o After we create the virtual copy using Delphix, can we insert data into that virtual copy? There is a requirement for generating synthetic data. So if we create synthetic data using some custom tools, can we insert that into the virtual copy?
o Is there a restriction on how much additional volume of data can be inserted into the virtual copy?
o Also, how much space will it occupy for the additional data?
Yes you can insert data into a VDB - you can treat the VDB just like any 'normal' database. However if you refresh the VDB than that data will be lost and will need to be reloaded.
The space used depends on how much data you install. It will be no more than if this was a traditional database and could be less due to the way Delphix stores data.
