Access osc-setcoremem Log Files

The osc-setcoremem command creates a timestamped log file for each session.

1. Log in as superuser on the compute node's control domain.
2. Change directories to the log file directory and list the contents to get the name of the log file.

   # cd /opt/oracle.supercluster/osc-setcoremem/log
   # ls
    

3. Use a text reader of your choice to view the contents of a log file.

   # more log_file_name

   Example:

   # cat osc-setcoremem_activity_08-28-2015_15\:59\:31.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
    
    primary      : specify number of cores [min: 2, max: 46. default: 12] :
    user input (desired cores): '18'               you chose [18] cores for primary domain
    
    ssccn3-dom1  : specify number of cores [min: 2, max: 30. default: 2] :
    user input (desired cores): '30'               you chose [30] cores for ssccn3-dom1 domain

    |  After the reboot, osc-setcoremem attempts to complete CPU, memory re-configuration. |
    |  Please check syslog and the state of all domains before using the system.           |
    |  eg.,  dmesg | grep osc-setcoremem ; ldm list | grep -v active ; date                |

    Please wait while osc-setcoremem is setting up the new CPU, memory configuration.
    It may take a while. Be patient and do not interrupt.
