Oracle 10g - AMD cpu

Will oracle 10g under windows 2000, run on an amd box?

Hello allhi
Why is it that data pump is extremely slow in RAC environment? A 100G schema takes hours to export in RAC environment where as I can do the same in few minutes in standalone server. there could be zilion reasons why , but in your case there is propably higher resource usage on machines where RAC instance are than on the standalone one.
I am on RHEL 4 update 5, Oracle 10g, 8 cpu Dual-Core AMD Opteron with 32G physical memory. Does it need any tweaking that I'm overlooking here. I appreciate any advise or suggestions.Maybe you could start reading again those data pump documentation you already read, like this one for instance

How oracle.exe uses cpu

Hi all,
Does anyone know how Oracle 10g uses CPU on windows OS?
I'm interested to know is the oracle responsible for load balancing across the CPUs or OS do that.
Is there some Oracle technical documentation?
Thanks.

The OS handles CPU scheduling, not Oracle.
All of the Oracle docs can be had at http://docs.oracle.com

Tomcat 4.0 and Oracle 10g takes 100% CPU and grinds to a halt

Hi, I have a system to support that is currently running on Tomcat 4.0 on a Windows Server 2003 R2 SP2 machine with 3.06Ghz, 4Gb Memory, 2Gb Page file connecting to an Oracle 8.1.6 database on a Windows NT 4 virtual server with 3.2Ghz, 1152Mb Memory, 1536Mb Page file.
I have another Windows virtual server 2003 R2 SP2 machine with 2Gb of memory and a 4Gb page. This server has Tomcat 4.0 and an Oracle 10.2.0.3.0 database. I have made sure that the Oracle 10g classes12.jar file is used.
I am trying to run the application on the new server. In some tests I had users logging on one by one for the first 5 users - performance was great and the application ran faster than the current live system. When I then got another 10 - 15 people logging on the CPU stuck at 100% on the server, even exploring the server was almost impossible, and the application slowed down to unworkable.
We dont know if the problem lies with the very fact that we are trying to connect to a 10g database which is cost based and the application was written using rule based Oracle 8. Or is it the virtual server? Or is it the fact that we have both the application and the database on the same server.
I dont know if it is possible to have another Tomcat4.0 server running on our live server but connecting to the 10g database - what would happen with classes12.zip and classes12.jar? would there be a conflict?
I would really appreciate some help here. You should know though that I am not a hardened java programmer - I can dabble, but am an Oracle Forms, Reports, Discoverer, SQL person by trade. I am also a trainee DBA, so again am not an expert by any means.
Thanks in advance for your help

We're up to Tomcat 6. The important difference is the JDK supported. What JDK are you using for Tomcat?

If you find that those are drifting up over time, it's likely that the code isn't closing resources properly.

Start monitoring your Oracle connections and cursors to see what's going on. Install some filters to get raw timings on your Java calls. Without data, you're guessing in the dark.

Oracle 10g CPU patch

Oracle 10g on Windows server 2003. I need to do CPU patch. I follow the patch instructions, but I have some questions:
1. back up %oracle_home% directory. Is this just to copy whole directory to different disk?
2. clean shutdown all Oracle services: I know this includes db, listener, db control, anything else?
3. The Db has ASP application on the top. How to shutdown application? what components should I look at?
Webserver that uses Oracle client in the mid-tier?
4. What does ODBC application mean?
5.What does this mean? "make sure no applications are using the driver sqora32.dll"
6.What does "Oracle Instant Client" mean? Is this regular Oracle client tool installed on application server? I guess not.
Appreciate any help.

Thank you. I guess I need to make my questions clear:

My question: Is this just to copy to different disk OR you have other way to do it?It is a suggestion that will allow you to recover. In some cases (non-production) I will skip this step.
In production, I will ask the Backup team to make an extra backup of the entire ORACLE_HOME so they can do a quick restore if I mess up. (Then I'll be extra careful not to mess up.)
And yes, if you are comfortable that a disk copy will be sufficient to do a complete restore, then that should be OK as well.

I don't have ASM or ClusterwareThe you probably don't need to worry about it.
If you have any other Oracle stuff (BI Suite, SOA Suite, etc) that tries to log on to the database, these must be made aware of the outage - usually by shutting them down. Even if they are not on the same server.
>
3.What does this mean? "make sure no applications are using the driver sqora32.dll"
My question is where and how can I find this DDL?
Are you seriously saying you do not have access to an OS file-search tool?
At least one copy is in ORACLE_HOME/bin
>
4. What does "Oracle Instant Client" mean? Is this regular Oracle client tool installed on application server? I guess not.
My question is that is this tool to get installed on Oracle server or application server? My vendor installed the Oracle server for us, how do I know if this tool got installed or not?It is a completely separate download. It is usually installed at the client, not on the server. However, since you have a vendor install, you may want to discuss this with the vendor.
The big challenge with Instant Client is that it is not an 'install' . It is just an unzip into an arbitrary directory, and does not get recorded in the registry. So almost impossible to find without the SysAdmin's install notes.

