今天有人问我这样之后能不能恢复, 我想基本上已经不能了. 在open时报ORA-01092号错误, 我查了一下event也没有这方面的合适的event啊, 我推荐用不完全恢复, 不过好象是没有备份, 运行在noarchivelog模式.
从trc文件中得到的内容:
KCRA: buffers claimed = 0/0, eliminated = 0
ORA-00704: bootstrap process failure
ORA-00604: error occurred at recursive SQL level 1
ORA-01502: index 'SYS.I_DEPENDENCY1' or partition of sUCh index is in unusable state
oerr ora 704
00704, 00000, "bootstrap process failure"
// *Cause:Failure in processing bootstrap data - see accompanying error.
// *Action: Contact your customer support representative.
SQL_TRACE打开的情况下生成的Trace:

DBA做事一定要细心, 在运行批处理时一定要审了再审.
