Sorry, not true. From at least 7.2.3 (the oldest I have here) there was no table-level locking for any analyze statement.

As for the preferment for estimate, Oracle has the last laugh - if you estimate on a percentage greater than 50% or specify rows greater than half the number of rows in the table, Oracle analyzes the entire table.
