Is ORACLE slower on Windows then on Linux ?

Hi,
I'm suppose to choose the platform for Oracle .... Linux or Windows 2008 Server ...
Ones we've installed Oracle on Windows 2003 Server and it was really slower like 200-300% ..... we did simple default install
Does anyone know if this is a fact that Oracle will run slower on Windows platform then on any other ? Any experiance with that ? If we are talking about 5-10% then this is ok and I'll stick with windows ...
Cause I know how to deal with windows much more then how to deal with Linux admin, install and other stuff ...
Thank you...

Hi Charles,
Installing a virus scanner on the server, especially if it is permitted to scan program and data files used by Oracle.Ha, that a good one! That the FIRST thing I check!
Also, I've seen high demand screensavers (fractals) clobber Oracle performance . . .
Oracle on Windows uses a thread modelThat's actually one of the few "positives" about running Oracle on Windows . . .
rather than providing a performance comparison between Linux and Windows.Fine, try here:
www.dba-oracle.com/oracle_tips_linux_oracle.htm
"Roby Sherman performed an exhaustive study of the speed of Oracle on Linux and Microsoft Windows using identical hardware. Sherman currently works for Qwest Communications in the data technologies group of IT architecture and transversal services. He is a recognized expert in designing, delivering, tuning, and troubleshooting n-tier systems and technology architecture components of various size and complexity based on Oracle RDBMS technology.
Sherman concludes that Linux was over 30% faster:
"From perspective of performance, RedHat Linux 7.2 demonstrated an average performance advantage of 38.4 percent higher RDBMS throughput than a similarly configured Windows 2000 Server in a variety of operational scenarios." Sherman also notes: "Another point of contention was Window's lack of consistency between many database administrative functions (e.g., automated startup, shutdown, service creation, scripting) compared to what DBAs are already used to in many mainstream UNIX environments (e.g., Solaris and HP-UX)."
Mr. Burleson's comments seem to be out of line. No, I'm right on the money.
*I've seen enough companies get burned by Windows (unplanned outages, data corruption) to speak with confidence.*
Bottom line, it's malfeasence to recommend any OS platform for a production database application that has an unsavory history.
It does not take a genius to figure out that an OS with this kind of history should not be used with any data that you care about:
- "blue screen of death"
- legandary security vulnerabilities
- memory leaks you could drive a truck through
- Patching weekly
- The world's most incompetant tech support
I'm not alone in this opinion:

Good point on the screen saver.
Comparing Windows 2000, released in March 2000, with Red Hat 7.2 which was released in ... sorry, forgot the date, but I put in a couple servers running that release of Linux into service in 2001. I was kind of hoping that you would have an article which pits Windows 3.1 against the original Linux release. :-)
You might be happy to know that things have changed significantly since Windows 3.1, and also significantly since Windows 2000. There were many improvements in Windows 2003 over Windows 2000 (I happened to read a couple large books on the subject of Windows 2003 Server a couple years ago). This page contains a couple links that you may want to browse:

Windows sucks... I have heard that the Microsoft Windows operating system is on barcode scanners, phones, and even car navigation systems. I had no idea that vacuums also utilized Windows, thanks for the heads-up:

Regarding blue screen of death, those are rather rare with versions of Windows since the release of Windows 2000. The last blue screen that I saw on a server happened when an ECC memory module started experiencing multiple hardware bit errors which could not be corrected by the ECC memory logic. The server hardware forced the blue screen to prevent data corruption. The previous blue screen? A Windows NT 4.0 Server (circa 1996) when a new RAID controller was added to the server.
Regarding legandary security vulnerabilities, well I don't think that it quite qualifies as legendary. However, given the wide usage of Windows (particularly by people just starting to learn to use computers), there will very definitely be more security issues to contend with - Windows often offers a larger attack surface than other operating systems. Yes, there have been many security problems over the years.
Regarding memory leaks you could drive a truck through, I have to say that in a server environment I have not experienced that problem. On a desktop environment, I would say that it is typically the fault of poorly written applications which cause the memory leaks. Windows will often clean up after the poorly written applications when they are closed.
Regarding patching weekly, yes there are typically frequent security and bug fixes released for the Windows platform, but I suggest that if someone is patching weekly on a server, there is probably a larger problem to be addressed.
Regarding the world's most incompetant tech support, I am not sure that I follow your logic:
define:incompetant

"Did you mean: define:incompetent
No definitions were found for incompetant.
Suggestions:
- Make sure all words are spelled correctly.
- Search the Web for documents that contain 'incompetant'"
As previously stated, consideration should be given to the operating system which is most familiar to the OP.

