Server Administration :: Dbms_metadata Giving Incorrect Results?

dbms_metadata is giving me code that will create more datafiles than the original, and furthermore won't run: firstly, because two files are named with a null string, and secondly because it includes RESIZE commands which won't work because they nominate OMF file names. Or is dbms_metadata unreliable?

We just upgraded to 11g and have run into incorrect results for some of our LEFT JOINs. If the table, view, subquery, or WITH clause that is being LEFT JOINed to contains any constants, the results are not correct.
For example, a test (nonsensical) view such as the following is created:
create or replace view fyvtst1 as
select spriden_pidm as fyvtst1_pidm,
'Sch' as fyvtst1_test
from spriden
where spriden_last_name like 'Sch%' ;
When I run the following query, I get correct results; that is, only those with "Sch" starting their last name are listed.
select spriden_pidm, spriden_last_name, fyvtst1_pidm, fyvtst1_test
from spriden
join fyvtst1 on fyvtst1_pidm = spriden_pidm ;
However, when I change the JOIN to a LEFT JOIN, the last column contains "Sch" for all rows, instead of NULL:
select spriden_pidm, spriden_last_name, fyvtst1_pidm, fyvtst1_test
from spriden
left join fyvtst1 on fyvtst1_pidm = spriden_pidm ;
We've discovered other quirky things related to this. A WITH clause with similar logic as the above view, when LEFT JOINed to a table will also cause the constant to appear in each row, instead of NULL (and only the value where there is a join). But when additional columns are added to the WITH, it behaves correctly.
This is easy enough to rewrite - but we have WITHs and views containing constants in numerous places, and cannot hope to track down every single one successfully before the incorrect results are used.
Finally, the NO_QUERY_TRANSFORMATION hint will force the query to work correctly. Unfortunately, it has a huge negative performance impact (one query ran for an hour, vs. 1 second in 10g).

I have the following DDL:
drop table tmp_guid;
CREATE TABLE tmp_guid (
c1 raw(16) not null
,c2 raw(16) not null
);
begin
[code]...
It seems that a combination of a unique index and extended stats are to blame. Removing any one of them causes the query to also produce correct results.Extended stats basically captures the fact that despite being unique, c1 depends on c2.

While I was debugging the code of already existing application (Oracle apps fnd_global package), I copied a package to make changes in it.
It was strange that with Original package fnd_global I am getting below error when I call it over database link:
"ORA-20001: Oracle error -20001: ORA-20001: Oracle error -2074: ORA-02074: cannot SET NLS in a distributed transaction
has been detected in fnd_global.set_nls.set_parameter('NLS_LANGUAGE','AMERICAN').
has been detected in fnd_global.set_nls."
PACKAGE CALLS ARE AS FOLLOWS:
Database 1 (Oracle Apps LSH module)
CUSTOM procedure to call CDR_PUB_API_GVA
has CDR_PUB_API_GVA
INITIALIZATION BLOCK OF CDR_PUB_API_GVA CALLS Fnd_Global.apps_initialize (when copied to fnd_global1, then it's call don't throw any error)
Database 2 (External application)
has dblink to Database1
calls custom procedure over dblink
While the copied package is not throwing any error (I copied fnd_global to fnd_globa1).

I installed 11.1.0.6. on Linux RedHat 5.5. Then upgraded to 11.1.0.7. However when I issue sqlplus /nolog and do select banner from v$version it shows 11.1.0.6. Although the install and upgrade were successful. I wonder why it does not show 11.1.0.7. I upgraded using the installer and not dbua could this be the reason why?

I've migrated from Oracle 9i to Oracle 11gR2, when i'm checking my application on Oracle 11gR2, i found that some of the query result are differed from the previous version of Oracle 9i, which is very illogical to me. I've checked the data for all related tables which are involved in one of the query. I've checked all indexes also. Still i'm not convinced that Oracle is doing anything wrong. I cannot recreate the whole scenario here, because of many tables involved in that query.
One of the sample query code.
select 'ProductMaster' producttype,e.schemecd,e.SCHEMESHORTDESC as SCHEMEDESC,to_char(e.schemefrdate,'dd/MM/yyyy')as schemefrdate, to_char(e.schemetodate,'dd/MM/yyyy') as schemetodate,e.mkid ,e.countrycd,e.statecd,e.districtcd,f.schemetype, a.productcd,a.packsizecd,a.packtypecd,a.sortorder1, a.countrycd,a.statecd,a.districtcd,a.p_uniqueid,a.mrp, (a.productcd ||'-'||b.countryname||'-'||c.statename||'-'||d.districtname|| ' -pkt.prc:'||a.pktprice ||' -mrp:'||a.mrp) as pcode

I have user U1 with dblink DBL1 (private dblink, not public).
CODECREATE DATABASE LINK DBL1
CONNECT TO U1 IDENTIFIED BY XX USING 'TNS1';
I have user U2 with dblink DBL2 (private dblink, not public).
CODECREATE DATABASE LINK DBL2
CONNECT TO U2 IDENTIFIED BY XX USING 'TNS2';
Both dblinks works fine, it means I can do select.
When I logged in with U1 and try to execute the following statement :
CODESELECT SYS.DBMS_METADATA.GET_DDL('DB_LINK',OBJECT_NAME)
FROM SYS.USER_OBJECTS
WHERE OBJECT_TYPE = 'DATABASE LINK'
AND OBJECT_NAME = 'DBL1';
I get ORA-31603 error:
CODEORA-31603: object "DBL1" of type DB_LINK not found in schema "U1"
ORA-06512: at "SYS.DBMS_METADATA", line 4018
ORA-06512: at "SYS.DBMS_METADATA", line 5843
ORA-06512: at line 1
same happens when I pass user name to get_ddl:
CODESELECT SYS.DBMS_METADATA.GET_DDL('DB_LINK',OBJECT_NAME, [b]USER[/b])
FROM SYS.USER_OBJECTS
WHERE OBJECT_TYPE = 'DATABASE LINK'
AND OBJECT_NAME = 'DBL1';
When I select from user_objects with the following query , it is there.
CODESELECT *
FROM SYS.USER_OBJECTS
WHERE OBJECT_TYPE = 'DATABASE LINK'
AND OBJECT_NAME = 'DBL1';
DBMS_METADATA.GET_DDL works for every other objects of U1 (tables, views, ... for example) except for dblinks. DBMS_METADATA.GET_DDL works for every objects of U2, includes DBL2.
I tried to add "select catalog role" to U1, even when I know that I need it only for objects from other users.
I tried to create DBL2 in U1 - same results.
I tried to re-create dblink using full connection string - with same result.

Target Database version/addition: 10.2.0.4.0 EE
Therefore, I did an export using Oracle Data Pump:

does it have to do with the VERSION parameter value? what can I check to investigate?

1)Want to perform an Export from a Production Schema and Import the results into Test Schema. BUT, do not want to export ALL objects from Production (only a subset of tables). Is this possible?doco on how to do this? (rather than a complete Export and then a complete Import).
2)I have 2 test instances of Oracle on the same development server, UNIT and SIT. Am using Oracle SQL Developer tool.
While in the UNIT instance, is there a way to select data from the SIT instance? An example of syntax to use?
3) Can tables in the UNIT instance be compared to tables in the SIT instance, through any existing Oracle utilities

Consider the statement below:
Update employee e
set e.dept_id = (select d.dept_id
from dept d
[Code].....
The above is not the exact code which I am executing but an exact replica of the logic implied in my code.
Now, when i display the value of 'rows_updated' it returns a value greater than 0,i.e 3 but it should ideally return 0
since there are no records matching for the condition:
(select d.dept_id
from dept d
where e.dept_name = d.dept_name)
So, I executed the statement:
select count(*) from employee e
where emp_id = 1234
and exists
(select 1
from emp_his ee
where e.emp_id = ee.emp_id)
and the result was 3 which is the same value returned by %rowcount.
why this is happening as I am getting incorrect values in %rowcount for the number of rows updated.

I currently have around 560 rows of bad data where
GL_Encumbered_Date and TO_CHAR(PRD.GL_ENCUMBERED_DATE,'YYYY' display correctly.
The problem lies in
PRD.GL_CANCELLED_DATE which displays correctly (example: 30-APR-10) but TO_CHAR(PRD.GL_CANCELLED_DATE, 'DD-MON-YYYY') for the same row displays as 30-APR-0010.
I have separated out the incorrect year with:
to_char(prd.gl_cancelled_date,'YYYY') where each of the 560 rows display 0010 instead of 2010. I am unsure if arithmetic with dates is allowed within SQL- but am curious if the operation date + number will result in a date.
If this is so, how could one go about taking 0010 as a date and add 2000 to create 2010 for: PRD.GL_CANCELLED_DATE.

When I run a menu (which was working fine yesterday and hasn't been changed in months) I click on an item and it runs the following
"
DECLARE
module_name VARCHAR2(125);
BEGIN
module_name := :GLOBAL.FORMS_PATH || 'covenants';
Open_Form(module_name);
END;
"
The module_name variable should be assigned the value 'covenants', because :GLOBAL.FORMS_PATH is '' (nothing). I stepped thru the code and in the debug system values window there is nothing in :GLOBAL.FORMS_PATH. But instead, it gives me: 'FORM_NAMEcovenants' where 'FORM_NAME' is the form the menu was called from.

I am working on the Reports Builder 10.1.2 at the Database Oracle 11.2.0. I have developed a report , which shows the page number at top right cornet. So I have selected a field and set the Source as "page Number". While I run the report through Reports Builder,it is properly displayed the page number. But while I copied the report to unix and run through "$ORACLE_INSTANCE/config/reports/bin/rwrun.sh", the page number is showing as 65536 . By changing the Source of the field to "Total Page" or "Physical page Number" make no difference.Every times It is showing the page number 65536 in the pdf output of the report.

How do you specify the value in START WITH dynamically during runtime. For example consider the bewlo scenario:
CREATE TABLE ISCT
(
ITEM_NO VARCHAR2(15 CHAR) NOT NULL,
ITEM_TYPE VARCHAR2(3 CHAR) NOT NULL,
ITEM_TYPE_SCO VARCHAR2(3 CHAR) NOT NULL,
[Code].....
Now if you create a view:
create or replace view test_v
(ITEM_NO, ITEM_TYPE, ITEM_NO_SCO,ITEM_TYPE_SCO)
as
SELECT T.ITEM_NO, T.ITEM_TYPE, CONNECT_BY_ROOT T.ITEM_NO_SCO,T.ITEM_TYPE_SCO
FROM
[Code] .......
Then run the below query:
select * from test_v where item_no_sco = '00245905'
--
the output is got within a second. but the real scenario is that both table icont and isct have millions of rows. In that case even this small query of the view takes 10minutes as there a FULL TABLE JOIN.
How do I give the START WITH in the view to make it faster i.e. even with millions of rows the output of this comes in seconds:
SELECT T.ITEM_NO, T.ITEM_TYPE, CONNECT_BY_ROOT T.ITEM_NO_SCO,T.ITEM_TYPE_SCO
FROM
(
SELECT NVL(C.ITEM_NO_CHILD, I.ITEM_NO) ITEM_NO, NVL(C.ITEM_TYPE_CHILD,
I.ITEM_TYPE) ITEM_TYPE, I.ITEM_TYPE_SCO, I.ITEM_NO_SCO
[Code] .......
