Hi,

I am facing a very strange problem.

Oracle 7.3.4.4.1 and HP 10.2

I do an analyze of a huge table (more than 46 million records) . The query which hits this table and 2 other table has an RULE hint .

On the day analyze fails on the big table, performance is very very slow . But with analyze performance is ok.

With RULE shouldn't oracle overrule the statistics and take the hint only. Why does it seem to be checking statistics .

The init.ora value is choose .
