aix平台tab$被删除可能出现ORA-600 [16703], [1403], [28]错误

发表于 2020 年 4 月 4 日 由 惜分飞

以前在恢复过程中遇到过ORA-00600: internal error code, arguments: [16703], [1403], [28]错误(10g数据库遭遇ORA-600 16703)以为是因为10g版本的tab$记录被删除的原因导致报错和最常见的ORA-00600: internal error code, arguments: [16703], [1403], [20]不完全一致(警告：互联网中有oracle介质被注入恶意程序导致—ORA-600 16703),最近又遇到一个ORA-600 16703 1403 28错误的case,而且数据库版本是11.2.0.4 for aix平台,进一步说明该问题不是由于10g和11g的tab$被删除的区别导致,更多可能是由于操作系统不一样,数据库启动基表访问顺序不一致导致,特此进行说明.
数据库启动成功后报错

对于此类问题,通过分析,确定也是由于DBMS_SUPPORT_DBMONITORP恶意脚本导致tab$记录被删除,导致数据库启动异常,处理方法基本上就是对tab$进行恢复,然后open数据库.
