Query runs slower after INSERT

Hi All,
We have a java swing application that uses JDBC to interact with an Oracle database.
The user can display a list of data from one database table, then click a button which will insert a row into a different table using data from the highlighted row in the displayed list.
As long as the user does not click the "insert" button, [s]he can open and close the window displaying the list as many times as [s]he wants, and it runs very fast.
However, after the user clicks on the "insert" button, the query suddenly runs extremely slowly.
Also note that this behaviour only occurs on one particular database server:
Oracle9i Enterprise Edition Release 9.2.0.4.0
Sun-Fire-V210 with SunOS 5.9
The behaviour does not happen on other machines.
(None of the other machines have the same combination of database server and platform.)
Note that all the clients use the same JDK and JDBC driver.
Any suggestions on where we should look in order to discover the cause of this behaviour?
Thanks,
Avi.

Kamal,
In the trace file produced, the rowid pseudo-row has been added to my SQL query. Here is an excerpt:
(Note that the ALTER SESSION command was done via JDBC from our application.)
The following statements encountered a error during parse:
select rowid, FDU.DESK_USAGE_ROW_ID
from FLIGHTS F, FLIGHT_DESK_USAGE FDU
where ...
Error encountered: ORA-00918Error message for code ORA-00918 is "column ambiguously defined".
Since "rowid" is a pseudo column and since there are two tables involved in the query, obviously the unqualified "rowid" is ambiguous.
Naturally, I didn't put "rowid" in my original SELECT statment.
Is this added by JDBC, or by the Oracle optimizer, or what?
Thanks,
Avi.

Query running slow after 1000 rows in oracle

Hi.
I have one query which is fetching miln of rows.. the query runs very fast till 1000 to 1500 records after that it run very slow. Can you please help ,what could be the reason?
Thanks

I have one query which is fetching miln of rows.. Why are you fetching that many rows? What is your client code going to do with a million rows? And why do you expect this to be fast? A million rows worth of I/O has to be done by Oracle (that will likely be mostly from disk and not buffer cache). That million rows has to be copied from the Oracle's SGA to client memory. If your client is PL/SQL code, that will be copied into the PGA. If your client is external, then that copy has to happen across platform boundaries and the network too.
Then your code churns away on processing a million rows... doing what exactly? That "+what+" will need to be done once per row, for a million times. If it takes 10ms per row, that means almost 3h of client processing time.
Fetching that many rows..? Often a design and coding mistake. Always an exception to the rule. Will never be "fast".
And scalability and performance need to be addressed by re-examining the requirements, optimising the design that necessitates fetching that many rows, and using techniques such as parallel processing and thread safe code design.

Query running slow after upgrading

Hi,
We have one query that is running very slow in the 10.2.0.4 database after upgrading from 9.2.0.8 HP-UX B11.31. In 9.2.0.8 database it used to take 5 mins. But in the new 10.2.0.4 database it takes around 36 mins.The query is given below.

Thanks in advane.

Most likely, the index stats are not up-to-date, please double check.
h5. In 9i, FACT_NET_TRD_SLS_IDX3 is used to scan the fact.
Time dimension is used to filter out most records in fact table first, then join to Product dimension.
h5. In 10g, FACT_NET_TRD_SLS_IDX2 is used to scan the fact.
Time dimension "MERGE JOIN CARTESIAN" to Product dimension first to form a data set, and then use it to filter the fact table.
If the stats for FACT_NET_TRD_SLS_IDX2 let ORACLE believe that much less records will remain/survive after the join, 10g will use it.
It seems to me that cartesian join Time x Product is going to generate a much bigger data set than estimated, then the nested loop after that will take a long time to iterate through.
Why don't you partition your fact table BY RANGE(SLS_POSTD_DT_BE_ID) to make it simpler?

Query runs slower when using variables & faster when using hard coded value

Hi,
My query runs slower when i use variables but it runs faster when i use hard coded values. Why it is behaving like this ?
My query is in cursor definition in a procedure. Procedure runs faster when using hard coded valus and slower when using variables.
Can anybody help me out there?
Thanks in advance.

In the above procedure if i substitute the values with hard coded values i.e. AR_orgid = 123 & pcountry = 'Austria' then it runs faster.
Please let me know why it is so ?
Thanks in advance.

My macbook is running slow after upgrading to yosemite

Other's have posted similar experiences by when I ran etrecheck I didn't get a bunch of fails and yet my computer is extremely sluggish since moving from snow leopard to Yosemite. So much so, that I'm considering going back. Programs load slowly and switching between programs has a delayed response. Reminds me of the PC I had before I bought my macbook in 2008.
Any ideas on what might be causing the slow down?

Macbook Pro still running slow after reformat

So my Macbook pro, which is about 3-4 years old now, just started running slow after the latest update i did, whichever the latest one was. Possibly a security update or whatever it was. So i decided it was time to reformat and just clear out the stuff on my computer so i erased the HD and reinstalled Snow Leopard. After all that it still lags and is slow. Its slow on things like scrolling down a web page, or opening programs, or when i use expose, it isn't super smooth like it normally is.
My MBP has 4gb of ram and 2.2ghz. I have also tried to repair the disk permissions, but didnt seem to help drastically. Any suggestions?

Hi there,
Have you applied all updates? Using Software Update or manually? Checked for EFI and SMC versions?
Don't you have any clue from Console logs?
Repair as T posted and bring back news and info about your Graphic Card.
Good luck.

Why is my safari running slow after updating my mac?

My safari is running slow after completing a software update. I have cleared the cache. It did not help.

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Any change?
If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
Any change?
Quit and relaunch the browser. Any change?
Log out and log back in. Any change?
Enable Private Browsing in the Safari menu. Any change?
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If Parental Controls is active for any user, please turn it off and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

My computer is running slow after Yosemite install -but in the Mail program, when I open an email and then open the attachment -all is good -when I close the attachment the Mail program goes away, and I have to reopen it in my Dock -every time -been

My computer is running slow after Yosemite install -but in the Mail program, when I open an email and then open the attachment -all is good -when I close the attachment the Mail program goes away, and I have to reopen it in my Dock -every time.

I tried this, but no luck. I went to Previous System>Users. There is nothing inside the "Users" folder, so I hit a dead end.
I can find my new e-mails -- those that came in since I re-installed the system -- in my NEW system (which I did to see if I was correctly understanding the advice), by going to Users>Home>Library>Mail>POP account name>Inbox.
Let me add a new question: I am running PhotoShop C3. It opens OK, and I can use it, but when it opens I get this message: "One or more files for Adobe Application Support folder are missing. Please re-run the PhotoShop installer."
I don't like re-installing working programs if I can avoid it, because it always seems to lead to other issues. Any idea what files are missing, and where it/they might be in the Previous System folder?
thanks
Mike

I have an early 2008 macbook pro that is running slow after upgrading to lion. Is there anything I can do? this is what I have,Processor 2.4 GHz Intel Core 2 Duo, Memory 2 GB 667 MHz DDR2 SDRAM.

I have an early 2008 macbook pro that is running slow after upgrading to lion. Is there anything I can do? this is what I have,Processor 2.4 GHz Intel Core 2 Duo, Memory 2 GB 667 MHz DDR2 SDRAM.

First, back up all data immediately, as your boot drive may be failing.
Launch the usual set of applications you use when you notice the problem.
Step 1
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 page that opens.
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. What approximate values are shown for Reads in/sec and Writes out/sec?
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. 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.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

RUNNING SLOW AFTER OPENING KASPERSKY ON PARALLELS

RUNNING SLOW AFTER INSTALLING KASPERSKY ON PARALLELS

AV software is well-known for requiring large CPU and memory resources. You're running it in a virtual machine, which may have limitations on what CPU and RAM resources are allocated to it.
So, software that makes things run slowly makes things run extra slowly when a layer of virtualization is added.

Running slow after downloading a mandatory update

running slow after downloading an update!
I had zero complaints until today when I downloaded an update and restarted my machine.
Now It feels like I'm back in the PC world.
Any suggestions?

If it is Safari loading web pages slowly, I would suggest http://support.apple.com/kb/ts3230 or http://support.apple.com/kb/TS1594, one of these will surely help. If not, as previously suggested, more detail will greatly help.

Spotlight may be indexing your drive(s). Click the Spotlight icon at the right of your menubar; if it shows things being indexed, that's at least some of the reason.

Imac 11,2 running slower after installing software updates

I purchased my imac 11,2 Sept. 2010. I recently downloaded my software updates that included airport utility, itunes and canon printer software update. Since these downloads, the imac has been very slow. Does anybody have any suggestions why my imac runs slower after software updates and what can be done to get my imac back to previous speed.

isis24680,
Welcome to the Apple Discussions!
Did you run Disk Utility> Repair Permissions? Do you have your eMac in display-only sleep overnight, or use a utility such as OnyX, or otherwise ensure the Unix crom maintenenace scripts run? OS X 10.4.2 (in 7/05) included provision to force the maintenance scripts when sufficiently oberdue; it's possible you're seeing the Mac trying to catch up on a year-plus worth of maintenance.
Do you have anything showing in System Preferences> Others, especially anything that adds to the menu bar? You'll need to check that any add-on system utilities or background programs are updated to run properly under 10.4.6; a quick way to check is to Start Up in Safe Mode and see if performance returns to normal.
Open Applications> Utilities> Activity Monitor, show all tasks, and sort the list by CPU. Is their anything regularly showing up at more than say 15% of the CPU usage?

Video both in source window and edit window stops after just a few seconds. It also runs slow after a few seconds.

Video both in source window and edit window stops after just a few seconds. It also runs slow after a few seconds. I don't if the problem is the fact that it;'s a Vimeo down load. Any one got a suggestion as to why?
