Slow performance due to hitting a great view twice in a SELECT statement

This program is written in Oracle 9i reports but the problem is to do with the SQL, I decided to post the question here and non-Oracle reports. I am interested in finding the 'Pre' and 'All time' result values in this exercise. However, to achieve that, I am struck is large seen complex twice for all kidney patients. I was hoping maybe only hit from this point of view once. If there is no other way, maybe I could watch using a temporary table. I simplified (removed irrelevant columns) and using only 1 patient, so it might seem that my approach works well, but in reality the nature of the view (I have no control on the display), the performance takes a hit. Any help to improve this request would be greatly appreciated.

Scripts to create the tables and insert data:

create table PATIENT_TB (pat_id varchar2(4), start_date date);
insert into patient_tb (pat_id,start_date) values ('1001',to_date('10-MAR-14','DD-MON-RR'));

create table patient_result_vw (pat_id varchar2(4), renal_test_date date, renal_result_1 varchar2(1), renal_result_2 varchar2(1), renal_result_3 varchar2(1), renal_result_4 varchar2(1));
insert into patient_result_vw (pat_id,renal_test_date,renal_result_1,renal_result_2,renal_result_3,renal_result_4) values ('1001',to_date('01-MAR-14','DD-MON-RR'),'Y','N','N','N');
insert into patient_result_vw (pat_id,renal_test_date,renal_result_1,renal_result_2,renal_result_3,renal_result_4) values ('1001',to_date('01-MAY-14','DD-MON-RR'),'Y','Y','Y','N');

SQL:

The patient_result_vw view is used in the subquery 'pre' and the 'post' subquery and the reason why I have to do it because I need to isolate the values of "pre" before the Start Date. Also note that since I use Oracle reports, I am able to pass as a data link Start Date to the previous query. In any case, patient_tb response time is very fast.

select p.pat_id,
       pre_renal_result_1_flag, pre_renal_result_2_flag, pre_renal_result_3_flag, pre_renal_result_4_flag,
       post_renal_result_1_flag, post_renal_result_2_flag, post_renal_result_3_flag, post_renal_result_4_flag
from   patient_tb p,
       (
         select r.pat_id, max(r.renal_result_1) keep(dense_rank last order by r.renal_result_1 nulls first) pre_renal_result_1_flag,
                          max(r.renal_result_2) keep(dense_rank last order by r.renal_result_1 nulls first) pre_renal_result_2_flag,
                          max(r.renal_result_3) keep(dense_rank last order by r.renal_result_1 nulls first) pre_renal_result_3_flag,
                          max(r.renal_result_4) keep(dense_rank last order by r.renal_result_1 nulls first) pre_renal_result_4_flag
         from   patient_result_vw r
         where  renal_test_date < (select p2.start_date from patient_tb p2 where p2.pat_id = r.pat_id)
         group by r.pat_id, r.renal_test_date
       ) pre,
       (
         select r.pat_id, max(r.renal_result_1) keep(dense_rank last order by r.renal_result_1 nulls first) post_renal_result_1_flag,
                          max(r.renal_result_2) keep(dense_rank last order by r.renal_result_1 nulls first) post_renal_result_2_flag,
                          max(r.renal_result_3) keep(dense_rank last order by r.renal_result_1 nulls first) post_renal_result_3_flag,
                          max(r.renal_result_4) keep(dense_rank last order by r.renal_result_1 nulls first) post_renal_result_4_flag
         from   patient_result_vw r
         group by r.pat_id
       ) post
where p.pat_id = pre.pat_id 
and   p.pat_id = post.pat_id ;

... From a results point of view, there is a priority as to which the result should be picked up (for pre and Post). I'm supposed to take the highest value (being the highest, then N and then NULL), but before the Start Date. The results of 'Post' (in reality, it's all time results), there is no Date of departure concerned. Once again, the results of the post, I will pick up the highest score (the highest, can N and then white).

...

You want plain old simple MAX for it.

MAX (a) KEEP (DENSE_RANK LAST ORDER BY ter)

is something different: it is the value of a that is related to the highest value of b. Only a tie for the most high b is the value of a same considered.

I have tried with and without the trailing slash and the final semicolon... no work...
When I run SQL Developer, it creates the view.
Can someone tell me why?

Thanks in advance,

Gus,

It seems that you have a completely empty line in your CREATE VIEW statement. This will cause the statement fails. If please remove this line and try again.

Extremely slow performance with Radeon HD 7870

Hello
I use a number of Adobe programs on my new 64 bit system of Windows 8, with 16 GB of ram, a processor Intel Core 2.67 ghz i5 and AMD Radeon HD 7870 2 gig. All programs (including After Effects and Illustrator) work very well with the exception of Photoshop CS6 64 bits, which is extremely slow performance with GPU to use enabled in my preferences (Photoshop selects by default). If I disable the graphic processor use, this slowdown faints. If I change the Basic Design Mode, there might be a slightly detectable improvement during Normal and advanced, but it is still horribly slow. The refresh rate seems to be only a few frames per second. Everything is slow: brushes, zoom, panoramic, as well.
I tried changing the settings I've seen suggested elsewhere: I went 2 level of Cache, history says 10 and the size of the tile to 128 k. No effect. Photoshop is currently the default using 60 percent of available ram. Efficiency has remained 100% overall of all my tests. In addition, this slow performance touched me from the moment that I installed Photoshop; It didn't arise after previous good performance. The problem exists regardless of the size or the number of documents that I opened. Performance is always terrible, even when I create a new blank canvas of 500 x 500 pixels and try a simple task like drawing with a brush.
Photoshop is perfectly up to date, and so are my graphic drivers (Catalyst version 13.1). Any help would be greatly appreciated; yet performance is so bad in Photoshop it is unusable, graphic acceleration activated. Thanks in advance for the answer.

I use Catalyst 12.8 pilots at the moment and have a Windows 7 system and have a remote access utility called Radmin installed, but I don't know if seeing that Microsoft based Render driver is provided on Windows 8. It seems that this could be the key, as the basic OpenGL implementation of Microsoft is made all in software. If somehow driver Microsoft took control and you don't get really the GPU acceleration, then that would surely make things really slow.

Rafaello, you have updated drivers... You can post your top of your system information again?

Have you tried a full, complete deletion ATI driver and reinstall from for example, 13.2 beta? Here is the removal of ATI tool:

Very slow performance with Windows 7 on i7 Quad

I bought my wife a Lenovo E530 i7 quad with screen 1600 x 900 and running Win 7 in September 2012. Previously, she had an Asus Core 2 Duo also with Win 7. The laptop is used to picture (scanning, editing, cataloging) work, family, the navigation and email history.

The E530 was desperately slow at the beginning. Not better, not faster than the Asus. Performance seems to vary from slow to excruciatingly slow.

Features include:

-very slow to open programs

-slow to react to the choice of menus and clicks

-slow to react to the touchpad

-scrolling is not smooth, vibrates, much worse than Asus

-often distorts the sound and video, audio stutters

-IE9 make often video has properly - green band across the bottom with the rest of the colors shifted upward - change the video quality will fix it sometimes

-very slow internet response compared to the other machines on the same network of navigation.

However, startup speed seems to be OK.

I spent weeks (months?) through the forums, verification of updates, deletion and restoration of various programs and drivers looking for driver clashes. I tried the clean boot with only Windows drivers and various other combinations, and it made no difference.

For a long time wifi would be max 54 Mbps but somewhere through the process he begins to operate at up to 300Mbps.

Nothing seems to stand out in reports on health of the system and the event viewer. Windows experience scores seem to be everything I expected from my older i7.

Resources and performance monitor reports a problem with the hard drive:

The average disk queue length = Max 16 = 106

%Idle = 0

Disk read/s Ave = 0.093 Max = 3

Disk sec/Transfer Ave = 0,067 Max = 1

Disk s/write = 0.022 Ave

Even when the computer runs slower the CPU usage, and memory usage is not mounted and ceiling ever.

SFC report any breach of integrity.

FixIt MS - slow performance does not detect any problems.

The disk check is not a problem any.

It's so frustrating that my wife threatens to throw it in the trash and buy a Mac (the horrors :-)).

Any ideas on what I might have missed or what I should look at?

Thank you

Ken

Wish I had a 128 GB SSD. I suppose you see a serious helping hand to the performance of the system.

Please do not forget to mark the answer.

It is possible, and it depends on what simultaneous programs are underway.

iPad Pro 9.7 "slow performance on wifi

Hi all - looking for Apple's brain trust land on this one.

I recently bought the new Pro peripheral 9.7 "iPad (wifi and cellular) and have noticed a lot of slow performance when you use it on a wifi network.

I also have an iPhone 6s so decided to compare the two head to head, both on the same wifi network. Going to the same sites, YouTube, download my diary, it's okay - 6 bulbs just with speed so that the iPad Pro chugs and takes significantly longer to download exactly the same content. The old iPad Air that I used to use never had this problem. The problem doesn't seem to be the same thing with WiFi cell, just the one. It connects to the wifi network is fast blisteringply so I exclude the network being the issue. I was wondering if anyone else has this problem.

I must say im very disappointed iPad pro account $ 1300 or so I paid for it. I am strongly considering to return.

Details: iPad Pro 9.7 "128 gb Wifi + 4 G Gold

running iOS 9.3.1

All advice appreciated.

Mike

Have you tried a hard reset of your iPad by pressing the sleep/wake and Home buttons simultaneously until your iPad goes to black and restarts with the Apple logo and then release the buttons?

Good luck

Satellite A205-S5864 - stop itself and the slow performance

I'm new to this forum, so help me out anyway you can.

I noticed that my Toshiba laptop showing odd behavior lately. She recently began to stop himself suddenly without warning. We arrived at the point where it is a regular occurrence. I don't know what it is, if the computer is starting to show it's age, or a hardware problem, etc.. I hope that's not die because this computer begins to happen over two years. The computer knows that he was arrested not because I get the message that this was not decommissioned and how I want to start in.
I also noticed that, even though I have a core 2 processor, the computer takes awhile to start. I don't know how to improve the performance, because I regularly clean the registry and trash. I have norton 360 along with spyware blaster.

any input would be appreciated. I will post more details that are necessary.

Hello

I m not A205 owner but on my computer Toshiba laptop, I got the same problem it stops and the reason was a higher internal CPU temperature. So I ve looked in the forum and founded an interesting article on the cleaning of a Toshiba laptop. That's why you need compressed air and you can clean without disassembly.
Check this box!

Your slow performance it of difficult to say something on this issue, but in most cases it s advisable to reinstall Windows.
In my opinion the Norton antivirus slows performance a little so I m using the software tool free AntiVir.

I have improved my Qosmio G30 126 at 4 GB of Ram, SSD 64 HDD as windows7 boot partition and 500 GB 7200 64cache HARD drive as drive HARD secondary but I have a very slow HARD drive performance when working in windows7, but when I work on a virtual machine Windows XP, the disk HARD perforemance is fine.

I've upgraded all drivers from toshiba.com for windows7 ultimate 32-bit drivers including drivers from the chipset intel but my problem is not solved. I also check all other performance issues and its OK.

The same problem exsists on my old HARD drive on Windows Vista Ultimate 32-bit and Windows 7 ultimate 32 bit.

I used HD tune software to check my HARD drive it accelerates gives about 100bps in windows 7 for my SSD and it gives 285mbps (this is the actual read speed) in the machine virtual Windows XP and the actual speed is significantly different.

Please tell me what to do because I suffer from my laptop very slow and spend a lot of mony on it without more.

Hello

To be honest it is really hard to tell why you have slow HARD drive performance but especially it s associated with a large number of programs they are running in the background. How many processes are started after Windows starts?

Also, the antivirus program may affect the performance of the computer. I would recommend using the AntiVir freeware tool and the Windows Firewall. That's enough if keep you Windows up-to-date and use a new Internet browser.

Also check the other discussions of the forum on the slow performance. You can find a lot of useful tips to improve performance. For example:
-Defragment HARD drive
-Disable the startup programs you don't need
-Uninstall unnecessary programs
-Run the CCleaner tool to remove old registry keys

Satellite A200-1TW - slow performance even with a SSD HARD drive

I replaced the HARD drive of 160 GB for a Seagate Momentus XT 500 GB and even a Samsun 830 256 GB SSD, but my HARD drive performance is very slow.

How can I increase the performance of my HARD drive?

I have 4 GB of RAM and I am using Windows 7 Home.

What do you mean exactly by the slow HARD drive performance.

As far as I know the laptop supports a SATA I (1.5 Gbit/s / 150 MB/s) the HARD disk controller.
Even if you would upgrade the laptop with a SSD drive that supports 3 Gbps, the controller could slow performance.

Satellite A60 (PSA60E): slow performance

Hello
I have the laptop above. the performance of this laptop is terrible, when I start an application it takes up to 10 seconds before opening the windows of the app.
specs. family BIOS 1.90, win XP Edition version, 192 MB internal. It is a normal standard a60 with none of the exceptional items.
Someone at - it a trick to speed up performance.

Hello

As you know there are several reasons why the laptop is running slowly.
Before any if multiple processes are running in the background for the operating system is running slowly. You should check the background processes in the Task Manager and try disabling no important processes.
Then it is possible that a virus will decrease the performance of your laptop.
In this case, you must update the antivirus application.
The antivirus application that runs on your laptop and monitor background processes may also be responsible for slow performance.

But the best way is to install fresh OS. The laptop runs always faster with the installation of claire. Alternatively, you can upgrade the memory to increase the performance of your laptop.

Satellite T110-11U: WLan connection dropped and very slow performance

Hi people,

I use a Satellite T110-11U running windows 7 Home premium.

After having initially was very satisfied with its use, it now becomes more and more frustrating to use with wifi, with connections dropped and very slow performance.

I have updated the BIOS and think I have updated all drivers wirelss, but could be the problem. It seems that wireless, software of management is at fault because the networks are detected, but not clinging.

Any suggestion or tips to try will help save my sanity!

Thanks for your help.

John

> have updated the BIOS and think I have updated all drivers wirelss, but could be the problem.
If you need to make sure that you use the latest WLan driver.
The driver can be downloaded here:
http://APS2.toshiba-tro.de/WLAN/

The laptop uses the Realtek RTL8191SE of WLan card.
Please also reset the settings of the Wlan router. I had a lot of problems with my WLan and after the reset of the router, performance problems disappeared.

High CPU use/Slow Performance after you install the updates of Windows

I run Vista Business 32-bit.

After you install many Windows updates in the last few days, I've known very slow performance after the system worked for a while. Resource monitor shows 70-100% CPU usage, even when you run all the apps (that I know of). This makes everyhting grind to a halt, same trip that the mouse jerky movements. I ran several complete system with McAfee anti virus scans and not found problems (using the latest software). The detail showed the so-called ", PID4 NT kernel and system" using 18% avialable CPU capacity, but this process is not always shown to use much more capacity when the slow performance occurs. Nothing else don't use much capacity CPU, I see.

More recently, the capacity of the CPU became crazy, jumping from zero to 100% usage in a back a suite oscillation. When I shut down and restart, performance improves, but erodes little by little over time.

Is this a sign of a virus, or is it a problem with the recent Windows updates or some kind of conflict with my software such as McAfee? How do I tell me what to do? Anyone else have this problem with the recent Windows updates?

Help! Thank you!!

McAfee applications (and Norton) are known for not not upgrade (or uninstalling) itself.

1. download the McAfee Consumer Product Removal, save it to your desktop tool: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

2. close all open applications (that is, anything with an icon on the taskbar).

3. now run this triple McAfee fix: http://service.mcafee.com/FAQDocument.aspx?id=TS100507

NOTE: Step #2 McAfee fix run the removal tool, you have already downloaded in my step #1 above.

4 IMPORTANT! => After the reinstallation of the McAfee application (step #3 of the McAfee fix), manually & repeatedly updated the McAfee application, until you get a prompt "no update more".

5. open Internet Explorer (only) to http://support.microsoft.com/kb/923737 & run the difficulty.

6. OPTIONAL: For good measure, pen also Internet Explore (only) to http://support.microsoft.com/kb/971058 & race that secure it in DEFAULT and modes and AGGRESSIVE. [1]

7 restart a last time & test.

~~~~~~~~~~~~~~~~~~~~~~~~
[1] full Disclosure: the difficulty operating in AGGRESSIVE mode will remove your update history but not the list of installed updates.

Too many software - slow performance

I too installed software and had slowed performance. Just added 2 GB of RAM, and it helped. Took the computer to Best Buy for analysis and they gave me a list of about 110 programs of software that are installed. However, when I go into Add/Remove Programs, controls, some of the software on the list of Best Buy isn't on my Add/Remove list. Where can I find the software that is not in the Add/Remove Control Panel programs, but is listed as the software on my computer? Can I assume that it will be in the Explorer of Windows Defender - software? Is there a 'General' rule which should absolutely stay and not be deleted? Will I guess that if there "Dell", "Embarq" (my ISP), "Microsoft", "Windows" - I should exercise caution and not delete?

There are a lot of software listed below, but I hope someone can tell me to remove one or more of them. Help! Can what software I remove to help my performance? Thank you!

Dumprep.exe causes slow performance

Anyone have any suggestions on how to fix Dumprep.exe causing the slow performance?

My XP is slow recently.

Does anyone have any suggestions?
Thanks in advance for your suggestions

It's the dump reporting tool and it runs when some program/process causes an error in the system. Therefore, you should know what that the root of the error and fix it. Since you told us nothing about your computer and its recent history, here is general information on troubleshooting a slow computer:

Some reasons for the slow pace of the computer:

1. computer has not been maintained - http://www.elephantboycomputers.com/page2.html#Maintenance

2. the computer is infected with the malware - http://www.elephantboycomputers.com/page2.html#Removing_Malware

3. the disk is too full. Remove useless stuff, uninstall unused programs. Do not forget to save!
http://www.elephantboycomputers.com/page2.html#Backing_Up

4. flaky third party software. Toolbars and modules are particularly guilty in this area. Uninstall toolbars (Google, Yahoo, ISP brand, etc) and look at what modules are in use in your browser (s).

5. computer has too many unnecessary programs/processes running in the background. Manage your Startup:

For XP - How to troubleshoot using the Msconfig in Windows XP utility - http://support.microsoft.com/?id=310560
The free Autoruns program is very useful for managing your Startup - http://www.microsoft.com/technet/sysinternals/default.mspx

For Vista/Windows7 - Start Orb > Search box > type: msconfig and when it appears in the results area above, right-click and choose 'run as administrator '. Autoruns is also very useful.

6. the user runs an inflated/invasive such as Norton and McAfee antivirus program. Replace it with a better program. I recommend NOD32 (commercial) or Avast (free). Avira is also good, but the free version has an unpleasant reminder screen (Google for instructions on how to disable it). The user can also run several real-time antivirus/firewall/security programs.

7. the user has installed new programs that are processor and/or memory-intensive (Photoshop, AutoCAD, Mathmatica or similar) and does not have the power of the equipment.

8 drive fails and is in PIO Mode (IDE only - not applicable for disks SATA drives). It's very much slow (like being in 1985). See Hans-Georg Michna here information -http://winhlp.com/?q=node/10

If the hotfix registry PIO only 'glue' (or you have a SATA drive), the drive is probably faulty and needs to be tested.

Slow performance when multiple connected clients, WSM 6.0 x 64

Slow performance when multiple connected clients, WSM 6.0 x 64

Hello

When users logs on, its quick and pleasant.

However, when many connects, it slows down everything.

The linked site server has basic 16 total, 24 GB of RAM, and 8 x 300 GB 10 k in RAID10 discs.

I see the server is loading rather low, he got 4 x 1 Gbit/s in the lacp to a switch of concert team, then all switches have 1gig uplink.

The server use never more than about 10 GB of RAM, this could be the problem and how to get the server to use more RAM?

Total cpu load stay about 1 to 2%, network, all about 1500Mbps picks

There is only one 25 GB os image file, and it slows down when all about 30-40 users open a session.

This affect MaxSystemCacheMBytes? If I for example 1% or 200 MB, might lower it being 'forced' to spend more RAM?
