标题:system表空间丢失部分文件恢复

有客户因为system表空间有一个数据文件放在其他位置,当时没有正常拷贝出来(备份了oradata路径下面文件,遗漏了一个system文件),尝试启动库报ORA-01157 ORA-01147等错误

由于11号文件是system表空间的一个数据文件,对于这种数据文件丢失无法offline该数据文件,然后open库(也就是说在open库的时候,system表空间的数据文件必须全部online,如果有部分文件offline就会报ORA-01147).对于这样的情况,以前有过类似恢复经历:bbed打开丢失部分system数据文件库,这次的编写了一个m_scn程序实现快速处理

证明丢失的11号文件(system表空间文件),涉及的对象较少,而且不涉及核心字典,比如tab$,obj$,col$等非常核心对象,评估理论上应该不涉业务数据丢失,尝试直接expdp导出数据,但是很不幸,报ORA-00600: internal error code, arguments: [kdBlkCheckError], [11], [3], [18018]错误

对ORA-600 kdBlkCheckError进行分析分析(11表示文件号,3表示block),是由于导出生成的master表写入在system表空间,而system表空间中的file# 11是人工构造出来的,block 3 是位图分配信息(该信息和实际字典中存储信息不匹配),所以导致出现该错误,对于这个问题解决方法为expdp写master表不在system表空间即可,通过该操作,顺利导出数据,完成本次恢复任务
