Customer Success Story

The Jackson Clinic

• Established in 1950 by a group of 5

medical and surgical specialists.

• The first multi-specialty group practice

in Tennessee

• Currently one of the largest group


• Currently one of the largest group

practices in the country.

– 7 locations spread through out the West

Tennessee

– 150+ physicians

Business Pain and Technology Issues

• Misys Healthcare's EMR

– Completely paperless Electronic Medical Record (EMR) system

– AIX/Informix based solution

• Disaster recovery requirements

– Near zero recovery point and recovery time objectives

– Protection from both system and site failures

• Hole in initial deployment


• Hole in initial deployment

– P-Series and DS4800 SANs were deployed in each data center

– Basic replication done between the SANs

– Software level errors were replicated to our failover site which left us with two unusable systems.

• Extended requirements

– Replicate our data to our secondary data center.

– Recovery from data integrity issues.

Why Vision?

• We brought our extended requirements to our IBM business partner, Mainline Information Systems, who recommended the Double Take RecoverNow solution.

• Double Take RecoverNow handles all data replication for our application. As soon as any change is made to any volume group that we are protecting, Double Take RecoverNow captures and then copies that data to our secondary system giving us a true up-to-the-minute replica of our production system.


replica of our production system.

• On the failover system, Double Take RecoverNow keeps track of all the changes that it has made over a particular length of time. Through this tracking mechanism we can now choose to activate our secondary system and mount up an exact working replica of production environment from a specific point in time.

Success Story

• Appointment secretaries accidentally deleted all future appointments for a group of doctors. – Thousands of appointments were deleted.

– We used Double Take RecoverNow to dial back and mount up a clone of the database to a point in time just before the data was deleted.

– We extracted the missing data from the clone and imported it back into the production system without experiencing downtime

– The effected physicians never knew anything even happened

• Physicians work 24x7– We use the clone to perform a full database backup


– We use the clone to perform a full database backup

– Zero production down-time for backups

• Misys upgrade verification– A true test of the upgrade using production data

– The upgrade to production is done with confidence

• Application troubleshooting– Application problems are investigated in the clone

– Misys can troubleshoot and test fixes for application problems without affecting production
