实例共享内存是在数据库管理器启动(db2start)时分配的,并随着数据库管理器的停止(db2stop)而释放。
Instance Shared memory is allocated when the database manager is started (db2start), and freed when the database manager is stopped (db2stop).
注意,一些操作系统设置可能会限制可分配的共享内存量,例如Linux上的SHMMAX通常设置为大约20mb。
Note that there are operating system Settings that can limit the amount of Shared memory that can be allocated — for instance, SHMMAX on Linux is typically set to about 20mb.
