Tcc2 Card Database; Software Revert - Cisco ONS 15454 DWDM Installation And Operation Manual

Chapter 17 Cisco Transport Controller Operation

17.7 TCC2 Card Database

When dual TCC2 cards are installed in the ONS 15454, each TCC2 card hosts a separate database;
therefore, the protect card database is available if the database on the working TCC2 fails. You can also
store a backup version of the database on the workstation running CTC. This operation should be part
of a regular ONS 15454 maintenance program at approximately weekly intervals, and should also be
completed when preparing an ONS 15454 for a pending natural disaster, such as a flood or fire.
Note The following parameters are not backed up and restored: node name, IP address, mask and gateway,
and Internet Inter-ORB Protocol (IIOP) port. If you change the node name and then restore a backed up
database with a different node name, the circuits map to the new node name. Cisco recommends keeping
a record of the old and new node names.

17.8 Software Revert

When you click the Activate button after a software upgrade, the TCC2 copies the current working
database and saves it in a reserved location in the TCC2 flash memory. If you later need to revert to the
original working software load from the protect software load, the saved database installs automatically.
You do not need to restore the database manually or recreate circuits.
The revert feature is useful if a maintenance window closes while you are upgrading CTC software. You
can revert to the protect software load without losing traffic. During the next maintenance window,
complete the upgrade and activate the new software load.
Circuits created or provisioning done after a software load is activated (upgraded to a higher release) do
not reinstate with a revert (for example, 4.0 to 3.4). The database configuration at the time of activation
is reinstated after a revert. This does not apply to maintenance reverts (for example, 2.2.2 to 2.2.1),
because maintenance releases use the same database.
