在每个计算节点上执行此过程，以在插槽粒度级别更改该节点的 CPU 和内存资源分配。
该工具进行以下更改：
自动检测根域。
计算所有域的最小和最大资源量，使您仅能够选择有效的数量。
根据您的选择修改域资源。
自动按照与 CPU 资源相同的比例分配内存容量。
（如果需要）停止非主域。
（如果需要）重新引导具有新资源的主域。
（如果需要）初启具有新资源的非主域。
在此示例中，从 primary 域中删除了一个插槽和 1 TB 的内存并将其分配给 ssccn3-dom1。
下表显示了分配规划（请参见Plan CPU and Memory Allocations）。
|
如果存在任何非活动域，则该工具将无法继续运行。
出现提示时进行响应。按 Enter 键以选择默认值。

CPU allocation preference:
1. Socket level
2. Core level
In case of Socket level granularity, proportional memory capacity is
automatically selected for you.
Choose Socket or Core level [S or C] s
Step 1 of 1: Socket Count
primary : specify socket count [min: 1, max: 3. default: 1] : 1
you chose [1] socket for primary domain
ssccn3-dom1 : specify socket count [min: 1, max: 3. default: 1] : 3
you chose [3] sockets for ssccn3-dom1 domain
Configuration In Progress After Socket Count Selection:
+----------------------------------+----------+----------+-----------+
| DOMAIN | SOCKETS | MEM GB | TYPE |
+----------------------------------+----------+----------+-----------+
| primary | 1 | 1024 | Dedicated |
| ssccn3-dom1 | 3 | 3072 | Dedicated |
| *ssccn3-dom2 | 0.083 | 16 | Root |
| *ssccn3-dom3 | 0.167 | 32 | Root |

Following domains will be stopped and restarted:
ssccn3-dom1
This configuration requires rebooting the control domain.
Do you want to proceed? Y/N : Y
+- IMPORTANT NOTE: -+
| After the reboot, osc-setcoremem attempts to complete CPU, memory re-configuration. |
| Please check syslog and the state of all domains before using the system. |
| eg., dmesg | grep osc-setcoremem ; ldm list | grep -v active ; date |
+- -+
All activity is being recorded in log file:
/opt/oracle.supercluster/osc-setcoremem/log/osc-setcoremem_activity_08-28-2015_15:31:27.log
Please wait while osc-setcoremem is setting up the new CPU, memory configuration.
It may take a while. Be patient and do not interrupt.
