Sometimes the query is slow.

ORACLE: 10.1.0.5
The same query takes very different time to end.
I've traced two different runs (10046,level 12).
The explain plan is the same.

Is there anybody can help me?
How can I tune the db/system/application to have the same execution time?

The explain plan of the both runs is the same.

Do you always identify that many rows (approx. 100k) with the statement or can it be significantly different (less or more)?
Yes, I always identify approx 100K rows.
You're obviously using CURSOR_SHARING=SIMILAR or FORCE and therefore share the execution plan if the number of in-list items is the same.
Did both runs use the identical predicates?
Yes, we are using CURSOR_SHARING=SIMILAR. The test script uses always the same predicates

Why is the query so slow?

Hi,
I've got a query running fast (3 sec.)
If I try to execute it on test enviroment, it takes about 2 minutes (!)
I see in both enviroments the explain plan is the same and so are the indexes used. I've also tried to rebuild the indexes and the tables that looked quite fragmented in test, but the result is always the same. Could it be that our test enviroment is slower and with lower performances? What else could I check? (Oracle Vers. is 8.1.7)
Thanks!

Query very slow!

I have Oracle 9i and SUN OS 5.8
I have a Java application that have a query to the Customer table. This table has 2.000.000 of records and I have to show its in pages (20 record each page)
The user query for example the Customer that the Last Name begin with O. Then the application shows the first 20 records with this condition and order by Name.
Then I have to create 2 querys
1)
SELECT id_customer,Name
FROM Customers
WHERE Name like 'O%'
ORDER BY id_customer
But when I proved this query in TOAD it take long to do it (the time consuming was 15 minutes)
I have the index in the NAME field!!
Besides, if the user want to go to the second page the query is executed again. (The java programmers said me that)
What is your recommendation to optimize it????? I need to obtain the information in
few seconds.
2)
SELECT count(*) FROM Customers WHERE NAME like 'O%'
I have to do this query because I need to known How many pages (20 records) I need to show.
Example with 5000 records I have to have 250 pages.
But when I proved this query in TOAD it take long to do it (the time consuming was 30 seconds)
What is your recommendation to optimize it????? I need to obtain the information in
few seconds.
Thanks in advance!

This appears to be a dulpicate of a post in the Query very slow! forum.
Claudio, since the same folks tend to read both forums, it is generally preferred that you post questions in only one forum. That way, multiple people don't spend time writing generally equivalent replies.

We have 3 node RAC. When we test onw query it slow by 40% in one instance and always physical reads are hapenning in that instance.
Below are the details. All the parameters are same. Users compains some times the query is slow.

You can also check global cache statistics. Run this before and after your query :
select name, value from v$mystat s, v$statname n where s.statistic#=n.statistic# and name like '%blocks received';

Query is slow

SELECT SUM(A.NO_MONTH_CONSUMPTION),SUM(A.BASE_CONSUMPTION),SUM(A.CURRENT_DOC_AMT),SUM(A.CUR_TAX),SUM(B.CURRENT_DOC_AMT)
FROM VW_x A,(SELECT CURRENT_DOC_AMT,DOC_NO
FROM VW_y B
WHERE NVL(B.VOID_STATUS,0)=0 AND B.TR_TYPE_CODE='SW' AND B.BPREF_NO=:B4 AND B.SERVICE_CODE=:B3 AND B.BIZ_PART_CODE=:B2 AND B.CONS_CODE=:B1 ) B
WHERE A.BPREF_NO=:B4 AND A.SERVICE_CODE=:B3 AND A.BIZ_PART_CODE=:B2 AND A.CONS_CODE=:B1 AND A.BILL_MONTH >:B5 AND NVL(A.VOID_STATUS,0)=0 AND NVL(A.AVG_IND,0)= 2 AND A.DOC_NO=B.DOC_NO(+)
the above view "VW_x" has around 40 million records from two tables and avg_ind column has only 0 and 2 values. I created a functional index on both table something like create index on x1 nvl(avg,0)

Hi sorry i was out of office for a while please check the execution plan for my query.
Below query i am calling in a procedure passing the parameters
While i execute the query separatly it works fine but the same thing when i call in procedure and the procedure has loop which goes and check around 400,000 records thats where i get the problem
select sum(a.no_month_consumption),sum(a.base_consumption),sum(a.current_doc_amt),sum(a.cur_tax),sum(b.current_doc_amt

SSRS 2008 R2 is extremely slow. The query runs in less than a second in the dataset designer but if you try to view the report it takes over 10 minutes. I have read this is a bug in SSRS 2008 R2. We installed the most recent patches and service packs.

SSRS 2008 R2 is extremely slow. The query runs in less than a second in the dataset designer but if you try to view the report it takes over 10 minutes. I have read this is a bug in SSRS 2008 R2. We installed the most recent patches and
service packs. Nothing we've done so far has fixed it and I see that I'm not the only person with this problem. However I don't see any answers either.

Hi Kim Sharp,
According to your description that when you view the report it is extremely slow in SSRS 2008 R2 but it is very fast when execute the query in dataset designer, right?
I have tested on my local environment and can‘t reproduce the issue. Obviously, it is the performance issue, rendering performance can be affected by a combination of factors that include hardware, number of concurrent users accessing reports, the amount
of data in a report, design of the report, and output format. If you have parameters in your report which contains many values in the list, the bad performance as you mentioned is an known issue on 2008 R2 and already have the hotfix:
http://support.microsoft.com/kb/2276203
Any issue after applying the update, I recommend you that submit a feedback at https://connect.microsoft.com/SQLServer/
If you don’t have, you can do some action to improve the performance when designing the report. Because how you create and update reports affects how fast the report renders.
Actually, the Report Server ExecutionLog2 view contains reports performance data. You could make use of below query to see where the report processing time is being spent:
After you determine whether the delay time is in data retrieval, report processing, or report rendering:
use ReportServer
SELECT TOP 10 ReportPath,parameters,
TimeDataRetrieval + TimeProcessing + TimeRendering as [total time],
TimeDataRetrieval, TimeProcessing, TimeRendering,
ByteCount, [RowCount],Source, AdditionalInfo
FROM ExecutionLog2
ORDER BY Timestart DESC
Use below methods to help troubleshoot issues according to the above query result :
Troubleshooting Reports: Report Performance
Besides this, you could also follow these articles for more information about this issue:

Hi,
the plan isn't showing any problem (the cost isn't high) so it's not possible to use it to troublehshoot the query. Please provide more information: 4-digit Oracle version, and depending on the version, either SQL real-time monitor report or dbms_xplan output with rowsource stats (option "iostats last" after running your sql with ALTER SESSION SET STATISTICS_LEVEL = ALL).
Also, when reporting a performance problem it would be wise to avoid expressions like "very, very slow" replacing them with something more useful like "my query is taking 2.5 hours to retrieve 30k rows".
Best regards,

Sql query extremely slow in the new linux environment , memory issues?

We just migrated to a new dev environment in Linux REDHAT5, and now the query is very slow, and I used the TOAD to run the query, it took like 700 msecond to finish, however from any server connection, the sql query takes hours to finish.
I checked toad monitor, it said need to increase db_buffer_cache and shared pool too small.
Also three red alert from toad is:
1. Library Cache get hit ratio: Dynamic or unsharable sql
2. Chained fetch ratio: PCT free too low for a table
3. parse to execute ratio: HIgh parse to execute ratio.
App team said it ran real quick in the old AIX system, however I ran it in old system, and monitored in the toad, it gave me all same 5 red alerts in old system, and it did provide query results a lot quicker though.

If you do not find a solution in the iPod nano (6th generation) - User Guide, suggest that you call AppleCare if still under warranty or take a trip to your local Apple Store or AASP.

Sql query runs slower from the application

Hi,
We are using oracle 9ias on AIX box.The jdk version used: 1.3.1 . From the j2ee application when we perfom a search, the sql query takes for ever to return the results. I know that we are waiting on the database because I can see the query working when I look at TOAD.But if i run the same query on the database server itself, it returns the results in less than a sec. Could you guys throw some light on how we could troubleshoot this problem. Thanks.

When the results have to travel over the network, it is slow, and when they don't, it is fast.
That is what you are saying, correct?
So your approach should be to not bring so much data over the network. Don't select columns you don't need, and don't select rows you don't need.

Query execution slow for the first time...

I am new to Oracle sql.
I have a query whose performance is very slow for the first time, but on subsequent executions its fast. When executed for the first time it is taking around 45 seconds and on subsequent executions, 600 milliseconds.
Is there a specific reason for this to happen. I am calling this query from my java code using a prepare statement.

Are the differences in queries solely in the where clause? If so can you parameterize the query and use bind variables instead so the only difference from one query to the next is the values of the bind variables? Using bind variables in your queries will enable the parser to reuse the already parsed queries even when the bound values differ.
Also there may be other optimizations that can be made to either your query or the tables that it is querying against to improve your performance. To be able to improve your queries performance you need to understand how it's accessing the database.
See Rob's thread on query optimization [When your query takes too long |http://forums.oracle.com/forums/thread.jspa?threadID=501834&start=0&tstart=0] for a primer on optimizing your query.

Query running slow in one node

Hi All,
We are running 4-node Oracle 10g RAC (linux 64-bit). The query is running fast in one node, but the same query is running very slow in the other node. And sometimes, we see pin S wait on X wait event in top 5 events.
Has anyone faced this kind of situation before ?
Thanks,
Kumar

Hi,
Execute your query on node where query is running very slow. Get SID and execute query above to see what is event of waiting.
exec dbms_application_info.set_client_info('@sw2')
-- file sw2.sql
col event format     a25 heading "Wait Event" trunc
col state format     a15 heading "Wait State" trunc
col siw    format   99999 heading "Waited So|Far (ms)"
col wt     format 9999999 heading "Time Waited|(ms)"
select event,
       state,
       seconds_in_wait siw,
       wait_time wt
from   v$session_wait
where sid = &sid
order by event;
exec dbms_application_info.set_client_info('@sw1');
-- file sw1.sql
set linesize 30000
set pagesize 200
col sid      format    9999 heading "SID"
col username format     a10 heading "USERNAME"
col osuser   format     a20 heading "OSUSER"
col event    format     a25 heading "Wait Event" trunc
col state    format     a15 heading "Wait State" trunc
col siw      format   99999 heading "Waited So|Far (ms)"
col wt       format 9999999 heading "Time Waited|(ms)"
col sw1      format 9999999 heading "File"
col sw2      format 9999999 heading "Block"
col Objeto   format a50
select sw.event,
       sw.p1,
       sw.p2,
       sw.p3,
       sw.state,
       s.sid,
       S.osuser,
       s.username,
       nvl(s.program, s.module),
       sw.seconds_in_wait siw,
       sw.wait_time wt
from gv$session_wait sw,
       gv$session s
WHERE sw.sid = s.sid
   and sw.EVENT NOT LIKE 'SQL%'
   and username is not NULL
   and s.inst_id = sw.inst_id

I just downloaded the latest version of firefox (5.0). Can I delete all the older versions that are still on my drive? 2) When I call up some web sites sometimes the web site comes up 3 or 4 times...how do I stop this from happening?

I just downloaded the latest version of firefox (5.0). Can I delete all the older versions that are still on my drive?
When I call up some web sites sometimes the web site comes up 3 or 4 times...how do I stop this from happening? For example if I click on a link the exact same link comes up 3 or 4 times and I have to manually delete all of them but one.

Do you organise your email into separate folders, or do you just let it accumulate in the Inbox?
I would strongly advise you not to let it sit in the Inbox.
When you see this happening, try right-click on the affected folder, select '''Properties''' then '''Repair Folder'''.
Large folders (actually, a folder in Thunderbird is stored as a file, so it is sensitive to file size limits set by the underlying file system) can be problematic. This is one reason not to let messages collect in one folder. I use Thunderbird's Archive folders so that accumulated mails over several years can happily coexist because they are effectively stored in many small folders. No single mail store folder then exceeds the 2GB or 4GB sizes that have been known to stress the OS. I appreciate that current builds of Thunderbird and a modern 64-bit OS should be able to cope, but practically I find it slows down when given huge files, so I err towards a pragmatic solution; a large number of not very big files.
Archives are searchable, and a Saved Search folder can give you a virtual composite folder allowing access to the entire Archive.

Error executing the Query after deploying and executing the application in WLS 6.1 SP3

Hi,
We are trying to run a application by deploying a war file on Web Logic Server
6.1 SP3. After deploying and at the time of execution of the application, the
server console displays this error message
java.sql.SQLException: ORA-00600: internal error code, arguments: [ttcgcshnd-1],
[0], [], [], [], [], [], []
While debugging thru the application we found that this error comes at the time
of execution of the query thru the Statement.executeQuery method of java.sql.Statement
class.
This same application when deployed on Web Logic Server 8.1 runs perfectly, without
any hitches.
Please, provide me the solution to this asap.

Look for sometime around November. No exact date.

Thanks Eric,
you know what I'm going to ask next right?
Any ideas when SP4 comes out?
Cheers,

The next version of Apache that we will support will be 2.0.42/2.0.43
and
the module for that will be included in the next Service Pack for6.1(SP4)
and 7.0(SP2).
The problem with Apache 2 is that when a new release comes out a newmodule
needs to be compiled. Most of the time. For 2.0.42/2.0.43 this is notthe
case.

I'm trying to set this up (initially just apache in front of a single
WLS
server but ultimately I want to put it in front of a cluster).
I've installed Apache 2.0.40.
I've copied the mod_wl_20.so file into the apache modules folder.
I've edited the httpd.conf file and added the line:
LoadModule weblogic_module modules/mod_wl_20.so
When I run apache -t to check the configuration I get the following:
C:\Program Files\Apache Group\Apache2\bin>apache -t
Syntax error on line 173 of C:/Program Files/Apache
Group/Apache2/conf/httpd.conf:
Cannot load C:/Program Files/Apache Group/Apache2/modules/mod_wl_20.sointo
server: The specified procedure could not be found.
So what's going on here?
Looking at previous postings it sounds like there's an issue with
versions
of apache after 2.0.39 but I can't find a download for that version.Also,
it sounded like the issues were for WLS 7, not 6.1. Can this work
with
2.0.40 or am I wasting my time?
If I get the mod_wl_20.so from dev2dev I get the "incompatible plugin"
message that has been mentioned in this group already.
Any suggestions appreciated,
-Dominic

Sometimes the query is slow.
