两个Oracle 11g 单实例+ASM搭建DG环境

本文主要介绍如何搭建两个单实例+ASM存储环境之间的DG，通过rman duplicate来搭建。实际上和RAC+RAC的DG搭建没有本质区别，如果两个节点的RAC，那么需要通知配置两个节点的配置，如：监听、TNS，参数等。

环境介绍

由于是资源限制，采用的两个单节点的RAC环境(实际上就是单实例+ASM)，具体信息如下：

主机IP 角色 版本 SID DB UNIQUE NAME TNS NAME
192.168.20.100 主 11.2.0.4 lei lei_p lei_primary
192.168.20.101 备 11.2.0.4 lei lei_s lei_standby

搭建环境

搭建单实例+ASM和单实例没有区别，只是通过GI来管理而已。

安装过程略。。。

安装GI时注意，选择standalone，如：
[外链图片转存失败(img-B98OLB1u-1564017095783)(./pictures/1.jpg)]

安装DB和GRID所需的rpm包

##安装常用软件:
yum -y install autoconf automake binutils-devel bison cpp dos2unix ftp gcc gcc-c++ lrzsz python-devel

##安装Oracle必需软件:
yum -y install compat-db compat-db42 compat-db43 compat-gcc-34 compat-gcc-34-c++ compat-libstdc++-33 glibc-* glibc-*.i686 libXpm-*.i686 libXp.so.6 libgcc_s.so.1 ksh libXp libaio-devel numactl numactl-devel unixODBC unixODBC-devel compat-libcap* sysstat* elfutils-libelf-devel

主库修改配置

主要修改主库的相关参数，如：force_logging,归档模式，归档路径等相关参数。

启用归档，启用force_logging

启用归档需要在mount模式下修改，而启用force_logging在线修改即可。

注：只需要在一个节点操作即可。

查看当前归档模式和FORCE_LOGGING状态：

SQL>  select name,log_mode,force_logging from gv$database;

NAME                        LOG_MODE                             FORCE_LOG
--------------------------- ------------------------------------ ---------
LEI                         NOARCHIVELOG                         NO

启用归档：

SQL> shutdown immediate
SQL> startup mount;
SQL> alter database archivelog;

启用force_logging:

SQL> alter database force logging;

检查修改结果：

SQL> select name,log_mode,force_logging from gv$database;

NAME                        LOG_MODE                             FORCE_LOG
--------------------------- ------------------------------------ ---------
LEI                         ARCHIVELOG                           YES

创建standby redo

通常情况下创建和当前redo log一样大小的日志并且组数要多一组。

如下，默认是三组50m大小的redo

SQL> select thread#,group#,bytes/1024/1024 from v$log;

   THREAD#     GROUP# BYTES/1024/1024
---------- ---------- ---------------
         1          1              50
         1          2              50
         1          3              50
         2          4              50
         2          5              50
         2          6              50

查看当前redo存储位置

SQL> col member for a50
SQL> select group#,member from v$logfile;

    GROUP# MEMBER
---------- --------------------------------------------------
         3 +DATA/lei/onlinelog/group_3.266.1319463779
         3 +DATA/lei/onlinelog/group_3.267.1319463779
         2 +DATA/lei/onlinelog/group_2.264.1319463779
         2 +DATA/lei/onlinelog/group_2.265.1319463779
         1 +DATA/lei/onlinelog/group_1.262.1319463777
         1 +DATA/lei/onlinelog/group_1.263.1319463777

所以要创建每个线程四组standby redo,创建单独的目录用于存储standby redo：+DATA/lei/standbylog/

ASMCMD> cd data/lei
ASMCMD> mkdir standbylog
ASMCMD> cd standbylog
ASMCMD> pwd
+data/lei/standbylog

创建standby redo

alter database add standby logfile thread 1 group 7 '+DATA/lei/standbylog/std_redo07.log' size 50m;
alter database add standby logfile thread 1 group 8 '+DATA/lei/standbylog/std_redo08.log' size 50m;
alter database add standby logfile thread 1 group 9 '+DATA/lei/standbylog/std_redo09.log' size 50m;
alter database add standby logfile thread 1 group 10 '+DATA/lei/standbylog/std_redo10.log' size 50m;

