前言部分

导读和注意事项

各位技术爱好者,看完本文后,你可以掌握如下的技能,也可以学到一些其它你所不知道的知识,~O(∩_∩)O~:

① 主库为rac,备库为rac的物理dg的搭建(重点)

② dbca 静默方式创建rac数据库

③ 如何将数据库加入crsctl管理

④ rac库修改归档路径和归档模式

⑤ 如何添加standby日志

⑥ 简单物理dg的维护

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。

相关知识点扫盲

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 和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 和Standby 只是一个角色概念,并不固定在某个数据库中。

问题:RAC 和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。

实验部分

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 的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tnsnames、oracle_sid、dbname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,dg中db_unique_name、oracle_sid和tns可以设置成一样的。

主库操作

先创建主库

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 LHRAXXTDB3,LHRAXXTDB4
1 2   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 LHRAXXTDB3,LHRAXXTDB4

注意:sid不能含有下横线,如DG_PRI会报错:

The SID name can only contain alphanumeric characters.

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

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

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

主库

在主库的第一个节点的监听文件中加入如下内容:

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 = 22.188.194.31)(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 = 22.188.194.32)(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: [LHRAXXTDB3: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.

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。

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 = 22.188.194.64)(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 = 22.188.194.66)(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) ) )

配置主备库密码文件

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

备库操作

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/ [LHRAXXTDB1:oracle]:/oracle>mkdir -p $ORACLE_BASE/admin/TESTDGPHY/adump [LHRAXXTDB1:oracle]:/oracle>
1 2 3 4 5 6 mkdir -p   $ORACLE_BASE / admin /TESTDGPHY /adump mkdir -p   $ORACLE_BASE /oradata /TESTDGPHY/ mkdir -p   $ORACLE_BASE /oradata /TESTDGPHY /standby_redo/   [LHRAXXTDB1:oracle]:/oracle > mkdir -p   $ORACLE_BASE / admin /TESTDGPHY /adump [LHRAXXTDB1:oracle]:/oracle >

第二个节点创建:

[LHRAXXTDB2:oracle]:/oracle>mkdir -p $ORACLE_BASE/admin/TESTDGPHY/adump [LHRAXXTDB2:oracle]:/oracle>
1 2 [LHRAXXTDB2:oracle]:/oracle > mkdir -p   $ORACLE_BASE / admin /TESTDGPHY /adump [LHRAXXTDB2: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
1 2 3 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

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:

利用rman的duplicate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TNS和db_unique_name设置成一样的:

创建备库spfile并启动备库

由于备库是rac,我们应该修改spfile到磁盘组,然后才能启动rac的2个节点:

需要关注上边蓝色的部分,如下:

创建spfile文件到磁盘组,并在pfile文件中添加spfile的路径:

在第二个节点中,在pfile文件中添加spfile的路径:

[LHRAXXTDB2:oracle]:/oracle>echo "SPFILE='+DATA/TESTDGPHY/PARAMETERFILE/spfiledgphy.ora'" > $ORACLE_HOME/dbs/initDGPHY2.ora [LHRAXXTDB2: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:

将备库加入crsctl中

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中后可以通过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。

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
    1 2 3 RMAN -03015: error occurred in stored script Memory Script   RMAN -04014: startup failed: ORA -29760: instance_number parameter not specified
