The osc-setcoremem command creates a timestamped log file for each session.
# cd /opt/oracle.supercluster/osc-setcoremem/log # ls
# more log_file_name
For example:
# cat osc-setcoremem_activity_08-28-2015_15\:59\:31.log # ./osc-setcoremem osc-setcoremem v2.0 built on Aug 27 2015 23:09:35 Current Configuration: SuperCluster Fully-Populated M6-32 Base +----------------------------------+-------+--------+-----------+--- MINIMUM ----+ | DOMAIN | CORES | MEM GB | TYPE | CORES | MEM GB | +----------------------------------+-------+--------+-----------+-------+--------+ | primary | 12 | 1024 | Dedicated | 2 | 32 | | ssccn3-dom1 | 36 | 3072 | Dedicated | 2 | 32 | | ssccn3-dom2 | 1 | 16 | Root | 1 | 16 | | ssccn3-dom3 | 2 | 32 | Root | 2 | 32 | +----------------------------------+-------+--------+-----------+-------+--------+ | unallocated or parked | 45 | 4048 | -- | -- | -- | +----------------------------------+-------+--------+-----------+-------+--------+ [Note] Following domains will be skipped in this session.
