Figure 73: Avaya Communication Manager’s recovery levels
Restarts
These automatic recovery levels are listed from mildest to strongest, which is also from quickest
to slowest and more frequent to less frequent:
●
Single process restarts
●
System warm restarts
●
System cold restarts
●
Communication Manager reloads
●
Linux operating system reboots on S8300/S8700 Media Servers
Single process restarts
Process sanity audits are performed routinely (approximately every 10 seconds) on many
dozens of key software processes. In the event of a process hang, that single process will be
restarted, and no call outage will result. If three single process restarts are needed within a
60-second probationary period, the third single process restart is deemed ineffective, and will
instead escalate to a system warm restart.
System warm restarts
This mechanism preserves all stable and held calls, as well as feature activity data, throughout
the brief recovery period. Processes are essentially started with the same data and stacks that
they were using prior to the warm restart. If three warm restarts are needed within a 15-minute
probationary period, the system warm restart is deemed ineffective, and will instead escalate to
a system cold restart.
