ORACLE GoldenGate 配置

OGG配置的整个过程

1.1 复制数据库
使用RMAN 复制：

    [oracle@dg1 ~]$ rman target sys/sa@db1 auxiliary sys/sa@db2 nocatalog
    RMAN> duplicate target database to DB2 nofilenamecheck;




1.2 安装配置oracle GoldenGate

1.2.1 修改环境变量，LD_LIBRARY_PATH=/opt/app/ggs/11.2

vi ~/.bash_profile

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/opt/app/ggs/11.2; export LD_LIBRARY_PATH

1.2.2 安装goldengate
    $ Su – oracle $ mkdir -p /ggs/11.2
    $ chown -R oracle:oinstall /ggs/11.2 $ chmod -R 775 /ggs/11.2
    $ cd /ggs/11.2
    $ unzip ogg112101_fbo_ggs_Linux_x86_ora10g_32bit.zip $ tar xvf fbo_ggs_Linux_x86_ora10g_32bit.tar 
    cd /opt/app/ggs/11.2
    [oracle@dg2 11.2]$./ggsci

    GGSCI (dg1) 2>


    1.2.3 建立用户,并赋权限：
    主库：
    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.

    备库：
    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;

    SQL> grant insert any table,update any table,delete any table to ggs;

    Grant succeeded.

    1.3 源、目标库打开辅助日志

    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


    1.4 源、目标库支持sequence

    在源库、目标库上执行：
    GGSCI (dg2) 2> edit params ./globals
    在统计模式下输入并保存：ggschema ggs

    在SQLPLUS 下去运行：
    sql> @sequence.sql 根据提示输入：gg


    1.5 支持ddl复制

    1.2.5.1 主库配置
    cd /ggs/11.2
    sqlplus / as sysdba
    sql> alter system set recyclebin=off deferred scope=both;  #必须，针对ddl复制
    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需要安装dbms_share_pool包：
    sql> @?/rdbms/admin/dbmspool.sql sql> @ddl_pin ggs;

    1.6 目标库配置
    sql> alter system set recyclebin=off deferred scope=both;  #必须
    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需要安装dbms_share_pool包：
    sql> @?/rdbms/admin/dbmspool.sql sql> @ddl_pin ggs;

    1.7 配置MANAGER
    主库、目标库配置：
    [oracle@dg1 11.2]$ ./ggsci

    创建checkpoint表
    ggsci>dblogin userid ggs,password ggs
    ggsci>add checkpointtable ggs.checkpoint
    ggsci> edit params ./GLOBALS  #GLOBALS必须大写，编辑GLOBALS需要推出ggsci再进入，输入：
    CHECKPOINTTABLE ggs.checkpoint
