Performance issue with Discoverer Viewer

Hi all

I'm working on Version 10.1.2.55.26 of Dicovere Viewer.
I have a report that opens quite quickly in Discoverer Plus but it takes much longer to open the same in Discoverer Viewer.
The faster the discoverer is also considerable slow compared to query data forms directly the database.

Where and how can I start optimizing to improve performance?
How can I check if the latest patches have been applied?
How to check if the Java version and if it is correct I'm supposed to be using?

Any help would be appreciated.

Thank you
VJ

Performance issue with a view
Hello
I HAVE 3 TABLES

T_FEB10
T_jAN10
T_dEC09

AND I HAVE A VISION

CREATE VIEW v1 AS
SELECT * FROM T_FEB10
Union of all the
SELECT * FROM T_JAN10
Union of all the
SELECT * FROM T_DEC09

WHEN I SPEAR
SELECT * FROM V1 WHERE ORDER_DATE = FEBRUARY 2, 10 '

The OPTIMIZER IS FULL SCAN THE FULL 3 TABLES (which is expected "but bad")
I WANT THAT IT ONLY SCAN THE TABLE T_FEB10

I THINK THAT THE SOLUTION TO THIS IS SET DISCOVER AND CREATE IT LIKE THIS.

CREATE VIEW v1 (DATE1, DATE2) HAVE
SELECT * FROM T_FEB10 WHERE ORDER_DATE BETWEEN DATE1 AND DATE2
Union of all the
SELECT * FROM T_JAN10 WHERE ORDER_DATE BETWEEN DATE1 AND DATE2
Union of all the
SELECT * FROM T_DEC09 WHERE ORDER_DATE BETWEEN DATE1 AND DATE2

ANY COMMENTS?

MY DB IS 8.1.7.4

Thank you very much
Partitioning is, of course, the recommended solution.

In the absence of partitioning (for example if you did not purchase the Option of partitioning or use Standard Edition), partitioned views is the implementation for Oracle 7.3

See http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:5955697076876

Remember: you will need to add CHECK constraints to your tables.

Performance issues with large number of nodes

I am creating an application to display graphics (large), for example:
But I ran into some performance issues, even for a relatively small number of nodes in the scene graph (+-2000 in the picture above). The graph is built, step by step, adding circles and paths to a StackPane. Circles and paths can be semi-transparant. For a small number of nodes, I get a solid 60 FPS, but this decreases over time to about 5 frames per second. As soon as I stop adding new nodes, the framerate shoot again up to 60 images per second. The framerate drop even when all the nodes are outside the viewport.
My questions are:
* Is Platform.runLater () call to 2000 times a minute too?
* This might just be a problem with my graphics card? (I have an Intel HD Graphics 3000)
* JavaFX pulse recorder says such things, are there meaningful information in that I'm missing?
PULSE: 1287 [163MS:321MS]
T14 (0 + 0ms): col of CSS
T14 (0 + 5ms): layout pass
T14 (6 + 152ms): waiting for the minutes of the previous
T14 (158 + 0ms): copy the State for graphic rendering
T12 (159 + 0ms): dirty opts calculated
T12: Path of the slow form for null
T12 (159 + 160ms): painted
T12 (319 + 2ms): Presentable.present
T12 (321 + 0ms): completed the presentation of painter
Counters:
Background image of the region used cached: 14
NGRegion renderBackgroundShape slow path: 1
Nodes displayed: 1839
Nodes visited during rendering: 1840

Basically, try some optimization of performance ranging from the simple to the complex. Each of the changes below may provide you with an increase in performance. Some will probably increase performance much more that others (depending on where is the real bottleneck). I would probably start by replace the paths to the lines and reduce the number of Platform.runLater calls (as adding nodes that fall within the viewport can be difficult only).

> The framerate drop even when all the nodes are outside the viewport.

Place the nodes in the graph, which fall inside the viewport.

> Is Platform.runLater () call to 2000 times a minute too?

Yes, there is no reason to call it more than 60 times a minute when the framerate of JavaFX is capped at 60 frames per second by default.

> This might just be a problem with my graphics card? (I have an Intel HD Graphics 3000)

Yes, it's a graphics system relatively low-end. But, look at the comment of developer below - your CPU and choice of graphic primitives can also affect rendering speed.

> Adding circles and the paths to a StackPane

You don't need a StackPane to this, a group is a container easier and probably better.

> may be semi-transparant

Remove transparency * may * cause acceleration.

You run may be:

https://JavaFX-JIRA.Kenai.com/browse/RT-20405 : improve the rendering of path performance

Maybe if you use lines rather than the paths, performance might improve.

A comment by a developer on this performance tweak application is:

«It is quite normal for applications that use arbitrary paths (if the node path objects, SVGPath, polyline, or polygon) because these paths are rendered in software.» As card circle, Ellipse, line and Rectangle very primitive forms easily to the operations that can be performed entirely on the GPU, which makes them essentially cheap. There is no need to compare the rendering of a complicated shape for rendering of simple primitives for this reason. »

----

Setting the cache indicators can help, but probably only if you animate nodes.

----

Present level of detail of your graph functionality so a chart with zoom out is not make as many nodes as a part of zoomed in.

----

You run any code important calculation on the JavaFX application thread that could stall it?

Can make you available a ftom so that others can reproduce your problems?

Performance issues with Photoshop CS6 64-Bit

Hello-
Issue at hand: in recent weeks, I noticed significant problems with performance since the last update PS CS6 using the Adobe Application Manager, from the unexpected shut downs to bring my computer to a crawl (literally, my cursor seems to crawl on my screens). I'm curious to know if anyone knows these issues, or if there is a solution I have not yet tried. Here is a list of actions that give rise to these performance issues - there are probably more that I have not experienced due to my frustration, or were not documented as occurring several times:
- Opening files - results by hanging processes, takes 3-10 seconds to solve
- Paste from the Clipboard - results by hanging processes, takes 3-10 seconds to solve
- Saving files - takes 3-10 seconds to open the dialog box, another 3 to 10 seconds to return to the normal window (saving an image PNG compressed)
- The eyedropper tool - will crash Photoshop on the desktop, or take 5 to 15 seconds to load
- Try to navigate any menu - Photoshop crash on the office or take 5 to 15 seconds to load
Attempts I took to solve this issue, which failed:
- Uninstalled all fonts I have added since the last update (it's a pain in the *, thanks to be glitch Windows Explorer)
- Uninstall and reinstall the application
- Edition 32-bit use
- Change process priority to above normal
- Confirm the process for all available cores of the processor affinity
- Change the configuration of the performance of Photoshop options
  - 61% of memory is available to Photoshop to use (8969 MB)
  - History States: 20; Cache levels: 6; Tile cache size: 1024K
  - Records of work: active on the production of SSD, ~ 10GB of available space
  - Dedicated graphics processor is selected (2 x nVidia cards in SLI)
System information:
- Intel i7 2600 K @ 3.40 GHz
- 16 GB of RAM Dual Channel DDR3 memory
- 2 x nVidia GeForce GTS 450 cards, 1 GB each
- Windows 7 Professional 64 bit
- Adobe Creative Cloud
This problem is cost me time that I work every day, and I'm about to start looking for alternatives and cancel my subscription if I can't get this resolved.

Have you tried to restore your preferences to set the parameters of performance return to their default values and restart Photoshop? http://blogs.Adobe.com/Crawlspace/2012/07/Photoshop-basic-troubleshooting-steps-to-fix-MOS t - issues.html #Preferences

Performance issue with the submodels
Hello
I'm working on submodels and my requirement needs only one main calling location several specific submodels (a location may have several own submodels, e.g.: US_subtemp1, US_subtemp2, US_subtemp3... in the same way to other locations).
I would like to know is there any performance issue associated with calls in the submodels and on how this decrease in performance can be minimized.

Kind regards
Arvind
Use of the submodels with components imported alongside repeated sections in the main template layout is not recommended when the number of repetitions is high and the size of the document is large. BI Publisher optimize the xsl transformation internally, but it is not applied to xsl inside models of void.
One of the extreme scenario is a main model set only a repeating section that matter a submodel of the header and the footer.
A body of the repeating section is defined in the subtemplate. In this scenario, there is no xsl optimization made and you can easily see some differences in performance.

As long as you don't need to repeat the layouts of submodels, you don't need to worry about this performance issue.

Thank you

Performance issue with an external HARD drive

Hi all

I wish you all a happy new year and good luck for 2008

I have a performance problem with a HARD drive: 3.5 inch USB 2.0 HDD with Alu - case. (320 GB of capacity)
The average copy files is about 470 KB/Sec.

When I connect the external HARD drive to my laptop (for any USB port), I have a ToolTip message: "this device can perform faster - this USB device can be faster if you connect it to a USB 2.0 port. I can assure you, my computer laptop USB USB 2.0 port.

I conneted my drive external HARD to both PC and I have the same ToolTip message: "this device can perform faster - this USB device can be faster if you connect it to a USB 2.0 port.

Is this problem known to you?
I think the problem is in the firmware of the external HARD drive.

+ Other ++ information: +.

+ OS: Windows XP Pro SP2 +.
+ USB port all tested are USB 2.0 +.
+ HARD drive divided on 4 logical drives.
+ Antivirus: Symantec. I had test with and without my antivirus. +
+ I have had this problem for 3 weeks and before that I had no problem. +

Thanks in advance & best regards,
Marouane

Hello

I got the same info after the connection of a digital camera.
The same message appears in the taskbar. I simply disbled this message;
In Device Manager, click the USB host controller, click the Advanced tab, and then check the box at the bottom of the window that says don't tell me about USB errors.

You must do this for each USB controller listed under USB in Device Manager, so that the error message no no matter which controller is used.

I goggled for this + this device can perform faster + and got many successes. It seems that this is not a hardware problem, but simply a problem of operating system software

That s all I can suggest

Performance issue with select only one option

Why meet autoSubmit = "true" for the component?
Are you doing any treatment/PPR on the same? This can cause the problem.

Performance issues with dynamic action (PL/SQL)

Hello!

I have problems of perfomance with dynamic action that is triggered on click of a button.
I have 5 drop-down lists to select the columns that users want filter, 5 drop-down lists to select an operation and 5 boxes of input values.
After that, it has a filter button that submits just the page based on the selected filters.
This part works fine, the data are filtered almost instantly.
After that, I have 3 selectors 3 boxes where users put the values they wish to update the filtered rows and column
There is a update button that calls the dynamic action (a procedure which is written below).
It should be in a straight line, the issue of performance might be the decoding section, because I need to cover the case when the user wants to set a null (@), and when it won't update the 3 columns, but less (he leaves ").
That's why P99_X_UC1 | ' = decode(' ||) P99_X_UV1 |', "«,» | P99_X_UC1 ||',''@'',null,'|| P99_X_UV1 |')
However, when I click finally on the button update, my browser freezes and nothing happens on the table.
Can anyone help me solve this problem and improve the speed of the update?
Kind regards
Ivan

Hello Ivan,.

I don't think that the decoding is relevant performance. Perhaps the update is suspended because another transaction has changes that are uncommitted to any of the affected rows or where clause is not quite selective and has a huge amount of documents to update.

In addition - and I may be wrong, because I only have a portion of your app - the code here looks like you've got a guy here huge sql injection vulnerability. Perhaps you should consider re - write your logic in the static sql. If this is not possible, you must make sure that the entered user contains only allowed values, for example by P99_X_On white list (i.e. to ensure that they contain only values known as 'is', ')<', ...),="" and="" by="" using="" dbms_assert.enquote_name/enquote_literal="" on="" the="" other="" p99_x_nnn="">

Potential performance issue with the mobile app

Hello
I'm working on a small mobile project to see how the view system and its performance.
To see what is happening with the objects, I tried the Profiler today and I was surprised to see that the Navigator object does not use view previous instances.
For example if I navigate between 2 displays the browser instead of using the 2 objects already created, it creates each time it's push() function is called.
Maybe there is something that I do not understand that it makes the behavior desired, if so can someone explain it to me please? If this isn't the case, then I'm worried about leaks memory after an intensive use of the views in the app.
I have to make it clear that I do not use any weird code that could disable the browser work properly, my app is less basic at this point and I'm also using weak references on each event listener to avoid problems of memory.

I didn't not try your code, but you could run this question: http://bugs.adobe.com/jira/browse/SDK-28396 , which was set after the beta version.

Performance issue with the Update statement

Oracle 10204

I have a problem related to updaing one performance table.
only 5000 lines should be updated.
Hir are some details on the tables/M.V concerned:

TABLE_NAME     LAST_ANALYZED          NUM_ROWS     SAMPLE_SIZE
PS_RF_INST_PROD     1/20/2010 1:14:22 AM     7194402          7194402

NAP_INTERNET     1/25/2010 11:47:02 AM     7053990          560777

I tried to run the update with two options:
1. with the plan than oracle choose.
2. with notes I added.
In both cases I he collapsed after more than an hour.

Can any one suggest how to speed it up?

Below are for the two option tkprof.

The problem in your update statement that is the query in your set clause is executed many times that there are lines in BL_TMP_INTRNT of 'intellectual property' in their column of term_desc. You mentioned there are about 5000, then the query joining NAP_INTERNET with PS_RF_ISNT_PROD is begun 5000 times.
The trick is to join only once, be updated using join views - provided that it is preserved - key or by using the merge statement.

Here is an example:

Performance issue with 2.5 "HDD + NAND MQ01ABD100H

Hello everyone.

I use this car for several days.
The problem is that player has lower estimate in the Windows system assessment tool then my old drive (WD500BEVT).

I run the benchmark in HDTune Pro and I get very bad result in n of the speed to the beginning of the trial. Overall performance is also much lower then I read in the comments.

Can you help me with this problem?
I am running Windows 7 64-bit teacher, all the drivers are installed, my laptop is A.c.e.r 5820TG (i5 - 450 M, 4 GB of DDR3 memory, ATi HD5650). Only a few days ago, is original and SP1.

Thans for all help.

I am attaching a link to a screenshot

Hello

According to the [page specifications MQ01ABDxxxH | http://storage.toshiba.eu/cms/en/hdd/solid_state_hybrid_drives/product_detail.jsp?productid=525], the HYBRID 2.5 INCH SATA DRIVE supports SATA III

For best performance, your laptop should also supports the SATA III HARD disk controller.
In the event that your laptop does not support SATA III, performance may be lower due to the limitation of HARD disk controller.

Performance issues with Vista on Satellite L40 - 14N

I just signed up to your forum, it's really nice, how it works.
I bought 3 months ago, a satellite L40-14N, with Vista Home Premium pre-installed, but I'm starting to get tired of the delays.
I also have a problem, always Walker I want to open some windows, such as control panel or my computer and all my icons on the desktop disappear after some time will be displayed again, but not the application open before (Panel configuration or my computer).

I wanted to ask all of you, what may be the problem, in fact I think to get rid of Vista and install XP, do you think it would be a good idea?
If so, what kind of xp (sp2, sp3, etc.)? And, what I would have in return when I install xp, as what drivers need me for my laptop works properly again?

Thank you very much... good day

Hello

He knows that the Vista operating system is in need of more resources as a Microsoft OS at the beginning of s.
I have a Vista on the L30 and I get a really slow performance.
In addition many services and processes running in the background of the operating system. It also decreases performance.
But all background processes are needed if you want to use all the features of notebooks such as the FN keys or buttons to Toshiba for example.

However, I've installed XP on the L30 without any additional driver for the FN keys, control buttons etc and it was amazing to see how fast the laptop can be.

So generally it s not a bad idea to install XP on the L40.
But note; If you want to install XP on the L40 you must install the Intel Matrix Storage Manager first. Without this driver SATA XP does not recognize the HARD drive.

Greetings

Windows Vista and especially performance issue with M/B AsRock P4i45GV R5.0

4 years ago, I bought AsRock P4i45GV-M/B 5.0 R, with Intel Pentium 4 processor with 2.40 GHz, 1 MB of L2 Cache.

I have installed Windows Vista, since Intel 82845 G onbaord graphics does not support Windows Vista, I havd to installed an add - in AGP card. I installed NVIDIA GeForce FX 5500 and I also tried NVIDIA GeForce FX 5200, but my system does not at all. It's really slow.

Is this due to add - on card AGP?

I installed 2 GB of RAM, which is the maximum amount of RAM my M/B can support.

I also tried with Windows 7, but it works worse than Windows Vista on my PC.

Please, help me to boost the performance of my system. I don't want to go back to Windows XP.

The problem may be because my M/B does not support Windows Vista and higher?

Rannvijay Kapoor

The processor and the graphcis card are old and not the fastest.

Buy a new basic system of AMD (Athlon II X 2/X 3, at least 2 GB of DDR3 RAM, a mainbaord with AMD 880 G chipset (integrated graphics card), you can use the old HARD disc), it is not too expensive, but gives you a boost huge performance.

Performance issue with multiple jumps of FCoE

At at - it implemented FCoE multihop on the new firmware 2.1? I moved my UCS lab he and storage performance stagnated. Here's what I have in my lab.

2 nexus 5500 s - used for LAN and FC switch

EMC CX4-120 - connected to the 5500 s Nexus 2

UCS 6120/FEX 2104 - Pre-FCoE to installation has been a port-channel 2 SAN ports in every tissue of the Nexus 5ks.

6 servers B200 M1

ESXi 5

I wired to the top a twinax addition on a fabric of interconnection to 5548 Nexus in FC fabric

I wired to the top a twinax addition on interconnection fabric Nexus 5548 FC fabric b B

Configured interfaces such as FCoE uplink in UCS

Placed the FCoE interfaces in the proper VSAN

A tissue at the same time, I have disabled port-channel SAN FC to force the vHBAs to connect to the uplink of FCoE. Didn't have any problems with this and vHBAs appeared in the table flogi to the couple of 5ks on the interface correct vfc.

Reloaded my ESXi (SAN boot) hosts and guests restarted very well using uplink of FCoE to Nexus 5ks.

When I turned on a virtual machine, it took more than 20 minutes for it to start and he was to the point where it was usable.

No drops or errors on the FCoE interfaces or the fabric of interconnections vfc and Nexus 5ks.

As soon as I have reactivated the CF port-channel SAN using 4 GB SFP modules and disable the performance of uplink FCoE was fine again.

I hope that it is something to do with the older hardware of the generation 1 6100 s and the IOM s 2100 and not a bug.

I have 2 other servers HP rack mount with CNAs Qlogic FCoE on the VMFS LUNS even without any problem.

Case ID: 624922297

The Nexus switches as well as technical support UCSM are attached.

Performance issue with the query when join OKS and tables of the IB

Found the solution

replaced by to_char (c.instance_id) = ki.object1_id1 AND
