AIX Oracle RAC 升級到10.2.0.4.0要特別注意的問題

AIX Oracle RAC 升級到10.2.0.4.0過程有如下報錯(直接升級到10.2.0.4不需要應用Patch:6160398)：
root@bwgl_db2:/u01/app/oracle/crs_1/bin# /u01/app/oracle/crs_1/install/root102.sh
Error : Please change the CRS_ORACLE_USER id to have the following OS capabilities :
 
by running command then 'crsctl stop crs' and 'crsctl start crs'.
The CSS daemon, ocssd.bin, will not run in realtime without  this change
Oracle strongly recommends that the CSS daemon run realtime
Creating pre-patch directory for saving pre-patch clusterware files

未對這個錯誤做處理也能正常的執行Oracle RAC。但是在errpt -a中會出現以下報錯：

另外根據有些文章所說，在AIX平臺Oracle RAC升級到10.2.0.4.0之後，如果要將sga_lock設定為TRUE。也需要做同樣的處理，否則在設定sga_lock=TRUE之後啟動會報錯：
SQL> startup
ORA-27126: unable to lock shared memory segment in core
IBM AIX RISC System/6000 Error: 1: Not owner

根據報錯，以上的2種情況都需要做如下處理：
#chuser capabilities=CAP_BYPASS_RAC_VMM,CAP_PROPAGATE,CAP_NUMA_ATTACH oracle
#lsuser -a capabilities oracle

設定完成後重啟以下CRS服務即可。
