Appendix A
Tuning the DECwindows System

This appendix lists the recommended values for quotas and system parameters for DECwindows Motif systems.

A.1 Establishing UAF Parameters for DECwindows Applications

DECwindows applications can be sensitive to user authorization file (UAF) limits. If problems occur while starting a session or while starting applications, or if an application disappears without an error message, check the UAF limits of the account under which the session was started.

Table A-1 describes suggested UAF limits. The specific numbers given are intended only as guidelines. The correct UAF parameters depend on your applications and processes. For more information see the OpenVMS System Manager's Manual.

**Table A-1 Recommended Settings for UAF Limits**
Limit	VAX Setting	AXP Setting	Usage
ASTLM	100	100	Asynchronous system trap (AST) queue limit
BIOLM	100	100	Buffered I/O count limit
BYTLM	40000	100000	I/O byte limit
DIOLM	100	100	Direct I/O count limit
ENQLM	200	300	Enqueue lock limit
FILLM	100	100	Open file limit
MAXDETACH	0	0	Maximum detached processes for a single user name (0 = no limit)
MAXJOBS	0	0	Maximum active processes for a single user name (0 = no limit)
MAXACCTJOB	0	0	Maximum active processes for a single account (0 = no limit)
PGFLQUOTA	32768	32768	Paging file limit
PRCLM	8	10	Subprocess creation limit
WSDEFAULT	512	1024	Default working set size
WSEXTENT	2048	8192	Working set extent
WSQUOTA	1024	2048	Working set quota

A.2 Establishing System Parameters for DECwindows Applications and Display Server

Because most DECwindows processes, especially DECterm windows, run as detached processes, you need to increase certain system parameters.

Table A-2 lists these parameters, their minimum settings, add values, and usage for VAX systems. Table A-3 lists these parameters, their minimum settings, add values, and usage for AXP systems. An add value is the increment by which the system increases a parameter until it reaches the minimum amount.

See the OpenVMS System Management Utilities Reference Manual for information about modifying system parameters.

**Table A-2 Recommended Settings for System Parameters on VAX Systems**

Appendix B
DECwindows Motif Keymap Names

Table B-1 lists the DECwindows Motif keymap names. The table is arranged based on the language for which each keyboard is designed. Choose the keymap ending in _DP for the data processing keyboard layout and the keymap ending in _TW for the typewriter layout.

For information about changing the default keyboard layout, see Section 3.3.5.
