Tables/Index (Range MQ MDC etc.)

Reorg: detailed information about Reorg incluiding a time/percent prediction to complete the all process

There is no way to find out how long the Reorg process or some steps will take, specially for big tables.

List Partitioning

Allow to partition a table using a list of values (known as list partitioning).

Block locking for U/D on MDC when LOCKSIZE=BLOCKINSERT

Block locking is done for INSERTs on MDC tables when LOCKSIZE = BLOCKINSERT, which is a great benefit for memory usage, and allow to parallelize treatments for different dimensions. However, this is unsufficient, because treatments do also Update/...

Wrap tables

Create a new type of table based on the size or on the time.create table packagevent (.... ) with history based 1 year on event_timestamp / 1Gb. It could be an ITC table. The oldest data / extent are automatically reused when new data is added and...

UNIQUE INDEXES over BIGINT column can't be compressed

unique indexes over id columns (bigint) are not compressed whereas the same unique index over decimal column gets compressedindex compression for unique indexes is urgently needed to reduce disk and memory footprint

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...

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...

Creation of range-partitioned tables during TRANSPORT

Whilst working on a recent pureScale POC with a customer, we came to the stage of upgrading their existing database to pureScale. Existing database had a catalog SMS tablespace. pureScale has a requirement that all tablespaces have to be AUTOMATIC...

Declarative RI for Db2 LUW Bitemporal tables

it would be good to implement Bi-temporal Period Containment with declarative RI in Db2 LUW
