[terry笔记]GoldenGate_迁移同步_主库零停机

ogg根据scn同步数据，源库零停机时间

本次实验与上次的区别：更加注重细节，几乎包含所有步骤，把我越到的坑都作出了说明。并且同步是由10g向11g进行同步，更加符合升级迁移需求。

如下是主要步骤：

1. 配置好ogg源端的mgr、抓取和传送进程，并启动。

2. 配置好ogg目标端的mgr、复制进程，仅启动mgr。

3. 源端可自由进行交易，此时观察源与目标的trail文件是否都正常。

4. 查询源端此时的scn，并按照参数flashbask_scn进行expdp。

5. 目标端impdp导入。

6. 目标端start replicat xxx,aftercsn xxxxx

 

GoldenGate重要进程介绍：

1、Manager管理进程在两端开启，监控和重启其他进程；分配数据存储和报告错误及事件；

2、Extract进程从日志中抓取并传输到target端事务数据；

3、Server Collector进程在target(接受)端接受数据并写入trail文件；

4、Replicat进程读取trail文件，并应用到traget数据库；

5、trail文件时gg自己抓捕信息的文件，是一个OS文件，存放在./dirdat/下，以X00000命名，N顺序1，2,3…此文件用完可配置参数自动删除。

一、环境准备并安装GoldenGate

1. 数据库准备情况

1) 源服务器

hostname:ogg1

IP地址：192.168.100.133

数据库：10.2.0.5.0 64 bit

SID: super

操作系统版本：redhat5.5 64 bit

ogg版本：ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip

2) 目标服务器

hostname:ogg2

IP地址：192.168.100.130

数据库：11.2.0.4.0 64 bit

SID: test

操作系统版本：redhat5.5 64 bit

ogg版本：ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip

2. 创建用户、下载OGG软件并解压安装

ogg1：

[root@ogg1 ~]# mkdir /ogg
[root@ogg1 ~]# useradd -g oinstall -G dba ggs
[root@ogg1 ~]# passwd ggs
[root@ogg1 ~]# su - ggs
[ggs@ogg1 ~]$ id
uid=1001(ggs) gid=1000(oinstall) groups=1000(oinstall),1001(dba)
[ggs@ogg1 ~]$ exit
logout
[root@ogg1 ~]# chown -R ggs:oinstall /ogg

[root@ogg1 ogg]# unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
[root@ogg1 ogg]# tar xvf fbo_ggs_Linux_x64_ora11g_64bit.tar -C /ogg
[root@ogg1 ogg]# chown -R ggs:oinstall /ogg

ogg2：

[root@ogg2 ~]# useradd -g oinstall -G dba ggs
[root@ogg2 ~]# passwd ggs
[root@ogg2 ~]# mkdir /ogg
[root@ogg2 ~]# chown -R ggs:oinstall /ogg

[root@ogg2 ogg]# unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
[root@ogg2 ogg]# tar xvf fbo_ggs_Linux_x64_ora11g_64bit.tar -C /ogg
[root@ogg2 ogg]# chown -R ggs:oinstall /ogg

3. 准备OGG环境变量

#源服务器、与目标服务器都要配置

$ vi /home/ggs/.bash_profile

#源端ggs增加如下行：

export PATH
export ORACLE_BASE=/u01
export ORACLE_HOME=$ORACLE_BASE/product/10.2.
export ORACLE_SID=super
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/ogg:/usr/local/lib:/usr/X11R6/lib
export LD_LIBRARY_PATH_64=$ORACLE_HOME/lib

$ vi /home/ggs/.bash_profile

#目标端ggs增加如下行：

export PATH
export ORACLE_BASE=/u01
export ORACLE_HOME=$ORACLE_BASE/product/11.2.
export ORACLE_SID=test
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/ogg

4. 配置日志模式

#目标服务器不用配置(非双向)

1) 查看规档与日志模式

sqlplus / as sysdba

select log_mode,supplemental_log_data_min,force_logging from v$database;

LOG_MODE     SUPPLEME FOR
------------ -------- ---
NOARCHIVELOG NO       NO

2) 配置为规档模式

shutdown immediate;
startup mount;
alter database archivelog;
alter database open;
alter system set log_archive_dest_1='location=/u01/archive' scope=both;

3) 配置日志模式(打开强制规档与补充日志模式)

alter database add supplemental log data;
alter database force logging; 

