ORA-00600 [ktrexc_1] 错误

昨天数据库在做MERGE的时候出现了一个600的错误，从网上找了很长时间都没有找到原因，ITPUB的一个网友给出了解决方法，原来是ORACLE的一个BUG。

错误提示如下：

ORA-00600: internal error code, arguments: [ktrexc_1], [], [], [], [], [], [], []

解决方法：

Set the hidden parameter "_row_cr" to false as a workaround for the bug as follow :

SQL> alter system set "_row_cr"=false scope=both ;

The parameter can be enabled/disabled  dynamically.

-This is a boolean parameter that defaults to FALSE. When set to TRUE it will enable row level consistent read (Row CR) if either of the following are true:

Event 10313 is enabled
