Installing 11.1 Enterprise Manager Grid Control October 23, 2010

Grid Control 11g interface may have the same look and feel as the Grid Control 10g, but under the hood it is quite different. In version 10g, the OMS was a J2EE (OC4J) application deployed on the Oracle Application Server. Whereas in version 11g, the OMS is deployed on Web Logic Server (WLS) .

For this post, I have provided some simple steps on how to install the Grid Control with minimal pain.

The table below lists the configuration that will be used for the following demonstration.

* SYSMAN is actually the application schema created in the GC. This is also the super administrator for logging into the EM Console.

SECTION 1 –PRE- INSTALLION TASKS

1. Verify the OS platform and supported Database version for the Grid Control Repository that is intended to be installed is supported. See My Oracle Support Note 412431.1 for further details.

2. Install the Database software and create a Database for the Grid Control Repository. A good example can be found here:

http://blog.ronnyegner-consulting.de/2009/09/14/oracle-11g-release-install-guide-install-single-database
NOTE: When creating the database do not configure Enterprise Manager during this step.

3. As per Grid Control installation manual, make sure the pre-requisites are met as mentioned at:

http://download.oracle.com/docs/cd/E11857_01/install.111/e15838/install_em_exist_db.htm#CIAIEAAC

NOTE: For this exercise, the repository was created on mama.earth.com and service name is GCREP

SECTION 2 – INSTALL JDK SOFTWARE

4. Download JDK 1.6 (6.0) from http://java.sun.com/products/archive/

NOTE: According to My Oracle Support Note 1063762.1 make sure that the JDK version 1.6 Update 18 is used for installation of WebLogic on Linux 64-bit (x86_64) platform.

5. Create the base directory for JDK and copy the file jdk-6u18-<os_platform>.bin to the new directory.

oracle@oem[]$ mkdir -p /u01/jdk16
oracle@oem[]$ cp –rp jdk-6u18-linux-x64.bin /u01/jdk16

6. Run the JDK installation

oracle@oem[]$ cd /u01/jdk16
oracle@oem[]$ ./jdk-6u18-linux-x64.bin

7. Reivew the License Agreement and then click on <SPACE BAR> to continue until the following prompt is reached:

Do you agree to the above license terms? [yes or no]

8. Type yes to continue

yes

9. Click on <ENTER> to continue

Press Enter to continue.....

10. This should now complete the installation for JDK.

11. Verify that the new JDK directory jdk1.6.0_18 has been created.

oracle@oem[]$ ls
jdk1.6.0_18

SECTION 3 – WEBLOGIC INSTALLATION

1. Download WebLogic Server software from http://www.oracle.com/technology/software/products/ias/htdocs/wls_main.html

NOTE: For this example, the installation will be performed on linux 64-bit platform, hence the Generic file version will be downloaded. If running windows (32bit – x86) or Sun (64bit – SPARC) then please download the alternative as listed below.

2. Set Local Display and then run via an X session to host:

oracle@oem[]$ xhost +
oracle@oem[]$ ssh <weblogic_host>
oracle@oem[]$ export DISPLAY=<LOCAL_DISPLAY>:<DISPLAY_NO>

Example:

oracle@oem[]$ xhost +
oracle@oem[]$ ssh oem.earth.com
oracle@oem[]$ export DISPLAY=laptop:0

3. Set JAVA Home to where the JDK installation path and then run the WebLogic Installer

oracle@oem[]$ export JAVA_HOME=/u01/jdk16/jdk1.6.0_18
oracle@oem[]$ $JAVA_HOME/bin/java -d64 -jar wls1032_generic.jar

4. The WebLogic Installer screen now appears, to continue click on Next.

5. Enter a new Middleware Home Directory (eg. /u01/app/oracle/Middleware) and then click on Next.

6. Register for Security Updates, leave default and click on Next.

7. To continue click on Yes, if you wish to ignore setup for notification of security updates.

8. To skip configuration and continue to ignore setup for notification of security updates click on Yes.

9. Select Typical for the installation type to perform and then click on Next.

10. Leave default options selected for Products and Components and then click on Next.

11. Verfy the JDK installed has been detected by the Oracle Installer for WebLogic and then click on Next.

12. Verify the default Product Home for WebLogic Server (eg. /u01/app/oracle/Middleware/wlserver_10.3) and the click on Next.

