This APAR includes the complete fix for IC81317. 
DB2 on a HP server with two Intel(R) Xeon(R) CPU E5-2665 with 8 
cores each, in sum 16 cores.

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 
 
 
The correct output should be: 
 
 
 
CPU: total: 2 online: 2 Cores per socket:8 Threading degree per 
core:2
