更新达梦license

非常简单

cd $DM_HOME/bin
mv dm.key dm.key.bak

上传dm.key到bin目录下

disql
select authorized_customer,expired_date from v$license;

SP_LOAD_LIC_INFO();

再检查视图，如果日期更新说明成功

select AUTHORIZED_CUSTOMER, EXPIRED_DATE, 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' end edition,
case SERVER_type when '1' then 'Official'
 when '2' then 'Test'
 when '3' then 'Trial' end type, 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;

如果没有更新，重启dm数据库
