AIX Oracle RAC 升级到10.2.0.4.0要特别注意的问题

AIX Oracle RAC 升级到10.2.0.4.0过程有如下报错(直接升级到10.2.0.4不需要应用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 <oracle> to have the following OS capabilities :
<CAP_BYPASS_RAC_VMM CAP_PROPAGATE CAP_NUMA_ATTACH >
by running </usr/bin/chuser> 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

# 未对这个错误做处理也能正常的运行Oracle RAC。但是在errpt -a中会出现以下报错

另外根据有些文章所说，在AIX平台Oracle RAC升级到10.2.0.4.0之后，如果要将sga_lock设置为TRUE。也需要做同样的处理，否则在设置sga_lock=TRUE之后启动会报错：
SQL> startup
ORA-27126: unable to lock shared memory segment in core
IBM AIX RISC System/6000 Error: 1: Not owner

根据报错，以上的2种情况都需要做如下处理：
chuser capabilities=CAP_BYPASS_RAC_VMM,CAP_PROPAGATE,CAP_NUMA_ATTACH oracle
#lsuser -a capabilities oracle

设置完成后重启以下CRS服务即可。
