  • 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:
