You're exactly right. There is another script that gets run by dbmspool.sql (prvtpool.plb). I see the "Package body created." message in a previous comment, but at any rate I just re-ran it. Here's the output I got: SQL> @dbmspool Package created. Grant succeeded. View created. Package body created. Thanks David.

Look inside the script and you'll find only a CREATE OR REPLACE PACKAGE ... command; there will also be a .plb file in the same location which will create the package body to match the specification. The ?/rdbms/admin/dbmspool.sql script which Kerry used creates the package spec and calls the wrapped script to create the corresponding package body. All I see in your posted output is 'Package created.'; there should also be the following messge: "Package body created." for this to function correctly. If you can't find a corresponding .plb file for the dbmspool11g.sql script I suggest you run the listed dbmspool.sql script to get the spec and body created correctly.

Sorry. The file that I executed was called called dbmspool.sql (the back ported version) not dbmspool11g.sql.
