RE: shared database sequence.

Do you just need uniqueness or do you need some correspondence amongst the databases?  

If so, how chunky can the correspondence be?  

If the database servers are reliably near each other in a network latency sense you would still have to decide whether the network latency of using a dblink to get sequence numbers from a different database is acceptable.  

If you don't need a correspondence, then you can maintain uniqueness by assigning something like a database number to each database and tacking a suffix on, so for example all the ids from database 3 end in 3.

Subject: shared database sequence.  

Hello List,  

Is it possible to share a database sequence between multiple databases? Not in RAC of course.

We are planning to have two databses exchanging information (replicating) using third party solution. But, stuck with the issues of sequences.  

Thanks
