Tables/Index (Range MQ MDC etc.)

Showing 93

Index for a subset of rows

Ability to configure threshold for trigger to automatic resize(RIMS)

Some IT service providers for the financial industry in Germany have a high degree of automation. They are using AUTORESIZE for tablespaces. Unfortunately, the threshold cannot be specified and DB2 only extends the tablespace when it is full. In s...

Hybrid Indexes(RIMS)

I recently inquired with IBM regarding what I am calling hybrid indexes, ie: indexes that reference normal columns as well as nodes within an XML column. This is not currently available, however, in the communications Melanie requested that I pass...

Add functionality during database migration to allow existing tablespaces to be reduced automatically(RIMS)

In V9.7, the internal structure of a tablespace has been slightly changed to allow a better way to reduce its space when it is no more needed. This is externalized by a new option in the 'ALTER TABLESPACE' command : 'REDUCE [MAX]' The point is tha...

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