Buffer pool requirements

Due to the large size of tables in Product Master, the page size that is used to create the buffer pools is 16 KB and 32 KB.

You must create the buffer pools, and stop and restart the DB2® instance, before you create the table spaces.

The following table lists the buffer pools that are needed for use by table spaces and the size for each buffer pool:
