Memory_targetパラメータの使用
よろしくお願いします。
OS：Windows2008 R2 Enterprise
DB:Oracle 11g R2 Enterprise Edition
インスタンスのセットアップが完了し、
パラメータの設定をしています。
11gからの機能である「memory_target」を使用し、
その上限を2GBに設定しました。
また「sga_max_size」など旧パラメータをAlter System文で「0」に
明示的に設定しました。
ところが、インスタンスを起動して値を見ると
「sga_max_size」に値が入ってしまいます。
※数回試しましたが結果は同じでした。
当初は、memory_target、memory_max_target以外の以下のメモリ関連の
パラメータは「0」になるものと想定していました。
NAME TYPE VALUE
sga_max_size big integer 1228M
sga_target big integer 0
memory_max_target big integer 2G
memory_target big integer 2G
pga_aggregate_target big integer 0
これは設定としては正しいのでしょうか？。
それとも手順に漏れがある疑いがあるでしょうか・・？。
皆様有難うございます。
お手数をおかけします。
バージョンですが、64bit環境だと思います。

TNS for 64-bit Windows: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
実はご指摘頂いたようなマニュアルベースでの記述を探しています。
結局、設定が正しいのか判断をしたいのですが、その根拠が見つけられずにおります。
下記の怪しいブログなどは見つけたのですが、結局sga_maxsizeは、memory_target値の60%ほどを
割り当てられるのは、事実として間違いなさそうは思います。

Memory_max_target and memory_target on 11.2
Hi gurus,
after an upgrade from DBMS10g to 11.2 our DBA changed manually parameters about memory in the following way:
*.db_cache_size=2113929216
*.hash_area_size=101310720
*.java_pool_size=83886080
*.log_buffer=5097152
*.memory_target=0
*.pga_aggregate_target=838860800
*.sga_max_size=12884901888
*.sga_target=0
*.shared_pool_reserved_size=61331648
*.shared_pool_size=1677721600
Is this the right way to configuree parameters on 11g? or is better to set only the .memory_max_target and memory_target and allow Oracle to manage dynamically the other memory size?
Thanks in advance.Hi DDF,
It is simple to use SGA_TARGET with SGA_MAX_SIZE (Need to allocate PGA) or Memory_target witn memory_max_target (not need to define PGA).
But make sure your applications are running ok with that setup. Sometimes you may need to define other memory parameters.
Cheers

Memory_target and memory usage reported by windows taskmanager
Hi,
shouldn't Oracle 11g limit the amount of used memory (reported by windows taskmanager for process oracle.exe) to the value of "memory_target" (which means using automatic memory management)? My database running on Windows 2003 R2 32bit (RAC) is constantly consuming more and more memory (limited to 500MB, currently using 741MB), until it reaches the limit of 1.7GB, which one process can use. After this the database fails.
The database is hosting three very simple applications, no challenge for Oracle. :-)
Thanks in advance,
Frankshort update: both database instances are configured for 500MB "memory_target" and currently one database is using 877MB virtual memory and the other one 784MB of virtual memory (according to windows taskmanager, process oracle.exe). One of these instances is a recovery catalog, doing nothing at all (at the moment).
I'm really worried where all the memory is going to! -
Error changing value of memory_target in 11g
Hello -
I am getting this error:
SQL> alter system set memory_target=250M sid='m433d1';
alter system set memory_target=250M sid='m433d1'
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-00846: could not shrink MEMORY_TARGET to specified value
Here are the current memory values:
m433d1.__db_cache_size=96468992 = 92M
m433d1.__java_pool_size=4194304 = 4M
m433d1.__large_pool_size=8388608 = 8M
m433d1.__shared_pool_size=184549376 = 176
pga = 108
SQL> show parameter pga_aggregate_target;
NAME TYPE VALUE
pga_aggregate_target big integer 12M
SQL> show parameter sga_target
NAME TYPE VALUE
sga_target big integer 200M
Why would I not be able to set to 250M, if the pga + sga = 212M? The individual componts of SGA + PGA = 284M. Therefore, it allows me to resize to resize with 275M, but not 272M:
SQL> alter system set memory_target=275M sid='m433d1';
System altered.
SQL> alter system set memory_target=272M sid='m433d1';
alter system set memory_target=272M sid='m433d1'
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-00846: could not shrink MEMORY_TARGET to specified value
Any ideas are greatly appreciated!
Thanks,

==========
I understand that these values were set explicitly.
You can see the values of db_cache_size and shared_pool itself totals to 268M
Since these values are set explicitly, then you cannot give the value for memory_target to a lower value.
OR
set all other component values to 0 and set memory_target.

