The latest business continuity news from around the world

BSE stock exchange conducts two-day live business continuity exercise

BSE, the Mumbai-based stock exchange, and its clearing corporation, ICCL, have successfully completed a two-day live trading session from the BSE disaster recovery site.

During the exercise, which took place on 4th and 5th July, all BSE systems ran from its disaster recovery site which is in a different seismic zone to the operational systems. In addition, trading operations were also performed from the disaster recovery site and business operations were performed from BSE’s emergency operations centre.  

BSE says that the switch over to the disaster recovery site and the return to the primary site have ‘been absolutely seamless’ with no impact to any systems or services. The market participant connections and trading volumes remained similar to any regular trading day on the primary site.

In order to provide business continuity across all its systems and operations, BSE actively maintains four sites: its primary site, a disaster recovery site, a data backup site and an emergency operations centre. A real time replication between the primary site and disaster recovery site ensures that all data is available at the disaster recovery site with near-zero time lag.

BSE has over 60 systems, applications and services at its primary site, an exact copy of which is also maintained at the disaster recovery site. The switch-over to the disaster recovery site used to be a very time consuming activity and involving a lot of manpower and co-ordination. The scale of complexities and inter-dependencies between these application was very high, which was prone to human errors. To overcome this, BSE automated the entire switch-over and switch-back processes. The automation now manages the switch of all 60+ applications. It also takes care of all interdependencies (database links, file interchange mechanisms, messaging etc) and ensures a smooth transition. The automation tool also provides real-time monitoring of the sync status between the primary and disaster recovery sites. Automation has also helped reduce manpower requirement for handling operations from 100 to 10 people.