#如果是RAC环境，则还需要执行以下SQL
alter database add standby logfile thread 2 group 11 '+DATA/lei/standbylog/std_redo11.log' size 50m;
alter database add standby logfile thread 2 group 12 '+DATA/lei/standbylog/std_redo12.log' size 50m;
alter database add standby logfile thread 2 group 13 '+DATA/lei/standbylog/std_redo13.log' size 50m;
alter database add standby logfile thread 2 group 14 '+DATA/lei/standbylog/std_redo14.log' size 50m;

确认standby redo信息

select group#,sequence#,status, bytes/1024/1024 from v$standby_log;

select group#,member from v$logfile;

修改配置

以下配置，除了只有db_file_name_convert和log_file_name_convert需要重启数据库之外，其他参数均不需要重启。

需要修改的参数如下：

alter system set fal_server='lei_s' sid='*' scope=both;
alter system set fal_client='lei'  sid='*' scope=both;
alter system set db_file_name_convert='+DATA/lei_s/','+DATA/lei/' sid='*' scope=spfile;
alter system set log_file_name_convert='+DATA/lei_s/','+DATA/lei/' sid='*' scope=spfile;
alter system set standby_file_management='auto'  sid='*' scope=both;
alter system set log_archive_config='dg_config=(lei,lei_s)' sid='*' scope=both;
alter system set log_archive_dest_1='location=+DATA/lei/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=lei' sid='*' scope=both;
alter system set log_archive_dest_2='service=lei_standby valid_for=(online_logfiles,primary_role) db_unique_name=lei_s' sid='*' scope=both; #service为TNS NAME
alter system set log_archive_dest_state_1=enable sid='*' scope=both;
alter system set log_archive_dest_state_2=enable sid='*' scope=both;

重启数据库使参数生效。

srvctl stop database -d lei
srvctl start database -d lei

配置静态监听和TNS

注意：listener.ora文件是GIRD_ORACLE下的，而tnsname.ora文件是在ORACLE_HOME下的。

可通过netmgr工具配置，也可以手动修改listener.ora文件。但是效果都是一样，最终的文件内容如下：

# listener.ora Network Configuration File: /u01/app/11.2.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = rac-p)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/grid

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON              # line added by Agent

# 新增的
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
    (GLOBAL_DBNAME = lei)
    (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)    # DB的ORACLE_HOME
    (SID_NAME = lei1)   --第二节点改为lei2
  )
)

重启监听

rac-p-> srvctl stop listener -l LISTENER
rac-p-> srvctl start listener -l LISTENER

rac-p-> lsnrctl status

UNKNOWN表示启用了静态监听。

配置TNS

主备库的TNS文件内容完全相同，配置一个复制即可。

内容如下：

# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

LEI_PRIMARY =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.20.100)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = lei)
    )
  )

LEI_STANDBY =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.20.101)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = lei_s)
    )
  )

拷贝密码文件到备库

随便将一个节点的密码文件拷贝到备库即可。

scp orapwlei1 192.168.20.101:/u01/app/oracle/product/11.2.0/db_1/dbs/orapwlei1
scp orapwlei1 192.168.20.102:/u01/app/oracle/product/11.2.0/db_1/dbs/orapwlei2

至此主库的相关配置就完成了！

备库修改配置

备库主要修改监听、参数文件、TNS文件。

配置静态监听

内容和主库没有什么区别。如下：

# listener.ora Network Configuration File: /u01/app/11.2.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = rac-s)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/grid

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON              # line added by Agent

# 新增的
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
    (GLOBAL_DBNAME = lei_s)
    (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)  # DB的ORACLE_HOME
    (SID_NAME = lei1)   --第二节点改为lei2
  )
)

重启监听。

配置TNS文件

将主库的TNS文件拷贝过来即可

修改pfile文件

从主库创建一个pfile文件

SQL> create pfile='/tmp/lei.ora' from spfile;

File created.