Oracle XE 11gR2 - smallest (I mean really small) memory_target allowed?
I'm installing Oracle XE 11gR2 on a RHEL (OK, it's really CentOS) 5.6 VPS that has 512MB of memory. That is the minimum XE will install on.
It's just for my personal use, testing, etc.
I've added a swapfile that gives me more memory - a total of 1GB. Fortunately, the CPU and disk are very fast.
With XE up and running, I still show a good amount of memory (Buffers in free -m shows 361M free, and only 54M of swap is in use).
My question...how low can I set the XE memory_target? By default it's set to 196M. I'm wondering if I could crank that down a bit...perhaps 96M? Is there a "don't go below" minimum?
As I understand it, I can set MEMORY_TARGET and MEMORY_MAX_TARGET the same...setting MEMORY_MAX_TARGET higher would just give me the ability to increase MEMORY_TARGET without having to bounce in the instance. In my case (single user, lab instance, etc.) I don't think that matters.Well, I think I just answered my own question :-)

db 11.2.0.2 rac GI 11.2.0.2thanks for the links,
"When using AMM (by setting memory_target, and/or sga_target, the values for the “traditional” pool parameters (db_cache_size, shared_pool_size, &c) are not ignored. Rather, they will specify the minimum size that Oracle will always maintain for each sub-area in the SGA.
so that means PGA wont grow more than 500MB and SGA be set to minimum of 4.5GB?
actually if you carefully read the above comment it doesnt mentiond sga_max_size it only says traditional pools such as db_cache_size etc...
does this also include sga_max_size?
I had a look at the other link to a thread but the question is slightly diffrent, they are discussing relation of sga_target to memory_target, I am intrested to know about sga_nax_size inrelation to memory_target -
Oracle 11g memory_target best practices
Hi expert.
I'll use memory_target in my oracle 11g enviroment. There is a best practices, or formula, for to choose my memory_target?
There is a memory_target limit? (for example 128gb)
Many thanksThanks for the replies.
I could like know if there are some criteria, or formula, to a correct memory_target set.
I'm reading the file OracleOLTPonDellEqualLogicPS60x0.pdf

that explain the best practices for an Oracle RAC 11g on Dell Server. About the Tuning Parameter I don't undestand very well what's the criteria for to choose the MEMORY_TARGET between 32,40 or 48GB
Maybe choose what's the correct memory value for my server? I've an machine with X gb of RAM that I can allocate for an oracle istance. There is a fisical limit MEMORY_TARGET?
Thanks for all suggest.

Changing MEMORY_TARGET: help please
Hi,
I have Oracle 11g installed in a VMWare image(linux). The current setting of 1G for the memory (I read it in the init.ora, parameter memory_target=1G) is too much for my PC.
I set memory_target parameter=300M in init.ora but this does not seam to work.
Note, currently the instance cannot be started, because I reduced the Virtual Memory setting in the VMWare options,
so I cannot use: ALTER SYSTEM SET MEMORY_TARGET=300M SCOPE=SPFILE;
Is there a way to change this before starting the database?
Thanks much.Hi,
thanks for the tip.
I must have done something wrong, at step 5 the guides tells to change memory_max_target
ALTER SYSTEM SET MEMORY_MAX_TARGET = nM SCOPE = SPFILE;
(I put 400M), then the manual says to restart. But actually the db is not restarting complaining that
the memory_target is bigger the memory_max_target (of course!).
How can I recover this situation? How can I change now memory_target?
Thanks much. -

Thanks,Hi Fran,
I had red the documents . But i have few doubts, could you please guide me
To fix this issue:
1- Apply Patch 8813366 located in:
https://updates.oracle.com/download/8813366.html
or
2- Upgrade to 11.2.0.1 and apply 11.2.0.2 patchset which has the fix for bug 8813366. --- currently MY DB IN 11.2.0.3
or
3-WORKAROUND:
Reduce the number of shared pool subpools by setting the init.ora parameter
"_kghdsidx_count"=2
or reduce granule size with init.ora parameter:
"_ksmg_granule_size"=16777216
NOTE: These require an outage of the database
Is there any Permannet solution ? Is this issue will effect the performance? -
Hey to all of you I’ve install oracle 11g on windows server 2003 enterprise edition with patch. Now I want to use the feature of automatic tuning of SGA and PGA by setting memory_max_target, memory_target . I’ve 4GB ram and I wanted to allocate memory_max_target 3Gb could I do that on window 32bit with 8k block size of oracle. Note I’ve used address space for oracle .exe 3Gb switch now if I issue this
alter system set memory_max_target = 3G scope=spfile;
alter system set memory_target = 3G scope = spfile;
what do yoy think what would happened plz guide me if I’m going wrong somethingI’ve complete idea of AWE switch in Boot ini. I’ve read a document 60 pages last night. Anyway I’m going to install 11g to my test server with same specification and I tried this and inform you. After reading AWE I think it should work. I checked your profile and happy to see you. You are as smart as you are in oracle concept. Impressive personality. you can check my profile/adeel rest address is same. But I suggestion don’t look me becoz I’m as bad as I’m in oracle thanks for help brother take care

