Goldengate双向复制配置

云技术五哥 • • 关系数据库 • 阅读 111

一、Goldengate双向复制配置1.1.在进行如下配置之前，先在源数据库source system（原来的目标数据库）端添加辅助的redolog配置：SQL>alter database add supplemental log data;SQL>alter system switch logfile;SQL>alter database force logging;1.2.在原Source和原Target分别用scott用户创建一张emp_ogg表SQL> create table emp_ogg as select * from emp
where 1=0; //原source库建立表但不插入数据Table created.单项复制时Source端是EINI_1进程，Target端是RINI_1进程,双向复制时反之，以便完成两表的初始化同步，配置如下：原SourceGGSCI (gc2) 36> ADD REPLICAT RINI_1, SPECIALRUNREPLICAT added.GGSCI (gc2) 43> EDIT PARAMS RINI_1— GoldenGate Initial Load Delivery—REPLICAT RINI_1SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)ASSUMETARGETDEFSUSERID ogg, PASSWORD oggDISCARDFILE ./dirrpt/RINIaa.dsc, PURGEMAP scott.*, TARGET scott.*;原TargetGGSCI

———– ——————————recyclebin
string off必须是off这里执行第二个脚本@ddl_setup时会报一个recyclebin的错误，而且只能在Pfile中修改recyclebin=off后用pfile起库，执行两个清除脚本，再重新运行一下脚本SQL>@marker_setupSQL>@ddl_setupSQL>@role_setupSQL>grant GGS_GGSUSER_ROLE to ogg;SQL>@ddl_enable如果某项脚本执行错误，需要重新执行时，先要执行清除的脚本：ddl_remove.sql和marker_remove.sql