13. Review the Installation Summary and click on Next.

14. Installation is now in progress …. Please wait

15. Installation is now complete, deselect the option Run Quickstart and then click on Done.

SECTION 4 – WEBLOGIC WDJ7 PATCH INSTALLATION (USING SMART UPDATE)

It is strongly recommended that the Weblogic patch WDJ7 patch is applied before installing the Grid Control 11g software.

1. Set the JAVA_HOME:

oracle@oem[]$ export JAVA_HOME=/u01/jdk16/jdk1.6.0_18

2. Change directory to the BSU utility directory:

oracle@oem[]$ cd /u01/app/oracle/Middleware/utils/bsu
oracle@oem[]$ ./bsu.sh

3. Enter My Oracle Support* User Credentials.
NOTE: * Requires a valid support profile registered with http://support.oracle.com

4. Please wait as eSupport validates the user credentials.

5. This will refresh the library of patches available for download.

6. Complete registration for security updates or you may ignore and click on Continue.

7. To continue click on Yes, if you wish to ignore setup for notification of security updates

8. To skip configuration and continue to ignore setup for notification of security updates click on Yes.

9. The Smart Update Screen should now appear. Go to the Get Patches tab and select the WDJ7 patch and then click on Download Selected.

NOTE: Highlight Patches from the top menu and then select on Refresh View to get the latest listing of patches available for download.

10. Say Yes, to check for conflict of each patch and then click on Ok.

11. Please wait for validation to be completed and then click on Ok.

12. The WDJ7 patch has now downloaded.

13. Click on the Manage Patches, Then click on the button for WDJ7 patch located under the Apply column.

14. Review Oracle Support notice information regarding patches, and then click on Ok to continue.

15. Please wait for validation to be completed and then click on Ok.

16. The patch should now appear in the top window of the Manage Patches tab. This verifies that the patch WDJ7 has been applied successfully.

17. This completes the patch update and the Smart Update program for WebLogic can be closed. Click on File and then on Exit.

SECTION 5 – Install Grid Control Software

1. Downloaded the software for 11gR1 Grid Control from:

http://www.oracle.com/technetwork/oem/grid-control/downloads/index.html

(NOTE: Under the Full Installers (Agent,Repository, OMS and Management Packs) section, download for the appropriate files for your platform. In this demonstration the Linux 64 bit version will be the example used.)

2. Extract all files in the same directory where the files were downloaded to:

oracle@oem[]$ unzip GridControl_11.1.0.1.0_Linux_x86-64_1of3.zip
oracle@oem[]$ unzip GridControl_11.1.0.1.0_Linux_x86-64_2of3.zip
oracle@oem[]$ unzip GridControl_11.1.0.1.0_Linux_x86-64_3of3.zip

3. Set Local Display and then run via an X session to host:

oracle@oem[]$ xhost +

oracle@oem[]$ export DISPLAY=<LOCAL_DISPLAY>:<DISPLAY_NO>

Example:

oracle@oem[]$ xhost +
oracle@oem[]$ ssh oem.earth.com
oracle@oem[]$ export DISPLAY=laptop:0

4. In the same directory where files were extracted to, execute the runInstaller to launch the Grid Control Installation Wizard:
Option 1
Run with no variable set:

oracle@oem[]$ cd install
oracle@oem[]$ ./runInstaller

Option 2
If the server has multiple hostname or alias of where the Grid Control installation is to be installed to, the ORACLE_HOSTNAME can be used to forced the Grid Control to use the preferred name

oracle@oem[]$ ./runInstaller ORACLE_HOSTNAME=<PREFERRED_NAME>

For example:

oracle@oem[]$ ./runInstaller ORACLE_HOSTNAME=oem.earth.com

5. The Grid Control Installer screen now appears.

6. Register for Security Updates or leave default and click on Next.

7. To continue click on Yes, if you wish to ignore setup for notification of security updates
