4 Installing Oracle Grid Infrastructure for a Cluster

This chapter describes the procedures for installing Oracle Grid Infrastructure for a cluster. Oracle Grid Infrastructure consists of Oracle Clusterware and Oracle Automatic Storage Management (Oracle ASM). If you plan afterward to install Oracle Database with Oracle Real Application Clusters (Oracle RAC), then this is phase one of a two-phase installation.

This chapter contains the following topics:

4.1 Preparing to Install Oracle Grid Infrastructure with OUI

Before you install Oracle Grid Infrastructure with the installer, use the following checklist to ensure that you have all the information you will need during installation, and to ensure that you have completed all tasks that must be done before starting your installation. Check off each task in the following list as you complete it, and write down the information needed, so that you can provide it during installation.

4.2 Installing Grid Infrastructure

This section provides you with information about how to use the installer to install Oracle Grid Infrastructure. It contains the following sections:

4.2.1 Running OUI to Install Grid Infrastructure

Complete the following steps to install Oracle Grid Infrastructure (Oracle Clusterware and Oracle Automatic Storage Management) on your cluster. At any time during installation, if you have a question about what you are being asked to do, click the Help button on the OUI page.

  1. Change to the /Disk1 directory on the installation media, or where you have downloaded the installation binaries, and run the runInstaller command. For example:

    $ cd /home/grid/oracle_sw/Disk1
    $ ./runInstaller
    
  2. Select Typical or Advanced installation.

  3. Provide information or run scripts as root when prompted by OUI. If you need assistance during installation, click Help. Click Details to see the log file. If root.sh fails on any of the nodes, then you can fix the problem and follow the steps in Section 6.5, "Deconfiguring Oracle Clusterware Without Removing Binaries," rerun root.sh on that node, and continue.

    Note:

    You must run the root.sh script on the first node and wait for it to finish. If your cluster has four or more nodes, then root.sh can be run concurrently on all nodes but the first and last. As with the first node, the root.sh script on the last node must be run separately.
  4. After you run root.sh on all the nodes, OUI runs Net Configuration Assistant (netca) and Cluster Verification Utility. These programs run without user intervention.

  5. Oracle Automatic Storage Management Configuration Assistant (asmca) configures Oracle ASM during the installation.

When you have verified that your Oracle Grid Infrastructure installation is completed successfully, you can either use it to maintain high availability for other applications, or you can install an Oracle database.

If you intend to install Oracle Database 11g release 2 (11.2) with Oracle RAC, then refer to Oracle Real Application Clusters Installation Guide for Linux.

Oracle Clusterware Administration and Deployment Guide for cloning Oracle Grid Infrastructure, and Oracle Real Application Clusters Administration and Deployment Guide for information about using cloning and node addition procedures for adding Oracle RAC nodes

4.2.2 Installing Grid Infrastructure Using a Cluster Configuration File

During installation of Oracle Grid Infrastructure, you are given the option either of providing cluster configuration information manually, or of using a cluster configuration file. A cluster configuration file is a text file that you can create before starting OUI, which provides OUI with information about the cluster name and node names that it requires to configure the cluster.

Oracle suggests that you consider using a cluster configuration file if you intend to perform repeated installations on a test cluster, or if you intend to perform an installation on many nodes.

To create a cluster configuration file manually:

  1. On the installation media, navigate to the directory /response.

  2. Using a text editor, open the response file grid_install.rsp.

  3. Follow the directions in that section for creating a cluster configuration file.

The following is a list of additional information to note about installation:

  • If you are installing on Linux systems, you are using the ASM library driver (ASMLIB), and you select Oracle Automatic Storage Management (Oracle ASM) during installation, then Oracle ASM default discovery finds all disks that ASMLIB marks as Oracle ASM disks.

4.3 Installing Grid Infrastructure Using a Software-Only Installation

This section contains the following tasks:

Note:

Oracle recommends that only advanced users should perform the software-only installation, as this installation option requires manual postinstallation steps to enable the Oracle Grid Infrastructure software.

A software-only installation consists of installing Oracle Grid Infrastructure for a cluster on one node.

If you use the Install Grid Infrastructure Software Only option during installation, then this installs the software binaries on the local node. To complete the installation for your cluster, you must perform the additional steps of configuring Oracle Clusterware and Oracle ASM, creating a clone of the local installation, deploying this clone on other nodes, and then adding the other nodes to the cluster.

See Also:

Oracle Clusterware Administration and Deployment Guide for information about how to clone an Oracle Grid Infrastructure installation to other nodes, and then adding them to the cluster

4.3.1 Installing the Software Binaries

To perform a software-only installation:

  1. Run the runInstaller command from the relevant directory on the Oracle Database 11g release 2 (11.2) installation media or download directory. For example:

    $ cd /home/grid/oracle_sw/Disk1
    $ ./runInstaller
    
  2. Complete a software-only installation of Oracle Grid Infrastructure on the first node.

  3. When the software has been installed, run the orainstRoot.sh script when prompted.

  4. The root.sh script output provides information about how to proceed, depending on the configuration you plan to complete in this installation. Make note of this information.

    However, ignore the instruction to run the roothas.pl script, unless you intend to install Oracle Grid Infrastructure on a standalone server (Oracle Restart).

  5. On each remaining node, verify that the cluster node meets installation requirements using the command runcluvfy.sh stage -pre crsinst. Ensure that you have completed all storage and server preinstallation requirements.

  6. Use Oracle Universal Installer as described in steps 1 through 4 to install the Oracle Grid Infrastructure software on every remaining node that you want to include in the cluster, and complete a software-only installation of Oracle Grid Infrastructure on every node.

