2022-12-01 15:13:28  ERROR   OGG-01668  PROCESS ABENDING.
2、异常原因
根据提示可知，enable_goldengate_replication参数未设置成true.

System altered.

4、验证
GGSCI (leo-19c-ogg as ogg@simdb) 8> start repa

Sending START request to MANAGER ...
REPLICAT REPA starting


GGSCI (leo-19c-ogg as ogg@simdb) 9> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                           
REPLICAT    RUNNING     REPA        00:00:00      00:00:00    

结论：修改参数后，目标端复制进程成功开启.
