Step by Step installing Oracle 10g RAC on VMware

Posted by Kamran Agayev A. on April 5, 2011

In this guide I’m going to show you the process of creating Oracle 10g R2 RAC on OEL4. First of all I have to mention that I’ve prepared this guide based on the well known RAC on VMWare guide of for Vincent Chan which can be found at OTN. After using that guide I’ve decided to create a more screenshot based explained guide and prepared this blog post which contains 150 screenshots! 🙂

These days wordpress.com is working veeeeery slowly, so it took me two days to upload all images and create this blog post 🙂 That was really boring. But now the blog post is online and I would be glad to hear the visitors valuable feedbacks.

In this tutorial, we use OEL4 because Oracle 10gR2 is not compatible with OEL5 (as the db was released before the OS released) As in my all tutorials, I use vmware virtual machine. In this guide I will create two virtual machines. Let’s start creating the first machine. But before it, create three directories inside one folder (for example c:\vmware)

C:\vmware\rac1

C:\vmware\rac2

C:\vmware\sharedstorage

Create the following virtual machine in the first folder and create all shared storages in the third folder

Click Next

Select Typical and click Next

Select “Red Hat Enterprise Linux 4” and Click Next

Provide the name of the virtual machine (rac1), select the location for vmware disk (you can make it c:\vmware\rac1) and click Next

Select bridged network and click next

Define the size of the hard drive of the virtual machine and click Next (set it to 20 GB and don’t check “Allocate all disk space now” checkbox) 

Mount the ISO image of the OEL4 installation and start adding more four hard drives and one Ethernet device. Click on Add button

Select “Hard Disk” and click Next

Select “Create a new virtual disk” and click Next

Select “SCSI” and check “Independent->Persistent” and click Next

For the first device, specify the disk size as “3gb”, check “Allocate all disk space now” and click Next

Create a separate folder named “C:\vmware\sharedstorage” in your hard drive, set the name of the new hard drive to “ocfs2disk.vmdk”.

After creating the first device, create more three devices with 4GB in size (asmdisk1.vmdk, asmdisk2.vmdk, asmdisk3.vmdk) and make all of them “Independent->Persistent” and don’t allocate the disk space for each of them

Next, start changing the device node for each of them. Start from the firstly added hard drive, select it, click on Advanced button and make it SCSI 1:0. For next hard drive make it 1:1 and so on

Add new Ethernet device

Change the network connection to “Host-only”

Make sure that the last state of your virtual machine looks like as it’s seen above

Then locate the configuration file of the virtual machine and start editing it

Add the lines that are marked in bold to the configuration file to make the devices be shared between to nodes

–          By specifying “disk.locking” to FALSE will allow any virtual machine to load a SCSI disk device even it’s in use by an another virtual machine

–          Specify “diskLib.dataCacheMaxSize = “0” to turn off the disk caching for clustered virtual machines.

–          By specifying scsi1.sharedBus = “virtual” will give the whole bus the ability to be shared. This prevents the locking of this specific disk

Start the virtual machine

As you have already mounted the ISO image of the OEL4, the above screen appears

Click Skip

Click Next

Select installation language and click next

Select appropriate keyboard and click next

Select “Server” as the installation type and click Next

Select Disk Druid for disk partitioning method and click Next

Click Yes for all warnings and click Next

Double click in the first drive /dev/sda

Specify ‘/’ as a mount point, make its files system “ext3” and make the End Cylinder 900 (to make the size of the root folder 7Gb). Check “Force to be a primary partition” and click Ok

Select File System Type as “swap” and change End Cylinder to 1170

Create mount point called /u01, make its files system “ext3” and make End Cylinder 2610 and click Ok

Make sure that the last state of your disk partitioning looks like as it’s seen above

Now let’s configure the network devices. Select the first device and click Edit

Uncheck “Configure using DHCP” and provide the following ip address and netmask:

IP Address: 192.168.2.131

Netmask: 255.255.255.0

Select the second device, edit it, uncheck “Configure using DHCP” and provide the following ip address and netmask

IP address: 10.10.10.31

Netmask: 255.255.255.0

Set the hostname as “rac1.test.az” (you can provide any domain name) and set the gateway to 192.168.2.1

Disable Firewall and SELinux and click Next

Select the default language for the system and click Next

Select Time-Zone and Click Next

Provide the password for the root user and click next

Select necessary packages for Oracle installation. Here’s the list of the necessary packages:

X Window System

Gnome Desktop Environment

Editors

Graphical Internet

Server Configuration Tools

Legacy Network (click Details and select “rsh_server” and “telnet-server”)

Development Tools

Legacy Software Development

Administration Tools

System Tools (select all packages that starts with “ocfs2” and “oracleasm”, select “systat” as well)

Click Next to start the installation

After installation completed the machine restarts. Click Next

Agree with license and click Next

Set the date and time and click Next

Set the display and click Next

You don’t need to create a user so click Next

Click Next

Click Next and finish the installation

Now let’s install vmware tools. For this, disconnect the mounted ISO image, choose “Install VMware Tools” from VM menu

Double click on VMware tools icon and run the .rpm file by double clicking on it

After the window is closed, open new terminal and run vmware-config-tools.pl  and finish the installation of vmware tools

 

To synchronize the time on the virtual machine with the host machine execute “vmware-toolbox” on the terminal window and check the check box

Edit /boot/grub/grub.conf file and add “clock=pit nosmp noapic nolapic” to the line that reads kernel /boot

The “clock=pit” prevents the clock for running to quickly and “nosmp noapic nolapic” prevents the clock from running too slowly. After you make the change, reboot the machine for change to take effect

Now let’s start the prerequisite steps for Oracle installation. For this we’ll create a group, a user and some directories

groupadd oinstall

groupadd dba

mkdir -p /export/home/oracle

mkdir /ocfs

useradd -d /export/home/oracle -g oinstall -G dba oracle

chown oracle:dba /export/home/oracle /u01

passwd oracle

Change the .bash_profile (and .bashrc) file and add the following lines:

export EDITOR=vi

export ORACLE_SID=devdb1

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1

export LD_LIBRARY_PATH=$ORACLE_HOME/lib

export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin

umask 022

Now switch to oracle user with “su – oracle” command. Make sure all environment variables are set (echo $ORACLE_HOME).  After that, create the following directories:

su - oracle

mkdir -p $ORACLE_BASE/admin

mkdir -p $ORACLE_HOME

mkdir -p $ORA_CRS_HOME

mkdir -p /u01/oradata/devdb

Note that if environment variables are not set correctly, then the above mentioned directories will not be created.

Change /etc/security/limits.conf file with a root user and add following lines:

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

Change /etc/pam.d/login file and add the following line:

session required /lib/security/pam_limits.so

Now mount the third installation cd of the OEL4, connect it and open new terminal. Switch to the RPMS folder inside the cd and install “libaio-0.3.105-2.i386.rpm” and “openmotif21-2.1.30-11.RHEL4.6.i386.rpm” packages

rpm –Uvh libaio-0.3.105-2.i386.rpm

rpm –Uvh openmotif21-2.1.30-11.RHEL4.6.i386.rpm

Change /etc/sysctl.conf file and add the following lines:

kernel.shmall                = 2097152

kernel.shmmax                = 2147483648

kernel.shmmni                = 4096

kernel.sem                   = 250 32000 100 128

fs.file-max                  = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default        = 1048576

net.core.rmem_max            = 1048576

net.core.wmem_default        = 262144

net.core.wmem_max            = 262144

Then execute the following command for change to take effect:

/sbin/sysctl -p

Now let’s configure the network configuration files. For this we need to add IP addresses and hostnames to the /etc/hosts file in each node and test the connection by pinging the hostnames

127.0.0.1               localhost

192.168.2.131           rac1.test.az        rac1

192.168.2.31            rac1-vip.test.az    rac1-vip

10.10.10.31             rac1-priv.test.az   rac1-priv

192.168.2.132           rac2.test.az        rac2

192.168.2.32            rac2-vip.test.az    rac2-vip

10.10.10.32             rac2-priv.test.az   rac2-priv

Try the connection by pinging all hostnames (don’t ping VIP addresses as they will be created during clusterware installation):

ping rac1.test.az

ping rac1-priv.test.az

and son on

Now start creating disk partitions for OCFS2 and ASM. /dev/sdb will be used for OCFS2 and rest devices will be used for ASM.

fdisk /dev/sdb

Type n (to create new partition)

