环境：AIX 6.1+oracle 11.2.0.4.0 双节点RAC
今天发现两个节点的进程数量不一样，一节点很多，二节点很少，且活动的会话一直在一节点，二节点只有一两个活动会话(还是用PL/SQL连接上去的)，如下：
select inst_id 实例编号,
instance_name 实例名,
host_name 主机名,
version 版本,
status 状态,
(select count(*) from gv$process where inst_id = A.inst_id) 进程数,
(select count(*)
from gv$session
where inst_id = A.inst_id
and username = 'CJCL'
and status = 'ACTIVE') 活动会话数
from gv$instance Aorder by inst_id;

我查看了下crs 都处于正常状态：

但就是不知道是什么原因导致这两个节点的负载不均衡，请有经验的兄台指教一下！！！
