异构GoldenGate 12c 单向复制配置
1.分别在windows2008、linux平台部署oracle 11.2.0.4
2.分别在windows2008、linux平台部署gg。
2.1 windows平台：
gg的安装目录位
C:\ora11g\product\ogg_src 需设置环境变量 ORACLE_HOME and ORACLE_SID 2.2 linux平台：
gg的安装目录位
[oracle@Oracle02 ~]$ ls -l /u01/app/oracle/product/
drwxrwxr-x. 3 oracle oinstall 4096 12月 13 10:21 11.2.0
drwxr-xr-x. 26 oracle oinstall 4096 12月 13 11:24 ogg_src
[oracle@Oracle02 ~]$ 需设置环境变量 export LD_LIBRARY_PATH=$ORACLE_HOME/lib
需要安装readline-devel-6.0-4.el6.x86_64.rpm（在linux平台 ） 3.启动ogg的mgr管理进程，source和target端做相同的操作
3.1 启动wind的ogg的mgr
C:\ora11g\product\ogg_src>ggsci.exe
GGSCI (WIN-GM5PVS1CILH) 1> start mgr
Manager started.
GGSCI (WIN-GM5PVS1CILH) 2> info mgr
Manager is running (IP port WIN-GM5PVS1CILH.7809, Process ID 232). 3.2 启动linux的ogg的mgr
[oracle@Oracle02 product]$ cd ogg_src
[oracle@Oracle02 ogg_src]$ ./ggsci
GGSCI (Oracle02) 1> start mgr
MGR is already running.
GGSCI (Oracle02) 2> info mgr
Manager is running (IP port Oracle02.7809, Process ID 21213).
GGSCI (Oracle02) 3> 4准备工作，在source和target端都配置
4.1配置tnsnames.ora文件
orcl_w =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.100)(PORT = 1521))
)
(CONNECT_DATA =
(SID =orcl )
)
)
orcl_L =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.21)(PORT = 1521))
)
(CONNECT_DATA =
(SID =orcl )
)
) 4.2 调整数据库
#确定数据库运行在归档模式，，
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 2
Next log sequence to archive 4
Current log sequence 4 #开启数据库附加日志
SQL> select supplemental_log_data_min from v$database;
SUPPLEME
--------
NO
SQL> alter database add supplemental log data; SQL> select supplemental_log_data_min from v$database; SUPPLEME
--------
YES #打开force logging
SQL> alter database force logging;
SQL> 4.3 创建单独用于复制的数据库账号
SQL> create tablespace tbs_ogg;
SQL> create user ggs identified by ggs default tablespace tbs_ogg temporary tablespace temp account unlock;
SQL> grant connect,resource to ggs;
SQL> grant select any table to ggs;
SQL> grant select any dictionary to ggs; SQL> create tablespace tbs_ogg;
SQL> create user ggt identified by ggt default tablespace tbs_ogg temporary tablespace temp account unlock;
SQL> grant connect,resource to ggt;
SQL> grant select any table to ggt;
SQL> grant select any dictionary to ggt;
SQL> 5.准备测试用户和表
SQL> alter user scott identified by scott account unlock;
SQL> grant connect,resource,select_catalog_role to scott;
SQL>
SQL> conn scott/scott
SQL> create table t1 as select * from dba_objects;
SQL> alter table t1 add constraint pk_t1 primary key(object_id); SQL> select count(*) from t1; //source端
COUNT(*)
----------
86045
SQL> SQL> select count(*) from t1; //target端，只复制表定义，不填充数据 COUNT(*)
----------
0
SQL> 6.初始化加载数据
注：在异构数据库平台，这个功能显得非常的有用！而在oracle-oracle的数据复制条件下，oracle推荐使用expdp/impdp工具
6.1 source端添加extract进程
GGSCI (WIN-GM5PVS1CILH) 2> info mgr
Manager is running (IP port WIN-GM5PVS1CILH.7809, Process ID 232). GGSCI (WIN-GM5PVS1CILH) 3> add extract einig1,sourceistable //sourceistable代表直接从表中读取数据
EXTRACT added. GGSCI (WIN-GM5PVS1CILH) 4> edit params einig1 //einig1代表extract initial load group 1缩写 GGSCI (WIN-GM5PVS1CILH) 5> view params einig1 //查看设置后的参数

GGSCI (WIN-GM5PVS1CILH) 4> dblogin userid ggs, password ggs
Successfully logged into database. GGSCI (WIN-GM5PVS1CILH as ggs@orcl) 5> add trandata scott.* 7.3 添加extract进程，添加trail文件，文件名前缀不能超过2个字符
GGSCI (WIN-GM5PVS1CILH) 1> add extract eora_t1,tranlog,begin now
EXTRACT added. GGSCI (WIN-GM5PVS1CILH) 2> add exttrail dirdat/sp,extract eora_t1,megabytes 100
