Oracle VM Server 2.2.1 - Extra mount options for /OVS
Hi,
we would like to know how to add extra mount options (rw,hard,intr,tcp,rsize=32768,wsize=32768,timeo=600) to /OVS in Oracle VM 2.2.1.
In version 2.1.5 and lower it was possible by adding those options together with the UUID in /etc/ovs/repositories.options
How to manage mount options in Oracle VM 2.2.1? I've tried the same and no success.
Best regards and thanks in advance,

Since we have seen some I/O problems which causes high CPU Wait for some VM (those which contain postgres databases with high I/O activity) we finally decided to apply those NFS options to see if it solves the problem. If it doesn't work we will analize which options can improve the performance.Marc, why not just use the OVS' NFS mount for the system/root partition and mount an NFS volume from within the guest itself? That way, you can set all the parameters you need. Also, the netfront drivers (I'm told) are slightly more efficient that the blockfront drivers, so you could even see a performance improvement.

Configuring oracle management server 9i using create new repository option
hi ,
i am trying to install oracle management server using the the option "create new repository "on a system on which oracle database is already installed .after installing oracle management server "configuration assistant appears .the second option is to select a database repository .
first of all can i select the database that was prevouisly installed on my system
or do i need to create a new database before installing oracle management server. but as i did not install any database for oracle management server before i am trying to select the database that was previuosly installed on the system but i gave me a tns error that it could not resolve the service name .after that i noticed that the oms listerner was up and registered . i am trying to stop this listener and start the database listerner so that it may not give me this error.can some one help me out configuring oracle management server on a system creating a new repositoryI suggest you to create a different database for the OMS repository. This database can be used for other tools that may require a repository, such as recovery manager.
On the connectivity issue, I suggest you to verify your listener is up and running and it doesn't need to have the instance registered, as of course, it is a new instance. Make sure it is started. For additional troubleshooting on the connectivity issue, you may post the specific tns-12XXX error message displayed.

Mount options for ZFS filesystem on Solaris 10
Do you know some recomendation
about mount options for SAP on Oracle
with data on ZFS filesystem?
Also recomended block size required.
We assume that file system with datafiles has 8kb block size
and offline redologs has default (128kB).
But what about ONLINE REDOLOGS?
Best regards
AndySUN Czech installed new production HW for one Czech customer with ZFS filesystem on data-, redo- and archivelog files.
Now we have performance problem and currently there is no SAP recomendation
for ZFS file system.
The HW which are by benchmark about tvice power has worst responses than
old hardware.
a) There is bug in Solaris 10 - ZFS buffers once allocated are not released
(generally we do not want to use buffering due to prevence of double
buffering)
b) ZFS buffers takes about 20GB (32GB total) of memory on DB server
and we are not able to define huge shared pool and db cache. (it may be possible
to set special parameter in /etc/system to reduce maximum size of ZFS buffers to e.g. 4GB )
c) We are looking for proven mount option for ZFS to enable asynchronious/concurent io for database filesystems
d) There is no proven clear answer for support of ZFS/SOLARIS/Oracle/SAP.
SAP says It is Oracle problem, Oracle does not certify filesystems from Jan2007
any more and says ask your OS provider and SUN looks happy, but performance
goes down and it is not so funny for system with 1TG DB with over 30GB grow
per month.

I need to attach an iMac G5 to mounting arm. The rep that sales the mounts said that his will attach to standard flat screen interface called VESA. The VESA interface is either 75mm or 100mm. Anyone tried to attach an iMac G5 to one of these?
ThanksThanks.
In another thread I found that the Apple Store sells a mounting bracket that replaces the stand. This bracket has VESA compliant holes at 100mm.