Type p to create a primary partition

Type 1 to provide the partition number

Double click on Enter and type “w” to save the changes

Perform above steps for all hard disk:

fdisk /dev/sdc

fdisk /dev/sdd

fdisk /dev/sde

To map the raw devices to the shared partitions, change /etc/sysconfig/rawdevices file:

/dev/raw/raw1 /dev/sdc1

/dev/raw/raw2 /dev/sdd1

/dev/raw/raw3 /dev/sde1

And run the following command to make it effective

/sbin/service rawdevices restart

Then change the permission for all newly created raw devices:

chown oracle:dba /dev/raw/raw[1-3]

chmod 660 /dev/raw/raw[1-3]

ls -lat /dev/raw/raw*

Next, switch to the oracle user and create links for raw devices

su - oracle

ln -sf /dev/raw/raw1 /u01/oradata/devdb/asmdisk1

ln -sf /dev/raw/raw2 /u01/oradata/devdb/asmdisk2

ln -sf /dev/raw/raw3 /u01/oradata/devdb/asmdisk3

As the raw devices are remapped on boot, change /etc/udev/permissions.d/50-udev.permissions with the root user and add the following lines:

# raw devices

ram*:root:disk:0660

#raw/*:root:disk:0660

raw/*:oracle:dba:0660

After performing all above steps, shutdown the virtual machine. Then copy all its files to another directory (c:\vmware\rac2)

Open it, switch to the Options tab, change its name to “rac2” and start it

Open Network Configuration and change addresses of each Ethernet device.

eth0 – 192.168.2.132

eth1 – 10.10.10.32

Then from Hardware Device type click on “Probe” button to get new MAC address, enable both network devices, change hostname to rac2.test.az and click Ctrl+S to save the changes. Then add the following line to the /etc/hosts file

127.0.0.1              localhost

Now it’s time to establish user equivalence with SSH. Oracle Universal Installer installs the binaries in one node and then propagates the files to the other nodes. For this, it uses ssh and scp command in the background during installation to run remote commands and copy files to the other cluster nodes. So SSH must be configured so that these commands not prompt for a password. For this power on the first machine, login with root user, switch to the oracle user and generate RSA and DSA key pairs

su – oracle

ssh-keygen –t rsa (click Enter twice)

ssh-keygen –t dsa (click Enter twice)

Perform above steps in the second node (rac2)

Now (from rac1) add the generated keys to the ~/.ssh/authorized_keys file

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

Then from rac1 SSH to rac2 twice and add the .rsa and .dsa keys to the “authorized_keys” file that locates in the first node:

ssh rac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

ssh rac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

Now copy the “authorized_keys” file from rac1 to rac2:

scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys

After performing all above steps, you should successfully open SSH connection from rac1 to rac2 and vice verse. So run the following commands in both nodes and ensure that you’re not prompted for the password for the second time:

ssh rac1 date

ssh rac2 date

ssh rac1-priv date

ssh rac2-priv date

ssh rac1.test.az date

ssh rac2.test.az date

ssh rac1-priv.test.az date

ssh rac2-priv.test.az date

I want to note again “Please make sure that after running above commands on each node, you’re not prompted for the password for the second time”

Now let’s configure Oracle ASM (Automatic Storage Management). So run the following commands from both nodes with root user:

/etc/init.d/oracleasm configure

Pass “oracle” as a parameter for “default user”

Pass “dba” as a parameter for “default group”

Pass “y” for the third and fourth parameters

Then create ASM disks on any node (try on the first node – rac1) with a root user:

/etc/init.d/oracleasm createdisk VOL1 /dev/sdc1

Marking disk “/dev/sdc1” as an ASM disk:                   [  OK  ]

/etc/init.d/oracleasm createdisk VOL2 /dev/sdd1

Marking disk “/dev/sdd1” as an ASM disk:                   [  OK  ]

/etc/init.d/oracleasm createdisk VOL3 /dev/sde1

Marking disk “/dev/sde1” as an ASM disk:                   [  OK  ]

Verify that the ASM disks are visible from every node.

/etc/init.d/oracleasm scandisks

Scanning system for ASM disks:                      [  OK  ]

/etc/init.d/oracleasm listdisks

VOL1

VOL2

VOL3

Now let’s configure Oracle Cluster File System (OCFS2). For this, run “ocfs2console” with a root user from the first node. Then from the Cluster menu select Configure Nodes, click Add button and apply both nodes:

rac1

192.168.2.131

7777

rac2

192.168.2.132

7777

Then propagate the configuration to the second node. For this select “Propagate Configuration” from the Cluster menu.

