To install Oracle Clusterware/Grid Infrastructure using the Oracle Universal Installer

1. Ensure that the Oracle grid user has the following capabilities:

   CAP_NUMA_ATTACH, CAP_BYPASS_RAC_VMM, and CAP_PROPAGATE

   To check existing capabilities, enter the following command as root; in this example, the Oracle grid user is grid:

   # lsuser -a capabilities grid

   To add capabilities, enter a command similar to the following:

   # /usr/bin/chuser \
   capabilities=CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE grid

2. The ncargs attribute controls the maximum command line length, including the environment variables on the AIX nodes. Verify the current value of the ncargs attribute.

   # lsattr -l sys0 -a ncargs -E

   If the value is less than 128, change the attribute to a larger value before invoking the Oracle Installer.

   # chdev -l sys0 -a ncargs=128

3. set DISPLAY varraible

4. execute $GI_HOME/gridSetup.sh as grid
