- The sysctl -a | grep semresult showed the semopm parameter value as 32, which is less than the required value of 100. So the line kernel.sem = 240 32000 100 128 was added to /etc/sysctl.conf
- The sysctl -a | grep shmresult was initially interpreted as valid. Later the installer complained that the shmmax parameter value of 33554432 was less than the required 2147483648, which is supposed to be half the size of physical memory in bytes. So the line kernel.shmmax = 2147483648 was added to /etc/sysctl.conf. The size of physical as reported by /proc/meminfo is 1027396 kB or 1052053504 bytes, half of which is 526026752. Thre is a discrepancy here.
- The sysctl -a | grep file-max result is valid.
- The sysctl -a | grep ip_local_port_rangeresult showed the range to be 32768 to 61000, which is different than the required range of 1024 to 65000. So the line net.ipv4.ip_local_port_range = 32768 65000 was added to /etc/sysctl.conf. The lower limit of 32768 was left to satisfy the stipulation that if any existing value is higher than the required value, the existing value is to be left unchanged.
