Oracle® Enterprise Manager

Reviewing Information About This Guide

This guide describes how to perform a basic installation of Oracle Enterprise Manager Grid Control into a new database or into an existing database.

System Requirements

The system or systems must meet the minimum hardware and software requirements.

Even though Oracle Universal Installer runs prerequisite checks on your system to verify that it meets the listed requirements, to make sure that prerequisite checks do not fail, you should verify the requirements before running Oracle Universal Installer.

Mounting the Product Disk

On most Linux systems, the product disk mounts automatically when you insert it into the drive. If the disk does not mount automatically, follow these steps to mount it manually:

1. Switch user to "root" user:

   $ su - root
   
   

2. If necessary, eject the currently mounted disk and remove it from the drive. Use a command similar to the following, where /mnt/dvd and /media/dvd are the mount point directories for the disk drive:

   • Red Hat Linux: # eject /mnt/dvd

   • SUSE: # eject /media/dvd

3. Insert the disk into the drive.

4. To verify that the disk mounted automatically, change directory to the home directory and enter a command similar to the following:

   • Red Hat Linux: $ ls /mnt/dvd

   • SUSE: $ ls /media/dvd

     Note:

     Refer to OracleMetaLink's "Certify and Availability" page for additional information about these platforms.

5. If this command fails to display the contents of the disk, enter a command similar to the following:

   • Red Hat Linux:

     # mount -t iso9660 /dev/dvd /mnt/dvd
     
     

   • SUSE:

     # mount -t iso9660 /dev/dvd /media/dvd
     

Installing Oracle Enterprise Manager Grid Control

Once you have configured your system to meet hardware and software requirements, start Oracle Universal Installer (OUI) and install Grid Control as follows:

1. Start OUI by executing the following commands:

   1. Navigate to the home directory by entering the following command:

      cd <enter>
      

   2. Enter the following command:

      <mounted location>/Disk1/runInstaller
      
      

      For example: In Red Hat Linux, enter the command as follows:

      /mnt/dvd/Disk1/runInstaller
      
      

   Alternately, you can change directory to the Parent Directory (the root directory where you will install the Oracle home) and specify the full path to the runInstaller script.

2. The following table describes the recommended action for each OUI screen for the first two installation types.

   If you need more assistance, click Help on that screen. If you have trouble with the installation, check out the "Troubleshooting" chapter of Oracle Enterprise Manager Grid Control Installation and Basic Configuration.

   Installation Screen	Recommended Action
   Specify Installation Type	Select one of the installation types provided. The complete installation type is chosen by default.
   Specify Installation Location	Specify the "parent" directory location for the installation. All Oracle homes created during installation will be placed as subdirectories under the parent directory.
   Language Selection	Select the languages to run Grid Control in. The language you specify here is not the language of the installation session.
   Specify Inventory Directory and Credentials	Appears only during the first installation of Oracle products on a system. Specify the full path of the Oracle Inventory directory. Make sure to select the appropriate operating group.
   Product-Specific Prerequisite Checks	Verify that all prerequisite checks succeed. OUI checks the system to verify that it is configured correctly to support your Oracle software. If you have met all hardware and software requirements in this guide, all of the checks should pass. If a check fails, review the cause of failure, rectify the problem, and retry the check. You can also choose to manually verify failed checks if you are satisfied that your system meets the requirements.
   Specify Configuration	Appears only for the "Enterprise Manager Grid Control Using a New Database" installation type. Specify the name of the database you want to create, as well as the location to store the Management Repository files. Choose a file location outside of the Oracle home. Select the OSDBA and OSOPER groups that you are a member of. These memberships are required to grant the SYSDBA and SYSOPER privileges required to create the new database.
   Specify Repository Database Configuration	Appears only for the "Enterprise Manager Grid Control Using an Existing Database" installation type. Specify the database connection details for your existing, qualified database, as well as the locations for the new Management Repository tablespaces.
   Specify Optional Configuration	All parameters can be configured through Grid Control after installation. If you want, set the parameters for email notification, OracleMetaLink credentials, and proxy configuration settings.
   Specify Security Options	Appears only for the "Enterprise Manager Grid Control Using a New Database" installation type. Specify password used to secure the Management Service, as well as passwords to secure the Management Repository Database.
   Specify Passwords	Appears only for the "Enterprise Manager Grid Control Using an Existing Database" installation type. Specify the password used to secure the Management Service, as well as the SYSMAN password.
   Summary	Review the information displayed here, then click Install.
   Install	This screen displays status information while the product is being installed.
   Execute Configuration Scripts	When prompted, read the instructions and run the scripts listed here. You must run the scripts as root from a terminal window.
   Configuration Assistants	Displays status information for configuration assistants
   End of Installation	Contains important information about your installation, including the URLs configured for your applications. Make a note of these URLs. The port numbers used in these URLs are recorded in the following file: $ORACLE_HOME/install/portlist.ini

   
   

Other Installation or Upgrade Options

In addition to performing a complete Grid Control installation, either using the embedded database or an existing, qualified one, you can perform the following other installation or upgrade operations:

• Install an additional Management Service.

• Install Management Agents using the Agent Deployment application. This application is part of the Grid Control installation, and can be used to "push" Management Agents from a central location to one or more target hosts in a single operation. Before launching a deployment operation using this method, you must set up SSH connectivity between the Management Service host and all target hosts. To do so, execute the script found at:

  <OMS ORACLEHOME>/sysman/prov/resources/scripts/      sshUserSetup.sh
  
  

  To initiate a deployment operation, click the Install Agent link on the Grid Control Deployments page. For more details, refer to the "Installing the Management Agent Using Agent Deploy" section in Oracle Enterprise Manager Installation and Basic Configuration.

• Install Management Agents using the agentDownload script. Launch this script on each target host to "pull" files from a central staging location. The requirements for the agentDownload script are:

  1. The agentDownload script must have execute permission. After you have downloaded the script, change the file permissions as follows:

     chmod +x agentDownload.linux
     
     

  2. Ensure that the "jar" command and "wget" is in the system PATH.

  To download and run the agentDownload script:

  1. Log into the target host.

  2. Bring up the browser window.

  3. Download the agentDownload script from:

     http://mgmthost27.acme.com:4889/agent_download/10.2.0.1.0/<OS>/agentDownload .<OS>

  4. Navigate to the directory where the agentDownload script is available.

  5. Change the file permissions as follows:

     chmod +x agentDownload . <OS>
     
     

  6. Execute the agentDownload script as follows:

     run agentDownload . <OS>
     
     

     For example:

     /agentDownload.linux -b /scratch/agentInstall
     
     

     You can use the -h option to see the usage details.

• Upgrade a previous, qualified version of Enterprise Manager Grid Control. Existing versions of Enterprise Manager will be automatically detected.

Refer to Oracle Enterprise Manager Grid Control Installation and Basic Configuration for detailed information and instructions on all of the above operations.
