DB2 LUW Storage Manager (Revision #7)

With Aqua Data Studio 7.5 you can plan, initialize, allocate, manage, and tune IBM DB2 UDB database objects for better performance

New enhanced Object Tab in Aqua Data Studio 7.5 gives:

• Detailed information of Segments
• High-level storage information of Tables which helps in tracking growth
• Index storage that now includes Index Type, Size, Rows, Validity and Created Date. You can quickly identify whether indexes are not created on Tables participating in SQL Queries
• Overall Object Storage information. You can sort and quickly identify which Table or Index takes up more space. You can configure Storage and eliminate wasted storage

Object Tab - Display of the Tables and Indexes.