Advantages/Disadvantages of installing Oracle RAC on Windows 2003 VS Linux

Hello Guys,
I am not very good with linux, have to create a Oracle RAC environment using dataabse 10g.
I just need to know the advantages/disadvantages of configuring RAC on windows and on linux operating system.
Please help me with this. Please also specify what is the best available windows and linux version to configure RAC.
Regards,
Imran

Go with th eOS you have the skills in, if you have onsite expertise in windows then it makes no sense to use Linux because some guy on the internet says its better. Windows can be a highly available server OS when is managed by professional well quallified adminstrators.
Personally I would use linux because I am more familiar with the OS than windows. I also find oracle makes more sense on a *NIX type platform but there are shops that run oracle on windows with the required high availability.

Help! Im getting really confused! Linux Oracle 9 to Windows 2000 MS SQL.

Please can someone explain the process and what needs doing.
I am trying to connect an oracle 9i database which is running on Linux Red Hat Enterprise 4, to a MS SQL database which is running on Windows Server 2000.
I have read the following document https://metalink.oracle.com/metalink/plsql/f?p=130:14:1119006956529253705::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,231458.1,1,1,1,helvetica
But I am confused as to where each configuration file sits.
I have downloaded oracle 9i for windows and installed the OTG and tg4msql on the windows 2000 server. On the windows 2000 server I have created the following files:
tnsnames.ora:
TG4MSQL.domain.name =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = tCP)
(HOST = <IP_ADDRESS>)
(PORT=1521) )
(CONNECT_DATA =
(SID = tg4msql))
(HS=OK)
Listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle9i)
(PROGRAM = extproc))
(SID_DESC =
(SID_NAME = tg4msql)
(ORACLE_HOME = D:\oracle9i)
(PROGRAM = tg4msql)
(ENVS=LD_LIBRARY_PATH=D:\oracle9i)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = IPADDRESS)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
inittg4msql.ora
HS_FDS_CONNECT_INFO="SERVER=<IP_ADDRESS>;database=<MS SQL DATABASE NAME"
HS_FDS_TRACE_LEVEL=0
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
HS_FDS_TRACE_LEVEL=OFF
Then on the Linux server I have the following tnsnames.ora:
TG4MSQL.DOMAIN.NAME =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = <MS SQL IP ADDRESS>)(PORT = 1521))
(CONNECT_DATA =
(SID = tg4msql))
I then created a database link on the Linux Oracle server:
CODE
create database link tg4msql connect to "sa"
identified by "password" using 'tg4msql';
I then tried a:
CODE
select * from all_catalog@tg4msql;
and get:
Ora-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NEWTORK/NCR message 12571
ORA-02063: preceeding 2 lines for TG4MSQL
I feel I have done everything I have read but its not very clear where everything has to be put or how it all ties together.
Any help would be useful!
Thanks.

well I don't see how your ODBC driver on linux is configured. You need one (ODBC driver on linux, it's not there by "default") You can buy one or use a free one
find it here
http://www.unixodbc.org/
then once you set up ODBC and able to connec to your SQL SERVER from command line using iSQL or TSQL from linux then do all these steps you described and it should work.
I didn't have any problems setting it up, works like a charm

Is the Windows firewall active? Have you enabled the port on the firewall, if it is?

Can I connect window device like modem, mobile in oracle forms,if possible then how?

Can I connect window device like modem, mobile in oracle forms,if possible then how?

Hi Tony,
So explain where you would see your notification?I just mention, Leave module, there are many other module. For example In Purchase Purchase Requigition , Production Module Production Complite , Delivery Module Delivery Ready.
For this it will better to show at respective Menu.
In the Window title?Another good Idea !
You could have a timer trigger that runs every 5 minutes and checks a notification table, if there is an unacknowledged notifcation, then you could change the Window title of the formas app to show a (1) at then end of it.Timer has a bad this.. For example, if i make a timer and run every 5 min. then if user works on a form, timer will hide the form and show the timer window.
Isn't it ?
Would that do, or do you need more?Yea.. More..It will be like facebook. If any notified work is done by any person, light will go off.
Thanks for your interest and suggestion...

Can I use Transportable table-space after creating database on Linux?
Please give me all the steps in doing so.
Thanks in advance,
Rajini.

