Re: Oracle/SQLNET Link Slowdowns

Are you running queries with tables in the local and the remote database?

Is this the case the sql-net link breakes down the indexes usage if you use more than 1 table in each. A way around this is the hint which causes an index search (maybe not the one you want ,but index!!)

select /*+ ORDERED */
