要解决这个问题，可以减少主缓冲池的大小。
To resolve this problem, reduce the size of main buffer pools.
这样，一旦主缓冲池无法启动，DB 2还可以使用这些小型的缓冲池来启动数据库。
Should the main buffer pools fail to start, DB2 will start the database with the small buffer pools.
如果主缓冲池配置得太大，则可能出现主缓冲池不适合可寻址内存空间的情况。
When the main buffer pools are configured too large, it is possible that they will not fit into the addressable memory space.