ORA 04030 Out of process memory error
Dear experts,
I know there are multiple discussions around this error and I have been reading through most of them in the past one week or so, but looks like we are running out of options or are missing the color altogether. Ok, we are getting ORA-04030 - out of process memory while allocating....while one of our batch process runs in the night. It simply tries to insert/update to a table. Our installation is 11.2.0.1.0 with no RAC configuration and on 64-bit AIX having 6 cores, 12 CPUs and 16 GB memory.
We have checked the Workarea_Size_Policy is set to be as Auto so Oracle decides how much memory to allocate to PGA automatically on run-time based on the demand. And based on the AWR report it doesnt look like we are anywhere near the country having a PGA-deficit!! I am attaching the AWR report in a word document here for your reference.
Also attached below are the configurations and the ulimit values.
IKBTRN1> show parameter workarea;
NAME TYPE VALUE
workarea_size_policy string AUTO
oraipeikbtrn1:/home/oracle-> ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 4194304
memory(kbytes) unlimited
coredump(blocks) unlimited
nofiles(descriptors) unlimited
threads(per process) unlimited
processes(per user) unlimited
Now, nothing seems to have contributed to the out of process memory issue from Oracle standpoint. I would be happy to be proved wrong here, if I am wrong.
So, whats going wrong here? A possible memory leak which we cannot zero down to, a OS memory limit or something else?
Seeking expert's advise on this, and also sincerely appreciate your time in looking at this.
Thanks.
P.S - I am pasting the whole AWR report since there is no 'upload file' option here that I can see.

I couldnt add the rest of the report here since it is telling me I have exceeded 30000 characters. If you want to see the full report, please email me at [email protected]Unless your database is strictly a DSS-type of database, your AWR report exposes loads of issues with it. And I think none of the time during the AWR window was spent on database. Look at the DB time (with all those multi cores) compared with the elapsed time of the AWR.
As you are on 11g, why not make use of MEMORY_TARGET (a single parameter to manage both SGA and PGA)? If you are already on it, ignore this as I can't see it anywhere. If not, get rid of SGA_TARGET and PGA_AGGREGATE_TARGET and replace it with a single MEMORY_TARGET parameter. However you may have a minimum threshold set for different SGA pools so that they won't shrink beyond that point.
Having said that, setting MEMORY_TARGET is not a guarantee to avoid ORA-4030. Just a single bad PL/SQL code could go and exploit the untunable part of your process memory and even go and blow up the physical memory. If you are using FORALL and BULK load, see if you can cut it down into few chunks rather than running as a single process.
What does your V$PGASTAT say? -
Hi everybody!
I have a problem. Some weeks ago I opened a post related to this issue. We have two dataguards with dataguard broker. One of them is resync (thanks to mseberg and this forum) and now I have problems with the other.
Once I have learned how to configure and start/stop dataguard broker, I have a more basic problem, which is to resync it. I follow a process, where I backup the primary with RMAN, I copy the rman files to the other server with the controlfile, at once, I recover with rman again.
The problem is that it is too big, 2 hours for backing it up more or less, and when I restore it, no archivelog list appears being syncronized.
I have followed the same process than the other one and I can't resync it. I think there is something at my params or something new at 11g version...

This document outlines instructions how to install Oracle XE under Ubuntu 11.10.
Ubuntu or Debian based Linux is not on the list of supported operation systems according to the Oracle documentation at http://download.oracle.com/docs/cd/E17781_01/install.112/e18802/toc.htm. You may want to consider virtualization software like Oracle Virtualbox and install Oracle Enterprise Linux as a free and professional alternative to installing XE under Ubuntu. You can also download pre-build virtual machines that include Oracle XE. You can browse http://otn.oracle.com/community/developer-vm for more information.