然后修改以下参数即可,仅列出需要修改的参数

*.audit_file_dest='/u01/app/oracle/admin/lei_s/adump'
*.control_files='+DATA/lei_s/controlfile/control01.ctl','+DATA/lei_s/controlfile/control02.ctl'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=lei_sXDB)'
*.db_file_name_convert='+DATA/lei_s/','+DATA/lei/'
*.fal_client='lei_s'
*.fal_server='lei'
*.db_unique_name='lei_s'
*.log_archive_config='dg_config=(racdb,lei_s)'
*.log_archive_dest_1='location=+DATA/lei_s/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=lei_s'
*.log_archive_dest_2='service=lei_primary valid_for=(online_logfiles,primary_role) db_unique_name=lei'
*.log_archive_dest_state_1='ENABLE'
*.log_archive_dest_state_2='ENABLE'
*.log_file_name_convert='+DATA/lei/','+DATA/lei_s/'
*.db_file_name_convert='+DATA/lei/datafile/','+DATA/lei_s/datafile/'

创建目录:

实际上所有pfile文件中出现的目录都需要创建

mkdir -p /u01/app/oracle/admin/lei/adump


rac-s-> asmcmd
ASMCMD> ls
DATA/
ASMCMD> cd data
ASMCMD> ls
ASM/
ASMCMD> mkdir lei_s
ASMCMD> cd lei_s
ASMCMD> mkdir standbylog
ASMCMD> mkdir controlfile
ASMCMD> mkdir spfile
ASMCMD> mkdir archivelog

利用pfile启动到nomount状态

SQL> startup nomount pfile='/tmp/lei_s.ora';

注意：不要提前创建磁盘组中的SPFILE并启动数据库到nomount状态，这样可能会造成后面DUPLICATE报错(ORA-17628)。

RMAN DUPLICATE

如果数据库比较大并且业务不忙或者凌晨时，可以指定多个通道并行处理，如下：

run {
allocate channel channel1 type disk;
allocate channel channel2 type disk;
allocate auxiliary channel stby1 type disk;
duplicate target database for standby from active database
spfile
set audit_file_dest='/u01/app/oracle/admin/lei_s/adump'
set control_files='+DATA/lei_s/controlfile/control01.ctl','+DATA/lei_s/controlfile/control02.ctl'
set dispatchers='(PROTOCOL=TCP) (SERVICE=lei_sXDB)'
set db_file_name_convert='+DATA/lei/datafile/','+DATA/lei_s/datafile/'
set fal_client='lei_s'
set fal_server='lei'
set db_unique_name='lei_s'
set log_archive_config='dg_config=(lei,lei_s)'
set log_archive_dest_1='location=+DATA/lei_s/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=lei_s'
set log_archive_dest_2='service=lei_primary valid_for=(online_logfiles,primary_role) db_unique_name=lei'
set log_archive_dest_state_1='ENABLE'
set log_archive_dest_state_2='ENABLE'
set log_file_name_convert='+DATA/lei/','+DATA/lei_s/'
nofilenamecheck;
release channel channel1;
release channel channel2;
release channel stby1;
}

输出信息如下：

rac-s-> rman target sys/oracle@lei_primary auxiliary sys/oracle@lei_standby

创建SPFILE

生成新的pfile文件

SQL> create pfile='/tmp/lei_s.ora' from spfile;

File created.

文件内容如下：

SQL> !more '/tmp/lei_s.ora'

通过新的pfile文件，创建新的SPFILE文件

SQL> create spfile='+DATA/lei_s/parameterfile/spfilelei_s.ora' from pfile='/tmp/lei_s.ora';

File created.

编辑本地pfile文件指定到磁盘组中SPFILE

rac-s-> cat initlei.ora
SPFILE='+DATA/lei_s/parameterfile/spfilelei_s.ora'

删除本地的SPFILE

[root@rac-s dbs]# rm /u01/app/oracle/product/11.2.0/db_1/dbs/spfilelei.ora
rm: remove regular file `spfilelei.ora'? yes

使用SPFILE启动数据库

SQL> startup

验证

启动MRP

SQL> alter database recover managed standby database disconnect from session;

Database altered.

SQL> selEct process,status from v$managed_standby;
