[Copy] Support mixed row/column environments without requiring CUR_COMMIT=ON

unique where not null' indexes(RIMS)

Customer requested to open a DCR for 'unique where not null' indexes. Can this done? This feature exists in DB2 zOS but not in DB2 LUW. This DCR is already opened for another customer in the US, but as far as I know, it's not possible to 'vote' fo...

Enforce index name uniqueness at table level; not at schema level(RIMS)

currently all index names for a partiuclar schema must be unique. This is painful when there are tens of thousands of indexes. They want to be able to use duplicate schema names as long as the name is unique per table that the index is defined on.

Utility to increase a tablespace's page size(RIMS)

DB2 registry variable granularity(RIMS)

Ability to specify object table and space map rules at a tablespace level (example, DB2_OBJECT_TABLE_ENTRIES at tablespace level).

display/report size of individual Index (not whole index object)(RIMS)

At present the size of an index is reported only in aggregate for all indexes on a table. It would be ideal to know the actual index size in bytes per individual index;