h4. 11) History
h4. 12) References
h2. 1) Install Linux Ubuntu
The following assumes you have installed Ubuntu 11.10 Desktop Edition for AMD 64-bit, or upgraded from a previous version. Keep in mind that Oracle 11gR2 Express Edition is only available for 64-bit architecture. It is not necessarily a requirement, but I would not bother to install Oracle 11gR2 XE on a system with less than 2 GB of RAM installed. You can download Ubuntu for free at: http://www.ubuntu.com/download/ubuntu and install it using the default settings provided.
You can apply the latest OS patch-sets by clicking the power button icon in the upper right hand corner of the screen and selecting "Updates available..."
h2. 2) Remote Terminal
You will need command line access to perform the installation tasks. Select the top "Dash Home" button of the Unity toolbar and enter the word "terminal", or use CTRL-ALT-t. If you prefer to open a remote terminal session use SSH. Ubuntu does not come with a secure shell login by default. To install it, use the following command:
sudo apt-get install openssh-serverYou cannot login as root unless you set a root password using the "sudo passwd root" command. However, you can get root user access using the "sudo" command, which requires only to re-enter the password of your personal account. Access to "sudo" is controlled by the /etc/sudoers file.
The best way to establish a remote command line session as root is to login with your personal account, e.g.: ssh [email protected], and then type "sudo su -" to become root, or use "sudo <command>" to execute individual commands. If your account does not have "sudo" access you can login as root using "su - root", but will need to know the root password.
h2. 3) Install Additional Software
Oracle 11g Express Edition requires additional software that is not installed by default:
sudo apt-get install alien libaio1 unixodbch2. 4) Managing Swap Space
Oracle demands that the minimum swap space for Oracle Database XE is 2 GB (2095100 KB) or twice the size of RAM, whichever is lesser. Enter the following shell command to verify your swap space:
cat /proc/meminfo | grep -i swap
SwapCached: 0 kB
SwapTotal: 2095100 kB
SwapFree: 2095100 kBYou can increase available swap space by using a swap file as long as disk space permits. The advantage of a swap file versus a swap partition is flexible space management because you can add or delete swap space on demand as necessary. The following will create and enable an additional 1 GB swap file at system startup, located in the /home directory:
Login as root:
sudo su -Enter the following commands:
dd if=/dev/zero of=/home/swapfile bs=1024 count=1048576
mkswap /home/swapfile
swapon /home/swapfile
swapon -aCreate a backup of the original "fstab" file and add the new swap file:
cp /etc/fstab /etc/fstab.backup_`date +%N`
echo '/home/swapfile swap swap defaults 0 0' >> /etc/fstabExit from root and verify the new swap space:
exit
swapon -s
Filename Type Size Used Priority
/dev/sda5 partition 2095100 0 -1
/home/swapfile file 1048572 0 -2Swap space is not a substitute for installed RAM. Swap space is a safeguard that allows the system to move idle processes to disk before the OOM killer will begin to terminate processes in order to free up enough real memory to keep the system operational. The general rule for sizing the swap space depends on the size of installed RAM. If your system has less then 4 GB of RAM the swap space should usually be at least twice this size. If you have more than 8 GB of RAM installed you may consider to use an equal size as swap space. The more RAM you have installed, the less likely you are going to run into memory starvation, and the less likely you are going to need swap space, unless you have a bad process.
h2. 5) Modify Kernel Parameters
Oracle 11gR2 Express Edition requires the following Kernel parameters. Enter the commands exactly as shown:
Login as root:
sudo su -Cut & paste the following directly into a command shell (not a text editor):
cat > /etc/sysctl.d/60-oracle.conf <<-EOF
# Oracle 11g XE kernel parameters
fs.file-max=6815744
net.ipv4.ip_local_port_range=9000 65500
kernel.sem=250 32000 100 128
# kernel.shmmax=429496729
kernel.shmmax=107374183
EOFLoad and verify the new kernel parameters:
service procps start
sudo sysctl -q fs.file-max
sudo sysctl -q kernel.shmmax
sudo sysctl -q net.ipv4.ip_local_port_range
sudo sysctl -q kernel.sem The SHMMAX kernel parameter defines the upper memory limit of a process. It is a safeguard to stop a bad process from using all memory and causing RAM starvation. The Linux default is 32 MB. The official Oracle XE installation documentation suggests a value of 4 GB -1 bytes (429496729). Since Oracle 11g XE has a 1 GB memory limit, a smaller footprint will be a better safeguard for the complete system. Setting the SHMMAX parameter to 107374183 will be sufficient.
h2. 6) Oracle Home Directory
At the time of this writing, Enterprise Linux 6 is not supported for Oracle database yet. It is therefore not possible to confirm Oracle ext4 filesystem compatibility, which is default in Ubuntu 11. According to various information, ext4 may cause a performance problem for Oracle 11g database. The following will show you how to add a ext3 partition to your existing setup.
h3. 6.a) Resize the Root Partition
Provided you have sufficient free disk space, you should be able to resize the root partition to create an extra ext3 filesystem. Considering the 11 GB user datafile limit of the Express Edition, 18 GB should be more than enough.
You can use the free Gparted Live CD to shrink your startup volume. Gparted downloads are available at http://sourceforge.net/projects/gparted/files/gparted-live-stable. When burning the CD, pay attention to burn the raw .iso image and not the possibly "mounted" image. If you are using a virtual machine like Oracle Virtualbox, you can mount the .iso image directly. There are going to be a few prompts when the system starts from the CD, but you can press Return to accept the defaults.
When the Gparted window appears:
- Select your ext4 root partition, usually /dev/sda1
- Select the "Resize/Move" button from the toolbar.
- Enter 18000 into the "Free space following" field and press the Return key.
Be careful not not change the start of the partition!
- Click the "Resize/Move" of the dialog and then then the "Apply" toolbar button.
The process may take several minutes - do not abandon it!
- Select the new unallocated free space of ~ 18 GB and push the "New" button.
- Set the file system to "ext3" and label it "oraclexe" and click the "Add" button.
Be sure to label it oraclexe, otherwise the follow-up instructions will fail.
- Finally select "Apply from the toolbar to apply the changes.
- Quit "Gparted", select "Exit" from the desktop and choose "Reboot" to restart the system.
{code}
After the system has restarted, open a terminal command shell.
Login as root:
{code}
sudo su -
{code}
Backup "fstab" and add the UUID of the partition. The "tr" command remove the quotes:
{code}
cp /etc/fstab /etc/fstab_`date +%N`
uuid=`blkid | grep oraclexe | awk '{print $3}'`
uuid=`echo $uuid | tr -d '\042'`
echo $uuid
echo "$uuid /u01 ext3 errors=remount-ro 0 1" >> /etc/fstab
{code}
The UUID is a unique number and should look similar to:
{code}
UUID=d1db753e-b5dd-4a4c-a61e-259c69867b58
{code}
Restart the system:
{code}
reboot
{code}
Verify the success:
{code}
df -h /u01
{code}
h3. 6.b) Setup External Storage
If you prefer to setup an external drive to install Oracle XE, beware that it can be a fatal mistake to make an entry in /etc/fstab to automount your external storage device. An unavailable device in /etc/fstab will prevent a system startup and prompt for appropriate actions at the console.
The following is an example of how to prepare an external storage device to be used for Oracle 11g, including a script to automatically mount an external drive at system startup without the disadvantages of /etc/fstab. The script will also take into consideration that a device name might shift if you attach additional devices.
To find out which USB devices are connected:
{code}
sudo parted -l
{code}
Look for the device that matches your USB storage. For example: /dev/sdb1
{code}
Model: USB 2.0 Flash Disk (scsi)
Disk /dev/sdb: 2064MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 20.5kB 1929MB 1929MB hfs+ mystick
{code}
Initialize the device using ext3 filesystem - this will erase all data. The "-c" option will check for bad blocks (read-only), "-L" is the volume label:
{code}
sudo umount /dev/sdb1
sudo mkfs.ext3 -c -L oraclexe /dev/sdb1
{code}
Install the pmount distribution package:
{code}
sudo apt-get install pmount
{code}
Login as root:
{code}
sudo su -
{code}
Cut & paste the following into the command prompt (not a text editor):
{code}
cat > /etc/init.d/oracle-mount <<-EOF
#! /bin/sh
# /etc/init.d/oracle-mount
VOL_UUID=alphanumeric

