db2 “rollforward database ts1 to 2000-06-19-19.56.00.0000 and stop”

12.Start the SAP system TS1 on the Primary server by logging on as user ts1adm

and issuing the following command:

startsap

Summary

DB2 UDB’s Suspend I/O technology provides a very powerful mechanism to offload work on to a secondary system, as well as providing a means to plan for disaster recovery. This functionality along with the utilization of the IBM Enterprise Storage Server provides an ideal environment for running an SAP R/3 system.
