As more and more installations are implementing or thinking about multi site sysplexenvironments for availability and disaster recovery it is important to understandthe performance implications to your IMS transactions and databases. IBM performedsome benchmarking of IMS and other subsystems at various distances to betterunderstand these implications and this information will be used to demonstrate theimpact and ways it might be minimized.
