umm....well... I talked tooo much.
I have some presumptions about this oracle support systems.
Please scold me if i am wrong on these.
1) "Licenced" version can be registered through oracle.com.
2) metalink registration can be done using the registration number from above.
3) oracle support services contract means purchasing Oracle "man-hours" where oracle support services people will "physically" visit the client site and act as a consultant and it has nothing to do with metalink.
how about that.......