To configure O2CB to start at the boot unload and configure it on both nodes as a root user:

/etc/init.d/o2cb unload

/etc/init.d/o2cb configure

and pass the following parameters

“y”

ocfs2

61

Now format the file system on the first node (rac1). For this run ocfs2console program, select Format from the Tasks menu and click OK to format the drive. Press Ctrl+Q to quit

Now execute the following command on both nodes to mount the files system

mount -t ocfs2 -o datavolume,nointr /dev/sdb1 /ocfs

and add the following line to the /etc/fstab to mount the files system on boot

/dev/sdb1 /ocfs ocfs2 _netdev,datavolume,nointr 0 0

Create a “clusterware” directory under /ocfs folder and change the owner:

mkdir /ocfs/clusterware

chown -R oracle:dba /ocfs

Now to test the shared device, create a file in the /ocfs directory from the first node (rac1) and check the same folder in the second node.

cd /ocfs

touch test_file

ls

Now download the clusterware installation, copy it under /tmp directory, unzip it and start the installation

./runInstaller

Provide the folder for the Inventory and click Next

Create a “clusterware” directory under /ocfs folder and change the owner:

mkdir /ocfs/clusterware</span></p>
<p class="MsoNormal" style="margin: 0 0 10pt;"><span style="font-family: Calibri; font-size: small;">chown -R oracle:dba /ocfs

 

 

 

Now to test the shared device, create a file in the /ocfs directory from the first node (rac1) and check the same folder in the second node.

cd /ocfs

touch test_file

ls

Now download the clusterware installation, copy it under /tmp directory, unzip it and start the installation

./runInstaller

 

Provide the folder for the Inventory and click Next

Change the CRS folder to /u01/app/oracle/product/10.2.0/crs_1 and click Next

After checking all prerequisites it should not give any warning, so click Next

Click on Add button and provide the information on the second node:

Public Node Name: rac2.test.az

Private Node Name: rac2-priv.test.az

Virtual Host Name : rac2-vip.test.az

Click on Edit button, change the Interface type of the first Ethernet device (eth0) to “Public” and the second to “Private”

Select External Redundancy and provide the location for OCR :

/ocfs/clusterware/ocr

 

Select External Redundancy and provide the location for Voting Disk

/ocfs/clusterware/votingdisk

Now click Install button to start the clusterware installation

After installation completes, run both scripts on both nodes

Run /u01/app/oracle/oraInventory/orainstRoot.sh on rac1 and rac2 (wait each script to complete before running it on the second node)

Run /u01/app/oracle/product/10.2.0/crs_1/root.sh on rac1 and rac2 (wait each script to complete before running it on the second node)

After running the second script on the second node (rac2) you’ll get an error (on running VIPCA), so you need to run it manually. Switch to the following directory

cd /u01/app/oracle/product/10.2.0/crs_1/bin

and run the ./vipca to create and configure VIP

Select the first Ethernet device and Click Next

After running the second script on the second node (rac2) you’ll get an error (on running VIPCA), so you need to run it manually. Switch to the following directory

cd /u01/app/oracle/product/10.2.0/crs_1/bin

and run the ./vipca to create and configure VIP

Select the first Ethernet device and Click Next

 

Type “rac1-vip” on the IP Alias Name for the first node (rac1). The rest boxes will be filled automatically. Click Next

Click Finish to start the installation

After vipca finished successfully, switch to the first node and click OK button on the “script running” window.

Click Exit button to exit the installation of an Oracle Clusterware

Now copy the installation of the database (Oracle 10gR2) to the /tmp directory, unzip and start the installation. You need to start the installation with an oracle user, so run “xhost +” from the root user to allow the connection to the X server and switch to the oracle user

xhost +

su – oracle

./runInstaller

Select “Enterprise Edition” and click Next

Provide the installation directory (/u01/app/oracle/product/10.2.0/db_1)

Select both nodes and click Next

The prerequisite check should be successful, so click Next

Let’s install just a software, so check “Install database Software only” and click Next

Click Install to start the installation

Execute the mentioned script on both nodes (wait for the script to finish before running it on the second node)

After installation finishes, run “dbca” (Database Configuration Assistant), select “Oracle Real Application Clusters database” and click Next

