Because of the large amount of data that can be stored in the OAM object storage tables (the 4 KB object storage table, the 32 KB object storage table and the LOB storage structure) associated with each Object storage group, you might choose to partition the DB2 table spaces containing each of these tables. The 4 KB object storage table, the 32 KB object storage table, and LOB storage structure are each stored in separate DB2 table spaces. You might partition the DB2 table space containing any or all of these tables.
For information about the advantages and disadvantages of partitioned table spaces, see the "DB2 administration" topic in the IBM Information Management Software for z/OS Solutions Information Center.
