SQL & PL/SQL :: Using DBMS-METADATA To Transform Tablespace DDL?
May 18, 2010
I'm currently busy with database consolidation, so I'm searching for a solution to generate some useful DDL to prepare the new target database before importing the application's data. This should include TABLESPACE DDL and all additional users with their grants.
So first I thought of developing a simple script, which will create the CREATE TABLESPACE DDL but with transformed datafile paths.But my throws some errors and I don't understand why:
ORA-31604: invalid NAME parameter "STORAGE" for object type TABLESPACE in function SET_FILTER
declare
l_hObject NUMBER;
l_Objddl CLOB;
[code]...

I have a problem with DBMS_DATAPUMP.metadata_filter.Let's suppose that I need to export a huge list of tables (a,b,c,d,e,f,g,h,i...). Let's suppose that the list is dynamic do NOT want to use
DBMS_DATAPUMP.metadata_filter (handle => h1,
NAME => 'NAME_EXPR',
VALUE => 'IN (''a'', ''b'', ...)',
object_type => NULL);
In my_export_table there is the list:
CREATE TABLE my_export_table
(
EXPORT_OBJECT_NAME VARCHAR2(50 BYTE)
)
Now I'm trying to use this form:
DBMS_DATAPUMP.metadata_filter (handle => h1,
NAME => 'NAME_EXPR',
VALUE => 'IN (SELECT a.export_object_name FROM my_export_table a, user_objects b WHERE a.export_object_name = b.object_name AND b.object_type = ''TABLE'')',
object_type => NULL
);
but it results in error.
Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA
ORA-39125: Worker unexpected fatal error in KUPW$WORKER.GET_TABLE_DATA_OBJECTS while calling DBMS_METADATA.FETCH_XML_CLOB []
ORA-00942: table or view does not exist

We are migrating one of our databases from linux to AIX (testing phase). We're using transportable tablespace for the same. All steps are done and we're stuck during importing the metadata. While importing metadata we require to mention fully qualified datafile name which has to be plugged. The number of datafiles is 309 and the name of the all the datafiles has to be in one line. Now if we try to write it in one line using vi editor, the editor gives error 'ex: 0602-140'.
Is there a way by which we can overcome this situation?

I need trasform information from table A to table B. Table A is refreshed every day, Table B needs record all the information, including records nolonger existing in TABLE A. I would like to use one SQL to complete the operation. The merge works only for insert and update, but not for delete.
Here are the structure of the tables:
Create TABLE A
(
course_number int;
course_txt varchar(20);
);
[Code]...
The record of tables will be as following:
On May 1, 2012
Table A.
100 math
200 english
500 social
Table B.
new 100 math May1, 2012

these are the sample data :
CREATE OR REPLACE TYPE CourseList AS TABLE OF VARCHAR2(64);
CREATE TABLE department (
courses CourseList)
NESTED TABLE courses STORE AS courses_tab;
INSERT INTO department (courses)VALUES (CourseList('1','2','3'));
[code]....
The query returns the correct data, CourseList that are not subset of any other CourseList of the table.
I am trying to convert this not exists in a left outer join query to check if the performance is better, but I don't know how to do it.
I was making some variations of this code :
select d1.courses c_1, d2.courses c_2
from department d1,department d2
where d1.courses<>d2.courses(+);
but it is now working.

I'm trying to get the Create-Statements of all tables of several schemas:
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name,'<schmema>')
FROM (SELECT TABLE_NAME, OWNER FROM SYS.ALL_TABLES WHERE owner='<schema>') u
Is there a way to create a loop to handle several schemas listed in a array, for example?

I have to build something like an export-interface-mappingtool. So user defines more or less a query and I have to display the attributes of this query to enable a mapping.
If I build up a ref cursor fom this query, I did not find the possibility to read its metadata (mostly Type/length is enough).
What I do not want to do is creating a temp. table or parse the query string to derive it from the dictionary.
Is it possible at all to get the metadata of a dynamic SQL ?

