Assure MIMIX HA helped OCBC Bank reduce downtime and improve response to customers

With more than one million electronic transactions processed every day, OCBC Bank must be able to ensure that its IT systems are protected against both downtime and data loss. Any interruptions to service would have immediate and serious repercussions, damaging the excellent reputation OCBC Bank has forged over the decades.

As part of its mission to become a world-class financial institution in the Asia-Pacific region, the Singaporean-owned OCBC Bank instituted a dynamic three-year IT strategy known as OCBC 3.0. One of the priorities of the plan was to implement a world-class high availability solution to keep its network operating around the clock.

Previously, when the system came down for whatever reason, the IT staff had to send backup tapes to the Disaster Recovery Center outside of town, where the data was restored on backup machines. This process required that staff at the bank branches re-key all the transactions for the day or, more specifically, all
transactions entered since the last backup.

If the system came down near the end of the day, the recovery period would take longer as nearly an entire day’s worth of transactions would have to be re-keyed after the latest backup data was restored from tape at the Disaster Recovery Center.  Actual experience showed that it typically took about eight
hours to restore the data for all applications, according to David Hah, OCBC Bank Malaysia’s Assistant Vice President of Information Technology.

To begin the project, OCBC Bank Malaysia rigorously evaluated the offerings of various high availability vendors. IBM Malaysia proposed Precisely’s Assure MIMIX HA solution to provide high availability and continuous operations running on the IBM System i servers. After reviewing all the options, the innovative
features and superior architecture of Assure MIMIX HA tipped the scales in Precisely’s favor.

“Assure MIMIX HA is stable and easy to configure and mange.  It is very user friendly,” says Destine Lim, Head of IT for OCBC Bank Malaysia. “In addition, Assure MIMIX HA allows for intrasystem replication within the same computer.”

OCBC Bank Malaysia’s core banking applications, such as retail banking, credit card, treasury and credit leasing reside on its production server at its main branch in Kuala Lumpur, the Malaysian capital.
