数据库迁移方案之DG方式迁移

一：环境信息

1)主库（单实例）

主机平台：AIX6.1

数据库版本：11.2.0.3（psu5）

2)备库（部署了crs）

主机平台：AIX6.1

数据库版本：11.2.0.3（psu5）

二：方案背景

  由于业务量增加，数据库需要由单实例，改成两节点rac。为了减少停机时间，采用DG方式迁移。

三迁移方案：

1.检查数据库是否支持Data Guard（只有企业版才支持DG）

SQL> select * from v$option where parameter = 'Managed Standby';
PARAMETER                                                        VALUE
---------------------------------------------------------------- ----------------------------------------------------------------
Managed Standby                                                  TRUE

2.修改主库为归档模式及force logging状态
1）

SQL> alter database force logging;
Database altered.

2）
SQL> archive log list;
如果未开归档，开启归档模式

alter system set log_archive_dest_2='location=/archlog/egap';
alter system set log_archive_format='egap_%t_%s_%r.arch' scope=spfile; --静态参数，重启后生效
shutdown immediate;
startup mount;
alter database archivelog;
alter database open;
archive log list;

3.创建备库pfile文件
在主库上创建pfile，修改，并添加DG备库所有参数，然后传至备库

SQL> create pfile='/data01/pfileegap' from spfile;

1）备库需要添加的参数
DB_UNIQUE_NAME;LOG_ARCHIVE_DEST_1;FAL_SERVER;FAL_CLIENT; STANDBY_FILE_MANAGEMENT=AUTO;DB_FILE_NAME_CONVERT;LOG_FILE_NAME_CONVERT
2）根据pfile中涉及到路径需要提前在备库主机上建好（如果主备库路径不一致要修改）
如主库*.audit_file_dest='/apps/oracle/admin/egap/adump'
我们在备库需要建 mkdir -p /apps/oracle/admin/egap/adump
cd /apps/oracle/admin
chown -R oracle:oinstall egap
chmod -R 775 egap

改变前参数文件

*.__db_cache_size=27648851968
*.__java_pool_size=67108864
*.__large_pool_size=67108864
*.__oracle_base='/apps/oracle'#ORACLE_BASE set from environment

*.__shared_io_pool_size=0
*.__shared_pool_size=2952790016
*.__streams_pool_size=0
*.audit_file_dest='/apps/oracle/admin/egap/adump'
*.audit_trail='db'
*.compatible='11.2.0.0.0'
*.control_files='/data01/egap/control01.ctl','/data01/egap/control02.ctl'
*.db_block_size=8192
*.db_domain=''
*.db_name='egap'
*.diagnostic_dest='/apps/oracle'
*.log_archive_dest_1='location=/archlog/egap'
*.log_archive_format='egap_%t_%s_%r.arch'
*.open_cursors=300
*.pga_aggregate_target=10307502080
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.sga_target=30922506240
*.undo_tablespace='UNDOTBS1'

改变后参数文件

egap1.__oracle_base='/apps/oracle'#ORACLE_BASE set from environment
*._gc_policy_time=0
*._undo_autotune=FALSE
*.audit_trail='NONE'
*.archive_lag_target=1800
*.audit_file_dest='/apps/oracle/admin/egapdb/adump'
*.compatible='11.2.0.0.0'
*.control_files='/data01/egapdb/controlfile/control01.ctl','/data02/egapdb/controlfile/control02.ctl'
*.db_block_size=8192
*.db_cache_size=12884901888
*.db_create_file_dest='/data01/egapdb/datafile'
*.db_domain=''
*.db_name='egap'
*.diagnostic_dest='/apps/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=egapXDB)'
*.large_pool_size=1073741824
*.open_cursors=1000
*.pga_aggregate_target=21474836480
*.processes=4000
*.remote_login_passwordfile='EXCLUSIVE'
*.sessions=3305
*.sga_max_size=34359738368
*.sga_target=34359738368
*.shared_pool_size=4294967296
*.undo_retention=5400
*.undo_tablespace='UNDOTBS1'
egapdb1.log_archive_dest_1='location=/archlog/egapdb1'
*.log_archive_dest_2='SERVICE=egap LGWR ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=egap'
*.log_archive_format='egapdb_%t_%s_%r.arch'
*.DB_UNIQUE_NAME=egapdb
*.FAL_SERVER=egap
egapdb1.FAL_CLIENT=egapdb1
egapdb2.FAL_CLIENT=egapdb2
*.STANDBY_FILE_MANAGEMENT=AUTO
*.DB_FILE_NAME_CONVERT='+DATA3/egap/datafile','/data01/egapdb/datafile','+DATA4/egap/datafile','/data02/egapdb/datafile','+DATA3/egap/tempfile','/data01/egapdb/tempfile','+DATA4/egap/tempfile','/data02/egapdb/tempfile'
*.LOG_FILE_NAME_CONVERT='+DATA3/egap/onlinelog','/data01/egapdb/onlinelog','+FRA3/egap/onlinelog','/data02/egapdb/onlinelog'
*.LOG_ARCHIVE_CONFIG='DG_CONFIG=(egap,egapdb)'

