系统命令OERR查看oracle错误信息

参考文档：http://blog.itpub.net/23718752/viewspace-2082156/

oracle出现ORA-的错误信息时，可以使用系统命令oerr直接查看错误相关信息。

oerr命令得到的错误信息是$ORACLE_HOME/bin/路径下的bash文件oerr调用perl文件oerr.pl实现的。

本次测试系统版本是redhat6.6。

文件信息：

[oracle@ bin 10:47:09]$ pwd
/u01/app/oracle/product/12.1.0.2/bin
[oracle@ bin 10:47:10]$
[oracle@ bin 10:47:10]$ ll *err*
-rwxr-xr-x. 1 oracle dba  703 Jan  1  2000 oerr
-rw-r--r--. 1 oracle dba 4921 Jan  1  2000 oerr.pl

 oerr命令后面接两个参数，格式为‘oerr  错误类型   错误编号’，除了可以查看ora类型的错误，还可以看tns等类型的错误：

[oracle@ bin 10:54:34]$ oerr ora 1
00001, 00000, "unique constraint (%s.%s) violated"
// *Cause: An UPDATE or INSERT statement attempted to insert a duplicate key.
//         For Trusted Oracle configured in DBMS MAC mode, you may see
//         this message if a duplicate entry exists at a different level.
// *Action: Either remove the unique restriction or do not i nsert the key.

[oracle@ ~ 11:19:01]$ oerr  tns  505
00505, 00000, "Operation timed out"
// *Cause: The requested operation could not be completed within the timeout
// period.
// *Action: For further details, turn on tracing and reexecute the operation.

 从文件oerr.pl中可以看到有使用一个配置文件$ORACLE_HOME/lib/facility.lis，其中就有相关参数信息。文件中有说明参数格式为facility:component:rename:description。

[oracle@ ~ 11:21:35]$ cat $ORACLE_HOME/lib/facility.lis
