Oracle provides the Smart Update utility to apply patches and upgrade the WebLogic Server installations. Oracle’s Weblogic Server is now a critical component of Fusion Middleware and every other component of Fusion Middleware requires Weblogic Server to be installed as a pre-requisite. Applying patches and upgrading Weblogic Server is quite straight forward using the Oracle’s Smart Update utility,the documentation for Oracle Smart Update Utility can be found here
1. Shutdown and take a complete backup of the WLS environment.
The Startup/Shutdown scripts are placed in $WLS_HOME/user_projects/domains/<domain_name>/bin
2. The Oracle Smart Update Tool is located at “$WLS_HOME/utils/bsu”
3. Launch the the Oracle Smart Update Tool :
4. Once logged in, you will be presented with Oracle Smart Update Dialog.
5. You can choose to “Register for security updates”, this is usually helpful to keep yourself updated with the latest security updates and product expiration.
7. On the left pane you would see Weblogic Servers installed and on the right pane you will see two tabs. “Get Patches” and “Manage Patches” and a section to show the downloaded patches.
8. Now select the patches and hit the “Download Selected” button, you will be prompted if you wish to to validate and resolve conflicts.
9. The Validation completes with the following message:
11. Once the patches are downloaded and click the “Manage Patches” tab to proceed with the patch application. In the “Downloaded Patches” section you will notice the patches downloaded, click the “up” arrow to apply the patch
12. You will be prompted with couple of prompts for you to take action:
13. Once more the validation is done, click “OK” to proceed
14. One more “Are you sure?” prompt, annoying I know :). Click “Proceed” to apply the patch
Thats it the patch is now applied. If you face any issues its worth investigating the server logs.

This post talks about the Conversion of 11gR2 non-RAC database to RAC database using rconfig.
Oracle provides 3 methods to convert non-RAC single instance database to RAC databases:
3. Enterprise Manager
All the 3 have their own benefits and can be used to suit one’s needs. My recent work involved the conversion of non-RAC single instance database to RAC database using rconfig, although I’ve tested all the 3 methods but concluded on rconfig.
1. Configure Shared Storage setup ASM, NFS (NAS) or clustered storage.
- For ASM, refer to Oracle Database Storage Administrator’s Guide11g Release 2 (11.2)
- For configuring shared storage, refer to Configuring Storage for Grid Infrastructure for a Cluster and Oracle Real Application Clusters (Oracle RAC) (Linux)
- See also Oracle Database Administrator’s Guide 11g Release 2 (11.2)
2. A clustered Grid Infrastructure install with at least one Scan listener address. See
3. rconfig imposes a restriction on the choice of listener. The listener must be the default listener, and it must run from the Grid Infrastructure home.
srvctl add listener -p 1522
After conversion, you can reconfigure the listener as required.
4. Install Clustered Oracle Database Software as per documentation, this can be done by choosing the right configuration option. Refer to :
I’ve installed the new 11gR2 clustered ORACLE_HOME at
on both the nodes orarac01 and orarac02
Converting Single Instance Database using rconfig
1. As an “oracle” OS user navigate to
2. Open the sample file ConvertToRAC_AdminManaged.xml using a text editor such as vi. This XML sample file contains comment lines that provide instructions on how to edit the file to suit your site’s specific needs.
3. Ensure you edit the xml with
convert verify="ONLY"The following are the sample entries:
<!--Specify current OracleHome of non-rac database for SourceDBHome --> /u01/app/oracle/product/11.2.0/db_1 <!--Specify OracleHome where the rac database should be configured. It can be same as SourceDBHome --> /u01/app/oracle/product/11.2.0/db_2 <!--Specify SID of non-rac database and credential. User with sysdba role is required to perform conversion --> ... <!--Specify the list of nodes that should have rac instances running for the Admin Managed Cluster Database. LocalNode should be the first node in this nodelist. --> ... <!--Specify Database Area Location to be configured for rac database.If this field is left empty, current storage will be use d for rac database. For CFS, this field will have directory path. --> +DATA
4. Move the spfile to the shared location, in this case the Single Instance Database was hosted on file system, in this process we will move the datafiles from file system storage to ASM.
So create spfile in the shared disk location
SQL>create spfile='+DATA/TEST/spfiletest.ora' from pfile;
You can check if the file is created through “asmcmd”
5. Take a backup of existing $SOURCE_ORACLE_HOME/dbs/initTEST.ora, and create a new $SOURCE_ORACLE_HOME/dbs/initTEST.ora with the following parameter:
6. Restart the Database
7. Now lets test if “rconfig” is ready for conversion, navigate to $ORACLE_HOME/bin and issue the following command
The above command validates( as we’ve set convert=”ONLY”) if rconfig is ready for conversion. If the output throws any error, diagnose and troubleshoot to fix the issue. Refer to the following output for successful validation:
... Operation Succeeded There is no return value for this step ..
8. Now are we are ready for conversion, edit the xml file “ConvertToRAC_AdminManaged.xml” and change:
.. <n:Convert verify="ONLY"> ..
.. <n:Convert verify="YES"> ..
9. Perform the conversion
The conversion will take some time to complete. The progress can be monitored from the logs located at $ORACLE_BASE/cfgtoollogs/rconfig
10. Once the conversion is complete you’d get a similar message in step 7.
11. Perform sanity checks and tweak the listener to suit your needs.
That sums up the procedure to convert Single Instance Oracle Database to RAC database. Please do share your thoughts and comments.

My Second blog…. 🙂
Thist post is about installation of Oracle 10g R2 on Solaris 10. If you wish to install Solaris 10 on VMware heres the link.
Having installed Oracle 10g and various other releases as a part of project implementations/upgrade on various environments thought it’d be a good idea to spread the knowledge :).
I have installed Oracle 10g R2 on the Solaris 10 VM I created last week(see my earliar post).
So.. Lets get started..
Database: Oracle Database 10g R2
1. Determine the physical RAM size:
# /usr/sbin/prtconf | grep "Memory size" Memory size: 1024 Megabytes #
2. To determine the size of the configured swap space, enter the following command:
# /usr/sbin/swap -s total: 360448k bytes allocated + 72480k reserved = 432928k used, 1335996k available #
3. Ensure /tmp has atleast 400MB, you can set different “temp” location by setting the environment variables “TMP” and “TMPDIR”
# df -k /tmp
4. Ensure there is enough disk space to install Oracle Software and Create starter database:
# df -h /ora10g Filesystem size used avail capacity Mounted on /dev/dsk/c1t1d0s6 7.9G 8.0M 7.8G 1% /ora10g #
5. Determine the System Architecture
# isainfo -kv 64-bit amd64 kernel modules #
6. Check Software Requirements
# pkginfo -i SUNWarc SUNWbtool SUNWhea SUNWlibm SUNWlibms SUNWsprot \ SUNWtoo SUNWi1of SUNWi1cs SUNWi15cs SUNWxwfnt system SUNWarc Lint Libraries (usr) system SUNWbtool CCS tools bundled with SunOS system SUNWhea SunOS Header Files system SUNWi15cs X11 ISO8859-15 Codeset Support system SUNWi1cs X11 ISO8859-1 Codeset Support system SUNWi1of ISO-8859-1 (Latin-1) Optional Fonts system SUNWlibm Math & Microtasking Library Headers & Lint Files (Usr) system SUNWlibms Math & Microtasking Libraries (Usr) system SUNWsprot Solaris Bundled tools system SUNWtoo Programming Tools system SUNWxwfnt X Window System platform required fonts #
If you do not find any patches installed, use the following command to add the packages:
#pkgadd -d /cdrom/sol_10_1106_x86/Solaris_10/Product <Package Name>
7. Hostname / Domain Name Checks:
If you use DNS:
#cat /etc/nsswitch.conf | grep hosts
In this case I did not use DNS, so I’d do the following:
# hostname orasun02 # domainname XYZ.com # cat /etc/hosts | grep `eval hostname` 192.168.1.106 orasun02.XYZ.com orasun02 loghost #
8. Creating Oracle User and Groups
- Create Oracle Inventory Group(oinstall)
# /usr/sbin/groupadd oinstall
- Create OSDBA group (dba)
# /usr/sbin/groupadd dba
- Create Project Group
# projadd group.dba # projects -l group.dba group.dba projid : 101 comment: "" users : (none) groups : (none) attribs: #
- Add resources to project “group.dba”
#projmod -sK "project.max-shm-memory=(privileged,2G,deny)" group.dba #projmod -sK "project.max-sem-ids=(privileged,100,deny)" group.dba #projmod -sK "project.max-shm-ids=(privileged,100,deny)" group.dba #projmod -sK "project.max-sem-nsems=(privileged,256,deny)" group.dba
- Create “oracle” user
#useradd -g oinstall -G dba -m -d /export/home/oracle -s /bin/ksh -K project=group.dba oracle
- Set the password of the oracle user:
# passwd -r files oracle
- Verify user “nobody” exists:
# id nobody uid=60001(nobody) gid=60001(nobody) #
9. Creating Directories
#mkdir -p /ora10g/oracle/ #chown -Rh oracle:oinstall /ora10g/oracle #chmod -R 755 /ora10g/oracle
10. Login to user “oracle” and edit “.profile” to set ORACLE_BASE,ORACLE_HOME,etc
# Oracle Settings TMP=/tmp; export TMP TMPDIR=$TMP; export TMPDIR ORACLE_BASE=/ora10g/oracle; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME ORACLE_SID=ORCL; export ORACLE_SID PATH=$ORACLE_HOME/bin:$PATH; export PATH
- Allow user “oracle” to use the display(Here I assume you’d be using Xterm like Xorg/XSun/vncserver/etc, so login as “root” and issue the following command:
Ensure the display is working for user “oracle”
# su - oracle $DISPLAY=orasun02:0.0 $export DISPLAY $/usr/bin/xclock $
- Unpack the Oracle 10g Software:
#unzip -o 10201_database_solx86_64.zip
- Invoke “runInstaller”
- Select Installation Method, I have chosen “Advanced Installation” and click “Next”
- Select Installation Type, I have chosen “Enterprise Edition”, Click “Next” to proceed further
- Specify Oracle Home details, this is already picked up as we specified in .profile, confirm if its right , alternatively change as desired. Click “Next” to continue
- Now Oracle does Product Specific Pre-requisite Checks, if you see it failed with 2 warnings and if you notice we have not set the kernel parameters shown in the sceenshot. This is fine as in Solaris 10 the resources are managed through the resource control, as we have configured in step 8.
- Select Configuration Option, Choose radio button “Create Database” and click “Next”
- Select Database Configuration , choose “General Purpose Database” and click “Next”
- Specify Database Configuration Options, the screen look similar to as below screenshot, and click “Next”
- Select Database Management Option, click “Next”
- Specify database storage option, should like the screenshot below, click “Next” to continue
- I have chosen not to enable automated backups, Click “Next”
- Specify Database Schema Passwords and click “Next”
- Finally.. click “Install” to start the installation.
- After the installation finishes and starter database is created, Execute the configuration scripts, show in the below screenshot
From the terminal execute the “root.sh” as user “root”:
# /ora10g/oracle/product/10.2.0/db_1/root.sh Running Oracle10 root.sh script... The following environment variables are set as: ORACLE_OWNER= oracle ORACLE_HOME= /ora10g/oracle/product/10.2.0/db_1 Enter the full pathname of the local bin directory: [/usr/local/bin]: Copying dbhome to /usr/local/bin ... Copying oraenv to /usr/local/bin ... Copying coraenv to /usr/local/bin ... Entries will be added to the /var/opt/oracle/oratab file as needed by Database Configuration Assistant when a database is created Finished running generic part of root.sh script. Now product-specific root actions will be performed. #
Then go back to Oracle Universal Installer screen and click “OK”
- Thats it , its the end of installation and your database should be up and running.
- Lets login to the Oracle Enterprise Manager 10g

During the weekend I was looking into installing Solaris 10 on VMware,
I tried to document the step by step procedure while accomplishing this task.
So…Lets get started…
- Host OS: CentOS 5- 64 bit
- Guest OS: Solaris 10 – 11/06
- VMware Version: VMware Server 1.0.4 Build 56528
Once you have VMware server installed, invoke VMware server and do the following:
- Create New Virtual Machine by selecting File -> New -> Virtual Machine.
- Click “Next”, Virtual Machine Configuration -> Custom
- Guest Operating System “Solaris 10 64-bit”
- Name the Virtual Machine whatever you feel like, I named it “orasun01” and click “Next”
- “Number of processors ” choose “One” and click “Next”
- Access Rights, Uncheck “Make this Virtual Machine Private” and click “Next”
- Allocate Memory to the VM, I have given 1024M. Click “Next”
- Network Connection , choose “Bridged Networking” and click “Next”.
- Create New Virtual Disk and click “Next”
- Virtual Disk Type, select “SCSI” and click “Next
- Specify Disk Capacity, Choose 10.0 GB and uncheck “Allocate Disk Space Now” and Click “Next”.
- Specify Disk File Name, name it differently if you wish or leave it as it is and click “Finish”.
So your VM should look like this:
Source Solaris 10 ISO during boot up
Source Solaris 10 ISO image to be read on boot up, this can be done by clicking:
Edit Virtual Machine -> select “CDROM” -> Click radio button “use ISO image” -> give the location of the Solaris 10 downloaded ISO image. Then click “OK”
From the above we have configured the VM to install Solaris 10. Lets start installing Solaris 10…
Installation of Solaris 10
- “Power On” the Virtual Machine and you should see the “Grub Menu” Select “Solaris” from the menu and press enter/return key.
- Choose “Solaris Interactive (default)” from the menu and press enter/return key.
- Select Language , I have chosen “English”
- Click “Next”
- Select the radio button “Networked” and click “Next”
- This section lets you enable DHCP, I have chosen not to select DHCP. I feel it is best to assign ip manually , gives you more control ..:)
- Enter the hostname and click “Next”
- Enter Ip address, ensure this ip is free and not used by any other system.
- Enter “NetMask”, I have selected it default value which was automatically picked up.
- Select “Yes” if you like to enable IPv6,
- Select “Default Route”, I have selected “none” as this can be defined at later point in time.
- Select “No” if you do not intend to use Kerberos Security.
- Select your desired “Name Service”, I have selected “None”
- Select “Time Zone”, I chose the radio button “Geographic Continent/Country/Region”
- Select your relevant country
- Confirm “Date and Time” and click “Next”
- Enter “root” password and click “Next”
- Select “Yes” if you wish to Enable Remote Services and click “Next”
- Confirm the “Summary” and proceed to next section by clicking “Confirm“
- Click “Next” to go to the next tasks of Installation
- In the “Installer Options” click the radio button “No” for Reboot automatically after installation and “No” for “Eject CD/DVD after Software Installation” and click “Next”
- A Notice will pop up to you should also eject the CD/DVD. Click “OK” to continue.
- Specify Media, click radio button “CD/DVD” and click “Next” to continue
- Accept the “License” and click “Next”
- Select “Type of Install”, choose “Custom Install” radio button and click “Next”. You can select “Default” if you like to.
- Select “Software Localization” specific to your country and click “Next”.
- Select “System Locale” specific to your country.
- Select “Extra Value Software Software” and click “Next”.
- Select “None” for “Web Start Ready product scan location“
- Click “Next”, I made no changes and accepted the defaults.
- Confirm the disks are selected and click “Next”.
- Select fdisk Partitions to be customized, check mark the displayed disk and click “Next”
- Confirm the values and click “Next”.
- Layout File Systems, Highlight “c1t0d0” disk and click “Modify” to reflect the following values
- And Finally click “Install Now” which will begin the installation.The installation will take sometime to finish.
- Click “Reboot Now”
- Login using “SUN Console Login”
- You can use either “Java Desktop System” or “CDE”
- The installation is Complete, Solaris 10 Fresh Install is ready to be used.
Finally you might want to configure internet to your Solaris 10 VM, to do this do the following:
- If not already created, create file “/etc/defaultrouter” and enter your routers ip address
- If not already created, create file “/etc/resolv.conf” and enter the following:
search domainname nameserver default router address
- copy /etc/nsswitch.dns to /etc/nsswitch.conf
- Restart the network by issuing the following command:
#svcadm restart /network/dns/client
- Check the routing table and confirm the network is using the new sttings:
If not then add the default route by:
#route add default <gateway>
- Thats it you should be able to connect to the internet.
#ping google.com google.com is alive #
