This chapter provides information that helps you prepare better for an Enterprise Manager Grid Control installation. This chapter contains the following sections:
First-Time Installation of Oracle Enterprise Manager Grid Control
Why Do I Need to be Able to Log In as Root at Certain Times During Installation?
You can download the Enterprise Manager software from the Oracle Technology Network (OTN):
http://www.oracle.com/technology/documentation.
All OTN files have been archived using Info-ZIP's highly portable Zip utility. After downloading one or more of the archives, you will need the UnZip utility to extract the files. You must unzip the archive on the platform for which it was intended.
For example, if you download the file for the Linux Operating System version of Oracle Enterprise Manager, you must unzip the file on a Linux Operating System computer. If you unzip the file on a Windows computer, and then move the stage area to a Linux Operating System machine, the stage area files will be corrupted because Windows does not preserve the case sensitivity or the permission bits of Linux file names.
Verify that the file size of your downloaded file matches the file size displayed on OTN. Unzip each Zip file to its own temporary directory. For example, create a directory structure called instEM10g on your hard drive:
/instEM10g
Then create a new directory for each Zip file you downloaded:
/instEM10g/<DVD> /instEM10g/<DVD>
If you plan to burn the files on a DVD-ROM, create a separate DVD-ROM from the contents of each directory. Do not burn a DVD-ROM containing the Zip file itself; you need the unzipped contents of the Zip files to do the installation. When you burn the files to DVD-ROM, the contents of each disc must be at the root of the DVD image.
The directories in which you install Oracle Enterprise Manager components are called the Oracle homes. During installation, you specify the full path to a directory that contains all the Oracle homes as sub-directories. This parent directory is called the Oracle Home Directory or Base directory.
If you choose to install Enterprise Manager Grid Control using a New Database on a computer with no other Oracle software installed, Oracle Universal Installer creates an Oracle base directory for you. If Oracle software is already installed, then one or more Oracle base directories already exist. In the latter case, Oracle Universal Installer offers you a choice of Oracle base directories into which to install the Oracle Database.
You are not required to create an Oracle base directory before installation, but you can do so if desired. You can set the ORACLE_BASE environment directory, which Oracle Universal Installer will recognize.
|
Note: You can choose to create a new Oracle base directory, even if other Oracle base directories exist on that system. |
Names of Oracle homes must be 128 characters or fewer, and can contain only alphanumeric characters and underscores.
|
ATTENTION: Spaces are not allowed anywhere in the Oracle home directory path. The installer validates this. If you have spaces in the Oracle home directory path, the installation will fail. |
Generally, you cannot install Oracle Enterprise Manager in an existing Oracle home, unless the Oracle home is empty.
If Enterprise Manager Grid Control is the first Oracle product that you are installing on a machine, the installer prompts you to specify an inventory directory (also called the oraInventory directory). This inventory directory is used by the installer to place all the installer files and directories on the computer. The installer automatically sets up sub-directories for each Oracle product to contain the inventory data.
The inventory directory is separate from the Oracle home directory.
When you specify the Oracle Inventory Directory path, you must also select the appropriate Operating System group name that will own the Oracle Inventory Directories. The group that you select must have write permissions on the Oracle Inventory directories.
If you have a previous version of Enterprise Manager installed on the computer, the installer uses the existing inventory directory. Ensure that you have write permissions on that directory. The best way of ensuring this is to run the installer as the same operating system user who installed the existing version of Enterprise Manager Grid Control.
By default, the installer installs Oracle Enterprise Manager with text in English and in the operating system language. If you need additional languages, select the required Languages in the Select Languages page of the installer.
When you select additional languages to install, the installer installs text in the selected languages. It also installs fonts required to display the languages.
For some components, languages are installed only if you select them during installation. In this case, if you access the application in a language that is not available, it reverts to the server locale language.
For other components, available languages are installed regardless of what you select during installation. In this case, however, fonts are installed only for the languages that are explicitly selected. When you access the application, it uses text in your language because the language was installed. However, if you do not have the appropriate fonts to render the text, the text appears as square boxes. This usually applies to the Chinese, Japanese, and Korean languages.
The installer prompts you to specify the passwords that are used to secure your entire Grid Control environment. This includes the Management Service and database repository passwords. One of the database passwords that you specify is the password required to access the application server (ias_admin). The ias_admin user is the administrative user for Oracle Application Server instances. To manage Oracle Application Server instances using Application Server Control, you must log in as ias_admin. Ensure the passwords you specify have all the required permissions.
Password Restrictions
The following restrictions apply to passwords:
Passwords must be between 5 and 30 characters long.
Passwords cannot be the same as the user name.
Passwords must only include lowercase or uppercase alphanumeric characters.
|
Note: The SYSMAN password can include underscore (_), and hypen (-) along with alphanumeric characters. Alpha characters can be lowercase or uppercase. |
Passwords cannot be Oracle reserved words. See Appendix H, "Oracle Reserved Words" for a complete list of reserved words.
Oracle recommends that the passwords that you specify are not simple or obvious words, such as welcome, account, database, or user.
At least once during installation, the installer prompts you to log in as the root user and run a script. You need to log in as root because the script edits files in the /etc directory.
On most Linux systems, the disk mounts automatically when you insert it into the disk drive. To mount the first disk, follow these steps:
Insert Oracle Enterprise Manager disk 1 into the disk drive.
To verify that the disk mounted automatically, enter the following command:
Red Hat Enterprise Linux:
# ls /mnt/dvdrom
SUSE Linux Enterprise Server:
# ls /media/dvdrom
If the command in step 2 fails to display the contents of the disk, enter the following command:
Red Hat Enterprise Linux:
# mount -t nfs <host name>:/mnt/dvdrom
SUSE Linux Enterprise Server:
# mount -t nfs <host name>:/media/dvdrom
If your computer does not mount DVDs automatically, you need to set the mount point manually.
DVD-ROM users: Insert the Oracle Enterprise Manager Grid Control DVD-ROM into the DVD-ROM drive.
Start the Oracle Universal Installer by executing the runInstaller script for Linux from the top directory of the DVD.
Alternatively, you can change the directory to the ORACLE_BASE, the root directory where you will install the Oracle home, then specify the full path to <DVD>/runInstaller in OUI.
DVD-ROM
prompt> cd
prompt> mount_point/10.2<DVD>/runInstaller
This launches Oracle Universal Installer through which you install Enterprise Manager Grid Control.
When you perform an Enterprise Manager installation, this installation does not include the Enterprise Manager Configuration Plug-in (EMCP) in the database Oracle home. EMCP is part of the repository database Oracle home only when you perform a standalone database installation.
