BEGIN
DBMS_RLS.ADD_POLICY (
object_schema => 'scott',
object_name => 'orders_tab',
policy_name => 'orders_policy',

policy_function => 'get_user_orders',
statement_types => 'select');
END;

Security :: Virtual Private Database Update Policy On Complex Views

Aug 21, 2013

1)I have created a complex view, and created an instead of trigger on this view

example:

create or replace trigger tr_x instead of before update on test_view_name for each row
-------
2) I have created an update policy on this view

DBMS_RLS.ADD_POLICY (
object_schema := schema_name,
object_name := name of the view,
policy_name := ploicy name,
function_schema := func schema name,
policy_function := pkg_test.fn_get_where,
statement_types := 'UPDATE',
update_check := TRUE,
policy_type := dbms_rls.dynamic);

3) function pkg_test.fn_get_where, which is used in the policy function always return 1 = 2, so that update should fail.

4) Now I will issue an update statement on the view test_view_name

update test_view_name set test_col = 1;

but still it updates the records, though update policy returns the where cluse 1 = 2

same where clause for select policy works perfectly fine.

Networking And Gateways :: Testing Private Database Link With Same Name As Public

Oct 13, 2010

We are currently replacing all public database links with private db links in our prod environment. The requirement is

1) private db link name should be same as public
2) Need to create and test out private db links before we can drop public db links.

How can we test out private db links while public db links are still there with the same name?

when I execute SELECT * FROM DUAL@DBLINK from user who created this private db link, which db link it will be using- public or private?

Private Strand Flush Not Complete

Feb 5, 2013

The "private strand flush not complete" is a "noise" error, and can be disregarded because it relates to internal cache redo file management.

However this "private strand flush cannot complete" error is sometimes accompanies by a hung database.

These are quotes from MR Burleson himself .

But can this be really ignored as it's also mentioned "hung database"

I'm making a function A that does many calls to procedures in an other package B. To make this function more readable, I'd like to specify synonyms for the procedures in B. I only need the synonyms inside this function, I don't want to make database synonyms.

For example:

Nov 28, 2012