Rajini,
this forum covers migrations from foreign databases to Oracle. Your "only" change the platform of your Oracle database release. This question is better handled in the Database Forum

Oracle Enterprise Manager -- Windows or Linux

Hi all,
Actually I'm planning to start using Oracle grid control to monitor all the different databases (Oracle 8i, 9i, 10g, 11g & SQL server 2000,2005,2008) within our organisation. But i am unable to decide whether to install on a windows server or Linux server.
Can you pls advise what are the different factors to take into consideration that will help me take this decision.
Thanks.
Regards,
Poonam

Install Oracle 11gR2 Express Edition on Ubuntu Linux 11.04 (64-bit) Howto

h2. Install Oracle 11gR2 Express Edition on Ubuntu Linux 11.04 (64-bit) Howto
Version: B
Author: Dude, 24. May 2011
The following are step by step instructions how to install Oracle 11gR2 Express Edition (Beta) under Linux Ubuntu 11.04, 64-bit.
Access to the Internet is required.
The instructions cover the following additional topics:
- Converting Red Hat based Oracle XE installer to Ubuntu.
- Work-around for missing /sbin/chkconfig tool.
- Install Oracle XE into a different directory or disk volume.
- Relocate and configure the Oracle user and default login directory.
- Uninstall, reconfigure and perform first database backup.
- Notes and web links.
- Troubleshooting
h3. A) System Setup and Prerequisites
h4. A.1. System Access
You will need terminal command line, root and system console access to perform the setup tasks.
To open a Terminal at the system console:
Menu Applications > Accessories > TerminalThe following commands will enable remote ssh login with root access:
sudo apt-get install openssh-server
sudo passwd root
Verify:
ssh root@xe_server_host_nameh4. A.2. Software Prerequisites
The following is required in order to install Oracle 11gR2 XE:
sudo apt-get install alien libaio1 unixodbcThe following is not required, but it will fix backspace and arrow keys in case you prefer using the vi-editor:
sudo apt-get install vimh4. A.3. System Swap space
Minimum swap space required is 2 GB. You can increase swap space if necessary using a swap file:
To analyze current swap space and memory configuration:
sudo cat /proc/meminfo
To install a 1 GB swapfile named swapfile in /, for example:
sudo dd if=/dev/zero of=/swapfile bs=1024 count=1048576
(this may take a while)
sudo mkswap /swapfile
sudo swapon /swapfile
sudo cp /etc/fstab /etc/fstab.orig
sudo echo '/swapfile swap swap defaults 0 0' >> /etc/fstab
Verify:
sudo swapon -a
sudo swapon -sh4. A.4. Kernel Parameters
Oracle 11g XE requires the following additional kernel parameters:
sudo nano /etc/sysctl.d/60-oracle.conf
(Enter the following)
# Oracle 11g XE kernel parameters
fs.file-max=6815744
net.ipv4.ip_local_port_range=9000 65000
kernel.sem=250 32000 100 128
kernel.shmmax=536870912
(Save the file)
Note: kernel.shmmax = max possible value, e.g. size of physical RAM.
Verify: sudo cat /etc/sysctl.d/60-oracle.conf
Load new kernel parameters:
sudo service procps start
Verify:
sudo sysctl -q fs.file-max
-> fs.file-max = 6815744h4. A.5. Oracle Installation Directory
The current Oracle Installation Guide uses the same directory like in previous versions: /usr/lib/oracle/xe/app/oracle/product/11.2.0/server. However, the current Beta installation uses Oracle Flexible Architecture (OFA) and installs into /u01/app/oracle/product/11.2.0/xe. Due to size limitations of Oracle XE it may not be necessary to store the installation to a specific directory or separate volume, but it is possible:
Install Oracle XE to separate disk volume:
From the system console menu: System > Administration > Disk Utility
Select "ext3" filesystem for Oracle compatibility and specify a Volume label, e.g. Oracle.
Notice the device name e.g. /dev/sdb
Get the drive UUID:
sudo blkid
e.g. /dev/sdb: UUID="d19a2d8f-da43-4802-8bdb-0703c855e23a"
Modify /etc/fstab to automatically mount the volume at system startup:
sudo cp /etc/fstab /etc/fstab.original
sudo nano /etc/fstab
(Add the following, using determined UUID, for exmple)
UUID=d19a2d8f-da43-4802-8bdb-0703c855e23a /u01 ext3 defaults,errors=remount-ro 0 1
(Save the file)
Create the mount-point, mount the new volume and set ownership and privileges:
sudo mkdir /u01
sudo mount -a
sudo chown root:root /u01
sudo chmod 755 /u01
Verify:
df -h
or restart the systemYou can also install Oracle XE into a specific directory:
Create a symbolic link to store the installation into an existing directory, for instance:
sudo mkdir /home/oracle-xe
sudo ln -s /home/oracle-xe /u01h3. C) Oracle 11g XE Download and Installation
h4. C.1. Download and convert the Installer from Red Hat to Ubuntu
Please see section E.3. to download the Oracle 11gR2 XE installer.
Select the version listed for Linux x64.
sudo unzip linux.x64_11gR2_OracleXE.zip
sudo alien --to-deb --scripts oracle-xe-11.2.0-0.5.x86_64.rpm
(This may take a while)h4. C.2. Create a special chkconfig script
The Red Hat based installer of Oracle XE 11gR2 beta relies on +/sbin/chkconfig+, which is not used in Ubuntu. The chkconfig package available for the current version of Ubuntu produces errors and my not be safe to use. Below is a simple trick to get around the problem and install Oracle XE successfully:
Create /sbin/chconfig:
sudo nano /sbin/chkconfig
(Cut and paste the following)
#!/bin/bash
# Oracle 11gR2 XE installer chkconfig hack for Debian by Dude
file=/etc/init.d/oracle-xe
if [[ ! `tail -n1 $file | grep INIT` ]]; then
   echo >> $file
   echo '### BEGIN INIT INFO' >> $file
   echo '# Provides:             OracleXE' >> $file
   echo '# Required-Start:       $remote_fs $syslog' >> $file
   echo '# Required-Stop:        $remote_fs $syslog' >> $file
   echo '# Default-Start:        2 3 4 5' >> $file
   echo '# Default-Stop:         0 1 6' >> $file
   echo '# Short-Description:    Oracle 11g Express Edition' >> $file
   echo '### END INIT INFO' >> $file
fi
update-rc.d oracle-xe defaults 80 01
(Save the file)
Set appropriate execute privileges:
chmod 755 /sbin/chkconfig
Note: You should remove the /sbin/chkconfig file after successful installation of Oracle XE.
h4. C.3. Install and configure Oracle XE
sudo dpkg --install ./oracle-xe_11.2.0-1.5_amd64.deb
/etc/init.d/oracle-xe configure
(This will take a while)
Remove the /sbin/chkconfig script, which is no longer needed.
sudo rm /sbin/chkconfigh4. C.4. Relocate and Configure the Oracle user login
The Oracle XE installer specifies /u01/app/oracle as the login directory for the Oracle user. Although not really necessary, the following will relocate the Oracle user $HOME to a standard location and create standard /etc/skel login files:
Exit all Oracle user sessions:
sudo /etc/init.d/oracle-xe stop
sudo kill -9 `ps -ef | grep oracle | grep -v grep | awk '{print $2}'`
sudo userdel oracle
sudo useradd -s /bin/bash -G dba -g dba -m oracle
sudo passwd oracle

