Re: Oracle Notificacion Server and DCM ports in OracleAS 10gR2

I am not sure how licensing works. If you have OID and SSO in different servers do you have to pay twice License?

These Blades have 2 CPU with HT, I think Oracle charge this as 1.5 CPU (or that is with Dual Core?)

And yeay it is 636 not 838, typo.
