Format of This Appendix

The rest of this appendix describes the more important tunable parameters according to function. Related parameters are grouped into sections. These sections include:

General tunable parameters. See "General Parameters".
System limits tunable parameters. See "System Limits Parameters".
Resource limits tunable parameters. See "Resource Limits Parameters".
Paging tunable parameters. See "Paging Parameters".
IPC tunable parameters-including interprocess communication messages, semaphores, and shared memory. See "IPC Parameters", "IPC Messages Parameters", "IPC Semaphores Parameters", and "IPC Shared Memory Parameters".
Streams tunable parameters. See "Streams Parameters".
Signal parameters. See "Signal Parameters".
Dispatch parameters. See "Dispatch Parameters".
Extent File System (EFS) parameters. See "EFS Parameters".
Loadable driver parameters. See "Loadable Drivers Parameters".
CPU actions parameters. See "CPU Actions Parameters".
Switch parameters. See "Switch Parameters".
Timer parameters. See "Timer parameters".
Network File System (NFS) parameters. See "NFS Parameters".
Socket parameters. See "Socket Parameters".
Indy Video parameters. See "VINO Parameters".
Extended Accounting parameters. See "Extended Accounting Parameters".

Each section begins with a short description of the activities controlled by the parameters in that section, and each listed parameter has a description that may include:

Name - the name of the parameter.
Description - a description of the parameter, including the file in which the parameter is specified, and the formula, if applicable.
Value - the default setting and, if applicable, a range. Note that the value given for each parameter is usually appropriate for a single-user graphics workstation. Values may be presented in either hex or decimal notation.
When to Change - the conditions under which it is appropriate to change the parameter.
Notes - other pertinent information, such as error messages.

Note that the tunable parameters are subject to change with each release of the system.
