在每个计算节点上执行此过程，以便将专用域中的 CPU 和内存资源移动到逻辑 CPU 和内存系统信息库中，从而使这些资源可用于 I/O 域。
如果您要闲置核心和内存，请仔细规划。闲置资源并创建 I/O 域后，无法将资源重新移动到专用域中。
在此示例中，在 primary 域中闲置 12 个核心和 1 TB 内存，在 ssccn3-dom1 域中闲置 18 个核心和 1536 GB 内存。
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。
在此示例中，一些资源保持未分配状态，将其闲置。

ssccn3-dom2
ssccn3-dom3
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] c
Step 1 of 2: Core Count
primary : specify number of cores [min: 2, max: 46. default: 18] : 6
you chose [6] cores for primary domain
ssccn3-dom1 : specify number of cores [min: 2, max: 42. default: 30] : 12
you chose [12] cores for ssccn3-dom1 domain
Configuration In Progress After Core Count Selection:
+--------------------------------+-------+--------+-----------+--- MINIMUM ----+
| DOMAIN | CORES | MEM GB | TYPE | CORES | MEM GB |
+---------------------------------+-------+--------+-----------+-------+--------+

+---------------------------------+-------+--------+-----------+-------+--------+
Step 2 of 2: Memory Capacity
(must be 16 GB aligned)
primary: specify memory capacity in GB [min: 32, max: 2048. default: 2048] : 512
you chose [512 GB] memory for primary domain
ssccn3-dom1:specify memory capacity in GB [min: 64, max: 2048. default: 2048] : 1024
you chose [1024 GB] memory for ssccn3-dom1 domain
Configuration In progress After Memory Capacity Selection:

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_16:18:57.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.
