Goldengate一个令人郁闷的小细节

晚上有兴趣测试了下Goldengate的initial load功能,通过initial load+change sync可以很容易做到数据迁移data migration;不过发现一个令人很郁闷的细节,就是replicat的params中定义map参数时TARGET到前面一个逗号间要留一个空格space:

MAP table spec, TARGET table spec     
/*TARGET到前面一个逗号间要留一个空格space*/
[, DEF ]
[, TARGETDEF ]
[, COLMAP ()]
[, EVENTACTIONS ()]
[, EXCEPTIONSONLY]
[, EXITPARAM “”]
[, FILTER ()]
[, HANDLECOLLISIONS | NOHANDLECOLLISIONS]
[, INSERTALLRECORDS]
[, INSERTAPPEND | NOINSERTAPPEND]
[, KEYCOLS ()]
[, REPERROR ( , )]
[, SQLEXEC ()]
[, TRIMSPACES | NOTRIMSPACES]
[, WHERE ()]
;

如果map参数中target和前面的逗号间没有空格会出现invaild option for map错误:
