Bad performance with graphic glitches running intensive OpenCL software
Under Yosemite Cinema 4D R16 (while R14 is works well) and Autocad for Mac 2015 (with all the previous releases) are affected by horizontal pixelated artifacts (not properly glitches by very near to be); and again iTunes library seems to be affected by horizontal portion of the library by the same glitch when you scroll down (it disappears after log out). Someone refers these issues to Vsync (that autodesk softwares make Off) while to me it seems clearly incompatibility drivers with Yosemite and last version of these softwares. My configuration is NVIDIA GeForce GTX 780M 4096 MB and mentioned softwares were fine under Mavericks and with the same Hardware...
There are currently two known operations that are seriously slower in update 10:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6635462
and
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6652116
(taken from the release notes).
You can disable the hardware pipeline to basically go back to the old situation as it was in update 7 if it is giving your problems. I wouldn't know why simple fill actions would be bogging it down though, it smells like something is done wrong in your app.

IMac crashes on startup or freezes with graphical glitches
Hi,
My early 2009 24" iMac suddenly crashed a few days ago, while browsing on the internet with no major app running. It did so with graphical glitches, like coloured dots. Since then, it would always shut down suddenly every time I restart. It shuts down right after the Apple logo and the wheel, once even reaching the user selection screen for a second, then shutting down before I could even move.
I started it in safe mode and ran all the checks, it says the volume is fine. When checking disk permissions, it did give me a few error messages but let me do the repairs. Weird thing is when I ran the disk permission verification again it showed me the same permission, as if they hadn't been repaired.
Now I backup everything and tried to reinstall OS X but to no avail, it kept doing the same thing.
So I formatted the disk, zeroed it out and reinstalled Mavericks. Same thing keeps happening, which seem to indicate some kind of hardware failure, right?
On one occasion it did start up but after a few seconds it froze, with heavy glitches (see picture attached - sorry it's upside down but it doesn't make a huge difference anyway!).
I upgraded the iMac with new RAM a year ago or so, and 2 years ago it had a hard drive failure, so I replaced the HD. Never had any problems in general, apart from when I had to replace the HD of course. It's always been very stable and well behaved.
Any idea what the problem could be? I'm not looking forward to having to fork out £1500 for a new one...http://www.apple.com/uk/legal/statutory-warranty/ may be worth reading before you visit Apple. I don't thibk you'd be the first to argue that an expensive, quality computer ought to last more than 5 years, albeit that say, mechanical hard drives inside might need replacing.

Bad performance with brandnew system
hello,
i set up a completely new win7-64bit based on a fresh osx (snow-leopard update) on a fresh harddisk....and i have very bad 3d performance with only 3 (!!) programs installed. i am working with autodesk 3ds max and autocad and both run very slow. my last system was win7-64bit, too, but running MUCH faster.
it must be a driver problem, but i dont know how to change the nvidia driver.
edit:
after having changed driver from directx 9 to open-gl performance is very fast.
please help.

In the following Re: Generic Sync: Object can not be deserilized / Multiple synchronization call you had mentioned that you are using MI 2.5 SP16 Client. For your information MI doesnt support Windows Mobile 5 OS on SP16 but only from SP18 does it support this OS. Have you tried upgrading the client to any of the SPs i had mentioned in the above thread and then checked the performance?

Problems with graphics card running windows on bootcamp..
I currently have Windows Vista 32 bit installed on my mac with bootcamp. The reason I have it installed is I want to run an MMO RPG (DDO) on my mac and it is only supported on windows.
However it will not allow me to play it as it says that no graphics device could be located (Game error 122 for those that play it)
My question is how I utilise the graphics card from the mac onto windows, as the VGA adaptor doesn't seem to be sufficient??
Either that or does anyone know of a way I can play DDO through MAC OS??
Any help much appreciated.
Thanks.Just tried what you recommended, but still to no avail..
What's confusing me is the following;
1)When checking system performance it tells me that my graphics are as follows
Graphics - Desktop performance for Windows Aero
Gaming Graphics - 3D Buisness and Gaming graphics performance.
2)http://svc.systemrequirementslab.com explains that I cannot run the game due to my graphics being inferior (I highly doubt this).
Minimum: 64 MB video card with Hardware T&L
(NVIDIA GeForce 2+ / ATI Radeon VE+)
You Have: Standard VGA Graphics Adapter
3)Just as the game is about to boot up it gives me the following message;
[Game Error 122] No suitable graphics device was found. Are you running through a rmeote session or a VM? If not, please check your video hardware capabilities.
I'm literally 30seconds away from throwing this macbook out the window, please can anyone help?!

