The CREATE BUFFERPOOL statement defines a new buffer pool to be used by the database manager.
In a partitioned database, a default buffer pool definition is specified for each database partition, with the capability to override the size on specific database partitions. Also, in a partitioned database, the buffer pool is defined on all database partitions unless database partition groups are specified. If database partition groups are specified, the buffer pool will only be created on database partitions that are in those database partition groups.
