Install DNS with yum install bind libs bind utilities, configure a forward and reverse zone, start named, and verify client DNS resolution on Oracle Cloud RAC.

Install Openfiler san on a vm. Mount the iso image, configure storage partitions, set hostname and network, adjust time zone, and boot to start services.

Configure open filer to discover the LUN on RAC nodes and map the created volume for booting, including logging in with provided credentials and configuring network access.

Learn to configure the open filer client on rec node one using commands from a provided text file, with troubleshooting notes for common configuration issues.

Prepare shared storage by creating an extended partition and eight 12 GB logical partitions for ASM, install and configure ASM lib RPMs on both RAC nodes, and initialize ASM disks.

Configure ssh for the oracle user to enable passwordless login between nodes on Oracle Cloud for a hands-on real application cluster setup.

Copy and unzip software on Node 1, install Oracle, review the attached document for known issues, apply fixes, and run cluster verification.

Install Oracle grid infrastructure for a new cluster by running the cluster verification utility, reviewing known issues, and guiding the installer through cluster name, nodes, and SSL setup.

Install Oracle database software 12c r2 on RAC by transferring sources, unzipping, selecting enterprise edition, verifying connectivity between two nodes, and running root scripts to complete database creation.

Learn to stop and start Oracle RAC on Oracle Cloud by logging in, checking cluster status on both nodes, stopping the listener and database instances, then restarting in reverse order.

Learn how to shut down an Oracle RAC cluster node by stopping services, checking status, halting the RAC instance on node 1, and restarting after reboot.

Create a stage directory and download the required software to prepare the RAC lab, including Oracle VirtualBox, Oracle Database, and Oracle Linux.

Install VirtualBox and create virtual machines with dynamic disks (50 gb) and allocated memory, then set boot order and configure nat, host-only, and internal networks for rac.

Set up Oracle RAC prerequisites by validating internet access, installing preinstalled Oracle packages from the Oracle repository, configuring DNS and network settings, and preparing the Oracle user environment.

Install Oracle Linux on a VM for a real application cluster by configuring language, hostname, three network interfaces (public, internal, private interconnect), setting root password, and rebooting.

Clone the virtual machine from node 1 to node 2 using a command line method, configure disk, interfaces, and hostnames, and verify dns resolution across both nodes.

Learn to set up and create shared disks for an Oracle RAC environment in Oracle VirtualBox, including creating virtual disks, attaching them to VMs, and configuring partitions and udev rules.

Execute a hands-on RAC installation of the Oracle Real Application Cluster database software on Oracle Cloud. Copy software to the VM, unzip, and run the installer to configure the database.