if [ "\`/usr/bin/pmount | /bin/grep \$VOL_DEVICE\`" ]; then
echo "Error unmounting \$VOL_DEVICE"
else
rm -f \$VOL_SYMLINK
fi
echo "Usage: /etc/init.d/oracle-u01 {start|stop}"
exit 1

{code}
Install the oracle-mount init script:
{code}
chmod 755 /etc/init.d/oracle-mount
update-rc.d oracle-mount defaults 01 99
{code}
Get the UUID of the volume "oraclexe" and update the VOL_UUID in the init script accordingly:
{code}
uuid=`blkid | grep oraclexe | awk '{print $3}'`
echo $uuid
sed -i "s/^VOL_UUID=.*/VOL_$uuid/g" /etc/init.d/oracle-mount
{code}
The UUID of your device will be a unique number, but should be similar to:
{code}
UUID="3f5e9963-b328-49f3-b3e8-a3561ae34106"
{code}
Logout of root and test the init script:
{code}
exit
sudo /etc/init.d/oracle-mount stop

h2. 7) ORA-00845: MEMORY_TARGET
Oracle 11gR2 XE under Ubuntu 11.10 will result in "ORA-00845: MEMORY_TARGET not support on this system" either at Oracle database startup or during the initial installation. Ubuntu 11.10 uses a new version of the "systemd" system and session manager and has migrated away from /dev/shm and other common directories in favor of /run.
There are several ways how to address the problem. You can either enable /dev/shm shared memory, or change the default memory management of Oracle 11g from AMM (Automatic Memory Management) to ASMM (Automatic Shared Memory Management) as it was in used the previous 10g version. Since AMM is one of the new features of 11g, the following will show you how to make to make AMM work.
Login as root:
{code}
sudo su -
{code}
Cut & paste the following into the command prompt (not a text editor):
{code}

{code}
Restart the system:
{code}

{code}
The upper limit of shared memory under Linux is set to 50 % of the installed RAM by default. If your system has less than 2 GB of RAM installed, there is still a chance to run into ORA-00845 error if your shared memory is used by other software.
The verify available shared memory, type the following commands:
{code}
sudo df -h /run/shm
{code}
h2. 8) Installing Oracle 11gR2 Express Edition
The final release version of Oracle 11gR2 Express Edition can be downloaded for free at http://otn.oracle.com/database/express-edition/downloads. The software should automatically downloaded into the "Downloads" folder of your home directory.
Enter the following commands to unpack the installer:
{code}
cd ~/Downloads
unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip
rm oracle-xe-11.2.0-1.0.x86_64.rpm.zip
{code}
The Debian Linux based package management of Ubuntu is not compatible with the Red Hat package manager. The Oracle installer needs to be converted using the following commands:
{code}
cd ~/Downloads/Disk1
sudo alien --to-deb --scripts oracle-xe-11.2.0-1.0.x86_64.rpm
(This may take a few minutes)
rm oracle-xe-11.2.0-1.0.x86_64.rpm
{code}
The following needs to be set for compatibility:
{code}
sudo ln -s /usr/bin/awk /bin/awk
sudo mkdir /var/lock/subsys
{code}
Ubuntu uses different tools to manage services and system startup scripts. The "chkconfig" tool required by the Oracle installer is not available in Ubuntu. The following will create a file to simulate the "chkconfig" tool.
Login as root:
{code}
sudo su -
{code}
Copy & paste the following *directly* into the command prompt to create a file:
{code}
cat > /sbin/chkconfig <<-EOF
#!/bin/bash
# Oracle 11gR2 XE installer chkconfig hack for Debian based Linux (by dude)
# Only run once.
echo "Simulating /sbin/chkconfig..."

