Hi, Oracle 817/Solaris 8.
Users are doing select joining using the PKs of 2 partitionned tables. Partitionned key and the primary key are the same. The access plan is a nested loop with a full table scan on the first table which hold 700 000 rows. The block size is 16K, I assume that's why Oracle is doing FTS. By using optimizer_index_cost_adj, I can make Oracle use the PK of the first table. I've used 50 as a value for optimizer_index_cost_adj. Is that too much ? Where can I get some metrics on that parameter ?
