這裡有個偏方，修復資料塊用的，我轉貼一下

Oracle10g提供了bbed工具，但是同樣需要我們手工編譯一下:

[oracle@danaly lib]$ make -f ins_rdbms.mk $ORACLE_HOME/bin/bbed

make: Nothing to be done for `/opt/oracle/product/10.2.0/bin/bbed'.

[oracle@danaly lib]$ make -f ins_rdbms.mk $ORACLE_HOME/rdbms/lib/bbed

Linking BBED utility (bbed)

rm -f /opt/oracle/product/10.2.0/rdbms/lib/bbed

gcc -o /opt/oracle/product/10.2.0/rdbms/lib/bbed ...

-L/opt/oracle/product/10.2.0/lib

[oracle@danaly lib]$ bbed

BBED的預設口令為blockedit,請謹慎使用,內部工具。Oracle不做技術支援

記住了，偏方有時好用，但是最好還是做好備份
