达梦数据库设置最大连接数

1. 查看最大连接数

SQL> select SF_GET_PARA_VALUE(2,'MAX_SESSIONS');

LINEID SF_GET_PARA_VALUE(2,'MAX_SESSIONS')
---------- -----------------------------------
1 10000

used time: 0.917(ms). Execute id is 56302.

2. 修改最大连接数（1000）

SQL> ALTER SYSTEM SET 'MAX_SESSIONS' = 1000 spfile;
DMSQL executed successfully
used time: 5.609(ms). Execute id is 56303.

　　 修改连接数配置后，重启数据库服务生效。
