Oracle Query runs very slow filling table

I have used Java Studio Creator 2 with Sun Java System Application Server Platform Edition 8.1_02 (build b06-fcs) in the past. I created a simple oracle query to populate a table and displaying about 560 rows in a table via a web browser. This runs excellent.
Now, I use Netbeans 6, along with Sun Java System Application Server 9.1 (build b58g-fcs), I populate a table using the same query as before and it takes quite a long time to fill the table. Actually, the browser keeps asking if I want to stop the script about 6 times. If I keep saying yes, it eventually completes.
I'm using an Oracle 9i database and have tried different drivers from Oracle with the same results.
Any idea why the difference in filling the table or how to correct this? Thanks!
Please note: I have this same question posted in the Java.net forums but it's not been answered so far, I hope this isn't crossposting and I get yelled at!

for NetBeans questions I suggest posting your question in the [email protected] For more information:

Oracle query running very slow

Hi,
We've MS-Access application which was pointing to UDB. Now we migrated it to point Oracle DB 9.2. After migration some of the query is running very slow.
These queries used to take less than 30 seconds in UDB now taking more than 5 Minutes in Oracle.
some more obeservation :
(1) Some of the queries using "HAVING" clause without any aggregate function. When I moved this condition to "WHERE" clause, performance improved a lot.
But problem is that I can't suggest this solution to "USERS". They are creating query using "query wizard" in MS-Access and they started creating noise on this.
(2) I tested same MDB in two different PCs and same query is returning records in 4 seconds in one system, is taking more than 10 minutes in other system.
Since I'm new to MS-Access, I don't know what other information I need to provide here.
Please help me out.

Hi Experts,
I have just installed SAP GUI 710 but when i open a query in analyzer it runs very slow and if the variables are set for more than 6 months it just sits there and finally times out. It takes at least 5 minutes to open the query if it opens at all. Can you please advise me on how to resolve this issue??
Thanks, point will be awarded.

Here's the verbatim response I gave yesterday to another user also posting his SQL and asking the same question.. why is it slow?
Who says it is not already running as fast as possible?
In order to solve a problem, you need to know the problem. Stating something like 'a query is slow and should be faster' is stating an opinion - it is not describing a problem that can be resolved.
My suggestion is to turn a complex problem, into a bunch of smaller and simpler problems. If you suspect that the query could be faster, pull it apart. Test each step/component of the query in isolation. E.g. start with a single table and progressively add joins to determine what the CBO does with each additional join, what you're asking Oracle to do ito processing, and not only checking that the CBO does not make obvious errors, but that what you're asking via SQL is the best approach to get to the answer.

Oracle Reports running very slow

The same Oracle reports, which used to take 15 seconds to complete, now takes about 4 minutes to complete. Any ideas? Thank you.

Thank you for your reply. Could you be more specific about network problem? We've changed our web application server and reports server settings recently. What could cause network problems? <HR></BLOCKQUOTE>
Well, I would suggest that you got to be very clear with the query. Most of the report peformace is based on the query.
1. Make sure that query is fine and note down the time it takes.
2. If first step is clear and if you are happy with the output that is process time, then you can think about tuning the report.
( You may want skip this step)
3. If that does not work you can investigate
what kind of array it uses and network speed and other thinks. I am not really familior with these set up.
Good luck with it..

VO Query runs very slow in jdev, quickly in Toad/SQL Plus

Hi,
I am trying to create a search application using JSF with ADF BC. I have a VO based on a SQL query, which joins two tables. The search criteria is referenced using bind parameters in the VO.
In Toad, SQL Plus, and SQL Developer, I can run my VO query and the results return quickly, within a couple of seconds. An Explain Plan indicates that all indexes are being correctly used. However, when I try to run my search form (exact same query) in jdev, it executes extremely slowly - almost 5 minutes before a result set is returned. My VO query is below.
select oea.order_yr,
oea.order_type,
oea.order_key,
oea.max_rev,
oeo.profit_center_id,
oeo.contract_total_price,
oeo.complexity
from oe_admin oea,
oe_order oeo
where oea.admin_id = oeo.admin_id
and oeo.profit_center_id = :ProfitCenter
and oea.order_yr = nvl(:OYear, oea.order_yr)
and oea.order_type = nvl(:OType, oea.order_type)
I've been messing with this for several days and I'm out of ideas. Does anyone have any suggestions?

The question is not whether the query uses a viewLink but rather do you have any other views that are linked to this view - if you do have such views you might want to check the setting for whether children are retrieved as well.
Also run ADF BC in debug mode to see the exact query that is being sent to the server and check out the explain plan for that one.

Query running very slow for 2LIS_13_VDKON Extractor.

Dear Experts
Having no Standard InfoCube to accommodate the data from 2LIS_13_VDKON Extractor, I've created an InfoCube having the Standard DSO inbetween. The Data Flow is as below:
2LIS_13_VDKON -> ZSD_DS17 (which is a copy of BCT DSO 0SD_O06) -> ZSD_C17 ---> ZSD_M02 (MultiProvider)
We went live last week and there are only 1252377 records in the InfoCube at the moment in Production. The BEx Query designed on top of the MultiProvider runs by default for the last 3 Months (Variable created) initially and the User will be able to look up only the last 13 Months (another Variable created) of data at any given point in time.
The User doesn't want any Selection Parameters on this Report and that's how it is created.
The problem now is.. this 'Margin on Agreed Cost' Report taking about 3 Minutes and 5 Seconds to run.
I have RSRV on the InfoCube and everything seems to be ok, tried Aggregates (though I understand that this number of records wouldn't need one to be created) and have also tried Query Cache today but no good.
Is there anything that I might have overlooked when designing the InfoCube and the BEx Query? Attached are the screenshots of the InfoCube, MultiProvider and the BEx Query for your reference.
Any suggestions are very much appreciated.
Thanks in advance for your time.

Hi Anshu
Thanks for your time.
The link you've sent was very useful indeed.
I followed instructions from your link and below are the statistics 4 days after this Cube went into Production:
As you could see, the InfoCube design is very fine.
We have noticed that the Report runs within a few seconds when it is run by 0BILL_DATE in Selection Parameters. Therefore, we are trying to buy the End User to have some Selection Parameters so that the performance of the Report will improve.
I have already created Aggregates for this Cube but in vain!
Can anyone please send me the Screenshots of the InfoCube Design which captures all the fields of 2LIS_13_VDKON Extractor?
Thanks,
Chandu

Query running very slow with db file sequential read waits which all indexes would be recommended

My query is doing lot of db file sequential reads I want to create few indexes and extended stats please help me with your suggestions.
Can anybody suggest I am unable to paste my query here -don't know why it's not getting pasted--is it not permitted ?
thank you.

The simplest way to find it out is using Oracle Enterprise Manager. Just locate the SQL ID for the SQL and run "SQL tuning advisor". This will exactly pinpoint where do you need to create indexes etc. Another option is manually running explain plan for the SQL and finding out which predicate is causing full scans with high i/o

Query can run in Oracle 10g but very slow in 11g

Hi,
We've just migrated to Oracle 11g and we noticed that some of our view are very slow (it takes seconds in 10g and takes 30 minutes in 11g), and the tables are using the local table.
Do any of you face the same issue?
This is our query:
SELECT
A.wellbore
,a.depth center
,d.MD maxbc
,d.XDELT xbc
,d.YDELT ybc
,e.MD minac
,e.XDELT xac
,e.YDELT yac
from
table_A d,table_A e, table_B a
where a.wellbore = d.WELLBORE (+)
and a.wellbore = e.WELLBORE(+)
and d.MD = (select max(MD) from table_A b where b.MD < a.depth and
d.wellBORE = b.wellBORE)
and e.md = (select min(md) from table_A c where c.MD > a.depth and
e.wellBORE = c.wellBORE);

Thanks I will move to the correct one..
Rafi,
Build the Indexes and it is still slow. I am querying from a view from another database, which is in 10g instances.

Oracle 10gr2 Master/detail form running very slow when you navigate to the detail record.

Hi All, I have a master detail form, running in webserver, when I navigate to the detail block, the form start buffering and buttering for about 2 min. There is a trigger when-new-record instance that is firing when you navigate to a new record : The select part of this stament is taken a long time to execute. I modified this in toad and what used to take 25 seconds to run is taken less than a second now, but the slowness still persists in the form.
for rec in (select wrrh_col
                  wpbh_col_lvd,
                   wpbh_col_doc_no
      from wh_col,
           wkpl_col,
           wh_col
     where wrrh_col_no = :block.wreh_wrrh_col_no
       and wrrh_col_no = wreh_wrrh_col_no
         and wrrh_col_no = wpbh_col_no
       and wrrh_col_proj    = wpbh_col_proj
       and wrrh_proj_no     = wpbh_proj_no) loop
   if fun_name(rec.wpbh_col_lvd) = 'Y' then
    do something,
   end if;
end loop;
The select staement that used to run for 23 seconds is running in less than one second, but the form is still running very slow when I navigate to the detail record.
Please advise.
Thanks.

Thanks Andrea for your prompt response, the problem is the select statement and like I stated, I tuned the select statement in toad and what normally takes 23 secs is taking less than 1 sec to run. If I comment out the call to the function, it is still slow. The select stament will returned null and it will still be slow. When I comment out the for loop, it run very fast. I dont know what else to do than tuned the select statement.

Mac book pro is running very slow. is there a way to do a disc cleanup?

mac book pro is running very slow. is there a way to do a disc cleanup?

First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the system log for messages that may indicate a hardware fault. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.
