# Mount the Oracle Enterprise Manger Grid Control Disk

Switch to user root
su - root

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

#Install OEM Grid Control

a. Go to Disk1 under the mounted location (OEM Proudct DVD) and Run the installer

- Language Selection => languages to run Grid Control in.Selection of language at this point is for installation session.
- Inventory Directory and Credentials=> This option will populate only once on your first installation of Oracle products.
- Product-Specific Prerequisite Checks => This will check all Hardware and software requirement to configure Oracle Software.
- Specify Configuration=> This option populate only for "Enterprise Manager Grid Control Using a New Database". At this point you can specify Database name,location of Management Repository files. Select location which is outside to your ORACLE_HOME.Select at this point two groups which required to grant SYSDBA and SYSOPER privileges required to create new database (OSDBA,OSOPERgroup).
- Specify Repository Database Configuration =>This option will populate only for "Enterprise Manager Grid Control Using an Existing Database". You can specify here Database connection details of your existing database,also locations of the new Management Repository tablespaces. - Specify Optional=> You can configure these option after Grid control installation like email,Oracle metalink credentials and proxy configuration settings.
- Configuration,Security Options=> This will populate only for "Enterprise Manager Grid Control Using a New Database". Specify password to secure the Management service and the management repository database.
