Create the first Oracle RAC node in VirtualBox: name the VM, install Oracle Linux 64-bit, allocate 4 GB RAM, load the ISO, and set two bridged network adapters.
Install OEL 6.5 on node one in a prepared VM, configure public and private networks, DNS, hostname, partition disks, and complete post installation steps including reboot and user creation.
Configure a virtual machine for node 2 in the Oracle 11gR2 RAC quick 2-node guide, mirroring node 1 with 4000 MB, loading the Oracle 6.5 ISO, bridging network adapters.
Install OEL 6.5 on node 2 for Oracle 11gR2 RAC, configure public and private IPs, hostname, gateway, DNS, time zone, set root password, select packages, partitions, then install and reboot.
Prepare os level prerequisites on all nodes for Oracle 11g r2 rac deployment, including internet access, rpm installation, kernel and firewall setup, and Oracle user and directory preparation.
Configure public, private, and virtual IPs on both nodes, edit the hosts file to map IPs to host names, and verify connectivity with ping, including VIP failover.
Configure shared storage for a two-node RAC by creating a 100 GB fixed disk in VirtualBox, making it shareable for ASRM groups cluster files, data, and fast recovery area.
Partition 100 GB of shared storage on node one into three partitions (10 GB, 45 GB, 45 GB) and verify they reflect on node two using fdisk.
Configure Oracle Aasim and ASM disks by creating partitions, mapping them to ASM desks, and assigning desks to assemblies groups, while loading the Oracle Aasim library driver on both nodes.
Configure time synchronization across all nodes using NTP/CTS for identical date and time. Use Oracle's automatic DSH setup to enable passwordless node communication and verify cross-node access.
Run the cluster verification utility before grid installation to validate prerequisites, verify cluster health across nodes, and confirm network, memory, and disk readiness.
Install Oracle grid infrastructure on a two-node RAC, starting from node one, configure DSH connectivity, define interfaces, set OCR and disk groups, run the installer, and validate the cluster.
Install Oracle 11g RAC software on a two-node cluster by unzipping the files, running the grid installer in software-only mode, and performing remote installation to both nodes.
Create a 2-node Oracle real application clusters database using dbca, choosing admin managed deployment; specify global database name, node instances, and asm data storage, then finish by creating the database.