Edited by: Dude on May 25, Version B: various corrections. chkconfig package (A.2.) not required.

even though I am admin user.Admin user is a MS Windows term, that does not apply to Linux or Unix in the same fashion.
The configuration script tells you "You must be root user to run the configure script. Login as root user and
then run the configure script."
This is most likely correct because your account is not root and does not have UID 0. What you can do is to login as root e.g. sudo su -, as the message suggest, or use "sudo /etc/init.d/oracle-xe configure", provided your account is defined in the /etc/sudoers file to perform root/admin actions.
Btw, do not modify /etc/passwd and /etc/group to give you admin privileges or try to create a another root account under a different name. That's not the way it works and usually leads to nasty problems.

32 bit Oracle server installation on 64-bit Linux box

Certify - Product Version and Other Selections: Oracle Database - Enterprise Edition On Linux x86-64 (AMD64/EM64T)
General Notes For Oracle Database - Enterprise Edition On Linux x86-64 (AMD64/EM64T):
Processor Chip Information:
Linux x86-64, support on AMD64/EM64T and Intel Processor Chips that adhere to the x86-64 architecture with supported Linux releases.
"Running Oracle 32-bit on AMD64/EM64T (64-bit OS) is not supported . "
Oracle 32-bit running on AMD64/EM64T with a 32-bit OS is supported, refer to platform Linux x86 for more information on product availability.
Note: As Ivan confirmed EM64T is mark for Intel 64 (x86-64) processors.
Even the metalink Note: 182999.1 says...
"A 32-bit application will work on both a 32-bit and 64-bit O/S, whereas a 64-bit application will only work on a 64-bit O/S."
but the same articel says
"Note: These statements do not necessarily apply to Oracle on Windows O/S's, Itanium or AMD64/EM64T based Platforms. See Certify for specific information."
and then I got update from Support. Even they Say....
"No it is not suggested that you run Oracle at 32 bits for a Linux X86_64 platform. This would not be a good idea"
I guess I need to sit with my senior DBAs and SA tomorrow to find the path forward...
Thanks all.

Does Oracle give a damn about the Linux comunity?

I am the technical lead on a research project that will lead to a major
implimentation in the short term future. I pushed for Oracle since it
gives the best combination of performance, reliability, features and I
thought platform options. Linux is what our developers use as our
standard workstations. We do have a few holdouts still running Windows
but not many. We have had no problem obtaining client libs and Unix
ODBC drivers for Postgress, Sybase, MySQL and amazingly enough
even MS SQL Server. Oracle defies us. We have had to purchase
3rd party drivers to access Oracle DBs through Cold Fusion and PHP.
Now we cannot even aquire a simple SQL client so that we can create
and edit our schema's. A client readily availible in windows. I am
baffled. The client software exists, but only as part of a huge download.
To split it off to a seperate download would be trivial.
A simple fact in IT is that people tend to use what they are comfortable
with. That is why you see so many Access databases out there being
used for things Access should have NEVER been considered for. If you
make it too difficult to prototype in Oracle why are people going to
impliment in it? We have a liscenced copy of Oracle. Some basic VERY
basic support given to other platforms by Oracle and offered freely by
just about any other database out there would be a really nice sign from
Oracle that they don't consider the Linux comunity with hostility.
In other words I think it is imperitive for Oracle to provide some basic
ODBC drivers (reguardless of platform, for Oracle 7 under windows
we had to purchase 3rd party ODBC drivers since those provided were
so buggy as to be unusable.) SQL Clients and a little bit of documentation
on how to setup and configure them. Of the thousands of dollars probably
going to run into millions that this project is likely to send to Oracle I don't
think it is asking much to ask for these simple things to make it POSSIBLE
to use their product.
Writing our own SQL client and or downloading the entire Oracle demo
to aquire a client which may or may not continue to work after expiration.
Then having to visit machines scattered accross 3 square miles of compound.
Getting security clearence to get INTO those buildings. It's just running me
out of time and eating away at the funding for the project. If I had a simple
tarball or rpm then I could ssh into the machines that need the product,
install it and be done with it. If I had drivers that didn't steal from the projects
funding we would have happier clients. We are going head to head against
another group that has chosen MS SQL Server as thier backend and if thier
product reachs deployment before ours it will likely mean that what is used
from our project will be ported to MS SQL Server. I'd prefer that did not
happen. I am VERY frustrated however with the lack of response from Oracle.
I've left a couple messages in the forum, asked one of thier consultants
who was onsite. Generated several emails. No response. Because we
are "Linux" users I guess that means we should be able to decompile thier
installation scripts, pick out all of the dependancies for thier SQL client
and generate our own installation then debug it. It'd be nice if I had that
much time and confidence in the demo version that it won't time out and
stop the SQL Client. It'd be nice if an Oracle rep would even send me a
list of files needed for SQL + to install.
To let me know whether the SQL plus included with Oracles
demo code would continue to run after the 90 days or whatever the expiration
date is on thier demo package.
As an interm step we've ported the schema to Postgress and MySQL and
are doing development on those DBs since we can actully TALK to them.
I am very frustrated with Oracle right now. I know the companies goal
is to absorb us and we in a very M$ mannor use all Oracle products.
Simple fact is that won't happen. Oracle in my opinion makes not only
the best DB out there, Oracle has lead the market by creating most of
the major inovations in DBs. Oracle does data like no other. I'd like to
continue using Oracle. I'd like Oracle to pay a little attention and provide
the kinds of things their competitors provide. If this is the kind of service
we get when there is compitition what will happen if there were none?
Come on, providing ODBC, JDBC drivers and a SQL Client is not asking
for much!
I'd LOVE to hear someone from Oracle respond to this. I can be reached
by email at [email protected]

