现象：
GG做init data load时，报错OGG-01192，OGG-01668
2013-11-12 10:43:44 ERROR OGG-01192 Oracle GoldenGate Capture for Oracle, ext2.prm: Trying to use RMTTASK on data types which may be written as LOB chunks (Table: 'PORTAL.UNID_PAPER').
2013-11-12 10:43:44 ERROR OGG-01668 Oracle GoldenGate Capture for Oracle, ext2.prm: PROCESS ABENDING.
extract ext2的配置为：

TABLE PORTAL.*;
GGSCI (RAC01) 2>
分析：
PORTAL.UNID_PAPER表包含有BLOB字段，不能直接采用init data load的方式。
SQL> desc PORTAL.UNID_PAPER
Name Null? Type
----------------------------------------- -------- ----------------------------
ID NOT NULL NUMBER(38)
SMALL_IMAGE BLOB
BIG_IMAGE BLOB
DESCRIPTION VARCHAR2(100)
解决方法：
采用File to Replicat - Initial Load Techniques。
The rmtask does not support extraction of LOB or LONG data. As an alternative, see “Loading data from file to Replicat” , use rmtfile instead.
The initial load techniques are available at Doc ID 1441172.1