    Configure the cluster using the full OUI configuration wizard GUI as described in Section 4.3.2, "Configuring the Software Binaries," or configure the cluster using a response file as described in section Section 4.3.3, "Configuring the Software Binaries Using a Response File."

4.3.2 Configuring the Software Binaries

Configure the software binaries by starting Oracle Grid Infrastructure configuration wizard in GUI mode:

  1. Log in to a terminal as the Grid infrastructure installation owner, and enter the following command:

    $ ./config.sh
    

    The configuration script starts OUI in Configuration Wizard mode. Provide information as needed for configuration. Each page shows the same user interface and performs the same validation checks that OUI normally does. However, instead of running an installation, The configuration wizard mode validates inputs and configures the installation on all cluster nodes.

  2. When you complete inputs, OUI shows you the Summary page, listing all inputs you have provided for the cluster. Verify that the summary has the correct information for your cluster, and click Install to start configuration of the local node.

    When configuration of the local node is complete, OUI copies the Oracle Grid Infrastructure configuration file to other cluster member nodes.

  3. When prompted, run root scripts.

  4. When you confirm that all root scripts are run, OUI checks the cluster configuration status, and starts other configuration tools as needed.

4.3.3 Configuring the Software Binaries Using a Response File

When you install or copy Oracle Grid Infrastructure software on any node, you can defer configuration for a later time. This section provides the procedure for completing configuration after the software is installed or copied on nodes, using the configuration wizard utility (config.sh).

To configure the Oracle Grid Infrastructure software binaries using a response file:

  1. As the Oracle Grid Infrastructure installation owner (grid) start OUI in Oracle Grid Infrastructure configuration wizard mode from the Oracle Grid Infrastructure software-only home using the following syntax, where Grid_home is the Oracle Grid Infrastructure home, and filename is the response file name:

    Grid_home/crs/config/config.sh [-debug] [-silent -responseFile filename]

    For example:

    $ cd /u01/app/grid/crs/config/
    $ ./config.sh -responseFile /u01/app/grid/response/response_file.rsp
    

    The configuration script starts OUI in Configuration Wizard mode. Each page shows the same user interface and performs the same validation checks that OUI normally does. However, instead of running an installation, The configuration wizard mode validates inputs and configures the installation on all cluster nodes.

  2. When you complete inputs, OUI shows you the Summary page, listing all inputs you have provided for the cluster. Verify that the summary has the correct information for your cluster, and click Install to start configuration of the local node.

    When configuration of the local node is complete, OUI copies the Oracle Grid Infrastructure configuration file to other cluster member nodes.

  3. When prompted, run root scripts.

  4. When you confirm that all root scripts are run, OUI checks the cluster configuration status, and starts other configuration tools as needed.

4.4 Restrictions for Oracle Berkeley DB

The Oracle Berkeley DB embedded database installation that is included with Oracle Grid Infrastructure for a Cluster 11g release 2 (11.2.0.2) is only for use with the Oracle Grid Infrastructure installation products. Refer to terms of the Berkeley DB license at the following URL for details:

http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html

4.5 Confirming Oracle Clusterware Function

After installation, log in as root, and use the following command syntax on each node to confirm that your Oracle Clusterware installation is installed and running correctly:

crsctl check crs

For example:

$ crsctl check crs
 
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

Caution:

After installation is complete, do not remove manually or run cron jobs that remove /tmp/.oracle or /var/tmp/.oracle or its files while Oracle Clusterware is up. If you remove these files, then Oracle Clusterware could encounter intermittent hangs, and you will encounter error CRS-0184: Cannot communicate with the CRS daemon.

4.6 Confirming Oracle ASM Function for Oracle Clusterware Files

If you installed the OCR and voting disk files on Oracle ASM, then use the following command syntax as the Oracle Grid Infrastructure installation owner to confirm that your Oracle ASM installation is running:

srvctl status asm

For example:

$ srvctl status asm
ASM is running on node1,node2

Oracle ASM is running only if it is needed for Oracle Clusterware files. If you have not installed OCR and voting disks files on Oracle ASM, then the Oracle ASM instance should be down.

Note:

To manage Oracle ASM or Oracle Net 11g release 2 (11.2) or later installations, use the srvctl binary in the Oracle Grid Infrastructure home for a cluster (Grid home). If you have Oracle Real Application Clusters or Oracle Database installed, then you cannot use the srvctl binary in the database home to manage Oracle ASM or Oracle Net.

4.7 Understanding Offline Processes in Oracle Grid Infrastructure

Oracle Grid Infrastructure provides required resources for various Oracle products and components. Some of those products and components are optional, so you can install and enable them after installing Oracle Grid Infrastructure. To simplify postinstall additions, Oracle Grid Infrastructure preconfigures and registers all required resources for all products available for these products and components, but only activates them when you choose to add them. As a result, some components may be listed as OFFLINE after the installation of Oracle Grid Infrastructure.

Resources listed as TARGET:OFFLINE and STATE:OFFLINE do not need to be monitored. They represent components that are registered, but not enabled, so they do not use any system resources. If an Oracle product or component is installed on the system, and it requires a particular resource to be online, then the software will prompt you to activate the required offline resource.

The Oracle GSD (Global Service Daemon) process, ora.gsd, is typically offline. You must enable Oracle GSD manually if you plan to use an Oracle 9i Real Application Clusters database on the Oracle Clusterware 11g release 2 (11.2) cluster. Follow the steps under Section 5.3.4, "Enabling The Global Services Daemon (GSD) for Oracle Database Release 9.2" to active the Oracle GSD Daemon.
