Home -> Community -> Mailing Lists -> Oracle-L -> Advice for dblinks between two prod DBs.
Hey all,
I've been reading through the Distributed Database Concepts part of the 10gR2 Admin Guide to get a better understanding of how to setup dblink(s), which I've avoided since 7.4 (8.0?) when I first messed with them. After a developer inquired about using dblinks for our new ERP, I'm thinking I have a need for them now. Here's my scenario:
I have a million questions about distributed query and transaction performance, but first the setup. I want this to be usable, but flexible. My knee jerk says to create two dblinks for each app account -- one for queries, the other for DML. My main reason for this is security -- each dblink's remote account would need to be explicitly granted access to the specific ERP API views/packages needed. Is this overboard? One dblink for each app? Or one public dblink for all app accounts? <shudder>
I'm also looking for pointers to dblink hints and gotchas, like if I find an icky query running on the remote DB, how do I trace it back to the other DB (and, therefore, to the client)?. My search terms seem to be too generic to turn up anything of much use.
TIA!
Rich
