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 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'
We created a job yesterday which will call the below procedure. if we start this job, it initiates 92 sessions parellely. How it is initiating 92 sessions parelley?
procedure prc_HECTOR_CIDB_IN_PURGE
IS
cursor CUR_PROC is
select rowid from CUSTMODEL.HECTOR_CIDB_IN where PROCESS_FLAG in ('Y','F');
TYPE TYP_CUR_DATA IS TABLE OF ROWID INDEX BY BINARY_INTEGER;
v_typ_cur_data typ_cur_data;

There is a detail table
There is a summary table
During batch process record is entered in detail table as well as summary table.
The process first checks if record exists in summary table for same group_no and if 'yes' then "updates" the record with the newly added amount (sums it) else inserts a new record
Whereas in the detail table it inserts the record directly
detail table :
group_no doc_no amount
101 doc1 100
101 doc2 200
102 doc3 300
102 doc4 400
summary table :
group_no amount
101 300
102 700
Now if the batch process runs in parallel, (out of many) two different sessions insert same group_no; This is because while sesond session inserts a record, first session inserting the same record (group_no) has not yet committed ; So second session Not knowing that already there is same Group_no (101) inserted, again inserts another record with same group_no rather than summing it.
Can it be solved without using temp table, select for update?
If we have not set parallel degree for a table then we can ( try to ) force parallel execution on a table using a parallel hint Does this 'parallelism' works on the index search in the query as well?
In which situations non-parallel non-partitioned table but parallel index (degree>2) will facilitate a query?
What is slave process? why we use slave process? when it is used?

I'm working with old code that uses dbms_sql.execute to build/execute dynamic sql. In our case, the user can select varying columns(I think up to 20) with different where conditions as needed.
After building the sql, here's an example
WITH ph AS
(SELECT ph.* FROM po_header ph WHERE 1 = 2),
pf AS
(SELECT DISTINCT pf.order_id, pf.fund
FROM po_fau pf, ph
WHERE 1 = 1
AND ph.order_id = pf.order_id
[code]....
Where table records for
po_header = ~567746
po_fau = ~2153570
and PK "order_id" is a NUMBER(10) not null and a snippet of the code looks like
nDDL_Cursor := dbms_sql.open_cursor;
dbms_sql.parse(nDDL_Cursor, sSQLStr, 2);
FOR x IN 1 .. nCols LOOP
sCols(x) := '';
dbms_sql.define_column(nDDL_Cursor, x, sCols(x), 100);
END LOOP;
nError := dbms_sql.execute(nDDL_cursor);
why when the "execute" statement is fired off the elapsed time takes ~4.5 seconds but If I change "1 = 1" above to "1 = 2" it takes ~.2 seconds. If I run the above query interactively it takes ~.2 seconds. Shouldn't the above query when joining
ph.order_id = pf.order_id
return zero rows back instantly or does the "dbms_sql_execute" do some other type of parsing internally that takes cpu time.
We can execute dynamic sql using both execute immediate and ref cursor..But what is the difference between the two and performance-wise which is better?

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.
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?

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)
