Audio Playback

By default, VMM does not attempt to load all vocabulary elements into VDM. If

"loadall on" is specified in the vmm-mmf.cfg file, VMM attempts to load all

vocabulary items into VDM. Elements not loaded into audio memory will be cached

in/out of memory as necessary.

Proper setting of vdmmaxlock is important to insure there is enough VDM reserved

for caching. If the size of the activated MMF elements exceeds available voice

memory (VDM becomes depleted), an alarm is generated. If some of the VDM is

freed by deactivating one or more MMF files, the MMF files to be loaded must be

deactivated and then reactivated in order to use newly available memory. The

following parameters directly affect VDM performance. pagesize, vdmmaxlock,

and preload are set in the vmm.cfg file (see The vmm.cfg File on page 144).

loadall is set in the vmm-mmf.cfg file (see The vmm-mmf.cfg File on page

146). If changes are made to these entries, VMM must be stopped and then restarted

for the changes to take affect. For information on stopping and starting VMM, see the

Avaya Media Processing Server Series System Operator’s Guide.

Configuration Parameters for Voice Data Memory Management

VMM Parameter Description

pagesize The size, in kilobytes, to use for a single segment of VDM. A value

that is too large means that more memory is taken from VDM.

Decreasing the value makes more efficient use of VDM (less wasted

space) but uses more system memory. The default value is 8 Kb.

Typically, the defaults should be used. Changes to this parameter

should be considered in the context of the value of vdmmaxlock

(see below).

vdmmaxlock Specifies the maximum amount of VDM, as a percentage, to use for

locking elements. This option is used to ensure there is sufficient

VDM available for the VMM caching mechanism to function

efficiently. Unless good reason exists otherwise, the default value of

50% should be used. Increasing this value makes audio element

access quicker, but reduces VDM available for caching audio data

not locked in VDM; decreasing this value has the opposite affect.

Changes to this parameter should be considered in the context of

the value of pagesize (see above).

preload Specifies the number of seconds of audio to load into VDM prior to

an element’s initial usage. This option is used in conjunction with

loadall (see below). If loadall is turned on, VMM attempts to

preload audio data for each element: if off, VMM makes the attempt

only for locked elements (see “Custom Loading” on page 171 for

more information). If set in the vmm-mmf.cfg file, should precede

any mmfload commands. Default value is all (audio data loaded

into VDM).
