12C数据库遭遇ORA-600 16703

关于tab$异常的问题,我们在10G(10g数据库遭遇ORA-600 16703),11G(警告:互联网中有oracle介质被注入恶意程序导致—ORA-600 16703)中有发现,近期在12C版本中也发现该问题.再次提醒请注意检查安装介质的md5值和现在运行的库中是否有相关恶意程序
数据库版本

这个错误主要是由于12c的tab$和以前版本比有一些特殊,导致开始恢复不全,通过继续修复tab$之后数据库正常open.

SCN Compatibility问题汇总-2019年6月23日

最近有不少朋友咨询关于2019年6月23日之前数据库scn,数据库是否要升级或者打补丁等问题,这里对相关问题做一个汇总。
1. 是否一定要升级或者打补丁
不一定,以下几种情况可以不用处理
1) 数据库版本11.1.0.7.20+ /11.2.0.3.9+ /11.2.0.4+版本已经包含了该补丁,无需处理
2) 数据库版本全部低于1)中数据库版本
3) 你的数据库环境中不存在1和2中数据库dblink访问
4) 你的数据库环境中有1和2中的数据库dblink访问,但是通过通过dbms_scn设置,不让1中的数据库版本scn compatibility改变(都保持为1)

2. 到了2019年6月23日之后,数据库的scn发生什么改变
简单的说就是数据库每秒可以使用的scn变大了,距离天花板的scn更加大,出现数据库scn用完的概率大大降低

--compat            -- SCN compatibility value
--headroom_in_scn   -- Difference between current SCN and RSL
--headroom_in_sec   -- number of seconds it would take to reachRSL

redhat 7安装Oracle缺少compat-libstdc++

在redhat 7版本中compat-libstdc++-33-3.2.3包被从ISO文件中移除,但是12c及其以后版本安装均需要该包,导致数据库在安装的时候检查无法通过
redhat 7光盘中无compat-libstdc包

通过mos相关描述,该包主要是影响数据库的Oracle Text中的相关功能,如果不使用该功能,可以通过忽略该包继续安装,如果需要使用该功能,可以通过下载compat-libstdc来安装.
参考文档:Missing or Ignored package compat-libstdc++-33-3.2.3 causes Text Issues (Doc ID 2254198.1)
Installation of 12.1.0.2 Oracle Database Server/Client on RHEL 7/OL7 reports pre-requisite package ‘compat-libstdc++’ missing. (Doc ID 2062336.1)
