Purpose

Oracle Exalogic is an integrated hardware and software system designed to provide a complete platform for a wide range of application types and widely varied workloads. It combines optimized Oracle Fusion Middleware software like WebLogic Server, Jrockit, Coherence with industry-standard Sun Server and Storage hardware and Infiniband networking. The purpose of this document is to provide specific information around a specific Patch Set Update for that system.

Scope

This document is intended to provide a guide, to senior engineers with strong system administration skills, for patching all the firmware and operating system components of Exalogic compute nodes, storage nodes and switches.

Details

This Document provides information about the Oracle Exalogic Patch Set Update for Oracle VM Server x86-64 (64-bit) for Exalogic X2-2 and Exalogic X3-2 Linux systems running EECS 2.0 in a virtual (not physical) configuration. Before applying the patches included in this PSU, be sure to back up your current installation, configuration files, and any user-specific artifacts.

Prerequisites

1. Review the official April 2014 PSU/CPU : Document ID : 1618213.1 - Patch Set Update and Critical Patch Update April 2014 Availability Document
2. Review the general PSU information for Exalogic in Document ID : 1314535.1 - Exalogic Patch Set Updates (PSU) Master Note

April 2014 PSU Content

This Exalogic Infrastructure patch is cumulative and applicable to Exalogic X2-2 and X3-2 systems running release 2.0.6.0.0.

For customers running JRockit, Coherence, and/or WebLogic Server on Exalogic, it should be noted that, middleware patches are not applied automatically along with the Exalogic PSU installation. Middleware patches are separate installs and are highly recommended yet OPTIONAL. The PSU patch explodes to the following directories. Please make sure to follow the README files for each patch as directed by the README file in the 18174061 directory.

Patch Testing and Application Guidelines

1. Read and review Documnet ID : 1638818.1 - Exalogic April 2014 PSU - 2.0.6.0.1 (Linux - Virtual - Exalogic X2-2, X3-2) Infrastructure Upgrade Guide , for patch installation instructions, known issues and special notes. 
2. Validate patch installation on the TEST system.
1. Apply the patch to the TEST system that is of equivalent capability and configuration as the PRODUCTION system.
2. Evaluate technologies and practices that may reduce downtime and risk
3. Automate steps to reduce human error.
4. Define, document, and test fallback procedures required if a patch must be rolled back.
5. Before and after patch application, perform healthchecks using Exachk script to verify software, hardware, and firmware versions using the Document ID : 1449226.1- Exachk Health-Check Tool for Exalogic
3. Validate patch functionality on the TEST system.
1. If applying the patch to address a specific issue, verify that the patch provides the functionality desired.
2. Verify there is no performance, availability, or operational regression while running workload that is representative to that which runs on the PRODUCTION system. This requires comparing metrics captured before and after patch application on the TEST and against metrics captured on the PRODUCTION system.
4. Apply the patch on the PRODUCTION system.
1. Test application functionality with load if possible
2. Before and after patch application, perform healthchecks using Exachk script to verify software, hardware, and firmware versions using the Document ID : 1449226.1- Exachk Health-Check Tool for Exalogic

Uninstalling Oracle Exalogic Patch Set Update

Oracle recommends that you roll back middleware patches in the reverse order mentioned above. Refer to the component-specific READMEs for rollback instructions. Instructions for rollback are not included for Exalogic Infrastructure in this patch set update. If you run into issues while applying any of the patches or software/firmware updates, please contact Oracle Support.
