EDR Enterprise Data Replicator

E- Nets Enterprise Data Replicator sets the new standard in databaseapplication availability. EDR provides replication and propagationsolutions designed specifically for real-world applications.

Your applications: High-value. High-volume. Critical systems whichhave the ultimate availability requirements. Not 99%. Not99.99999%...... Systems that r equi re 100% uptime .

EDR provides industrial-strength real-time peer-to-peer replication youcan deploy with confidence.

EDR replaces RRDF /L ogApply for D B2 for z/OS Version 8 andbeyond

EDR: Solutions

EXPERIENCE EDR builds on E- Nets twenty years of experience with mainframe database

replication and offsite recovery solutions, for both continuous availability anddisaster recovery applications.

LEAN AND CLEAN ARCHITECTURE EDR uses a completely new and redesigned software architecture exploiting todays

best practices in development and quality assurance. It provides the leanest andcleanest high-end data replication capability.

EXTENDED DISTANCE EDR addresses todays and tomorrows demands for completely available and

responsive mainframe database applications across potentially many nodes,distributed across the globe, separated by thousands of miles.

EDR: Solutions

GOES BEYOND MIRRORING EDR goes well beyond the capabilities of any hardware mirroring approach,

which are by design uni-directional . EDR does not require any proprietary

hardware. NETWORK COMPATABILITY EDR fully exploits todays and tomorrows network configurations and

topologies, with full TCP/IP and Websphere MQ support. BULLET-PROOF

EDR automatically recovers from unforeseen system outages, abends andoperational errors with no impact on users.

EASE OF OPERATION EDR is easily maintained and operated, enabling true 100% continuous operation

24 by 7 by 365. Your applications are always up. Your information is availableall day every day.

Business Requirements

Scenario B Peer-to-Peer Replication Multiple sites simultaneously handling update workload Virtual Data Center concept Enables unrestricted load balancing across multiple sites

A given user may be normally assigned to his/her preferredsite but can be immediately redirected to an alternate sitewhen preferred site is not available

Need to resolve logical collisions which are possible due toinvolvement by multiple commit managers

All sites have Referential Integrity, Triggers, StoredProcedures

Enterprise Data Replicator - Goals

Reliability The cornerstone to E-Net's ongoing success is reliability - guaranteed

data movement from DB2 to DB2 without compromising data integrityor the operating system environment. In the world of continuousavailability, the ability to recover from abends or unforeseen systemoutages must have no impact on the users of the system.

Performance As the performance leanness of the E -Net Log Apply engine has

always been acknowledged by our customers, it is a key goal for EDR.E-Net designed and implemented EDR based on years of experiencehandling real-world applications having both high transaction rates andlarge databases.


19/34

Flexibility EDRs engine is structured and flexible enough to take advantages of

any new or improved features for any DB2 version. An example would be the ability to adapt to a new DB2 data type.

Maintainability EDR is easily maintained and by design anticipates true continuous

operations (24 by 7). EDRs engine is able to switch between softwarelevels without impacting current users of the system. In addition EDRis software back level tolerant. This means that it permits differentversions of the engine to execute concurrently with no impact to users.The engine itself contains easily distributable and maintainablemodules implemented and architected by design.

Compatibility Compatibility with the existing versions, and future versions of DB2

and other DBMS products are a must. Downward compatibility between and among versions of EDR is also supported.
