请教高手oracle11g expdp exclude参数问题

1.未带exclude过滤表的导出日志：
Starting "****"."SYS_EXPORT_SCHEMA_01": ****/******** DIRECTORY=DUMP_MDS_DIR DUMPFILE=****_20110921.dmp LOGFILE=exp_****_20110921.log SCHEMAS=****

. . exported "***"."TBL_REQUEST_DETAIL":"SYS_P675" 278.2 MB 295289 rows

2.添加了exclude参数的导出日志
Starting "****"."SYS_EXPORT_SCHEMA_01": ****/******** DIRECTORY=DUMP_MDS_DIR DUMPFILE=****_20110921.dmp LOGFILE=exp_****_20110921.log parfile=/opt/oracle/test.par

. . exported "***"."TBL_REQUEST_MESSAGE":"SYS_P674" 432.6 MB 653096 rows
. . exported "***"."TBL_REQUEST_DETAIL":"SYS_P675" 278.2 MB 295289 rows

. . exported "***"."TBL_REQUEST_DETAIL":"SYS_P675" 278.2 MB 295289 rows
这个是需要过滤的表

过滤参数放在parfile=/opt/oracle/test.par里面了，参考如下：
EXCLUDE=TABLE:"IN('${TABLE1}','${TABLE2}','${TABLE3}','${TABLE4}','${TABLE5}','${TABLE6}','${TABLE7}')"

但是实际1 的日志与2 的日志一模一样，导出的dump文件大小也一模一样，是日志就是这么显示的，还是导出结果有问题？
