lsnrctl start,需要注意的是rac下是在grid用户下修改监听文件的。

 

 

 

二.3.2  备库

监听配置参考主库的操作:

 

备库第一个节点:

LISTENER =

(DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 22.123.124.64)(PORT = 1521))

    )

)

 

SID_LIST_LISTENER =

(SID_LIST =

  (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db)

      (PROGRAM = extproc)

   )

  (SID_DESC =

    (GLOBAL_DBNAME = TESTDG)

    (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db)

    (SID_NAME= DGPHY1)

  )

)

 

 

备库第二个节点:

LISTENER =

(DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 22.123.124.66)(PORT = 1521))

    )

)

 

SID_LIST_LISTENER =

(SID_LIST =

  (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db)

      (PROGRAM = extproc)

   )

  (SID_DESC =

    (GLOBAL_DBNAME = TESTDG)

    (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db)

    (SID_NAME= DGPHY2)

  )

)

 

二.4  配置主库和备库的tnsname

[ZFXXX3:grid]:/oracle/app/11.2.0/grid/network/admin>exit

[ZFXXX3:root]:/>su - oracle

[ZFXXX3:oracle]:/oracle>cd $ORACLE_HOME/network/admin

[ZFXXX3:oracle]:/oracle/app/oracle/product/11.2.0/db/network/admin>ls

samples       shrept.lst    sqlnet.ora    tnsnames.b    tnsnames.ora

[ZFXXX3:oracle]:/oracle/app/oracle/product/11.2.0/db/network/admin>vi $ORACLE_HOME/network/admin/tnsnames.ora

 

 

 

注意:tns文件是在oracle用户下配置,将主库和备库的一共4个节点的tnsnames.ora文件加入如下内容:

 

TNS_DGPRI =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 22.123.124.31)(PORT = 1521))

    (ADDRESS = (PROTOCOL = TCP)(HOST = 22.123.124.32)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = TESTDG)

    )

  )

 

TNS_DGPHY =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 22.123.124.64)(PORT = 1521))

    (ADDRESS = (PROTOCOL = TCP)(HOST = 22.123.124.66)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = TESTDG)

    )

  )

 

 

4个节点上分别测试:

[ZFXXX1:oracle]:/oracle>tnsping TNS_DGPHY

 

TNS Ping Utility for IBM/AIX RISC System/6000: Version 11.2.0.4.0 - Production on 17-FEB-2016 17:50:00

OK (0 msec)

[ZFXXX1:oracle]:/oracle>

 

 

二.5  配置备库密码文件 

 

--由于要求主库与备库sys使用相同的密码,在此处,我们直接复制了主库的密码文件到备库,将主库第一个节点的密码文件copy到其它3个节点并修改名称,名称为orapw+ORACLE_SID

 

[ZFXXX3:oracle]:/oracle>l $ORACLE_HOME/dbs/orapwDGPRI*

-rw-r-----    1 oracle   dba            1536 Feb 17 11:12 /oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPRI1

[ZFXXX3:oracle]:/oracle>cp /oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPRI1 /oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPRI2

[ZFXXX3:oracle]:/oracle>cp /oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPRI1 /oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPHY1

[ZFXXX3:oracle]:/oracle>cp /oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPRI1 /oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPHY2

[ZFXXX3:oracle]:/oracle>scp /oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPHY1 oracle@22.123.124.64:/oracle/app/oracle/product/11.2.0/db/dbs/orapwDGPHY1

二.6  备库操作

二.6.1  配置备库路径

11g一般创建如下路径,若是asm的话只需要创建 /u01/app/oracle/admin/TESTDGPHY/adump

mkdir -p $ORACLE_BASE/admin/TESTDGPHY/adump

mkdir -p  $ORACLE_BASE/oradata/TESTDGPHY/

mkdir -p  $ORACLE_BASE/oradata/TESTDGPHY/standby_redo/

 

[ZFXXX1:oracle]:/oracle>mkdir -p  $ORACLE_BASE/admin/TESTDGPHY/adump

[ZFXXX1:oracle]:/oracle>

 

第二个节点创建:

[ZFXXX2:oracle]:/oracle>mkdir -p  $ORACLE_BASE/admin/TESTDGPHY/adump

[ZFXXX2:oracle]:/oracle>

 

 

11g如果不创建audit_file_dest的路径会报如下的错误,而10g的话创建的路径比较多,可以查看spfile内容进行创建:

RMAN-04014: startup failed: ORA-09925: Unable to create audit trail file

IBM AIX RISC System/6000 Error: 2: No such file or directory

Additional information: 9925

 

 

 

二.6.2  配置备库pfile文件并启动到nomount状态

我们选择备库的第一个节点作为实施节点:

 

[ZFXXX1:root]:/>su - oracle

[ZFXXX1:oracle]:/oracle>cd $ORACLE_HOME/dbs

[ZFXXX1:oracle]:/oracle/app/oracle/product/11.2.0/db/dbs>l

二.6.3  利用rmanduplicate复制主库文件到备库 

--对于从主库克隆standby有多种方法,而且Oracle 11g支持从ative database直接克隆数据库 

--为主库生成控制文件,注,对于配置standby,不能直接使用copy方式复制控制文件到备库 

 

我们选择备库的第一个节点作为实施节点,脚本需要修改的地方参考前边的说明,懒人可以把TNSdb_unique_name设置成一样的:

 

duplicate target database

for standby nofilenamecheck

from active database

DORECOVER

spfile

set db_unique_name='TESTDGPHY'

set log_archive_dest_1='LOCATION=/arch valid_for=(ALL_LOGFILES,ALL_ROLES) db_unique_name=TESTDGPHY'

set log_archive_dest_2='service=TNS_DGPRI async lgwr register valid_for=(online_logfile,primary_role) db_unique_name=TESTDG'

set standby_file_management='AUTO'

set fal_server='TNS_DGPRI'

set fal_client='TESTDGPHY'

set control_files='+DATA/TESTDGPHY/controlfile/crontal01.ctl','+DATA/TESTDGPHY/controlfile/control02.ctl'

set db_file_name_convert='TESTDG','TESTDGPHY'

set log_file_name_convert='TESTDG','TESTDGPHY'

set memory_target='1024M'

set audit_file_dest='/oracle/app/oracle/admin/TESTDGPHY/adump'

set db_create_file_dest = '+DATA'

set instance_number = '1'

;

 

若主库比较大,也可以多开几个channel来传递,如下脚本:

run {

allocate channel ch001 type disk;

allocate channel ch002 type disk;

allocate channel ch003 type disk;

allocate channel ch004 type disk;

allocate auxiliary channel ch005 type disk;

duplicate target database

for standby nofilenamecheck

from active database

DORECOVER

spfile

set db_unique_name='TESTDGPHY'

set log_archive_dest_1='LOCATION=/arch valid_for=(ALL_LOGFILES,ALL_ROLES) db_unique_name=TESTDGPHY'

set log_archive_dest_2='service=TNS_DGPRI async lgwr register valid_for=(online_logfile,primary_role) db_unique_name=TESTDG'

set standby_file_management='AUTO'

set fal_server='TNS_DGPRI'

set fal_client='TESTDGPHY'

set control_files='+DATA/TESTDGPHY/controlfile/crontal01.ctl','+DATA/TESTDGPHY/controlfile/control02.ctl'

set db_file_name_convert='TESTDG','TESTDGPHY'

set log_file_name_convert='TESTDG','TESTDGPHY'

set memory_target='1024M'

set audit_file_dest='/oracle/app/oracle/admin/TESTDGPHY/adump'

set db_create_file_dest = '+DATA'

set instance_number = '1'

;

release channel ch001;

release channel ch002;

release channel ch003;

release channel ch004;

release channel ch005;

}

需要关注上边蓝色的部分。

 

 

创建spfile文件到磁盘组,并pfile文件中添加spfile的路径

 

SYS@DGPHY1> create spfile='+DATA/TESTDGPHY/PARAMETERFILE/spfiledgphy.ora'  from pfile='/tmp/aa.txt';

 

File created.

 

SYS@DGPHY1> exit

Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,

Data Mining and Real Application Testing options

[ZFXXX1:oracle]:/oracle>echo  "SPFILE='+DATA/TESTDGPHY/PARAMETERFILE/spfiledgphy.ora'" >  $ORACLE_HOME/dbs/initDGPHY1.ora

[ZFXXX1:oracle]:/oracle>more $ORACLE_HOME/dbs/initDGPHY1.ora

SPFILE='+DATA/TESTDGPHY/PARAMETERFILE/spfiledgphy.ora'

[ZFXXX1:oracle]:/oracle>

 

 

在第二个节点中,在pfile文件中添加spfile的路径:

[ZFXXX2:oracle]:/oracle>echo  "SPFILE='+DATA/TESTDGPHY/PARAMETERFILE/spfiledgphy.ora'" >  $ORACLE_HOME/dbs/initDGPHY2.ora

[ZFXXX2:oracle]:/oracle>more $ORACLE_HOME/dbs/initDGPHY2.ora

SPFILE='+DATA/TESTDGPHY/PARAMETERFILE/spfiledgphy.ora'

 

删除原spfile文件/oracle/app/oracle/product/11.2.0/db/dbs/spfileDGPHY1.ora

 

启动2个节点后查看:

SYS@DGPHY1> startup force;

ORACLE instance started.

二.6.5  将备库加入crsctl

srvctl stop database -d TESTDG -o immediate

srvctl status database -d DGPHY

srvctl start database -d TESTDG -o mount

 

 

srvctl add database -d TESTDGPHY -c RAC -o /oracle/app/oracle/product/11.2.0/db -p '+DATA/TESTDGPHY/PARAMETERFILE/spfiledgphy.ora' -r physical_standby -n TESTDG

 

srvctl add instance -d TESTDGPHY -i DGPHY1 -n ZFXXX1

srvctl add instance -d TESTDGPHY -i DGPHY2 -n ZFXXX2

 

srvctl status database -d TESTDGPHY

srvctl start database -d TESTDGPHY

 

srvctl remove  database -d  TESTDGPHY

 

srvctl config database -d TESTDGPHY -a

 

dbca创建的数据库会自动加入crsctl中,但通过rman创建的库不会加入crsctl中,需要手动添加,将备库加入crsctl后可以通过srvctl来管理数据库了。

可以看到数据已经实时同步了,至此,物理备库搭建完成,至于备库的维护操作还有很多内容,参考我的其它blog

二.7  实验总结

实验过程中需要注意的几项内容:

① 主库修改参数一定要加 sid='*'

② 监听必须配置好

③ 执行duplicate命令的时候,如果是rac库需要添加参数:set instance_number = '1',否则报错:

RMAN-03015: error occurred in stored script Memory Script

RMAN-04014: startup failed: ORA-29760: instance_number parameter not specified
