Comparing Configurations with Visual Configuration Differences Analyzer
The Visual Configuration Differences Analyzer (VCDA) allows you to compare the configurations for a Ingres local installation by taking “snapshots” of its configuration. For example, after you install Ingres and have set up the database schemas, take a snapshot of the configuration. If you encounter problems later on, take another snapshot of the configuration and compare it to the earlier snapshot to see if any configuration changes have contributed to the problem. Keep an on-going record of configuration changes by starting with a snapshot of a new installation that shows all system defaults, and taking a snapshot of the installation each time the configuration is changed.
Note: VCDA compares the configurations of installations, but not the database object definitions within these installations. For instructions on how to compare database objects, see the Visual Database Objects Differences Analyzer (VDDA) help and the Database Administrator Guide.
Specifically, VCDA allows you to:
• Save a snapshot of the current configuration into a file
• Compare two saved snapshot files, or the current installation with a saved snapshot
• Restore selective groups of configuration parameters from a saved snapshot
For specific instructions on performing these tasks, refer to the VCDA online help.
