导出的步骤很简单,主要注意下面红色的问题:
1)xmlschema-base columes只能用老exp导出
2)字符集问题
参考
1)
SQL> create or replace directory expdir as '/dump';
SQL> GRANT read,write ON DIRECTORY expdir TO public;
# chown -R oracle:oinstall /dump
# chmod -R 755 /dump
expdp system/open1sys full=y DIRECTORY=expdir DUMPFILE=df1.dmp LOGFILE=lf1.log
if you have xmlschema-base columes
Cause: Object has XMLSchema-based columns, which are
unsupported by Data Pump.
Action: Use the original exp and imp utilities to move this
object.
exp system/open1sys full=y file=/dump/dfdirect.dmp direct=y
if EXP-00091: Exporting questionable statistics happened.
Export terminated successfully with warnings.