Well first of all if you go out to metalink and look under product lifestyle you will find a chart that tells you what platforms are certified. If you go out there today you will see oracle 9i is certified for red hat 7.1 but withdrawn for 7.0. 8.1.7 is certified for red hat 7.1 all the way down to 6.0. As for any Oracle version lower then that why would they certify it since they aren't completly supporting 8.1.6 and below any more. There is also a chart out there as to what is being supported regarding the oracle versions and and what type of support is available. As for downloading just the sql client. I have no trouble downloading the client for most platforms. I haven't tried to down load it for linux, but I use linux for the server not the client. Also you must realize that the version out there to be downloaded is the very latest and could be riddled with bugs. As I have found in the past. Next you mention that you are the lead in a research project for the short term future and that oracle should be making oracle 7 work with linux. Are you crazy? Oracle 7 is 5-7 years old, it is old and outdated, the only reason oracle extened service on that version is because some of the os's like hp-unix stated they will support their os's that run it for 1-2 more years so oracle matched it. They aren't solving any more bugs with oracle 7, so why in the world would they certify new platforms for a version they no longer support? Also if you are developing something new why would you not use the latest and greatest of all the apps you plan on using? I've been trying for 2 years for my company to get off of oracle 7 and from your email it seems that you are starting your company off using oracle with a version that is no longer supported. As for downloading a demo, I think you are just on the wrong part of the website because I've downloaded the server and client before when moving to linux from hp-unix and didn't have any problems with download. Now there were many days where the website was down, but I've gotten useto some parts of oracle's websites being down.

Oracle ASM on Windows

I think I may need some help getting the storage for my ASM right. I changed companies recently and the new place is a Windows house so the Oracle databases are all on 2008 R2 machines. I have run Oracle RAC on both physical and virtual before, but only in Linux/Unix environments (which so far I still prefer) so I'm still learning some of the ins and outs. This company is also looking at moving to RAC, so ASM is in the mix. To begin my testing, I have set up an ASM instance for a single host which will eventually become a development hub holding several databases. However, even before I've set up any databases, the host is locking up. I suspect it has something to do with the disk configuration in that while the lock ups have occurred while the vm is idling, several lock-ups have happened when I try to drop a disk from within the asmca utility. I followed the documentation that Oracle provided for Windows platforms, but this documentation of course does not offer insight into storage virtualization on vmware.
Here is my configuration:
VMware: vSphere 5.5
OS: Windows 2008 R2 Standard
Memory: 12G
Storage: OS: 60G; ASM: 20G, 5G, 5G
Oracle Grid: 11.2.0.4 (plus January 2014 CPU)
Oracle Database: 11.2.0.4 (plus January 2014 CPU)
Other details (maybe important, maybe not):
1) I have a large pages enabled
2) Disks are thin-provisioned. As a side-note, I've always thick-provisioned my ASM disks, but our Sr. IT admin has made a policy that all disks are to be thin-provisioned for efficiency. I'm not sure if this could cause an issue.
3) The 3 ASM disks are running using the Paravirtualized SCSI driver
4) The host also has an OEM 12c Agent installed and running.
I'm new to the Windows platform when it comes to Oracle (I've administered plenty of SQL Server DBs), but the lockups don't appear to be generating any kind of data to any logs.

I'll elaborate a bit more. The host is "locked up" in that you can ping it, but if you try to log in by RDP or through the vmware console, it doesn't generate your desktop. Also, whatever is happening on the server is keeping the agent, listener, etc, from reporting to OEM. Lastly, if an RDP session is open, then you'll get the "disconnected from session... attempting to reconnect... " message. The only way to get it out of this state is to tell the hypervisor to reset the system.
Now, as for logs, there is nothing in the asm alert log. The most recent trace file generated is from an rbal event around the time of the lockup, but there aren't any similar traces during the others.
I've checked the windows event logs for errors as well. In the application event log, there was an agent fault during the most recent lock up, but there wasn't one for the previous occurrences. I'm thinking it's more effect, than cause. Nothing listed in the server logs. I have asked the sysadmins to look at the vmware logs, but they're a little challenged in that area and I'm finding I need to provide guidance on issues.

Is Oracle slow???

