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...

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。

RedHat(RHEL)6 support ASMLIB (RHEL6支持asmlib) With the annoucement of Oracle’s database support on RHEL6 and OEL6, they have decided to stop making ASMLIB for RHEL compatible kernels. ASMLIB is now only available if you are using Oracle Unbreakable Linux Kernel. RHEL6 has also deprecated the use of setting LUN permissions using multipath.conf therefore we have to fall back to UDEV rules. Recent events enabled Red Hat and Oracle to work together, and Oracle is now officially supporting ASMlib on Red Hat Enterprise Linux 6.4 and newer. ORACLE sound: All ASMLib installations require that the ‘kmod-oracleasm’,'oracleasmlib’ and ‘oracleasm-support’ packages be installed on the system. The ‘oracleasmlib’ and ‘oracleasm-support’ packages are available for download at the locations listed below. The kernel driver package ‘kmod-oracleasm’ is available directly fro...

RHEL6 虚拟机克隆网络问题解决方法   环境：Virtualbox+RHEL 6 x64用VirtualBox的vboxmanager克隆的虚拟机，操作系统RHEL6，启动后发现网卡不能用了。重启网络服务，报以下错误:Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization.   [FAILED]在RHEL5里也发生类似事情，因为复制虚拟机MAC会重新生成，但是操作系统的MAC却写在ifcfg-ethx里，造成了不一致，所以不能启动网络接口，在RHEL5里可以使用kudzu或者注释网卡配置文件的MAC字段来解决这个问题。但是在RHEL6里，kudzu已经被hal服务取代了。虽然lspci能够正常认到网卡，但是却无法使用/etc/init.d/network restart来启动服务。尝试注释ifcfg-eth0的MAC字段，还是报错。查看了下udev的规则，发现了问题的所在。[root@Oracle ~]# cat /etc/udev/rules.d/70-persistent-net.rules # This file was automatically generated by the /lib/udev/write_net_rules# program, run by the persistent-net-generator.rules rules file.## ...
