David Dumb question. I always understood that: "Whenever possible, dbms_stats routines will run via parallel query". Is there a reason this doesn't work for you? Another idea. Instead of making dbms_stats run faster, consider whether you are spending too many resources analyzing. dbms_stats can use the GATHER STALE option. I think Wolfgang Breitling has stated that once his queries are operating satisfactorily he doesn't gather statistics any more.

I would just gather_database stats, but the request is that I use dbms_stats.gather_Schema so that the process can be broken down into concurrent sets and run concurrently(and with parallel). Does anyone have any advice, ideas or tips on how I might accomplish this? Here is what I'm currently using: select 'exec dbms_stats.gather_schema_stats(ownname=> ' ||chr(39)|| owner||chr(39)||' ,estimate_percent=> 10 ,cascade=> TRUE , block_sample=> TRUE ,degree=> 4);' FROM DBA_TABLES WHERE OWNER NOT IN ('SYS') AND PARTITIONED = 'NO' AND LAST_ANALYZED < SYSDATE - 14 UNION select 'exec dbms_stats.gather_schema_stats(ownname=> ' ||chr(39)|| owner||chr(39)||' , estimate_percent=> 10 ,cascade=> TRUE , block_sample=> TRUE ,degree=> 4);' FROM DBA_TABLES WHERE OWNER NOT IN ('SYS') AND LAST_ANALYZED IS NULL; Yes, I do know that the options clause will take care of some of the functionality that I am filtering via the predicate and I have plans to incorporate that feature.
