This chapter describes new features in the Enterprise Manager 10g Release 2 (10.2) installer.
The new Enterprise Manager installer provides an installation that is almost completely automated. In this release, the Enterprise Manager installer also provides the following:
Renders seamless multiple-Oracle home installations and configurations during a single session.
Facilitates individual maintenance cycles for each of the top-level product components.
This is brought about by installing the database and the Oracle Management Server (OMS) in separate Oracle homes. In this release, the Enterprise Manager installer will perform a chain install, wherein it will install the OMS, database, and the agent in separate Oracle homes (oms10g
, db10g
, and agent10g
).
Facilitates a Grid Control upgrade from 10.1.x release patchsets to 10.2.
Facilitates mass deployment of the Management Agent using the Agent Deploy application.
Provides an out-of-box secure Enterprise Manager Grid Control environment.
Provides automated startup scripts that help start the database, Management Service, listener, and the Management Agent during a machine reboot.
Allows the user to resume the installation process from the point where it was aborted, through the built-in resumability feature of the installer.
The Enterprise Manager installer provides for a seamless installation experience by performing multiple Oracle home installations, depending on the type of installation that is selected.
A typical Oracle Enterprise Manager installation will create a separate Oracle home for:
Oracle Management Service
Oracle Database
Oracle Management Agent
Note: The Oracle homes that are created as sub-directories by the installer will be placed under the Parent Directory that you specify. The Oracle homes will be created asdb10g , oms10g , and agent10g .
|
The Enterprise Manager installer performs seamless multiple Oracle home configurations during the installation process. The configuration tools that are run during installation will depend on the installation type that you have selected.
The following table lists all the configuration tools that are run during a typical Enterprise Manager installation (Install Enterprise Manager Using a New Database):
Product | Configuration Tools |
---|---|
Oracle Enterprise Manager Repository Database |
|
Oracle Enterprise Manager Grid Console |
|
Oracle Management Agent |
|
Note: Depending on the Install Type you have chosen, any or all of the configuration tools listed in the table above will be run. |
You are now required to run only one script allroot.sh,
in this release of the installer, as compared to the three root.sh
scripts (one for each Oracle home) that you had to run in the previous release.
Note: If Enterprise Manager is the first Oracle product that you are installing, you will also be prompted to executeorainstRoot.sh along with allroot.sh .
|
In the event of an unexpected termination of the installation process, the Resumability feature of the Installer allows you to resume the installation process (the next time the Installer is invoked) from the point where the installation was aborted.
The new Enterprise Manager 10g R2 installer provides a secure Grid Control environment out-of-box.
In this release of Enterprise Manager, the startup scripts to run the database, Management Service, listener, and agent are automatically executed in case a machine reboots. The services that are automatically started depend on the installation type that you have chosen.
Installing | Automated Scripts Start the |
---|---|
Enterprise Manager Using New Database | Repository database, listener, Management Service, and the agent. |
Enterprise Manager Using Existing Database | Management Service and agent. |
Additional Management Service | Management Service and agent. |
Additional Management Agent | Agent only. |
The Enterprise Manager 10g R2 Installer's enhanced GUI provides for a more user-friendly installation experience.
After you select the appropriate installation option in the first screen (Specify Installation Type), you will be prompted to specify the Parent Directory in the Specify Installation Location screen, wherein the Oracle homes are created automatically.
The Specify Configuration screen for installing Enterprise Manager using an existing database has changed. The single Connect String value (comprising of host name, port, and SID) that you had to specify in the previous release has been changed to three input fields.
This page has been removed. You can now select the required languages by clicking Product Languages in the Installation Location screen.
The Specify Repository Database Configuration screen now includes the Prefill Tablespace Locations button. On clicking this button, the installer queries the database that you have specified, looks for the SYSAUX
tablespace location, and automatically prefills that path in the appropriate tablespace location text boxes.
Note: If the tablespaces are stored in a raw device/ASM disk, then you must ensure the raw device/ASM disk is accessible to store the SYSMAN tablespaces. |
