Hi Martin,
Sorry for not telling the DBMS upfront ...
It is Oracle 11.2g.
Hmm... after dropping the source client, in order to 'resize' the datafiles... we can use BRTOOLS to do so but it might need to require drop all the objects that belongs to the datafiles / tablespace...( not sure how can archieve it ... wonder if will leads to any inconsistencies ... ? )
By the way, if right after deleting the source client (currently my Oracle DB has plenty of freespace) and I perform System Copy (Migration) from PRD1 to PRD2.
Will System Copy only export the used spaces or it will export also the freespace and it will require the target ssytem to have the same Total Size (Used + Free spaces) as the source system ?
Thanks.
Best Regards,
Ken
