早期的导出命令：

[root@powerlong4 ~]# su - oracle [oracle@powerlong4 ~]$ export ORACLE_SID=pt1; [oracle@powerlong4 ~]$ expdp \'sys/systestpd as sysdba\' DIRECTORY=dir_dump_t3 FULL=YES DUMPFILE=expdpfull_pd_20150529_02.dmp ......

1，開始导入

先在实例2上建立管道文件夹：

[oracle@pttest4 ~]$ export ORACLE_SID=pt2; [oracle@pttest4 ~]$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.1.0 Production on Wed Jun 3 21:22:43 2015Copyright (c) 1982, 2009, Oracle. All rights reserved.Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing optionsSQL> CREATE OR REPLACE DIRECTORY dir_dump_t3 AS '/home/oracle/expdpimpdp/';Directory created.SQL>

開始导入全库备份集：

impdp \'sys/syspddev@pt2 as sysdba\' directory=dir_dump_t3 dumpfile=expdpfull_pd_20150529_02.dmp nologfile=y TABLE_EXISTS_ACTION=REPLACE ......

2，导入报错：

ORA-02374: conversion error loading table "puser"."RES_APPROVE_CONTENT" ORA-12899: value too large for column CREATED_POSITION_CD (actual: 24, maximum: 20)

3，怀疑导入目标错误，验证：

[oracle@pttest4 admin]$ export ORACLE_SID=pt2; [oracle@pttest4 admin]$ [oracle@pttest4 admin]$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.1.0 Production on Fri May 29 21:06:27 2015Copyright (c) 1982, 2009, Oracle. All rights reserved.Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing optionsSQL> SQL> SQL> select name from v$database;NAME ------------------ pt2SQL>

4。检查两者的编码

到出库实例库1：

SQL> SELECT * FROM V$NLS_PARAMETERS WHERE PARAMETER IN ('NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET'); PARAMETER VALUE ---------------------------------------------------------------- ---------------------------------------------------------------- NLS_CHARACTERSET ZHS16GBK NLS_NCHAR_CHARACTERSET AL16UTF16SQL>

到导入的库实例2库

看到导出导入库实例1实例2的字符集不同，所以问题就在这里了

5，解决：

[oracle@pttest4 admin]$ export ORACLE_SID=pt2; [oracle@pttest4 admin]$ [oracle@pttest4 admin]$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.1.0 Production on Fri May 29 21:06:27 2015Copyright (c) 1982, 2009, Oracle. All rights reserved.Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing optionsSQL> SQL>connect username/password as SYSDBA; SQL>SHUTDOWN IMMEDIATE; SQL>STARTUP MOUNT; SQL>ALTER SYSTEM ENABLE RESTRICTED SESSION; SQL>ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0; SQL>ALTER SYSTEM SET AQ_TM_PROCESSES=0; SQL>ALTER DATABASE OPEN;SQL> ALTER DATABASE CHARACTER SET ZHS16GBK ; ALTER DATABASE CHARACTER SET ZHS16GBK; *ERROR at line 1: ORA-12712: new character set must be a superset of old character set 报字符集不兼容，此时下INTERNAL_USE指令不正确字符集超集进行检查：SQL>ALTER DATABASE CHARACTER SET INTERNAL_USE ZHS16GBK; SQL>SHUTDOWN IMMEDIATE; SQL>STARTUP;

6，再去检查两个实例的编码

[oracle@pttest4 expdpimpdp]$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.1.0 Production on Fri May 29 21:32:12 2015Copyright (c) 1982, 2009, Oracle. All rights reserved.Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing optionsSQL> select name from v$database;NAME --------- pt2SQL> SQL> SELECT * FROM V$NLS_PARAMETERS WHERE PARAMETER IN ('NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET'); Warning: connection was lost and re-established PARAMETER VALUE ---------------------------------------------------------------- ---------------------------------------------------------------- NLS_CHARACTERSET ZHS16GBK NLS_NCHAR_CHARACTERSET AL16UTF16SQL>

导出实例上：

[oracle@pttest4 expdpimpdp]$ export ORACLE_SID=pt1; [oracle@pttest4 expdpimpdp]$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.1.0 Production on Fri May 29 21:32:50 2015Copyright (c) 1982, 2009, Oracle. All rights reserved.Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing optionsSQL> select name from v$database;NAME --------- pt1SQL> SELECT * FROM V$NLS_PARAMETERS WHERE PARAMETER IN ('NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET'); PARAMETER VALUE ---------------------------------------------------------------- ---------------------------------------------------------------- NLS_CHARACTERSET ZHS16GBK NLS_NCHAR_CHARACTERSET AL16UTF16SQL>

此时，两个实例上字符集一模一样了，保持一致。

7。又一次导入impdp

[oracle@pttest4 admin]$ export ORACLE_SID=pt2; [oracle@pttest4 admin]$ impdp \'sys/sysdevpd@pt2 as sysdba\' directory=dir_dump_t3 dumpfile=expdpfull_pd_20150529_02.dmp nologfile=y TABLE_EXISTS_ACTION=REPLACE

OK，一切正常，能够导入到实例2上面了。
