Concepts
• Enterprise Manager Cloud Control Console
– The user interface you see after you install Enterprise Manager Cloud Control
• Oracle Management Service (OMS)
– Orchestrates with the Management Agents and the Plug-Ins to discover targets
• Oracle Management Repository (Management Repository)
– Storage location where all the information gets stored
• Oracle Management Agent (Management Agent)
– The Management Agent works in conjunction with the plug-ins to monitor the targets running on that managed host.
• Plug-Ins
– Plug-Ins are pluggable entities that offer special management capabilities customized to suit specific target types

Fast track
• oracle-rdbms-server-11gR2-preinstall RPM
– (formerly known as oracle-validated)
• The pre-install package is available for x86_64 only. Specifically, the package:
– Causes the download and installation of various software packages and specific versions needed for database
installation, with package dependencies resolved via yum
– Creates the user oracle and the groups oinstall and dba, which are the defaults used during database installation
– Modifies kernel parameters in /etc/sysctl.conf to change settings for shared memory, semaphores, the maximum
number of file descriptors, and so on
– Sets hard and soft shell resource limits in /etc/security/limits.conf, such as the number of open files, the number of
processes, and stack size to the minimum required based on the Oracle Database 11g Release 2 Server installation
requirements
• +glibc-devel.i686, + Yum update
