I have just migrated database to 11.2 ..Migration is successfull and now database is in open mode working fine.BUT i m getting following mesage in alert log file
"Time drift detected. Please check VKTM trace file for more details."I m using windows platform.
I've got a query running a select count (*) over a table. The default plan takes in the order of 15 minutes to return, a hinted plan to use a different index takes 3 minutes to return.
Unfortunately I cant get at the index stats and a few other areas which I suspect may be key here.When running autotrace against the two queries I see fairly different values as one would expect.
Query
select count (*) from fulfilmentitem bfi where created >= sysdate-30 AND bfi.status = 'FA' AND bfi.fulfilmentmethod = 'D'

[code]....
IDX_FULFIL_METHODSTATUS is across FULFILMENTMETHOD & STATUS in that order.
IDX_BFI_CREATED is on CREATED and is approx 70% of the size of the other index
The row counts estimated in the explain plan are out, the count(*) comes in at 32.8k rows.As you will have seen, the fast run shows a pretty significant consistent get increase compared to the slow run and a decent though not dramatic physical read drop.
My uncertainty is around if these changes in consistent get/phys read values would typically be enough to suggest the real time improvements I'm observing or if other (albeit perhaps temporary) factors are involved. It is a prod OLTP environment so the data will be rapidly changing and that may be a factor.
I know it can never be an exact science without intimately knowing the hardware/current loads etc but I also know that there's enough experience on these boards to have a loose handle on if the time shifts between queries are likely (or not) to be reflective of the stat changes or if those differences alone shouldn't (or typically wouldn't account) for it.
I'm thinking about instructing the query to ignore its original plan but am hesitant to do so without being a little more confident that it's not just a timing thing or something other than the change of index approach which may be causing the improvement. the autotrace stat changes observed I couldn't put my hand on heart say "yup - that change is good, ignore the default index all the time for this job".

I'm having issues with users logging into Oracle. I installed it on Ubuntu 12.04 running Oracle 11.2 XE. If i am root, i can run sqlplus just fine and log in. But when I use a regular user account and run sqlplus, it will just stay blank. No error messages or any feedback. I echo $ORACLE_HOME and echo $ORACLE_SID and they come back exactly as they do under the root account. My path is set up just like root has it.
It almost seems like a permission issue but even when i try sqlplus /nolog it stays blank.

I have a query which takes 5 minutes when run through the java app which uses hibernate. I've cut and pasted the SQL directly from hiberate trace file and run it in sqlplus/sqldeveloper and it runs instantly (0.01 seconds)(uses the index all ok and explain plan looks good - see below.) I don't know how to get the explain plan when it's running through the app or why it should be any different anyway as the query is identical.
My query is as follows:
SELECT /*+ INDEX (SPD SPD_SEQ_CODE) */ SPD.*
FROM SEQ_ADDR_DATA SPD, SEQ_ADDR_LEVELS SPL
WHERE SPD.SPVR_ID = '10'
AND SPL.SPLE_ID = SPD.SPLE_ID

I have a procedure in the live environment , which operate in 2 mode.
1 regular load at 10 min
2 nightly
The code is same except they set the last loaded time for both in 2 dfferent rows, so that next time run will get incremental data.
I can trace this procedure on mode 1 that is is scheduled but unable to find how the 2nd one is getting trigger every night. there is no jobs corresponding to that. Is there any way i can find which method is trigger the procedure during night.
un-documented parameter _trace_files_public / I want to set this to true so my app team can review trace files. better way to proceed to open read permissions for non oracle users.

We are running Oracle 11.2.0.3 on a Windows 2008 R2 Server with an app server on the same. Our app has a search function that has recently started timing out on us. Sometimes intermittently but often now. I've ran a trace in our dev environment, below code, in an attempt to track down the issue but I'm finding very little useful information in relation to the errors I see in the trace file below.

I am trying to generate a trace file from a piece of code executed by java server. What I asked the java developer to do is to place this block immediately after establishing a connection:
BEGIN
EXECUTE IMMEDIATE 'ALTER SESSION SET TRACEFILE_IDENTIFIER = ''M1''';
dbms_monitor.session_trace_enable(waits => FALSE, binds => TRUE);
END;And at the end of the logical java block of code:
BEGIN
dbms_monitor.session_trace_disable;
END;
What I want to know is how many rows the java server fetches after executing one particular select statement, because they complain about receiving less in count rows from the select statement than expecting. For example, if I execute the same sql query in sqlplus session, then I fetch let's say 1000 rows. When the same query is executed from java side, the fetched rows are less in count, let's say 500.And because I doubt it, I wanted to trace to see what actually is executed and how.the excerpt of the trace file I see exactly the same query which I execute myself in a sqplus session.is no fine-grained control on the udnerlying tables in the query.
And my question is, how to interpret the FETCH phase of the cursor (for the select statement)?example, if I see one FETCH for this cursor, does this mean that the java server has fetched only one row?If I see 100 FETCHes, does this mean they fetched 100 rows from the cursor?
Here is a short excerpt from the trace file (don't crucify me for the query and the obvious denormalized design of the tables, this is not invented by me):

I am working on tuning the performance of one of the concurrent request in our 11i ERP System having database 11.1.0.7
I had enabled oradebug trace for the request and generated tkprof out of it. For below query which is taking time , I found that , in the trace generated , wait event is "db file sequential read" on an PO_LINES_N10 index but in the generated tkprof , for the same below query , the full table scan for PO_LINES_ALL is happening , as that table is 600 MB in size.
Below is the query ,
===============
UPDATE PO_LINES_ALL A
SET A.VENDOR_PRODUCT_NUM = (SELECT SUPPLIER_ITEM FROM APPS.IRPO_IN_BPAUPDATE_TMP C WHERE BATCH_ID = :B1 AND PROCESSED_FLAG = 'P' AND ACTION = 'UPDATE' AND C.LINE_ID =A.PO_LINE_ID AND ROWNUM = 1 AND SUPPLIER_ITEM IS NOT NULL),
LAST_UPDATE_DATE = SYSDATE
===============
Index PO_LINES_N10 is on the column LAST_UPDATE_DATE , logically for such query , index should not have got used as that indexed column is not in select / where clause.
Also, why there is discrepancy between tkprof and trace generated for the same query .
So , I decided to INVISIBLE the index PO_LINES_N10 but still that index is getting accessed in the trace file .
I have also checked the below parameter , which is false so optimizer should not make use of invisible indexes during query execution.
SQL> show parameter invisible
NAME TYPE VALUE
----------- optimizer_use_invisible_indexes boolean FALSE
