ORA-600 16703故障,客户找人恢复数据库,数据库被进一步恶意破坏—ORA-00704 ORA-00922---惜分飞

有朋友找到我,数据库报ORA-600 16703错误,这个本来是一个比较常见的破坏故障(警告：互联网中有oracle介质被注入恶意程序导致—ORA-600 16703数据库启动报错如下:

修复tab$启动库报ORA-00704 ORA-00922错误

SQL> alter database Open;
alter database Open
*
第 1 行出现错误:
ORA-01092: ORACLE instance terminated. Disconnection forced
ORA-00704: bootstrap process failure
ORA-00922: missing or invalid option
进程 ID: 1340
会话 ID: 191 序列号: 3

ORA-00704 ORA-00922是比较少见的错误,第一感觉bootstrap$损坏了,对数据库启动过程进行跟踪

进一步分析bootstrap$表记录

通过上述分析,可以确认原库的CREATE TABLE TS$(“TS#”被人修改为CREATE TABLE TS$<“TS#”,通过观察客户机器以及和客户确认,客户找的技术人员上传了bbed工具,并进行了一些操作.基于上述信息,大概率是被人通过bbed工具把TS$(修改为了TS$<,从而使得数据库修复tab$之后也无法正常启动.
