达梦许可license 检查

为了确认拿到的dm.key是否是所需的，需要检查，否则可能因为平台、cpu个数、支持功能范围而导致出现问题（加载失败、cpu无法全部利用、搭建dw失败等）

select SERIES_NO,AUTHORIZED_CUSTOMER, isnull(to_char(EXPIRED_DATE),'for ever') yxq, 
case SERVER_SERIES when 'P' then 'Personal'
 when 'S' then 'Standard'
 when 'E' then 'Enterprise'
 when 'A' then 'Security'
 when 'D' then 'Developer'
 when 'C' then 'Cloud' 
 else 'Other' end edition,
case SERVER_type when '1' then 'Official'
 when '2' then 'Test'
 when '3' then 'Trial' 
 else 'Unknown' end type, 
MAX_CORE_NUM,server_ver,
case substr(CLUSTER_TYPE,1,1) when '1' then 'YES' else 'NO' end DW,
case substr(CLUSTER_TYPE,2,1) when '1' then 'YES' else 'NO' end MPP,
case substr(CLUSTER_TYPE,3,1) when '1' then 'YES' else 'NO' end RW,
case substr(CLUSTER_TYPE,4,1) when '1' then 'YES' else 'NO' end DSC
from v$license;

效果如下：
