At the recent NYOUG conference, they were handing out special preview copies of Oracle 10g New Features by our very own Robert Freeman....  

Page 11 has a section entitled...Collecting Data Dictionary Statistics...this is done using the DBMS_STATS.GATHER_DICTIONARY_STATS procedure.  

Does that answer your question Patrice?

We had issues here with first_rows and all_rows when set in init.ora for 8i a couple of years ago... performance dropped significantly. During discussions with Oracle Support I learned that the data dictionary for 8i has to run in rule mode, I don't know if they changed that in 9i or 10G.  

Hopefully... 10G still has a data dictionary I imagine.

10g it won't be supported... wander when rule hints won't be used in E-Business Suite... 11.5.8 still has rule hints in some of the code.

OK, dumb question. Does this mean the rule hint won't be possible? Application I support mostly uses CBO but there have been cases where we had to resort to RBO hint. 'course it'll be some time before we can consider v10...

|Hi Jared,

|haven't seen it, too. But the fact
|was spreaded over the newsgroups.

|We still have some 3rd party apps that don't use 
|*any* feature above Oracle 7 (well, almost). Queries with 
|the RULE hint where it's not necessary. 
|But if we change a thing, support will be lost. 
|So we decided to rewrite the whole app. 
|Lucky me: enough work for the next years. 

|Greetings,
|Guido
