• 【测试】手工搭建DG


    前言:(一)准备工作:

    1.数据库要处于归档模式;

    2.监听参数:local_listener 默认值为空--1521

    3.关闭闪回(可能会触发数据库的bug,备库不能开闪回)

    4.如果有外部表,外部表要删除。

    (二)环境描述:

    192.168.206.8    主库    ORA11GR2

    192.168.206.9    备库    SBDB

     

    一,将数据库处于归档模式:

    SQL> alter database archivelog;
    
    Database altered.
    
    SQL> archive log list;
    Database log mode              Archive Mode
    Automatic archival             Enabled
    Archive destination            /u01/app/oracle/product/11.2.0/dbhome_1/dbs/arch
    Oldest online log sequence     5
    Next log sequence to archive   7
    Current log sequence           7

    二,查看本地监听,默认值为空:

    SQL> show parameter local_listener;
    
    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    local_listener                       string

    三,关闪回(可能会触发数据库bug,备库不能开闪回)

     

    查看显示关闭:
    SQL> select flashback_on from v$database;
    
    FLASHBACK_ON
    ------------------
    NO

     

     

    四,生成一个文本参数文件修改参数文件:

    SQL> create pfile from spfile;
    
    File created.
    
    [oracle@host08 ~]$ cd $ORACLE_HOME/dbs
    [oracle@host08 dbs]$ ls
    hc_ORA11GR2.dat  init.ora  initORA11GR2.ora  lkORA11GR2  orapwORA11GR2  spfileORA11GR2.ora
    [oracle@host08 dbs]$ vi initORA11GR2.ora
    
    
    
    (将一下参数加入)
    DB_NAME=ORA11GR2
    DB_UNIQUE_NAME=ORA11GR2
    LOG_ARCHIVE_CONFIG='DG_CONFIG=(ORA11GR2,SBDB)'
    CONTROL_FILES='/u01/app/oracle/oradata/ORA11GR2/control01.ctl','/u01/app/oracle/oradata/ORA11GR2/control02.ctl'
    LOG_ARCHIVE_DEST_1=
     'LOCATION=/u01/arch1/ORA11GR2/
      VALID_FOR=(ALL_LOGFILES,ALL_ROLES)
      DB_UNIQUE_NAME=ORA11GR2'
    LOG_ARCHIVE_DEST_2=
     'SERVICE=SBDB ASYNC
      VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
      DB_UNIQUE_NAME=SBDB'
    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
    FAL_SERVER=SBDB
    DB_FILE_NAME_CONVERT='SBDB','ORA11GR2'
    LOG_FILE_NAME_CONVERT=
     '/u01/app/oracle/oradata/SBDB/','/u01/app/oracle/oradata/ORA11GR2/'
    STANDBY_FILE_MANAGEMENT=AUTO

    创建参数中涉及到的目录:

    [oracle@host08 dbs]$ mkdir -p /u01/app/oracle/admin/ORA11GR2/adump
    [oracle@host08 dbs]$ mkdir -p /u01/app/oracle/oradata/ORA11GR2/
    [oracle@host08 dbs]$ mkdir -p /u01/app/oracle
    [oracle@host08 dbs]$ mkdir -p /u01/app/oracle/oradata/ORA11GR2/
    [oracle@host08 dbs]$ mkdir -p /u01/arch1/ORA11GR2/
    [oracle@host08 dbs]$ mkdir -p /u01/app/oracle/oradata/SBDB/
    [oracle@host08 dbs]$ mkdir -p /u01/app/oracle/oradata/ORA11GR2/

     

     

    五,开启force logging

    SQL> alter database FORCE LOGGING;
    
    Database altered.
    
    SQL> select FORCE_LOGGING from v$database;
    
    FOR
    ---
    YES

     

    六,查看日志文件及大小,并增加standby logfile:

    SQL> select GROUP#,MEMBER from v$logfile;
    
        GROUP# MEMBER
    ---------- --------------------------------------------------
             3 /u01/app/oracle/oradata/ORA11GR2/redo03.log
             2 /u01/app/oracle/oradata/ORA11GR2/redo02.log
             1 /u01/app/oracle/oradata/ORA11GR2/redo01.log
    
    SQL> alter database add standby logfile group 4('/u01/app/oracle/oradata/ORA11GR2/redo401_std.log','/u01/app/oracle/oradata/ORA11GR2/redo402_std.log') size 50M;
    
    Database altered.
    
    SQL> c/4/5
      1* alter database add standby logfile group 5('/u01/app/oracle/oradata/ORA11GR2/redo401_std.log','/u01/app/oracle/oradata/ORA11GR2/redo402_std.log') size 50M
    SQL> c/4/5
      1* alter database add standby logfile group 5('/u01/app/oracle/oradata/ORA11GR2/redo501_std.log','/u01/app/oracle/oradata/ORA11GR2/redo402_std.log') size 50M
    SQL> c/4/5
      1* alter database add standby logfile group 5('/u01/app/oracle/oradata/ORA11GR2/redo501_std.log','/u01/app/oracle/oradata/ORA11GR2/redo502_std.log') size 50M
    SQL> /
    
    Database altered.
    
    SQL> c/5/6
      1* alter database add standby logfile group 6('/u01/app/oracle/oradata/ORA11GR2/redo501_std.log','/u01/app/oracle/oradata/ORA11GR2/redo502_std.log') size 50M
    SQL> c/5/6
      1* alter database add standby logfile group 6('/u01/app/oracle/oradata/ORA11GR2/redo601_std.log','/u01/app/oracle/oradata/ORA11GR2/redo502_std.log') size 50M
    SQL> c/5/6
      1* alter database add standby logfile group 6('/u01/app/oracle/oradata/ORA11GR2/redo601_std.log','/u01/app/oracle/oradata/ORA11GR2/redo602_std.log') size 50M
    SQL> /
    
    Database altered.
    
    SQL> c/6/7
      1* alter database add standby logfile group 7('/u01/app/oracle/oradata/ORA11GR2/redo601_std.log','/u01/app/oracle/oradata/ORA11GR2/redo602_std.log') size 50M
    SQL> c/6/7
      1* alter database add standby logfile group 7('/u01/app/oracle/oradata/ORA11GR2/redo701_std.log','/u01/app/oracle/oradata/ORA11GR2/redo602_std.log') size 50M
    SQL> c/6/7
      1* alter database add standby logfile group 7('/u01/app/oracle/oradata/ORA11GR2/redo701_std.log','/u01/app/oracle/oradata/ORA11GR2/redo702_std.log') size 50M
    SQL> /
    
    Database altered.
    
    SQL> select GROUP#,MEMBER from v$logfile;
    
        GROUP# MEMBER
    ---------- --------------------------------------------------
             3 /u01/app/oracle/oradata/ORA11GR2/redo03.log
             2 /u01/app/oracle/oradata/ORA11GR2/redo02.log
             1 /u01/app/oracle/oradata/ORA11GR2/redo01.log
             4 /u01/app/oracle/oradata/ORA11GR2/redo401_std.log
             4 /u01/app/oracle/oradata/ORA11GR2/redo402_std.log
             5 /u01/app/oracle/oradata/ORA11GR2/redo501_std.log
             5 /u01/app/oracle/oradata/ORA11GR2/redo502_std.log
             6 /u01/app/oracle/oradata/ORA11GR2/redo601_std.log
             6 /u01/app/oracle/oradata/ORA11GR2/redo602_std.log
             7 /u01/app/oracle/oradata/ORA11GR2/redo701_std.log
             7 /u01/app/oracle/oradata/ORA11GR2/redo702_std.log
    
    11 rows selected.

     

    七,将主库参数文件和口令文件传给备库:

    [oracle@host08 dbs]$ ls
    hc_ORA11GR2.dat  init.ora  initORA11GR2.ora  lkORA11GR2  orapwORA11GR2  spfileORA11GR2.ora
    
    
    
    [oracle@host08 dbs]$ scp initORA11GR2.ora orapwORA11GR2 192.168.206.9:/u01/app/oracle/product/11.2.0/dbhome_1/dbs
    The authenticity of host '192.168.206.9 (192.168.206.9)' can't be established.
    RSA key fingerprint is 3b:3d:b7:e2:77:91:2d:27:57:87:96:96:b6:56:d2:1e.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added '192.168.206.9' (RSA) to the list of known hosts.
    oracle@192.168.206.9's password: 
    initORA11GR2.ora                                                                                                                     100% 1610     1.6KB/s   00:00    
    orapwORA11GR2                                                                                                                        100% 1536     1.5KB/s   00:00 

    八,修改备库参数文件:(此时备库的DB_NAME 应该跟主库一致)

     

    DB_NAME=ORA11GR2
    DB_UNIQUE_NAME=SBDB
    LOG_ARCHIVE_CONFIG='DG_CONFIG=(SBDB,ORA11GR2)'
    CONTROL_FILES='/u01/app/oracle/oradata/SBDB/control01.ctl','/u01/app/oracle/oradata/SBDB/control02.ctl'
    LOG_ARCHIVE_DEST_1=
     'LOCATION=/u01/arch1/SBDB/ 
      VALID_FOR=(ALL_LOGFILES,ALL_ROLES)
      DB_UNIQUE_NAME=SBDB'
    LOG_ARCHIVE_DEST_2=
     'SERVICE=ORA11GR2 ASYNC
      VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) 
      DB_UNIQUE_NAME=ORA11GR2'
    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
    FAL_SERVER=ORA11GR2
    DB_FILE_NAME_CONVERT='ORA11GR2','SBDB'
    LOG_FILE_NAME_CONVERT=
     '/u01/app/oracle/oradata/ORA11GR2/','/u01/app/oracle/oradata/SBDB/'
    STANDBY_FILE_MANAGEMENT=AUTO

     

    九,创建参数中涉及到的目录:

    [oracle@host09 dbs]$ mkdir -p /u01/app/oracle/admin/SBDB/adump
    [oracle@host09 dbs]$ mkdir -p /u01/app/oracle/oradata/SBDB/
    [oracle@host09 dbs]$ mkdir -p /u01/app/oracle
    [oracle@host09 dbs]$ mkdir -p /u01/app/oracle/oradata/SBDB/
    [oracle@host09 dbs]$ mkdir -p /u01/arch1/SBDB/ 
    [oracle@host09 dbs]$ mkdir -p /u01/app/oracle/oradata/ORA11GR2/
    [oracle@host09 dbs]$ mkdir -p /u01/app/oracle/oradata/SBDB/

    十,配置网络监听:

    主库:
    ①[oracle@host08 admin]$ vi listener.ora 
    
    # listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
    # Generated by Oracle configuration tools.
    
    LISTENER =
      (DESCRIPTION_LIST =
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = TCP)(HOST = host08)(PORT = 1521))
          (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
        )
      )
    
    ADR_BASE_LISTENER = /u01/app/oracle
    
    
    SID_LIST_LISTENER=
       (SID_LIST=
           (SID_DESC=
              (GLOBAL_DBNAME=ORA11GR2)
              (SID_NAME=ORA11GR2)
              (ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
            )
        )
    
    ②[oracle@host08 admin]$ vi tnsnames.ora 
    
    SBDB=
      (DESCRIPTION=
         (ADDRESS=(PROTOCOL=TCP)(HOST=192.168.206.9)(PORT=1521))
        (CONNECT_DATA=
         (SERVER=DEDICATED)
         (SERVICE_NAME=SBDB)
        )
      )
    ③查看状态并验证是否ping通:
    LSNRCTL> status
    Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host08)(PORT=1521)))
    STATUS of the LISTENER

    十一,复制主库生成备库:

    ①此时将备库起到nmount状态
    SQL> startup nomount
    ORACLE instance started.
    
    Total System Global Area  830930944 bytes
    Fixed Size                  2257800 bytes

    ②根据pfile创建spfile:

    
    
    SQL> create pfile from spfile;
    
    File created.
    
    

     

    
    ③生成备库:
