强大的ORACLE早已为我们考虑到这一点并提供了一个简单实用的工具：oerr，在linux或unix环境下，通过这个工具，可以快速找到相应错误代码的概述及解决方案。
下面，就演示一下oerr的使用方法：
语法
操作系统命令行（管理员账号下）：oerr ora xxxx
sqlplus命令行：!oerr ora xxxx
这里的ora还可以是rman、TNS、EXP、IMP、NID等
示例1：
[oracle@localhost ~]$ oerr ora 3136
03136,00000,"inbound connection timed out"
// *Cause: Inbound connection was timed out by the server because
// user authentication was not completed within the given time
// specified by sqlNET.INBOUND_CONNECT_TIMEOUT or its default value
// *Action: 1) Check sql*NET and RDBMS log for trace of suspicIoUs connections.
// 2) Configure sql*NET with a proper inbound connect timeout value
// if necessary.
[oracle@localhost ~]$
示例2：
[oracle@localhost ~]$
[oracle@localhost ~]$ sqlplus / as sysdba

sql> !oerr ora 3136
03136,"inbound connection timed out"
// *Cause: Inbound connection was timed out by the server because
// user authentication was not completed within the given time
// specified by sqlNET.INBOUND_CONNECT_TIMEOUT or its default value
// *Action: 1) Check sql*NET and RDBMS log for trace of suspicIoUs connections.
// 2) Configure sql*NET with a proper inbound connect timeout value
// if necessary.
示例3：
[oracle@localhost ~]$
[oracle@localhost ~]$ oerr rman 1008
1008,1,"the bad identifier was: %s"
// *Cause: This is an informational message indicating the identifier token
// that caused a Syntax error.
// *Action: No action is required.
[oracle@localhost ~]$
[oracle@localhost ~]$
示例4：
[oracle@localhost ~]$ oerr TNS 12500
12500,"TNS:listener Failed to start a dedicated server process"
// *Cause: The process of starting up a dedicated server process Failed.
// The executable could not be found or the environment may be set up
// incorrectly.
// *Action: Turn on tracing at the ADMIN level and reexecute the operation.
// Verify that the ORACLE Server executable is present and has execute
// permissions enabled. Ensure that the ORACLE environment is specified
// correctly in LISTENER.ORA. The Oracle Protocol Adapter that is being
// called may not be installed on the local hard drive. Please check that
// the correct Protocol Adapter are successfully linked.
// If error persists,contact Oracle Customer Support.
示例5： [oracle@localhost ~]$ [oracle@localhost ~]$ oerr EXP 00089 00089,"invalid FILE_FORMAT specification" // *Cause: The FILE_FORMAT specification did not contain an // instance of "%s". This wildcard string must be present. // *Action: Correct the error and reenter the EXPORT command. [oracle@localhost ~]$
