Enterprise Data Recovery

Announcing EDR–Enterprise Data Replicator™–The New Standard in Real-time Peer-to-Peer Replication


E-Net Enterprise Data Replicator sets the new standard in database application availability. EDR provides replication and propagation solutions designed specifically for real-world applications. High-value. High-volume. Critical systems which have the ultimate availability requirements. Not 99%. Not 99.99999%. Systems that require 100% uptime. If you have an application which absolutely must be available at all times, you should consider EDR.

EDR builds on E-Net’s twenty years of experience with mainframe database replication and offsite recovery solutions, for both continuous availability and disaster recovery applications.

EDR uses a completely new and redesigned software architecture exploiting today’s best practices in development and quality assurance. It provides the leanest and cleanest high-end data replication capability.

EDR addresses today’s and tomorrow’s demands for completely available and responsive mainframe database applications across potentially many nodes, distributed across the globe, separated by thousands of miles.

EDR goes well beyond the capabilities of any hardware mirroring approach, which are by design uni-directional. EDR does not require any proprietary hardware.

EDR fully exploits today’s and tomorrow’s network configurations and topologies, with full TCP/IP and Websphere MQ support.

EDR can be used in differing scenarios depending on business requirements:

Scenario A

Instantaneous switch-over to backup site. Replication is uni-directional at any given time. Backup locations can be used for query and other read-only workload, thus providing the ability to balance workloads across the network. Switch-over capabilities enable both scheduled and unscheduled outages to be efficiently and transparently handled with no loss of data.

Scenario B

Multiple live sites each handling update transactions. Loss of a given node, scheduled or unscheduled, is transparent to users. Provides the ultimate in load balancing capabilities — every site can handle both retrieval and update transactions when required. Applications are provided a wide range of options for handling conflict resolution, with advanced conflict detection algorithms.

EDR automatically recovers from unforeseen system outages, abends and operational errors with no impact on users. It is easily maintained and operated, enabling true 100% continuous operation — 24 by 7 by 365. Your applications are always up. Your information is available all day — every day.



Open Communications Environment Across Networks

EDR: OCEAN provides the infrastructure for advanced database replication. It uses TCP/IP or Websphere MQ capabilities to convey any kind of message across multiple nodes. Uses the most advanced and efficient techniques for communications, enabling customers to use EDR within existing and planned networks.

EDR: OCEAN dynamically detects and responds to changing network connections, automatically
balancing traffic across the available WAN facilities. When required, packets are routed over alternate connections when a network outage occurs.

The OCEAN layer provides command and control interfaces, enabling web browser or green-screen administration and operations. It is designed specifically for today’s requirements for fully automated, flexible and easy-to-use interfaces.


Open Architecture Replication

EDR: OAR/DB2 provides real-time DB2 for z/OS replication and change propagation. It uses sophisticated and highly efficient methods for change capture using a unique log capture approach. Data synchronization is handled automatically and completely without disruption using a patent-pending algorithm.

OAR/DB2 enables fully dynamic and automatic activation for new objects, plus the ability to tolerate DDL changes at a source site with no outage at target. It uses a specially-designed exploitation of static and dynamic SQL to apply changes at a target location with minimum overhead.

OAR/DB2 completely supports DB2 data sharing within the Parallel Sysplex, enabling true parallelism exploitation at both source and target sites.

OAR/DB2 has no requirement for unique indexes, and fully exploits and tolerates DB2 referential integrity, stored procedures and triggers. It handles LOBs. EDR enables your applications to use DB2 features and capabilities without restriction.

EDR - Real Time. Peer-to-Peer.
100% Availability.

EDR sets the standard for mission critical application availability. Advanced technology from E-Net Corporation, the leader in replication and recovery solutions. To purchase EDR—Enterprise Data Replicator with OCEAN and OAR technology or for further information, please contact us.



Information systems form the foundation of today’s healthy, growing businesses. And, as such, these systems must be ever ready to meet the simultaneous demands of customers, clients, employees and the Internet. Including telephone and on-line business, it is not uncommon for networks to process between 500 and 1,000 transactions per second. Downtime means lost customers.

E-NET2 is a highly cost-effective shadow database facility that permits a user to maintain a remote shadow IDMS database, working together with RRDF. E-NET2 can also be used on a stand-alone basis to maintain a local shadow database.

E-NET7 utilizes enhanced “Huffman” encoding techniques that perform a sophisticated bit-level compression tailored to the user’s data stream. Because of the “scrambled” nature of the encoded data, the results may, in addition, satisfy security requirements.
