标题: 利用ORACLE自身功能查错误
有些时候，手头没有官方文档，也不能上网时，遇到一个错误，还挺麻烦的，

还好，安装了ORACLE数据库的机器，自带查错的脚本，就是oerr 。

文件位置在:

[oracle@host01 ~]$ which oerr
/u01/app/oracle/product/19.3.0/db_1/bin/oerr
[oracle@host01 ~]$ ls -ltr /u01/app/oracle/product/19.3.0/db_1/bin/oerr
-rwxr-xr-x 1 oracle oinstall 703 Jan  1  2000 /u01/app/oracle/product/19.3.0/db_1/bin/oerr
[oracle@host01 ~]$
[oracle@host01 ~]$ file /u01/app/oracle/product/19.3.0/db_1/bin/oerr
/u01/app/oracle/product/19.3.0/db_1/bin/oerr: POSIX shell script, ASCII text executable
[oracle@host01 ~]$
[oracle@host01 ~]$
[oracle@host01 ~]$ cat /u01/app/oracle/product/19.3.0/db_1/bin/oerr
#!/bin/sh

# Usage: oerr facility error
#
# This shell script is a driver to invoke oerr.pl using the perl shipped in
# Oracle home.
#

#
# Turn on script tracing if, requested
[ "$ORACLE_TRACE" = "T" ] && set -x

#
# If ORACLE_HOME is not set, we will not be able to locate
# the facilities file or message text file.
if [ ! "$ORACLE_HOME" ]
then
      echo "ORACLE_HOME not set.  Please set ORACLE_HOME and try again." 1>&2
      exit 1
fi

PERL_DIR=$ORACLE_HOME/perl
PERL_BIN=$PERL_DIR/bin
export PERL_BIN

$PERL_BIN/perl $ORACLE_HOME/bin/oerr.pl "$@"

exit 0

可以看出，是使用PERL写的一段代码，有兴趣的可以去看看。

具体使用，比如我们遇到一个错误，比如引用分区创建报错：

ORA-14652: 不支持引用分区外键

这个时候，就可以直接使用oerr ora 14652 ,马上就可以看到错误了。

[size=18.6667px][oracle@host01 ~]$ oerr ora 14652
14652, 00000, "reference partitioning foreign key is not supported"
// *Cause:  The specified partitioning foreign key was not supported
//       for reference-partitioned tables. All columns of the
//       partitioning foreign key must be constrained NOT NULL with
//       enabled, validated, and not deferrable constraints. Furthermore,
//       a virtual column cannot be part of the partitioning foreign key.
//* Action: Correct the statement to specify a supported
//       partitioning foreign key.

是不是很方便。
