delete replicat rep2!
通过惊叹号来进行强制删除

Here, The “!” tells GoldenGate to ignore the checkpoint tableIf we wish to create Replicat  without checkpoint then use below command to create ADD REPLICAT <group>, EXTTRAIL <trail>, NODBCHECKPOINTIf we want to create Replicat  WITH checkpoint then use below command to create ADD CHECKPOINTTABLE ggs_admin.ggchkpt          ( create if not exists) ADD REPLICAT <group>, EXTTRAIL <trail>,  CHECKPOINTTABLE ggs_admin.ggchkpt