4）查看配置结果：

SQL> select log_mode,supplemental_log_data_min,force_logging from v$database;

LOG_MODE     SUPPLEME FOR
------------ -------- ---
ARCHIVELOG   YES      YES

5. 创建GoldenGate用户帐号

1) 源服务器

su - oracle
sqlplus /nolog
conn / as sysdba;
create tablespace ogg datafile '/u01/oradata/super/ogg.dbf' size 10m autoextend on next 10m;
create user ggs identified by ggs default tablespace ogg temporary tablespace TEMP quota unlimited on ogg;
grant connect,resource to ggs;
grant create session,alter session to ggs;
grant select any dictionary,select any table to ggs;
grant alter any table to ggs;
grant flashback any table to ggs;
grant execute on dbms_flashback to ggs;
或直接grant dba to ggs;

2) 目标服务器

su - oracle
sqlplus /nolog
conn / as sysdba;
create tablespace ogg datafile '/u01/oradata/test/ogg.dbf' size 10m autoextend on next 10m;
create user ggs identified by ggs default tablespace ogg temporary tablespace TEMP quota unlimited on ogg;
grant connect,resource to ggs;
grant create session,alter session to ggs;
grant select any dictionary,select any table to ggs;
grant alter any table to ggs;
grant flashback any table to ggs;
grant execute on dbms_flashback to ggs;
grant insert any table to ggs;
grant delete any table to ggs;
grant update any table to ggs;
或直接grant dba to ggs;

6. 安装GoldenGate软件

(1) 源服务器、与目标服务器都要配置

源服务器因为是10g，ogg存在依赖包的问题：

[root@ogg1 ogg]$ su - ggs
[ggs@ogg1 ogg]$ cd /ogg
[ggs@ogg1 ogg]$ ./ggsci #发现ggsci进不去
./ggsci: error while loading shared libraries: libnnz11.so: cannot open shared object file: No such file or directory 

[ggs@ogg1 ogg]$ ldd ggsci #检查依赖包，发现缺少两个11g的包
        libdl.so.2 => /lib64/libdl.so.2 (0x0000003d9b600000)
        libgglog.so => /ogg/libgglog.so (0x00002b8bd05ca000)
        libggrepo.so => /ogg/libggrepo.so (0x00002b8bd07ff000)
        libdb-5.2.so => /ogg/libdb-5.2.so (0x00002b8bd0954000)

        libxerces-c.so.28 => /ogg/libxerces-c.so.28 (0x00002b8bd226b000)
        libantlr3c.so => /ogg/libantlr3c.so (0x00002b8bd2783000)
        libnnz11.so => not found
        libclntsh.so.11.1 => not found
        libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x0000003dad400000)
        libm.so.6 => /lib64/libm.so.6 (0x0000003d9b200000)
        libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000003daa400000)
        libc.so.6 => /lib64/libc.so.6 (0x0000003d9ae00000)
        /lib64/ld-linux-x86-64.so.2 (0x0000003d9aa00000)

在服务器中找不到11g的包：
[root@ogg1 ogg]# find / -name libnnz11.so
[root@ogg1 ogg]# find / -name libnnz10.so
/u01/product/10.2.0/lib/libnnz10.so
/u01/product/10.2.0/lib32/libnnz10.so

[root@ogg1 ogg]# find / -name libclntsh.so.11.1
[root@ogg1 ogg]# find / -name libclntsh.so.10.1
/u01/product/10.2.0/lib/libclntsh.so.10.1
/u01/product/10.2.0/lib32/libclntsh.so.10.1

此时需要做两个软连接：
[oracle@ogg1 lib]$ ln -s /u01/product/10.2.0/lib/libnnz10.so libnnz11.so
[oracle@ogg1 lib]$ ln -s /u01/product/10.2.0/lib/libclntsh.so.10.1 libclntsh.so.11.1

此时可以源端进入ggsci：

[root@ogg1 ogg]# su - ggs
[ggs@ogg1 ~]$ cd /ogg
[ggs@ogg1 ogg]$ ./ggsci
Oracle GoldenGate Command Interpreter for Oracle

(2) 目标服务器都要配置

[root@ogg2 ogg]# su - ggs
[ggs@ogg2 ~]$ cd /ogg
[ggs@ogg2 ogg]$ ./ggsci

Oracle GoldenGate Command Interpreter for Oracle

GGSCI (ogg2) 1> create subdirs

Creating subdirectories under current directory /ogg
Parameter files                /ogg/dirprm: already exists
Report files                   /ogg/dirrpt: created
Checkpoint files               /ogg/dirchk: created

Temporary files                /ogg/dirtmp: created
Stdout files                   /ogg/dirout: created

(3)此时在源端scott下创建了两张测试表test1与test2（必须有主键）：

SQL> conn scott/tiger
Connected.

SQL> create table test1 (id number);
Table created.

SQL> create table test2 (name varchar2(20));
Table created.

SQL> insert into test1 values (1);
1 row created.

SQL> insert into test1 values (2);
1 row created.

SQL> insert into test1 values (3);
1 row created.

SQL> commit;
Commit complete.

SQL> alter table test1 add constraints pk_test1 primary key(id);
Table altered.

SQL> alter table test2 add constraints pk_test2 primary key(name);
Table altered.

SQL> insert into test2 values('xijinping');
1 row created.

SQL> insert into test2 values('likeqiang');
1 row created.

SQL> insert into test2 values('batman');
1 row created.

SQL> commit;
Commit complete.

---

二、 GoldenGate DML同步源端配置

1. 源MGR进程

1) 编辑mgr程组

edit params mgr

port 7809
dynamicportlist 7800-7899
autorestart extract *,retries 5,waitminutes 2
purgeoldextracts ./dirdat/*,usecheckpoints,minkeepdays 7
lagreporthours 1
laginfominutes 30
lagcriticalminutes 45

说明:

port 指定mgr进程通信端口

dynamicportlist 表示mgr进程可以为源与目的端动态通信指定端口

autorestart extract 表示自动重启extract进程组，每2分钟尝试重启所有进程，重试5次。

配置参数后，重启mgr进程生效

purgeoldextracts xxx，usercheckpoints,minkeepdays x表示trail文件会保留7天，ogg会根据checkpoint删除使用过的trail文件。

lagreporthours 1 每隔1小时检查一次extract和replicat的lag。

laginfominutes 30 如果lag超过规定的值（lagcritical），会报错critical。如果没问题，会每30分钟报告信息。

lagcriticalminutes 45 会每隔45分钟报告critical信息。

2) 启动主管理进程

GGSCI (ogg1) 3> start mgr

Manager started.

GGSCI (ogg1) 4> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING

2. 配置Extract进程组

1)GGSCI (ogg1) 5> edit params test_ext

GGSCI (ogg1) 6> view param test_ext

extract test_ext
dynamicresolution
setenv (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
userid ggs,password ggs
exttrail /ogg/dirdat/te
table scott.*;

2) 添加抽取进程

GGSCI (ogg1) 7> add extract test_ext,tranlog,begin now

EXTRACT added.

3) 添加本地trail文件,源extract进程负责写这部分文件，pump负责把这部分文件传到目标服务器端。

GGSCI (ogg1) 8> add exttrail /ogg/dirdat/te,extract test_ext

EXTTRAIL added.

GGSCI (ogg1) 9> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     STOPPED

EXTRACT     STOPPED     TEST_EXT    00:00:00      00:00:39

说明:

extract eora定义extract进程名字

dynamicresolution

setenv设置环境变量

userid 登录数据库

exttrail指定本地trail文件地址

table 定义同步的表

4) 启动服务

GGSCI (ogg1) 16> start extract test_ext

Sending START request to MANAGER ...

EXTRACT TEST_EXT starting

GGSCI (ogg1) 17> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING

EXTRACT     RUNNING     TEST_EXT    00:03:07      00:00:00

此时观察dirdat目录，可以发现抽取的文件：

[root@ogg1 dirdat]# pwd

/ogg/dirdat

[root@ogg1 dirdat]# ll

总计 4

-rw-rw-rw- 1 ggs oinstall 988 07-08 21:09 te000000

3. 配置Pump进程组

1) 编辑配置文件

edit params test_p

extract test_p
dynamicresolution
passthru
rmthost 192.168.100.130,mgrport 7809,compress
rmttrail /ogg/dirdat/tp
table scott.*;

2) 添加pump进程

GGSCI (ogg1) 21> add extract test_p,exttrailsource /ogg/dirdat/te

EXTRACT added.

3) 添加远程trail文件

GGSCI (ogg1) 22> add rmttrail /ogg/dirdat/tp,extract test_p

RMTTRAIL added.

