553-3001-365 Standard 4.00 August 2005
Additional CLI commands have been added enabling any task to be marked
as critical or non-critical, regardless of its default designation. This could be
used, for example, to mark a “misbehaving” task as non-critical to avoid a
card reset. This would enable the problem to be debugged.
The maintenance audit is available only for the IP Line 4.5 application
running on the ITG-P 24-port and Media Card line cards. It is not available
on the Signaling Server as it does not have the exception handler, stack dump,
and syslog file functions of the other cards.
Critical task list
All application tasks default to the critical task list. These applications
include: TPS, VTM, SET, VTILIB, UMS, UMC, RDP, VGW, RTP, RTCP,
ELC, baseMMintTask, and A07.
The following VxWorks system tasks are also on the critical task list: tShell,
tNetTask, tExcTask, and tTelnetd.
All other tasks are on the non-critical task list. The monitor task is called
tMonTask.
Any data entered at the CLI that deviates the operation from the default is
saved in the /C:/CONFIG/AUDIT.INI text file. The contents of the file are
loaded as the application boots up and provides the required non-volatile
storage for entered settings. It is applicable only to the card on which it
resides. It can be manually copied from one card to all other cards in the node
if desired.
History file
A history file is created when the card starts. The text file is called audit.his
and it is stored in the /C:/LOG directory. This file contains a list of the
problems found and the actions taken by the maintenance audit. The audit.his
file has a fixed size of 4096 bytes.
The most recent records in the file overwrite the oldest records with newer
events appear at the beginning of the file. A record in the file is a one-line
string with maximum size of 256 characters.