in addition you might want to trace the session to find out what it is waiting for. In 10g you can use the DBMS_MONITOR package to enable the tracing, and then use the "tkprof" utility as outlined in the article to get the trace file generated analyzed.
You can also use the V$SESSION view (BLOCKING_SESSION_STATUS, BLOCKING_SESSION, BLOCKING_INSTANCE) to find out if the session is blocked for any reason, although it shouldn't consume CPU in that case.

In Oracle 10g,nmupm.exe runs at 100% CPU usages

Hi There this is Bal Mukund Sharma from Computer Associates,HYD.I have recently installed Oracle 10g on windows 2000 server with 1 GB RAM,i have observed that nmpsupm.exe which is under the bin directory under c:\oracle\product\10.1.0\Db_1\nmupm.exe.is consuming all CPU resources.
when i set all Oracle services to manual and restarted the machine then it shows normal CPU usages. Can you please suggest something regarding this.

Oracle 10g --- cpu usage

Hi,
i just installed oracle 10g on my laptop and it uses too much resources. cpu usage is always around 96-100%. whats the reason that it starts by itself and is taking too much resources.
Raj

The reason it starts up automatically is because the service (OracleService<name>) is set by default to auto start. You can change this to manual if you don't want the database to startup every time you reboot your laptop.
As far as CPU usage...Do you have a real-time virus scanner installed? Those things will kill a laptop. I'd rather have the virus (not really).
I have 10g on my Windows XP desktop and the CPU usage is normally at 0%. It takes up a lot of memory, but if it's mostly idle, it doesn't consume much CPU resources.

Which processor is best for Oracle 10G database : Intel or AMD

Hi,
I am buying a new laptop for 34000 rs (700$) . I am configuring it for my office use. i am oracle apps developer.
Can anyone suggest shud i go for Caompaq or Acer?
Which processor will best handle Oracle 10G database? Inter Core Duo or AMD Turion?
Thanks,

Hi,
I am not sure about "hosting a serveice means". i will be installing Oracle discoverer administrator and optionally pl/sql developer.
I remember that we had installed oracle10g on my friends AMD desktop....and that had killed the performance like crazy.It must have something to do with the configuration of instance. I have at least two desktops running AMD and it works perfectly fine.
>
The laptop i m buying is *250 GB HDD, 2 GB RAM and windows vista*.As Nicolas has rightly pointed out in his post, which version of Vista is this? Remember that Vista Home edition is not supported by Oracle. You might get the things to run but you cannot guarantee the stability.
The only thing i m confused bout is whther i shud go for AMD or Inter core processor.
In this case, this would be a matter of personal choice. Both processors are at par with each other (now I am not going into the details of architecture and other things).

Installation of Oracle Interim patches (CPU) prior to upgrade to Oracle 10g

Hello Gurus,
We will be upgrading our Oracle 9i database to Oracle 10G. One of the requirements is to have version Oracle 10.2.0.2 and may need to apply the CPUJAN2008 interim patches. My question is would it be safe to pre-install everything (Oracle Patch set + CPUJAN2008) before I do the upgrade?

Oracle 10g on HP-UX, Terrible Poor Performance!!

Hi All,
I setup an Oracle 10g on HP-UX 11iv1. Server is a HP 9000, 4 CPUs (750
MHZ). It is connected to Disk System 2405 (Virtual Array 7110). Fiber
Channels are connected at 2 GB speed.
I installed a cluster 10g database. First I installed CRS and after
that I installed oracle database. ( I want to test clustered database
with one instance)
I installed every thing line by line as oracle document wrote.
All the things, kernel parameters, patches, are like oracle wrote in
its document.
I installed Golden quality package June 2004.
I increased shmmax to 2.3 G . My SGA is 1.7 G And change some other
parameters as Sandy Gruver wrote in Best Practices for Oracle on HPUX.
I used oracle new storage system called ASM for this case.
When I put the system under the load, I was monitoring the system
carefully.
I started gmp. When we sent some quarries to database (It is not heavy
load, I tested it with a Linux system on proliant ML570 without any
problem), suddenly DISK section in gpm changed to red (critical ) I
read the warning. It said "Disk bottleneck probability = 100%". I
changed the output of disk report to "Report IO by Disk"
"DISK%" was 100% and "RAW IO RT" was about 1000 for two disks ( This
two disks dedicated for ASM). In this situation CPU idle time was 1% or
2% for all the CPUs but load average was about 1. Performance is not
acceptable at all ( In comparison with Oracle that installed on Linux).
Glance reported Disk was in Critical situation.
I think the problem is IO or something about Disks
I used HP Disk System 2405. Fibber channels on both server side and
Disk Array side are configured at 2 Gb and topologies are
PTTOPT_FABRIC.
Is it ok that RAW IO RT about 1000 for each LUN?
Why Disk% in glance/report IO BY Disk/ was 100%?
I found an error in STM logs about I/O.It said:
Entry type: I/O error
Product: Fiber Channel Interface
Logger: td
It logged this error about 12 times during the test.Any comment?
Regards,
Hasan

