PT Bank Central Asia Tbk (BCA), the largest commercial bank in Indonesia, is keenly aware of how much its customers rely on online and mobile banking to check account balances, make purchases, transfer funds, and engage in other banking activities. Two years ago, the IT staff determined that offline reorganization of the IMS databases underlying online banking systems resulted in too much downtime for digital banking. Deeming that even a few minutes of downtime was unacceptable, IT decided to replace its offline reorg process with an online one. When staff members conducted the proof of concept (POC), their primary selection criteria was the ability to deliver near-zero downtime.
After extensive testing of multiple solutions, HALDB and Full-Function Database Solutions (now called BMC AMI Full Function for IMS) was selected. It was the clear leader in a proof of concept test, enabling BCA to reorg to a copy of IMS databases, while capturing all updates that occurred during the reorg. BMC performed the online, concurrent reorg with near-zero downtime. After the reorg, the solution applied updates, swapped dataset names, and put the reorganized database online.
BCA customers rely more on mobile and online services than on branches and ATMs, which makes the shortest possible downtime a business imperative.
