Replication
For replication, TCP send and receive buffers should be increased to a
minimum of 512KB. You may need to embed the following commands
into a script that can be run at system boot time:
# /sbin/sysctl -w net.ipv4.tcp_rmem="4096 4194304 4194304"
# /sbin/sysctl -w net.ipv4.tcp_wmem="98304 4194304 4194304"
# /sbin/sysctl -w net.ipv4.tcp_mem="98304 4194304 4194304"
# /sbin/sysctl -w net.core.rmem_default=65535
# /sbin/sysctl -w net.core.wmem_default=65535
# /sbin/sysctl -w net.core.rmem_max=4194304
# /sbin/sysctl -w net.core.wmem_max=4194304
# /sbin/sysctl -w n et.ipv4.tcp_window_scaling=1
Cache
Connect
For Cache Connect, TCP send and receive buffers should be increased
to even greater values. You may need to embed the following
commands into a script that can be run at system boot time:
# /sbin/sysctl -w net.ipv4.tcp_rmem="4096 4194304 4194304"
# /sbin/sysctl -w net.ipv4.tcp_wmem="98304 4194304 4194304"
# /sbin/sysctl -w net.ipv4.tcp_mem="98304 4194304 4194304"
# /sbin/sysctl -w net.core.rmem_default=262144
# /sbin/sysctl -w net.core.wmem_default=262144
# /sbin/sysctl -w net.core.rmem_max=4194304
# /sbin/sysctl -w net.core.wmem_max=4194304
# /sbin/sysctl -w net.ipv4.tcp_window_scaling=1
# /sbin/sysctl -w net.ipv4.ip_local_port_range="1024 65000"

IPC
semaphores
On Solaris 8 and 9, TimesTen checks the IPC configuration at install
time. If either the IPC Semaphores module or the IPC Shared Memory
module is not installed, you can install them by hand. Use the