Select “Configure Automatic Storage Management” and click Next

Select both nodes and click Next

Provide the password for an ASM instance, select “Create initialization parameter file (IFILE)” and click Next

Click OK to create and ASM instance on both nodes

Click YES to create listener on both nodes

Now let’s create an ASM disks. For this, click “Create New” button

Provide the name of the diskgroup “dg1”, select the “External” redundancy, select two disks “raw1,raw2” and click OK

The disk group will not be mounted in the second node, so omit this warning. The second node should be restarted (but not now)

Create the second disk group for flash recovery area (fg), select an “External” redundancy, select the last device (raw3) and click Ok

As you see, the state of disk group shows that it’s not mounted on the second node. For this, we need to restart the second node. Click on Finish and restart the second node. After it starts, login with root user and call dbca from the first node again.

Move to the above window again and you’ll see that the disk group is mounted on both nodes. Click on Finish button

Run dbca again and select “Create a Database”

Select both nodes and click Next

Select “General Purpose” and click Next

Provide the database name “devdb” and click Next

Uncheck “Configure the Database with Enterprise Manager” as it’s taking too much (some hours) to finish (however, if you have enough RAM, you can check it) and click Next

Provide the password for the SYS user and click Next

Select “Automatic Storage Management” and click Next

Provide the password for ASM and click OK

Select the first disk group and click Next

Select “Use Oracle-Managed Files” and click Next

Check “Specify Flash Recovery Area” and chose “FG” disk group and click Next

Click Next

Click Next (We’ll create TAF afterwards)

Click Next

Click Next

Click Finish to start the installation

After some hours (as I was running each virtual machine with 1GB RAM) this screen appears. Click Exit

Now both instances will be started.

After all, check the status of the Clusterware. As you see, some applications are with “OFFLINE” state. To make them online, stop and start them with SRVCTL utility as it’s shown above

After all, check the CRS status again. As you see, the State column of all applications are ONLINE

Now connect to the database from the first node (rac1) and run the following query

SQL>col host_name format a20

SQL>SELECT instance_name, host_name, thread#, status from gv$instance;

Try the conection to both instances:


[oracle@rac1 ~]$ sqlplus system@devdb1

Now let’s create a Service. Services are used to manage the workload in an RAC environment and provide high availability.  To create the service run “dbca”

Select the first option and click Next

Select “Service Management” and click Next

Select the first database and click Next

Provide the name of the Service and click Next

When you specify PREFERRED instances, you are specifying the number of instances on which a service will normally run. The Oracle Clusterware attempts to ensure that the service always runs on the number of nodes for which you have configured the service. Afterwards, due to either instance failure or planned service relocations, a service may be running on an AVAILABLE instance

Select Preferred for the first instance, and Available for the second instance, change the TAF policy to Basic and click Finish

After the Service created automatically, check tnsnames.ora file and you’ll see that the new entry is added

When you specify PREFERRED instances, you are specifying the number of instances on which a service will normally run. The Oracle Clusterware attempts to ensure that the service always runs on the number of nodes for which you have configured the service. Afterwards, due to either instance failure or planned service relocations, a service may be running on an AVAILABLE instance

Select Preferred for the first instance, and Available for the second instance, change the TAF policy to Basic and click Finish

After the Service created automatically, check tnsnames.ora file and you’ll see that the new entry is added

Try to connect to the database using this service. As you see, we’ll automatically connect to the first instance. Now let’s check the RAC high availability

For this, while connecting to the first instance (devdb1) using a “service”, open new terminal, connect to the first instance and shut it down

Now go back to the first session and query the v$instance view again. As you see, you’ll be automatically forwarded to the second instance

In this step by step tutorial I’ve shown you the deep step by step guide using 150 screenshots to make the RAC installation easier for you. I hope you’ll successfully install RAC and make your own tests. Good Luck!

    Dear Mr. Kamran,

    Thanks alot for sharing such a nice tutorial. I have been waiting for RAC for so long.

    Can we use the same method with 11g versions. Please let me know.

  16. Dear Amis, thanks for feedback

    No, in 11g it’s different, I’ll try to put an article on 11g as well 🙂

  17. […] In this guide I’m going to show you the process of creating Oracle 10g R2 RAC on OEL4. First of all I have to mention that I've prepared this guide based on the well known RAC on VMWare guide of for Vincent Chan which can be found at OTN. After using that guide I've decided to create a more screenshot based explained guide and prepared this blog post which contains 150 screenshots! These days wordpress.com is working veeeeery slowly, so it too … Read More […]

  21. Dear ISS

    Have you done all steps as it’s shown in the screenshots? The first ethernet device should be “Bridged” and the second should be “Host only”

    moreover, you need to start them both

    i’m using vmwareworkstaton 7 in windows 7, but after creating rac1 vmmachine, wen i tried to install RedHat linux 4 version..the slides are not same sa here ..meaning DHCP seetings (network settings).I’m afraid to move ahead. i don’t have Oracle Enterprise Linux..am using RedHat Linux 4.
    Appreciate you could say is it okay to move.

  30. Jerry said

    All good until I get to the ASM and OCFS2 setup section.

    Neither oracleasm nor ocfs2console exist in the OEL4 VM. Is there an installation section missing or have I missed a step?

  31. Dear Jerry

    You have to install it during OS installation

  32. Dear Lalitha, please download OEL 4 and perform your test on that OS

    Dear Kamran,
    How I can check that my OLE 4.8 vmware is sharing disks.

    I check /etc/ocfs2/cluster.conf that is properly formatted and when I check status of o2cb it shows me Active heartbeat at node1 only.

    Hi,
    Sir u have clearly mentioned u are using OLE4 but sir i don’t have ant\y other version as if i change the /etc/redhat-release 5.5 to 4 will that work as in cse of installation of oracle

    Regards
    Deepika

  48. Dear Deepika

    There may be some differences in configuration file of the vmware due to the version difference. And the installation RAC on OEL 5 has some pre-requisites (as it is not certified), so would suggest you to get the correct vmware and OEL (you can download OEL 4 from this link – http://edelivery.oracle.com/linux)

  49. Great documentation on how to set up Oracle on VMware! A great tool to view all of the layers of virtual environment to see how your databases are performing in VM is IgniteVM. You can download a free trial of IgniteVM at http://www.confio.com. IgniteVM will show your Tops Sqls/Waits along with Database Health Metrics, the VM/OS guest layer, Host layer and Storage layer in one screen to help you quickly identify bottlenecks at any of the layers.

    Hi Kamran
    First of all, congratulations for the great article. Very good information. But I have a question. Hope you can help on that.

    I have followed all the steps, and I’m able to mount the ocfs share in both nodes, but I’m not able to see files that a create in such nodes. I mean, the file that I create from rac1, can’t be seen in rac2. Please, let me know if you have any idea about what is the problem that I’m facing.

    I used the following command to mount
    mount -t ocfs2 -o datavolume,nointr /dev/sdb1 /ocfs

    and also added instructions in /etc/fstab

    but when testing
    cd /ocfs
    touch test_file

    I can’t see file in node 2. If I created from node 2, I can’t see in node 1.

    Thanks,
    Vantuir

  73. Vantuir Teixeira said

    Kamran,
    I have dropped and node 2 and recreated everything from the scratch. After that, I configured OCFS share again, and it could be seen by both nodes correctly.
    Thanks for the article. Very good one.

    My only suggestion is to add some lessons learned and common problems that you faced in a new session.

    Thanks,
    Vantuir

    Host Configuration : INTEL Dual Core 1.80 Ghz Processor & 3 GB RAM

    Both Guest Machines boot up fine. But as I open one DB instance then execution & I/O performance is slow.
    But performance is extremely poor after opening 2nd DB instance.
    CPU usage by oracle on Guest Machine is around 10-30 %.

    Guest Machines do not swap & RAM usage on each guest is not more than 700MB. RAM usage decreases with time.

    But after all I am unable to understand WHY performance is so bad.

    As I think Resource Usage by VMWARE is not more than 50% but after that its performing very slow.
    Can you share your views to Diagnose & Resolve the performance problem ???

    Thanks,
    Naveen Sheokand

    Hi Kamran,

    Thank you for posting this nice blog, while configuring hardware , regarding the ethernet adapters, while I’m chosing the option to specify ethernet adapters details, Can I make use of the existing network adapters within the laptop or should I be using a new ethernet adapter installing it into laptop first and then my VM will be able to chose from it? . At present when I try to add the network adpaters section, I’ve only one option i.e Physical network and nothing related to ethernet adapters…please specify some details about this.

    Thanks
    Rajiv.
