Crash Recovery |
|
Data loss situations are common in all computers due to corruption, user errors, virus infections, or system failures. All result in loss of critical data. Crash recovery is the ability to restore a system without having to restart it.
In Cordys, if a business process encounters a sudden problem due to system or processor failure, the same can be restored using the crash recovery feature during runtime.
Need for Crash Recovery
Consider this example wherein a business process is scheduled to run 400 iterations, but the SOAP processor crashes after 200 iterations. In such a case, if the SOAP processor is restarted, the entire process has to begin again (i.e., from the first iteration). However, if crash recovery is enabled, the business process restarts from the point at which the process was terminated (in this case, from iteration 201).
