oracle install 11gR2 RAC 运行root.sh时出现missing CAP_NUMA_ATTACH 问题

今天一个同事在项目中实施oracle 11gR2 rac for aix 的安装时,安装到需要在节点上运行root.sh
时出现以下问题:
Creating /etc/oratab file...
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.

User oracle is missing the following capabilities required to run CSSD in realtime:
CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE
To add the required capabilities, please run:
/usr/bin/chuser capabilities=CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE oracle
CSS cannot be run in realtime mode at /grid/crs/install/crsconfig_lib.pm line 8119.

解决方法:
usr/bin/chuser capabilities=CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE oracle

再次运行root.sh时,提示运行/grid/crs/install/rootcrs.pl -deconfig 脚本

报错,运行不成功

看来前期安装的准备工作非常重要,而在官方文档中明确列出在安装前对oracle用户赋予以下属性

usr/bin/chuser capabilities=CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE oracle

因为是新环境,所以用deinstall 命令铲掉环境后,对oracle用户增加上面属性后,运行root.sh脚本成功
安装grid非常顺利
