Oracle 9i Dbms-redefinition?
Oct 29, 2010
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.

Is it possible to change the datatype of a column in a table online, using DBMS_REDEFINITION?
If Yes, then which of the options will be used with DBMS_REDEFINITION package?

I need redefine a Materialized View (add some columns). I try it with:
drop materialized view TCPIP preserve table;
ALTER TABLE TCPIP ADD (SUM_IP_OUT_OF_SEQ NUMBER)
/
ALTER TABLE TCPIP ADD (SUM_IP_OUT_OF_SEQ NUMBER)
/
and than create a new MV:
CREATE MATERIALIZED VIEW TCPIP
ON PREBUILT TABLE USING NO INDEX NEVER REFRESH ENABLE QUERY REWRITE as
SELECT ...
But with Oracle error: ORA-12060: shape of prebuilt table does not match definition query
I check the new MV definition, it is contain the 2 added columns.

share what can we do to over come this issue?We are running 11.2.0.2 on IBM Aix. I am trying to do an redef and this is what i see:
Received an ORA-1555 error on a table redefinition with LOB segments.
ERROR at line 1:
ORA-12008: error in materialized view refresh path
ORA-01555: snapshot too old: rollback segment number with name "" too small
[code]...
As the ORA-01555 error does have a name we know that this is LOB related.We are using Automatic Undo mode and have RETENTION specifed on the LOB segments in both the source and target tables for the redefinion.The LOB segments in the source table are stored out-of-line (DISABLE STORAGE IN ROW) while the LOB segements in the target table are stored in-line (ENABLE STORAGE in row).There are a very large number of updates occuring on the source table. The table is quite large and the redefintion failed after 36 hours.
In oracle documentation we're finding conflicting information as to whether the UNDO_RETENTION database parameter affects the LOB storage RETENTION parameter, and therefore whether increasing our UNDO_RETENTION will be useful in this issue. The SQL manual indicates that it does affect this saying 'Oracle Database uses the value of the UNDO_RETENTION initialization parameter to determine the amount of committed undo data to retain in the database.'
Our current undo_retention is set to 21600.
How can we resolve this ORA-1555 error?

I performed the Table Redefinition process on one of my transaction tables. I wanted to redefine the existing table to a new table with partitions. Everything worked fine until i reached the last step where we had to drop the interim table. Now in between the redefinition , we created the interim table with partition along with the constraints and indexes and then atlast ran the "dbms_redefinition.finish_redef_table" proc to finish the redefinition.
And after that when I tried to drop the interim table , I am getting the below error message
"ERROR at line 1: ORA-02449: unique/primary keys in table referenced by foreign keys"
So this means all the constraints from my actual table were swapped with the interim table and hence I am getting this error.So is this a normal case or I have missed something while performing the redefinition? If thats normal then should i Just Drop table tablename CASCADE CONSTRAINTS?

At present we have a non partitioned table.
Can we apply redefinition and create range partition and hash sub partition on it?

I am creating the following dbms_sql procedure...
CREATE or replace PROCEDURE table_demo
(tabname IN varchar2)
IS
cursor_name INTEGER;
rows_processed INTEGER;
[code]...
There are no compilation errors.I call this code from the following anonymous block...
DECLARE
X CHAR:='T';
BEGIN
TABLE_DEMO(X);
END;
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?
some reference websites where I can get some details about how the scheduled jobs are executed?

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;

I saw bunch of other posts but I could find the post that exactly explaining about where the value returned as systimestamp / sysdate comes from or impacted Here is my situation I have an access to this db (let me call db A) and when I access it, I get following result. I don’t have full access to this db so I cannot experiment a lot here.
SYSTIMESTAMP CURRENT_TIMESTAMP LOCALTIMESTAMP DBTIMEZONE SESSIONTIMEZONE
--------------------------------------------------------- --------------------------------------------------------- ------------------------------------------------ --------------------- ----------------------------
27-MAR-13 02.31.55.041411 AM +00:00 26-MAR-13 07.31.55.041416 PM -07:00 26-MAR-13 07.31.55.041416 PM +00:00 -07:00
I’m in PST timezone.I have my db which I have full access as well as its host.I can make result like db A on my db if I started up db and its listener while TZ environment variable equal to UTC.Now I saw in other post that someone was trying to retrieve systimestamp value in a job executed via dbms_scheduler.run_job.
So I did that in two ways. 1 with use_current_session = true and 2 is false for the same.On my db, results are the same (both returns time in UTC) but on db A, I got UTC time when use_current_session = true and PST when use_current_session = false.
So questions are:
What could be the difference in setup between my db and db A?
Is there a query, logfile, or anything I should check to find out what can be the difference?
I tried to find the cause with my db and I could see the same result as db A which is to see UTC time if use_current_session = true and PST time if use_current_session = false by bringing up the db listener after I set TZ environment variable equal to PST8PDT. However this causes systimestamp from sqlplus session become also a PST time.
The reason I’m playing around with the setup and checking systimestamp value is because we are facing the situation where everywhere except pl/sql job submitted by enterprise scheduler service is pointing wrong timezone (PST instead of UTC)

I am calling one procedure through job and after submitting the job i am using commit. problem is when job close the session it commit the code which is inside procedure and as per my understanding in another session also, which i want to avoid .
my procedure is
Create My_proc is
Begin
Insert into my_table values(1,2,3);
End;
And my job proc is
Create my_job_proc is
Begin
dbms_job.submit(jobno,'my_proc;',sysdate,null,null,false);
commit;
End;
now i am calling my job proc is
Declare
Begin
my_job_proc;
End;
Now problem is once it finish, it will insert the data into my_table which i don't want until I call Commit.I already try 'Set autocommit off'

I need to identify, whether my current session is one of slave sessions scheduled as Oracle scheduler job via DBMS_PARALLEL_EXECUTE or not. I already succeeded using join of dba_scheduler_running_jobs, user_parallel_execute_chunks and v$session, but I feel that this is not optimal approach.

I've just installed an Oracle 11.2.0.1.0 64 bit server on my windows 7 machine in order to play around while using attempting to run
exec dbms_stats.gather_table_stats('eii','v2x4e')
I get the following:
ORA-20000: Unable to analyze TABLE "EII"."V2X4E", insufficient privileges or does not exist
ORA-06512: at "SYS.DBMS_STATS", line 20327
ORA-06512: at "SYS.DBMS_STATS", line 20360
ORA-06512: at line 1
My initial google searches indicate that I need the select any table and analyze any privileges. I don't think that can be right/appropriate - but I've granted them anyway to no avail.
Select * from user_tables
returns tables in the System and sysaux tablespaces, but not my own schema/tablespace?