4) 启动pump进程

GGSCI (ogg1) 23> start extract test_p

Sending START request to MANAGER ...

EXTRACT TEST_P starting

GGSCI (ogg1) 24> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING

EXTRACT     RUNNING     TEST_EXT    00:00:00      00:00:02

EXTRACT     RUNNING     TEST_P      00:00:00      00:00:58

---

三、 GoldenGate DML同步目标端配置

1. 目标端MGR进程

1) 编辑配置文件

GGSCI (ogg2) 1> view param mgr

port 7809
dynamicportlist 7800-7899
purgeoldextracts /ogg/dirdat/*, usecheckpoints, minkeepdays 3

2) 启动

GGSCI (ogg2) 2> start mgr

Manager started.

GGSCI (ogg2) 3> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING

GGSCI (ogg2) 4> exit

此时在目标端的dirdat中可以看到由源端传送过来的trail文件(如果没出现，可以在源端做几个事务即可，做完事务还没出现，那么就是配置有问题，好好检查源端pump和目标端mgr)

[root@ogg2 dirdat]# ll

总计 4

-rw-rw-rw- 1 ggs oinstall 1634 07-08 21:45 tp000000

2. 添加检查表

说明: 当我们在GLOBALS 文件里指定了默认的checkpoint 之后，新的Replicat groups 在创建时会自动使用这个参数，不需要其他指令

1) 目标端编辑全局配置文件

edit params ./GLOBALS

CHECKPOINTTABLE ggs.checkpoint

2）exit #这里需要退出ggsci终端

3) 添加checkpoint表

[ggs@ogg2 ogg]$ ./ggsci

GGSCI (ogg2) 1> dblogin userid ggs,password ggs

Successfully logged into database.

GGSCI (ogg2) 2> add checkpointtable ggs.checkpoint

Successfully created checkpoint table ggs.checkpoint.

切换到数据库下，可以看到checkpoint表

SQL> conn ggs/ggs
Connected.

SQL> select * from tab;

TNAME                          TABTYPE  CLUSTERID
------------------------------ ------- ----------
CHECKPOINT                     TABLE
CHECKPOINT_LOX                 TABLE

3. 配置目标端replicat进程组

1) 编辑配置文件

edit params test_r

replicat test_r
userid ggs,password ggs
assumetargetdefs
reperror default,discard
discardfile /ogg/dirrpt/test_r.desc
dynamicresolution
map scott.*;target scott.*;

2) 添加复制进程，此时不要启动进程

GGSCI (ogg2) 4> add replicat test_r,exttrail /ogg/dirdat/tp,checkpointtable ggs.checkpoint

REPLICAT added.

GGSCI (ogg2) 5> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING

REPLICAT    STOPPED     TEST_R      00:00:00      00:00:14

---

四、查询源scn，将源数据导入目标库

1.源库按照scn导入到目标库

此时源端的数据：

SQL> conn scott/tiger
Connected.

SQL> select * from test1;
        ID
----------
         1
         2
         3

SQL> select * from test2;
NAME
--------------------
batman
likeqiang
superman
xijinping

此时源端的scn
SQL> select current_scn from v$database;

CURRENT_SCN
-----------
     402721

按照scn导出schema：

[oracle@ogg1 dump]$ expdp system/oracle directory=dump dumpfile=scott.dmp schemas=scott flashback_scn=402721

2.验证目标库数据

此时的倒入的数据是源库scn=402721时刻

SQL> conn scott/tiger
已连接。

SQL> select * from test1;
        ID
----------
         1
         2
         3

SQL> select * from test2;
NAME
------------------------------------------------------------
batman
likeqiang
superman
xijinping

3.源库再次做出交易

SQL> insert into test1 values(5);
1 row created.

SQL> commit;
Commit complete.

SQL> insert into test2 values('jackson');
1 row created.

SQL> commit;
Commit complete.

此时原库的trail文件te和目标库的trail文件tp应当都出现了赠长：

[root@ogg1 dirdat]# ll

总计 4

-rw-rw-rw- 1 ggs oinstall 1611 07-08 21:44 te000000

[root@ogg2 dirdat]# ll

总计 4

-rw-rw-rw- 1 ggs oinstall 1634 07-08 21:45 tp000000

4.启动replicat（aftercsn）

GGSCI (ogg2) 9> start replicat test_r,aftercsn 402721
