Indexes (for same table) into separate objects(RIMS)

Customer would like to have indexes (for the same table) stored into separate objects. This would provide the ability to rebuild/reorg/manage a single index, which can help shorten the duration of these maintenance operation and also reduce the ac...

Victimization of unused compression dictionaries from DBHEAP(RIMS)

Compression and Expansion dictionaries for each object (table, index) remain in memory until database deactivation time. This is problematic because enough DBHEAP must be allocated to host a compression/expansion dictionary for EACH object that is...

Parallel index creation for partitions of a partitioned-table(RIMS)

[JPMC EDW] Currently, a create-index statement with the PARTITIONED clause will process each partition sequentially. Ideally DB2 would perform this with some degree of parallelism. Currently, this can be accomplished by detaching the individual pa...

way to make 'COMPRESS YES' the default for all CREATE TABLE/INDEX statements.(RIMS)

Customer would like a means to be able to make 'COMPRESS YES' the default behaviour for CREATE TABLE and CREATE INDEX statements. Since the customer's enterprise-data-warehouse database is used by many vendor applications, it's onerous to modify v...

A REBALANCE utility that rebalances container maps (rather then filling in gaps)(RIMS)

The current REBALANCE utility actually moves extents around from higher stripes to lower stripes to fill in gaps of empty extents. This means that containers are not necessarily 'balanced' (ie. contain the same number of extents) at the end of the...

Ability to report Bufferpool contents(RIMS)

Ability to display contents of a Bufferpool to aid in performance-related investigations.

Change buffperpool minimum size(RIMS)

We are looking into some performance issues so earlier I was looking at the STMM log on one of our servers for a bufferpool, below, and was wondering if there is a way to change the minimum size value. ... it would be really nice if we could force...

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;

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).

wait-for-delay functionality (server side sleep without spinning CPU)(RIMS)

Customer requests the ability to add a server-side sleep function that does not consume CPU or require an external routine. Such a routine would be useful in that it can be added to an SQL procedure to perform a sleep/delay, without having to intr...
