Sybase Mirror Activator with EMC Symmetrix Remote Data Facility
A Technical Reference for using Sybase Mirror Activator (MA) and EMC Symmetrix Remote Data Facility (SRDF/S) in a Unix Enviroment
Sybase Mirror Activator is a business continuity solution that dramatically lowers overall TCO by cutting failover time, provides zero data loss, reduces network bandwidth requirements and makes the usually idle standby database available for reporting and decision support. EMC Symmetrix® Remote Data Facility (SRDF®/S) software provides a mirrored data storage solution whose purpose is to maintain multiple, real-time copies of logical volume data in more than one location.
You can find more information about EMC and their products at http://www.emc.com. The solution described by this paper, Sybase Mirror Activator with EMC Symmetrix Remote Data Facility, combines the two technologies to provide both guaranteed data delivery while providing improved ROI from continued access to standby resources. The remote replication technologies of EMC are used to create initial copies of the database and to create a mirror copy of the database transaction log. Sybase technology is then used to read the log mirror and update the available standby systems without impeding their availability. As well as an overview and detailed description of the products and solution, this paper provides step-by-step examples for using the combined technologies in disaster recovery situations.
