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

My macbook pro is running very slow with some strange mouse and window movements. The trackpad is very unresponsive and when responding the cursor moves on its own and/or very erratically. When on safari the window suddenly zooms in or highlights words and looks them up via dictionary. I currently have a wireless mouse connected and I am still having the same problems.
I fee like I may have a virus or my laptop is perhaps being accessed remotely. All of the sharing options are unchecked.
HELP PLEASE
Very worried!!Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
after the chime press and hold down the OPTION key until the boot manager screen appears.
Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo). -
My MacBook Pro is running very slow with the wheel constantly spinning. Can anyone please help?!?!
My MacBook is running very slow and the wheel is constantly spinning. It's not just using the internet as it takes forever to start, open programs, etc. It is even taking me a long time to type in this question as the spinning wheel keeps coming up. Below is the EtreCheck. I would appreciate it if someone could please help me!

Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Startup and programs running very slow with Mavericks.
My late 2009 mac mini has been running very slow ever since the Mavericks install. I suspect it may be as simple as RAM capacity but I wanted to verify this assumption, as well as find out any other potential problems. I have gone ahead and run EtreCheck, here are the details of the output, thanks in advance:

MS-Access 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.I have seen the problem like this,too
can i have you -

Hi All
I am using Oracle 11g . My table contains 10-12 lac rows.Do not use the word lac: it is common in the Indian sub-continent but not known much outside of

1) what is the difference between a index on one column and an index of number of columns ( i.e composite index). The obvious answer of one contains only one column and the other contains more than one.
2) For what columns in a where clause should index be created ( single columns index or composite index ).Depends

Query occasionally causes table scans (db file sequential read)
Dear all,
we periodically issue a query on a huge table via an oracle job.
Whenever I invoke the query manually, the response time is good. When I start the periodic job, initially the response times are good as well. After some days, however, the query suddenly takes almost forever.
My vague guess is that for some reason the query suddenly changes the execution plan from using the primary key index to a full table scan (or huge index range scan). Maybe because of some problems with the primary key index (fragmentation? Other?).
- Could it be the case that the execution plan for a query changes (automatically) like this? For what reasons?
- Do you have any hints where to look for further information for analysis? (logs, special event types, ...)?
- Of course, the query was designed having involved indexes in mind. Also, I studied the execution plan and did not find hints for problematic table/range scans.
- It is not a lock contention problem
- When the query "takes forever", there is a "db file sequential read" event in v$session_event for the query with an ever increasing wait time. That's why I guess a (unreasonable) table scan is happening.
Some charachteristics of the table in question:
- ~ 30 Mio rows
- There are only insertions to the table, as well as updates on a single, indexed field. No deletes.
- There is an integer primary key field with an B-tree index.
Charachteristics of the query:
The main structure of the query is very simple and as follows: I select a range of about 100 rows via primary key "id", like:
Select * from TheTable where id>11222300 and id <= 11222400
There are several joins with rather small tables, which make the overall query more complicated.
However, the few (100) rows of the huge table in question should always be fetched using the primary key index, shouldn't it?
Please let me know if some relevant information about the problem is missing.
Thanks!
Best regards,

Dear all,
we periodically issue a query on a huge table via an oracle job.
Whenever I invoke the query manually, the response time is good. When I start the periodic job, initially the response times are good as well. After some days, however, the query suddenly takes almost forever.
My vague guess is that for some reason the query suddenly changes the execution plan from using the primary key index to a full table scan (or huge index range scan). Maybe because of some problems with the primary key index (fragmentation? Other?).
- Could it be the case that the execution plan for a query changes (automatically) like this? For what reasons?Yes possible, One reason is stats of the table has been changed i.e somebody issued dbms_stats. If you are worried about execution plan getting changed then two option 1) Lock the stats 2) Use hint in the query.
- Do you have any hints where to look for further information for analysis? (logs, special event types, ...)?Have a Ora-10053 trace enabled whenever query plan changes and analysis it.
- Of course, the query was designed having involved indexes in mind. Also, I studied the execution plan and did not find hints for problematic table/range scans.
- It is not a lock contention problem
- When the query "takes forever", there is a "db file sequential read" event in v$session_event for the query with an ever increasing wait time. That's why I guess a (unreasonable) table scan is happening.
If it db file sequential read then i see two things 1) It is doing index range scan(Not table full scan) or 2) It is scanning undo tablespaces.

Yes theoreitically it should practically we can only say by looking at run time explain plan(through 10053,10046 trace).
Please let me know if some relevant information about the problem is missing.
Thanks!
Best regards,
Nang.I am still not sure in which direction you are looking for solution.
Is your query performing bad once in a fortnight and next day it is all same again.
I suggest to
1) Check if the data is scanning undo tablespace. I see you mentioned there is lot of inserts, could be that Oracle would be scanning undo tablespace because of delayed clean out.
2) Check if that particular day the number of records are high compared to other day.
Or once it starts performing bad then for next couple of days there is no change in response time.
1) Check if explain plan has been changed?
And what action you take to bring back the response time to normal?

Very high log file sequential read and control file sequential read waits?
I have a 10.2.0.4 database and have 5 streams capture processes running to replicate data to another database. However I am seeing very high
log file sequential read and control file sequential read by the capture procesess. This is causing slowness in the database as the databass is wasting so much time on these wait events. From AWR report
Elapsed: 20.12 (mins)
DB Time: 67.04 (mins)
and From top 5 wait events
Event Waits Time(s) Avg Wait(ms) % Total Call Time Wait Class
CPU time 1,712 42.6
log file sequential read 99,909 683 7 17.0 System I/O
log file sync 49,702 426 9 10.6 Commit
control file sequential read262,625 384 1 9.6 System I/O
db file sequential read 41,528 378 9 9.4 User I/O
Oracle support hasn't been of much help, other than wasting my 10 days and telling me to try this and try that.
Do you have streams running in your environment, are you experiencing this wait. Have you done anything to resolve these waits..
ThanksWelcome to the forums.
There is insufficient information in what you have posted to know that your analysis of the situation is correct or anything about your Streams environment.
We don't know what you are replicating. Not size, not volume, not type of capture, not rules, etc.
We don't know the distance over which it is being replicated ... 10 ft. or 10 light years.
We don't have any AWR or ASH data to look at.
etc. etc. etc. If this is what you provided Oracle Support it is no wonder they were unable to help you.
To diagnose this problem, if one exists, requires someone on-site or with a very substantial body of data which you have not provided. The first step is to fill in the answers to all of the obvious first level questions. Then we will likely come back with a second level of questioning.
But when you do ... do not post here. Your questions are not "Database General" they are specific to Streams and there is a Streams forum specifically for them.
Thank you. -
2009 macbook running very slow with Yosemite?
After installing Yosemite there was a big change in performance for all actions on my computer. Start up, basic actions around the desktop and all applications are going considerably slower - slower than they ever have with my computer. I've changed a few of the settings, and that has helped, but it's still ridiculously slow. I haven't downloaded any MacCleaner app or anything. Can anyone help me with this?
Here's the results I got from EtreCheck:

Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

CS3 Still Very Slow with psd files
I'm still having terrible performance issues with CS3 and imported CMYK psd files containing spot colours. I have a 9MB psd file with two spot colours imported into a layer in Illustrator, with some illustrator line work on top. Just zooming in give me a 5 second screen redraw, everything is very sluggish and occasionally I get a crash. I still get these weird alert box saying "Generating Pixels" now and again when importing the psd files.
G5 Dual 2.0GHz, 2.5GB RAM, OSX 10.4.11, Illustrator 13.02, Photoshop 10.0.1.
I'm not having these issues on a different mac running CS2.I'm thinking it might be RAM, I have Photoshop and Illustrator open at the same time. I have around 100GB of scratch disk space.
But weirdly the slowness is not apparent using CS2. Things are just dead slow with a Photoshop file placed in Illustrator CS3. These files are only 30MB, but contain 3 spot channels + CMYK. Even with preview mode switched off, it's still very slow and I mean everything slows down.
There is a lot of disk activity going on, so maybe my hard disks on this 3 year old mac are just getting too long in the tooth.
What drives me nuts is I remember doing the same kind of work in Illustrator 8 on a G4 running System 9 and everything was MUCH faster.
Oh, and I'd better not mention how fast Freehand was for this kind of work... -
Sequence run VERY slow with SeqEdit.exe
Hi, My application sequence began to work very very slow while running under SeqEditor
Looking in the Windows Task Manager, it shows 50% constantly!!
Even steps like 'Lable' takes a longs time to execute.
Under Operator Interface it works just fine.
I have loaded some example sequence files from TestSTand/Example directory and they run just fine.
It seems that the problem is only with this specific file.
I can not use the SeqEditor as it is....PLEASE HELP!!!
Thanks
RafiSequence run fine with Operating Interface (as I pointed out in the first message).
Attached is the sequence file.
Thanks
Rafi

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. -

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.
