Problem IC85355
|
Status: Closed |
Performance degeneration with API db2GetRowPartNum |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
If db2GetRowPartNum function is called, then performance
degeneration can be observed directly without any other trigger
points.
DB2 changed variable DB2_RUNTIME_DEBUG_FLAGS from default
static to support -IMMEDIATE option which will make the variable
to behave as dynamic when this option is supplied. Reading
dynamic variable from client is expensive and this leads to
performance degeneration. |
