Install Oracle Grid Infrastructure for a Cluster. Perform the following installation procedures from only one of the Oracle RAC nodes in the cluster (racnode. The Oracle grid infrastructure software (Oracle Clusterware and Automatic Storage Management) will be installed to both of the Oracle RAC nodes in the cluster by the Oracle Universal Installer.

Build Your Own Oracle RAC Cluster on Oracle Enterprise Linux and iSCSI (Continued). A Tutorial on Using the ALSA Audio API. This document attempts to provide an introduction to the ALSA Audio API. It is not a complete reference manual for the API. This document explains how to upgrade a Cisco IOS software image on Cisco Access Router platforms. The examples provided from the 26 Series Routers also. Configure the AWS Command Line Interface and specify the settings for interacting with AWS. With this flexibility, Karaf is the perfect solution for microservices, systems integration, big data, and much more.You are now ready to install the . Complete the following steps to install Oracle grid infrastructure 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. Typical and Advanced Installation. Starting with 1. 1g release 2, Oracle now provides two options for installing the Oracle grid infrastructure software: Typical Installation. The typical installation option is a simplified installation with a minimal number of manual configuration choices. This new option provides streamlined cluster installations, especially for those customers who are new to clustering. Typical installation defaults as many options as possible to those recommended as best practices. Advanced Installation. The advanced installation option is an advanced procedure that requires a higher degree of system knowledge. It enables you to select particular configuration choices, including additional storage and network choices, use of operating system group authentication for role- based administrative privileges, integration with IPMI, or more granularity in specifying Automatic Storage Management roles. Given the fact that this article makes use of role- based administrative privileges and high granularity in specifying Automatic Storage Management roles, we will be using the . Instead, I will only be defining the SCAN host name and IP address in the hosts file ( /etc/hosts) on each Oracle RAC node and any clients attempting to connect to the database cluster. Although Oracle strongly discourages this practice and highly recommends the use of GNS or DNS resolution, I felt it beyond the scope of this article to configure DNS. This section includes a workaround (Ok, a total hack) to the nslookup binary that allows the Cluster Verification Utility to finish successfully during the Oracle grid infrastructure install. Please note that the workaround documented in this section is only for the sake of brevity and should not be considered for a production implementation. Defining the SCAN in only the hosts file and not in either Grid Naming Service (GNS) or DNS is an invalid configuration and will cause the Cluster Verification Utility to fail during the Oracle grid infrastructure installation: Figure 1. Oracle Grid Infrastructure / CVU Error - (Configuring SCAN without DNS). INFO: Checking Single Client Access Name (SCAN).. This is documented in Doc ID: 8. My Oracle Support web site. If on the other hand you want the CVU to complete successfully while still only defining the SCAN in the hosts file, simply modify the nslookup utility as root on both Oracle RAC nodes as follows. First, rename the original nslookup binary to nslookup. Oracle RAC nodes. Next, if you are using a remote client to connect to the Oracle RAC node performing the installation (SSH or Telnet to racnode. X Server), verify your X1. Logging In to a Remote System Using X Terminal. Install Oracle Grid Infrastructure. Perform the following tasks as the grid user to install Oracle grid infrastructure. Un- check the option to . This will start the . Make any changes necessary to match the values in the table below. Interface Name. Subnet. Interface Typeeth. Publiceth. 11. 92. Private. Storage Option Information. Select . Use the default values provided by the OUI: Inventory Directory: /u. Inventoryora. Inventory Group Name: oinstall. Prerequisite Checks. The installer will run through a series of checks to determine if both Oracle RAC nodes meet the minimum requirements for installing and configuring the Oracle Clusterware and Automatic Storage Management software. If OUI detects an incomplete task that is marked . You will be prompted to run the script as root in a separate terminal session. When you run the script, it raises kernel values to required minimums, if necessary, and completes other operating system configuration tasks. Open a new console window on both Oracle RAC nodes in the cluster, (starting with the node you are performing the install from), as the root user account. Run the root. RAC cluster one at a time starting with the node you are performing the install from. When running root. The final step performed by OUI is to run the Cluster Verification Utility (CVU). If the configuration assistants and CVU run successfully, you can exit OUI by clicking . This is documented in Doc ID: 8. My Oracle Support web site. Instead, follow the instructions in section Configuring SCAN without DNS to modify the nslookup utility. After completing the steps document in that section, return to the OUI and click the . The CVU should now finish with no errors. Click . If you remove these files, then Oracle Clusterware could encounter intermittent hangs, and you will encounter error CRS- 0. Cannot communicate with the CRS daemon. Postinstallation Tasks for Oracle Grid Infrastructure for a Cluster. Perform the following postinstallation procedures on both Oracle RAC nodes in the cluster. Verify Oracle Clusterware Installation. After the installation of Oracle grid infrastructure, you should run through several tests to verify the install was successful. Run the following commands on both nodes in the RAC cluster as the grid user. Check CRS Status. ONLINE 4cbbd. 0de. ORCL: CRSVOL1) . When we install Oracle Real Application Clusters (the Oracle database software), you cannot use the srvctl binary in the database home to manage Oracle ASM or Oracle Net which reside in the Oracle grid infrastructure home. Voting Disk Management. In prior releases, it was highly recommended to back up the voting disk using the dd command after installing the Oracle Clusterware software. With Oracle Clusterware release 1. Backing up the voting disks in Oracle Clusterware 1. The voting disk data is automatically backed up in OCR as part of any configuration change and is automatically restored to any voting disk added. To learn more about managing the voting disks, Oracle Cluster Registry (OCR), and Oracle Local Registry (OLR), please refer to the Oracle Clusterware Administration and Deployment Guide 1. Release 2 (1. 1. 2) . Back Up the root. Script. Oracle recommends that you back up the root. If you install other products in the same Oracle home directory, then the installer updates the contents of the existing root. If you require information contained in the original root. Back up the root. Oracle RAC nodes as root. This article was written using Oracle Enterprise Linux 5 update 4 which uses the 2. The tool can provide better explanations for many issues that occur in clusters where Oracle Clusterware, Oracle ASM and Oracle RAC are running, such as node evictions.
