Provides access to some SQL Data Definition Language (DDL) statements 
  from a stored procedure. It also provides special admin operations that are 
  not available as DDLs. 
  
  The ALTER_COMPILE and ANALYZE_OBJECT procedures commit the current transaction, 
  perform the operation, and then commit again. This package runs with the privileges 
  of calling user, rather than the package owner SYS. 
Subprocedures: ALTER_COMPILE Compile the PL/SQL object. ANALYZE_OBJECT Provide statistics for the database object.
For full documentation of the packaged procedures above see the Oracle Manual:
"Oracle9i Supplied PL/SQL Packages and Types Reference"
or the book Oracle Built in Packages by Steven Feuerstein et al
