使用ogg数据初始化时，如果我们手工去启动初始化的复制进程，
如下：
GGSCI (server2 as ogg@orcl) 63> start rini_1
会报以下错误：
2019-05-10T16:46:28.867+0800 INFO OGG-06604 Oracle GoldenGate Delivery for Oracle, rini_1.prm: Database ORCL CPU info: CPU Count 4, CPU Core Count 4, CPU Socket Count 2.
2019-05-10T16:46:28.867+0800 WARNING OGG-05673 Oracle GoldenGate Delivery for Oracle, rini_1.prm: CSN-based duplicate suppression is disabled because there is no checkpoint table for this Replicat.
2019-05-10T16:46:28.867+0800 ERROR OGG-02161 Oracle GoldenGate Delivery for Oracle, rini_1.prm: Failed to retrieve the trail file begin checkpoint position.
2019-05-10T16:46:28.867+0800 ERROR OGG-01668 Oracle GoldenGate Delivery for Oracle, rini_1.prm: PROCESS ABENDING.
正确的姿势是，启动源端的初始化抽取进程，会自动启动目标端的初始复制进程。
比如：
源端 ：
GGSCI (dbserver) 12> start eini_1
Sending START request to MANAGER ...
EXTRACT EINI_1 starting
目标端 ：
GGSCI (server2 as ogg@orcl) 58> info *,task
REPLICAT RINI_1 Initialized 2019-05-10 16:17 Status RUNNING
Checkpoint Lag 00:00:00 (updated 00:20:13 ago)
Process ID 14340
Log Read Checkpoint Not Available
Task SPECIALRUN
并且初始复制完成后，初始复制进程会自动停止，不需要人工干预。
