Number of Sequences in RAC database

Hi,

We have an in house OLTP application (2 node RAC on 10.2.0.4 Linux X64)  that for some reason was initially designed and developed to use table level sequences instead of oracle sequences
Now we are migrating / changing those over to use oracle sequences. Currently, there are 40 or so table that use sequences
Our question is that when it comes to using Oracle sequences, is there a downside of using higher number of sequences  (from performance,manageability and best practice perspective)?

For example, in our case, what would be the down side of creating 40 different Sequences to handle those 40 tables as opposed to creating 2 to 4 sequences to handle those 40 tables?

Howdy, Stranger!