Bad performance with Payables Open Interface Import
hello all
have a performance problem with the standard program Payables Open Interface Import, as this process is taking a long time to run.
could recommend some patch for this issue or a solution.
our application is 11.5.10.2 and Database 10g
now create a SR but to date we have not been sending the first plan of action
best regardsThere are many reasons this is a performance problem - search in MOS for "APXIIMPT performance" or "payables open interface import performance"
Your best bet is to work this thru an SR.
Have you traced the concurrent to determine where the bottleneck is ? Are statistics current ?

is_sender number(1) path 'c:element1Header/c:isSender/text()')
WHERE organization_id = 5 AND is_sender = 1 AND created >= sysdate-20 AND created <= sysdate+1;This query is fast as long as the results is small (<1000), but when the resultset grows bigger, the performance seems to decrease exponentially. The cause of this slowdown seems to be in the xmlqueries; commenting out the xmlqueries makes the query very fast again (in the order of a few seconds), even with a 15000+ resultset, while including the xmlqueries makes the query take many minutes.
Workaround I tried: using a rownum < 1000 works fairly well, but only if I don't use order by (which is required). order by forces the resultset to be full built regardless of the rownum limit. (this was done with a subquery orderby and a rownum on the superquery)
Other workaround i tried: Having the subquery only return the xml column, and doing the xmlqueries in the superquery. I couldn't get this to work, something about no longer having a key-preserved table.
Background info about the database: Oracle 11.2.0.3.0, binary xmltype column, with a xmlindex unstructured component on all paths in this query, and a structured component with secondary indexes on the paths used in the WHERE (created, organization_id and is_sender). Database has about 140k records total.
My question is, if anyone knows if this xmlquery bottleneck can be remedied somehow?
Addition: graph i made indicating the performance at different resultset sizes. Horizontal axis is size of resultset, vertical axis is time spent in seconds: http://i.imgur.com/F2tyg.pngJust count(*), nothing else in the select:

Bad performance with PreparedStatement
Hi,
I have a query that returns about 10.000 results on which I have to iterate.
The query is something like that :
SELECT col1,col2 FROM myTable INNER JOIN myTable2 using(id) WHERE time > TO_DATE('15/06/2009 16:28:00','DD/MM/YY HH24:MI:SS') AND time < TO_DATE('16/06/2009 2:35:00','DD/MM/YY HH24:MI:SS');
This query is ultra fast using a basic Statement, It iterate over all line of the cursor in less than 100ms.
The date parts of the query are generated using string concatenation.
Since it's a bad practice I have decided to use a PreparedStatement and so to change the query like that :
SELECT col1,col2 FROM myTable INNER JOIN myTable2 using(id) WHERE time > ? AND time < ?;
I bind the dates and I get exactly the same result, except the performance... Now it doesn't take 100ms... It take about 120000ms (2min)!!!?
The execution of the query is not the problem, the problem comes from the ResulSet.next() method that is much longer than before.
I precise that the exactly same values are used, the result is exactly the same.
I have tried different value for the fetch size but no big differences.
An idea?Sorry I have answer too fast. I have still performance issue when using the query :
SELECT col1,col2
FROM myTable
INNER JOIN myTable2 using(id)
WHERE time > TO_TIMESTAMP(?,'DD/MM/YY HH24:MI:SS.FF')
AND time < TO_TIMESTAMP(?,'DD/MM/YY HH24:MI:SS.FF')
PreparedStatement stmt = connection.prepareStatement(
SimpleDateFormat sf = new SimpleDateFormat("dd/MM/yy HH:mm:ss.SSS");
stmt.setString(1, sf.format(fromDate));
stmt.setString(2, sf.format(toDate));while the following query perfectly work :
SimpleDateFormat sf = new SimpleDateFormat("dd/MM/yy HH:mm:ss.SSS");
SELECT col1,col2
FROM myTable
INNER JOIN myTable2 using(id)
WHERE time > TO_TIMESTAMP('" + sf.format(fromDate) + "','DD/MM/YY HH24:MI:SS.FF')
AND time < TO_TIMESTAMP(('" + sf.format(toDate) + "','DD/MM/YY HH24:MI:SS.FF')Really bored of oracle products... -
Bad performance with non-cumulative key figures
Hi All,
I have a cube with 8 non cumulative key figures based on fiscper.
I am not sure how the performance for reporting with non-cumulatives can be improved.
Thanks
KarenPerformance of non cumulative cubes is dependant on the distance between the marker (date of the last compression) and the execution date.
For actual stock, the more you compress the better it is.

Bad performances with both catalyst and free driver
Hello,
With the catalyst driver 15.20 and Xorg 1.16 my graphic card(hd 7870) is not used at her maximum for example in kerbal space program i have beetween 45% and 88% Gpu load but only in place like oceans normaly it don't exceed 75%, i have the same issue in war thunder,star conflict,robocraft but with unigine benchmark's (valley and heaven) it is good. I dont think it is normal . The cpu isn't overloaded it is a i5 3570.
What can i do?
Last edited by remy18 (2015-06-02 17:57:59)Understood ewaller
I tried with another distribution (caculate linux) and i have the same issue so this is normal but i don't know why...

Freezing Mac Pro with graphics glitch?
Over the last 3 weeks I have been having my mac pro freeze up and become unresponsive to any input requiring a hard reboot from the power button. This freeze is associated with the open window having a line through it. It is a thin horizontal line that occurs in various sections of the page. I have noticed this occur occasionally without a concurrent freeze as well. It stays put as the widow scrolls and otherwise works properly. This line can also occur in the desktop. To me it sounds like a graphics card problem. Has anyone had similar experience?
Hi Gord,
first of: what graphics card is in your MP ?
If it is the ATI X1900, it might simply be that you have to clean the card and especially the fan from dust which has gathered over the time.
Shut down your MP, wait some minutes for it to cool down, open the side panel and look if the fan and/or the card itself is showing dust on and around it.
Clean the insides of your MP compressed canned air of all dust.
Reassemble your MP, boot up and see if it helps.

XML Publisher has bad performance with 10 concurrent users.
PeopleTools version:Tools: 8.48.09
OS/RDBMS Version*( required for Tools Forums): Oracle 10.2.0.4
Application type and version:
Description of the Problem/Question:
Customer currently testing a process which exposes XML publisher functionality via self service. The process calls an app engine which
generates an XML file, processed by XML Publisher, and then displayed in the browser window.
They have found that any more than ten or so users in our test environment (two app servers, one web server per app server) seems to slow
the process to a halt, even causing some requests to go unprocessed. The bottleneck seems to be at the web server (WebLogic) as the
database and app server performance metrics are very good, however PeopleSoft Ping suggests that the web server is having trouble.
production environment has 8 app servers, one web server per app server. Are there any configuration changes we can make to improve
the serving of PDFs from XML publisher output? Add more web servers per app server? WebLogic java VM heap settings?
WebLogic Server 8.1 SP5
Tuxedo: Version 8.1, 64-bit, Patch Level 192
Any other thoughts on performance degrade with XML Publisher with more than 10 users.
Are there any configuration changes we can make to improve the serving of PDFs from XML publisher output? Add more web servers per app server?
ThanksThere are currently two known operations that are seriously slower in update 10:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6635462
and
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6652116
(taken from the release notes).
You can disable the hardware pipeline to basically go back to the old situation as it was in update 7 if it is giving your problems. I wouldn't know why simple fill actions would be bogging it down though, it smells like something is done wrong in your app. -
Bad Performance with Oracle Lite 4.0.1
I have a table in Oracle Lite with 17000 records and 110 fields. A SELECT on this table needs 1 minute to finish. The same table and query only needs 1 second on Oracle 8i Server. MSDE also needs 1 second. All the relevant fields are indexed. Are there any parameters in Oracle Lite that we can tweak? Is there something else I'm forgetting?
Hi Shivek,
An excellent solution for this is provided in the metalink Note:455905.1.
Let me know if you have more questions.

Very Bad performance with high stress on Tempdb
Hello ,
below is the execution plan for a query rapidly increase the Tempdb and has very slow performance,
appreciate your suggestion to enhance this query (any data is available upon request)>Covering indexes will make a huge difference.
You can't simply "create-covering-index" yourself out from every performance jam.
Questions:
Is the query important enough to justify special consideration?
How many covering indexes?
What is the performance impact of the new covering indexes on other queries?

Overheating MacBook Pro 17" typically when high graphics requirements run
I have a refurb MBP 17" with 2GB RAM, (1GB from Crucial), 120GB drive, glossy display. Everything on this machine runs fine, but if I watch a TV show from iTunes, or play Halo, the graphics load makes the temperature of the machine go through the roof, well above 60 Celsius, sometime close to 70 C. The machine literally stops/freezes, and later continues. I use a small freeware program called SMC Fan Control, which allows me to increase the default fan speeds from 1000 RPM to 3000+ or more. Still no effect. Apple, what is going on with my machine? Anyone experiencing the same thing?
I am having similar problems on my four days old MacBook Pro 2.2GHz (Santa Rosa). It runs fine until I start a graphically intensive game, then it hangs with soundloops and sometimes with graphical glitches (so far I've been able to reproduce the crash in Call of Duty 2 and Redline, both running at maximum settings). In Redline the computer first froze for about ten seconds then resumed for a few seconds after which it finally crashed with corrupted textures showing.
I haven't been able to get any temperature readings just before the crashing but when running Warcraft III in window mode I've observed both CPU and GPU temperatures reaching 90°C before the fans spin up from 2000rpm to 6000rpm, cooling the above down to ~70°C. When the crashes occured the bottom casing was noticably hotter than when I was running Warcraft III.
My guess is that the GPU (or possibly some other chip) owerheats and shuts down to prevent permanent damage. This, if true, should not be happening on a fully functional computer.
I'm going to run the Hardware Test and also see if the crash can be reproduced in other games and if the same errors occur in windows (using boot camp). Then I guess I'll have to give apple supprt a call...
