The common solution to this problem is to store the session in a database instead of memory.

此问题的常用解决方案是，把会话存储在数据库而不是内存中。

youdao

Limit: Any request by DB2 to create a database share memory set which is larger then the shmmax value (2gb in this case) will fail with an out of memory type error.

限制：DB2发出的任何创建大于shmmax值(这里是2gb)的数据库共享内存集的请求都将失败，并返回一个out of memory type错误。
