In addition to comparing configuration snapshots, VCDA allows you to restore selected groups of configuration parameters from a saved snapshot. The only parameters that VCDA does not restore are the values of II_SYSTEM, the hostname and username.

You restore parameters by first selecting the snapshot file that contains the desired parameters. You can specify the specific parameters you want to restore. If the snapshot file you choose corresponds to a networked installation, you can also specify the value of the corresponding Ingres variables and the content of the relevant additional config.dat file, with an option to create the tree structure if it does not exist.

VCDA automatically creates a backup snapshot file of the current configuration before it restores parameters. If for some reason you do not want to keep the restored parameters, you can select this backup snapshot file to restore the parameters to their previous state.
