Information on 10G 10.2.0.1 64bit on Windows

Thanks for taking my questions!
Our campus is moving to peoplesoft and I was just asked to have a 64bit version of Oracle 10g up and running by June 6th. This database is just a demo db and this maybe just another install - I'm not sure. The problem is I don't have a whole lot of experience and would greatly appreciate some pointing in the right direction or some reassuring.
Background
First we currently have several 32bit windows boxes running oracle 10.2.0.3. but would like to utilize the 64bit so we no longer have the 2g application limit. We don't run rac or clustering - just plain oracle on windows. The client runs on a separate box. We are a small University with about 10,000.
Thanks again!

Questions
What's the difference between 10g x64 and 10g 64bit itanium?
What version of windows do you feel would be most stable for 64bit?
The little bit I read makes me think we may have the same memory issues with 64bit as 32bit. Might have to do with what OS we install - do you know of any issues?
Do you see any problems with installing 10g 64bit on a VM?
Do I need to apply the daylight saving patches or will these be included?
Would it be wise to just stick with the 32 bit windows box and try to use the 3g boot.ini switch to allow more memory?
Anything else I should be worried about?

Installation of Oracle 10g Developer Suit on W2k8 64bit Fail

Hi Team,
I installed oracle 10gR2 Database on windows 2008 64 bits. Now I am trying to install 10g Developer Suit on W2k8 64bit, following errors message is occured while installation.
javaw.exe - Entry point Not Found
"The Procedure entry point GetProcessImageFileNameW could not be located in the dynamic lilabary PSAPI.dll"
Please suggest me how to installed Oracle 10g Developer Suit on windows server 2008 64 bits.
Thanks in Advance

I don't know what it could be, but I have another question: why are you installing DevSuite on a server? DevSuite is for the developers and should be installed on a client, not a server. Maybe that is the problem.

Does oracle 10g 64bit need windows 64bit to support?

Must I install 10g 64bit on windows 64bit ?

Thead title is different from following question.
Not only on Windows: 64bit software requires 64bit OS, but 64bit OS does NOT require 64bit software. So you don't need to install 10g 64bit on windows 64bit, but you cannot install 10g 64bit on windows 32bit.

I got a problem on installing iTune-64bit on WIndows 7, error message says the folder "itunes" is on a locked disk or you do not have write permissions for this folder.

I got a problem on running the iTune 64bit on Windows 7, error message says " the folder "itunes" is on a locked disk or your do not have write permission for this folder. Any one ran into this problem ?
It worked before.

Open Disk Utility via Spotlight or in the Applications folder stored within the Utilities folder. Close all applications and 3rd party software and choose "Repair Disk Permissions." Reboot the computer when finished, and test to see if the issue is resolved.

I get the error "missing or invalid personalization information" This used to run, I'm now on Windows 7 64 bit. Anyone have any ideas please? Thanks.

Hi,
If my memory serves me right (it’s some while since I changed and I have not used Photoshop for some years…) I was running it on XP. I upgraded to Win 7 on a new machine but ported across files, programmes etc. I cannot recall if Photoshop ever ran on Win 7.
I have tried to reinstall but the CD is warped and despite applying pressure to it neither of my drives likes it. I have Photoshop 7 on my third hard drive, a portable drive, which came from the XP machine.
Sorry, long-winded but I hope it helps.

Installing Forms 11g 64bit on Windows Server 2008 64bit

Hi,
we are trying to install Forms 11g 64 bit with WebLogic 64bit on windows Server 2008 64bit and followed the short checklist of Jan Carlin :
- installed JDK 64bit
- installed WLS1032-generic
- started installation of Forms/Reports
Installation of Software worked fine and the configuration part did create the domain, but starting the domain fails (hang).

