Oracle 11g丢失access$恢复方法
11.1.0.7版本也会出现access$表丢失导致数据库无法启动
总结主要两类:1. 由于某种bug导致access$表丢失的故障,另外一种是由于坏块导致数据库核心基表损坏引起,对于这个库进行分析

dbv 检查坏块

ORA-00704: 引导程序进程失败

通过这一步基本上可以判断是由于obj$表丢失导致数据库创建I_OBJ1 index不成功,从而使得数据库无法正常启动。通过一些技巧修复出来obj$表,尝试启动数据库

datafile-header
logfile

通过这里可以看出来,数据库需要的redo确实是721,但是recover无法应用成功,出现该问题的原因是由于控制文件信息不对导致

使用备份控制文件恢复

下调虚拟化资源导致ORA-00494

发表于 2018 年 11 月 27 日 由 惜分飞

在虚拟化环境中的Oracle数据库近期报大量ORA-00494: 入队 [CF] 被持有的时间过长 (more than 900 seconds) 错误,每次客户重启一段时间之后又不行

因为这个系统有一段历史,以前是客户的核心生产库,虚拟化资源给的比较多128G,后来核心生产迁移到其他系统,该系统跑一些边缘小业务,所以怀疑客户有可能下调了虚拟化的资源(cpu和内存),检查机器硬件资源

果然系统内存从128G下调到了32G,但是数据库sga估计没有对应降低

SQL> show parameter sga;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------
lock_sga                             boolean     FALSE
pre_page_sga                         boolean     FALSE
sga_max_size                         big integer 80G
sga_target                           big integer 80G

基本上就是由于虚拟机内存下调,但是数据库sga配置过大导致该问题.
