Add the hidden attribute for index

Excessive DBHEAP by BLU compression dictionaries

In current design, when SQL statement accesses a table, the compression and expansion dictionaries of that table will be read into DBHEAP and kept there until database deactivation. For column-based table, the memory consumption may up to 100MB. i...

Increase the number of ALTER TABLE operations that can be performed online without placing the table in "reorg pending" state

There are a few operations that seem to place the table into "reorg pending" state immediately when it should be possible to treat them as REORG-recommended. For example, any ALTER COLUMN .. DROP COLUMN statement that doesn't affect indexes should...

Remove The Need To REORG A Table Up On Performing Table Alter/REORG Recommended Operations

Today when we perform certain operations aka REORG recommended operations against a table like adding columns, dropping columns, changing datatype of a column, altering NULLABILITY of a column etc. the table will be put in a state called REORG pen...

Index for a subset of rows

Possibility to index only specific rows of one or more columns. This could be implemented with a WHERE clause in the index create statement and would rsult in a tiny index for exactly the rows you are interested in.

"delete cascade" does not work with "not enforced"

The option "not enforced" on a foreign key invalidates an already set "on delete cascade" option, although this is not visible anywhere within the data model or documentation. In my opinion, setting one of these options should prohibit the other o...

Increase the number of REORG-recommended operations allowed before a full offline reorg must be performed

The current documentations in v11.5 indicate that only 3 units of work containing REORG-recommended operations are allowed. https://www.ibm.com/support/knowledgecenter/SSEPGG_11.5.0/com.ibm.db2.luw.sql.ref.doc/doc/r0000888.html "There can be up to...

Enable compression for LOBs that are not inline

Customer would like non-inline LOBS to also be compressed, as inline LOBs can currently be. Many other datatypes can be compressed and there are many large (up to 20MB) LOBs that are stored outside the table that would not eat up so much space if ...

Real global CGTT (not SESSION local)

SAP BW needs to materialize data into persistent (regular) tables to be able to access it from multiple session (connections). CGTT and DGTT in Db2 cannot be accessed from multiple sessions/connections. Therefore those temp tables that don't requi...
