- a new high-performance system which responds to the accelerated e-finance is required
- to improve the functionality of the disaster recovery system that was being used, introducing a new system and establishing a 24*365 service system were required.

Ark for Oracle

- configured 1:5 data replication between heterogeneous DBs and real-time data replication environments between accounting systems
- maintains maximum efficiency of its system through rapid technical support and regular system checks from ArkData

-Old administratino system could not handle the servers' load during the registrations.

Ark for Oracle

- With the existing old equipment, cost-effectively built a DB replication
- Improve performance by reducing the load on the system

- A new operating system needs to be built due to the low performance of the old server
- Necessity of DR System due to mandatory requirements by financial authorities.

Ark for Oracle

- Use Ark for Oracle to build disaster recovery systems to improve the reliability of system operations
- Replace aging server equipment by introducing Oracle ODA as a new system
- More than 3x performance improvement and successfully implement a cost-effective system

Necessity of DR system to protect data of student information which updates in real-time

Ark for Oracle, Ark for FR

- Establish a data center environment for stable academic data management
- Reduce the recovery time object (RTO) by replicating only the changed file events in real-time using Ark for FR

- Only had the storage duplication for the main center which left other WEB, WAS, AP servers, and the single Oracle DB without DR protection.

Ark for Oracle, Ark for FR

- Used Ark for FR to replicate files in WEB, WAS, AP server, and used Ark for Oracle for DB replication.
- Construct a DR system without any additional line installation by utilizing existing infrastructure.
