Hello
I am not sure I understand your statements. I'll try to answer the way I understand them
- snapshots are not one time. Each incremental synchronization in a conversion job creates a separate VSS snapshot;
- I haven't worked with Oracle but I have worked with MS SQL Server and Informix Dynamic Server. The databases' data reside either on a raw device or in a single file per DB (disregarding logs). The SQL server is one or more services that write to the databases. Whenever stopped gracefully, it keeps the databases in consistent state (I have heard that what I call 'database' is called 'schema' in Oracle and their 'database' is the whole set of 'databases'; however that doesn't invalidate the case of consistency).
- as conclusion - there is no trouble to P2V machines with SQL servers from a consistency point of view, as long as the correct procedure is followed.
HTH,
