BACKCHATTM

Fault Tolerance

• BACKCHAT can mirror one or more Image databases into one or more other databases in real time.
• The secondary data bases are continuously updated and are never more than a few seconds behind the primary ones, so if your primary system fails, you can switch over to a back-up system quickly.

Data Consistency

• BACKCHAT automatically ensures that the data is always syncronized.
• BACKCHAT will automatically recover affected data bases to the correct logical state when the network is restored after an interruption.

Improved Performance

• You can off-load enquiry and reporting functions to a copy of the primary data base.
• The copy can be on the same HP3000 or, as is more common, on a different HP3000.

Distributed DataBases

• BACKCHAT will maintain a physically distributed database that spans more than one HP3000.
• Update access can be provided to multiple copies of the same datasets concurrently.
• You can duplicate only a logical subset or the datasets.

24-Hour Availability

• BACKCHAT allows you to use the duplicate databases for backup leaving the primary ones available for access.

Complex Networks

• Consolidation into a central database can be done automatically.
• BACKCHAT permits concurrent updating to the same datasets on multiple HP3000's.

Application Transparent

• BACKCHAT can be implemented without changing the applications.
• Distributed database systems can be designed more simply.

Management Tools

• BACKCHAT can be completely controlled from a single HP3000.
• Reporting and status enquiries provide information that refelects the activity within the environment.
