Db2 for z/OS

REORG with a new keyword should transfer the page set work to DFDSS

Why is the above idea useful? Sometimes you need to move page sets around due to altering the HLQ, due to removing extents etc. These actions do not require an unload and reload of the data, because it is external stuff out of DB2 scope. For small...

UDF INTERPRET should accept any CCSID

The built-in function INTERPRET added with FL505 should also support CCSIDs other than the CCSID of the Db2. For example, it should be possible to convert data in a Db2 with CCSID 1141 to CCSID 1141, provided the source data is defined with FOR BI...

Db2: V13 Access Path regression: Tablespace scan regresses to nonmatching index scan. After turning this in as a problem, we were told that it was working as designed. Our suggestion is that the design is flawed.

We feel the design is flawed and strongly feel this is a bug. The only time a non-matching index scan should be considered versus the tablespace scan is when it can at least filter the result somewhat. There are ZERO columns in the index that matc...
