My VPD policies were causing troubles when I was running the Forms: ORA-28113 Policy Predicate Has Error . I could not easily figure out which Policy it was, as my data manipulation caused several triggers to fire that in turn performed queries and DML. So I wrote a simple procedure that can help me test all policies and find which ones are invalid.
It’s simple and really useful. Ideally it would disable all policies except the one being tested to be sure that any error is caused by that one. Feel free to add that functionality, I am under some time pressure right now.
create or replace procedure policy_tester is l_count number; procedure pl(p_text in varchar2) is begin dbms_output.put_line(p_text); end pl; begin for ply in ( select object_name, object_owner , policy_name , package from all_policies ) loop begin execute immediate 'select count(*) from '||ply.object_owner||'.'||ply.object_name into l_count; pl('Policy '||ply.policy_name||' on '||ply.object_owner||'.'||ply.object_name||' seems ok. ('||l_count||' records found)'); exception when others then pl('Error ('||sqlerrm||') in policy '||ply.policy_name||' on '||ply.object_owner||'.'||ply.object_name); end; end loop; end policy_tester; /

One thought on “VPD Policy Tester”
This is a very useful little script. A great idea, thanks for sharing it. If you could put it in a .sql file and add it to your site somewhere i will link to it from my Oracle security tools page. If you don’t have time I will add a link to this blog entry instead.
