Unanswered: one database vs. 3 databases in 1 unix box
Please give me some good ideas on this ....
I have 3 databases in one unix box. ( Sun Sparc Solaris2.6 and RDBMS is oracle8). I have 1 GB of memory and 36 GB of harddisk and 4 cpu. Currently,
those 3 databases consists of the following applications: 1 - for Production Support, 1 - for Human Resources and 1 - for Services.
We decided to create separate database for each application because they have no relationships.
I want to clarify what are the prons and cons if i'm going to create one database which consists of that 3 applications then control will be on schema only.
What are the effects of having one database in one unix box or having 3 databases in one unix box?
