I want to secure my AS/400-data by setting up another AS/400 to be a complete mirror - "ready to go" - in the case where my production system is taken out for service or by accident. Therefore I would like to hear your experiences with one of these three products for High Availability: Vision, Mimix and/or DataMirror. How are the product, how are their support, what's good and what's bad ... Some of my concerns is the ability to deal with OV/400-documents realtime and performance with S/36-files in QS36F. Any input is appreciated. TIA, Soeren soeren_moerch@dansommer.dk
