Add the following lines to the "/etc/sysctl.conf" file.

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default=262144

net.core.rmem_max=262144

net.core.wmem_default=262144

net.core.wmem_max=262144

Run the following command to change the current kernel parameters.

/sbin/sysctl -p

Then restart SAPINST

Can you set the following in limits.conf

soft nofile 131072

hard nofile 131072

soft nproc 131072

hard nproc 131072

soft core unlimited

hard core unlimited

soft memlock 50000000

hard memlock 50000000

Then try to start SAPINST from a new session.
