oracle9i在进行全库备份时出现EXP-00008: ORACLE error 1187 encountered的解决办法

oracle9i在进行数据库全库备份时出现如下错误：

Connected to: Oracle9i Enterprise Edition Release 9.2.0.8.0 - Production

EXP-00008: ORACLE error 1187 encountered
ORA-01187: cannot read from file 201 because it failed verification tests
ORA-01110: data file 201: '/opt/ora9/product/oradata/NTDB/temp1.dbf'
EXP-00000: Export terminated unsuccessfully
从上面的错误信息可以看出是temp临时表空间的数据文件有问题，解决办法：
1、删除临时表空间： alter database tempfile '/opt/ora9/product/oradata/NTDB/temp1.dbf' drop;
2、重建数据文件：
alter tablespace temp add tempfile '/opt/ora9/product/oradata/NTDB/temp01.dbf' size 512M REUSE AUTOEXTEND ON NEXT  1M MAXSIZE UNLIMITED;
通过上述两个步骤就可以解决在进行数据库备份时出现的ORACLE error 1187 encountered错误。
