SQL & PL/SQL :: Lexical Parameter Slow Down Query?
Feb 16, 2010
All my following query is running fine.
SELECT pd,
vr_date,
x.vr_no,
vr_sn,
cac,
ac,
nar,
[code]....
but problem is that when above query is used or oracle reports then and lexical parameter is used then i slows down more than 100 times
SELECT pd,
vr_date,
x.vr_no,
vr_sn,
cac,
[code]....
above query is copy of top query but differnce is that &P_Unt_Cls lexical parameter is used instead of and Unit in(29,34,35,36,37,38,44,45,60,70,71), I am unable to understand why it slow down query.

from pr_trans_dtl_v ptdv
where ptdv.trans_month=nvl(mtrans_month, ptdv.trans_month)
[code].......
see the highlighted row. can i use and ptdv.trans_type_row in &vtype instead of and ptdv.trans_type_row in ('R','A')
where the vtype is varchar2(100) and vtype:='(''R'',''A'')';

I'm using PreparedStatement to execute a query with some parameters. in sql developer, it just spends 12 seconds but in jdbc, it's around 140 seconds.
I disabled "_optim_peek_user_binds" parameter already but it didn't work. alter session set "_optim_peek_user_binds"=false;

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
AND SPL.SPLE_LEVEL <= '2' AND SPDA_ID NOT IN

I studied a document about lexical parameter in that it says "Lexical parameters are used to substitute multiple values at run time and are identified by a preceding '&'. Lexical s can consist of as little a one line where clause to an entire select statement"
Select * from emp, deptno &where.
and i know about substitution variables using & is this are same (lexical and substitution) or different.

EMP_DTL table is a subpartitioned table (Range partitioned by MonthID and subpartitioned by COUNTYR_CODE).
It has 40 million records. I just wanted to export 100,000 records altogeter from all partitions for testing purpose.
But when I ran the below expdp with QUERY , it was exporting 100,000 records from each subpartition of the table !!
expdp "'/ as sysdba'" tables = HRTB_CMBH.EMP_DTL dumpfile=EMP_DTL_BKP.dmp DIRECTORY= DATA_PMP1 QUERY=HRTB_CMBH.EMP_DTL:"where rownum < 100001" LOGFILE= exp-partitionedTable.log The log

I have developed a report using apex shared components (report query and report layout) along with BI Publisher for report printing in pdf format. the Report template is built using Template Builder for Word. I have configured my Apex4.1 env with BI Publisher 11. This report is working fine for hardecode ID ( like REQUEST_ID=10 ). to make report dynamic i have made following additions in the report
I have added where clause in report query as WHERE REQUEST_ID = :REQUEST_ID (:REQUEST_ID is the text field in my page).
Added a text field names :REQUEST_ID to get user input at run time.
Create a button and add Repot Query URL in its properties. When i run the report with some valid value in :REQUEST_ID text field i did not get expected result infect there is no record getting displayed in the PDF file. i think this is not the write way to do this but interestingly im not getting any error. how can i get this functionality in apex this way or the other ?

The issue is slow insertion in particular table(i.e A Table) it means insertion in all other tables(i.e B, C, D tables) in same schema is going properly but only when i am trying to insert in one particular table(i.e A table) in same schema it takes long time to complete insertion. Daily insertion is 6000 rows.
I have check all the details like Tablespace size, Analyzing of table, Analyzing of indexes and all. There is no any error alertlog file.

We have two database instances on the same server. One was left at 9.2.0.7 and one was upgraded to 10.2.0.3. Connecting externally (sqlplus '/as sysdba') to the 9.2.0.7 database is lightning fast. Connecting externally to the 10.2.0.3 database is very slow, comparatively speakiing. This is on an IBM AIX-5L (64-bit) machine. We are using "tnsnames".

I am migrating a oracle 9i database to 11g r3. I can only use imp. As the database is huge, I have split the exp dump by schemas. In my recent test, i have split the schema into 4 seperate threads to be imported into the new oracle11g database. The 4 thread of imp consist of almost similar sizes of schema (Eg thread 1 - Schema 1, 2 ,3. Thread 2 - Schema 4,5,6 etc)
All the dump files are in the same mount point. When i execute the import (4 threads) together, the total import timing is each thread is between 2.5 days to 3.5 days.
Then i proceed to try only 1 thread, only 2 hrs. So could this be a IO issue or oracle memory problem?
Specs
IBM AIX 6.1, 32GB RAM
Oracle
24GB AMM
Number of processes 500

we are busy updating one databasee from a windows platform 2003 oracle 10G to a linux and oracle 11r2
We exported/imported the data and it looks ok Explain plans look the same . but our heavy batches are twice slower than on the windows box ,the two top events are disk related, sequential and scattered reads there are 90% of the time of the batch job , i read some white paper and found that using ASM can be bad in some cases the same with the linux for this particular kind of scattered reads , i was just wondering if just changing the SGA to 10GB instead of 4GB to get more cache and speedup the things .

I am using :
Database : Oracle 8i
Application Server: Oracle AS 9i
Developer Suite : Oracle 6i(forms & reports)
I have created some character reports in oracle reports 6i.. when reports used run from my ERP(oracle 6i oriented) ... report usually took time to create on server. Sometimes my ERP used to hang up due to busy reports generation. And then we have to kill some processes to finally create charater reports on emergency basis.What is the valid reason for slow generation of report(character file )?

i have a nightly import ( about 20 tables ) and it takes up to 5 hours..we have one table of about 800,000 lines and the rest are between 1000 and 200,000 this is very slow when i monitor the import i see a very long amount of wait for the SQLnet from client ,
i run the import on the Database server itself .. if i check the current statement i see it's moving from one to one for instance i have
SELECT /*+ all_rows ordered */
"A".ROWID, 'REPORT', 'CONTRACT_LVL', 'SYS_C001329497'
FROM "REPORT"."CONTRACT_LVL" "A"
WHERE NOT (LENGTH (bonus_nat) <= 31)
then
SELECT /*+ all_rows ordered */
"A".ROWID, 'REPORT', 'CONTRACT_LVL', 'SYS_C001684584'
FROM "REPORT"."CONTRACT_LVL" "A"
WHERE NOT (LENGTH (outcome_cd) <= 1)
etc and it takes hours DB is on windows 2003 runnin oracle RDBMS 9.2.0.7 while the import screen show 185000 lines imported..I also see a lot of consistent gets for this sessions raising at that time..Would it be better to export import without statistics ?
I need also to mention that the dump file comes from a linux hosted Database don't think it will make the difference for a exp/imp.It's a peoplesoft Database there are a lot of tables more than 15000 and if i take the table mentioned above and i want to check its constraints it takes decade before toad can display them.I have seen that we have a incredible amount of constraints on those tables it might be the reason .
I just wonder if the system catalog needs to be tuned ? /* Update */ why but now the huge number of wait is no as "Library cache lock".

I am working on an SAP application migration project using Oracle 10.2.0.2 database. We are migrating the application from Windows to Solaris.
During the process we are facing problem with very slow insert operation on a particular table.The server's capacity is very good and so no resource bottleneck.
The table contains around 2,70,000 rows and inserting at around 100 rows per 10 seconds.
The table contains following data types.
SQL> desc SAPDATDB.CAF_GP_VALDEF;
Name Null? Type
----------------------------------------- -------- ----------------------------
VAL_UUID NOT NULL NVARCHAR2(34)
VAL_GUID NOT NULL NUMBER(10)

We have a function that is called in various other PL/SQL packages, and performance has always been very good. On 29th Sept we upgraded our db to 10.2.0.5.0 and since then, a package that calls the function has gone from ~4mins, to ~2.5hrs to run.
In PL/SQL Developer, a simple select that calls the function has gone from ~0.5secs to retrieve the first 100 rows, to ~12secs. I ran a profile of the main package, which highlighted the where the bottleneck was (a fetch from an explicit cursor). Running an explain plan on the cursor SQL doesn't really show up anything untoward.
However, I found that if I subtly changed the cursor SQL, (so that it did the same thing, but was written differently), it fixed the performance problems.
where ade_start_date between cpDate-cpDays and cpDate-1
/*and ade_start_date < cpDate
and ade_start_date >= (cpDate-cpDays)*/
From this, we thought that there may have been a bad cached execution plan which the change of code forced a recalculation of. However, about 2 hours later, the changed code ran slowly again. So a further subtle change was made, which fixed the issue again. Until this morning, when it was running slowly again.
This feels like it is CBO/stats related potentially, but is out of my area of knowledge unfortunately. We have our DBA investigating this, but there may be things I can test to narrow down the possibilities in the meantime.

I have big trouble with some Update query on Oracle 11G.I have a set of tables (5) of identical structures and a view that consists in an UNION ALL of the 5 tables.None of this table contains more than 20 000 rows.Let's call the view V_INTE_NE. Each of the basic table has a PRIMARY KEY defined on 3 NUMBERS(10,0) -> INTE_REF / NE_REF / INSTANCE.
Now, I get 6 rows in another table and I want to update my view from the data of this small table (let's call it SMALL). This table has the 3 columns INTE_REF / NE_REF / INSTANCE.
When I try to join the two tables :
SELECT * FROM T_INTE_NE T2
WHERE EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
I get the 6 lines in 0.037 seconds
When I try to update the view (I have an INSTEAD OF trigger that does nothing (just return for testing even without modifying anything), I execute the following query :
UPDATE T_INTE_NE T2
SET INTE_STATE = -11 WHERE
EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
The 6 rows are updated (at least TRIGGER is called) in 20 seconds.
However, in the execution plan, I can't see where Oracle takes time to achieve the query :
Plan hash value: 907176690
[code]....
Predicate Information (identified by operation id):
2 - access("T2"."INTE_REF"="T1"."INTEREF" AND "T2"."NE_REF"="T1"."NEREF" AND
"T2"."INTE_INST"="T1"."INSTANCE")
Note- dynamic sampling used for this statement (level=2)
Statistics
-----------------------------------------------------------
3 user calls
0 physical read total bytes
0 physical write total bytes
0 spare statistic 3
0 commit cleanout failures: cannot pin
[code]....
I get exactly the same execution plan (when autotrace is ON).Furthermore, if I try to do the same update on each of the basic tables, I get the rows updated instantaneously.