Installation of the VeriSign digital certification in Oracle HTTP Server
I am not obtaining to generate to the pair of keys and the CSR in Oracle HTTP Server, will have some tip I is thankful.
Thanks
LeandroHi Leandro,
Here are some steps to setup digital certificates into Oracle HTTP Server for Unix.
1. The temporary working directory is /u01/tmp/myssl.
2. The contents of <9iAS_HOME>/Apache/open_ssl/bin have been copied to the
temporary working directory created in Assumption #1.
3. SSL file names are priv.key (private key), certreq.csr (certificate request),
and cert.crt (SSL certificate). The actual SSL certificate file could be
named other than 'cert.crt'.
4. By default, SSL is configured using port 443, which requires ROOT access to
start the web listener.
If you want to change this from the default port, you will need to change
the following two parameters in the httpd.conf file to an unused port number:
Listen 443
<VirtualHost default:443>
5. All necessary UNIX environment variables are set correctly for your Oracle
product before implementing these procedures.
6. User must be familiar with UNIX concepts like shell navigation, UNIX
environments, file manipulation/search, file copy/backups, etc.
How to Request and Configure an SSL Certificate for Oracle9i Application Server
Step-by-Step Instructions:
1. Change your present working directory to the temporary working directory, e.g.,
/u01/tmp/myssl. Ensure the contents of <9iAS_HOME>/Apache/open_ssl/bin have
been copied into this temporary working directory.
2. Copy 5 large files, each at least 250KB, into your temporary working directory.
Suggest looking in any /bin directory for large sized binary files. Execute
the following command to generate the random character file:
% openssl md5 * > rand.rnd
3. Execute the following command to generate the private key (priv.key):
% openssl genrsa -rand rand.rnd -des3 1024 > priv.key
- when prompted, enter a "PEM pass phrase" password
- re-enter password when prompted to verify password
-- remember the pass phrase password you entered
- this command generates the priv.key file and associated pass phrase
- set permissions on the priv.key file to prevent unauthorized editing
% chmod 400 priv.key
- backup the priv.key file to a secure location
NOTE
The PEM pass phrase must be at least 4 characters in length. Remember this
pass phrase, you will be prompted to enter it in the next step and each
time you start up the Oracle HTTP Server (OHS) in SSL mode.
Optionally, you can unencrypt the value of the private key, so that you
will not be prompted for the PEM pass phrase every time you start up OHS
in SSL mode.
To unencrypt the private key, execute the following two commands (Note:
ensure file permissions set to r+w):
% cp priv.key priv.key.bak
% openssl rsa -in priv.key.bak -out priv.key
- the demo certificate shipped with Oracle9iAS does not require a pass
phrase to start OHS in SSL mode.
- on UNIX, to generate the certificate request and start OHS in SSL mode,
the pass phrase must be entered, unless you executed the above steps
to unencrypt.
- on Windows NT/2000, if a certificate is used that has a pass phrase,
the OHS will hang; therefore, on Windows NT/2000, you must execute
the steps to unencrypt.
4. Execute the following command to generate an SSL certificate request
(certreq.csr) based on your private key.
% openssl req -new -key priv.key -out certreq.csr -config openssl.cnf
- when prompted, enter the "PEM pass phrase" set when the private key
was created.
- when prompted, enter the requested fields that make up the
Distinguished Name.
-- each entry must be valid information, i.e., email, state, location, etc.
- when prompted for the "Common Name", you MUST enter the fully
qualified name which will be accessed via client browsers; e.g.,
if clients will use:
https://mysite.domain.com
-- then, you must enter mysite.domain.com as the "Common Name"
- the requested 'extra' attributes, i.e., "challenge password" and
"optional company name", are OPTIONAL; just hit ENTER to use NULL values.
5. You should now have the private key and certificate request files (priv.key
and certreq.csr) in your temporary working directory.
NOTE
At this point, you can use your certificate request file 'certreq.csr' to
order a valid SSL certificate from any CA-vendor, e.g., Verisign.
After you receive your SSL certificate, skip to Step #6 for instructions
on how to deploy your SSL files.
OPTIONAL
You can start 9iAS in SSL mode (see Step #12) and test the pre-installed demo
certificate and private key included for testing purposes.
It is a good idea to test to be sure the Oracle HTTP Server SSL mode works
successfully before deploying your new SSL certificate. To try these demo
files, access the 9iAS index page in a browser using the HTTPS protocol and
the appropriate SSL Listen port. URL format:
https://myhost.domain.com:<ssl_port>
The user will see a Security Alert (IE), or New Site Certificate (Netscape)
warning message, click Continue/Next to accept.
OPTIONAL
To create a self-signed certificate, execute the following commands:
(csh) % setenv RANDFILE rand.rnd
<sh or ksh> % export RANDFILE=rand.rnd
% openssl x509 -req -days 30 -in certreq.csr -signkey priv.key > tempcert.crt
- when prompted, enter the "PEM pass phrase" set when the private key was created.
- this command generates a temporary self-signed certificate file 'tempcert.crt'
valid for 30 days, which can be used while awaiting a valid SSL certificate
purchased from an authorized CA-vendor.
- if this option is used, after generating the 'tempcert.crt' file, skip to
Step #6 for instructions on how to deploy your SSL files.
OPTIONAL
These steps are specifically for requesting a TRIAL certificate from the
CA-vendor Verisign.
- Go to www.verisign.com and click on "Free Guides and Trials" link and
follow instructions to request a "Free Trial SSL ID". During this process,
you will be asked to provide certificate request information.
- Open the 'certreq.csr' file using your text editor of choice.
- Starting with "-----BEGIN NEW CERTIFICATE REQUEST-----" copy all lines
including the BEGIN and END of certificate lines.
- Paste this copied data into the Verisign page where requested and continue.
- You will see the Verisign web site decode your certificate request
information. This decoded information is presented to you to verify it is
correct. If it is, then continue with the process.
- You will be presented with another set of questions from Verisign. Be sure
to answer with the correct email address, as this address will be used to
send your SSL certificate.
- After you answer all these questions, you will be sent a TRIAL 14-day
SSL certificate via email.
- WARNING! You must follow this step carefully, you cannot copy and paste
information from an email to a new text file. After you get your TRIAL
certificate, save the entire email message to a text file. Open this file
using your text editor of choice. You will see the email address header
information and the line:
-----BEGIN CERTIFICATE-----
- Delete all text that appears before the -----BEGIN CERTIFICATE----- line.
The modified file should contain only certificate information. After you
delete the email header, save this text file inside your temporary directory
with the filename 'trialcert.crt'.
6. Now you are ready to configure Oracle9i Application Server (9iAS) with your
SSL certificate files.
7. Back up your existing <9iAS_HOME>/Apache/Apache/conf/httpd.conf file.
8. Open the httpd.conf file with your text editor of choice.
9. Edit the following httpd.conf directives to use your generated private key
and SSL certificate file, which could be the filename for either the
temporary self-signed certificate, the TRIAL test certificate, or the
purchased valid certificate. The information following the # symbol are
comments.
NOTE
The directory of the SSL files (private key and certificate file)
can reside in any location you choose. The temporary working
directory will continue to be referenced in these procedure steps.
# use the appropriate (i.e., valid, temporary, or trial) certificate filename
SSLCertificateFile /u01/tmp/myssl/tempcert.crt
#private key from Step #4 above:
SSLCertificateKeyFile /u01/tmp/myssl/priv.key
10. Save your modified httpd.conf and exit the text editor.
11. Log in as authorized user (if default ports 80 and 443 are used, ROOT user
must execute commands in next step).
12. Execute the following command to stop, then start Apache in SSL mode
(ensure proper UNIX environments are set; else, execute command from
<9iAS_HOME>/Apache/Apache/bin.)
For Oracle8iAS 1.x:
% httpdsctl stop
% httpdsctl startssl
For Oracle9iAS 1.0.2.x:
% apachectl stop
% apachectl startssl
- when prompted, enter the "pass phrase" created in Step #3.
-- not required if you unencrypted the private key file
- when the Oracle HTTP Server starts successfully in SSL mode, access the
9iAS index page in a browser using the HTTPS protocol and the appropriate
SSL Listen port. URL format:
https://myhost.domain.com:<ssl_port>
- if using a temporary self-signed or TRIAL test certificate, the user will
see a Security Alert (IE), or New Site Certificate (Netscape) warning message,
click Continue/Next to accept.

