Dump History
November 2009 95
Normally all history is collected in a single main history buffer
accessible as module 1 channel 1. During driver configuration, you
can choose a number of physical history buffers and application
history buffers. If these are non-zero, additional history buffers are
created, and appropriate items are logged in those buffers rather
than the main log.
Under almost all conditions, the history should be configured for 0
physical histories and 0 application histories, and the only
module/channel combination which should be dumped is module 1
and channel 1.
Dump History (dh) is supplied with the device driver and resides in
boston/driver//user on all systems.
The information provided by Dump History is very useful to Dialogic
Technical Services and Support in identifying and solving problems.
module 0
The most recent application corresponding
to channel as an ordinal unit.
module FE
The fixed application history corresponding
to channel as index.
