oracle install 11gR2 RAC 執行root.sh時出現missing CAP_NUMA_ATTACH 問題

       今天一個同事在專案中實施oracle 11gR2  rac for aix 的安裝時,安裝到需要在節點上執行root.sh

時出現以下問題:

     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.

Creating trace directory
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.

解決方法:

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

再次執行root.sh時,提示執行/grid/crs/install/rootcrs.pl -deconfig 指令碼

-deconfig

報錯,執行不成功

看來前期安裝的準備工作非常重要,而在官方文件中明確列出在安裝前對oracle使用者賦予以下屬性

usr/bin/chuser capabilities=CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE oracle
因為是新環境,所以用deinstall 命令剷掉環境後,對oracle使用者增加上面屬性後,執行root.sh指令碼成功

安裝grid非常順利
