在网上看到一个案例UNDO tablespace被误删除,并且shutdown abort数据库.然后再启动数据库都会报下面的错：

ORA-1092 : opitsk aborting process

下面是尝试解决方法：

1.发现在执行recursive SQL level 1的时候报错,所以我们需要通过10046看看在执行什么sql报错的

alter session set events  ’10046 trace name context forever,level 12′;
alter session set db_file_multiblock_read_count=1;

alter database open;然后会生成一个tracefile

2.tracefile内容

在上面你可以看到在读到file1,block 705,665的时候报错,应该是里面有未提交的事物,下面就可以通过bbed来简单的修复

3.通过bbed来修复,需先找一个原datafile 1的文件
