Oracle in dual processor (urgent)

i have using oracle in dual processor in my server, but some of my report (5 user using these report) run very slowly. i have 2 Gb memory. i have already checked the index and i did the export import to make sure there's not chain row. but still this report run very slowly. do i have to defragment my server? because yesterday. i did long processing that took 58 hours.
i do not know the reason. please help me to solve this as it is very urgent
Thanks in advance

Oracle on dual-/multi- processor server

I have a question regarding Oracle on dual (or multi) processor servers. I have purchased 2 copies of the standard edition. I installed it on the server with 2 processors.
My question is whether or not there is something different in the installation for multi processors.
Another question would be if it is possible to install the database on a dual processor, if you only have a single copy of the license.

The licenses are acquired by CPU or by users and you acquired the license for only 1 processor you must not install it on a server with 2 processors. Your enterprise can have legal problems if that situation occurs.

Oracle Database on Dual-Processor Servers

Hello All,
I am contemplating on transferring my two instances of oracle 10g rel1 rdbms to a dual processor server from a single processor one.
What advantages will I gain? Is it really worth it?
I will appreciage any ideas, suggestions, comments, etc.
Thank you and with warm regards

Hi Justin,
Thank you very much for your reply.
Acutally, the instances running on my database server our production and development databases. The server would still host the two instances. BTW, my server is a Linux box (RHEL ES 4.0) with 3GB RAM running an intel XEON 3.0Ghz CPU (HP-Compaq ML-350).
I have Grid Control installed in a Windows 2003 where I manage the two instances and when I monitor the databases, I always get alerts that the CPU and memory utlizations are very high, in the high 90s (%).
Last night, I was informed that our server room will be made as location of an additional database server that will host databases for HR,Procurement,Inventory and Logistics and we will be the DBA for that. User base would be around 40 simultaneus online users at a any given time plus or minus 5 users. Total possible users will be around 100. Operation is from 7am to 6 pm, weekdays.
For this server, we have proposed dual processor (intel XEON) and 4GB RAM. Would this be enough to meet our incoming requirements?
Thank you and regards,
Mike

Urgent : UI refresh problem on dual processor or hyper threaded machine

Hello,
I am developing an applet that displays a set of tabs to the user. Each tab contains JLists.
When user selects from any of the JList(s), all lists are updated to reflect what is still available for selection. Number of elements in the list can be as large as few hundred thousands. This all works fine on single processor machine.
However, when running same on dual processor or Intel hyperthreaded processor, lists are not updated correctly. What I meant is that, for example, if a list originally has 100 thousands elements in it, then when I select an element from it, list is updated with available elements.Assume there are only 2 thousand elements available after above selection.Everything is fine so far, but when I de-select my selection, list is suppose to be updated again with original 100 thousands elements displayed again. The real problem is list indeed gets updated properly but few elements from list are not visible on the screen. However, If I minimize the browser(as it is an applet) and restore it again, all elemnets within the list are displayed correctly. Any help will be highly appreciated.

When your JLIst refresh occurs, the items are loaded into the JList from some other Object right? Nt knowing more about your code, I can't say exactly what that would be.Yes, you are right. Let me explain in breif about the architecture of the code.
I have a class,say CatPanel, that extends from JPanel and has BorderLayout with JList (wrapped in JScrollPane) in the center.
The main GUI class controls all such CatPanels.So, when the list is to be updated, GUI class invokes a method from CatPanel with Vector of elements to be inserted as an argument. Elements are inserted using setListData method of the JList.
If I'm right, the this might explain the behavior you are seeing. In a single processor environment, the data >is not cahced and therefore everything is fine. When you go to the dual-processor machine, the threads >have their own caches and are not always in sync. When you mimize the window and restoer it, this could >trigger a resync of the cache.Is there a way to trigger such synchronization?
One thing I'm not sure about is, when you return to the 'main' list, do you still see the selected sublist or >the main list with some elements missing? When a list is updated as a result of de-selection, few elements from start of the list are not visible.
I can see all other elements by using ScrollBar. So, if there are some selections that belong to the begining portion of the list, then selected sublist is not visible.
Let me explain with following example. Assume that with current selection, I have 100 elements in the list and all of them are visible on the screen. Now as a result of de-selection, suppose now the list should contain 200 elements rather than 100 elements. So, what happens in this case is that if first 50 elements are not visible in the list then I can see blank space corresponding to first 50 elements at the start of the list followed by remaining elements. I tried overloading paint method of an element that is actually inserted into the list, but still the result is same.

"Inconsistent cursor cache. Out of range cursor" error on dual processor multi thread

I have a C++ with Pro*C++ COM object running on a Win2000 OS on
a dual processor Middleware. The program is being called by a
service in a multi threaded way. An oracle error like ORA-2103
and SQL-02103 will be generated after running the program. We've
tried putting mutex on every SQL statement in Pro*C and it works
but the systems became very very slow. We concluded that the
error might be cause by a collision of threads accessing the
same Table or different tables having foreign constraints. This
is so because the error keeps coming from a statement accessing
Table A and following errors comes from a Table B having a
foreign key on Table A.
Our only solution now is to put Mutex on Statements accessing
same tables or tables with foreign constraints but this will
make our system run very very slow. I dont know if the problem
is in our Oracle Database because we already upgraded our system
from 8.1.6 to 8.1.7. The wierd thing on this is that the system
is running smoothly without oracle errors on a SINGLE PROCESSOR
Middleware. Hope you can give me any insights on this problem.

Any process to follow if we keep the dual processor

Hi all of u,
I am using Oracle 10g. My question is, In the Windows 2003 Prof. single processor i installed the Oracle 10g server. After that we ordered the dual processor for this server system. Now What to do this, shall i deinstall the oracle 10g and install again in this machine or it will run as usual.
Any process to follow if we keep the dual processor.
Oracle 10g Version 10.2.0.1.0
OS: Microsoft Windows 2003 Prof.

Thank u for al u r reply. I understood, but i want to know is any changes made to any parameter in that database folder to improve the performance after keeping multiprocessor to the server system.
I mean to say that in the books it has given that " PARALLEL PROCESSING CAN HELP IMPROVE PERFORMANCE IN SITUATIONS WHERE LARGE AMOUNTS OF DATA NEED TO EXAMINED OR PROCESSED, SUCH AS SCANNING LARGE TABLES, JOINING LARGE TABLES CREATING LARGE INDEXES AND SCANNING PARTITIONED INDEXES.
PARALLEL PROCESSING REQUIRES MORE PROCESSING MEMORY, AND I/O RESOURCES THAN SERIAL PROCESSING.
So any parameters to add to improve the performance of the database when we install multiprocessor in server system.
Thank u..
Ravi

I have a late 2008 Macbook Pro, I am trying to run MW3 but it will not work without crashing a few minuets into the game. The general specs on my computer are a dual processor 2.53 ghz. 4 gb ram and a NVIDIA geforce 9400 (9600 is the alternate card)

Things to note:
I have been unable to update firmware on this computer for about a year now. Im not sure why.
I am running a bootleg copy of Windows XP on this computer, I would not like to spend $149 to get Windows 7 if possible.
any thoughts on the matter would be greatly appreciated, thank you.

Why don't you take your 'old' MBP into your local Apple Store and have them check out everything that's wrong with it - and I mean everything? Then, when you get an estimate about how much it would cost to get the machine completely repaired, ask about the Apple flat-rate repair pricing?
It's worth a shot - and with what you may save, you can put in the bank for a new MBP.

What is causing a PowerMac G5/2.3GHz Dual Processor sudden abrupt shutdowns

Hi all
I am posting in hope that someone out there can help me solve this very puzzling problem.
The machine: A PowerMac dual processor G5/2.3GHz (early 2005). 1.5G RAM. 250G HD. SuperDrive. Radeon 9650.
The problem: When under some load, this machine will suddenly and abruptly shutdown as though someone pulled the power cord. There is no warning. Just a soft click, and it powers off. The machine can be manually restarted after the sudden shutdown with no problems.
This problem is very replicable. (eg go to a particular website, play an embedded video, and boom, the machine shutsdown. Each and every time.) It was replicated at an Apple Store and at two Apple Authorized Service Providers.
System.log said "PMU forced shutdown, cause = -122"
Before the sudden shutdown, the machine seemed to be operating normally. The fans did not noticeably speed up. Activity Monitor showed no more than 50% CPU activity for each CPU. Temperature on both CPU was around at 70C before the sudden shutdown. Temperature and activity on both CPU goes up and down in tendem.
If I use the Energy Saver system preference to change "Processor performance" to "Reduced", the problem goes away. (As measured by going to the same website and playing the same video. Even playing 5 videos simultaneously did not cause a sudden shutdown.)
What have I done #1: I have reformat the hard drive with a 7-pass security wipe, followed by a clean-install of Tiger which was then brought up-to-date using Software Update. I then installed Safari 4.0.3. No other software is on the machine except Tiger and Safari. (Later installed Hardware Monitor to get me a handle on the temperatures.) The problem persisted.
What have I done #2: I then installed a new PRAM battery and reset PMU using the switch on the motherboard. Resetting the PMU also resetted the PRAM. The problem persisted.
What have I done #3: I then took the machine to an Apple Store. They found that they can replicate the problem easily. But, after 3 days of running the Apple Service Diagnostic, the diagnostic software didn't find any problem. They also did a thermal re-calibration. That didn't help either. Without an error code from the diagnostic software, the only "solution" the Apple Genius offered was to start swapping CPU, power supply and mother board at my expense. And even then, he has no idea which component to start swapping first. (Two independent Apple Authorized Service Providers offered the same non-diagnosis and roughly the same "solution".)
Has anyone encountered such a problem before? What was the solution?
How about an educated guess as to what's wrong?
I want to, if possible, and if reasonable, repair this machine.
Thanks in advance.

