Restore the Informix Database
This section contains information that guides you through the process of restoring
the Informix database.
Prevent the Loss of Data
When you restore the database, you restore it with data that was present in the
database at the time of the backup. Unless you coordinate the restore procedures
with your billing vendor, you run the risk of losing data that was transmitted to
your system since the time of the backup. By adhering to the following guidelines,
you can minimize the risk that you will lose data when you restore the database.
Follow these guidelines when restoring the database:
Follow these guidelines when restoring the database:
Before restoring the database, contact your billing vendor and request that the
billing vendor send no more transactions until the restoration is complete.
If your system is still functional at the time of the restore, request that the billing
vendor download from the DNCS the latest set of IPPV billing transactions
before you start the restoration process. This way, you have the most current
record of subscriber IPPV purchases.
After completing the restoration of the database, contact the billing vendor and
request that the billing vendor re-transmit all transactions since the date of the
backup tape you used. For example, have the billing vendor re-transmit
transactions relating to DHCT service levels, PPV event definitions, and package
authorizations.

The script that restores the databases is called restoreDatabase. You can run the
restoreDatabase script with the following options:
-l — Local-tape-drive. Specifies tape drive to use on local host.
(for example — /dev/rmt/0h)
-r — Remote-tape-drive. Specifies tape drive on a remote host.
(for example — sparky: /dev/rmt/0h or 192.168.1.10: /dev/rmt/0h)
-c — check-database. Checks the integrity of the databases. (Does not fix if errors
are found.)
-v — verbose. Verbose output.
