FOOD PREPARATION TIPS AND USEFUL INFORMATION: Installing The Grid Control

We need to install the Grid control by downloading the software from Oracle's web site or by using the appropriate CD. Installing Grid Control consists of two steps: 1) Installing the OEM Grid Control software on the host from which we intend to use the Grid Control console. 2) Installing the Management Agent on each of the hosts we want to monitor. Installing the Grid Control Component : Installing Grid Control is similar to the installing of Oracle Server software. We must make sure we have the DISPLAY variable set up properly if we're using a UNIX/Linux system. Steps in the Installation Process: 1) Log in to the host as the Oracle software owner and mount the Oracle database 10g CD. Change directory to the CD, and execute the runInstaller script. $ ./runInstaller 2) At the Welcome window, click Next 3) Accept the default operating system(OS) group name. Click Next 4) A seperate window asking us to run the root.sh UNIX script will appear. Leave this window open, and open a new terminal window 5) Execute orainstRoot.sh as the root user in the terminal window, as shown here: $ cd $ORACLE_BASE/oraInventory $ su $ $ ./orainstRoot.sh $ exit 6) Once we run the orainstRoot.sh script, we have to go back to the Oracle Universal Installer window and click Continue 7) In the specify File Locations window, choose the directory for the OEM files and click Next 8) In the select a product to install window we can install the OEM Grid Control in an existing Oracle database or we can create a new database. We can also choose to install a Management Service or Management Agent from this window. Click Next. When we choose to install the grid Control using a new database, Oracle will create a ew Oracle Database 10g database on our server. If we wnt to install using an existing Oracle database, our database must be version 9.2 or higher. 9) The Oracle Universal Installer will make the necessary prerequisite checks, after which we click Next 10) Choose a password for the default SYSMAN user and click Next 11) Select passwords for the SYS,SYSTEM and DBSNMP users in the new database and click Next 12) In the next window, we have the option of setting up the MetaLink and Proxy information. These are optional and have no bearing on the functioning of Grid Control. Once we makeur choice, click Next 13) In the Database Identification window that appears next, choose the SID and the Global Database Name for the database. Click Next 14) In the Database File location window, specify the location for all the database files and click Next 15) Review the list of components that are going to be installed in the Summary screen that appears , and click Install 16) We'll now see a series of windows indicating the progress of the installation. We'll be asked to run the root.sh script again as the root user. Log in as root user in a seperate window and run the root.sh script again as a root user. Log in as a root user in a seperate window and run the root.sh script. Then go back to the installation window and click OK 17) The Configuration Assistant window will show the status of the various configuration assistants, such as the Oracle Database Configuration Assistant. There can be n(n=1...any) configuration assistants in a system. After the new oracle database is created, we'll see the following message: The Oracle Agent will now be installed on the same machine as the database that was just created. This database will then be available through Grid Control to manage its environment. Click OK. 18) When the Setup privileges window appears, open a new terminal window and run the orainstRoot.sh script yet again. Once the script completes, go back to the installer window and click Next. The Configuration assistants window will appear again and the Agent Configuration Assistant will install the Oracle Agent. 19) We'll see an end of installation message from the Installer, along with the list a port numbers we can use to access the Grintrol., the Oracle Application server that's instaled as a part of the Grid Control installation, and the Oracle database that was created to host theGrid Control 20) Click Exit to end the installation Installing and Deploying the OEM Management Agent : Use the following steps to install the OEM Management Agent on each server we want to monitor: 1-7 ) Start the Oracle Universal Installer and perform the first seven steps as in the preceding section. 8) In the select a Product window, choose the Additional Management Agent installation type and click Next 9) Specify the name of our host server in the next page and click Next 10) click Next, after reading the security warning (regarding secure HTTP mode) and then click OK 11) Review the summary window and click Next to start the actual agent installation process 12) Once our installation completes, click Yes to exit the Oracle Universal Installer 13) Verify that our databases and hosts can be seen by the newly installed Management Agent. we can do this by logging in to the Grid Control and clicking the Targettab. We'll see all the discovered hosts. Click on any host and then click on databases. We should now be able to view all our Oracle databases that are running on that host. Once we successfully install the agents on our servers , we can use the information they collect to monitor all our oracle databases, hosts, web servers and listeners.