This sounds almost exactly like the problem I have. My G5 is also an Early 05 2.3G. I tried every tip I found on the forums from UPS vs. wall socket to stock RAM vs. 3rd party to booting from external HDs, etc.. I currently have 10.5.8 on it and it's running using the "Reduced" processor setting in Energy Saver prefs.
I have also made a trip to The Apple Store where the AS folks ran their diagnostics but were usable to replicate my problem. I understand they "can't fix it if it ain't broke".
Aside from the "Reduced" setting work-around has ANYONE actually solved this problem definitively? Although I have no interest in spending $1000 to fix this, I can't imagine disposing of it on Ebay.
Assuming this is a hardware issue, this would mark the first insurmountable failure of any of the 10 or so Macs I have owned.
Anyone? Anyone?

Why can't I download 10.4 for my G4 Dual Processor?

I have an older G4 500 mHz Dual Processor Mac and two other macs (iMac & new MacBook Pro). I just purchased Adobe CreativeSuites3 and realized I can't install on my oldest Mac without upgrading the System software. I want to have the same version of CS on all Macs. I looked into upgrading to Leopard and discovered it won't work with my G4. So I went to upgrade from 10.3.9 to 10.4 and it appears that Apple will no longer sell a new version of 10.4! Am I looking in the wrong place? Will my G4 successfully run 10.4? How do I purchase a copy of it?

Tiger is available at many online retailers. Price Grabber has several listed. Make sure to get the full retail version.
Personally, I would stay away from E-Bay. A lot of machine specific versions get sold there, and unless you know what you are looking for, you'll end up with a disk that doesn't even work on your Mac.
Cheers! DALE

CHUD on a dual processor MDD running Leopard (10.5.8)

I finally got around to installing CHUD today and am wondering if some of you folks who have used it for a while might have some easy answers to a few questions.
I first tried version 3.5.2. It installed, but I couldn't adjust any of the settings. I then read on japamac's site that some MDD's could use 4.4.4. I installed that version and it does work (In fact, I'm posting this with one processor tied behind my back). However, there does not seem to be an option for nap mode.
Also, after I toggle between single an dual processor mode a few times, performance in dual mode seems to take a big hit. A restart solves the problem, but I'm wondering if this is normal.
Is there any way to get nap mode to work in a dual cpu MDD running 10.5.8?
Is there any way to get it to stay in single CPU mode when it wakes from sleep?
I read through the discussions at xlr8yourmac before posting this. It appears that some people have been able to get nap mode to work under Leopard, but they are not always careful to mention exactly which version of Leopard and CHUD they are using.

Hi-
When installing CHUD, it is also necessary to run CHUD remover to deinstall previous installations.
If not deinstalled, odd stuff happens.
3.5.2 is the one for dual processors.
Other versions have mixed dual processor support.
This is one of the claims that 4.4.4 works, but I have lingering doubts
http://discussions.apple.com/thread.jspa?messageID=5974655&#5974655
I may need to edit my blog page.....
It takes a script for automatic Nap enabling in a dual processor machine with 3.5.2.
See this thread:

Dual processor not showing up in Activity Monitor

I have a dual processor G5 PowerPC at work and when I look at the CPU Activity Monitor it shows me the activity on both processors. My Mac Pro at home is also a dual processor but when I look at the activity monitor it only shows one processor thread. Is this normal or is there something wrong with my Mac Pro? Anyone else notice this as well?

Hi KSStudio. A few questions to clarify.
1. Is this a dual or single cpu machine?
2. How many cores per machine?
Check it out...
Assuming you have a dual cpu (8 core) 2009 mac pro, when you use activity monitor choose > Window > CPU Usage. You should see a floating window with 16 panes. (8 panes if you have a single processor/4 core model) Under normal loads using 10.5 you should see some activity in all 16 panes. Under normal loads using 10.6 you should see activity in odd numbered panes. You will see activity in even numbered panes when the load is high. This is normal and due to Snow Leopard's improved utilization of processor technology.
Hope this helps.

Mac Mini Dual Processor?

I was told by a salesman at the guitar center that I could hook my mac mini G4 to a powermac G5 to boost the speed a bit. I don't really know how I'd do that, but my question is, if that's possible could I hook up a Mac MIni G4 to another one of the same speed and make that a dual processor set up...??
Mac Mini Mac OS X (10.3.9)

To my knowledge, there is (unfortunately) nothing as simple as that.
Still It should be "doable" to connect two macs to share their capabilities, but, due to the power used to run the process, you certainly won't end up with the power and ease of use of a dual processor machine...
