4.8 TSC Card Database

4.8 TSC Card Database
Each TSC card hosts a separate database; therefore, the protect card's database is available if the
database on the working TSC fails. After a database change, there might be a 30-second interval before
the TSC starts writing the data to the Flash drive. If you reset the active TSC immediately after a database
change, the change could be lost.
You can also store a backup version of the database on the workstation running CTC. This operation
should be part of a regular ONS 15600 maintenance program at approximately weekly intervals and
should also be completed when preparing an ONS 15600 for a software upgrade or a pending natural
disaster, such as a flood.
The Internet Inter-ORB Protocol (IIOP) port is not backed up and restored.
Note
The ONS 15600 does not allow you to restore a database from one node to another node. You can install
Note
a database from one node on another node by using the Configure Node option on the Maintenance >
Database tab.

4.9 Software Load Revert

Before you upgrade to Software Release 8.0, you must create a database backup. If you later need to
restore the original working software load from the protect software load, CTC displays a prompt
requesting the location of the backup. Any provisioning performed with Software R8.0 will be lost when
the Software R1.1.x backup is restored.
After a software load is activated (upgraded to a higher software release), any circuits created and
Note
provisioning performed will not reinstate if an older database is restored. The database configuration at
the time of activation is reinstated after a revert.
