Re: create table and create index monitor or nomonitor deprecated in 10g?

You can turn monitoring on or off, at least for tables, database wide or schema wide with dbms_stats.alter_database_tab_monitoring or alter_schema_tab_monitoring respectively. 

As for ASMM, can anyone give me a good reason for using it?

This 10g param allows you to do what you used to be able to do in 9i with alter 
table (no)monitoring, but not at table level any more; it's system wide either
all monitoring or all nomonitoring. But I think it¡¯s still better to disable
this parameter and leave statistics_level to typical than set statistics_level
to basic when you want to disable table monitoring. Documentation writers must
have a dilemma, though; they probably wish the first underscore were dropped.


There's at least one exception.
If you are stuck on <http://10.2.0.2>10.2.0.2 (not allowed to upgrade) then you best not 
use ASMM, and have statistics_level = basic, as well as db_cache_advice=off.
While benchmarking a <http://10.2.0.2>10.2.0.2 database a nasty performance bug appeared.
