IMP-00098: INTERNAL ERROR: impgst2
报错说明：
OCI-21500: internal error code, arguments: [string], [string], [string], [string], [string], [string], [string], [string]
Cause: This is the generic error number for the OCI environment (client-side) internal errors. This indicates that the OCI environment has encountered an exceptional condition.Action: Report as a bug - the first argument is the internal error number.
OCI-22275: invalid LOB locator specified
Cause: There are several causes: (1) the LOB locator was never initialized; (2) the locator is for a BFILE and the routine expects a BLOB/CLOB/NCLOB locator; (3) the locator is for a BLOB/CLOB/NCLOB and the routine expects a BFILE locator; (4) trying to update the LOB in a trigger body -- LOBs in trigger bodies are read only.
Action: For (1), initialize the LOB locator by selecting into the locator variable or by setting the LOB locator to empty. For (2) and (3), pass the correct type of locator into the routine. For (4), remove the trigger body code that updates the LOB value.
解决思路：
1.数据导出的时候按照 用户进行导出，并且采用了直接路径 direct=y
exp xyy/xyy@sspt OWNER=GSYY DIRECT=Y RECORDLENGTH=65535 BUFFER=104857600 FILE=/opt/oradata/exp/GSYY.dmp LOG=/opt/oradata/exp/log/GSYY.log
查询导入日志，发现并未报错：
. . exporting table FP_HGWSPZ 0 rows exported
. . exporting table GS_DJ_NSRXX 0 rows exported
. . exporting table HD_HDXX 3219563 rows exported
2.查询表 HD_HDXX ，发现含有LOB字段数据
SQL> desc GSYY.HD_HDXX;
Name Null? Type
----------------------------------------- -------- ----------------------------
SBNY NOT NULL CHAR(6)
NSRSBH NOT NULL VARCHAR2(20)
SWJG_DM NOT NULL VARCHAR2(11)
LRR_DM NOT NULL VARCHAR2(11)
LRRQ NOT NULL DATE
XGR_DM NOT NULL VARCHAR2(11)
XGRQ NOT NULL DATE
HDXX CLOB
FPLGXX VARCHAR2(4000)
JXFP_MX CLOB
XXFP_HZ VARCHAR2(4000)
HGWSFP_MX CLOB
JDCJXFP_MX CLOB
3.直接路径导出 direct=y 不支持导出含有LOB、BFILE等大对象的表，进行单独 导出 GSYY.HD_HDXX，再进行导入，发现正常无报错。
