?? ?Stdout files?????????????????? /opt/app/ggs/11.2/dirout: created


?? ?GGSCI (dg1) 2>


?? ?4.2 建立用戶,并賦權限：
?? ?主庫：
?? ??? ?SQL> create tablespace ggs_tbs datafile '/opt/app/oracle/oradata/DB1/ggs_tbs01.dbf' size 50m;

?? ??? ?SQL> create user ggs identified by ggs default tablespace ggs_tbs;
?? ??? ?User created.
?? ??? ?SQL> grant create session,alter session to ggs;

?? ??? ?Grant succeeded.

?? ??? ?SQL> grant execute on utl_file to ggs;

?? ??? ?Grant succeeded.

?? ??? ?SQL> grant select any dictionary, select any table to ggs;

?? ??? ?SQL> grant alter any table to ggs;

?? ??? ?Grant succeeded.

?? ??? ?SQL> grant flashback any table to ggs;

?? ??? ?Grant succeeded.

?? ??? ?SQL> grant select any transaction to ggs;

?? ??? ?Grant succeeded.

?? ??? ?SQL> grant sysdba to ggs;

?? ??? ?Grant succeeded.

?? ??? ?SQL> grant create table,insert any table,lock any table to ggs;

?? ??? ?Grant succeeded.

?? ??? ?SQL> grant execute on dbms_flashback to ggs;

?? ??? ?Grant succeeded.

?? ?4.3 源、目標庫打開輔助日志

?? ?SQL> alter database force logging;
?? ?alter database force logging
?? ?*
?? ?ERROR at line 1:
?? ?ORA-12920: database is already in force logging mode


?? ?SQL> alter database add supplemental log data;

?? ?Database altered.

?? ?SQL> select supplemental_log_data_min from v$database;

?? ?SUPPLEMENTAL_LOG_DATA_MI
?? ?------------------------
?? ?YES


?? ?4.4 源庫支持sequence

?? ?在源庫、目標庫上執行：
?? ?GGSCI (dg2) 2> edit params ./globals
?? ?在統計模式下輸入并保存：ggschema ggs

?? ?在SQLPLUS 下去運行：
?? ?sql>?@sequence.sql?根據提示輸入：gg


?? ?4.5?支持ddl復制

?? ? 4.5.1?主庫配置
?? ?cd?/ggs/11.2
?? ?sqlplus?/?as?sysdba
?? ?sql>?alter system set recyclebin=off deferred scope=both;??#必須，針對ddl復制
?? ?sql>?@marker_setup.sql?prompt:?ggs
?? ?sql>?@ddl_setup.sql?prompt:?ggs
?? ?sql>?@role_setup.sql
?? ?sql>?grant?GGS_GGSUSER_ROLE?to?ggs;
?? ?SQL>?@ddl_enable.sql
?? ?10g需要安裝dbms_share_pool包：
?? ?sql>?@?/rdbms/admin/dbmspool.sql?sql>?@ddl_pin?ggs;


?? ?4.6 配置MANAGER
?? ?主庫、目標庫配置：
?? ?[oracle@dg1 11.2]$ ./ggsci

5 配置目標端服務器

?? ? 5.1 配置MYSQL SERVER
?? ?# mysql -u root -p password '123456'
?? ?Enter password:
?? ?mysqladmin: connect to server at 'localhost' failed
?? ?error: 'Access denied for user 'root'@'localhost' (using password: YES)'
?? ?

?? ?修改MYSQL 密碼 操作如下：

?? ?# /etc/init.d/mysql stop
?? ?# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
?? ?# mysql -u root mysql
?? ?mysql> UPDATE user SET Password=PASSWORD('123456') where USER='root' and host='root' or host='localhost';//把空的用戶密碼都修改成非空的密碼就行了。
?? ?mysql> FLUSH PRIVILEGES;
?? ?mysql> quit # /etc/init.d/mysqld restart
?? ?# mysql -uroot -p
?? ?Enter password: <輸入新設的密碼123456>
?? ?
?? ?MySql5.6操作時報錯：You must SET PASSWORD before executing this statement解決
?? ?mysql>? SET PASSWORD = PASSWORD('123456');

?? ?Query OK, 0 rows affected (0.03 sec)
?? ? update user set password=password('123456') where user='root' and host='root' or host='localhost';

?? ?mysql> create database hr;
?? ?Query OK, 1 row affected (0.01 sec)

?? ?mysql> show databases;
?? ?+--------------------+
?? ?| Database?????????? |
?? ?+--------------------+
?? ?| information_schema |
?? ?| hr???????????????? |
?? ?| mysql????????????? |
?? ?| performance_schema |
?? ?| test?????????????? |
?? ?+--------------------+
?? ?5 rows in set (0.00 sec)

?? ?mysql>


?? ? 5.2 配置目標端
?? ?GGSCI (ractdg3) 9> create subdirs

?? ?Creating subdirectories under current directory /opt/app/ggs/11.2

?? ?Parameter files??????????????? /opt/app/ggs/11.2/dirprm: already exists
?? ?Report files?????????????????? /opt/app/ggs/11.2/dirrpt: created
?? ?Checkpoint files?????????????? /opt/app/ggs/11.2/dirchk: created
?? ?Process status files?????????? /opt/app/ggs/11.2/dirpcs: created
?? ?SQL script files?????????????? /opt/app/ggs/11.2/dirsql: created
?? ?Database definitions files???? /opt/app/ggs/11.2/dirdef: created
?? ?Extract data files???????????? /opt/app/ggs/11.2/dirdat: created
?? ?Temporary files??????????????? /opt/app/ggs/11.2/dirtmp: created
?? ?Stdout files?????????????????? /opt/app/ggs/11.2/dirout: created



