如何完全删除CRS OS:Red Hat Linux As 5DB:10.2.0.1   在安装好CRS后发现CRS无法启动,每次CRS启动异常都导致机器不停的重启动,超级郁闷,获取日志信息如下:2012-08-01 11:50:18.491: [ CSSCLNT][5177872]clsssInitNative: connect failed, rc 92012-08-01 12:15:47.441: [ CSSCLNT][5547712]clsssInitNative: connect failed, rc 92012-08-02 09:03:11.045: [ CSSCLNT][9479872]clsssInitNative: connect failed, rc 9  网上说引起这个问题的原因很多,能找到的办法都尝过了,问题依旧,最后回想想第一次安装CRS后不成功,可能是没有完全删除导致的,最后在网上找到了一份完全删除CRS的方法,按照这个方法完全删除后重新安装CRS,问题解决. 1. Run the rootdelete.sh script. then the rootdeinstall.sh script. from the$ORA_CRS_HOME/install directory on any nodes you are removing CRS from.  Runningthese scripts should be sufficent to clean up your CRS install.  Rootdelete.shaccepts options like nosharedvar/sharedvar, and nosharedhome/sharedhome. Makeyourself familiar with these options by reading the Oracle C...

How to install ASMLIB from Oracle’s public YUM   http://oracleexamples.wordpress.com/2011/08/08/how-to-install-asmlib-from-oracles-public-yum/There are several ways to get ASMLIB, we can download it from the OTN here, or http://www.oracle.com/technetwork/topics/linux/asmlib/index-101839.html ,or we can download it from from ULN (Unbreakable Linux Network).Also it comes in the the Unbreakable Linux media, but if you are not subscribed to ULN and you are not using Unbreakable Linux then most people go to the OTN, where you have to select your Linux flavor and then navigate to the correct file according to the linux kernel and then download the 3 files one by one.I’m going to explain here how easy is to get it from Oracle’s public YUM repository (how to configure the public YUM repository?)Once you have the public YUM enabled do as root:1yum install o...

centos ssh无密码互信登录失败解决方法 最近使用RAC时，需要ssh无密登录， 配置好后，一直主机正常，另外一台，必需要密码才能登陆。配置ssh互信方式 都一样，却有一个主机有问题。后来发现， Oracle 用户家目录权限，不一样。# chmod 775 /home/oracle然后，就可以正常使用了。
