The market participants' connections and trading volumes during these sessions remained similar to any regular trading day on the primary site.
Regular trading has resumed from the primary site from today, BSE said in a statement. In order to provide business continuity across all its systems and operations, BSE actively maintains four sites —primary site, disaster recovery site, data backup site and emergency operations centre.
A disaster recovery site is a real time replication of the primary site and ensures that all data is available at disaster recovery site with near zero time lag. This enables BSE to switch-over to disaster recovery site at any time during the day, in case of any eventualities.
"BSE, along with ICCL (clearing corporation of BSE), has successfully conducted a two-day live trading session from its Disaster Recovery Site on July 4 and 5, " the stock exchange said. "All systems of BSE ran from its disaster recovery site, which is in a different seismic zone," it added.
According to BSE, the switch over to disaster recovery site and coming back to primary site "had been absolutely seamless with no impact to any of its systems and services. The market participant connections and trading volumes remained similar to any regular trading day on the primary site.”
The trading sessions were conducted in line with regulator Sebi's mandate to the bourses to conduct their operations from its disaster recovery site for two days. The trading operations was performed from its disaster recovery site itself, whereas the entire business operations were performed from its emergency operations centre.
Noting that the switch-over to disaster recovery site used to be a very time-consuming activity and involving a lot of manpower and co-ordination, which resulted in human errors, BSE said that to overcome the risks, the exchange has automated the entire switch-over and switch-back processes.
Among others, the automation tool provides a real-time monitoring of the sync status between primary and disaster recovery sites and has also helped reduce manpower requirement for handling operations from 100 to 10 people.
In a separate development, the BSE on Thursday said that investors with outstanding claims against Kassa Finvest, which was found to have misutilised client funds, can file an arbitration against the broker within 90 days and will be eligible for compensation thereafter.
