Thanks, yours and Andy's examples make sense but not really what I am looking for. Say I have user JEFF who wants to create or change a procedure that is owned under Schema B, but I don't want JEFF to be able to change any procedure under B. I guess maybe if I took your similar approach and created a procedure which had a parameter as a clob or external file which is code they wanted compiled and then did a execute immediate. But that is pretty cumbersome and my developers will give me a lot of grief. I wish you could just say something like this. Grant create any procedure under schema B to JEFF; Grant alter procedure b.my_procedure to JEFF;

Jeff,
You can go really crazy with this idea, but let's start with the concept of truncating a table in a production environment. You do not want everyone to be able to do it, and you certainly don't want to grant the DROP [ANY] TABLE privilege necessary to allow someone to truncate the table natively.
So, you create a procedure named TRUNCATE_TABLE_XYZ whose body contains the sole command "TRUNCATE TABLE XYZ". Then, you can grant EXECUTE on the procedure to AMY and AARON but not to BETSY and BOB. So now, AMY and AARON have the ability to truncate the table.
Now you can start to get fancier. Instead of a procedure per operation (as in this example), you can add parameters to the procedure. So, now instead of a procedure named TRUNCATE_TABLE_XYZ to truncate the table named XYZ and another procedure named TRUNCATE_TABLE_ABC to truncate the table named ABC, you can have a procedure named TRUNCATE_TABLE which takes a table name as a parameter and then executes the dynamic PL/SQL statement "EXECUTE IMMEDIATE 'truncate table '||in_table_name" where "in_table_name" is the input parameter to the procedure. So now AMY and AARON can execute "TRUNCATE_TABLE(in_table_name=>'XYZ')" and "TRUNCATE_TABLE(in_table_name=>'ABC')" if they are granted EXECUTE to it.
And you can keep getting fancier; maybe the TRUNCATE_TABLE procedure has some qualifying logic of its own, where it will only perform the requested operation during certain times of day? Or maybe it also logs the requested action as well as the outcome. And so on...
Does that make sense?
Hope this helps...

Jeff,
Encapsulate the commands you want to provide within a PL/SQL packaged- or stored-procedure. Then, you can control access to that the way you'd like. You can also build in auditing/tracking, etc.
Hope this helps...

Subject: developer access to alter procedure
I would like to give a developer access to alter a specific list of procedures/functions/packages from multiple schemas but I can think of a way to do it. I don't want to give him access to a whole schemas because there are other procedures he should not touch, and I don't want to give him the alter any procedure privilege. Is there any way to do this that I am not thinking of? How come Oracle doesn't have the command: Grant alter on to user; Jeff -- http://www.freelists.org/webpage/oracle-l