Hi,
I am in a typical situation...as an oracle dba I need to explain the the difference between Oracle and SQL Server to management..
Oracle:
My question is we have one Oracle 10g 10.2.0.1 instance running on HP-UX 11.21 itanium server...
I have written RMAN online Backup to take backup with compression...thati is the script that what i am using..Daily night there is no load, at that time backup is occuring...
crosscheck backup;
backup as compressed backupset database;
sql 'alter system switch logfile';
backup as compressed backupset archivelog all;
backup as compressed backupset current controlfile;
=========================
The above backup took 1 hour 20 mins to complete. After moving the above backupsets to TEST Machine.... It took 2 hours 30 Mins to clone entire database....
So finaly...
For taking Backup = 1 hour 20 Mins
For Cloning = 2 Hour 30 Mins
We have important 2 tablespaces for java based application....
DATA_TBS used size = 3.5 GB
INDEX_TBS used size = 4 GB
In Oracle..For Cloning..I move all RMAN backupsets to TEST Machine and clone using
run
restore database;
revover database;
alter database open resetlogs;
================================
This is regarding SQL Server 2005 on windows 2003 Machine with same type of hardware and memory and processor speed with same type of hard disks.
Here same Java Application database ( Same tables ) which is on SQL Server....
For taking Backup = 10 Mins
For Restore backup to other machine = 20 Mins
Here for Backup...right click on database and take backup..for restore also..right click and restore...everything is GUI....
============================================
Why this much difference between Oracle and SQL Server....Management is asking..
Is Oracle slow???????
If it is slow...why cant we migrate our databases to SQL Server like that they are asking....
Friends...what I can say...as normal Oracle DBAs does...same thing I am doing regading RMAN Backup and Restore...
But for taking Backup and Clone in Oracle it is taking much time compared to SQL Server
what might bethe reasons?????
Please help me in this regard???
Keep in mind that...
In both machines where we are clong..both are with same hardware and same memory and same processors and same hard disk speed...but why Oracle is slow for backup and cloning...how can i explain these things to management??????please sched some light on this.......

Deepa_t,
So what we have here is
- one server, 50 percent of RAM grabbed by SGA.
This is the typical symptom of resolving performance problems by throwing memory at the problem. Actually this can have a negative impact on performance.
- All data files and logfiles on one disk. One shouldn't do that, as it creates an I/O bottleneck. Must I assume the disk is RAID-5 too?
- Default backup strategy (rman copy) not being followed
- Default backup being use: so unlimited backup set size, unlimited backup piece size. This will result in RMAN opening as much datafiles as possible, and reading them all at once, simultaneosly, consequently creating an I/O bottleneck
- Where is the backup going to? To the Flash Recovery Area? On that same disk?
To $ORACLE_HOME/dbs? On that same disk?
Then we have the usual stupidity of management comparing apples and pears.
Oracle and Sqlserver are completely different products!
You have an untuned RMAN backup, and probably you are flooding that single disk with I/O requests, and the only thing managers do, knowing nothing about databases. knowing nothing about Oracle, is take their watches, and say 'Hey, it is slower, how come?'
Your question is like a bad Homer Simpson movie. I can even hear Homer uttering this last question!
Didn't they allow untrained staff to set up a suboptimal configuration?
And now untrained staff should explain?
First thing you need to do is to make you sure you stop flooding the disk with IO requests. You need to use filesperset settings, maxpiecesize settings etc.

Install PeopleTools 8.53 with Linux Issue: Client Windows and Server Linux

Folks,
Hello. I am installing PeopleTools 8.53 Internet Architecture. Database Server is Oracle Dabase 11gR1. OS is Oracle Linux 5. I have installed JDK7, WebLogic 10.3.6, Tuxedo 11gR1 and PeopleTools 8.53 successfully into Oracle Linux 5.
Now, I am setting up PeopleTools8.53 Database. Because the Install Wizard has problem, I set up PeopleTools 8.53 Database manually using Oracle starter database instance named PT853. We need to run Data Mover script in a Windows Client machine to populate PeopleSoft Database instance in Linux Sever machine.
Let's assume:
VM1: Server machine - Oracle Linux 5
VM2: Client machine - Windows XP
Nicolas has this tutorial:
http://gasparotto.blogspot.com/2008/01/on-peoplesoft-road-peoplesoft-database_10.html
From step 15 to step 23, Nicolas does not explain how to connect VM2(client) with VM1(server) and load data from VM2 to VM1.
My questions are:
First, do we need to install PeopleTools 8.53 Windows version into the Client machine Windows XP while installing PeopleTools 8.53 Linux version in the Server machine Oracle Linux 5 ?
Second, how to connect VM2 with VM1 and then load data from VM2 to VM1 ?
Thanks.

