Goldengate can't extract data from compressed table

OGG目前不支持对10g以后压缩表(compressed table)的extract，若挖掘到压缩表相关的DML纪录则extract会abend:

SQL> alter table sales compress 2;
Table altered.

SQL>  update sales set  AMOUNT_SOLD= AMOUNT_SOLD +1 where rownum<200;
199 rows updated.

SQL> commit;
Commit complete.

extract report:
