Introduction
This chapter describes how to recover your database in a disaster situation, how to recover your database
from another database, and how to recover data from the Call Agent shared memory.
Cisco recommends backing up all data on the Element Management System (EMS), Call Agent (CA)
and Feature Server (FS) platforms on a daily basis, and saving the backed up data to a remote server.
Data backup files are needed in the unlikely event that data on both the primary and secondary sides of
any platform become corrupted. In that case, data must be restored from a backup file.
Restarting a Cisco BTS 10200 Softswitch Process
When a BTS 10200 process exits due to an internal error (such as SIGSEGV on UNIX) or is terminated
by the platform, the system automatically restarts the process that shut down.
Restarting the process is a preferred alternative to switching over to the mate, because the restart
preserves stable calls and also attempts to preserve transient calls. When a process is restarted, the
process audits information such as resource states and attempts to repair inconsistencies. If a process
experiences a high failure rate (even after repeated restarts), the system will switch over to the mate.
Disaster Recovery From Flash Archive
This section describes the steps needed to restore the Flash Archive on the BTS 10200 system. The flash
archive backup is performed before any software upgrade or for maintenance routine purpose. This
procedure is used ONLY when both mirrored disks are corrupted or cannot be booted.
Flash Archive is a Sun Solaris tool that allows you to take an image of a host and store it on a network
file server (NFS) that can be used later for disaster recovery.
For the BTS 10200, it is recommended to take a system flash archive whenever the Solaris Operation
System is being modified.
