Communication Infrastructure – KEPCO

KEPCO switched from Oracle to Altibase for better performance, lower TCO and superior support.

Use Case: Communication Infrastructure

Current Customers: KEPCO

Industry: Manufacturing


KEPCO is South Korea’s largest electricity producer.


KEPCO’s Communication Infrastructure (CI) system monitors and supervises its optical fiber infrastructure. Its legacy Oracle DBMS posed various problems due to its slow performance, high TCO and inadequate support.

  • Oracle’s 200 TPS fell short of the required 300 TPS.
  • KEPCO was unhappy with Oracle’s license price.
  • Oracle’s maintenance price was also unbearably expensive.
  • Given the nature of the CI systems, real time reaction to incidents is of the utmost importance. However, Oracle’s support was often not prompt or readily available when it was needed most.


KEPCO has deployed Altibase since 2009. Altibase’s hybrid architecture has provided KEPCO precisely with what it needed: the speed that is required of an in-memory database and the vast storage of historical data that is required of an on-disk database. Altibase delivered 2.5 times faster speed than Oracle, and KEPCO did not need to purchase separate on-disk databases for the purpose of storing vast amounts of data.


  • Altibase provided 500 TPS, well above KEPCO’s requirements.
  • KEPCO liked Altibase’s competitive license and maintenance prices.
  • The switch from Oracle to Altibase resulted in 75% reduction in TCO.
  • KEPCO has been happy with Altibase’s stellar support.
  • KEPCO subsequently adopted Altibase in 2011 and the following years for other systems