?? ?GGSCI (ractdg3) 5> edit params mgr


?? ?GGSCI (ractdg3) 10> view params mgr


?? ??? ?Port 7809
?? ??? ?--DYNAMICPORTLIST 7840-7939
?? ??? ?--AUTOSTART ER *
?? ??? ?--AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3
?? ??? ?--PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3
?? ??? ?--LAGREPORTHOURS 1
?? ??? ?--LAGINFOMINUTES 30
?? ??? ?--LAGCRITICALMINUTES 45

?? ?GGSCI (ractdg3) 10> edit param globals

?? ?GGSCI (ractdg3) 11> view param globals

?? ?checkpointtable hr.checkpoint


?? ?GGSCI (ractdg3) 12>


?? ?5.3創建checkpoint表
?? ?ggsci>dblogin sourcedb hr userid root

?? ?(這里糾結了很久，MYSQL 登錄總是報錯：ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
?? ?vi /usr/my.cnf
?? ?添加以下內容后
?? ?socket =/tmp/mysql.sock
?? ?
?? ?在ggsci 登錄 沒有問題了，但在LINUX下，登錄又報ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
?? ?在LINUX下登錄，只好先指定 mysql -u root -p -S? '/tmp/mysql.sock'
?? ?進行登錄，后面再另行解決。
?? ?)

?? ?ggsci>add checkpointtable hr.checkpoint
?? ?ggsci>?edit params ./GLOBALS??#GLOBALS必須大寫，編輯GLOBALS需要推出ggsci再進入，輸入：
?? ?CHECKPOINTTABLE hr.checkpoint?

?? ?查看CHECKPOINT TABLE
?? ?mysql> use hr
?? ?Reading table information for completion of table and column names
?? ?You can turn off this feature to get a quicker startup with -A

?? ?Database changed
?? ?mysql> show tables;
?? ?+--------------+
?? ?| Tables_in_hr |
?? ?+--------------+
?? ?| checkpoint?? |
?? ?+--------------+
?? ?1 row in set (0.00 sec)

?? ?mysql>

?? ? 5.4 創建replicat：

?? ?GGSCI (dg2) 10> add replicat rep2my,exttrail /opt/app/ggs/11.2/dirdat/my,checkpointtable hr.checkpoint
?? ?REPLICAT added.

?? ?GGSCI (ractdg3) 8> info all

?? ?Program???? Status????? Group?????? Lag at Chkpt? Time Since Chkpt

?? ?MANAGER???? RUNNING????????????????????????????????????????? ?
?? ?REPLICAT??? STOPPED???? REP2MY????? 00:00:00????? 00:00:02?? ?


?? ?GGSCI (ractdg3) 9> edit params rep2my

?? ?GGSCI (ractdg3) 10> view params rep2my

?? ?REPLICAT rep2my
?? ?sourcedefs /opt/app/ggs/11.2/dirdef/ext2my.def
?? ?--APPLYNOOPUPDATES
?? ?--HANDLECOLLISIONS
?? ?SOURCEDB hr,userid root,password 123456
?? ?discardfile /opt/app/ggs/11.2/dirrpt/rep2my_discard.log,megabytes 10
?? ?MAP hr.*, TARGET? hr.*;
?? ??? ?
?? ?GGSCI (ractdg3) 19> start REPLICAT REP2MY
?? ?GGSCI (ractdg3) 20> info all

?? ?Program???? Status????? Group?????? Lag at Chkpt? Time Since Chkpt

?? ?MANAGER???? RUNNING????????????????????????????????????????? ?
?? ?REPLICAT??? RUNNING???? REP2MY????? 00:00:00????? 00:00:05

?? ? 5.5 添加同步表并測試
?? ?[root@ractdg3 11.2]# mysql -u root -p -S '/tmp/mysql.sock'
?? ?Enter password:
?? ?Welcome to the MySQL monitor.? Commands end with ; or \g.
?? ?Your MySQL connection id is 5
?? ?Server version: 5.6.13-enterprise-commercial-advanced MySQL Enterprise Server - Advanced Edition (Commercial)

?? ?Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.

?? ?Oracle is a registered trademark of Oracle Corporation and/or its
?? ?affiliates. Other names may be trademarks of their respective
?? ?owners.

?? ?Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

?? ?mysql> use hr;
?? ?Reading table information for completion of table and column names
?? ?You can turn off this feature to get a quicker startup with -A
?? ?mysql> create table tst(id integer,constraint pk_tst_id primary key (id));
?? ?Query OK, 0 rows affected (0.02 sec)

?? ?mysql> show tables;
?? ?+--------------+
?? ?| Tables_in_hr |
?? ?+--------------+
?? ?| checkpoint?? |
?? ?| tst????????? |
?? ?+--------------+
?? ?2 rows in set (0.00 sec)

?? ?mysql> create table TST(ID INT,CONSTRAINT PK_TST_ID PRIMARY KEY(ID));
?? ?
?? ?mysql> DESC TST;
?? ?+-------+---------+------+-----+---------+-------+
?? ?| Field | Type??? | Null | Key | Default | Extra |
?? ?+-------+---------+------+-----+---------+-------+
?? ?| ID??? | int(11) | NO?? | PRI | 0?????? |?????? |
?? ?+-------+---------+------+-----+---------+-------+
?? ?1 row in set (0.00 sec)

?? ?mysql> select * from TST;
?? ?+----+
?? ?| ID |
?? ?+----+
?? ?|? 3 |
?? ?+----+
?? ?1 row in set (0.00 sec)

?? ?看到數據已同步過來了，MYSQL 中，表名有大小寫區分，開始報表名TST找不到，是在建立表中使用的是tablename:tst
