SAND Searchable Archive   REVIEWER: Young-Mun Cho, e-banking division manager for National Agricultural Cooperation Federation (NACF), South Korea.BACKGROUND: A national financial services institution established in 1961, NACF currently has more than 4,000 branches throughout South Korea. It operates the largest electronic network system in the country, offering telebanking, e-banking, mobile/PDA banking and a variety of automated services.

PLATFORMS: IBM p670 server with dual 1.1 GHz CPUs and GB of RAM; IBM AIX 5.2.   PROBLEM SOLVED: NACF processes a very large volume of e-banking transactions daily, and this is increasing steadily as our customers become more comfortable with Internet banking. Currently, these transactions produce at least 12GB of log data per day, and as much as twice that at month's end. All this data must be kept available for two months so that call center staff can access it if necessary to respond to customer support requests. Previously, when older data was needed, the relevant data set had to be restored from a backup cartridge into the source system, where a simple text search was used to locate the desired information. This was an unacceptably labor-intensive and time-consuming process that normally took two to three days. However, it was not practical to keep such large amounts of historical data available in our main data warehouse system: not only would it require a very large amount of disk space and negatively affect warehouse performance, but the loading and indexing times involved would be prohibitively long. A solution based on SAND Searchable Archive is currently used to store two months of transaction log data - nearly a terabyte - in a very compact (approximately 50GB) archive that can be directly searched via a simple application using standard SQL. Results are now returned in minutes rather than days. The archive process is fully automated and accommodates changes to archived objects (i.e., addition or removal of fields in the logs) over time with minimal administrative effort.