Sorry, I have not a solution for your problem, but similar things happen on our installation on Solaris 5.8 with Oracle 10:
I have a banking business solution from Windows/SQL Server 2000 to Sun Solaris/ORACLE 10g migrated. In the test environment everything was working fine. On the production system we have very poor DB performance. About 100 times slower than SQL Server 2000!
Environment at Customer Server Side:
Hardware: SUN Fire 4 CPU's, OS: Solaris 5.8, DB Oracle 8 and 10
Data Storage: Em2
DB access thru OCCI [Environment:OBJECT, Connection Pool, Create Connection]
Depending from older applications it's necessary to run ORACLE 8 as well on the same Server. Since we have running the new solution, which is using ORACLE 10, the listener for ORACLE 8 is frequently gone (or by someone killed?). The performance of the whole ORACLE 10 Environment is very poor. As a result of my analyse I figured out that the process to create a connection to the connection pool takes up to 14 seconds. Now I am wondering if it a problem to run different ORACLE versions on the same Server? The Customer has installed/created the new ORACLE 10 DB with the same user account (oracle) as the older version. To run the new solution we have to change the ORACLE environment settings manually. All hints/suggestions to solve this problem are welcome. Thanks in advance.

Repeated ORA-12547 Messages after installing Oracle 10g

Hi,
I installed Oracle 10g on a Redhat ES 3 box, and the install went okay, but when I try and interact with the server I get the message:
ORA-12547: TNS: lost contact
For example, if I use the Database Configuration Assistant to attempt to create a database, I will see the above message when it begins the database creation process, or if I try to interact with the Oracle server using sqlplus I will see the above message after each command entered.
I had recently tried to install Oracle 8.1.7 on the same box, but abandoned that after deciding that the effort required to link Oracle 8 on RHES3 just wasn't worth it. I have been told that this previous partial installation may be the cause of the problem, and have been advised to uninstall Oracle 8, uninstall Oracle 10g, and reinstall Oracle 10g. I find it hard to believe that it would require such an action to solve this problem. Is there any configuration changes I can make to resolve it? Also, what does this message actually mean?
I am new to Oracle, so thanks for any help with this problem.
Colm.

My last message asking for a grater degree of specificity was not overly specific, hence I am posting the kernel parms that I have set with the hopes that you will spot one that I set improperly or one that I neglected to set.

After installing the operating system, I added this package
rpm -Uvh orarun-1.8-109.5.i586.rpm
and enabled the user oracle.
I you login as user oracle, the following error message is displayed :
error while loading shared libraries : librt.so.1 : cannot open shared object files : no such fileSuse support answers to this question : Oracle 10g is certified on SLES9, but the orarun package is only supported for SLES9 i386 ?
This is correct, but did not help me to continue my installation.
Any ideas ?
Best regards

OracleAS 10g R2 bug?

I have a test server with this configuration:
Win2K Advanced Server
1 CPU
2 gig ram
2 gig swap
I had OracleAS 10g R1 v9.0.4.1 on it. I un-installed everything per note 124353.1. I then installed the Infrastructure and Middle Tier on this server. Oh, I'm using the Portal and Wireless installer.
No problems at all and everything appears to be working.
Going to the server http://server_name I see everything in a foreign language (index.html). View source shows this tag at the top <html LANG="en.US"> so it should be in English but it is not.
I then try the Suite link (WNIntro.htm) and it is also in a foreign language.
Then the demos page (ASDemos.htm) is in English though.
I have been using IE 6.0 on a Windows 2000 Desktop with all of the latest patches installed.
Just for fun, I then tried bypassing Web Cache. http://server_name:7777 and now in IE everything is showing in English. With Firefox, everything is in a foreign language still even when going straight to Apache.
With R1, I never saw anything like this. We have several servers running 9.0.4.1 and no Apache pages have ever come across in a foreign language.
Example:

Jon,
Looks like a bug to me. Try this workaround: copy all of the *html.html files found under $ORACLE_HOME/Apache/Apache/htdocs to files with the same name but with the html.en extension. so for example, copy index.html.html to index.html.en.
BTW, what is your browser language setting? Is it "en" or "en-US' as its default langauge?
