Learn Oracle 11g - Real Application Clusters

Configure two identical linux nodes in Oracle VirtualBox for an Oracle 11g RAC deployment, with 8 gb per node, two nics, bridged networking, and shared 10 gb disks.

Learn Oracle 11g RAC host requirements in a Linux environment with two bridged NICs, shared devices, and private interconnect and scan listener considerations.

Explore how Oracle 11g RAC uses user equivalence to install software from a primary node and push it to other nodes, enabling passwordless SSH, secure copy, and key-based authentication.

Learn how secure shell enables passwordless inter-node logins in Oracle 11g RAC, with grid infrastructure automating SSH setup and the authorized_keys and known_hosts files shared across all nodes.

Discover how ssh enables passwordless logins between rack nodes in Oracle 11g real application clusters, enabling automated installations, patches, and day-to-day node communications.

Define CRS requirements for Oracle 11g real application clusters by running the cluster verify utility to perform pre-stage checks on two nodes, validating memory, networking, and group membership.

Learn to install CRS as part of Oracle grid infrastructure for RAC, performing pre-install checks and cluster verification across two nodes, with DNS, SSH connectivity, and storage configuration.

Identify and verify Oracle RAC CRS components, including cluster ready services, cluster synchronization services, and event manager, using grid infrastructure tools across Node 1 and Node 2.

Review asm configuration by initializing unpartitioned drives, creating partitions, formatting them, and enabling oracle asm across nodes, then list and scan disks.

Learn how the voting disk and OCR manage a RAC environment, enabling node heartbeat checks and eviction; discover disk group placement and redundancy best practices.

Define the OCR as the Oracle cluster registry in a RAC environment and explain OCR disks, voting disk, and the role of heartbeat in node status.

Explore how Oracle 11g RAC stores and validates the OCR and voting disks, their locations on asm disk groups, and how node heartbeat and local OCR ensure consistent cluster state.

Define the ASM RAC needs and install and configure the Oracle ASM drivers and grid infrastructure architecture for Oracle 11g real application clusters, enabling shared disks across nodes.

Install and configure grid infrastructure for Oracle RAC, including OCR and voting disk, and set up disk groups, testing SSH connectivity between nodes, and running root.sh scripts in order.

Create an ASM database in an 11g r2 RAC environment by installing and configuring grid infrastructure, then establish disk groups for OCR, voting disk, data, and FRB, validating node visibility.

Verify each node with the cluster verification utility, checking memory, disk space, network, and interconnects, then install and configure the grid infrastructure for cluster using Oracle Universal Installer.

Install the Oracle database software in a clustered RAC environment using grid infrastructure and cluster verify; run the Oracle universal installer on all nodes and complete post-install scripts.

Learn to create and deploy a RAC database on two Oracle Linux nodes using grid infrastructure, DBCA, data disk groups, and Enterprise Manager.

Identify RAC database components in an Oracle 11g real application cluster, verify a two-node RAC environment, and review common versus instance parameters and server control status checks.

Review the database software install using the ptf steps, run the installer in the stage directory, perform prerequisites checks, and install on both nodes before running node scripts.

Learn to use ASMCA to create disk groups in Oracle 11gR2 RAC, evaluating external, normal, or high redundancy for OCR, voting, data, and backups.

Learn to create additional external disk groups in Oracle 11g Real Application Clusters using the s m c a utility, naming data and far away, and adjust discovery paths.

Use the database configuration assistant to create an Oracle real applications clusters database named rco across all rack nodes, with enterprise manager enabled.

Learn how oracle 11g r2 uses the rac scan and grid infrastructure and single client access name to provide a dynamic, round-robin listener failover via server control.

Configure RAC listeners in a grid infrastructure, creating traditional and scan listeners under the GI home, and manage them with server control for reliability.

Learn to manage Oracle 11g RAC listeners with server control, starting, stopping, and checking statuses, including the scan listener and round-robin routing, with listeners enabled by default.

Master SRVCTL to start, stop, and check status of databases, instances, and listeners in Oracle RAC, and control from any node via the proper environment.

Explore how to use SRVCTL server control commands to start and stop databases, instances, and listeners in an Oracle RAC environment, monitor status, and manage cluster components from any node.

Learn to manage Oracle 11g real application clusters by using server control to start, stop, and check the status of listeners, databases, and RAC components across nodes.

Demonstrate using srvctl to start and stop database components in an Oracle RAC environment, check status, and manage instances and listeners across nodes.
