Having separate databases gives you some flexibility. You can manage them
separatly, for instance you can upgrade the database to a newer version in
phase. Also, if you lose a database only one customer is affected. Do all
the customers always use the same application (same version)? If one
customer wants to use the latest version of the application (perhaps for a
feature they have long been waiting for) when it become available and
requires the latest version of Oracle and the rest of the customers want to
stick with the old version, then you have to put them into separate
databases.
On the other hand, separate databases means more database to manage.
So the answer is depends on your situtaion.
