Credit Card Application Availability to Survive Disasters


The largest U.S. processor of credit card transactions provides card management services for its customers on HPE NonStop systems.


The original configuration was vulnerable to failure and needed an easy to implement and reliable disaster recovery solution. The customer required flexibility in the database mappings to allow for differing file/table partitioning layouts between the source and target systems.


  • Use HPE Shadowbase active/passive business continuity to provide uni-directional disaster recovery capability
Diagram of a credit card application posting its transactions to an active NonStop database, with Shadowbase uni-directional replication sending the transaction changes from the active database to the passive database. If the active NonStop fails for some reason, users are connected to the passive database by the credit card company's IT team.
