In the good old days of 8.0, this was a problem for advanced replication :
the table you wanted to replicate had to have a PK and it had to be
enforced by a unique index (the error message we got when this was not the
case was "table or view does not exist" : very helpful in tracking down
the problem :).
If you are planning to use replication, you might want to check the
current requirements for the PK index.

hi
i read the follwing line in oracle 9i documentation,
Unique and primary keys can use non-unique as well as unique indexes. They can even use just the first few columns of non-unique indexes.
i am planning to use a primary key constraint enforced by the first few columns of a non-unique index.any feedback or advice or gotchas in having such a setup.
thanks
sai
