11.2.0.3 RAC IO问题

1^#

发表于 2012-5-4 15:26:25 | 查看: 8639| 回复: 11

环境: Linux5.6 x64+11.2.3 RAC
现状: GI和Oracle已经安装完毕, RDBMS实例暂未创建, CRS一旦启动, kjournald  IO就上去了, 主机响应非常慢, 未解决!

(1), 查询结果,sda2写很频繁.

(2), 进程占用io查询, 发现kjournald一直很高.

(3), 将CRS disable后, 主机IO正常.
这个问题你怎么看, 给点提示呢? 需要什么数据我可以贴给你.谢了!

该虚拟主机的物理内存不超过2G ， 11gR2 RAC 推荐配置至少4g 内存，在物理内存较小的情况下会发生大量的换页SWAP ， swap本身会导致 kjournald IO

建议你提高虚拟主机的性能配置

Mac, 我增大内存到2GB, 完全没有好转, 没能决这个问题, 不知道是不是主机配置太低了导致的,我打算改用32位的试试看.

安装 11gR2 RAC host memory 至少准备 3GB ，最好是 4GB以上否则安装不成功或者安装完了系统负载很高都属于正常现象。
