Dba_dependencies views

hi,
i was reading oracle doc about dba_dependencies and found it contradicting. Below mention that but the column of the views allows one to do
- REFERENCED_LINK_NAME VARCHAR2(128) Name of the link to the parent object (if remote)
- SCHEMAID NUMBER ID of the current schema
ALL_DEPENDENCIES describes dependencies between procedures, packages, functions, package bodies, and triggers accessible to the current user, including dependencies on views created without any database links. This view does not display the SCHEMAID column.
http://docs.oracle.com/cd/B19306_01/server.102/b14237/statviews_1041.htm

Please see below link which could be helpful for your issue:

Query to find dependency of an oracle VIEW

Hi,
I'm using oracle 10g database.
DB name is - ORCL
ORCL DB consists two schemas - Schema1 and Schema2
I have one Oracle view called VIEW1 in Schema1.
I need to find whether Schema2 uses VIEW1 in any of the Tables,views or Programs owned by Schema2.
Is there any query available to find this one?
Regards,
Karthik

How about querying the dba_dependencies view?

Can statements inside a package refer to database links

Hi all
I was just curious to know, what will happen in this case
CREATE OR REPLACE PACKAGE BODY "TESTUSER"."TESTPKG" as
procedure testproc is
n number := 0;
begin
select count(*) into n from ps_tab@dblink;
end;
end testpkg;';
Is it valid to have dblink inside a package body?

RegardsSure it is. You can have a database link inside a package code. Moreover, you'll get the name of that database link in the REFERENCED_LINK_NAME column of the DBA_DEPENDENCIES view

Sequence Names And Triggers

I am trying to link my sequences with my triggers. I have looked in sys.obj$, sys.seq$ and sys.trigger$ but the obj# doesn't match in triggers and seq$.
What I am trying to do is write a script that will update the sequences to the max vaule in a table. I have 125+ seqences and do it by hand will not work. I can get the max value but then I need to create or replace the sequence with the new one I don't just want to updated it.

Have you looked at dependencies$ or the dba_dependencies view? It should provide information about the trigger dependencies including the sequences.
Hope this helps.

Invalid status after successful run of procedure

I have procedure, which gets invalid after a successful run, i.e. desc procedure_name-status invalid.how can i over come this??

are you performing any DDLs inside your procedure?
Such as dropping,altering a table or recreating a view the SP refers to?
Please query DBA_DEPENDENCIES view for getting the list of objects your SP depends on. If you are modifying any of these objects inside your SP then it will become invalid after execution.

SQL to find the object dependencies

Is there any sql that can fetch all the dependencies information for any given object ++recursively++. The example given by oracle creates some storedproc/tables to get this info. But i believe that some oracle-gurus should be able to accomplish this using sql only.
thanks in advance.

But i believe that some oracle-gurus should be able to accomplish this using sql only.Interesting. Why do you believe this? Do you think we know more about the Oracle database than Oracle itself?
The problem is, Java. The introduction of Java into the database also introduced circular dependencies. These are not resolvable by tree-walking the DBA_DEPENDENCIES view. So, if you're not using Java then you're laughing. But if you are using Java in the database then I'm afraid you'll just have to build those tables.

Topic on Certification exam 1z0-146

Hi folks,
About 1z0-146 (Advanced PL/SQL ) exam topics, what should be a more detailed description of this topic :
Analyzing PL/SQL Code
[] Run reports on source code
to what package or utility does that topic make reference ?
thanks in advance.

I expect that would refer to a familiarity with the DBA_SOURCE, DBA_PROCEDURES, and DBA_DEPENDENCIES views.

Drop unused stored procedures

hi,
i need to drop unused stored procedures from our Oracle9i database.
How do I check and confirm that the stored procedures are no longer used by the application?
Our application is using jsp, servlet and ejb. Some stored procedures might also be called from other stored procedures, triggers and PRO*C programs.
best regards,
dayang

You are snookered in the absence of adequate documentation.
Some stored procedures might also be called from other stored procedures, triggers and PRO*C programsThat's the easy bit - you can find which database objects use other database objects using the USER/ALL/DBA_DEPENDENCIES views. But programs outside the database? No chance.
If you want to make yourself unpopular yoy could invalidate every single stored procedure and see who screams but that's not user friendly - besides some packages might only be used once a quarter, once a year even - financial routines are the obvious example.
If you have logging in place you might try switching it on, but I suspect you don't have that.
In short, if you don't know who's using a package you are better off leaving it in your schema. Just make a note for yourself to properly document your next system.
Cheers, APC

Database Dependencies tool

Hi,
Is there a tool you would recommend that provides an interface to show column dependencies in a database and in depth relationship diagrams?
Thanks for your feedback!

Do you mean a schema relationship diagram? Visio (professional edition) does a good job - all you need is the ODBC data source.
On the other hand if you mean dependencies on an object see the DBA_DEPENDENCIES view.

Triggering on when objects are INVALID

Hi, I'd like to have a trigger which compile an objects right after the object's status changes to INVALID. How can I do it ?
Is there any trigger event ? or should I use audit ?

Is there any trigger event ? or should I use audit ?It's possible to have INVALID objects when making change on an object without checking its dependencies. So before making any change in the production database, you HAVE to be sure that no any objects will be INVALID by checking its dependencies from DBA_DEPENDENCIES view
There're generally two ways to be notifed when there are an INVALID object in any database
The first method is using OEM. Go to Administration->Metric and POlicy Settings-> and set the value for the Owner's Invalid Object Count metric and change Collection Schedule to any time you want
The second method is writing a shell script which queries (each 10 minute for example) all your databases (using status column of the DBA_OBJECTS view) and send you email or sms message when finds any INVALID object

I want to know the dependencies

Hi,
I have one Package , in that package lot of procedures and function. i want to know the each procedure any dependencies is there.
How to find out dependecies for each procedure and function and package wise.
Is it possible to find procedure wise are only possible package wise.and also how to find each procedure is valid or invalid.urgent.
Thanks

[email protected] wrote:
urgent.That's typically a rude thing to say around here in a forum of volunteers.
As far as answering your question, I recommend looking at the DBA_DEPENDENCIES view.
If the procedure is defined inside a package then it will be listed at the package level in the DBA_DEPENDENCIES view.
HTH!

DBA_SOURCE / DBA_DEPENDENCIES

Hi
I am trying to find dependencies for package using dba_dependencies.
It gives me all the dependencies (tables and objects) used inside the package.
Is there a way to find attribute dependency and procedure name in a package
table_name / column_name / package.procedure line text /
Thanks

look at that:

Oracle has a utlity that does something similar, that can be installed
by running utldtree.sql. It includes a deptree_fill procedure. With a
little modification of the deptree_fill procedure, you can make your
own reverse_deptree_fill procedure, that should do about what you want.
You may want to add some additional modifications or filter the result
set when you query. Please see the demonstration below.

Confused ... ALL_DEPENDECIES view does not contain indexes?

I try to generate a installation sequence for all my objects, for this I experimented with the all_dependecies view
1st generate a table with all objects:
<pre>
drop table rank_sources;
create table rank_sources as
select rownum as rn, object_name, object_type, owner from all_objects
where owner = 'SYS';
commit;
select * from rank_sources;
</pre>
afterwards fire a pl/sql
<pre>
set serveroutput on
declare
cursor l_cursor is select * from rank_sources for update;
l_found boolean := false;
begin
for src in l_cursor loop
l_found := false;
for dep in (
select level, referenced_name, referenced_type
from DBA_DEPENDENCIES
where owner = src.owner
and referenced_owner = src.owner
start with name = src.object_name and type = src.object_type
connect by name = prior referenced_name and type = prior referenced_type
loop
l_found := true;
update rank_sources
set rn = src.rn - dep.level
where object_name = dep.referenced_name
and object_type = dep.referenced_type;
end loop;
if not l_found then
update rank_sources
set rn = -9999999999 where CURRENT OF l_cursor;
end if;
end loop;
commit;
end;
</pre>
As you can see, there are potentially indexes with a lower rank than their table. When you do a
<pre>select * from all_dependencies where type like '%INDEX%'</pre>
the result is NULL - I am really confused why indexes are not referencing to their tables?? So in case of Index I have to query seperatly all_indexes.
But when you look at the all_dependecies view definition you can see, index as an expected type - is this a bug? I use Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
<pre>
SET DEFINE OFF;
DROP VIEW SYS.ALL_DEPENDENCIES
/* Formatted on 20.10.2010 12:31:15 (QP5 v5.149.1003.31008) */

</pre>
Thanks
Chris

Ok, so what I have done so far - to get a solution for my requirement - I created a sys view like this:
<pre>
create or replace
view REALLY_ALL_DEPENDENCIES as
select *
from ALL_DEPENDENCIES
union
select owner, index_name, 'INDEX', table_owner, table_name, table_type, null, null
from all_indexes
union
select p.owner, p.table_name, 'TABLE', f.owner, f.table_name, 'TABLE', null, null
from all_constraints p
join all_constraints f
on F.R_CONSTRAINT_NAME = P.CONSTRAINT_NAME
and F.CONSTRAINT_TYPE = 'R'
and p.constraint_type='P'
</pre>
Since union is checking for duplicates, it should be harmless to use this view from now on :-) ... ok, performance is not really good, but I do not use the view every minute - maybe once a day.
Thanks and cheers
Chris

Query to get the name of the tables used in a View?

Hi,
Could you please help me in getting the name of the tables used in a perticular view?
Please help me out...
thnx in advance.
Thnx,
Bits
Edited by: Bits on Sep 14, 2009 2:15 PM

There is no data dictionary table that stores this directly.
- You could get the DDL used to create the view and parse that SQL. Depending on how complex the view might be, this could be relatively easy or highly complex.
- You could get a recursive list of the objects that the view depends on (from ALL_/USER_/DBA_DEPENDENCIES) and trace those dependencies back to all the tables that the view depends on. If your view calls functions, however, this may or may not be what you're looking for. If you are selecting from just one table in the FROM clause but you are calling a function that references a dozen tables, do you want one row? Or thirteen? What about tables referenced in a correlated subquery in the WHERE clause?