Install Oracle 11gR2 Express Edition entering the following commands:
{code}
cd ~/Downloads/Disk1
sudo dpkg --install ./oracle-xe_11.2.0-2_amd64.deb
(This may take a couple of minutes)
{code}
Run the configuration script to create (clone) the database and follow the screen. Accept the default answers, including "y" to startup the database automatically, or modify as required.
{code}
sudo /etc/init.d/oracle-xe configure
(This can take a few minutes - the installation completed successfully.)
{code}
To verify success, the procedure should end showing:
{code}
Starting Oracle Net Listener...Done
Configuring database...Done
Starting Oracle Database 11g Express Edition instance...Done
Installation completed successfully.
{code}
Set a password for the Oracle account:
{code}
sudo passwd oracle
{code}
h2. 9) Post-Installation
In order to use sqlplus and other tools, the Oracle account requires specific environment variables. The following will set these variables automatically at every Oracle login:
Login as the Oracle user:
{code}
su - oracle
{code}
Copy the default account skeleton files and add the Oracle env script to .profile:
{code}
cp /etc/skel/.bash_logout ./
cp /etc/skel/.bashrc ./
cp /etc/skel/.profile ./
echo "" >>./.profile
echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >>./.profile
{code}
By default, the Oracle Database XE graphical user interface is only available at the local server, but not remotely. The following will enable remote logins:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and execute the following:
{code}
sqlplus / as sysdba
SQL> EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
exit
{code}
See http://download.oracle.com/docs/cd/E17781_01/admin.112/e18585/toc.htm for more information.
h3. a) Unity desktop configurations
The Oracle XE menu under the previous Gnome Classic desktop shows several useful scripts to backup the database, start and stop the database, etc. Under the Unity based desktop this menu is not available. You can either switch to the Gnome Classic desktop as outlined in chapter 2, or perform the following steps to modify and copy the scripts as outlined below. The start and stop database scripts will also be modified to perform a progress feedback.
Login as user root:
{code}
sudo su -
{code}
Convert desktop files:
{code}
cd /usr/share/applications
sed -i 's/Categories.*/Categories=Database;Office;Development;/g' oraclexe*
sed -i 's/MultipleArgs/X-MultipleArgs/g' oraclexe*
sed -i 's/MimeType.*/MimeType=application\/x-database/g' oraclexe*
sed -i 's/.png//g' oraclexe*
sed -i 's/Terminal=false/Terminal=true/g' oraclexe-startdb.desktop
sed -i 's/Terminal=false/Terminal=true/g' oraclexe-stopdb.desktop
{code}
Exit root:
{code}
exit
{code}
Login as user Oracle:
{code}
su - oracle
{code}
Modify database start and stop scripts:
{code}
cd /u01/app/oracle/product/11.2.0/xe/config/scripts
cp startdb.sh start.sh_orig
cp stopdb.sh stopdb.sh_orig
sed -i 's/>.*//g' startdb.sh
sed -i 's/>.*//g' stopdb.sh
{code}
You will need SYSDBA privileges and set Oracle environment variables in order to use your regular user account.
Login to your regular user account:
{code}
su - dude
{code}
Enter the folowing command:
{code}
sudo usermod -a -G dba dude
{code}
Then update your profile to automatically set the necessary Oracle environment variables:
{code}
echo "" >>./.profile
echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >>./.profile
{code}
Update your Desktop folder to contain useful Oracle XE scripts:
{code}
cp /usr/share/applications/oraclexe* ~/Desktop
chmod 750 ~/Desktop/oraclexe*
{code}
To verify success re-login and try "sqlplus":
{code}
su - oracle
sqlplus / as sysdba
{code}
h2. 10) Tips and Troubleshooting
h3. 10. a) Port 1521 appears to be in use by another application
Error: Port 1521 appears to be in use by another application. Specify a different port.This error happens after a previously unsuccessful configuration attempt using /etc/init.d/oracle-xe configure script. The script was able to start the Listener process, but most likely failed to continue to clone the database, e.g. ORA-00845. The following should correct the problem:
Determine the oracle listener process that is already running:
{code}
$ ps -ef | grep oracle
{code}
Your output should be similar to:
{code}
oracle 19789 1 0 19:46 ? 00:00:00 /u01/app/oracle/product/11.2.0/xe/bin/tnslsnr
{code}
Then kill the process, using the appropriate process id, for instance:
{code}
$ sudo kill -9 19789
{code}
h3. 10.b) cannot touch `/var/lock/subsys/listener': No such file or directory
Starting Oracle Net Listener...touch: cannot touch `/var/lock/subsys/listener': No such file or directoryThis error occurs when you run /etc/init.d/oracle-xe configure, but failed the preinstallation step to create the /var//lock/subsys directory as outlined in chapter 8.
h3. 10.c) ORA-00845: MEMORY_TARGET
ORA-00845: MEMORY_TARGET not supported on this system See chapter 7 to enable /dev/shm and verify free space available in /run/shm
h3. 10.d) Apex ADMIN password
According to the Oracle documentation, the password for the INTERNAL and ADMIN Oracle Application Express user accounts is initially the same as the SYS and SYSTEM administrative user accounts. Well, I tried several times without success. To reset the Apex Admin password:
Login as user oracle:
{code}
su - oracle
{code}
Login as SYSDBA and type the following:
{code}
sqlplus / as sysdba
{code}
At the SQL prompt, type the following to be prompted to change the password:
{code}
SQL> @?/apex/apxxepwd.sql
exit
{code}
When done, open your browser and go to http://127.0.0.1:8080/apex
Workspace: Internal
Username: ADMIN
Password: password you set with apxxepwd.sql
I will prompt you to reset the password:
old password: password you set with apxxepwd.sql
new password: final_password
You can also login as the Apex Admin using http://127.0.0.1:8080/apex/apex_admin
h3. 10.e) SYS and SYSTEM password
Use the following commands to reset the SYS and SYSTEM passwords if necessary:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and type the following at the SQL prompt:
{code}
sqlplus / as sysdba
SQL> alter user sys identified by "password" account unlock;
SQL> alter user system identified by "password" account unlock;
SQL> exit
{code}
h3. 10.f) Uninstall Oracle 11g XE
The following will completely uninstall and remove Oracle 11g XE:
Open a terminal seesion and login as user root:
{code}
sudo su -
{code}
Enter the following:
{code}
/etc/init.d/oracle-xe stop
dpkg --purge oracle-xe
rm -r /u01/app
rm /etc/default/oracle-xe
update-rc.d -f oracle-xe remove
update-rc.d -f oracle-mount remove
update-rc.d -f oracle-shm remove
{code}
h3. 10.g) Reconfigure Oracle 11g XE
Type the following commands in a terminal window:
{code}
sudo /etc/init.d/oracle-xe stop
sudo rm /etc/default/oracle-xe
sudo /etc/init.d/oracle-xe configure
{code}
h3. 10.h) Gnome Classic desktop
Ubuntu 11 moved from the Gnome Classic desktop to Unity and removed the "Ubuntu Classic" login option. Unity was designed to make more efficient use of space given a limited screen size and touch screens. If you prefer to use the Gnome Classic desktop, enter the following into a terminal window:
{code}
sudo apt-get install gnome-panel
{code}
To log into the Gnome Classic desktop, select the "Gearwheel" at the login screen and select "Gnome Classic".
h3. 10.i) Unix vi cursor keys
The instructions in this tutorial do not require the use of any text editor. However, if you would like use the backspace and cursor keys in the "vi-editor", the following needs to be installed:
{code}
sudo apt-get install vim
{code}
h3. 10.j) Backup Database
In order to perform an online database backup using the supplied "Backup Database" script, the database needs to run in Archive-Log mode. This can be setup using the following commands:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and type the following:
{code}
sqlplus / as sysdba
SQL> shutdown immediate
SQL> startup mount
SQL> alter database archivelog;
SQL> alter database open;
SQL> exit
{code}