##注意db_file_name_convert和log_file_name_convert参数指定的路径要存在

##关闭数据库审计（audit_trail='NONE'），sga,pga适当加大

4）根据修改后的pfile创建备库spfile

export ORACLE_SID=egapdb1
sqlplus / as sysdba
create spfile from pfile;

--使用新生成的spfile检查是否能够成功启动实例

4.生成备库的密码文件
scp主库密码文件到备库，并改名
如果主库没有密码文件，需要新建

orapwd file=/oracle/app/oracle/product/v11.2.0.3/db_1/dbs/orapwegap password=oracle  entries=5 ignorecase=y

--主库密码文件传到备库以后要重启备库

5.配置主备库监听及net服务
1）listener
--主库
一般建库后都会配置监听我们无需再配置
--备库（因为安装了cluster，所以用的是cluster的监听）
lsnrctl status 查看监听文件位置，并在监听文件中加入如下类容

LISTENER_SCAN3=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN3))))                # line added by Agent
LISTENER_SCAN2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN2))))                # line added by Agent
#LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))))           # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1))))                # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON                # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON              # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN2=ON                # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN3=ON                # line added by Agent
--注意集群安装完毕以后，上面部分内容在监听中已经存在
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /apps/oracle/product/11.2.0.3/db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(ORACLE_HOME = /apps/oracle/product/11.2.0.3/db_1)
(SID_NAME = egapdb1)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.96.1)(PORT = 1521)(IP = FIRST))
)
)

2）tns
主备库tnsnames.ora文件中加入如下部分

primary =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.96.16)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = egap)
)
)
standby1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.96.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = egapdb1)
)
)
standby2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.96.2)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = egapdb2)
)
)

--DG搭建后要主备切换并添加实例

6. 测试网络连接
1）查看监听状态是否正常
lsnrctl status
2) 测试连接串是否能正常连接到指定数据库

tnsping egap
tnsping egapdb1
tnsping egapdb2
sqlplus sys/oracle@egap as sysdba
sqlplus sys/oracle@egapdb1 as sysdba
sqlplus sys/oracle@egapdb2 as sysdba

7. 复制备库
有两种1:rman在线复制 2:rman备份异机恢复
方法1：rman在线复制（不需要备份主库）
此种方式仅适用于ORACLE 11G，可以自动备份datafile,control等文件到备库，在复制过程主库仍可正常运行，但复制过程时间较长，会占用一定的网络资源。
1）将备库启动到nomount状态
export ORACLE_SID=egapdb1
sqlplus / as sysdba
startup nomount;
2)在备库上执行如下命令

rman target sys/oracle@primary auxiliary sys/oracle@standby1 nocatalog
duplicate target database for standby from active database nofilenamecheck;

--如果主备库文件路径不变，要加nofilenamecheck。登陆时加nocatalog否则会报如下错误：

PLS-00201: identifier 'DBMS_RCVCAT.GETDBID' must be declared

8. 添加standby log
--为了日后切换，建议为主库也添加standby log
--注意stnadby log的大小（同主库redolog相同大小）
--注意添加合适数量的standby log

alter database add standby logfile thread 1
GROUP 7('/data01/egapdb/stand07.log') SIZE 50M,
GROUP 8('/data01/egapdb/stand08.log') SIZE 50M,
GROUP 9('/data01/egapdb/stand09.log') SIZE 50M,
GROUP 10('/data01/egapdb/stand10.log') SIZE 50M,
GROUP 11('/data01/egapdb/stand11.log') SIZE 50M,
GROUP 12('/data01/egapdb/stand12.log') SIZE 50M,
GROUP 13('/data01/egapdb/stand13.log') SIZE 50M;
ALTER DATABASE ADD STANDBY LOGFILE THREAD 2 group 3('/oracle/dbs/log1c.rdo','/oracle/dbs/log2c.rdo') SIZE 500M;

SELECT GROUP#,THREAD#,SEQUENCE#,ARCHIVED,STATUS FROM V$STANDBY_LOG;
检查是否成功创建

standy log 的推荐数目为=（每个线程的日志文件的最大数目＋1）×线程最大数目

9.配置主库DG参数
主库需要配置的参数为DB_UNIQUE_NAME;LOG_ARCHIVE_CONFIG;LOG_ARCHIVE_DEST_2;REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
--为了方便以后切主库也应该添加备库所需要的参数

*.DB_UNIQUE_NAME=egap
*.FAL_SERVER=standby1
*.FAL_CLIENT=primary
*.STANDBY_FILE_MANAGEMENT=AUTO
*.DB_FILE_NAME_CONVERT='/data01/egapdb','/data01/egap'
*.LOG_FILE_NAME_CONVERT='/data01/egapdb','/data01/egap'
*.LOG_ARCHIVE_CONFIG='DG_CONFIG=(egap,egapdb)'
*.log_archive_dest_1='location=/archlog/egap'
*.log_archive_dest_2='SERVICE=standby1 LGWR ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=egapdb'
alter system set fal_server='standby1';
alter system set fal_client='primary';
alter system set standby_file_management=auto;
alter system set db_file_name_convert='/data01/egapdb','/data01/egap' scope=spfile;
alter system set log_file_name_convert='/data01/egapdb','/data01/egap' scope=spfile;
alter system set log_archive_config='DG_CONFIG=(egap,egapdb)';
alter system set log_archive_dest_2='SERVICE=standby1 LGWR ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=egapdb';

10.在备库上启动恢复
启动恢复

alter database recover managed standby database using current logfile disconnect;
alter database recover managed standby database cancel;

--主库切换日志，观察DG能否正常应用日志
1）在备库查看 data guard 为哪种日志接受方式，以及当前被应用的日志

SQL> select process,client_process,sequence#,status from v$managed_standby;
PROCESS   CLIENT_P  SEQUENCE# STATUS
--------- -------- ---------- ------------
ARCH      ARCH            132 CLOSING
ARCH      ARCH            131 CLOSING
ARCH      ARCH              0 CONNECTED
ARCH      ARCH            133 CLOSING
MRP0      N/A             134 APPLYING_LOG
RFS       ARCH              0 IDLE
RFS       LGWR            134 IDLE
RFS       UNKNOWN           0 IDLE

--rfs进程接受的是lgwr日志，说明主库用的是lgwr进程传输日志。mrp0进程存在说明此时已启动恢复管理

2）在备库查看新的归档日志有没有正常传输过来，并被应用

SQL> select THREAD#,SEQUENCE#,ARCHIVED,APPLIED,DELETED,STATUS from v$archived_log order by 1,2;

3）查看主备库的alert日志，是否正常
4）备库查看日志应用延时

alter session set nls_date_format='yyyy-mm-dd hh24:mi:ss';
select name,value from v$dataguard_stats where name in ('apply lag','apply finish time');

11.添加实例

1.oracle DG主备切换（switchover）
--切换前检查主备库参数，及standbylog是否配置（如下参数在主备库都需配置）

*.DB_UNIQUE_NAME=egap
*.FAL_SERVER=standby1
*.FAL_CLIENT=primary
*.STANDBY_FILE_MANAGEMENT=AUTO
*.DB_FILE_NAME_CONVERT='/data01/egapdb','/data01/egap'
*.LOG_FILE_NAME_CONVERT='/data01/egapdb','/data01/egap'
*.LOG_ARCHIVE_CONFIG='DG_CONFIG=(egap,egapdb)'
*.log_archive_dest_1='location=/archlog/egap'
*.log_archive_dest_2='SERVICE=standby1 LGWR ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=egapdb'

1）主库

--查看是否可以切换为备库

select database_role,switchover_status from v$database;
注：当SWITCHOVER_STATUS的值为TO STANDBY or SESSIONS ACTIVE的时候表示主库可以支持SWITCHOVER.
alter database commit to switchover to physical standby;
shutdown immediate;
startup nomount;
alter database mount standby database;
alter database recover managed standby database using current logfile disconnect;

2)备库

select database_role,switchover_status from v$database;
注：当SWITCHOVER_STATUS的值为TO PRIMARY or SESSIONS ACTIVE的时候表示备库可以支持SWITCHOVER（在主库执行完commit后会变成to primary
而在主库没有执行之前是not allowed状态）
alter database commit to switchover to primary;

12.配置cluster listener（主要是配置第二个节点的listener）
具体方法见DG实施方案的第五步

3.创建集群参数文件

1）create pfile from spfile;(在转换后的主库上)
修改pfile，并添加rac需要的参数

*.cluster_database = TRUE
*.cluster_database_instances = 2
*.undo_management=AUTO
<SID1>.undo_tablespace=undotbs (undo tablespace which already exists)
<SID1>.instance_name=<SID1>
<SID1>.instance_number=1
<SID1>.thread=1
<SID1>.local_listener=<LISTENERNAME>_<HOSTNAME1>
<SID2>.instance_name=<SID2>
<SID2>.instance_number=2
<SID2>.local_listener=<LISTENERNAME>_<HOSTNAME2>
<SID2>.thread=2
<SID2>.undo_tablespace=UNDOTBS2
<SID2>.cluster_database = TRUE
<SID2>.cluster_database_instances = 2

修改后参数文件如下：

--注意参数文件中定义的路径要在第二个节点提前建立

egapdb1.__oracle_base='/apps/oracle'#ORACLE_BASE set from environment
egapdb2.__oracle_base='/apps/oracle'#ORACLE_BASE set from environment
*.audit_file_dest='/apps/oracle/admin/egapdb/adump'
*.compatible='11.2.0.0.0'
*.control_files='/data01/egapdb/controlfile/control01.ctl','/data02/egapdb/controlfile/control02.ctl'
*.db_block_size=8192
*.db_domain=''
*.db_name='egap'
*.db_unique_name='egapdb'
*.diagnostic_dest='/apps/oracle'
egapdb1.fal_client='egapdb1'
egapdb2.fal_client='egapdb2'
*.fal_server='egap'
*.log_archive_config='DG_CONFIG=(egap,egapdb)'
egapdb1.log_archive_dest_1='location=/archlog/egapdb1'
egapdb2.log_archive_dest_1='location=/archlog/egapdb2'
*.log_archive_dest_2='SERVICE=egap LGWR ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=egap'
*.log_archive_format='egapdb%t_%s_%r.arc'
*.DB_FILE_NAME_CONVERT='+DATA3/egap/datafile','/data01/egapdb/datafile','+DATA4/egap/datafile','/data02/egapdb/datafile','+DATA3/egap/tempfile','/data01/egapdb/tempfile','+DATA4/egap/tempfile','/data02/egapdb/tempfile'
*.LOG_FILE_NAME_CONVERT='+DATA3/egap/onlinelog','/data01/egapdb/onlinelog','+FRA3/egap/onlinelog','/data02/egapdb/onlinelog'
*._gc_policy_time=0
*._undo_autotune=FALSE
*.audit_trail='NONE'
*.archive_lag_target=1800
*.db_files=1000
*.db_cache_size=24G
*.large_pool_size=512M
*.shared_pool_size=4294967296
*.java_pool_size=150M
*.undo_retention=5400
*.open_cursors=1000
*.pga_aggregate_target=21474836480
*.processes=4000
*.sessions=3305
*.remote_login_passwordfile='EXCLUSIVE'
*.sga_max_size=34359738368
*.sga_target=34359738368
*.standby_file_management='AUTO'
*.undo_tablespace='UNDOTBS1'
*.cluster_database = TRUE
*.cluster_database_instances = 2
*.undo_management=AUTO
egapdb1.undo_tablespace='UNDOTBS1'
egapdb1.instance_name=egapdb1
egapdb1.instance_number=1
egapdb1.thread=1
egapdb1.local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.96.3)(PORT=1521))))'
egapdb2.instance_name=egapdb2
egapdb2.instance_number=2
egapdb2.local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.96.4)(PORT=1521))))'
egapdb2.thread=2
egapdb2.undo_tablespace='UNDOTBS2'

2）.修改备库fal_server

alter system set fal_server='standby1','standby2';

--可以在一开始就配置，此处就不必修改

3)创建新的spfile（注意建在共享路径下）

create spfile='/data01/egapdb/spfileegapdb.ora' from pfile='/apps/oracle/product/11.2.0.3/db_1/dbs/initegapdb1.ora';

4)在两个节点的写入如下信息（并删除$ORACLE_HOME/dbs目录下的spfile文件）
SPFILE='/data01/egapdb/spfileegap.ora'

13.生成第二个节点的密码文件
传第老库的密码文件到第二个节点，并改名
scp orapwegap oracle@egapdb2:$ORACLE_HOME/dbs
mv orapwegap orapwegapdb2

14.重启主库使修改的参数生效
1)停主库前，先停掉备库的日志应用
alter database recover managed standby database cancel;
2)停主库
shutdown immediate;
3）startup;
--查看rac相关参数是否生效，tail -f 主备库的alert日志，观察是否有报错，DG是否正常
show parameter cluster;

15.添加其他节点的redo及undo
1)redo

alter database
add logfile thread 2
group 4 ('/data01/egapdb/redo04.log') size 50M,
group 5 ('/data01/egapdb/redo05.log') size 50M,
group 6 ('/data01/egapdb/redo06.log') size 50M;
alter database enable public thread 2;

2)undo

create undo tablespace UNDOTBS2 datafile '/data03/egapdb/undotbs2_03.dbf' size 30G,'/data02/egapdb/undotbs2_02.dbf' size 30G,'/data01/egapdb/undotbs2_01.dbf' size 30G;
alter system set undo_tablespace='undotbs2' sid='egapdb2';--如果参数文件中已修改则可以省略此步

16.在备库添加第二个实例的standby log（不建好像也可以）

17.在备库设置db_recovery_file_dest，db_recovery_file_dest_size参数
--如果不设该参数，备库会报错（主库添加第二个实例日志，在备库应用会报错）
OpenVMS: Error Creating Redo Logs In Standby Database ORA-01264: Unable to create logfile file name (Doc ID 1376892.1)

 

8.在第二个节点打开数据库
--tail -f 主备库alert日志，查看是否有报错，DG是否正常
export ORACLE_SID=egapdb2
sqlplus / as sysdba
startup

 

19.向crs中注册资源
1)查看注册前集群中资源

grid@egapdb2:/home/grid$ crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------

ora.scan2.vip  ora....ip.type ONLINE    ONLINE    egapdb2
ora.scan3.vip  ora....ip.type ONLINE    ONLINE    egapdb2

 

2)注册(在任意一个节点添加即可)

srvctl add database -d <db_unique_name> -o <ORACLE_HOME path> -p <spfile location and name>
srvctl add instance -d <db_unique_name> -i <instance 1 name> -n <node 1 name >
srvctl add instance -d <db_unique_name> -i <instance 2 name> -n <node 2 name >

 

--如果用的是asm的话还需要添加数据库实例同asm实例的对应关系

srvctl modify instance -d <db_unique_name> -i <SID1> -s <+ASM1>
srvctl modify instance -d <db_unique_name> -i <SID2> -s <+ASM2>

 

3)查看注册后的集群资源

grid@egapdb2:/home/grid$ crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