================================================
Somewhere I've read that the reason might be that the installation uses 32bit JDK, but I don't know if I did something wrong.
Somewhere else I've read that the reason could be the Path setting, which may include some directories with emphasis in the name which might be a problem for Weblogic.
Any idea or help is appreciated.
Thanks,
Mark

FYI,
This is related to Oracle-Bug 9370799 which hopefulls get sorted out sometimes. Having "(" or ")" somewhere in the PATH is not working. The workaround til the Bug is solved as of support is :
=================================
1) Remove the directory with "(" ")" from the System Path at install time only (this is what you have already performed)
2) Roll back the change so the System Path contains again the directory path with parenthesis
3) Copy in the clipboard the current PATH value and edit the <Middleware Home>\wlserver_10.3\common\bin\commEnv.cmd file and look for the following line:
if "%WL_USE_X86DLL%" == "true" set PATH=%PATCH_PATH%;%WL_HOME%\server\native\win\32;%WL_HOME%\server\bin;%ANT_HOME%\bin;%JAVA_HOME%\jre\bin;%JAVA_HOME%\bin;%PATH%;%WL_HOME%\server\native\win\32\oci920_8
4) Before this line define PATH to value you have in the clipboard without the reference to the directory with "(" and ")"
5) Save the commEnv.cmd and you should be able to start up your domain having the directory containing the "(" and ")" in the System Path
==================================
Thanks for your replies,
Mark

I have Photoshop CS5 Extended and it says updates available but when i download the updates it says updates failed please try again later, i have tried a few times and get the same message any help would be great i am running 64bit on windows 8

I have Photoshop CS5 Extended and it says updates available but when i download the updates it says updates failed please try again later, i have tried a few times and get the same message any help would be great i am running 64bit on windows 8.

I am running Windows 7 64 bit ultimate and have the same problem. My hard drive crashed, installed a new one and then reinstalled CS5 extended. Installation went fine, but can no longer open my camera RAW files from Photoshop (camera is a Canon EOS T2i. The message also tells me I am not eligible for the update. I am... and I cannot open my files and I could before. I can find nowhere to contact Adobe to tell me how to proceed. My daughter is all a registered user of the same product and she had no problems upgrading... we purchased ours each at the same time. I do know the difference is that I had to reinstall and she did not. If that means anything.

Hi
1. Installed RCU first see the link bleow
http://lamont-consulting.com/index.php/blog/obiee/11g/107-obiee-11g-rcu-install
The RCU will communicate with OBIEE
when you install obiee some information needed regarding the RCU.
2. Installed OBIEE see the link below

i have 3 machines
1. I have windows server 2008 64bit, Oracle Database 11g installed
2. I have windows server 2003 32 bit, RCU and OBIEE installed
3. I have windows XP SP3 32 bit, OBIEE desktop installed.
i hope the above links will help you.
if you have any queries, get back to me .. .

Oracle SGA Real Time Consumption Information(9i,10g and 11g)

Hello,
I need to prepare a comparative analysis report of SGA for an Oracle Production Instance
The analysis would show the pre-allocated memory to SGA components v/s real time consumption of memory by these SGA components. I need to do this for each of following components.
SGA itself
Fixed Size
Variable Size
Database Buffers
Redo Buffers
The pre-allocated memory to above SGA components can be obtained by querying v$sga. But from where do I get its real time(current) memory conusmption in Oracle Production environment.
In addition to above, i need the same information (pre-allocated and real time consumption) for following.
Keep buffer cache
Recycle buffer cache
Specific block size caches
Shared pool
Large pool
Java pool
streams pool
Which tables do I need to consider in order to derive 1)pre-allocated memory and 2)real time consumption for above mentioned SGA components
Please advice.
Thank you for your time in reading this post.
Thanks,
Ruchir

Hi,
Have a look at v$sgastat. Also, use statspack in 9i and AWR reports on 10g. Also, the size of the caches won't grow unless they are used. The parameters you have specified within the parameter file, like sga_target (10g onwards) and possibly the other pools if you have specified them, will show you what the caches can grow to.
For example, you could just log onto the DB and do show parameter sga_ or shared_pool and you will seee values for these. Also, it depends whether you are running in automatic memory management mode - where the sga_target parameter is set - or manual. 9i will be manual, but 10g could be auto. In manual case, 9i, check out the parameters individually.
Also, read the docs about the parameters shown and you will see what it says abotu them. There will be lots in the docs about performance tuning and monitoring of the instance. You might even learn some other interesting facts while reading through the docs...
Hope this helps,
Rob
