Deploying Oracle Enterprise Manager 11g Grid Control

New in 11g Install  Overview

• Installer is more User friendly and Intuitive
• It’s a full release, so no burden of installing a base release and then patching it to the latest version
• Enhanced pre-requisite checks ,Better input validations and show errors along with the recommendations
• Auto Update – Provides ability to apply install updates and product updates during/after the installation (e.g. new pre-requisites, patchsets or one-off patches)
• Allows to select secure/unsecure communication from the OMS during the Install
• Custom port assignment before installation
• Based on WebLogic stack

The add-ons are independent of Enterprise Manager Grid Control and additional OMS, and if you want to continue to use them, then you must first upgrade the software binaries of the existing Enterprise Manager Grid Control or additional OMS, then install the add-ons, and then finally configure the upgraded software binaries of Enterprise Manager Grid Control or additional OMS.

Some of the important directories for the 11g instance home are:
Instance Home/em: This directory stores the deployed Grid Control application files, including:
EMGC_OMS1/sysman/config: The config directory contains configuration files for online help, certificates used for OMS/agent communication and place holder properties files pointing users to emctl commands. NOTE: None of these files are end-user modifiable.
EMGC_OMS1/sysman/log: The log directory contains log and trace files for the OMS, including emoms.log and emoms.trc
EMGC_OMS1/sysman/ocm: The ocm directory contains properties files used for passing OMS configuration properties to the OCM. NOTE: The files in this directory are not end-user modifiable.
Grid Control Installation Directories: Instance Home (continued)
Instance Home/user_projects: This is a WLS artifact which contains the WLS specific configuration files under the domains directory for the Grid Control domain created when Grid Control was installed (GCDomain), including:
domains/GCDomain/bin: The bin directory contains files used to start the Grid Control domain
domains/GCDomain/config: The config directory contains configuration files for the Grid Control domain
domains/GCDomain/servers: The servers directory contains the managed server logs under servers/EMGC_OMS1/logs
Instance Home/WebTierIH1: This directory stores Apaches specific files, including:
bin: The bin directory contains the opmnctl utility, used to stop, start and get process status for the process monitor and notification server
config: The config directory contains Apache configuration files
diagnostics: The diagnostics directory contains Apache diagnostic and log files
NOTE: Instance_home/user_projects/applications is still created but not listed not on the slide as it is no longer used. It will be removed in a later release.

1. Need WebLogic Server (WLS) up and running

   • WLS version should be 10.3.2 only!
   • The WLS install should be of type “TYPICAL”
   • WLS should be patched with the patch ID WDJ7 before installing Grid Control
   • For 64-bit platforms, JDK needs to be installed

2. Need an existing certified Database to house the Grid Control Repository

   • Database to be of certified version, Refer Certification Note 412431.1
   • Shouldn’t have Database Control SYSMAN schema
   • Initialization parameters are set in the database as per the Install guide.