How to install Oracle VM Server 2.2.0 as 32-bit mode on a 64-bit machine.
Gurus,
If I am not wrong, the Oracle VM Server 2.2.0 installer for 32-bit and 64-bit are the same file.
I have AMD 64 bit machine, when I install Oracle VM Server 2.2.0, it installs as 64-bit.
However due to requirement, I want to install Oracle VM Server in 32-bit mode.
Will appreciate the steps.
Regards,
KrishnaKrishna,
Please note that the zip file from the Oracle eDelivery/Linux site contains a single Oracle VM server ISO file; this file is used for both x86 and x86-64 hardware. The Oracle VM server install routine automatically detects the hardware platform and installs the appropriate 32-bit or 64-bit Xen hypervisor. Regardless of the hardware platform, 32-bit or 64-bit, dom0 is 32-bit. Will a 32bit dom0 meet your business requirements?
Could you please let us know the business requirements re 32bit?

Oracle Application server 10g on RHEL 4
Hi Experts,
I have a oracle application server 10.1.3 which is installed on a IBM blade server which has Red Hat Enterprise Linux 4 (RHEL4) as operating system.
The server has a RAM of 8GB and has 4 processors (Intel XEON 3.8 GHz).
I have deployed an application on this server, the application has been developed in Oracle ADF (ver 10g). The jdeveloper version used for development was 10.1.3.2.0
I want to ask how many concurrent user session this server can handle concurrently. And how can i perform a stree or load testing on this server.
Are there testing tools available for stress testing (pls provide any name).
Using this configuration can this server can it handle around 500 sessions of users.
Thanks in advance .May be possible but it is probably not tested by Oracle nor is it supported as error correction support for OAS 10g has finished more than a year ago.
A good starting point is My Oracle Support Note [url https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=564174.1]564174.1, "Oracle Application Server 10g (10.1.2) Installation Requirements for Linux OEL 5 and RHEL 5".

Oracle application server 10.1.3.1.0 install - JAVA error
Hi Everyone,
I am trying to Install Oracle Application Server 10.1.3.1.0 on 32 bit Red Hat Enterprise Linux Server release 5.8 (Tikanga)
When running the Installer, I use the -ignoreSysPrereqs option because 10.1.3.1.0 is only supported with Linux Server 4, I believe. But I know people have installed it on Linux 5.7 and 5.8
anyways, Oracle application server gets installed and asks me to run root.sh. I run root.sh and then hit the OK button to proceed,
At this point, it tries to run the configuration assistant and fails right away with the following error:
