Thank you to all who replied - I had well over 30 responses to my query,
therefore I shan't list all the names here, but know that I do appreciate
every reply I received! Several kind souls also sent along sample Oracle
kernel parameter configs,which we shall be reviewing.

My original question was:

>A colleague is installing Oracle on a SPARC, running a recent version of

Everyone who replied indicated that the file to modify is
/etc/system. Many pointed out that a 'boot -r' will then be required to
reconfigure the kernel. It was also suggested that ndd can be used to
change many parameters without the need to reboot.
