Oracle Parameters on Solaris 10

With the availability of the Solaris 10 operating system, the way IPC facilities (e.g., shared memory, message queues, etc.) are managed changed. In previous releases of the Solaris operating system, editing /etc/system was the recommended way to increase the values of a given IPC tunable. With the release of Solaris 10, IPC tunable are now managed through the Solaris resource manager. The resource manager makes each tunable available through one or more resource controls, which provide an upper bound on the size of a given resource.
