Enterprise Manager Grid Control

Enterprise Manager Grid Control is Oracle's single, integrated solution for managing all aspects of the Oracle Grid and the applications running on it. Enterprise Manager also allows you to manage single instances of Oracle Database, Application Server, or Collaboration Suite using standalone consoles.

To compliment Oracle Enterprise Management Grid Control, Enterprise Manager Ops Center is Oracle's single, integrated solution for managing all aspects of the data center. It enables you to discover, provision, update, manage, and monitor the physical and virtual assets in one or more of your data centers from a single console.

Table 2-1 Installation Process for Installing Enterprise Manager System

Step 1	Installation of Oracle Management Service 11g Release 1 Creates an Oracle home in the Oracle Middleware Home location, and installs the Oracle Management Service (OMS) software binaries in the new home. Oracle Middleware Home consists of the Oracle WebLogic Server home, and, optionally, one or more Oracle homes. If the Oracle Middleware Home is /u01/app/Oracle/Middleware, then the Oracle home for OMS is /u01/app/Oracle/Middleware/oms11g
Step 2	Installation of Oracle Management Agent 11g Release 1 Creates an Oracle home in the Oracle Middleware Home location, and installs the Oracle Management Agent (Management Agent) software binaries in the new home. If the Oracle Middleware Home is /u01/app/Oracle/Middleware, then the Oracle home for Management Agent is /u01/app/Oracle/Middleware/agent11g
Step 3	Installation of Oracle Web Tier 11g Release 1 Creates an Oracle home in the Oracle Middleware Home location, and installs the Web tier software binaries in the new home. If the Oracle Middleware Home is /u01/app/Oracle/Middleware, then the Oracle home for Web tier is /u01/app/Oracle/Middleware/Oracle_WT
Step 4	Installation of Oracle Common Directory Creates a common directory in the Oracle Middleware Home location for storing configuration files. If the Oracle Middleware Home is /u01/app/Oracle/Middleware, then the common directory is /u01/app/Oracle/Middleware/oracle_common.
Step 5	Configuration of Oracle Management Service Instance Base Location Creates an instance home for Enterprise Manager Grid Control in the parent directory of the Oracle Middleware Home for storing all OMS-related configuration files. By default, the instance home is gc_inst. You can, however, edit this and specify a custom name. If the Oracle Middleware Home is /u01/app/Oracle/Middleware and if you choose to retain the default instance home name, then the instance home location is /u01/app/Oracle/gc_inst If the parent directory of the Oracle Middleware Home does not have write permission, then the OMS Instance Base is created in the Oracle Middleware Home.
Step 6	Configuration of Core Components Runs the Configuration Assistants to perform the following: Applying OMS-Related One-Off Patches: (Optional) Applies one-off patches to the Oracle home of the OMS (oms11g). Configuring SYSMAN Schema and MDS Schema: In the specified existing, certified Oracle Database, configures the SYSMAN schema and Metadata (MDS) schema, and creates these data files: mgmt.dbf, mgmt_ecm_depot1.dbf, mgmt_ad4j.dbf Configuring OMS: Configures the OMS and the independent instance where Enterprise Manager Grid Control is deployed. Add-on OMS Side Configuration: Configures the Virtualization Add-On detected in the Oracle home of the OMS (oms11g). Configures OCM (If Required): If you have chosen to configure Oracle Configuration Manager (OCM), then configures it in the Oracle home of the OMS (oms11g) and Oracle home of the Web tier (Oracle_WT). Applying Agent-Related One-Off Patches: (Optional) Applies one-off patches to the Oracle home of the Management Agent (agent11g). Configuring Management Agent: Configures the Management Agent to enable monitoring of targets, collection of information, and so on. Configures OCM (If Required): If you have chosen to configure Oracle Configuration Manager (OCM), then configures it in the Oracle home of the Management Agent (agent11g). Configures System Monitoring Plug-Ins: Configures the System Monitoring Plug-Ins detected in the Oracle home of the Management Agent (agent11g).
