The osc-setcoremem command creates a timestamped log file for each session.
# cd /opt/oracle.supercluster/osc-setcoremem/log # ls
# more log_file_name
Example:
# cat /opt/oracle.supercluster/osc-setcoremem/log/osc-setcoremem_activity_10-29-2014_16\:58\:54.log
# ./osc-setcoremem

CPU allocation preference:
1. Socket level
2. Core level
In case of Socket level granularity, proportional memory capacity is
automatically selected for you.
Choose Socket or Core level [S or C]
user input: 'C'
Step 1 of 2: Core count selection
primary : desired number of cores [min: 9, max: 80. default: 16] :
user input (desired cores): '' you chose [16] cores for primary domain
ssccn2-dom1 : desired number of cores [min: 4, max: 68. default: 16] :
user input (desired cores): '22' you chose [22] cores for ssccn2-dom1 domain
ssccn2-dom2 : desired number of cores [min: 4, max: 50. default: 32] :
user input (desired cores): '' you chose [32] cores for ssccn2-dom2 domain
ssccn2-dom3 : desired number of cores [min: 4, max: 22. default: 16] :
user input (desired cores): '8' you chose [8] cores for ssccn2-dom3 domain
ssccn2-dom4 : desired number of cores [min: 4, max: 18. default: 16] :
user input (desired cores): '18' you chose [18] cores for ssccn2-dom4 domain
