ORA-00600 17182 错误案例一则

ORA-00600 17182 错误的官方解释是：

Oracle has detected that the magic number in a memory chunk header has been overwritten.
This is a heap (in memory) corruption and there is no underlying data corruption.The error may occur in the one of the process specific heaps (the Call heap, PGA heap, or session heap) or in the shared heap (SGA).

也就是说，Oracle检测到内存的错误，可能是因为内存块的覆盖，导致数据损坏或丢失。这个错误可能在进程heap或者SGA中出现，没有潜在的数据损失。

最近有朋友遇到了这个错误，由于这个错误进而产生了一个600G的跟踪文件 --- 这真是我看到的最大的一个跟踪文件。结果当然是空间耗尽，最后数据库因为无法归档而挂起。这个数据库的版本是9.2.0.1，相关错误信息如下：

这个错误也有可能是物理内存的故障所导致，记录一下。
