Secure Systems Integrated Recovery

While no computer is totally immune to the potential for error, only a rich and robust operating system like OS 2200 provides automated recovery from errors.

All it takes to compromise data integrity on any system is a software, hardware or human failure. If the failure can’t be resolved, a business-critical database could be corrupted. And transactions could be lost.

Databases, Transactions and Messages

OS 2200 gives you recovery capabilities that are unequalled. That’s because database, transaction and message recovery are fully integrated. Any difficulties caused by a failure are minimized. Partially completed transactions and undelivered output messages from completed transactions are handled. The recovery process is expedited. And system availability is maintained.

Recovery is totally automatic – and takes only a few minutes! In contrast with other popular database environments, you don’t have to decide which items to manually recover and which ones to discard. What’s more, its automation reduces the possibility of (further) human error.

Three Data Models

OS 2200 offers you a choice of three popular data models: relational, network and indexed sequential. And all three can share the same database environment when it comes to commit, recovery and rollback. The superior integration of the Universal Data System environment means your applications can use any combination of these databases – without the complexity and overhead of two-phase commit – even in a multi-host shared database environment. This reduces the possibility of requiring manual intervention in order to resolve any differences between the databases when an error has occurred.

Just take a look at what OS 2200 Integrated Recovery software can do.

• Ensure consistency between database updates and message processing
• Synchronize (integrate) database recovery with transaction and message recovery
• Protect against the effects of hardware and software failures
• Participate in two-phase commit protocol with off-platform and on-platform databases

But wait… there’s more. When multiple hosts share databases, the OS 2200 Extended Processing Complex architecture allows another system to recover the work of a host that has experienced unplanned downtime.
