oerr linux/unix下oracle查看错误概述

gggggds

　　oracle的错误成千上万，我们能记住的可能只有自己工作中会经常碰到的一些错误。oracle提供了一个简单实用的命令oerr来查询错误的简单信息
　　--注意：linux/unix平台下装完oracle就可以直接实用该命令，windows需要实用第三方工具）
　　oerr命令使用方式如下
　　[root@localhost ~]# su - oracle
　　[oracle@localhost ~]$ oerr ora 01652
　　01652, 00000, "unable to extend temp segment by %s in tablespace %s"
　　// *Cause:  Failed to allocate an extent of the required number of blocks for
　　//          a temporary segment in the tablespace indicated.
　　// *Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more
　　//          files to the tablespace indicated.
　　其他的oracle报错查看方式同上
　　如使用exp时报错
　　[oracle@localhost ~]$ oerr exp 00091
　　00091, 00000, "Exporting questionable statistics."
　　// *Cause:  Export was able export statistics, but the statistics may not be
　　//          usuable. The statistics are questionable because one or more of
　　//          the following happened during export: a row error occurred, client
　　//          character set or NCHARSET does not match with the server, a query
　　//          clause was specified on export, only certain partitions or
　　//          subpartitions were exported, or a fatal error occurred while
　　//          processing a table.
　　// *Action: To export non-questionable statistics, change the client character
　　//          set or NCHARSET to match the server, export with no query clause,
　　//          export complete tables. If desired, import parameters can be
　　//          supplied so that only non-questionable statistics will be imported,
　　//          and all questionable statistics will be recalculated.
