AIX世界中Capabilities做何理解?
 
 Recommended OS Capabilities for CRS User to run Oracle Clusterware software

Oracle recommends CRS User to have CAP_NUMA_ATTACH, CAP_BYPASS_RAC_VMM, and CAP_PROPAGATE OS capabilities when running Oracle clusterware software.

To check existing capabilities, enter the following command as root; in this example, the Oracle Clusterware oracle user is crs:
 # /usr/sbin/lsuser -a capabilities crs

To add capabilities, enter a command similar to the following:
 # /usr/bin/chuser capabilities=CAP_NUMA_ATTACH CAP_BYPASS_RAC_VMM CAP_PROPAGATE crs

Repeat this procedure on all of the other nodes in the cluster.
