Section actuals for BLU

Collecting section actuals and compare it with the SQL compiler estimates using the db2caem tool is quite handy to find cardinality mis-estimates in huge plans.

Performance penalty in LOAD when using large bufferpool

LOAD RESETDICTIONARYONLY and other LOADs take very long, if table resides in large buffer.The limitation also applies to LOAD on row based tables, but bufferpools on BLU systems tend to be much larger.

UPDATE STATISTICS MEDIUM/HIGH with PDQ should favour use of indices for sort when more than one column is specified

Currently (in my testing) any UPDATE STATISTICS MEDIUM/HIGH statement with PDQ specifying more than one column will not use indices for sort and will instead scan the table, write to temporary files and sort. This is true even when all columns spe...

Sort data calculations should not be used to determine number of passes for UPDATE STATISTICS MEDIUM/HIGH statements where an index is used, fix misleading explain output

File Management in PAW

In some use cases for planning it is necessary that a user wants to uploud or share a file for other. It would be helpful if we can offer something like a file explorer in PAW to upload different types of files so that every user can download them...

Db2 LUW Automatic maintenance window setting

Current automatic maintenance does not allow to have multiple offline or online maintenance windows, only one of each. For example, we have automatic online maintenance window for 4 hours at night daily but need to have another definition for 24 h...

Cognos Analytics - Concurrent Query Execution

Cognos Analytics have concurrent query execution setting at server level and report query but it does not work efficiently in most of the case. Concurrent query execution is one of the bigger ask from the customer for better performance.
