搭建Oracle 到Oracle 的Golden Gate 单向复制测试环境

一、安装ＧＧ

在

（１）添加环境变量，在/home/oracle/.bash_profile文件里添加如下内容：

export PATH=/u01/ggate:$PATH

exportLD_LIBRARY_PATH=/u01/ggate:$LD_LIBRARY_PATH

export ggtest=/u01/ggate

这里的

source/home/oracle/.bash_profile

（２）使用ggsci工具，创建必要的目录

gg1:/u01/ggate> ggsci

二、分别配置ｓｏｕｒｃｅ和ｔａｒｇｅｔ

（１）GoldenGate通过抓取源端数据库重做日志进行分析，将获取的数据应用到目标端，，实现数据同步。因此，源数据库需要必须处于归档模式，并启用附加日志和强制日志。

归档模式、附加日志、强制日志

--查看

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

LOG_MODE SUPPLEME FOR

------------ -------- ---

ARCHIVELOG NO NO

--修改

（

SQL>shutdown immediate

SQL>startup mount

SQL>alter database archivelog;

SQL>alter database open;

（

SQL>alterdatabase force logging;

（

SQL>alterdatabase add supplemental log data;

（２）禁用Recycle Bin

如果启用

If the recyclebin is enabled, the Oracle GoldenGate DDL trigger session receives implicitrecycle bin DDL operations that cause the trigger to fail.

Oracle 11g：

SQL> alter system set recyclebin=offscope=spfile;

System altered.

如果数据库是

（３）创建存放

SQL> create user ggtest identified by oracle default tablespace users temporary tablespace temp;

User created.

SQL> grant connect,resource to ggtest;

Grant succeeded.

SQL> grant execute on utl_file to ggtest;

Grant succeeded.

gg1:/u01/ggate> echo $ggate

/u01/ggate

gg1:/home/oracle> cd $ggate

gg1:/u01/ggate> sqlplus / as sysdba;
