Platform : IBMAIX 6.1
GRID and RDBMS version : Oracle 11gR2
Pre-req steps:
1) Ensure all required /etc/hosts entries are done on all nodes for private IP , Public IP , VIP and Scan IPs (with required scan_name).
2) Create dba group on all RAC nodes with same uid.
3) Create oracle group on all RAC nodes with same gid.
4) Set ulimit (shell limits) to unlimited for all parameters.
5) Ensure following IPS are available before starting RAC installation.
a) Public IP (Pingable)
b) Private IP (Pingable)
c) Virtual IP (not pingable before installation)
d) 3 Scan IPs (not pingable before installation)
6) Set following OS parameters. Run below commands as root.
/usr/sbin/no -p -o udp_sendspace=65536
/usr/sbin/no -p -o udp_recvspace=655360
/usr/sbin/no -p -o tcp_sendspace=65536
/usr/sbin/no -p -o tcp_recvspace=65536
/usr/sbin/no -p -o rfc1323=1
/usr/sbin/no -p -o sb_max=4194304
7) Ensure oracle user has following capabilities.
CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE
If not , user below command as root to add the capabilities
