Managing storage spaceEdit online You can manage aspects of storage space to tune the performance. Understanding automated tablespace adaptationsBackup Object Manager can adapt the sizes of tablespace containers when it creates the containers of the target databases during a redirected restore operation. Normalizing tablespace containers during redirected restoreTo achieve optimal parallel I/O operation performance for a database, all containers of a tablespace are to be the same size. During tablespace maintenance, containers might be added or extended which creates different container sizes. As a result, data is unevenly distributed among the containers, which can result in decreased parallel I/O operation performance during table scans (sequential prefetching). Scaling tablespace containersSufficient free space must be available in a tablespace for the database to function properly. Backup Object Manager provides an automated table space scaling function that allows the location and size of table space container to be redefined. This function also helps prevent I/O-intensive table space rebalancing that can be detected by DB2®.Parent topic: Understanding performance tuning
