Status: Closed |
DB2 REPORTS NUMBER OF PROCESSOR CORES WITH INTEL HYPERTHREADING INCORRECTLY (CONTINUATION OF IC81317 ) |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
Apar IC81317 not completely fixed.
DB2 on a HP server with two Intel(R) Xeon(R) CPU E5-2665 with 8
cores each, in sum 16 cores.
Hyperthreading is activated so DB2 sees 32 cores on a Windows
OS.
The db2diag.log of the server described above shows following
values:
CPU: total:32 online:32 Cores per socket:1 Threading degree per
core:2
Correctly in customers view would be:
CPU: total: 2 online: 2 Cores per socket:8 Threading degree per
core:2
In summary this is the third attempt to display the correct CPU
information.
- db2diag.log :
Instance "DB2" uses "64" bits and DB2 code release "SQL09076"
with level identifier "08070107".
Informational tokens are "DB2 v9.7.600.413", "s120516",
"IP23323", Fix Pack "6".