I am using the dbms_xmlgen.getXMLfunction to get the result of any query in xml format.
With this XML I also want the metadata information about all the fields used in the query (passed to getXML function). Is it possible and how can I achieve this.
I tried to Google it but couldn't find any solution , it's easy to do it in java where I can get the resultset meta data from the resultset but I have to do it in Oracle function since I want the result in xml format and want to use the oracle XML API.
You may think why I need metadata , the reason is the application will later use this information to sort the data contained in these fields according to their data type provided to.

A function returns the comments of all objects of the schema using metadata api. I used DATABASE_EXPORT as object_type for open function. which name (eg: base_object_name, base_object_schema...) should i use to get comments of single object. My code is..
1 CREATE OR REPLACE function f_depen_obj
2 return clob
3 as
4 a number;
5 b number;
[code].....
I got comments of all objects when i commented 11th,12th lines. Now i want the comments of EMP table of SCOTT schema. I got the following error ..
SQL> select f_depen_obj from dual;
ERROR:
ORA-31603: object "EMP" of type TABLE not found in schema "EMP"
ORA-06512: at "SYS.DBMS_METADATA", line 1546
ORA-06512: at "SYS.DBMS_METADATA", line 1583

ORA-06512: at "SYS.DBMS_METADATA", line 3784
ORA-06512: at "SCOTT.F_DEPEN_OBJ", line 17
no rows selected...i got output (comments of single object) when i use COMMENT instead of DATABASE_EXPORT in open function(line no: 9). But i need to use DATABASE_EXPORT as a object_type. Which name is suitable for set_filter procedure instead of 'NAME'?

I'm using Oracle 11g enhanced ADD COLUMN Functionality. Adding new columns with DEFAULT values and NOT NULL constraint no longer requires the default value to be stored in all existing records.
Sometimes we change DB columns from NOT NULL with DEFAULT to NULL with DEFAULT. This operation "materialize" column default. Is there an easy way (Dictionary view) how to find, that COLUMN default value is stored as metadata or is "materialized" ?

Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.

I am trying to redefine a table as to get clear of the thousands of chained and migrated rows. The darn table contains a lob column.I am trying to complete the process with the dbms_redefinition package.
I've createad the temporary table with all option to nologging. I've started the redefinition at midnight and it not yet completed and I can't find why it is taking so long. I've done the process with a table, similar in size in a Dev environement and it took at most two hours. In production, the process has been going on for 10h30 now.
I can see my tablespace size increase from time to time and when I querry the dba_segments to find out the size of both tables my temporary table is now 4 times the size of the original table.

This also compiles successfully and without any errors. It runs properly as wellHowever when I run 'select * from T'. Then system throws up the error of table or view does not exist.

Database 1(sm01):
=============
oracle, 9.2.0.6
there are 4 jobs scheduled in oracle dbms_job. 3 jobs will run everyday at 4.00AM. 1 job will run at every hour.Daily jobs are running fine. But hourly job is not executing automatically. If forced (exec dbms_job.run(<enter here job number>), this execute fine.
job_queue_processes=5
total jobs in schema=2503
total jobs in db = 2614
Even there are many jobs scheduled, next_date for 2234 jobs are lesser than the sysdate. Again in 269(2503-2234) jobs, 2265 are having NULL in the interval column.
Database 2(sm02):
=============
oracle, 9.2.0.6
there are 4 jobs scheduled in oracle dbms_job. 3 jobs will run everyday at 4.00AM. 1 job will run at every hour.All the jobs are not running automatically. If forced (exec dbms_job.run(<enter here job number>), these execute fine.
job_queue_processes=5
total jobs in schema=7
total jobs in db = 7
I planning to follow the below steps to avoid the above issue.
1.) Restart the job queue process by executing alter system set job_queue_processes=0
2.) Increase the value for the job_queue_processes.
3.) Restart the database
But I got stuck in the 2nd step. what value I need to put for this job_queue_processes parameter?

Under what userid(privileges) does a scheduled DBMS Jos run, is it under the same user that scheduled the job?
Does oracle internally log in(opens a new session) in order to run a scheduled DBMS Job?
