1.9 Database and Text File Management

1.9.1 Database Management
1.9.1.1 Introduction
All configuration and provisioning changes made by the system user are stored internally in the system configu-
ration database. The database is updated dynamically any time a configuration change is made to the system,
through the normal use of CLI commands. When the control module is restarted, it restores the system con-
figuration from the database.
The database is stored in the control module FLASH memory, but is not a user manageable file in the FLASH
system, so no file-related CLI commands apply to it. A separate set of CLI commands is provided to manipulate
the database.
For a system configured for duplex operation, a copy of the current database is located on both the active and
inactive control module. Configuration changes made on the active control module are automatically written to
the database and propagated to the copy of the database located on the inactive control module. As long as the
control modules are operating in synchronization, any action that results in configuration data being written to
the database is reflected on both control modules. When the inactive control module is being brought online
from an offline condition, its database is bulk synchronized with the active control module.
During a normal software release upgrade, commands that manage the configuration database are executed.
Summaries of the commands follow.
1.9.1.2 Database Backup
If required, the database containing the most recent provisioning and configuration data from the active CFC
would be used to restore the system back to normal.
Keep a copy of the most recent database on a secure network server by preforming a backup after any

configuration change.
During a normal software release upgrade, the database is manually backed up if a downgrade is required after
the new load files have been committed. If a downgrade is required, a database restoration is performed.
The steps in performing a database backup include:
Designate a network server for secure storage of the current configuration database

The user can specify the source of the database backup as either the RAM database contents or the
