Configure replicat(复制) process in target system-----------------------------------------
在目标端配置怎么接收,怎么处理传过来的信息
Create GLOBALS parameter in target system
Edit GLOBALS(upper case) parameter file to indicate checkpoint table
GGSCI (oraclelinux54.cuug.net) 5> EDIT PARAMS ./GLOBALS
CHECKPOINTTABLE ogg.ggschkpt 用到ogg下的checkpoint表
Verify:
