15)repadmin－－在eygle上，添加主体复制节点，这里选择同步synchronous模式，实时的同步：

SQL> execute dbms_repcat.add_master_database(gname=>'rep_cjh',master=>'BITI.TEST.COM.CN',use_existing_objects=>true, copy_rows=>false, propagation_mode => 'synchronous');

CJH                            CJH$RP                         VALID      REP_CJH
CJH                            CJH$RP                         VALID      REP_CJH

17)repadmin－－在eygle上，启动复制

SQL> select * from global_name;

GLOBAL_NAME
----------------------------------------------------------------------------------------------------
EYGLE.TEST.COM.CN

SQL> execute dbms_repcat.resume_master_activity('rep_cjh',true);

PL/SQL procedure successfully completed.

18)cjh－－在eygle上，删除数据测试

SQL> select count(*) from cjh.cjh;

COUNT(*)
----------
100

SQL> delete from cjh.cjh where rownum<20;

19 rows deleted.

SQL> commit;

Commit complete.

19)cjh－－在biti上，数据变化

SQL> select count(*) from cjh.cjh;

COUNT(*)
----------
81

20)同时，在biti这里改变数据，eygle这里也会同步过来，测试通过。