Dude.Excellent Blog. Thank You
Small clarification on Step **6) Oracle Home Directory, ...a) Resize the Root Partition**
Ubuntu 11.10 has Gparted available as a Ubuntu software download, DONT use that while trying the above step, instead download the ISO file from http://sourceforge.net/projects/gparted/files/gparted-live-stable/ gparted-live-0.12.0-5.iso (124.6 MB)
Burn that ISO file on a Blank DVD, reboot the Ubuntu , during startup select Boot from DVD Option if not already selected. this will take to Boot Menu Options of Gparted Live then select the first menu option, and this allows to do further action such as Re-sizing .
and once you have chosen and executed step a) . do NOT run step b) also that is "Setup External Storage"
I hope this minor clarification can avoid some confusion

Hello ,
we are currently experiencing heavy I/O problmes perfoming prrof of concept
testig for one of our customers. Our setup is as follows:
HP ProLiant DL380 with 24GB Ram and 8 15k 72GB SAS drives
An HP P400 Raid controller with 256MB cache in RAID0 mode was used.
Win 2k8r2 was installed on c (a physical Drive) and the database on E
(= two physical drives in RAID0 128k Strip Size)
With the remaining 5 drives read and write tests were performed using raid 0 with variing number of drives.
I/O performance, as measured with ATTO Disk benchmark, increased as expected linear with the number of drives used.
We expected to see this increased performance in the database, too and performed the following tests:
- with 3 different tables the full table scan (FTS) (Hint: /*+ FULL (s) NOCACHE (s) */)
- a CTAS statement.
The system was used exclusively for testing.
The used tables:
Table 1: 312 col, 12,248 MB, 11,138,561 rows, avg len 621 bytes
Table 2: 159 col, 4288 MB, 5,441,171 rows, avg len 529 bytes
Table 3: 118 col, 360MB, 820,259 rows, avg len 266 bytes
The FTS has improved as expected. With 5 physical drives in a RAID0, a performance of
420MB/s was achieved.
In the write test on the other hand we were not able to archieve any improvement.
The CTAS statement always works with about 5000 - 6000 BLOCK/s (80MB/s)
But when we tried running several CTAS statements in different sessions, the overall speed increased as expected.
Further tests showed that the write speed seems to depend also on the number of columns. 80MB/s were only
possible with Tables 2 and 3. With Table 1, however only 30MB/s were measured.
Is this maybe just an incorrectly set parameter?
What we already tried:
- change the number of db_writer_processes 4 and then to 8
- Manual configuration of PGA and SGA size
- setting DB_BLOCK_SIZE to 16k
- FILESYSTEMIO_OPTIONS set to setall
- checking that Resource Manager are really disabled
Thanks for any help.

The used tables:
Table 1: 312 col, 12,248 MB, 11,138,561 rows, avg len 621 bytes
Table 2: 159 col, 4288 MB, 5,441,171 rows, avg len 529 bytes
Table 3: 118 col, 360MB, 820,259 rows, avg len 266 bytes
The FTS has improved as expected. With 5 physical drives in a RAID0, a performance of
420MB/s was achieved.
In the write test on the other hand we were not able to archieve any improvement.
The CTAS statement always works with about 5000 - 6000 BLOCK/s (80MB/s)
But when we tried running several CTAS statements in different sessions, the overall speed increased as expected.
Further tests showed that the write speed seems to depend also on the number of columns. 80MB/s were only
possible with Tables 2 and 3. With Table 1, however only 30MB/s were measured.
If multiple CTAS can produce higher throughput on writes this tells you that it is the production of the data that is the limit, not the writing. Notice in your example that nearly 75% of the time of the CTAS as CPU, not I/O.
The thing about number of columns is that table 1 has exceeded the critical 254 limit - this means Oracle has chained all the rows internally into two pieces; this introduces lots of extra CPU-intensive operations (consistent gets, table access by rowid, heap block compress) so that the CPU time could have gone up significantly, resulting in a lower throughput that you are interpreting as a write problem.
One other thought - if you are currently doing CTAS by "create as select from {real SAP table}" there may be other side effects that you're not going to see. I would do "create test clone of real SAP table", then "create as select from clone" to try and eliminate any such anomalies.

The values came from (string to number) pattern match and were misbehaving. After tinkering with type casting and formats (didn't spend much time though), there was no change in wrong evaluation: Message Edited by labview-programmer on 06-04-2010 10:
