Enhancement of compression algorithm used by DB2

We have noticed that the compression ratio (PAGESAVE) for first partition of a Partitioned TS is 0% after running an IBM Reorg Utility. The reason why PAGESAVE/compression ratio for that first Partition is 0% is caused because many initial rows in...

Add catalog information about how a compression dictionary was created (INSERT, LOAD, REORG)

Db2 is able to create a compression dictionary by INSERT, LOAD and REORG. If INSERT and LOAD are responsible, than the first x rows were not compressed (Db2 reads them to build a proper dictionary). If REORG is responsible for creating a compressi...

LOAD with DISCARDS 1 should not require a discard data set

We wanted to load two partitions at partition level: //LOA001 EXEC #DB2UT, // SYSTEM=T, // SYSTEMID=L, // COND=(4,LT), // SYSUT1=Y, // LARGE=Y, // SAR=N //SYSREC01 DD DISP=SHR,DSN=VTDBM.UL.VETB0040.REC.PART1 //SYSREC02 DD DISP=SHR,DSN=VTDBM.UL.VET...

Avoid impact from query sort usage on more important online transactions workload

Nowadays usage of Sortworks by a single thread is limited by MAXTEMPS or the size of the overall available sortworks if MAXTEMPS is zero. Most time MAXTEMPS works well to protect our regular business against single queries with a lot of sort amoun...

Add flag field to IFCID 402 to indicate when a reset has occurred.

In Db2 Version 13 and V12 (with APAR PH50729), Db2 resets IFCID 402 statistic counters immediately if the warning or exception threshold for the associated profiles is changed when you issue a START PROFILE command. It’s difficult to tell if the c...

Allow system administrators to specify bufferpool sizes in "M" or "G", rather than pages.

With big memory and bufferpools measured in gigabytes, sizing pools by number of pages becomes tedious and error-prone. A 1GB pool requires one to specify -ALT BPOOL(BPx) VPSIZE(262144). A 5GB pool would be VPSIZE(1310720). Most users use "round" ...

Add SET CURRENT QUERY ACCELERATION WAITFORDATA setting into Profile Table in Db2 for z/OS

When Waitfordata setting is required for HTAP queries in IDAA for dynamic SQLs, waitfordata should be defined either in zPARM or as a register setting in application before the SQL statement which requires application change. It would be better to...

DSN1COPY to support LOB INLINE COPY as input

More than 80% of our data consist of LOB data. In case of drop recovery we depend on utilities such as DSN1COPY. Without this feature provided DSN1COPY cannot be used for drop recovery when we have to use a LOB INLINE COPY as input.