So if I understand correctly, you have already created the oracle instance in the Linux machine. Then there is no need to install the Tools again in the Linux machine unless you want to run data mover at Linux.
You can just install the tools and oracle client in windows and load the data by running the data mover from windows. Connection happens through Oracle Client using TNS.
Steps involved are
1. Creating the database using createdb10.sql or otherwise (you have already done this)
2. Run utlspace.sql
3. Run dbowner.sql
4. Run ptddl.sql - considering that you are just installing a Tools database and not any application database
5. Run psadmin.sql
6. Run psroles.sql
7. Run connect.sql
Create the data load dms file by using DBSETUP in data mover
Run the created script and load the data
This information is available in any peopletools installation doc
Hope this helps

Install PT8.53 with Linux Issue: Windows NetMgr and Linux NetMgr

Folks,
Hello. I am installing PeopleTools 8.53 Internet Architecture. Database Server is Oracle Dabase 11gR1. OS is Oracle Linux 5. I have installed JDK7, WebLogic 10.3.6, Tuxedo 11gR1 and PeopleTools 8.53 successfully into Oracle Linux 5.
I have been setting up PeopleTools8.53 Database. Because the Install Wizard has problem, I set up PeopleTools 8.53 Database manually using Oracle starter database instance PT853. I have run the following scripts:
1) utlspace.sql
2) dbowner.sql
3) ptddl.sql
4) psadmin.sql
5) psroles.sql
6) connect.sql
Then, we need to run Data Mover script in a Windows Client machine to populate PeopleTools Database instance PT853 in Linux Sever machine. I have installed Oracle Database 11gR2 client for 32-bit Windows in my 64-bit Windows XP Virtual Machine. Now, I confront 2 VMs' connection issue as below:
In Linux Server Machine Net Manager:
Service Name: PT853
Connection Type: Database Default
Protocol" TCP/IP
Host Name: localhost.localdomain
Port Name: 1521
Listener: LISTENER
Protocol: TCP/IP
Host: localhost.localdomain
Port: 1521
I test the Service PT853 using UserID "SYSADM" and Password "SYSADM". The connection is successful.
In Windows Client machine, the information in Net Manager is the same, but the connection is not successful. Its details are as below:
Net Service Name: PT853
Protocol: TCP/IP
Host name of Database Machine: localhost.localdomain
Port Number: 1521
Database Service Name: PT853
Connection Type: Database Default
I test the Service using UserID "SYSADM" and Password "SYSADM" that are the same with Linux, but get this error: TNS: listener does not currently know of service requested in connect descriptor.
My questions are:
Do we need to do something to connect Windows XP with Linux at first ? If yes, How to do it ? If no, how to solve the above issue ?
Thanks.

Folks,
Hello. Thanks a lot for replying.
Regarding PeopleSoft networking, I have done Configuration Manager to enable Data Mover and Application Designer to login into Database Instance PT853.
Regarding 2 Virtual Machines (Windows XP and Oracle Linux 5) connects with each other, I have done the following:
First, I follow this tutorial http://www.vmware.com/support/ws5/doc/ws_devices_serial_2vms.html to configure 2 VMs for Windows 7 Host.
Second, in Windows XP Oracle Database Client Install Directory, the file "tnsnames.ora" has one entry that is the Service Name in Net Manager. In Linux Oracle Database Server install directory, the file "tnsnames.ora" has no entries because I installed Oracle Database Server with the starter Database instance PT853.
I have tried to test 2 VMs in the way as below:
In Linux, [user@localhost ~]$ping WindowsHostName
Its output: unknown host WindowsHostName
In Windows XP Command Prompt:
C:\ping localhost.localdomain
Its output: pinging localhost.localdomain 127.0.0.1 with 32 bytes of data...
Reply from 127.0.0.1: bytes=32 time=2ms, TTL=128
It replies a few times and then disconnected by itself. It seems that Windows XP is pinging itself and not Linux Server. The hostname of Linux Server is "localhost.localdomain" as well. It's a kind of confusing to me.
From the above infromation, we can see 2 VMs cannot connect with each other. Net Manager in Windows XP Oracle Client cannot connect its Service PT853.
I don't understand how to connect Oracle Client in Windows with Oracle Database Server in Linux. Can any folk help to solve this issue ?
Very grateful in advanced.

Is ORACLE slower on Windows then on Linux ?
