• 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

Requirements

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
