Edgar, I have heart a mention of this feature in LewisC podcast and also in Oracle > 11g new feature white paper. Oracle white paper says: > > With Oracle Database 11g, both patch set and release upgrades are now > significantly faster through the use of parallelism and delayed compilation > of PL/SQL objects. > > Apparently, Oracle Database 11g does this by recording dependency information at the granularity of the element within the object rather than at the whole object. For example dependencies on a procedure within a package is tracked rather than dependency on the package itself. Hence, if you This is what I know - I am sure the Gurus would like to comment. Maybe someone with a 11g database can post the description/selected contents of DBA_DEPENDENCIES and run the query below: select referenced_type, count(*) from dba_dependencies group by referenced_type; -- John Kanagaraj <>< DB Soft Inc http://www.linkedin.com/in/johnkanagaraj http://jkanagaraj.wordpress.com (Sorry - not an Oracle blog!) ** The opinions and facts contained in this message are entirely mine and do not reflect those of my employer or customers **
